The TRIANGULAR MONORAILROAD (SUPPLEMENT) Describing Subsequent Proceedings Ike TRIANGULAR MONORAILROAD (SUPPLEMENT) By THOMAS CARL SPELLING Description of Two Subsequent Inventions, etc. Published By THE AUTHOR, 115 Broadway, New York City COPYRIGHT 1915 BY Thomas Carl Spelling Description of Two Important Inven¬ tions Subsequent to the Triangular Monorailroad — Usable There¬ with, Though Generally Useful. The triangular monorailroad is fully described in the booklet on that subject. I will, as part of what follows, describe two subsequent inventions of great importance, all of them to be treated as a single interest for present purposes. It cannot be said that the two inventions technically de¬ scribed in the appended patent office documents are mere extensions of the triangular monorailroad covered in the booklet, because these later inventions are adapt¬ able and adjunctive to all means of travel and transpor¬ tation. These would be important and very valuable independently of the monorailroad. And yet it will promptly come to the mind of any one who gives due attention to these matters that if this new form of rail¬ way construction meets an economic need, an important use of the two later inventions will be in connection there¬ with. In the booklet, it is pointed out that trains on the monorail may, because of the absence of friction and bet¬ ter retention of momentum, ascend grades much steeper than would be possible for trains proceeding on two rails ; and the reasons are there stated. But it is evident that the qualities which make that practicable would fall short of meeting the necessities of the situation where the 1 grade is not only steep but of considerable extent, as where it is desired to reach the apex of a mountain range. The improvement embodied in Appendix A hereto con¬ sists in the provision of a rack and cog wheel which will continue in engagement, automatically, while the wheels are traversing curves, and regardless of the rocking of the wheels. That feature is new, important and valuable in connection with either a monorailroad or a two-rail road. It will be noted that, in its main feature and essence, the other invention, embodied in Appendix B, is a mere extension of and improvement upon the principle of the continuous frame and peculiar triangular form of over¬ head support. A valuable feature of this new plan for rack and cog¬ wheel consists in the fact that the same engine or motor which draws the train over the part of the track provided with the toothed racks can be used without interruption or change on the main track where no such racks are re¬ quired. Heretofore, engines specially constructed had to be substituted when the specially constructed por¬ tion of the road was reached. It will be seen that the submerged tubular construction shown in the drawings and described in one of the specifi¬ cations of Appendix B will answer the double purpose of a bridge and tunnel, and can be constructed for much less than the cost of a bridge. And it can be put across anywhere, regardless of the width of the waterway. It can connect the respective territories to be served at any desired point, whereas the narrow point must usually be selected for the bridge For instance, a half dozen rail¬ roads, at present served with terminals on the Jersey shore but having none in New York Citv, could avail themselves of such a facility to deliver freight and passen¬ gers in New York, instead of at Jersey City, Hoboken, Weehawken, etc. A bridge across the Hudson River to connect New York City with New Jersey, and to cost $100,000,000, has been long talked of. But the method here described of uniting the two territories to be served should now be given serious consideration. 2 The tube may be made adaptable to all forms of rail¬ road construction, as will be readily seen and compre¬ hended, if one takes the trouble to read and consider the appendices hereto. It would constitute too much of a diversion if I attempted to describe in detail the con¬ structive work. But sections of the tube containing- sec¬ tions of the structure will be completed on shore and low¬ ered by cranes into coffer dams, after by means of the latter, the support, whether of concrete, earth or pillars, for a corresponding length has been prepared. The de¬ tails can be specified by any experienced engineer or contractor. Since the booklet, entitled "The Triangular Monorail- road," was published in December, 1914, the feasibility, cost and economy of it as a transportation plant have been discussed with numerous men of affairs. The only reason its successful career has not begun in visible and tangible form is the timidity of some who took the trouble to inject into the subject the prevailing industrial and trade depression. In other cases their ultra-conservatism barred the way. They refuse to believe that the old way of doing things can be improved upon. It is the policy of the large majority to wait until others have reaped the cream of the profits, always appropriated largely by the pioneer, before becoming themselves interested finan¬ cially. And the more important an invention the more distinct and general is this strange trait of human nature. But, often, the same individual is wofully inconsistent. He will invest thousands, or millions, in enterprises, not founded on any new idea or invention, in the presence of known and demonstrable hazards. In this instance, a few such have refused to accept the positive assertions of well- known and reputable engineers and manufacturers as to feasibility, workability and cost of construction. In spite of the opinion of experts that the cost per mile of a line of over 25 miles, for construction and equipment, would not exceed $7,000 per mile, and would be even less for a long line, one party said. "Why the cost will be pro¬ hibitory." Another, losing sight of the fact that the only form of stress or force exerted on the monorail is a verti- 3 cal and steady pressure, with only the slightest friction or concussion, and that it is in continuous contact with firm nether support, said: "Your rail must do the work of two rails ordinarily in use ; therefore it must be twice as large." Another, losing sight of the fact that the only Teason for grooving or dishing the side supports is to in¬ crease their strength, and taking it for granted, without examination of what was set forth by me, and contrary to the fact, that the groove was in fact a trench just ample to accommodate the thickness of the horizontal wheel, also of the fact that there is no irregularity in the plane on which the vehicles move, said : "When the engine or car strikes a depression, it will break these side rollers right off." These horizontal rollers turn between upper and nether lubricated plates with which they lightly con¬ tact. The plates are circular in form exteriorally extend¬ ing almost to the circumference of the flat surface of each wheel. By this contrivance, the wheels are made to move forward in an absolutely straight line and without fric¬ tion. Another said that trouble would be encountered when it came to constructing the line across public roads and on streets. The character of the structure is such that that difficulty promptly suggests itself to the mind. While the modification for use as an elevated line in cities was described in the booklet (pp. 24 and 25), little attention was paid to highway and farm crossings. But specific construction in both these latter situations is described in Appendix B hereto. Another, one whose professional avocation would imply a better practical knowledge of things mechanical, said: "But the running of a train in the structure will cause it to topple over bodily." When it is considered that for a train to leave the enclosure involves either the breaking short off of all the longitudinal parts at the same point in the same in¬ stant, or the upsetting of the entire frame throughout its entire extent, such a suggestion seems positively silly. Still another said he could not understand how three rails could cost less than two. But as he must have paid no attention to what he had reacf or might have read, in the 4 booklet, no attention need be paid to his irrelevant crlt- cism. Another was a sweeping objection that the amount of material required, whether of steel, iron or wood, or of combinations of them, would be very great and result in great cost. That objector had given no consideration to the subject of the distribution of strains and stresses which is here so important an element. The force to be exerted by a moving train in this structure is distributed at any immediate point among a plurality of members, while the utmost force exerted at any point is checked and minimized by the inertia of the whole train through¬ out its entire length. Nor is the entire propulsive force of the whole train borne by a definite part of the struc¬ ture. It is distributed for an indefinite distance behind and ahead of it. No such distribution is provided for in any other form of transportation mechanism. Instead of the massive girders columns and beams now seen, for in¬ stance in bridges and on elevated lines, bars and rods of very moderate sizes will be ample. Let the fact be not overlooked that the dominant idea in the invention is the triangular formation of a continuous frame which dis¬ tributes strain and utilizes tensive strength, permitting all the parts to be comparatively small. There are certain phases of the matter to be provided for when actual construction is undertaken so easily at¬ tended to that it was not thought necessary to discuss them in the booklet. One party, being unable to urge any other objection said he did not see how trains could be switched or pass each other if they met on a single track. But it is obvious that a short section can be built on a platform on which is also a curved section, the plat¬ form resting on rollers on which it can be moved at right angles to the roadway. Instead of firmly jointing in the straight section it may be simply