1,085,686. i Application filed March 9,

To all whom t may concern Be it known that I, EBENEZER A. IV. Jnrramas, a. citizen of the United States, residing at Worcester, in thecounty of Vorcester and Commonwealth of Massachusetts, have invented a newl and luseful Improvement in Gas-Producers,fof whichV the following is a specification, accompanied by a drawing forming a part of the same and representing a. side velevation-of a gas-producer, .shown in central vertical sectional view" and embodying my present invention.

Referring to the accompanying drawing, 'ldenotes a gas producing chamber and 2 the gas producing chamber. Mounted lupon, the bottom of theash pan is a centralair chamber 3 to which air under pressure is supplied through a supply pipe 4. llhrough openings in the top of the chamber vavblast of air is delivered tothe interior of the gas producing chamber in order to support comgas producing chamber from a hopper The above mentioned parts of the apparatus form'no part of my present invention and may be of any known and usual form The lower portion of the casing surrounding the gas producing chamber consists, preferably, of a metallic wall 6 surrounded by an annular chamber 7 'which-is supplied with water in order to prevent the undue heating of the metallic wall 6. In t-he present instance water is supplied to the annular chamber 7 by an overflow pipe 8 leading from a water chamber 9 formed on the cover of the gas producer for the purpose of water. sealing the fuel feeding mechanism'. The annular chamber 7 is also provided with an overflow pipe 10. A

Inclosed Within the annular chamber 7 is a coil of pipe 11 communicating at one end, through a pipe 12 wit-h a source of water supply and at the opposite end, in the present instance, through a pipe 13 with a pipe 14 passing diametrically through the gas producing chamber 1. The pipe 14 is connected with a pipe 15 which enters the air supply pipe 4 and communicates with a vertical pipe 16 through which water, heated by its passage through the coil 1 1 and pipe 14, is delivered int-o the air chamber 3 through nozzles 17, 18 and 19 at the top of the vertical pipe 16. The deIiVerythrOugh Specication of Letters Patent.

f In .the construction 37 and 18 are directed 1,910. serial No. 543,172.

the nozzles is, preferably, in the. form of a spray which facilitates a thorough admin'.- yture of water with the au.' passing into the Patented Feb. 3, 1191/11.. i

gasproducing chamber through the suppiy pipe 4. ward through the nozzle 19 strikes a cap' or baille-plate 2O and, that portion which falls byl gravity, p-lateQl fronrthe edgeof which water falls downward lmeeting theupward current of air which lissupplied from any suitable source of air 'supply under pressure such,` for example, ias a pressure blower, or other means now employed for forcing an air blast into the gas producing chamber.

shown in the present dra-wing, the air chamber 3 communicates with chambers inclosed by the radiating arms 22, 2Q and the nozzles toward the chambers inelosed by these arms so that the spray of water will be delivered into each of the chambers, that lodging in the chambers being converted into steam and carried out into the gas producing chamber by the air blast, through slots 28. Y

It has been customary heretofore to ad mit a mingled current of air and. steam through the supply pipe l to the gas producing chamber, the steam being admitted under pressure in the form of a jet, the force'ofwhich served to induce an *air current which,

mingling with the steam, was admitted to.

the gas producing chamber' to support cornbustiou. By my present improvement force a current of air under pressure through the pipe, and supply the requisite moisture by vaporizing the water admitted to the air chamber 3, preferably inthe form of a spray, .the water supply having been preheated by heat generated inthe gas producing chamber.

I do not confine myself to the specific constiiuetion shown and described for the purpose of imparting heat to the wat-er supply, *butl I have shown what I deem to kbe a preferable and convenient method of imparting heat to the water su ply b conductinoa the P s water through the coil. of pipe 11, preferably of copper, submerged in the water contained in the annular water chamber 7, which becomes heated by heat generated within the gas producing chamber and conducted through a commonxnetallic wall G. I- thereby "avoid the -extra cost involved in The' water passing verticallyv up-z of a gas producer, as

is received upon a conical shield Y icc ber, I am able to reduce g vconverting the water into steam by the method now commonly practised, and also 1. In a gas' producer, the combination'` with a gas producing chamber, of a watercooler for a part of said chamber, an air inlet pipe for the admission of air to said chamber, and a Vwater pipe leading from a vsource of wat-er supply to said inlet pipe and' inclosed within said water cooler,

whereby the-water in said water pipe is heated by the heat of the water in said water cooler,

2. In a gas dproducer, the combination with a s pro ucing chamber, of a Water cooler or a part of said chamber, an air inlet pipe for the madmission of air to said chamber, and a water-pipe leadmg from a source of water supply to said inlet pipe and passing throng said water cooler.

3. n a gas' with a 'gas pro ucing chamber, of a water cooler for a part of said chamber, an air inlet pipe for the admission of air to said chamber, and a water pipe passing through reducer, the combination fammes@ said water cooler and through the'fire in said chamber and discharging' into said inlet pipe. K

4. In a gas producer, angas producing chamber, an air' inlet -pipe to said chamber, an annular water chamber surrounding said gas producing chamber having a common dividing wall, a coil-of pi e inclosed in said water chaumber, a pipe eading from one end of saidcoil .to a source of water supply, and a pipe leading from the oppositeend of said coil to the mterior ofvsaid air inlet pipe.

5. In la vgas producer, chamber, an inclosed air chamber, an air supply pipe leading tosaid air chamber, hollow arms extending laterally from said air chamber-into said gas producin cham-v ber and 'having openings for the elivery ,of air thereto, means for supplying water to the interior of said hollow arms, and means for preheating the water supply by heat generated in the gas producing chamber.`

In a gas producer," .thecombination with a gasproducing chamber, of anair chamber inclosed in s aid gas producing chamber, means for supplying air under a .gas producing pressure to said air chamber, hollow arms communicating with said air chamber and extending into said gas producing chamber and having openings thereinto, and means forl supplying preheated water in the form of a spray to said air chamber.
