' Specification of Letters Batent.

Patented May 6.' i 913.

Application filed July 16, 1912. Serial No. 709,751.

To all whom it may concern.'

Be it known that I, WALTER HAMMioii, a

Acitizen of the United Sta-tes, residing at Pittsburg, in the county of Crawford and State of Kansas, have invented a new and useful Gas-Producer, of which the following is a specification. 1

The device herein disclosed is adapted t be used for the making of gas, and the invention aims to provide novel means for creating a draft and for disposing of the gas, and to provide novel mechanism whereby the aforesaid means, anda coal trimmer, may be actuated simultaneously.

`With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of vparts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be "made within the scope of what is claimed without departing from the spirit of the invention.

The drawings show a side elevation partly in section of the complete apparatus.

In the drawings` :20 designates a cylindrical furnace. the lower terminal 21 of which is embraced by the flange 14,of a conical fire box 15, provided with a grate 15a, the lower flange 18 of the fire box being received in the upper end of an ash pit 16, the lower end of which carries a slidable ash door 17. Legs 10 are provided, and the flanges 11 of the legs are secured to the parts 14 and 21 of the .tire box l5 and the furnace 20 respectively. Braces 19, which may be angle irons, connect the legs 10 with the upper end of the ash pit 16.

The upper terminal 22 of the furnace 20 is closed by a cover 24 provided with a flange 25 which embraces the furnace. The cover 24 is provided with an obliquely disposed intake chute 24', the passage of coal through the 'saine being controlled by a shutter which is pivotally supported on the cover 24.

In the side wall of the furnace 20 there is a stoke opening 39, controlled by a closure 39a. The closure may be provided with an opening, across which a plate mica extends to permit the gas producing operation to be observed.

The last specified details are Well known in the art and need no illustration.

A spider-.28 is connectedperipherally to the furnace 20, at a point adjacent the up.-

per end ofthe furnace. The Vdischarge end 2G of the intake chute 24 extends below vthe spider 28. The spider supports a shaft 29, the lower terminal. of which is reduced and screwfthreaded as at 33, to receive a nut 32 engaging the hubof a coal leveler 31'which is keyed to the shaft 29. The hub of the leyeler 31 engages the hub ofthe spider 28 and tlius the shaft 29 is held against upward movement. The leveler 31 is shaped like the propeller wheel of a vessel.

A.l draft through the furnace 2O is maintained by afan 34 driven by a motor 34a mounted upon a frame 35, there being a conduit 36 connecting the fan 34 with an opening 37 in the fire Abox 15, the opening 37 being protected by a screen 3S which prevents.

ash and braize from entering the conduit.

The gas is removed through a conduit- 40 which communicates with an opening 4l disposed adjacent the upper end of the furnace 20, the opening being protected by a screen 42' which prevents the ash or braize from entering the conduit 40. Suction is created in the conduit 40 by a fan 41 having an out let 41". The fan 41 lis supported by the upper bar 44 ofthe frame The fan 41 is driven from the motor 34a by a belt 46 which passes over a sheave 47 secured to the shaft 41a ofthe fan 41. Beveled gears 4S connect the shaft 41a with an upright shaft tcarry ing a sheave 50 which drives a belt QQ the belt 2.9 being trained about a stre/avc 30 which is secured to the end of the shaft 29, .whereby rotation is imparted to the coal leveler 31. It will be noted that by this constructionthe fans 41 and 34 and the coal leveler 31 may be driven from a common source of energy which may be the niotor 34a, the saine being of any suitable character. 1n practical operation, an initial charge of coalis placed in the fire box 15, and the .tire is lighted. Subsequently, the vcoal is fed through the chute Q4 although the coal may be fed through the opening 39 if desired. The coal, passing through the discharge end 26 of the chute 24, is delivered below the spider 2S and upon the leveler 31 which, rotated rapidly, vwill distribute the coal iwithin the furnace 20. The ashes forming upon the grate 15i will drop into the ash pit 16, the

slidable door 17 permitting the removal of the ashes at any time. lVhen the motor 34 is inoperation, the belt 46will be actuated, rotation being imparted to the sheave 47 and to the shaft 41l1 of the fan 41. When 5 tatory l5 VArgasi" producer comprising 'a furnace,.a

{he shaft 41a of the fan 41 is actuatcd,vrota ion will loe-imparted to the shaft 49, through shaft 49 and tothe the medium of the pulleys() andv 50,l and the belt 29. rIhe motor-34, of course, drives the fan 34. Thefan 34 createsa' forced draft 10 to the coal inthe fire box- 15, 'and .the fan 4&5 creates a suction which draws away thef gas, the:` gas being discharged through the outlet 41. v t a WhaLSnlaimed is:

'suction fan supported on lthe frame and including a shaft gv a rdraft fan Supported upon the frainegva conduit connecting the draftj fan With the re box; a conduit connecting the suction fan with the furnace; a motor 'operativelyI connected with the draft fan;

vmeans 'for 'connecting the motor with the suction' fan shaft; a secondary shaft disposed .parallel'to the primary shaft; means for operatively connecting the secondary shaft with the'sucti'onfanf shaft ;A Aancla beltlcony necting Ithe primaryffand w s econda-ryshafts.