locked in. If it be de¬ sired to run a train out on a sidetrack structure, the straight section is unlocked and rolled out. Simultan¬ eously and as part of the same action the curved part is moved in, which being in place connects the part of main track containing the train with the switch track. If in- 5 stead of being a switch it is a branch line, the action is the same. In the one case the train proceeds on its way over the branch line. In case it be the meeting of two trains, then after one train has taken its place on the sidetrack the platform is moved again, the straight section being re¬ stored, whereupon the unswitched train proceeds on its way. The whole process is then repeated to allow the side tracked train to continue to its destination. Another was curious to know how the cars were to be loaded or unloaded and taken care of at terminals. I deem it un¬ necessary to go into a long explanation of a phase of the matter so free from difficulty. Indeed, this form here has many marked advantages. A collection of cars and engines at a terminal needs no separate warehousing structure, in the form of sheds or buildings. The structure in itself can be treated as the framework of a building and either covered permanently at terminals or used to sup¬ port temporary covering. It may be merely the good fortune of a few that many others carry closed brains. But if so it is also provi¬ dential that one or more open-minded individuals can always be found. These become the beneficiaries of new ideas and the financial leaders of their time. No tangible object is ever removed at will from one place to another without a machine, except such as can be effected by the human body in the exercise of its members. Even when a domesticated animal is used, it becomes, for that purpose, a mechanical agency. Why not then employ a perfected machine? The principal obstacles to artificial locomotion are inertia, gravitation and friction. But when inertia is overcome, gravitation is also taken care of. The advantages of the triangular monorailroad in the economy of power is fully shown in the booklet. Fric¬ tion, resolves itself into wear and tear, discomfort, depre¬ ciation of value, profitless investment and danger. But these phases of transportation are greatly minimized, or almost eliminated, in this new form of construction, as is shown in the booklet. If we ignore all else except the proposed new method of track elevation, that alone is a valuable suggestion, not 6 to speak of it as an invention at all, even when we lay tnc monorail idea out of mind. How about provision within the same continuous frame for rapid transit and comparatively slower mo¬ tioned vehicles, etc.? Altogether it will cost less mile for mile than the construction of a good cross-country dirt road, and a great deal less per annum for unkeep. And the peculiar position and corelation of the parts so distributes the strains and stresses that all the advantages of a bridge across depressions, roads and farms can be realized, with no more cost above that of surface construc¬ tion than is involved in extending the perpendicular members downward to solid bases and putting on the diagonally criss-crossing side braces. This is also an important facility for guarding against external collision, from which a few wires or a wire- netting attached to the supports affords complete protec¬ tion. In five years over thirty thousand persons who were neither passengers nor railroad employees were killed in railroad accidents, having been struck by trains. During the same period there was an enormous loss from the killing and crippling of domestic animals. The pecu¬ niary losses aggregated an enormous sum. Is not a plan of construction and operation which obviates all that worth considering on that account, even if only for that utility ? Two years ago, the Interstate Commerce Commission referred to the fact that the use of elevated structures in cities had done much to reduce the number of accidents and fatalities in cities. In that suggestion there is much food for thought relevant to the present subject. There are a score or more of serious injuries to persons and sev¬ eral fatalities daily in New York City alone due to street cars, automobiles and other surface transportation. Tak¬ ing the whole country over such accidents with serious or fatal results far exceed those on the steam railroads. There is, of course, no means of ascertaining the money loss from breakage, wear and tear of vehicles, streets and roads, but it runs into hundreds of millions. Nearly all of this loss would be obviated and convenience and com- 7 fort greatly promoted by the use of this partitioned facil- it>'- Now I will briefly refer to the use of longitudinal mem¬ bers in lieu of ties. If you should investigate where the truth can be elicited from disinterested sources, as in the reports of the Interstate Commerce Commission for 1911 and 1912, you would learn how serious is the cross-tie problem. You will also find a description of futile at¬ tempts to solve, by the provision of substitutes ; that neither stone nor concrete will do, because they lack re¬ siliency and are too brittle ; that there are insuperable ob¬ jections to paper or pulp, and so forth. But you will find that no one down to the date of applying for this patent had thought of using wooden sills attached to cross bars, in connection with a continuous and unyielding super- structural adjustment which prevents the vehicles push¬ ing apart the track where the lunge of a heavy engine occurs, or bending or disjointing a rail and causing a wreck. This plan making feasible the substitution of longitudinal sills for ties, whether pursued in constructing the one rail or the other kind of railroad, is covered in the specifications and claims. Every day's delay in be¬ ginning construction and operation on the plans so set forth is a wasteful consumption of valuable time. Even if the two-rail method should be adhered to, the combi¬ nation of the railroad, automobile and carriage way, foot path and conduit for wires, pipes, etc., must soon come to stay. No one can calculate how much further the country would have progressed in prosperity had these improvements been adopted thirty or fifty years ago. The course pursued by the railroad oligarchy with ref¬ erence to the triangular monorailroad invention justifies a brief discussion by me of the country's railroad situation. My every move in this matter has been watched by the railway magnates and their backers. Both their avowed representatives and their spies have called on me and endeavored in various ways to ascertain my plans and to tie up myself and my inventions. They charge up to these inventions, and to the limited publicity given the first two, some of their difficulties in the financial mar- 8 kets, and with legislative and administrative bodies. To all of which I must, in part at least; plead guiltv. They are putting forth stupendous efforts to forestall me by increases of rates, which means the accumulation of large surpluses, some of which have been already made and approved by the Interstate Commerce Commission, with other increases in contemplation. The plea which they made for increases to recoup them for dull business and weakened credit resulting in part at least from foreign wars was of course absurd, in view of the fact that all other interests were suffering even more. But, though they have an army of lobyists, attorneys, officials, hire¬ lings, publicists and writers boosting and rooting for further increases, the freightpayers of the nation have somehow divined the truth. Commissioners and other officials who adopt the railroad view in this matter are tempting the mighty undercurrent of public sentiment and are likely any day to find themselves legislated out of office in compliance with an irresistible popular de¬ mand. In these days a great deal is being publicly spoken and published by railroad officials and other spokesmen for the railroads and in favor of further aggrandizement of the railroad interest. The idea sought to be firmly im¬ planted in the public mind is that one great need is the upbuilding of railroad credit as an indirect but short way to the restoration of business prosperity. But the real cause of decrease in railroad profits may be also the cause of still greater distress of the freightpayer. so that the extra dollar with which to pay the increased rate or fare may be much harder to earn than heretofore. Very little has been said or published on that phase of the matter, and subservient official bodies have given it scant con¬ sideration. In saying here that the matter of rates and fares is the most important with which the government has to deal, I only echo what is said by railroad officials, though I stand in direct opposition to them with respect to the proper treatment of it. The railroad view has been ex¬ pressed some thousands of times, but I must limit myself 9 to a quotation of the latest expression. In a recent news¬ paper interview, Mr. A. L. Mahler, President of the Union Pacific, declared that more revenue, to be obtained only by rate increases, is necessary to protect the securi¬ ties of many lines. The significance of this is that, ac¬ cording to his view, rates should be sanctioned adequate, under all circumstances, to sustain railroad stocks and bonds in the markets of the world. Rules for making and maintaining rates which both federal and State com¬ missions and courts have established already tend strongly to an acceptance of this pro-railroad standard. The twenty billions of steam railroad securities and the fifteen billions of municipal utility issues will have to stand in the same category in order to avoid chaotic financial conditions. To have the one practically guaran¬ teed by the federal government and the other left to the vicissitudes of the stock market would be a disjointure fraught with disastrous consequences. Here then is a situation of immediate concern to all the people of this country. With fixed