IV FOREWORD HIS HANDBOOK of Building Ordinances of the City of St. Louis for the year 1917—18 presents an almost complete revision of the building code. It is published in *the interest of all Architects, Engineers and Contractors of the city and is distributed to them gratis. It depends on the advertising that appears on its pages for existence. The firms who advertise in this edition expect returns from their investment and we have prepared a classified list of our advertisers which may be found on pages 269 to 288. It is our endeavor to allow only good, reliable firms to advertise in the Handbook, and we take this opportunity of asking the Architects, Engineers and Con- tractors to consider those whose announcements appear in these pages, when in need of materials or when writing specifications. Thus lending your aid will make it possi- ble to maintain the high standard of the book prepared for your use. We welcome any suggestions from users of the Hand- book which might tend to advance its aim. We have endeavored to index and cross-index each section of the code matter and trust that this feature will prove espe- cially serviceable to those who are obliged to refer to its pages.

It shall not be obligatory upon the division of building and inspection to retain such plans and specifications in its custody for more than three months after the completion or occupation of any building. All plans presented for examination or filing shall be drawn on tracing cloth, or other material equally durable, to a scale in India or other indelible ink, or may be drawings reproduced by the sun print, or other process. The building line shall be indicated on the foundation plan, and the plan of each floor and all necessary eleva- tions and sectional drawings to fully and clearly demonstrate the character and construction of the proposed work shall be furnished, together with a plan of the lot upon which the building is to be built or altered, showing its proposed location on the lot, and the location of all other buildings, if any, upon such lot. The plat shall be drawn to a scale, and shall have written thereon the principal dimensions of the lot and buildings, and their location.

The specifications and plans shall be in duplicate, agree in every respect, and shall state the block and the lot number where the house is to be erected, and contain the name and address of the owner, architect and builder. Sec. 11. Approval of plans and .speciflcatidns on compliance with building code. If the matters mentioned in any applica- tion for a permit, or if the plans and specifications accompanying and illustrating the same indicate to the building commissioner that the work to be done is not in all respects in accordance with the provisions of this ordinance, he shall refuse to issue a permit until such applications, plans and specifications shall have been made to conform in every respect to the requirements hereof, and when such applications and plans and specifications conform thereto the build- ing commissioner shall issue a permit, and shall file said applica- tion, and shall apply to the plans and specifications his official stamp, which shall imply that the plans and specifications to which the same have been applied, comply with the terms of this ordinance. The one set of plans and specification so stamped shall then be returned to such applicant. Sec. 12. • Alterations of plans. No person other than the build- ing commissioner or his duly authorized agents shall erase, materially alter or modify any line, figures, or coloring con- tained upon any plans or specifications after the same have been stamped by the building commissioner or filed with him for refer- ence. If, during the progress of the execution of the work, it is de- sired to materially deviate in any manner affecting the construction or other necessary essentials of the building from the terms of the application, plans or specifications, notice of an intention to mate- rially alter or deviate therefrom, shall be filed in the division of building and inspection and the written assent of the building com- missioner shall first have been obtained before such alterations or deviations shall be made. Sec. 13. Revocation of i>emiits. If the work upon any building shall be conducted in violation of the provisions of this ordinance, as to the use or application of material or workmanship or by deviation from the approved plans and specifications or by a false statement as to any material part contained in or accompany- ing the application upon which any permit has been issued, it shall be the duty of the building commissioner to revoke the permit for such building operations. And it shall be unlawful after the revoca- tion of a permit for any person to proceed with such building opera- tion until said permit shall first have been reinstated or reissued by the division of building and inspection. Before a permit which has been revoked, for any of the causes hereinbefore mentioned shall be reinstated, the entire building and building site shall first have been placed in a condition corresponding with the requirements of this ordinance, and any work or material applied to the same, in viola- tion of the provisions of this ordinance, shall be removed from said building. The reinstating or reissuance of a permit shall be without cost to the owner, unless the cost of said building shall be found to have been materially increased over the amount stated in the application, in which case the fee shall be prorated as provided in section 9 of this ordinance. Sec. 14. Expiration of permits. No permit shall be of any force or effect after the expiration of one year from the date of its issuance. If, after a permit for the erection, enlargement or alteration of a building, retaining wall or fence wall, or for the repair or removal of any building, or for any other purpose author- ized by this ordinance, shall have been granted and the operation called for by said permit shall not have been begun within one year from the date thereof, or if such operations when begun, are not completed within one year next after the issuance of said permit, then said permit shall be void, and before such operations can be begun or completed a new permit shall be procured and the fee paid as required by this ordinance for the original permit. Sec. 15. Extension of permits. If it shall be found that the time called for in any permit for building operations will expire before the said building or buildings can be completed, the building commissioner shall have the power to extend the time called for in said permit, without extra cost or charge therefor; if from evidence he may obtain in regard to same (from the owner or architect thereof, or from the contractor for such building opera- tions), he shall deem it proper to do so. Sec. 16. Duty to notify building commissioner when ready for inspection. It shall be the duty of the owner or his duly authorized agent or builder to notify the building commissioner in writing whenever any building is ready for inspection.

Terra cotta facings on brick walls or piers may be used, without any increased thickness of walls, provided all such facings be backed up solid with brick or concrete, the brick or concrete to fill all the hollow spaces in the terra cotta in such a manner that the same shall be thoroughly incorporated with the wall. Where metal facings are used on brick walls no extra thickness of brick work shall be required. Ord. 29560. Sec. 70. Existing pai’ty walls may be used. Walls hei etofore built for or used as party walls, whose thickness at the time of their erection was in accordance with the requirements of the then existing ordinance, but which may not be in accordance with the requirements of this ordinance, may be used if in good condition, for the ordinary uses of party walls, provided the height of the same be not increased. R. C. 377. Sec. 71. Height may be increased. In case it is desired to increase the height of existing walls, which walls are less in thickness than the standard required under this ordinance, section 55, the same shall be done by a lining by brick work to form a combined thickness with the old wall of not less than four inches more than the thickness required for a standard wall cor- responding with the total height of the wall when so increased in height. The said lining shall be supported on proper foundations. However, no lining shall be less than nine (9) inches in thickness, and all linings shall be laid up in cement mortar and thoroughly anchored to the old brick walls with suitable wrought iron anchors placed two (2) feet apart and properly imbedded into the old walls in rows alternating vertically and horizontally with each other. The old walls must first be cleaned of plaster or other coatings. In place of a brick lining as above, a skeleton steel or iron frame may be erected against said old wall and be properly anchored to same. The strength of said steel or iron frame and its foundations shall be the same as called for in buildings of skeleton steel construction for walls of similar height, and such steel or iron frame shall be fire-proofed as provided in this ordinance. Where the brick walls of dwellings erected before the passage of this ordinance was found, upon inspection by the building com- missioner, to be sound and in good condition, and to be capable of sustaining safely an additional story, he may, at his discretion, issue a permit for the erection of such additional story of brick work, even though the walls of the existing building be of less thickness than that required by this ordinance. R. C. 37 8. Sec. 72. Walls not to be carried up in advance of others. No wall or walls of any building, other than a skeleton building, shall be carried up in advance of any other wall of said building, except in the following manner: in all cases where one or more walls are carried up in advance of other walls of the same building, suitable provisions shall be made to properly bond to- gether and anchor such walls every four (4) feet in their height by wrought iron tie anchors, not less than one and one-half (11^) inches by three-eighths (%) of an inch in size, and four (4) feet long.

