APPARATUS FOR GENERATING ILLUMINATING WATER-GAS.

SPECIFICATION forming part of Letters Patent No. 443,951, dated December 30, 1890.

Application filed April 24, 1886. Renewed May 27, 1889. Again renewed August 21, 1890. Serial No. 362,781. (No model.)

To all whom it may concern:

Be it known that 1, JOHN D. AV'ERELL, a citizen of the United States of America, and aresident of the city of Brooklyn, in the county of Kings andState of New York,have invented certain new and useful Improvements in Apparatus for Generating Illuminating ater- Gas, of which the following is a specification.

This invention relates to a combination, in

apparatus for generating illuminating watergas, with a cupola having two coal-chambers provided with grate, ash-pit, coal-inlets, gasoutlets, and steam-nozzles, of a central partition between said chambers with vertical oil- [5 retorts and communicating fixing-chambers with said retorts and coal-chambers and gasoutlets. By this means powerful oil-gas generation is carried on.

In the drawings annexed, Figure 1 represents a vertical longitudinal section of a generator with myimprovement. Fig. 2 is a transverse section at the fixing-chamber of the same. Fig. 3 is a plan View of the grates. H

A represents the outer metal casing of the 2 5 cupola, which is constructed with two rectangular coal-chambers B B and with a central vertical partition 0 between them.

Below each coal-chamber is arranged an ash-pit D, and over the latter a grate E. Each 0 ash-pit is provided with a proper seal-door F to remove the ashes and with an air-passage G, through which the blast is admitted.

Above each coal-chamber is made a fixingchaniber H, which communicates with the for- 5 mer chamber by means of a large central opening I in the arched top of the latter chamber. In the top of each fixing-chamber is provided the coal-inlet J over the opening I, and said inlet is closed by a proper gas-tight cap K, and a gas-outlet L is provided in each chamber H, which outlets from both chambers co nnect and deliver into the main pipe M.

In the partition 0 is or are employed one or more vertical central flatoil-retorts N, which have an opening 0 into each chamber II to pass the oil-gas from said retort in the fixingchambers, into which the gases from the coalchambers enter by the openings 1.

The sides and top of the coal-chambers are made with thick fire-brick lining, in which are employed the steam superheating-pipes I, terminating with nozzles Q in the ash-pit un der the grate for charging superheated steam into said chambers B into the incandescent coal for decomposition and generation of the hydrogen gas. The ash-pits and fixing-chambers are lined less thick. The retorts are still less thickly lined with fire-proof tile or brick, which at portions may be left off to expose small portions of the retorts to high heat. Said retorts have each on its top a proper movable cover, in which one or more oil-nozzles S are secured, and the oil is conducted to said nozzles by the oil-supply pipes R, which have suitable regulating-cocks. 6 5

The grates are constructed with rows of single half-way lateral bars a, placed at semierected position, meeting centrally in the coalchamber, and resting with their inner erected ends against one another upon alternate pro jecting lugs a formed upon them, as shown. The bottom ends of each row are supported upon a rock-shaft I? along the lining in suitable bearings d. Said rock-shafts have each an upward lip on the side toward the lining to stop the grate-bars from spreading into the lining, and each shaft has a shank protruding through the side of the cupola, which shank is guided in a stuffing-box attached to the shell of the cupola, and the outer end beyond the stufling-box is made square, suitable to apply a lever on it for rocking the shaft, and thereby vibrating the grate-bars and causing a raking of the coal. The retorts may have vertical partitions within them connecting the spaces between them at the lower portion of the retort. The oil may be introduced in a solid stream or in a fused stream and enter in the whole space or only in a partitioned compartment of the space to distrib: o ute to the passage connecting a secondary compartment, from which the gases may flow to further compartments or directly into the fixing-chamber. Said retorts, as shown, are

made of metal, and their bottom ends connect 5 their hollow space by the passage 2 from one to the other, so that the oil introduced at the top end of the one retort and not vaporized at the openings 0 drops lower down and be- Said vapors of the I00 comes vaporized below.

oil on arriving at the bottom of-this retort pass through the opening .2 at the bottom into the next retort, and there pass upward until finally meeting said openings 0 of the secondary retort and pass into the fixing-chambers H.

I am aware that two coal-chambers with a common partition between and acommon fixing-chamber connected therewith have been used heretofore, and also that an annular coalchamber with a vertical central oil-retort has been used.

I claim- In an apparatus for generating illuminating water-gas, the combination of two separate vertical coal-chambers B B, means for alternately operating the same, a top fixingchamber H, connected with each and with a common gas-main, a vertical hollow partition C, separating said coal-chambers, vertical metal oil-retort-s in the same,'an oilsupply above one of said retorts, and a passage between said retorts below, as described, whereby the oil and vapor may pass from one to the other, oil-gas outlets 0, connecting said retorts with the fixing-chamber, and ash-pit, grate, and steam-pipe, with delivery-nozzle Q in each coal-chamber.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 12th day of April, 1886.

JOHN' D. AVERELL.