interest charges, and dividends standardized at rates above the normal interest rate, on thirty-five billions of dollars, saddled on them, wherein will the conditions of European peoples, staggering under the burdens of war, be worse than theirs? And yet their attention is being diverted to the miseries of other coun¬ tries whilst this stupendous imposition is being consum¬ mated in their own. Corporate dividends and interest are eating up this country, just as are taxes in other coun¬ tries. And since American rates are higher, they will eat more ravenously and rapidly here than elsewhere. The proposition that governments, in the exercise of a regulating power, must not exercise it below a line which marks the base of an unreasonably hight rate and separ¬ ates it from a reasonable rate, and must never sanction a rate which would appear to the rate-regulating body un¬ reasonably low, is of far-reaching effect and monstrously vicious. It requires no statemanship, nor a legal or sci¬ entific mind, to understand that it puts the government in the position of an underwriter, guaranteeing fixed in- 10 comes on oceanic issues of corporate stocks and bonds in which the general public have no definite interest. What rates adequate for the purpose stated are to be is indicated by recent events. The firm of financiers which negotiated a loan to France of $50,000,000 also undertook the negotiation of a loan of a loan of $100,000,000 to the New York Central Railroad, and said that foreign gov¬ ernments were borrowing here at 7 and 8 per cent. Dur¬ ing the year 1915, over a half billion dollars of short term notes issued by the railroads must be met, and most of them are held in countries which are borrowing here at rates which the railroads must meet. An influential New York newspaper, subserviently friendly to every railroad interest, commenting editorially, stated the rail¬ road view of the situation substantially as I have inter¬ preted it, and then added these significant words: "There cannot be general prosperity without prosperity for the railways, and they are hard pressed in the same manner as foreign borrowers of the highest credit." We marvel at the folly of European rulers who brought on these horrible wars ; but their folly scarcely equals what will be that of the people of the United States if they permit this process of financial absorption and mastery to proceed to its finality. The average annual net profit in the form of permanent additions to capital, according to Adam Smith, did not in his time exceed three per cent. It has increased in our day, but does not now exceed an average of three and one-half per cent., embracing all forms of capital embarked in business. It should not be difficult to figure out how long it will take thirty-five billions of public utility capitalization, that being about one-third of all capital, or its representation, drawing from all other business over seven per cent., to absorb or destroy it all. Of course no one believes it can go on. All know that the process, as manifested in con¬ stantly increasing rates, must halt and that lower rather than higher rates will be demanded. And the conse¬ quences, both to public service interests and the public, will be less serious if halted now than later. The proposition that investors in corporate stocks are 11 entitled to have secured to them a reasonable return, equal to or a little above the ruling rate of interest is so plausi¬ ble that it finds a ready acceptance by those who do not take the trouble to investigate the subject historically and legally, or to study its operation economically and socially. The business of public utility corporations is regulated because of its public and monopolistic charac¬ ter, both as to practices and rates. But by regulating it, no resulting duty or obligation is incurred by any gov¬ ernment with respect to rates, except that the constitu¬ tional prohibition against confiscation shall not be vio¬ lated. And there is a very important and material differ¬ ence between a low, or an unreasonably low, rate and one that is confiscatory. The distinction was clearly pointed out in earlier decisions by the Federal Supreme Court, which held that so long as some profit remained, how¬ ever small, or so long as there was no actual loss from operation, a legislatively or commission-made rate was not objectionable from a consitutional point of view merely because it was low, or even unreasonably low. -But, latterly, corporate and capitalistic influence has made as great progress in the courts, as elsewhere. The latest view can be found in recent decisions by the Supreme Court and in promulgations from the Interstate Com¬ merce Commission. Now let any one engaged in a private avocation of any kind, anywhere, reflect upon the advantages of having the general government or his state standing as security to him for a given fixed income from his business. Even if it were as low as three per cent., with the privilege of making as much more as possible, the guarantee would at least secure him against insolvency, and if onlv to that extent, be exceedingly valuable. Let him also reflect that the guarantee of governments to public utility corpora¬ tions to be made good through rates, is much more than three per cent., and even above the prevailing rates of interest. He will then be ready for the next step in the train of reflection, namely, he has no such security; only public service corporations enjoy it. As for the ordinary business man, or farmer, or wage earner, he is left to all 12 the vicissitudes and hazards of his environment, exposed to possible bankruptcy from competition or from other causes. The foregoing statement of an existing situation is a proper argument in favor of public interest being taken in these inventions, the most important and comprehen¬ sive ever patented in any nation. When I take into con¬ sideration the fact that political action is largely con¬ trolled by banking and railroad syndicates representing combinations, that progress has been and is being made toward a complete subordination of official to financial policies, I feel justified in calling attention to it and sug¬ gesting as an alternative the construction of this mechan¬ ism, to escape general impoverishment of the masses on the one hand, or government ownership of all public utilies on the other, just as I would suggest the opening of a sluiceway to prevent the bursting of a dam in a large stream and wholesale loss of lives and property below. Discussion of the broader phases of the railroad ques¬ tion cannot of course be here extended, but I cannot for¬ bear calling attention to the fact that the zeal of some of the railroad officials in advocacy of increasing rates has led them into disclosures of their ultimate purpose. They say that 100,000 miles of new lines or feeders are now needed, and without these increases of rates and fares to replenish their surpluses they cannot be constructed. The fact that the present lines were first built or subse¬ quently paid for by the public has been, to a great extent, suppressed so far. The parasites who own the stocks and thrive on dividends now demand that their properties be further improved by additions and extensions, with other people's money. But really the country needs, not 100,000 miles of additional rapid transit, but 1,000.000 miles. One hundred thousand miles of the kind of railroad now in use would cost to construct and equip $75,000 per mile or $7,500,000,000, and the fixed yearly dividend and interest charges as heretofore sanctioned bv the Interstate Commerce Commission would amount to $825,000,000. Triangular railroad construction would cost one-tenth that amount, for 100,000 miles and the 13 freight and passenger charges could be reduced one-half and still pay fixed charges according to the standard so sanctioned. Or, at the same cost of constructing and equipping 100,000 miles of the two-rail system, 1,000,000 miles of monorail system could be produced on every mile of which the rates could be profitably fixed at one- half or less than one-half existing rates. In 1906, when the spirit of popular resistance to rail¬ road exploitation was strongly in evidence and the Inter¬ state Commerce Commission felt constrained to con¬ form to some extent to the prevailing sentiment, it was shown by its statistics that of the fifteen billions of dol¬ lars of railroad capitalization nine billions represented nothing substantial, or in common parlance, was water. Since then overcapitalization and looting by railroad managers have gone on more boldly and recklessly than ever, so that of the present capitalization of twenty bil¬ lions it is safe to say that twelve billions represent no substantial investment. And yet the claim is loudly and clamorously made that the people should stand successive increases in rates in order to pay interest and dividends at much above average rates on all these monstrously fraudulent issues. And preposterous as is the idea it finds favor among financiers and bankers and in some commer¬ cial circles. Meantime, the agriculturalists and other toilers, the ultimate freightpayers, appear to be slumber¬ ing. But they will soon wake up, and then we shall have a new reckoning. They are supposed to be politically interested in tariffs, but no form of tariff taxation ever in force meant more than a possible one-tenth the burden of railroad transportation which is $158 per annum for each family. It is fair to admit the counter claim that a large proportion of this impost, that is to say, about two- thirds of it is redistributed. The redistribution is not, however, general, but only among railway employees in the form of inadequate wages and to producers of railway supplies at fancy prices and handsome profits in which railway managers openly, though none the less scandal¬ ously, participate. Then out of the remaining third the interest on bonds and sinking funds are first taken care of 14 and the balance inures to stockholders, either directly