And further provided that in no case shall the area of the block to which the load is transmitted be less than double the area of the beam or timber or other material transmitting the load.. Clause Eight. All walls, hereinbefore referred to in the preceding section of this ordinance, shall be constructed in the following manner: The blocks shall be set only in Portland cement mortar composed of not less than one part Portland cement to three parts clean, sharp river sand. This mortar may be tempered with one part lime paste to eight (8) parts of a mortar. Tile blocks shall be thoroughly bonded, one to another, both vertically and longi- tudinally, and all joints filled with mortar, and when tiles are set in the wall, the vertical web of one shall occur as nearly as practica- ble directly over the vertical web of the adjacent tile below. The blocks may be built with voids horizontal and with mortar joints between all blocks, or they may be built with voids vertical, pro- vided all horizontal bearings or joints are reinforced with metal fabric of from one-eighth (Vs) to one-half {^ 2 ) inch mesh, capable of holding the mortar. This fabric shall be one-half (i/^) inch less in width than the width of the wall of the course upon which it is applied and shall be double lapped at all corners. Such web shall be spread on each horizontal course of tile before the mortar is put on, and shall be completely covered with and imbedded in Portland cement mortar as the course of blocks upon it is being laid. No cutting of blocks will be allowed to admit pipes in bearing walls when pipes extend more than one-third (1-3) of the story in height. The metal fabric hereinbefore specified may be omitted in non- bearing or curtain walls, or .when the tile is laid in bearing walls with the voids horizontal. In all parts of the city, within the fire limits, no interior joists or woodwork shall be within four (4) inches of the outside of the exterior of the wall. Ord. 295G0. Sec. 70.

These drawings and calculation sheets shall be submitted to the building commissioner for approval, and no work shall be commenced until the drawings shall have been approved by him. Condition of sui-face of steel. The steel used for reinforcing con- crete shall have no paint upon it, but shall present only a clean or slightly raised surface to the concrete. All dirt, mud and other for- eign matter shall be removed. Cleaning steel. If the steel has more than a thin film of rust upon its surface it shall be cleaned before placing in the work. Proportion of concrete. The solid ingredients of the concrete shall be mixed by volume in one of the following proportions: (a) Not more than three (3) parts fine aggregate to one of cement. (b) Not more than two (2) parts of fine aggregate and four (4) parts of coarse aggregate to one of cement; but in all cases the fine aggregate shall be fifty (.5<») per cent of the coarse aggregate. Cnit measure of cement. In proportioning materials for concrete, one bag containing not less than ninety-three (9.3) pounds of cement, shall be considered one cubic foot. — 50 — Mixiii« concrete. ’ The ingredients of the concrete shall be so thoroughly mixed that the cement shall be uniformly distributed throughout the mass and that the resulting concrete will be homo- geneous. Wetness and placing of concrete. The concrete shall be mixed •>s wet as possible without causing a separation of the cement from the mixture, and shall be deposited in the work in such manner as not to cause the separation of mortar from coarse aggregate. Placing concrete. Concrete shall be placed in the forms as soon as practicable after mixing, and in no case shall concrete be used if more than one hour has elapsed since the addition of its water. It shall be deposited in horizontal layers not exceeding eight inches in thickness and thoroughly tamped with tampers of such form and material as the circumstances require. Placing steel. All reinforcing steel bars shall be wired and se- cured in place in such a manner that when concrete is placed in the forms all bars shall be in the exact position indicated on the draw- ings. Before any concrete is placed in the forms the contractor shall notify the building commissioner that the steel work is ready for inspection. Location of joints. Before the placing of concrete is suspended the joint to be formed shall be in such place and shall be made in such manner as will not injure the strength of the completed structure. Joining old and new work. Whenever fresh concrete joins con- crete that has set, the surface of the old concrete shall be rough- ened, cleaned and thoroughly slushed with a grout of neat cement and water. Freezing weather. No work shall be done in freezing weather, except when the influence of frost is entirely excluded. In the months of November, December, .January and February, the prog- ress of the work shall not exceed one story in twenty-one (21) days, if reinforced concrete cloumns are used in supporting such floors. Protection of structural parts. Until sufficient hardening of the concrete has occurred, the structural parts shall be protected against the effects of freezing, as well as against vibrations and loads. Protection of concrete from drying. When the concrete is ex- posed to a hot or dry atmosphere, special precautions shall be taken to prevent premature drying by keeping it moist for a period of at least twenty-four (2 4) hours after it has taken its initial set. This shall be done by a covering of wet sand, cinders, burlap, or by con- tinuous sprinkling, or by some other method equally effective, in the opinion of the building commissioner. Ileinoval of fonns during warm weather. If during the harden- ing period the temperature is continually above seventy (70) de- grees Fahrenheit, the side forms of concrete beams and the forms of floor slabs up to spans of eight feet shall not be removed before ^our days.

