GAS-GENERATOR.

ESPECIFICATION forming part of Letters Patent No. 299,919, dated June 3, 1884.

Application filed October 22, 1833. (No model.)

SeX, in the Province of Ontario, Canada, gasmanufacturer, have invented certain new and useful Improvements in Gas-Generators, of which the following is a specification.

This invention relates to a generator in lo which gas for illuminating` or heating purposes is manufactured; and it consists of the improved construction and combination of parts of the same, as will behereinafter more fully described and claimed, reference being had to the accompanying drawings, wherein- Figure l is a side elevation of a gasgenerator embodying` my invention. Fig. 2 is a sectional view of same.

C designates a cupola, constructed of any 2O suitable size or shape, but it is preferably constructed in circular shape, and provided with a chamber, A, and grate-bars B. The

steam-pipe D and air-blast pipe E communi.

cate with andv discharge into the chamber A.

This discharge is governed by valves F E.

The air-blast pipe E is rst turned on, which introduces air to the chamber A, which air passes up through the grate-bars B into the furnace-generator G.

furnacegenerator G is filled with fuel to the height represented by the dotted line w; and this furnace-generator G is provided with a beveled conductor, G', projecting inside of the 3 5 brick-work of the furnace, as shown in Fig. 2

of annexed drawings, to conduct the spray of oil to the center of the fire, and thereby prevent it running down the sides of the brick-work of the furnace. This conductor G also conducts 4o the fuel to the center of the furnace, and thereby prevents it packing around the sides of the furnace. As the air passes up through the bed of fuel, it takes 'up and carries along with it the inflammable unconsumed gases aris- 15 ing from the imperfect combustion of the fuel,

which gases are heated and conducted fromv the generator G to the chamber H by the conducting-tube I. Into this chamber H another 'air-blast' pipe, E, discharges another volume 5o of air, which intermingles with the heated inl This air supports andv 3o causes increased combustion ofthe fuel. This flammable gases conducted thereto by thetube I. These intermingle, unite, and cause complete combustion of the whole` which superheats the brick-work H in the chamber H. This brick-work H is constructed in rows about two inches apart, and the rows of one layer are at right angles to the rows of the succeeding layer. j

L is a solid partition of fire-brick slabs, separating the chamber H from the furnacegenerator G. The airblast pipes E and E are then shut off, and the safety-valve door J is closed. The steam is then turned on and introduced into the chamber A through pipe D by opening valve F. It then passes up through the grate-bars and fuel. At the same time the petroleum-oil or other hydrocarbon is introduced into the furnacegenerator G (through oil-pipe O by opening valve F2) and vaporized. This vapor is then carried through the conducting-tube I, where the oil-gas and water-gas'or steam becomes thoroughly incorporated with one another'. This gas then passes into and through the superheatingchamber H and `brick-work H,where all these vapors are superheated, and thereby made into a fixed gas, which passes out through out` let-pipe K.

M is a door on the side of the cupola, above the furnace, through which the furnace is supplied with fuel; and M M are doors on the sides of and near the bottom of the cupola, for the purpose of removing ashes or clinkers from the furnace G or chamber A.

By using the dividinglpartition L the watergas and oil-gas are prevented from entering the superheating-chamber H separately, because if these two gases entered this chamber vH separately a portion of the oil-gas would burn, thereby requiring a larger quantity of 9o oil to produce a certain quality of gas.

N2 is a water-jacket on the outside of the metallic furnace-shell N, and is for the purpose of keeping the sides of the furnace-shell N cool, in order to protect and prevent the casing or shell N of the furnace from burning. The advantage of using the metallic shell N as a casing for the furnace is, that when using a nre-brick casing for the furnace the clinkers `unite with the brick-work, and on knocking IOO these elinkers off they take a portion of the l' The cupola C, provided with furnace-genbrick-work with them, which in a very short time destroys the brick-work of the furnace, all of which trouble is obvated by using,` the metallic shell N as a lining for the furnace G.

I? P are narrow strips of slabs secured in the cupola C and laid a short distance apart, for the purpose of supporting the brick-work II', at the same time permitting the free passage of the gases.

R is the fire-brick easing of the cupola, lined on the outside with a sheet-iron plate, S, to prevent the escape of any ofthe gases.

Having thus described my invention, I

claimerator G, beveled conductor G', and metallic casing N, water-j aeket N2, superheating-chamber'H, provided with brick-work H', conducting-tube I, and central partition, L, substantially as shown and described, and for the purpose specified. Y

In testimony whereof I affix my signature in the presence of the two undersigned witnesses. x