in the form of dividends or indirectly in improvements, or additions to their properties. As a rule, neither the properties nor the stocks,—the latter being the paper muniments of ownership,—cost the original owners any¬ thing, and it is no function of government to take care of speculators. The roads were built and equipped with money advanced by the bondholders and the proceeds of federal, state, county and municipal bond issues. The transcontinental lines were presented, first and last, with 250,000,000 actes of public lands, or an area greater than is now contained in the States of Ohio, Indiana, Illinois, Iowa, Minnesota and Wisconsin, which six states have an area of only 242,000,000. By the criminal conduct of lawmakers and executives the promoters and builders were enabled to select the best land, much of which is now held out of the market, fenced off and rented to stock¬ men, whereby homeseekers are excluded from it. Appeals by railroad officials and their cohorts are made to the public to let bygones be bygones and make further sacrifices for railway promotion and extension. It is re¬ markable that such appeals find acceptance and welcome in many directions. I suppose that if the laws against piracy were suspended and a strong-handed band of Cap¬ tain Kidds got control of the high seas, thus becoming financially powerful, therefore respectable, there would be plenty of politicians and business men demanding for them not only immunity but tribute. It may be that, in spite of the dishonest financiering and all the other vices and shortcomings of the present sys¬ tems, they would not only be maintained in their present forms but vastly extended were it not that they are me¬ chanically antiquated and unscientific and did not the near exhaustion of available timber for ties and of iron ores for other parts clearly indicate the inexorable neces¬ sity for a change. Nor is the increasing cost of heat gen¬ erating fuel to be ignored. Well informed people know that the American railway system cannot endure as now projected. President Rip¬ ley, of the Santa Fe, says the whole system is breaking 15 up. The idea that he probably intended to convey was that it is so water-logged that it is sinking. At certain crop-moving seasons there is a shortage of rolling stock, just as there may be rush days and scarcity of salesmen in a store so located or managed that it has no large volume of regular trade. The central and important territory of the country has an over-supply of the prevailing type of railroads. This statement is corroborated by very high railroad authority. President Ripley, of the Atchison, Topeka & Santa Fe Railroad Company, on October 24, 1914, said: "Every night five magnificent trains leave Chicago at practically the same hour for Kansas City. Each train carries every modern device for the comfort of passengers, and not one of them is loaded to capacity. Six trains leave Chicago for Omaha nightly and five for St. Paul, and of all of them the same could be said. Probably one of these trains—certainly two of them—would amply care for al the business and a great saving would result from dis¬ continuing the other four." It is to maintain not only the solvency but dividends on this excessive construction and operation that increases of rates and fares are de¬ manded. But the plethoric rulers of two-rail transportation, and their servants, official and unofficial, had just as well recognize the presence of that which appears to all others inevitable, and conform to it at the earliest practicable moment. Their revenues have been for several years seriously affected by what we may fitly term minor com¬ petition. First came the trolley cars, then automobiles, now the triangular monorailroad. There can never be any major competition, that is to say, there will never be any form of transportation more massive than that now in use, and evolution has recently been toward smaller mechanisms and smaller shipments. There is less gener¬ alizing and wholesaling and there is an immense increase in specializing and retailing. If the introduction of the monorailroad is to be opposed because of its economic or financial disturbance, what is to be done about the in¬ creasing number and spread in the use of automobiles? 16 In 1914, 515,000 cars, valued at $485,000,000, were built and sold in the United States alone. Express companies, a creation of comparatively recent times, made the first inroad. Now we have the parcel post, which is the first governmental recognition of the changing demand. The next step will be the employment of means for turning the parcels post to greater public use freed from de¬ pendence upon existing railroad monopolies. The government will resort to the mechanism herein de¬ scribed. And the former will, to that extent feel their power slipping away. There is, however, a normal open¬ ing in the transportation service for the new form, even if those existing remain. As the extortion and oppression of monopoly grow, desperate poverty resorts to new methods of prying off and sequestering some of the profits of transportation service. This accounts for the recent innovation in the form of five cent jitneys in local service, truly menacing to rapid transit public service companies. The news¬ papers which defend and uphold the companies at all points as to all their policies and practices have taken up the fight against the jitneys, and even gone so far, in some instances, as to advocate repressive legislation. And the irresistible economic tendency in the field of long distance transportation, and the imperative demand for facilities costing less, operated at less expense and per^ forming long distance service at lower rates, will inevitably establish the new forms of construction embodied in these inventions. Few persons have taken the trouble to study the com¬ parative safety and profitableness of investments in the business of transportation, considered merely as such, as to which a few words will be here added to what is said in the booklet (pp. 34-36). There has been recently published a showing of the results of the operation of transportation facilities other than steam railroads. It appears that in every section of this country public serv¬ ice business has exceptionally prospered, and its net earn¬ ings and dividend rates have increased, in spite of pre¬ vailing depression in other lines of business resulting 17 from foreign wars and otherwise. A Supreme Court justice recently made this comment regarding a public utility company from the bench : "An interest in such a business is as near a safe and secure investment as can be imagined with regard to any private enterprise." Thus far little has been said about important minor parts of the structure technically described in Appendix B. The pressing need for just such a postal telephone and telegraph facility as is described in the booklet (pp. 31-32) will be readily seen by all. The other uses can¬ not be overestimated. Surely the governmental depart¬ ment charged with the duty of conserving the revenues cannot be long blind to the advantages thus offered. There is sufficient utility in these minor parts alone to fully justify the expenditure of the entire cost of con¬ struction, even if the parts set apart for railways, road¬ ways, water and power transmission, etc., were not util¬ ized at all. When the booklet was written the inventions embodied in the appendices had not been perfected, and as there are essential features of military uses in this new form of con¬ struction, such military uses were not discussed. But their inestimable advantages in military operations must clearly appear to any intelligent person who is open- minded on the subject. Even if I were competent, it would not be necessary for me to discourse at length on the subject of military operations, strategy and tactics. I need only call atten¬ tion to transportation as a factor therein. Without rail¬ roads and motor cars belligerents are no better off than the warriors of 100 or a thousand years ago. Railroads in the control of one force give it an immense advantage over another without them ; but the advantage is limited and only occasional, in the very nature of things. And so are uses that can be made of automobiles, a very im¬ portant limitation consisting in their cost and the ease with which they can be located and wrecked with artil¬ lery fire. We saw much in the news about the move¬ ments of these spectacular war engines in the beginning of the European War, but as very little or nothing was 18 said about them in the later stages, they must have been found practically useless or too luxurious. And this ap¬ plies with the same force to armored as to unprotected cars. For most purposes, the one is about as helpless and unsafe as the other. Viewing the matter in a broad aspect, let me ask, would not the presence of numerous minor lines of rapid transit, extending in all directions and supplementing the present lines and systems be an immense military advantage, especially when we view it from a defensive standpoint? It is with reference to field operations after the scene of action has become approximately definite in outline that attention should be given to these inventions as military facilities. The military engineer must have been deeply impressed by the weakness of defensive preparations at Port Arthur and the folly which left the crests of 303 Metre Hill and The Eagle's Nest without heavy ordnance with which to oppose advances to the main fortifications. But to have placed the heavier guns there required the cogged wheel and rack, or something performing its function. Many illustrations just as strong were developed in the European War. Had the Germans possessed such mech¬ anisms as the triangular monorailroad, with those shown in Appendices A and B as adjuncts thereto, the result at Steinbach, at Nieuve Chapelle, and at several other strat- egetical points might have been different, and the entire history of, and sequel to, the war might have to