All columns shall have longitudinal steel members so arranged as to make the column capable of resist- ing flexure. These longitudinal members shall be stayed against buckling at points whose distance apart does not exceed twenty times the least lateral dimension of the longitudinal member, but in no case shall the maximum spacing exceed the diameter of the column. The combined area of cross section of these longitudinal members shall not be less than three-fourths {%) of one per cent of the area of the concrete used in proportioning the column, and the stays shall have a minimum diameter of seven thirty-secondths (7/32) of an inch. Hooped columns. If a concrete column is hooped with steel near its outer surface, either in the shape of circular hoops or of a helical cylinder, and if the minimum distance apart of the hoops, or the pitch of the helix does not exceed three inches, then the strength of such a column may be assumed to be the sum of the following three elements: One. The compressive resistance of the concrete when stressed not to exceed eight hundred (800) poundes per square inch for the concrete, enclosed by the hooping, the remainder being neglected. Two. The compressive resistance of the longitudinal steel rein- forcement shall not exceed twelve thousand (12,000) pounds per square inch. Three. The compressive resistance which would have been pro- duced by imaginary longitudinals stressed the same as the actual longitudinals; the volume of the imaginary longitudinals being taken at two and four-tenths (2.4) times the columns of the hooping. In computing the volume of the hooping it shall be assumed that the section of the hooping throughout is the same as its least section. If the hooping is spliced the splice shall develop the full strength of the least section of the hooping. Semi-hooped columns. In hooped columns where the pitch of the spiral is more than three inches, the following minimum unit stresses shall not be exceeded: On the concrete flve hundred (500) pounds per square inch; on the vertical steel seven thousand and flve hun- dred (7,500) pounds per square inch, and on the spiral a stress equal to that given in the previous requirements for hooped columns. But if the pitch of the spiral exceeds six (6) inches, the column shall be proportioned as required for ordinary reinforced concrete columns, and the strength of the spiral shall be disregarded. Ord. 29560. Sec. 97. Minimum covering of steel. The minimum covering of concrete over any portion of the reinforcing steel shall be as follows: For flat slabs not less than one inch. For beams, girders, ribs, etc., not less than one and one-half (ll^) inches. For columns not less than two inches. In computing the strength of columns, other than hooped col- umns, the outside, one inch around the entire column, shall be neglected. Sec. 98. Reinforced ccncrete girads to be carried by the soil. The load carried by the soil shall be the total dead load and an average live load of not less than ten (10) pounds per square foot of all the floor area of the building, when used as an office building, lodging or tenement house, and an average live load of not less than twenty (20) pounds per square foot of all the floor area, where such building is used for mercantile purposes; and an average load of not less than fifty per cent of the total live load, where such build- ing is used as a warehouse. Good solid, natural clay shall be deemed to safely sustain a load of not more than two and one-half ( 2 ^/^) tons to the superficial foot unless satisfactory tests are made as noted in section 107. The area of footing courses shall be sufficient to meet this requirement. Ord. 29560. Sec. 104. L/oads on floors and roofs. The minimum live loads which the floors of buildings shall be capable of sup- porting, when uniformly loaded over their entire surface, shall be: For stores, factories, commercial buildings and warehouses, one hundred and fifty (150) pounds per square foot; for office build- ings, on all floors above the first, sixty (60) pounds per square foot; for office buildings on the first floor, stairs, corridors, public halls, main floors of theaters, buildings used for light manufacturing, stables and garages, one hundred (100) pounds per square foot; for churches, schools and galleries of theaters, seventy-five (75) pounds per square foot; for dwellings, hospitals, hotels, lodging, apartment and tenement houses, fifty (50) pounds per square foot. —67— Collapsible Joist Form Company FINANCE BUILDING Kansas City, Mo. ■ CONCRETE ENGINEERS AND CONCRETE EORM CONTRACTORS Write for literature.

The building commissioner may require the owner or occupant of any building or portion thereof, to re-dis- tribute the load on any fioor or to lighten such load where he may deem the same to be necessary for the protection of life and prop- erty. No person shall place, or cause or permit to be placed, on any floor of any building any greater load than the safe load thereof, and the building commissioner may require the safe load to be estimated and ascertain as provided in section 107, of this ordinance. R. C. 457. Sec. 107 Strength of floors to be computed. In all manufactur- ing and commercial buildings, where heavy materials are kept or stored, or where heavy machinery is operated, it shall be the duty of the owner or occupant of such building to have the strength of the floors of such building, and their supports, com- puted by some competent person, who shall estimate the weights which may be safely sustained per square foot of floor in such build- ing, and to reduce such estimate in writing, stating the materials, sizes, distance apart and span of beams and girders, posts or columns supporting each floor in such building, and the correctness of such estimate shall be sworn to by the person making the same, and it shall thereupon be filed in the Division of Building and Inspection. But if the Building Commissioner shall have cause to doubt the correctness of said estimates, he is empowered to revise and correct the same, and for the purpose of such revision the officers and em- ployes of the Division of Building and Inspection may enter any building during business hours and clear so much of any floor or portion thereof as may be required to make necessary measurements and examinations. R. C. 458. Sec. 108. Notice to be posted on each floor. When the correct estimate of the weight that the floor in any manufac- turing or commercial building will safely sustain has been ascer- tained, as provided in section 107, of this ordinance, the building commissioner shall approve the same, and thereupon the owner or occupant of said building, or any portion thereof, shall post a copy of such approved estimate in a conspicuous place on each story of the building to which it relates.

