UNiT-En STATES WILLIAM H. TAYLOR,

PATENT FFIGE.

OF NEW YORK, N. Y.

. SPECIFICATION forming part of Letters Patent No. 284,776, dated September 11, 1883.

Application filed August 25. 1882. (No model.)

To all whom it may concern: 7

Be it known that I, VVILLIAM H. TAYLOR, of the city, county, and State of New York, have invented new and useful Improvements in Oarbureted-Hydrogen-Gas-Generating Apparatus, of which the following is a specification.

This invention pertains to certain improvements upon apparatus for making carburetedhydrogen. gas described in recent Letters Patent to me, dated April 11, 1882, in which the operation of charging the retorts or furnaces canbe alternated quickly, and thereby render the operation nearly continuous.

In the devices herein set forth various improvements are introduced, simplifying the construction and greatly facilitating the distribution of the air and the steam throughthe retorts or furnaces, and also properly introducing the hydrocarbon substances, as will hereinafter appear.

In the drawings, Figure 1 is an elevation of one end of the furnaces. Fig. 2 is a vertical section of Fig. 1 through c b. Fig. 3 is also a vertical section at a right angle to Fig. 2. Fig. 4 is a transverse section a short distance above the grates. Figs. 5 and 6 are also seetional views, and will be explained hereinafter.

Upon a suitable foundation as of masonry, (shown at A,) the outer shell or casing of the furnaces is located, being formed ofplates of metal, B, strengthened by ribs of angle-bars B, and this casing serves as a support for the doors, pipes, valves, &c. The bottom is covered with fire-brick, and the gas-generating chambers G and D are formed of fire-brick walls resting on the foundation, but leaving a space of a few inches all around and over the top, between the casing 13 and the brick-work, to be filled in with sand or granulated fire-brick, which forms a support for the wall, but perniits expansion and contraction without rupture.

The grates are shown at O and D, and between them is a hollow bridge-wall or two walls, C and DZ-built of fire-brick upon opposite sides of a metal plate, E, which extends from one side of the metal casing to the other, and is fastened by rivets and angle-bars, as shown in Fig. 4 at E, and said plate extends nearly or quite to the height of these two walls, as seen in Fig. 3; but a space is left besand or some similar substance, as is done around the exterior walls, for a supporting agent, and then a cap, as at F, is fitted upon the top of the walls and over the plate, as seen in Fig. 3.

The air-pipes G for blast are placed in the lower outer corners of the ash-pits H, and they extend the entire length of the grates, and are provided with holes of increasing size from the end where the air enters to the back end, as shown in Fig. 2, for the purpose of giving as much air at the back as the front, or to equally distribute it along the entire length of the grate. The exterior ends of these pipes lead up to a common inlet-connection at G, which connects to afan. (Nothere shown.) Upon opposite sides of said inlet are cut-off valves G and G, attached to a lever, G, pivoted to the'casing of the furnace centrally between the valves, so that when the lever is moved to close one valve 'it opens the other and cuts off the blast alternatelyfrom under the grates.

The ash-pits H or chambers below the grates are provided with openings at one end for the removal of the ashes, and said openings are closed by covers, as at H, andbinding clamps and screws H to form gas-tight joints to the chambers, as these chambers or ash-pits also serve as conduits for the gas, after it is carbureted, to pass to the pipes K and K, which also serve as smoke-fines at each alternate operation, as alreadyexplained in my former patent. These pipes K and K lead to a common pipe, K at the top, which leads to the purifiers, (not shown but between these two pipes is placed a damper-valve at L, which opens to a smoke-flue to carry off the smoke from the fuel, but which is closed when the steam is turned on to form the gas. damper-valve L has its sides made flaring to .fit into a corresponding seat at L, and to the back of the valve is attached the opening-lever L pivoted at L so that it may be operated by a chain or rod extending down to a convenient point for the attendant to reach it. The damper may also have a counterbalancingweight at M, to assist in holding the valve closed against the pressure of the gas when it is passing.

Instead of issuing the steam into the ash pits through a single nozzle or pipe, as in my tween the plate and the walls to be filled with T This previous patent, for each grate, Ii'ntroduce, transversely, pipes, as at N, to issue the steam from the upper portion of the pipes in sprays forming nearly right angles with each other, as indicated by the arrows at N, Fig, 6, so

that the steam is thoroughly distributed and directly underneath the mass of coal as soon as admitted. Said pipes are connected to a common leading-pipe, O, which brings steam from the boiler. (See Fig. 5.) r

rThe carbureting substances are introduced through the nozzles at P, P, and 1?, which are placed in rows at different heights, as shown in Figs. 2 and 3, and they are connected to a common reservoir by a leading-pipe at R, which is furnished with cocks R between the rows, the object being to let in the hydrocarbon at different times in the generating-chamberas, for example, if the masses of coal should happen to be in a very highly-ignited condition when the steam is first admitted, and the hydrocarbon were let in at the upper row of nozzles, it might be charred before it could pass through the second mass of coal; hence by letting in the hydrocarbon at a lower point it will not have so far to travel through the incandescent coal. The pipes that conduct oil the smoke are provided with cut-oif slides at S and T, operated by a common lever, WV, in the same manner as the air-valves, so that when one is closed the other is opened.

It will be observed that all these pipes and valves and operating devices are mounted upon and supported by the metalcasing, so that the fire-brick work merely constitutes a lining, and is not required to support any of the metal-work; hence it will not be disturbed by expansion and contraction, as is so often the case in such apparatus.

Having thus described the several devices, I desire to claim- 1. A double-chambered gas-generating furnace provided with two grates and two ash- Y forth.

2. A double-chambered gas-generating furnace having two grates and ash-pits, and airinlet or blast pipes located in recesses in the extreme lower corners of the ash-pits and out of the way of the descending ashes, and provided with numerous perforations for distributing the air to various portions of the grates, as hereinbefore set forth.

, 3. In a carbureted-hydrogengas apparatus,

the combination of a gas-generating chamber having two or more sets of oil-inlet nozzles entering therein, through the outer wall thereof, at different heights, with a grate arranged below the oil-inlet nozzles,.and steam and air inlet pipes located beneath the grate, as and for the purpose herein set forth.

4. The combination of the vertical smoke and gas flues K K, having the connected valves S T, and the upper gas-escape pipe, K provided with a smoke-flue and damper-valve, L, with the double-chambered gasgen eratin g furnace, substantially as and for the purpose herein set forth.

In witness whereof I have hereunto subscribed my name and afliXed my seal in the presence of two subscribing witnesses.
