LINDSAY. fa subject of theKingof Great Britain and Ireland 'andthe Isley of Man, .residing in Philadelphia, county of Philadelphia,l State 'l Pennsylvania, have invent-'ed .certain Im" provements in Coal-Feeders for Gas-Producers, of which the following is a specifi-, cation.l f

One vobject ofmy invention is to improve the construction ,of the mechanism for feed- .ing coal to gas producers so that the'lumps .of'coal vvill not bind upon the rotating feed- 1A farther Object of aie invention is' t0- `provide lmeans for distributing the coal as it-is discharged from the feederV into the y l 4body of the producer.

M invention also relatesfto" further detailsof construction- Which 'Willbe fully described hereinafter, reference being had to the'accompanyingdraw-ings, in which:

throughout its length, of any v'vi th desired'.

. The forward edge '17 yof this feeding cylinder is preferably round, as shown. l8`is a toothed drum which rotates in the same direction as the cylindrical feeder Aand is mounted on a'shaft 19so thatl as the coal discharges from the hopper 20 into the interior' of the cylindricalfeeder 15 and ,the

feeder travels underthe toothed roller, any' projecting lumps of coal will be thrown out,

bythe toothed roller so that the feeder 15 can Iturn freely into the discharging position. The toothed'roller is located Within a recess formed inthe hoppen-:as shown, and

its shaft 19is driven from a gear Wheel 21 on the -spindle 22' of the rotating feederl through an .intermediate gear- Wheel 23 and a pinion 24 on said shaft 12, -so that,`in the present instance, the'roller is rotatedgat-a greater speed than the feeder. The spindle .22a of thev feeder 15 is connected 'by-a coupling 25 to a driving shaft 26. adaptedto suitable bearingson theproducer. On this driving shaft-is a ratchet Wheel 27 and connected by a rod29 to power mechanisml and also on'this arm is a pawl 30engag1ng with the -teeth of the ratchet wheel 27 '2 In order'to regulate the feed, I provide an adjustable curv'edfplate 31 which .can be" A moved over thesurface of the ratchet Wheel .27 so'as to cover more or less of the teeth and to prevent their engagement lby the 4same amount of movement., The plate 31 has a slotted projection 32 through' which Aextends a bolt33 provided'with a wmg nut which will retainthe plate inany. position to lwhich, itl isl adjusted..`