Maximum allowable working pressure. The maximum allowable working pressure is that at which a boiler may be operated as determined by employing the factors of safety, stresses, and dimensions designated in this ordinance. Ord. 29523. — 198 — No boiler shall be operated at a higher pressure than the maxi- mum allowable working pressure except when the valve or valves are blowing, at which time the maximum allowable working pressure shall not be exceeded by more than six per cent. Wherever the term maximum allowable working pressure is used herein it refers to gage pressure, or the pressure above the atmo- sphere, in pounds per square inch. Par. 2. The maximum allowable working pressure on the shell of a boiler or drum shall be determined by the strength of the weakest course, computed from the thickness of the plate, the tensile strength stamped thereon, as provided for in Par. 2, section 22, the efficiency of the longitudinal joint, or of the ligament be- tween the tube holes in shell or drum (whichever is the least), the inside diameter of the course, and the factor of the safety. TS X t X E = maximum allowable working pressure, hi. per sq. in. RXFS where TS = ultimate tensile strength stamped on shell plates, as provided for in Par. 2, section 2, lb. per sq. in. t = minimum thickness of shell plates in weakest course, in. ^ E = efficiency of longitudinal joint or of ligaments between tube holes (whichever is the least). R = inside radius of the weakest course of the shell or drum, in. FS = factor of safety, or the ratio of the ultimate strength of the material to the allowable stress. For new constructions, FS in the above formula = 5. BOILER JOINTS. Par. 3. Efficiency of a joint. The efficiency of a joint is the ratio which the strength of the joint bears to the strength of the solid plate. In the case of a riveted joint this is determined by calculating the breaking strength of a unit section of the joint, con- sidering each possible mode of failure separa^tely, and dividing the lowest result by the breaking strength of the solid plate of a length equal to that of the section considered. Par. 4. The distance between the center lines of any two adjacent rows of rivets, or the “back pitch” measured at right angles to the direction of the joint, shall be at least twice the diame- ter of the rivets and shall also meet the following requirements: Where each rivet in the inner row comes midway between two rivets in the outer row, the sum of the two diagonal sec- tions of the plate between the inner rivet and the two outer rivets shall be at least 2 0 per cent greater than the section of the plate between the two rivets in the outer row. Where two rivets in the inner row come between two rivets in the outer row, the sum of the two diagonal sections of the plate between the two inner rivets and the two rivets in the outer row shall be at least 2 0 per cent greater than the differ- ence in the section of the plate between the rivets in the outer row and the two rivets in the inner row. Par. 5. On longitudinal joints, the distance from the centers of rivet holes to the edges of the plates, except rivet holes in the ends of butt straps, shall be not less than one and one-half times the diameter of the rivet holes. Par. Ha. Circumferential joints. The strength of circumferential joints of boilers, the heads of which are not stayed by tubes or through braces shall be at least 5 0 per cent that of the longitudinal joints of the same structure. —199— When 5 0 per cent or more of the load which would act on an un- stayed solid head of the same diameteT as the shell, is relieved by the effect of tubes or through stays, in consequence of the reduction of the area acted on by the pressure and the holding power of the tubes and stays, the strength of the circumferential joints in the shell shall be at least 3 5 per cent that of the longitudinal joints. Par. 6. When shell plates exceed 9/16 in. in thickness in horizon- tal return tubular boilers, the portion of the plates form- ing the laps of the circumferential joints, where exposed to the fire or products of combustion, shall be planed or milled down to V 2 in. in thickness. Par. 7. Welded joints. The ultimate tensile strength of a longi- tudinal joint which has been properly welded by the forg- ing process, shall be taken as 2 8,500 lb. per sq. in., with steel plates having a range in tensile strength of 47,000 to 55,000 lb. per sq. in. Par. 8. Longitudinal joints. The longitudinal joints of a shell or drum which exceeds 3 6 in. in diameter shall be of butt and double-strap construction. The longitudinal joints of a shell or drum which does not exceed 36 in. in diameter, may be of lap-riveted construction; but the maximum allowable working pressure shall not exceed 100 lb. per sq .in. Par. 9. The longitudinal joints of horizontal return tubular boil- ers shall be located above the fire-line of the setting. Par. 10. A horizontal return tubular boiler on which a longitudi- nal lap joint is permitted shall not have a course over 12 ft. in length. With butt and double-strap construction, longitudinal joints of any length may be used, provided the plates are tested transversely to the direction of rolling, which tests shall show the standards prescribed under the Specifications of Boiler Plate Steel. Par. 11. Butt straps and the ends of shell plates forming the longitudinal joints shall be rolled or formed by pressure, not blows, to the proper curvature. LIGAMENTS. Par. 12. Efficiency of ligament. When a shell or drum is drilled for tubes in a line parallel to the axis of the shell or drum, the efficiency of the ligament betw’een the tube holes shall be determined as follows: When the pitch of the tube holes on every row is equal, the for- mula is: 1) — d = efficiency of ligament P where p = pitch of tube holes, in. d = diameter of tube holes, in. When the pitch of the tube holes on any one row is unequal, the formula is: p — n d = efficiency of ligament P wh3re p = unit length of ligament, in. n = number of tube holes in length, p, d = diameter of tube holes, in. — 200 — P^r. 13. When a shell or drum is drilled for tube holes in a line diagonal with the axis of the shell or drum, the efficien- cy of the ligament between the tube holes shall be determined by the following methods and the lowest value used; 0.9 5 (p^ — (1) a = efficiency of ligament b = efficiency of ligament 1 > where p = diagonal pitch of tube holes, in. d = diameter of tube holes, in. p = longitudinal pitch of tube holes or distance between centers of tubes in a longitudinal row, in. The constant 0.9 5 in formula a applies, provided p^ divided by d is 1.5 or over. Par. 14. Domes. The longitudinal joint of a dome 2 4 in. or over in diameter shall be of butt and double-strap construc- tion, and its flange shall be double riveted to the boiler shell when the maximum allowable working pressure exceeds 100 lb. per sq. in. The longitudinal joint of a dome less than 24 in. in diameter may be of the lap type, and its flange may be single riveted to the boiler shell, provided the maximum allowable working pressure on such a dome is computed with a factor of safety of not less than 8. The dome may be located on the barrel or over the fire-box on traction, portable or stationary boilers ' of the locomotive type up to and including 4 8 in. barrel diameter. For larger barrel diameters the dome shall be placed on the barrel. DISHED HEADS. Par. 15. Convex heads. The thickness required in an unstayed dished head with the pressure on the concave side, when it is a segment of a sphere, shall be calculated by the following for- mula: 5.5XPXD t' = + % 2 XTS where t = thickness of plate, in. P = maximum allowable working pressure, lb. per sq. in. TS = tensile strength, lb. per sq. in. L/ = radius to which the head is dished, in. Where the radius is less than 80 per cent of the diameter of the shell or drum to which the head is attached the thickness shall be at least that found by the formula by making L equal to 80 per cent of the diameter of the shell or drum. Concave heads. Dished heads with the pressure on the convex side shall have a maximum allowable working pressure equal to 60 per cent of that for heads of the same dimensions with the pressure on the concave side. When a dished head has a manhole opening, the thickness as found by these Rules shall be increased by not less than % in. Par. 1C>. When dished heads are of a less thickness than called for by Par. 15, they shall be stayed as flat surfaces, no, allowance being made in such staying for the holding power due to, the spherical form. Par. 17. The corner radius of an unstayed dished head measured! on the concave side of the head shall not be less than, in. or more than 4 in. and within these limits shall be not les^, than 3 per cent of L in Par. 15. — 201 — Par. 18. A manhole opening in a dished head shall be flanged to a depth of not less than three times the thickness of the head measured from the outside. BRACED AND STAYED SURFACES. Par. 19. The maximum allowable working pressure for various thicknesses of braced and stayed flat plates and those which by these Rules required staying as flat surfaces with braces or stayholts of uniform diameter symmetrically spaced, shall be calcu- lated by the formula: t2 P = C X where p2 P = maximum allowable working pressure, Ih. per sq. in. t = thickness of plate in sixteenths of an inch p = maximum pitch measured between straight lines passing through the centers of the stayholts in the different rows, which lines may be horizontal, vertical or in- clined, in. C = 112 for stays screwed through plates not over 7/16 in. thick with ends riveted over C = 120 for stays screwed through plates over 7/16 in. thick with ends riveted over 0=135 for stays screwed through plates and fitted with single nuts outside of plate C = 175 for stays fitted with inside and outside nuts and outside washers where the diameter of washers is not less than 0.4p and thickness not less than t. If flat plates not less than % in. thick are strengthened with doubling plates securely riveted thereto and having a thickness of not less than 2/3 t, nor more than t, then the value of t in the formula shall be % of the combined thickness of the plates, and the values of C given above mayalso be increased 15 per cent. Par. 20. Stayholts. The ends of screwed stayholts shall be rivet- ed over or upset by equivalent process. The outside ends of such stayholts shall be drilled with a hole at least 3/16 in. diameter to a depth extending in. beyond the inside of the plates, except on boilers having a grate area not exceeding 15 sq. ft., where the drilling of the stayholts is optional. Par. 21. When channel irons or other members are securely riv- eted to the boiler heads for attaching through stays the transverse stress on such members shall not exceed 12,500 lb. per sq. in. In computing the stress, the section modulus of the member shall be used without addition for the strength of the plate. The spacing of the rivets over the supported surface shall be in con- formity with that specified for stayholts. Par. 22. The ends of stays fitted with nuts shall not be exposed to the direct radiant heat of the fire. Par. 2S. The maximum spacing between centers of rivets attach- ing the crowfeet of braces to the braced surface shall be determined by the formula in Par. 19, using 135 for value of i\ The maximum spacing between the inner surface of the shell and lines parallel to the surface of the shell passing through the centers of the rivets attaching the crowfeet of braces to the head, shall be determined by the formula in Par. 19, using 160 for the value of C. — 202 — TABLE 2.

