JOHN ZELLWEGER, OF CHICAGO, ILLINOIS.

GAS-PRODUCER.

I SPECIFICATION forming part of Letters Patent No. 271,673, dated February 6, 1883.

(No model.)

To all 'whom it may concern Be it known that I, JOHN ZELLWEGER, of Chicago, inthe county ot' Cook and State ot' Illinois, have invented certain new and useful Improvements in Gras-Producers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to the construction of that part ot' gas-producers in which the cornbuston of the fuel takes place and in which the ashes and clinkers accumulate; and it has for its object to afford better facilities for cleaning the tire. Therefore the invention consi/sts in the devices and combinations of devices employed by me, as hereinafter described and specih'oally claimed.

1n the accompanying drawings, Figure l represents a longitudinal vertical section of a gas-producer having my improvements; Fig. 2, a front view and transverse vertical section of a double producer.

Like letters designate corresponding parts in both the figures. v

A denotes the coking-chamber5 B, the hearth or hearth-plate; C, the combustior1chau1 ber; D, the cooling-chamber or ash-pit underneath the hearth; a, a horizontal tlue above the hearth, leading frornthe combnst ion-chamber; b, a vertical ilue behind the hearth, leading from the due (t to the cooling-chamber; E, the bridge or ceiling covering the lines a and b; c, a step-grate; d, a door in front ot' cooling-chamber or ash-pit, and c a door for closing the entire opening to the furnace; f, an'opening for charging the coking-chamber with fresh fuel, and g the gas-conducting line.

One principal condition to the effective workiion-chamber or lire-place clear of clinkers and ashes. Gas-producers should therefore be constructed so that the remnants from the fuel can be quickly and conveniently removed withducer-chamber and without a waste of fuel. With these objects in view I have constructed thelowerpartoftheproducingchamber, known asthecombustion-chamberorire-place,of suitable width transversely, according to the size of the producer, but of limited dimensions in the longitudinal direction. Further, I have provided a hearth, B, at the bottom, upon which the body of the fuel rests, and have provided two openings above thehearthone in the front wall andthe other in the rear wall; and for the purpose ot' preventing the fuel from falling through these openings, I close the one in front by a step-grate, c, and I extend the rear opening backward through the rear wall of the combustion-chamber beyond the foot of the natural slope of the fuel in the producer. Therearopening-averticaldue,b thus communicates directly with the ash-pit or cooling-chamber D under the hearth, and indirectly through the flue rt under the bridge E with the combustion-chamber C.' With this arrangement an)7 clinkers or ashes accumulating in the combustion-chamber can be pushed backward through the horizontal channel a to the vertical iiue b, and there dropped into the ash-pit or cooling-chamber D.

The step-grate c in the front opening is more desirable than a grate with vertical or inclined bars, because it gives better support to tine fuel or coke, admits the largest possible quantity of atmospheric air, and above all affords easy access to all parts of the combustionchamber.

'Ihe rear spring, a, may be divided into sections by vertical or horizontal partitions.

The best material for the hearth is brick or tile; but it may be a metallic plate. A gate in place of the hearth is more subject to wear and tear, and will cause more or less waste of fuel through the interstices between the bars.

The ash-pit D may be constructed as a tank to contain water, which as it is evaporated by the glowing clinkers will rise and be decomposed in the producer-chamber and will forni into combustible gases.

I am aware that it is not new to construct a furnace with a Step-grate, and I am also aware that it is not new to construct furnaces with a vertical line extending downwardly from the rear of the hearth to the ash-pit; but I am not aware that any furnace has been constructed prior to my invention thereof having a solid hearth-plate, a combustion-chamber of less dimension longitudinally than transversely, and having an openingin the'front wall IOO closed by n siepgrme, and a. rear opening exlendedbnek through thx rear Wall of the coinbnstion-ellainber, and a horizontal flue, a, and vertical Hue. b, bridge Egnnd coolingehamber D. s shown and described herein.

Vha-t I claim is- A gus-producer having ookng'clinmber A,

` solid hearth-plate B', combustion-chamber (j,

of less dimension longitudinally than trans versely, and having openings in the front and rear walls, respectively, said front openings being closed by a mangiate, c, and said rear openings being extended backward through the rear wall of .the combnstion-chamber, as described, the horizontal ilue a, and vertical fine b, und the coolingellainber D, und bridge E, snbstzintiallyas and for the purpose set forth.

In testimon7 that I claim the foregoing as my invention I at'x my signature in presence zo of two witnesses.

JOHN ZELLWEGER.
