ROLLER COTTON-GIN.

SPECIFICATION forming part of Reilsued Letters Patent No. 12,042?, dated October 7,1-902. Original No. 701,814, dated .Tune 3, 1902. Application for reissue filed -Tnly 31, 1902. Serial No. 117,853.

To ctll'whom t may concern:

Be it known that I, CHARLES JAoonMo- PHERSON, a citizen of vthe United States, re-j South Framingham, in the county siding at 5 of Middlesex and Commonwealth of Massachusetts, have invented Improvements in Roller (Botten-Gins, of which the following description, in connection with the accompany-- ing drawings, vis a specification, like letters on io the drawings representing like parts.

This invention relates to roller cotton-gips; and itl consistsin the features and in the construction, combination, and arrangement of parts hereinafter'described, and particularly l5 pointed out in the claims following the description, reference being had to the accompanying drawings, forming'a part ofthis' specification, wherein Figure l is a view in side'elevation of myl .Fig..2 is a vertical lon- Fig. 3

gitudinal sectional view-ot the same. is a detail end view of one of the comb-disks on the rotary combs for separating the seeds from the lint. Fig. t is an end elevation of z5 one of said rotary combs, and Fig. 5 is a partial side elevation and section of one of said rotary combs.

In the drawings, A A represent the side frames; preferably made of metal and secured' 3o at a proper distance apart by means of stays or braces in any suitable or desirable manner.

BVB represent the sides of the inclosi ng shell of the machine.

C is the hopper, into which the seed-cotton 3 5 is fed onto an endless traveling apron D, 1ocated at the bottom of said hopper, as is common' in devices ofthis kind. The endless apron D operates to deliver the seed-cotton to a rotary feed-cylinder F, provided with rows i V4o of teeth ff, which take the seed-cotton from the apron D'and carry it between the teeth of a comb G, which open 'the iibers of vthe cotton, and the feed-cylinder then delivers the cotton to a rotary cleaning-cylinder H, 45 inclosed in'a screen K. The cleaning-cylinder is :provided with a series of fan-bladesL, which serve to force air up through an upwardly-projecting chute or conduit N, which 'ginuingrollers O O, scoured to the shafts O' O', jou rnaled in horizontally-adj usta ble bearings O4 O4, located in slides in the frames A A and provided with a suitable adjusting de vice, as shown in Fig. 1. Each. of' such giuning-rollers is provided on its exterior With au annular covering O", and in contact with it is held a stationary bed-knife 03, as shown in Fig. 2. The covering O" of the rollers is 65 preferably of hard-felted material, such as hair or wool, which is'felted very hard-that is to say, not loose or fibrous, but hard and compact. The vrotary-felted rolls cause the lint to be fed between them and the stationary bed-knives O O3, while at the same time the seeds' are separated from the lint by the action of the rotarycombs P P, as shown. The lint is received into the lintlchamber Q and falls upon theendless condensing-apron R, 'which 75 which carries the lint to the press, as usual, or the lint instead of'being carried away on the apron may be blown awayor conveyed by an air-blast inthe usual way..v

' The apron R is supported upon a roller R andis fed onward by aroller R, above which is located a looselyrevolving condensingroller R3, which presses upon the cotton as it comes from the lint-chamber and forms a bat ready for the pressingand balingoperation, 85.

of toothed washers j; and spacer-disks p p',

`arranged intermediate between such toothed 'b means of clam inv-nuts i4 )4 screwed upon the screw-,threaded portions p5 p5 of said shaft, as shown in Fig. 4, and by this ar- 'rangement the said toothed washers p are held in their proper positions uponlthe rotary shaft p", as shown in Fig. 5.

The ginning-rollers O O may be adjusted relative to the bed-knives O8 O.8 so as to cause their felt coverings O" O." to be held in close contact with the upper edges of the bedknives O3 O3, thus compensating for any wearV that may take place from time to time on such felt coverings. i

The rotary combs P P may be adjusted u p and down, so as to plaoe'them in proper positions relative to the upper edges of the bedknives O3 O3, so as to obtain the best results in the carrying out of the ginning` operation.

In this my improved cotton-gin I causedirt, sand, and grit-ty particles to be expelled and separated from the seed-cotton by the action of the fans on the cleaning-cylinder H, and this is very essential and advantageous for the purpose of preventing the rapid wearing of the ginning device, as weil as preventing `fire taking place during the grinning operation.

The rotary spiral combs P I serve to comb or roll out the seeds from the seed-cotton while the latter is being held and fed onward between the ginning-rolls and bed-knives, by

which arrangement the lint is not injured or broken, causing its iibers to be left in the natural state, similar to the operation of pulling the seeds by hand labor.

By having the coverings on the ginningrolls made of hard-feited material, as hereinabove described, the heating of the bedknives is materially prevented, thus admitting a very high rate of speed of such ginningrollers.

The general construction of this machine is a great improvementon what are termed saw-gine and the operation is the opposite.

of such machines, in that the rotary combs in my machine act upon the seeds instead of upon the lint, .thus preventing the lint from d being torn or broken.

In practice I prefer to drive the machine by belt powerapplied to a pulley on the seedconveyer shaft and connect the latter by belts or gears to the various rotary shafts con taining the operative devices, and I Wish to state thatI do not desire'to coniine myself to any particular driving mechanism of the different shafts tra which the operative devices are connected, as this may be done in.

any well-known manner Without departing fromthe essence of my invention.

The operation is is follows: The seed-cotton is placed in the' hopper C and is fed in the manner described up through the conduit N and into the ginning-chamber N' and there conducted between theginning-rolls and revolving combs, causing the lint to be drawn between the grinning-rolls and bed-knives, while the rotary combs separate the seed from the lint. The seeds are conducted through the screen T into the seed-chamber T' and. automatically removed therefrom by the conveyor T". lThe lint after passing between the ginning-rolls and bed-knives falls into the lint-chamber, from which it is conveyed by the endless condensing-apron R to the press and baiing apparatus, as usual.

Having' thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claiml. In a cotton-gin, the combination of a rotary grinning-roll provided with a covering of hard-felted material; a stationary bed-knife fixed adjacent to such roll, and a rotary combroller consisting of a shaft, aseries of toothed washers arraugedon the shaft, and intermediate disks disposed between the toothed Washers, the teeth on the Washers beingdisposed in parallel spiral lines about the shaft, substantially as shown and described and for the purpose specified.