be writ¬ ten every differently. Without particularizing, I may say, generally, that modern warfare is not merely a matter of the number or of the fighting quality of men but more strikingly one of the best machinery. The vast machine on either side is made up of both animate and inanimate integers. All know that transportation machinery is in full sense vital to a people in times of peace, and that it is doubly so in times of war. An army has no advantage merely because it has longer guns better manned than the opposing army if it have no means for mobilizing them. On the other hand an army has an advantage if better able to rapidly move, shift and use its guns, though 19 they may be of less calibre and less effective on reaching the target than those of the opposition. The movement of troops, munitions and supplies, are of equal importance. I am not bound to assume that the United States will very soon or remotely become engaged in hostile conflict with foreign nations. I need only point to the settled policy of keeping the country in a state of preparedness for such a contingency. And I will first call attention to the use that could be made, in the event of such conflict, of the cogged wheel and rack. Without a cogged wheel a traction power only equal to the cohesion between two smooth surfaces produced by the weight of the engine is available. Consequently only very moderate grades can be overcome. Heretofore, in the use of cogged wheels, the contact has been such that there had to be an exact correspondence between the rack and the toothed part of the wheel. And loss of contact caused, for instance, by a rocking of the wheel or any sidéral movement, threw the teeth of the wheel out of the rack, so that either a serious accident resulted or the train was halted until machinery could be brought to jack the engine back into alignment. There was no such thing as a curved rack, or toothing adaptation thereto. Consequently, only such elevated points could be reached as were accessible by moving on straight lines. Of course there are ascents so steep that they cannot be directly made bv using any cogged wheel device, and there are moderate elevations to which the approach must be on lines of irregular gradation, necessitating curves, and because heretofore no such device adaptable to curves was provided, they could not be made at all. Almost any elevation may be attained where vehicles can be drawn on a railroad which is zigzagged. The invention described in Appendix A meets these requirements. The teeth and rack with which they contact are in a form insuring con¬ tinuous engagement, in spite of turns to right or left, and in spite of lateral oscillation. The triangular mono¬ rail form of construction is vast economy and efficiency herein, but, for the benefit of adherents to the existing 20 antiquated and wasteful form, I will reiterate that this in¬ vention is as adaptable to the one form as to the other. With existing means of transportation heavy guns and their equipments cannot be carried to any point consider¬ ably elevated at all, and only to moderate elevations at great cost and with consumption of much time. By use of the plan of this invention, especially with the triangular monorailroad form of construction, they can be in a few hours or in a few days, at most, placed in as elevated situations as are ever desirable, and their efficiency thereby immensely increased. No one will be able to fully appreciate the possibilities of these inventions in military use without keeping in mind the uniformity and continuity of the triangular structures. In defensive or offensive preparation, all the parts can be kept in stock or quickly manufactured to order bv pattern, and then, upon emergency, put together speedily. The divisional roadway structure embodied in Appen¬ dix B also contains important points of novelty and utility when viewed as a military facility. Not many years ago much doubt existed whether lines of subway construction and operation for local travel were feasible within any permissible cost. Since then steel tubes of large space areas have been constructed, not only under streets and buildings but under the Hudson and East Rivers. Through them trolley and standard guage trains are constantly and safely run, both ways. These tubes reach a depth of 70 and 80 feet below the surfaces of the rivers, being extended through mud and quicksand. Such depths were sought in order to reach below the extremest depths of the streams. And the question arises why they were not simply imbedded in the bottoms of the rivers until the deepest channels or deep¬ est recesses were reached and then simply extended across through the water. A depth of 40 feet, or even 35 feet would be beyond any possible interference with navigation. There may have been other reasons, but one important reason probably was that the tubes as then projected were not self-supporting in suspension, that is 21 to say, they had to have solid nether support at all points. Governments should interest themselves in these in¬ ventions. Our government should view them not merely through the eyes of the Secretary of War, but from the viewpoint of other departmental chiefs as well. Indeed, it would be difficultt for me to say which department I think should have the greater interest. When I think of our immense mineral and timber resources, unavailable because destitute of transportation facilities, I think of the Interior Department. When I reflect on the backward¬ ness of agriculture, its attendant wastes, and the need for its scientific and intensive development, I think of the Agricultural Department, in this relation. And I re¬ spectfully call attention to one item among many that might be mentioned. These farmers need, above all else, abundant and cheap fertilizers. The supply of these is now controlled by a trust having various plants. Few farmers are able to obtain needful nitrates and phosphates because of high prices and prohibitive rates. The Postoffice Department expends a sum each year for carrying the mails which added to what the people pay excessively for interstate telegraphing and telephon¬ ing would equal the cost of constructing, equipping and operating for postal telephone and telegraphic purposes alone, twenty thousand miles of the triangular monorail- road. I have not mentioned the huge Departmental payments for telegraphing and telephoning which might be thus saved. For all its uses, the smaller triangle would be ample. In case the government did not care to engage in railroad transportation, it could lease the main roadway and its equipment for as much more. The sides, and the roof and floor of present subways and tubes are of a thickness which involves a needless and wasteful investment which are avoided to a large ex¬ tent by arranging the internal supports as shown by the drawings and specifications of Appendix B. And, in crossing broad waterways, under water, in lieu of a continuing nether support, parts of the internal frame¬ work are extended downward at intervals to points where solid support exists or can be created. Where merely 22 laid on the bottom, or extended across deep recesses, the tubular parts need be only of sufficient thickness to resist the water pressure, but for actual subway uses would have to be of increased thickness. Where actually con¬ structed underground, the form of the structure will be more substantial with much less cost, and the partitioning economizes space and allows passageways for various uses as described in the specifications. I cannot engage in such extensive discourse as would describe what might have been accomplished aggres¬ sively or defensively along the Yser and upon other scenes of European conflict, or adjacent to the Darde- nelles, by the prudent and timely use of some or all these various new facilities, nor fully as to what might be done therewith by our own government. But space can be given to the asking of a few questions. Would it not greatly strengthen the defenses around New York, or San Francisco, or any other of our large cities, if artificial thoroughfares were constructed on the supporting beds of the adjacent waters for not only slowly moving vehicles and pedestrians but rapid transit power engines and trains? Would there be anything fantastical or imprac¬ ticable in a suggestion that the emplacement and removal of heavy ordnance could be better provided for than at present? To give point and pertinency to this question, I call attention to a recent news item to the effect that in an attempt to place a 14-inch gun on elevated ground in the Necos Island near the Panama Canal, the chains slipped. The gun and its carriage rolled to the bottom of the acclivity, and one of the many men engaged in the effort to elevate it was killed. That was just one of the many guns necessary to fortify the place. Probably mil¬ lions have been needlessly spent in doing such work in that crude way. All the parts of a section of the cogged wheel and rack construction sufficient for quick and economical emplacement could have been carried on the ship that carried the guns and their carriages. And where one or more strategetical points around a seaport city or in a field of definite military operations supplement and mutually depend on each other, would it not be quite a 23 convenience and advantage if some reasonably cheap and amply protected connection were made between them, such as can be provided by the partitioned continuous frame, with the unprotected parts placed under the earth surface, or underwater? It is important here to keep in mind the adaptability of this form to any dimension and quality of material, to meet the necessities of any par¬ ticular case. And I again call the attention of sticklers for ancient forms and methods to the fact that the inven¬ tions described in Appendixes A and B are as available for two-rail roads as for those of the monorail type. The fact should not be lost sight of that the wasteful, burdensome and unscientific character of the