The formula in Par. 19 was used in computing Table 2. Where values for screwed stays with ends riveted over are required for conditions not given in Table 2, they may be computed from the formula and used, provided the pitch does not exceed Sy 2 in. Par. 2o. The distance from the edge of a staybolt hole to a straight line tangent to the edges of the rivet holes may be substituted for p for staybolts adjacent to the riveted edges bounding a stayed surface. When the edge of a stayed plate is flanged, p shall be measured from the inner surface of the flange, at about the line of rivets to the edge of the staybolts or to the pro- jected edge of the staybolts. Par. 26. The distance between the edges of the staybolt holes may be substituted for p for staybolts adjacent to a furnace door or other boiler fitting, tube hole, handhole or other opening. Par. 27. In water leg boilers, the staybolts niay be spaced at greater distances between the rows than indicated in Table 2, provided the portions of the sheet which come between the rows of staybolts have the proper transverse strength to give a fac- tor of safety of. at least 5 at the maximum allowable working press- ure. Par. 28. The diameter of a screw stay shall be taken at the bot- tom of the thread, provided this is the least diameter. Par. 29.

Holes for screw stays shall be drilled full size or punched not to exceed i/4 in. less than full diameter of the hole for plates over 5/16 in. in thickness, and % in. less than the full diameter of the hole for plates not exceeding 5/16 in. in thickness, and then drilled or reamed to the full diameter. The holes shall be tapped fair and true, with a full thread. I*ar. J?l. The ends of steel stays upset for threading, shall be thoroughly annealed. — 203 — Par. 32. An internal cylindrical furnace which requires staying shall be stayed as a flat surface, as indicated in Table 2. Pai*. 33. Staying' segments of heads. A segment of a head shall be stayed by head to head, through, diagonal, crowfoot or gusset stays, except that a horizontal return tubular boiler may be stayed as provided in Pars. 47 to 51. Par. 34. Areas of segments of heads to be stayed. The area of a segment of a head to be stayed shall be the area en- closed by lines drawn 3 in. from the shell and 2 in. from the tubes. Par. 35. In water tube boilers, the tubes of which are connected to drum heads, the area to be stayed shall be taken as the total area of the head less a 5 in. annular ring, measured from the inner circumference of the drum shell. When such drum heads are 30 in. or less in diameter and the tube plate is stiffened by flanged ribs or gussets, no stays need be used if a hydrostatic test to destruction of boiler or unit section built in accordance with the construction, shows that the factor of safety is at least 5. Par. 36. In a Are tube boiler, stays shall be used in the tube sheets if the distances between the edges of the tube holes exceed the maximum -pitch of staybolts given in Table 2. That part of the tube sheet which comes between the tubes and the shell need not be stayed when the distance from the inside of the shell to the outer surface of the tubes does not exceed that given by the formula in Par. 19, using 160 for th value of C. Par. 37. The net area to be stayed in a segment of a head may be determined by the following formula: 4 (H— 5)2 W 1 2 R— 3) 1 0.608 = area to be stayed sq. in. 3 (H— 5) where H = distance from tubes to shell, in. R = radius of boiler head, in. Par. 38. When the portion of the head below the tubes in a hori- zontal return tubular boiler is provided with a manhole opening, the flange of which is formed from the solid plate and turned inward to a depth of not less than three times the thickness of the head, measured from the outside, the area to be stayed may be reduced by 100 sq. in. The surface around the manhole shall be supported by through stays with nuts inside and outside at the front head. TABLE 3.

When stay rods are screwed through the sheets and riveted over, they shall be supported at intervals not exceeding 6 ft. In boilers without manholes, stay rods over 6' ft. in length may be screwed through the sheets and fitted with nuts and washers on the outside. Par. 40. The maximum allowable stress per square inch net cross sectional area of stays and staybolts shall be as given in Table 3. The length of the stay between supports shall be measured from the inner faces of the stayed plates. The stresses are based on tension only. For computing stresses in diagonal stays, see Prs. 43 and 44. Par. 41. The allowable loads based on the net cross-sectional areas of staybolts with V-threads, are computed from the following formulae. The use of Whitworth threads with other pitches is permissible. The formula for the diameter of a staybolt at the bottom of a V-thread is: D — (P X 1.732) = d where D = diameter of staybolt over the threads, in. P = pitch of threads, in. d = diameter of staybolt at bottom of threads, in. 1.732 = a constant. When U. S. threads are used, the formula becomes D— (P X 1.732 X 0.75) = d Tables 4 and 5 give the allowable loads on net cross-sectional areas for staybolts with V-threads, having 12 and 10 threads per inch: TABLE 4.

Par. 47. Staying of upper segments of tube heads by steel angles. When the shell of a boiler does not exceed 3 6 in. in diameter and is designed for a maximum allowable working press- ure not exceeding 100 lbs. per sq. in., the segment of heads above the tubes may be stayed by steel angles as specified in Table 8, except that angles of equal thickness and greater depth of outstanding leg, or of greater thickness and the same depth of outstanding leg, may be substituted for those specified. The legs attached to the heads may vary in depth V 2 in. above or below the dimensions specified in Table 8. Par. 48. When this form of bracing is to be placed on a boiler, the diameter of which is intermediate to or below the diameters given in Table 8, the tubular values for the next higher diameter shall govern. Rivets of the same diameter as used in the longitudinal seams of the boiler shall be used to attach the angles to the head and to connect the outstanding legs. Par. 49. The rivets attaching angles to heads shall be spaced not over 4 in. apart. The centers of the end rivets shall be not over 3 in. from the ends of the angle. The rivets through the outstanding legs shall be spaced not over 8 in. apart; the centers of the end rivets shall be not more than 4 in. from the ends of the angles. The ends of the angles shall be considered those of the out- standing legs and the lengths shall be such that their ends overlap a circle 3 in. inside the inner surface of the shell. Par. 50. The distance from the center of the angles to the shell of the boiler shall not exceed the values given in Table 8, but in no case shall the leg attached to the head on the lower angle come closer than 2 in. to the top of the tubes. Par. 51. When segments are beyond the range 'specified in Table 8, the heads shall be braced or stayed in accordance with the requirements of this ordinance. Par. 52. Crown bars and girder stays. Crown bars and girder stays for tops of combustion chambers and back con- nections, or wherever used, shall be proportioned to conform to the following formula: where C X d2 X T Maximum allowable working pressure = (W— P) XDXAV W = extreme distance between supports, in. p = pitch of supporting bolts, in.

