I PRESENT HEREWITH a sectional view of the Baokcjs Furnace, vith tlio side hrokon away so that its modo of oporation may be the more readily observed. The great claim for the Backus Furnace is that it assures perfect combustion, which includes in its train fcconomy of fuel, elimination of the smoke nuisance, a minimum of work for the fireman, and freedoii; from soot and cinders. The commonly accepted construction of a furnace is to place a orate under the boiler, throwing thereon soft coal for fuel, and closing the door. The process of slow combustion melts the coal, which runs down and closes the apertures of the grate. This excludes the air and renders combustion imperfect, for the want of sufficient oxygen. By* the introduction of a large volume of air the black- smith with his bellows o otains perfect combustion in his forge. In a contfagration where the free presence of oxygen inten; ifies the flames, brick walls are melted. Hence by the introduction of a sufficient amount of oxygen in the ordinary furnace perfect combustion may be obtained. This is accomplished by introducing air through large ducts or flues built in the brick work at each side of the fire box in front, and by substituting grate surface in place of tha ordinary or common door-sill, and by building a brick arch between the boiler and tire, — this arch abutting against the front and over the door, and extending into the furnace sufficient distance [depending on the length of the boiler], to heat the incoming air before it mixes or comes in contact with the escaping carbon or soot, and preventing the cold air meeting the boiler. The arch becomes intensely heated and causes the cases to ignite with the carbon, giving off a clean flame or perfect combustion at the inner end of the arch. The philosojyhy of this furnace in brief is, that by the air ducts at the front a large volume of air is admitted, which, passing over the fire and under the red hot arch, unites with the carbon and creatcg a perfectly clean flame. There ean thus be no deposit of soot in the flues or escape of smoke through the chi.imey for the reason that both soot and smoke are consumed under the boi er, and thus,instea.lof a nuisance, are utilized as Hame producers. By elongating and elevating the bridge wall the Hon.e is nm(h. to hug the boiler, and a small pit at the rear end receives what cinders may escape comimstiou. , ,. ■ i i.u • \ ^ This furnace, according to testimonial.), is recognized as the Jireman s friend, as there is less coal reciuired to perforn. a given amount of work, less a,shes to remove, and no soot m tlues. The company hold a testin.onial letter fron. Jas. H. Wade, Secretary and steward ot the University of Michigan, where nine of these furnaces are in operation, also from ( . H. «uhl, J J. BaLdev & Co Metcalf Bros, and others of Detroit, Michigan, and many others in ditlerent parts ot the country; all speaking in the most um.ualihed terms of praise of the device, ".so perfect in its working that nothing appears wanting." , . ^ . ^ n Any ordinary furnace can be recon.structed with this arch and air ducts at small expense. I have purchase.1 the right to con.struct and u,se this furnace for the Dominion of ( anada and am prepared to give instructions how to construct the same, and will guarantee results, and sell the rieht to others to build and u.so the furnace for an e(|uitable consideration.

[From the (JhtctKO V»Uj Tribune, December Mtli, 1NK7. | Looking^ at some Smoke Burners. Vcstenlay iiiorniiig CoiiiiiiisHioiier Thompson, C'aplaiii Diinliain, of the tUK company, Judge Van HlgghiH and representtttiveH of the prews, accompanied Mr. C. M. John- Hon to tlic Chicago Hurlington & Quincy yardH to sec his Mmokf-biirning.Ievice in operation on a Mwitdi engine in the railroad yards. Mr. .TolniHon lias simply tried to improve the Ilutcldn- Hon patent l)y forcing sleani tliroiigli several smaller jets than those used on the original patent, and that is the only l)erceplll)lo did'erence. While it will prevent much of the thick, hiack smoke, HO will the Hutchinson and the other half a thousand steam-jet, holair devices, hut it will nut consume any greater percentage than the others, and therefore is no hetter. It was given a thorough test yesterday. The llrei.ian threw coal in the furnace, and wlicn a thick volume of smoke began to roll irom the stack (he steam was turned (in, and in a very short lime the color of llic smoke was considerably whitened and cleared, but not to the extent that is desired or