two-rail open overhead system has been recognized for years. The one rail with wheels moving thereon in single file and overhead confinement was seen to be a vast improve¬ ment, if that could be consummated. But, heretofore, no means, for meeting the latter need had been discovered. And it is worthy of note that no one has thus far had the temerity to deny that the overhead requirement is fully answered in the triangular arrangement, or to claim that it is not adaptable to every need in point of strength and resisting power. In each large city in the United States, and elsewhere, there is a need of long standing for enlarged local rapid freight transportation. Most large cities cover many square miles of territory and the interchange of freight between railroad terminals and stores and warehouses, and between manufacturers and distributors, a business of vast proportions, is now done wastefully as regards labor and expense, not to mention the public expenditure for repair and reconstruction of streets. Much of it could be avoided and the public comfort and convenience sub¬ served by the construction of belt and cross lines accord¬ ing to the forms described in Appendix B. Vast benefits could also be enjoyed in the other utilities therein pro¬ vided for, a description of which will not be here re¬ peated. Nor is it necessary to here repeat arguments up¬ holding the superiority of the triangular monorail form of construction for the rapid transit compartment of the 24 structure, since all the advantages of the latter as fully appear whether one rail or two supportings rails be em¬ ployed. Nor is it necessary to argue the comparative advantages of the elevated over the subway plan, or vice versa. When the idea of lighting London by the combustion of gas made from coke was first broached in Parliament, it was denounced by Lord Cavendish as preposterous, and he remarked that it was an insult to bring such a fantastic proposition before the House of Commons. There may be many Lord Cavendishes in our govern¬ ment today. Whether there are or not remains to be seen. When Bessemer read his essay describing a new process before a thousand ironmakers, he was derided and hooted, by all save one. That single exception had an open mind, and he became a multi-millionaire. The minds of the others had been "queered" by the failure of previous efforts to do what Bessemer had succeeded in doing. So, many may now close the avenues to their minds when the subject of the triangular monorailroad is presented because of knowledge that other monorail structures have broken down in use. To all such, I ex¬ tend an invitation to open their minds for the reception of a new idea. 25 Appendix A SPECIFICATIONS AND CLAIMS. This invention relates to improvements in monorailroads of the general type suggested in my patents Nos. 1,058,481 of April 8, 1913, and 1,105,540 of July 28, 1914. The object of the present invention is primarily to provide for use in a monorailroad system, though capable of service elsewhere, an improved combination of traction wheel and rail designed to assist in overcoming possible objections flow¬ ing from the travel of a car over regions including steep grades, as in ascending a hill, either in a straight inclined plane or by a circuitous route. In the construction exemplified in my above mentioned patents, the rail therein employed had a smooth tread and the traction wheel both smooth periphery and flanges. This construction is obviously, at all times, desirable in approxi¬ mately level country, or where but relatively slight inclina¬ tions are encountered, and my present aim is to maintain this desideratum while at the same time improve the co-operating elements, so that, as distinguished from the mere frictional traction engagement, I obtain an interlocking or positive traction engagement between the wheel and rail when travel¬ ing up severe inclines. An ancillary feature of the invention embraces the pro¬ vision of means enabling relative bodily shifting of the trac¬ tion wheel laterally of its rail,—as when the car sways in turning curves,—while retaining a positive or interlocking traction engagement between the wheel flange or flanges, and complementary portions of the rail member. The foregoing and other advantageous characteristics of my improvements will more fully appear from the detailed description hereinafter presented, when read in connection with the accompanying drawings forming part hereof, and wherein several preferred embodiments of the invention are illustrated. 26 In the drawings. Figure 1 is a transverse sectional view through the frame¬ work, and associated parts, constituting the way within which a car may travel, the car being shown in elevation. Fig. 2 is an enlarged detail vertical sectional view of the rail and co-operating traction wheel. Fig. 3 is a side elevation of Fig. 2. Fig. 4 is a side view of the rail and wheel. Fig. S is a view similar to Figure 2, exhibiting a modified construction of the rail, and Fig. 6 is a like view of a further modified construction. Referring more particularly to the drawings, wherein like reference characters designate corresponding parts in the several views, and first with reference to the first four figures, A represents the framework of a monorailroad, the same be¬ ing of approximately triangular formation; B is a car of any designed type adapted to pass through the frame; C are a pair of lateral rails extending along the frame; and D are yieldable buffer wheels or equivalent devices, not necessary to be specially defined herein, adapted normally to center the car, but permitting the same to yield under a cushioning in¬ fluence when the car sways in rapid travel, and especially when rounding curves. The buffer wheels D traverse grooved portions of the rails C, as shown. E represents the driving traction wheels supporting the car and arranged centrally thereof, and similarly centrally of the base portion of the framework in position to engage the corespondingly centrally disposed rail F. Of course, any number of traction wheels may be employed, in keeping with the requirements attending any particular service, or type of car, it being deemed sufficient to typify the same by the in¬ clusion of but one wheel in this application. The traction wheel or wheels are driven through the medium of any known or preferred source of power. The rail F is provided with a broad strong central portion G merging at its lower opposite edges into securing flanges F, utilized in fixedly securing the rail with reference to the framework in any practical and efficient manner. Projecting upwardly centrally of the rail is a broad rounded tread por¬ tion J, the same being smooth on its upper surface to re¬ ceive the correspondingly shaped base K of the peripheral groove in the traction wheel E. At opposite sides of the tread J, the base portion G of the rail is curved downwardly and outwardly, as at L, and the sides of the tread portion are curved outwardly as repre¬ sented at M, to gradually merge into the curvature of the upper surfaces L, to which I have just referred. These upper surfaces L and the lower portions of the side walls of the tread member J are formed into similarly curved teeth N, adapted to constitute racks along the two sides of the said 27 29 tread member, and the traction wheel E is formed peripher¬ ally of its flanges O with teeth P to convert said flanges into a double integral gear, as will be readily understood. The flanges are rounded, as shown, to dispense with corners at the opposite ends of the teeth. From the construction thus far defined it will be appreciated that when the traction wheel E traverses the usual smooth-tread rail, as shown in my prior patents, the flanges O will be free with reference to their peripheral portions, and relative to the securing flanges of the rail, so that the only bearing between the wheel and the rail will be on the top of the smooth tread and between the same and the smooth base portion K of the groove in the traction wheel, so that in passing over approxi¬ mately level country of comparatively slight undulations the toothed portions of the wheel flanges perform no action, and all of the advantages incident to a smooth tread and smooth wheel accordingly preserved. When, however, se¬ vere or steep inclinations are encountered, it is my purpose to install suitable sections of the present improved type of rail to permit engagement of the gear portions of the trac¬ tion wheel with toothed racks, and hereby provide a posi¬ tive interlocking connection and drive or traction between the wheel and the rail until' the summit of the inclination is attained, when the cars may pass on to other continuations of smooth rails, if desired. It will also be apparent from the disclosure herein made, that swaying of the car in turning curves on up grades, while effectually maintaining the double gear wheel in mesh with one of the racks, or both racks, as the case may be, is en¬ abled by the curved or arc-shaped longitudinal formation of the teeth N of the racks and the teeth P of the traction wheel, it being noticed that as the wheel may tilt on the tread por¬ tion, the tooth flanges will simply shift by the wheel rocking on said tread as a pivot, and the intermeshing teeth changing their engaging position correspondingly and without becoming disengaged. In Figure 5, I have provided another arrangement for overcoming any tendency of accumulations to pack between the teeth of the racks, the result being accomplished, in this instance, by forming the racks in a transverse downwardly diverging relation, so that at opposite sides of the tread por¬ tion, the racks incline outwardly and downwardly, to the end that any material falling in the spaces between the teeth may work outwardly and fall at the sides of the rail. These inclined portions of the racks are illustrated at R. In figure 6, I show still another formation which would be useful in keeping the teeth of the racks in a clear or clean condition. This form embraces a base S, having a centrally disposed upwardly projecting web T, on which the tread U is formed, and at points intermediate of the securing flanges 30 W of the base portion and the web T, I form integrally with the base, upwardly and inwardly extended ledges X having horizontally disposed teeth Y, constituting the racks adapted to engage the gear-peripheries of the traction wheels. By this arrangement, ample spazes Z are left below the racks and and between the base and web to permit any material tending to clog the teeth to fall thereinto. The particular type of structure also presents an arrangement which may be easily cleared of accumulations by the introduction of any suitable implement, adapted to that purpose, through the slots Z between the tread U and the racks. In figure 4, 1 have illustrated at 5, a portion of a smooth rail devoid of the racks, occupying an approximately hori¬ zontal plane, and running into an inclined rail portion at 6, provided with the racks. While I have herein disclosed several convenient embodi¬ ments of my invention, it will be apparent that said inven¬ tion is capable of embodiment in still other forms and de¬ vices, all as will appeal to persons skilled in the art to which this invention pertains. I claim: 1.

