2 sheets-sheet 2 Filed Aug. 24, 1929 mii Patented Aug.. 26, 1930 JOSEPH BEHLE, on DALLAS 'rnXAs` Assrcivo'a ro 'ri-rn MURRAY COMPANY, or DALLAS,

TEXAS, A CRPGRATON OF COTTON FEEDER y Application sied August 24, ieee. serial No. 388,217. L

Thisv invention relates` to a cotton feeder, and particularly generally shown in the patent to lV. L. Hancock for cotton gin feeder, No. 1,719,294, July 2, 1929, wherein the cotton is cleanedv during its feeding movement and foreign.

cotton already cleaned.

This invention has for an object to' pro-A vide a novel and improved construction including a plurality of conveyors at the lower portion of the cleaner casing geared for oint operationl and all deliveringv at the discharge point for the foreign matter.

A. further obj ect of the invention is to present a new arangement of parallel conveyors having oppositely disposed blades and thel shafts thereof directly geared together to effect a feed of both conveyors in the same direction.

@ther and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings: f

Fig. 1 is a central vertical transverse section,

Fig. 2 is a longitudinal elevation of the lower portion of the cleaner with part in sec- Figure 3 is a detail end view from the right of Fig. 2.

Like numerals refer to like parts in the several figures of the drawings.

The general construction of the cleaner is shown by the Patent 1,719,294 before mentioned, and comprises the casing 1.() having the hopper 11 and feed rollers 12 discharging upon the toothed drum 13. Spaced from p to a construction such asis v this drum and from the casing is ascreen 14 extending at the rear and below the drum, while atthe front a ldischarge chute 15 is provided. Y v Y y. Y f

The section of casing at the reary is usually pivoted at 16y upon longitudinal angle to permit access yto the drum. For the purypose of mounting the screen in spa-ced relation to ther casing, skeleton frames 19V are provided, the screen being secured to a flange 2O at theiriirineredgeY and the casingI 10 to a flange 21 attheir outer edge, n f f The screen section 22 beneath the drum 13 is carried at thereary by an angle iron 23 and at the front by a similar iron 24 which also spaces the casing of the trough 25 from the irons 17 vand 18 to'swing upward and outward screen. yThe cut-off sheet 26 is supported above the discharge chute by an angle iron 27 i and also byr ribs 28 extendingY upward therefrom., y, i

At the base of the d disposed parallel screw conveyors 30 and 31 having right and left spiral blades respectively,wthesh'aft 32-from the screw'30 carries a gear 33 directly meshed with thegear 34 on the shaft 35 of the screw rihis direct rt `trough l25A IL have drive iskmost efficient but causes the rotation of the shafts in opposite directions,- and this compensated by the direction of the conveyor. blades so that both deliver the dirt into a cas-A ing 36 upon a` conveyorhead 37 atene end of themachine-whichis usually connected vto a source of air suction. Y

The drive shaft 38 foryone conveyor eX-J tends through this casing and is provided with the usual drive pulley and belt, as at 39.

At the Vopposite end the conveyor shafts 32A and 35 are mounted in a head 40 which carries a gear cover 41 recessed at its lower end to partially embrace the shafts. l

rlhe general operation of the machine is as described in the patent before mentioned upon which this invention is an improvement, and in the practical operation of such a cleaner the amount of dirt and foreign matter collected is much greater than can be eiliciently discharged bythe dirtconveyor at the base, so that the present invention increases the conveyor capacity and provides for a direct drive of a plurality of conveyors to discharge at the same outlet. The invention also perfects the screen support by utilizing angle irons and a skeleton frame for that purpose.

While'thespecic construction of the several parts has been shown and described, the invention is not conlined thereto as changes and alterations may be made Without departing from the spirit of the invention as recited in the following claims.

,What I claim is:-

1. In a cotton feeder, af casing, a drum therein, means for feeding cotton thereto, a screen spaced from the drum and casing, a dirt trough beneath the drum having oppositely inclined Walls, parallel conveyors in said trough having oppositely disposed lades, feeding from Vthe inclined Walls to- Ward they center of the trough, a discharge from all conveyors located at the same end y thereof, and means for driving the shafts of said blades in opposite directions.

2. In a cotton feeder, the combination of a Y casing having an inlet hopper and discharge chute, a drum Within the casing having means to convey cotton from the hopper to the chute, a curved skeleton frame secured to the ca-sing at the rear of the drum and having .lateral flanges at its inner and outer faces, a

screen carried by the innerliange of said frame and spacedfrom the drum, the outer flange of the frame carrying the casing to form a dirt collecting chamber, a dirt trough having inclined Walls and communicating With said chamber, a conveyor in said trough, and screen between the drum and trough extending from the conveyor to the discharge chute. Y

3. The combination defined by claim 2, and a out-off sheet disposed above the discharge chute and extending circumferentially of the drum'toward the inlet hopper.

' 4. The combination defined by claim 2, in

Which the conveyor comprises parallel shafts having oppositely disposed blades feeding from the inclined Walls toward the center of the trough, meshing gears on said shafts to drive the same in opposite directions, and a gear cover secured to the casing and depending over said gear-s.

In testimony whereof Iali'iX my signature. l JOSEPH BEHLE.