expected of a perfect smokeconsiiiner. C'ommlssUiner Thompson said it was no belter tluin many others, and, while intended as an improvement on Ifiitchinson's jtatent, he thought that it was doubtful if it is as good n device as many others now in use in this city. .Judge Van Iliggins, who has been making the smoke iiuestion a special study, had a very poor oj)inion of Mr. .lohn.son's invention, and thouglit it no bett;'r than matiy others now in use in Chicago. The device at the Xatiomvl Insurance Company's build- ing was examined at .Judge Iliggins' suggestion and was thought to be a good one of its icind— steam jet. A. Backus, another inventor, has placed one of his con- sumers in the furnace at Slack's grocery store, at the cor- ner of Wabash Avenue and Madison Street. In the after- noon a "Tribune" reporter, in company with Commissioner Thompson and the inventor, called to see it in operation. Mr. Hackus claims that by the introduction of a sufticient nmouiit of oxygon in the ordinary furnace, perfect combus- tioumaybe obtained. This, he says, is accomplished by the use of his device, which is simply the introduction of iiir through large dticts or Hues built in the brick work at each side and the building of a l)rick arch between the boiler and tire. This arch abuts against the front and over the door, and extends into the furnace a sutlicient distance to heat the incoming air before it mixes or conies in contact with the escaping carbon or soot, aiul prevents the cold air meeting the boiler. The ar'-l, l)ecomes in- teii'ely heated, and causes the gases with the carbon to ignitc.giving oflfa clear flame or perfect combustion at the inner end of the arch. The fireman at Slack's filled his furnace full of fine coal, which ordinarily throws ofl' smoke like a volcano, t)ut not the faintest show of Hmoke could be xeen coming from that chimney, and no one could tell there was a fire in the fur- nace. Oommissioner Thompson gave it his en- dorsement. I Fnuii tlie ClilcaKii n»lly News, Decemlwr 141 li, IHMT.I Testing a Smoke-Consumer. inspector Thompson an Interested Spectator at a Successful Exhibition. A successful trial of the Hackus smoke-conHumer was made yesterday afternoon at Slack's wholesale gnicery in the presence of .''inoke Inspector Thompson, Charles Slack and a " Daily News " rei)orler. A lire was built of Indiana block <'x>al slack, which usually makes a dense black smoke, and on top of this was thrown a barrel aiul a half of de- cayed apples and bananas, damp straw, and sweepings. An immediate rush was then made for the outside to see the smoke, but not enough was ijerceptible to discolor the cheek of a society liellc. Col, Thompson, w ith the pros- pect in view of hjsing his job, laughingly threatened to 'lanl the engineer up and tine him if he couldn't make ii smoke. This snK.ke-coiisume"' lias been in use twd weeks, and Mr, Sl.ack was much please<l with its workings, "I have good reason to believe it a success," he said, " I am in favor of c burner which will do away witli smoke without the aid of steam, Thii seems to doit satisfac- torily." "Itrieil my best to make it smoke," said Kngineer Adams, "and I can't do it." The principle of the furnace is simply that of perfect cond)ust ion through .1 plentiful 'supply of air. This is fur nislied by enlarging the grates, conducting air from the sides of tl;e furmice, ami decreasing the room in tlu' lire- box by means of a brick arcli. IFromtlieruDaclianMiiimfttclureiaiKlInilii-li-liil World. Dec. Ifith. 1HK7. | Mil. Mauk II. Irish, Toronto, has purchased tlie Can- adian patent right to the Hackus perfect condjuslion boiler furnace. The philosophy of ihis furnace is that l)y |)ro- perly arranged air ducts at the front of the furnace a large volume of air is a<linilled, which passes over the lire and under an arch constructed of lire brick, which becomes in tensely hoi. The inflow of air becomes heated to a high degree, and, uniting with the carbon of the fuel, creates ,i clean Hame. There is thus but little or no deiiosil of soot in the flues, or escape of smoke- uiu'onsumed carbon- from the chimney. There are no^v two of these Hackus furnaces in successful operation at the works of the Massey Manufacturing Co., and two in the Rossin House, one in (ieorge P. .Sharpe's Steam Laundry, York Street, Toronto, of which inspection is invited. Several others are aiwul being placed in estal)lishmenls in the city using large (luantities of fuel, regarding the success of which we will sjieak at another time.