SPECIFICATIONS AND CLAIMS. This invention relates to a structure adapted to primarily constitute a continuous, integral and rigid roadway and trac¬ tion way, capable of being used on the surface, on bridges, overhead, under water and under ground, in keeping with the topographical conditions and requirements surrounding any particular service for which the same is needed or use¬ ful, said service at times possibly requiring all of the fore¬ going uses in combination and at other times separately. The invention comprehends as features ancillary to the main object above stated, the formation of the road or trac¬ tion ways of suitable frames coupled together and strongly reinforced by means of braces associated to render the com¬ pleted structure as compact as possible, and said braces sub¬ dividing the frames into relatively small spaces adjacent to the relatively large road or traction ways, adapted to be utilized for many and various purposes, as will hereinafter more fully appear. The invention further has for its object the provision of a structure which will be simple, and relatively inexpensive, so that its field of service is practically unlimited, the same being capable of use not only after the fashion of ordinary elevated systems, bridges, subways and tunnels, but may also be employed as roadways through farming and coun¬ try districts without seriously impairing the property above which the same may be constructed, it simply being required that suitable supports attached to the structure and form¬ ing parts thereof or provided and erected separately, rela¬ tively widely associated, be used to sustain the weight of the structure at a suitable distance above the ground, and these supports being relatively widely associated, the same may cross farms and the like without serious inconvenience, which would overcome to a large extent, the usual difficul¬ ties in securing rights of way. Similarly, the structure may be installed either in lieu of or supplemental to a natural or existing country road, on the one hand by laying the struc¬ ture on the road surface or on the other hand supporting the structure thereabove without seriously obstructing the normal road. 34 It is another purpose of the present invention to provide a structure, the parts of which shall be of standard metal or other formations fashioned to be expeditiously assembled, and correspondingly maintained in serviceable condition at comparatively cheap cost. In that embodiment of the invention employed to cross over streams, topographical depressions, and other elevated situations, the same may be of a single span over narrow waterways or hazardous land depressions, in which connec¬ tion it is of a type capable of being self-sustaining when rest¬ ing and anchored at opposite ends upon suitable embank¬ ments, or the same may be formed in duplicate spans of con¬ tinuous arrangement to overhang wide waters or valleys when partially supported intermediate of the terminals, af¬ ter the accepted manner of bridge engineering; and inter¬ mediate the piers or bank supports, towers may be provided and between the towers the vertical parts of the structure may be continued downward until they reach and rest upon suitable fixed surface supports. The preferred embodiment of my invention, when availed of for any of the various purposes to which I have alluded, comprises the formation of the structure of a plurality of open metal or other frames, reinforced and partly formed of transversely disposed triangular portions to impart to the frame the undeniable strength flowing from such special shape, and the frames being strongly braced and tied to¬ gether through the medium of side brace rods arranged for example, in criss-cross fashion, or similar brace rods, where desired, also uniting the upper portions of the frames to¬ gether by longitudinal sills or bars rigidly secured to the various frames, and in the case of an elevated or bridge structure, the bottom portions of the same being additionally braced by rods or beams constituting tension members there- below, associated with suitable interposed struts therefor, bearing in line with the base members of the triangular por¬ tions previously mentioned, to the end that the supporting strains are distributed from the bottom brace rods or ten¬ sion members upwardly through the struts over the triangu¬ lar frame aligned, with the struts, and around the frame¬ work, as will later on clearly appear. Heretofore I have referred to the sub-division of the in¬ terior of the main frames into small ways or spaces border¬ ing the main road or traction ways, and reverting to that matter, it may be here observed that such spaces are con¬ veniently formed intermediate of the upwardly converging triangular frame members, and the side members of the main (preferably rectangular) frames, and within the crowns or apex portions of the triangular frame members. These spaces may be devoted to roadways for slow-moving, and rapidly-moving vehicles, respectively; and suitable foot paths 35 or ways for pedestrians. They, or similar spaces (provided with floors and enclosing walls or partitions if desired), may be utilized as ways or conduits to receive conductors for electric lighting, telegraph, telephone, water, gas or power transmission; pneumatic or other dispatch tubes, or minia¬ ture automatically controlled conveyors,—traction or other¬ wise propelled,—for transporting merchandise and mail and express packages from place to place without the necessity of attendants or manual control. Other uses may be resorted to, but those here mentioned will suffice in imparting the understanding of the wise sphere of usefulness attending these minor passageways, performing the useful function in my construction, and overcoming the great waste of space and expense incident to the present non-use of equivalent space. It will be understood, however, that the provision of these subordinate features of my invention is optional, and will de¬ pend largely upon the intended uses for which the structure may be designed, and the size thereof. The improved details in the construction and arrangement of parts of a structure made in keeping with my invention, and capable of accomplishing the desired results to which I have'made reference, will be apparent from the specific de¬ scription hereinafter contained, when read in connection with the accompanying drawings forming part hereof, and wherein preferred embodiments of the invention are illustrated. In the drawings: Figure 1 is an end view, partly in section of an elevated struc¬ ture. Fig 2 is a side elevation of the same employed as a bridge. Fig. 3 is a plan view, in single formation, of the structure duplicated to present the suggested double formation of Fig. 1. Fig. 4 is a side elevation of a section of an elevated struc¬ ture adapted to be supported from the ground or street. Fig. 5 is a side view, partly in section of a subway or tun¬ nel, and, Fig. 6 is a sectional view through Fig. 5. Referring more specifically to the drawings wherein the same reference characters designate like parts in the several series of views, and first with relation to Figures 1, 2, and 3, A represents a series of frames formed of metal bars, or com¬ binations of metal bars and wooden members, suitably joined and conveniently of rectangular outlines, the same being spaced suitable distances apart, in keeping with the length of structure desired, these frames being in either single or double formation, as will be clearly understood from a mere inspection of Figures 1 and 3 of the drawings, the lines of division between the double frames being constituted by vertical bars B; the purpose of a single frame, when used 36 being in keeping with a single stretch of road, and the double frame in keeping with a double road serving as outgoing and return portions. The frames are connected together longitudinally thereof by base bars C, top bars D, and sills C', and the sides are re¬ inforced, and the various frames further rigidly united and braced by brace rods E arranged in criss-cross fashion as illustrated; and usually the same criss-cross arrangement of brace rods will be employed to connect across the top of the structure with the opposite longitudinal members D thereof, as indicated at F. -The upper members of the frames A also constitute transverse braces D'. The sills C. to which I have just referred are arranged longitudinally of the structure and are firmly attached to the cross members of the frame on which the same rest, as clearly indicated in Figures 1 and 6. These sills give added strength to the structure, assist in maintaining the frame members in their proper separated relation, and owing to the rigidity thereof will be found useful as supports for