Upper combustion chambers or vertical sub- merged tubular boilers made in the shape of a frustum of a cone when not over 38 in. diameter at the large end, may be used without stays if figured by the rule for plain cylindrical furnaces (Par. 61), making D in the formula equal to the diameter at the large end. When over 38 in. in diameter, that portion over 30 in. in diameter shall be fully supported by staybolts or gussets to conform to the provisions for the staying of fiat surfaces. Par. 54. Stay tubes. When stay tubes are used in multitubular boilers to give support to the tube plates, the sectional area of such stay tubes may be determined as follows; (A— a) P Total section of stay tubes, sq. in. = T where A = area of that portion of the tube plate containing the tubes, sq. in. a = aggregate area of holes in the tube plate, sq. in. P = maximum allowable working pressure, Ib. per sq. in. T working tensile stress allowed in the tubes, not to exceed 7000 lbs, per sq. in. Par. 55. The pitch of stay tubes shall conform to the formula given in Par. 19, using the values of C as given in Table 9: TABLE 9.

The tubes shall project about 44 in. at each end and be slightly flared. Stay tubes when threaded shall not be less than 3/16 in. thick at bottom of thread; nuts on stay tubes are not^advised. For a nest of tubes € shall be taken as 140 and S as the mean pitch of stay tubes. For spaces between nests of tubes S shall be taken as the horizontal dis- tance from center to center of the bounding rows of tubes and C as given in Table 9. TUBE SHEETS OF COMBUSTION CHAMBERS. Par. 5G. The maximum allowable working pressure on a tube , sheet of a combustion chamber, where the crown sheet is not suspended from the shell of the boiler, shall be determined by the following formula; — 210 — p (D — d) TX 27,000 W X D where P = maximum allowable working pressure, lb. per sq. in. D = least horizontal distance between the tube centers, in. d = inside diameter of tubes, in. T = thickness of tube plate, in. W = distance from tube sheet to opposite combustion chamber sheet, in. Example: Required the working pressure of a tube sheet sup- porting a crown sheet braced by crown bars. Horizontal distance between centers, 4% in.; inside diameter of tubes, 2.7 8 2 in.; thick- ness of tube sheets, 11/lG in.; distance from tube sheet to opposite combustion chamber sheet, 3 4 % in., measured from outside of tube plate to outside of back plate; material, steel. Substituting and solving: (4.125—2.782 X 0.6875 X 27,000 P = = 176 lb. per sq. in. 34.25 X 4.125 Par. 57. Sling stays may be used in place of girders in all cases covered in Par. 56, provided, however, that when such sling stays are used, girders or screw stays of the same sec- tional area shall be used for securing the bottom of the combustion chamber to the boiler shell. Par. 58. When girders are dispensed with and the top and bottom of combustion chambers are secured by sling stays or braces, the sectional area of such stays shall conform with the re- quirements of rules for stays and stayed surfaces. Par. 59. Furnaces of vertical boilers. In a vertical fire-tube boiler the furnace length, for the purpose of calculating its strength and spacing staybolts over its surface, shall be meas- ured from the center of rivets in the bottom of the water-leg to the center of rivets in the flange of the lower tube sheet. Par. 60. When the longitudinal joint of the furnace sheet of a vertical fire-tube boiler is of lap-riveted construction and staybolted, a staybolt in each circular row shall be located near the longitudinal joint, as shown in Fig. 17. Par. 61. Plain circular furnaces.

In case either of the methods outlined in sections b or c of Par. 14 is employed, the safety valve capacities shall be taken at the maximum values given in Table 11 for spring loaded pop safety valves, or 0.66 times the maximum values given in Table 11, for lever safety valves. Par. 16. When additional valve capacity is required, any valves added shall conform to the requirements in sections 2, 3 and 4 of this ordinance. Par. 17. No valve of any description shall be placed between the safety valve and the boiler, nor on the discharge pipe between the safety valve and the atmosphere. When a discharge pipe is used, it shall be not less than the full size of the valve, and the -discharge pipe shall be fitted with an open drain to prevent water lodging in the upper part of the safety valve or in the pipe. If a muffler is used on a safety valve it shall have sufficient outlet area to prevent back pressure from interfering with the proper oper- ation and discharge capacity of the valve. The muffler plates or other devices shall be so constructed as to avoid any possibility of restriction of the steam passages due to deposit. When an elbow is placed on a safety valve discharge pipe it shall be located close to the safety valve outlet or the pipe shall be securely anchored and supported. All safety valve discharges shall be so located or piped as to be carried clear from running boards or working platforms used in controlling the main stop valves of boilers or steam headers.

ARCHITECTS ENGINEERS AND CONTRACTORS In preparation of plans and specifications for new buildings, do not fail to include gas piping, as sooner or later gas service is required in practi- cally all buildings. We will be pleased to send one of our Engineers free of charge, to consult with you and to furnish any information in regard to installation problems or proper appliances. It costs much less to install pipes during process of building than it does to introduce them, afterwards. THE LACLEDE GAS LIGHT COMPANY ELEVENTH AND OLIVE STREETS Main 48 oo Central 3800 — 260 — RULES AND REGULATIONS In Effect January 1, 1916 THE LACLEDE GAS LIGHT COMPANY Eleventh and Olive Streets The following rules have been approved by the Association of Master Plumbers of the City of St. Louis: All gas fitters are requested to inform customers moving from one location to another to apply in person at office of the Company, or in writing or by phone, and arrange to have gas supply shut off at old location and turned on at new address. By giving such notice the customer will be protected against any- one using gas in his name at the old location and from becoming responsible for gas used by former occupant of the new location. Plumber must not undertake to blowout house pipes until meter has been disconnected. INFORMATION FOR ARCHITECTS, BUILDERS AND PROPERTY' OWNERS. In preparing plans and specifications for piping new buildings, provision should be made for, at least, one illuminating opening in each room and basement. Failure to provide adequate piping has, in many instances, caused great expense to owners in running addi- tional lines after the building has been completed. Arrangements should be made with the Gas Company for installa- tion of service, location of meter, etc., as soon as plans for building are completed. This will prevent both annoyance and expense. When alterations are contemplated in any building, the Gas Com- pany should be notified as soon as the permit is taken out, so that arrangements can be made for properly taking care of the piping and gas meters. Interference with meter or its connection is positively prohibited. AVliere alterations are made in a building, any change necessi- tated in the location of the meters or services must be made at the expense of the customer or owner of the building. In case of doubt as to proper location of the meters or services consult the Gas Com- pany. Estimate of cost of changing location of meters or services will be furnished by Company on request. All piping should be inspected as soon as possible after work is completed, and before lathing the building. It should again be in- spected after completion of the building, and before fixtures are hung. When such inspections have been made by the Gas Company’s inspectors, and the material used and labor performed conforms to the standard established in the rules herein, the Gas Company will on request issue a certificate of the form shown herein on page 178. If the rules governing the sizes of pipe to be installed are not in any instance clearly understood, or if unusual conditions are met with, not covered by the rules, the Company should be consulted. — 261 — APPLICATION FOR INSPECTION.