rails, in which connection, that is when the rails are securely fas¬ tened to the sills, both the sills and rails as combined ele¬ ments will still further strengthen the completed device. The sills may be of any suitable material, for example, wooden parts or sectional steel jacketed together so as to make the same continuous, but it is unnecessary in this case to disclose the specific construction of the sills or the connecting devices between the sections thereof. The foregoing arrangement provides an unbroken enclosed and unyielding framework capable of bearing the supporting strains to which the same is to be subjected. The frames are still further strengthened laterally by inter¬ mediate cross bars or plates G fastened to the upright por¬ tions of the rectangular frames and extending through either a single frame when used alone, or entirely through both frames when used in the double formation. The main road or traction ways are represented at H and J. These ways are bordered by rectangular frames strongly re¬ inforced though the medium of conveging bars K extending from the lower outer corners of the frames upwardly to a point of juncture centrally of the top bars of the frame, this arrangement of the bars K with the base bars L of the frames constituting triangles, the characteristics of which are pecu¬ liarly appropriate in the combination, in which the strength of the triangle and the distribution of the forces and strains throughout the same will serve to maintain the structure in rigid and permanent operative condition. The base bars L operate in conjunction with the cross rods G, and top trans- vers bars D' to tie the side members of the frame and ren¬ der the same as rigid as necessary,—other and as many base bars, either as part of or separate from the triangles being 37 39 utilized wherever desired, the same being connected in an obvious manner to the longitudinal bars C of the frame and serving as adequate supports for those parts of the sill C located between the triangles. The cross-brace rods G are rigidly attached to the up¬ wardly converging side members K of the triangles, and these brace rods are intended to serve another function, namely, as supports for a suitable road-bed M serviceable for slow-moving and rapidly-moving vehicles respectively, the necessity for special ways for which in elevated and bridge structures has long been recognized. Below the roadways B and within the somewhat narrower spaces between the up¬ right members of the rectangular frame A and the inclined members of the triangles K, I mount foot paths or ways M for pedestrians. However, any or all of the spaces desig¬ nated at 7, 8, 9, 10, 11, 12, 13, 14, IS, 16, 17 and 18, between the side members of the main frames and the inclined side members of the triangular portions, as well as the spaces 19 and 20 beneath the apeces of the triangular portions may be utilized for any of the purposes herein-before outlined or analogous purposes, as may be found expedient. The opposite ends of the structure upon suitable concrete foundations or embankments represented in a general way at O at the opposite sides of the space to be spanned by the bridge, and the bridge is aditionally strengthened and an¬ chored in place by cables P passing around the upper por¬ tion of the bridge structure,—preferably on bearings near the upper points of the triangles,—and other cables Q passing below the bridge structure conveniently in grooves therefor formed in the bottoms of the longitudinal base bars C, suit¬ able anchoring means, as indicated at R, being embedded in the concrete or other foundation. S represents supporting bars extending downwardly below the central portion of the bridge and extending to the em¬ bankments to constitute the tension members of the struc¬ ture, said tension members being of any desired number and being sustained in position by traces or struts T extending therefrom to the base portions L of the triangles, so that the supporting strains are carried from the tension members S in a direct line upwardly to the top of the bridge through and around the triangular frame portions, this desirable result being accomplished by the vertical alignment of the triangu¬ lar frame portions with the struts just defined. In lieu of or in addition to the struts T above defined, it will be clear that I may carry down the vertical members of the frame work to constitute supports T' extending to the base of waterways or to suitable fixed supporting surfaces where the structure is used as an elevated roadway, said vertical extension which may be properly designated supporting standards being represented by dotted lines in Fig 2. 40 Assuming the ways H and J to be approximately level with the surfaces from which the bridge leads, it is desirable to provide steps U leading to the foot paths N, at the opposite ends of the bridge, and gradually inclined approaches U ex¬ tending from the ground surface upwardly to the road por¬ tions M of the bridge. While in Figure 2 I have shown the double formation of the bridge, for the sake of economy of space, I have illus¬ trated in Figure 3, but a single width frame, it being under¬ stood that in the double construction of the instance now be¬ ing particularly defined, the showing of Figure 3 is merely duplicated. From the above description, it will be appreciated by per¬ sons skilled in this art that in a practical, simple, inexpensive manner, I have furnished a structure capable of service in many situations and under varying conditions, one that may be quickly assembled or taken apart. It may, as clearly illus¬ trated, be used as a bridge alone or as a continuation of other systems; it may be satisfactorily employed as a road or trac¬ tion way in traversing routes wherein the structure may rest directly, entirely or partially, upon the ground, or entirely or partially underground or in water when suitably incased, as will presently appear. Instancing the use of the invention in an overhead or com¬ monly styled elevated system, I refer to Figure 4 wherein the framework, with slight modification, is illustrated at 21, the same being supported in proper raised position with refer¬ ence to the ground or street surface 22 by suitable supporting standards 23 disposed in vertical line with the triangular por¬ tions 24 of the framework, the standards being suitably braced in any convenient manner, as by cross rods 25. The modification in this frame work to which I have just referred consists in bringing the triangular portions in closer relation, so that the adjacent inclined side members 24 are overlapped and secured together as at 25, to present the advantage of the additional strength to be derived therefrom, the vertical di¬ vision bars B' in this instance passing through the points or juncture of the cross triangular members, as clearly seen in figure 6. An embedded or submerged tunnel or subway structure is illustrated in Figure 5,—also in detail Figure 6,—from which it will be noted that the framework is encased in a suitable tube or hermetically sealed casing or conduit 26 formed in sections interfitting, as in 27, and riveted together at 28. It will be appreciated that a subway formed in this manner will be of great strength, by reason of the triangular supporting members, and this additional example will serve to empha¬ size the rather universal application of my invention to roads and ways of the usually recognized types. As clearly shown in Figure 5, the tube formation may rest upon the bottom of 41 waterways or the same may be entirely embedded, or par¬ tially embedded in the earth and partially exposed, or en¬ tirely raised from the ground, as may be found advantageous in pursuing a level course for my mechanical or artificial road or way across the base of submerged territory; it be¬ ing understood that when the tubular formation is supported in a submerged, but elevated position with reference to the bed of the waterway, the vertical portions of the frame mem¬ bers 21 are extended downwardly to suitable rigid resting points at said bed of the waterway, as indicated at 21', Fig. 5. Perhaps it will be found that in this last referred to em¬ bodiment of my invention, the various spaces formed within the framework may be best utilized for the ancillary purposes set forth in this specification, said spaces being denominated 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 and 40, the main ways being indicated at 41 and 42. It will be instantly appreciated that by my arrangement in addition to the provision of a continuous rigid and integral structure, I make use of and render valuable these various spaces, which have heretofore been entirely wasted, and the saving in cost as compared to the making of independent conduits, etc., is obviated. From the disclosures herein made, it will be obvious that 1 have presented a roadway which, owing to its various em¬ bodiments, will be capable of use to meet all conditions en¬ countered in the building of systems of the character to which the invention relates in that although the several embodi¬ ments which I have defined may be used individually where desired, they may also be used collectively in a single system, said system including in its course undulating land portions, elevated portions as at street crossings, or through populated districts, and over farms; underground or subway portions in cities or elsewhere, bridges over waterways or limited width, and tunnel portions through relatively wide waters, in which latter connection the varying surface configuration of the submerged bed or bottom of the waterway may be met in substantially the same manner as on land, and as sufficiently indicated in Fig. 5 to impart the general or underlying idea involved. While I have herein disclosed the preferred embodiment of my invention, it will be understood that the invention is still capable of embodiment in other forms and devices without departing from the spirit thereof, all as may be in keeping with the hereto appended claims.