RULES GOVERNING THE SIZE OF PIPING. In all houses and flats containing five rooms and under, the main run to the kitchen for fuel must not be less than %-inch in diameter. Houses and flats having more than five rooms and less than twelve rooms, the minimum size of the main run to the kitchen for fuel must be 1-inch. In residences having more than twelve rooms, the minimum size run to the kitchen for fuel must be li/4-inch. Cellar lines should be hung from the ceilings. In each case leave one full size opening in the kitchen for gas range, etc. In figuring up the number of openings to be supplied, use the fol- lowing relations: — 263 — Openings Outlets %-in. V 2 -in. %-in. 1 3 1 3 7 For large buildings, or where unusual conditions are met with, consult the Gas Company, All 'fuel openings must rise from below. Cellar lights may be taken off of either fuel or illuminating pipes, and need not be con- sidered in figuring size of pipes to be run in flats and residences. For one grate and one opening in kitchen, not less than %-inch pipe must be used. Where tank water heater is to be installed, 1-inch pipe must be used to the first opening. Three grates and one range may be taken off of 1-inch pipe. When more than three grates and kitchen opening are taken off of pipe, the minimum size must be li/4-inch pipe. Always leave a i/^-inch opening in bath-room and a %-inch opening in laundry. They need not be considered when counting the number of openings to deternLine the size of pipe. In determining size of riser in kitchen, bath and maid’s room, in openings need not be counted*. No more than one grate opening will be allowed off of ^-inch pipe. All water heaters should be provided with vent pipe connected to open flue. All instantaneous automatic water heaters, such as are ordinarily set in basement, must be provided with separate runs, and connected to riser. Size of runs to be as shown in following table: Heaters Having a Consumption per Hour Between Length of Run Size of Pipe Less than 200 Cu, ft Not over 75 feet 1 -in. 200 to 300 Cu. ft Not over 75 feet 1^-in. 300 to 400 Cu. ft Not over 7 5 feet 1^-in. 400 to 1000 Cu. ft Not over 7 5 feet 2 -in. 1000 to 1500 Cu. ft Not over 75 feet 2^-in. For all water heaters of this type the size of the horizontal run must in no case, be less than the size of the opening in the heater, and preferably should be one size larger. Openings for kitchen appliances must extend 3 inches above floor level, and be 2 inches clear of finished baseboard. Openings for fire- place appliances must not project more than 1-inch above the finished bottom of the fireplace, and must not be run closer than 6 inches from either of the finished sides or back of the fireplace. In flat buildings or apartment houses, where appliances, such as laundry stoves, dryers, etc., are installed for the joint use of tenants, run pipe from each meter location to laundry, and provide a header with a lock cock for each tenant. A substantial lock should be furnished with each lock cock and cock should be locked — closed — when gas is not in use. Fasten securely to each cock a metal tag with the number of flat plainly marked thereon. In installations of this character a Avariiipg tag should be posted in a conspicuous place in the laundry, giving full instructions as to how the installation is to be handled, and warning tenants to always shut off the gas and insert the lock in the lock cock when leaving the laundry, especially where tenant is vacating the premises. Own- ers should see that this rule is rigidly enforced. * In large buildings, where foundation walls are of unusual thick- ness, a way must be provided for service pipe to pass through walls when the same are being constructed. The preferable way would be to build a sleeve of iron or terra cotta pipe in the wall at the point where the service pipe is to enter the building. — 264 — Applications should he made to the Superintendent of Distribu- tion at the Gas Company’s Main Office to locate the point in the wall where the sleeve should be built in, so that when the service pipe is run it will pass through the opening provided for it. In this way the damaging of the foundation walls and an additional charge may be avoided. The risers in building must, in no case, be less than %-inch pipe, and must, in all cases, be run inside of inside partition, and must not extend lower than 1 inch below the ceiling of a finished base- ment, or 1 ^-inches below the bottom of the first fioor joists in the cellar. When locating a riser in any building, the meter location must be borne in mind. In no case will the meter be set where it is exposed to frost or dampness, extreme heat, or is liable to injury from any cause. The character of the building should always be taken into consid- eration when providing for meter locations. If the entire building is heated, the meters will be set on the front cellar wall. In stores where no provision is made for heating the basement, meter location should be provided within the store. Risers in stores must not end under deck or bulkhead of show win- dows, as meters will not' be set there. Meter locations should be provided so that both meter and con- nections are of easy access, in order that the index may be read. The stop cock should be so placed that gas may readily be turned on and off. In apartment buildings it is desirable to set meters in the base- ment or in a room provided for the purpose. If to be set on the different floors, locations should be provided so that they may be accessible without entering the apartments. The Company reserves the right to determine in all cases, tlie' location of the meters. When locations are provided that are not acceptable to the Company, the necessary changes in piping will have to be made at the owner’s expense before the meters are set. In apartment buildings all risers must be properly tagged with aluminum tags firmly fastened to riser, each tag so stamped as to indicate the location in apartments supplied. An economical arrangement would be to supply all apartments with one meter; one person being responsible for payment of bill, thus securing full benefit of the lower gas rates. The piping and fittings for the conveyance of gas within the walls of a building, after it has passed the meter and meter connections, may be put in by any competent gas fitter. In houses or buildings having no cellar, or where the conditions in the cellar are such as to make it an improper location in which to set meters, a meter location must be found in one of the rooms on the first floor, but in no case will a meter be set in a room used as a sleeping apartment. Meters should not be set in an unventilated closet or in any loca- tion where they are liable to sustain damage, as for instance, behind a door or in a coal bin. GAS ENGINES. Separate gas service and run for gas supply will be required where, in the judgment of the Gas Company, conditions demand such installations. Size of Engine 1 H. P 2 H. P 5 H. P i 10 H. P Size of Pipe %-inch 1 -inch 11/4 -inch IV^-inch —2*65— For gas engines using more than 2 50 cu. ft. per hour and less than 500 cu. ft. per hour, use no pipe less than 2 inches in diameter, where the length of the run is less than 60 feet. For gas engines using more than 500 cu. ft. per hour and less than 750 cu. ft. per hour, use no pipe less than 2i/^-inches in diameter, where the length of the run is less than 60 feet. For gas engines larger than the above, consult the Gas Company. It will be necessary to furnish a governing gas holder or some form of anti-fluctuator of sufficient size and suitable design to avoid all chance of causing a fiuctuation or variation in the gas pressures near where the gas engine is installed. It is advisable, before proceeding with the installation of a gas engine or piping for same, that consultation first be had with the Gas Company. IMPORTANT. Drops in double parlors, and large rooms in office buildings, must not be less than %-inch. Drops must not project more than 114 inches or less than %-inch below ceiling. The running line for stores must be full size to end of last open- ing. All drops to be 14-inch, except in show windows, where %-inch may be used. Risers for bracket lights should never be put in place until after the studding for partition is firmly secured, and must be rigidly sup- ported and fastened by straps to wooden cleats. All openings for wall brackets must be made with drop ells, and the wall outlet must project not more than %-inch, or less than %-inch, and be well fastened with straps. Fastening with nails will, in no case be allowed. When outlets are not in close proximity to studding, a notched wooden cross-piece must be securely fastened to studding to secure same. Bracket outlets may raise from below or drop from above. The drop must be securely fastened, and when located between the joist, a notched wooden cross-piece must be securely fastened to the joist to secure same. Fastening with nails, will in no case be allowed. Must be tin or iron straps. Pipes must be so run and covered as to be readily accessible. Do not run them at bottom of fioor beams which are to be lathed and plastered. They must be securely attached to the top of the beams, which should be cut out as little as possible. W'here pipes are paral- lel to beams, they must be supported by strips nailed between two beams. These strips must not be over 4 feet apart. All cutting of beams should be done as near as possible to the ends or supports of the beams. Pipes must not be laid beneath tiled or parquet fioors, under marble platforms or under hearthstones, where it can be avoided. Floor boards over pipes should be fastened down by screws, so that they can be readily removed. Cinder — Concrete or any corrosive material will not be permitted around pipes. When the walls are of masonry, they should be plugged and the straps fastened to the plugs. Always use fittings in making turns; do not bend pipe. Do not use unions in concealed work — use right-and-left couplings. Long runs of approximately horizontal pipe must be firmly supported at short intervals to prevent sagging. All horizontal outlet pipes must be taken from the sides or tops of running lines, never from below. -^ 266 ^ When pipes pass through masonry walls they must be encased, the gas pipe resting on the bottom of the casing pipe, with a. clearance of V 2 in. on top. The piping must be entirely free from traps and grade to riser. In no case will drips be allowed. Split pipes or fittings will not be accepted, even though skillfully cemented. All openings in building service must be equal to the size of the riser, which, in no case, must be less than 1-inch. The riser in any building must not be less than 48 inches from the floor, except by special permission from the Gas Company inspector. Where meters are to be set on wall, no riser must be higher than 9 feet from floor. Building services must be brought to point in building as desig- nated by Gas Company, and within 18 inches of wall or partition. In all cases where building service is used, provide header with an opening for each riser. Where risers are in groups, they must not be less than 10 inches apart, and service openings must not be less than 14 inches apart. In all cases where extensions are made, care must be taken to break pipe where the rule for size can be maintained, and in no case must extension be made from small pipes. Underground work by gas fitters between main and meter will not be allowed or accepted. Where line is extended underground, as for instance, to supply a garage, galvanized pipe must be used and pipe must be run in a straight line. Care must be taken that underground piping shall not be surrounded by any corrosive substance such as cinders, and should be drained to an accessible location. No underground pipes shall be laid having a diameter of less than one inch. Underground gas piping should be laid in separate trench from other conduit. To avoid complications, gas fitters should consult the Company before locating risers in corner buildings. Hotels, boarding house, restaurant and industrial installations, should be considered special and Gas Company should be consulted in connection therewith. The tables given are sufficient to cover almost any case that may arise, but it is advisable for architects, builders and others installing piping systems to confer with the Gas Company on all installations in large buildings. All tests will be made with an air pressure of 6 pounds to the square inch on a spring gauge, or 12 inches of mercury on a mercury gauge. Fixtures should be made to withstand an air pressure of 3 pounds to the square inch on a spring gauge, or 6 inches of mercury on a mercury gauge. They should be tested in place with a pressure of 8 inches of water. Pipe will not be tested until securely fastened in position and all outlets are provided with iron caps. All drops to be bent or offset. Double bracket strips will be counted as one opening if not more than 10 feet of pipe is used in the horizontal run to such bracket strips. The two openings off of such bracket strips will be counted as one outlet. A tee shall be installed at the bottom of every riser, located about 2 inches below the joist and left so as to be accessible for clean- ing pipes. — 267 — The cap shall be omitted from bottom of riser and all tests of piping shall be made from that point. But all outlets in the entire system of piping, with this exception, must be properly closed by the fitter, as the Gas Company will not supply caps or plugs for this purpose. The riser must be brought to within 6 feet of the location of the meter. This Company’s fitters are prohibited from doing any fitting work not ordered from the Company’s office. Inspectors are not expected to count the openings on building plans, but to inspect only the piping installed. In inspecting piping, the Company’s Inspectors are to notify the Master Plumber in charge of the building, in connection with any changes required in piping. This Company’s inspectors will state cause for rejecting piping by addressing a written communication to the Master Plumber. If defects are not remedied in four days after Company has notified Master Plumber, then the Company will take up the matter with the owner. Master Plumbers agree to Inform this Company, when ready to have piping tested, on postal cards to be furnished by the Company. OLD BOLDIXGS. The foregoing rules for new buildings are applicable for old buildings wherever practicable, but it will be permissible to connect fuel appliances to an opening on a pipe which comes from above, providing the size of piping is sufficiently large to supply the appli- ance. There should always be as a minimum a %-incli outlet left in the kitchen. CONNECTING APPLIANCES. Fitters are particularly requested to see that all gas-burning appliances are connected solid, wherever practicable, with iron pipe, but portable gas appliances may be connected with fiexible tubing and connections which have been approved by the Gas Company. THESE RULES *\RE vSCRJECT TO CILINGE. This Company reserves the right to alter, amend or revoke these rules, as may, from time to time, appear to be for the best interests of its patrons. All gas fitters’ rules heretofore issued by this Company are hereby revoked. Copies of these rules will be furnished on request at the office of the Company. — 268 — C LASS I F I E D LIST OF ADVERTISERS 'll n • E. o n SA O S > .. ^ VM 3 z S F- O t; o rn ADVERTISING (OUTDCMDR) CUSACK, THOMAS CO., St. Louis, 21st and Wash Streets Bmont.
