CHARLES WILLIAM CRAWFORD, OF HEIDENHEIMER, TEXAS.

' corrou CLEANER AND FEEDER.

Specification of Letters Patent.

Patented Oct. 30. 1 b

To all whom, it may concern:

Be it known that I, CHARLES WILLIAM CRAWFORD, a' citizen of the United States, residing at Heidenheimer, in the county of Bell and State of Texas, have invented a new and :useful Cotton Cleaner and Feeder, of which the following is a specification.

This invention relates to cotton-cleaning.

which will be hereinafter fully describe and particularly pointed out in the claims;

In the accompanying drawings has been illustrated a simple and preferre form of the invention, it being, however,. understood that no limitation is necessarily made to the recise structural details therein exhibited, ut that changes, alterations, and modifications within the scope of the' invention may be made when desired.

In the drawings, Figure 1 is a vertical sectional .view of a cotton-cleaner and ginfeeder constructed in accordance with the principles of the invention. Fig. 2 is' a detail vlew in elevation of the feed-roller detached from: the casing. Fig. 3 is a top plan view, enlarged, of the operating mechanism. Fig. 4 isa sectional detail view taken on the plane indicatedby the line'4 4 in Fig. 3. Fig. .5 is a sectional detail view taken on the plane indicated by the line 5 5 in Fig. 1 and showing a slight modification in the construction of the feed-roller.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

A suitably-constructed casing C is provided, said casing having suita ly-disposed hinged doors, as D, through which access may be had to the interior. The casing is provided with bearings for a shaft 1, carrying a feed-roller 2, which is dis osed directl be-' neath a hopper or inlet 3, t rough which the cotton who is to be operated u on is supplied to the machine. The fee -roller 2 is provided throughout its lengthwith annular Application filed April 2,1908. Serial No. 309.421.

grooves or corrugations 4 4, which have been shown of approximately semicircular crosssection, the said grooves being spaced apart by ribs 5 5, which have been shown to be of a width about equal to the diameter of the grooves. The'ribs 5 5 are provided withradially-extending pins 6, which in a full-sized machine will be about one-halfof an inch in length. The back of the casin is curved concentrically with the axis of t e shaft 1,

of the oors D is located. Above said. door is a h' ed deflecting board or plate 6, Sn ported in operative position by an le brac e ts or rests 7 and serving to lessen t e weight of cotton on the feed-roller 2 and to avoid clo ging'of cotton in the space between said roller and the adjacent wall of the casing. By hinging the deflecting-board, as shown, access may be had to theinterior of the cotton-chute 3 through the proximate door D.

Hingedly supported at the rear wall of the chute 3 is a rearwardly-curved shield or deflector 11, which is sup orted adjustably in operative position, as means of a setscrew 8, whereby said deflbctor may be readily adjusted to various positions, as shown by full and by' dotted lines in Fig. 1'. By this devicethe area of the feed-aperture may be varied in order to regulate the feed.

Suitably supported for rotation in the casing C in advance of the shaft 1, carrying the feed-roller, are shafts 9 and 10, caniiin w c picker-rollers 11 and 12, the former of 1s disposeda'bove the latter. The rollers 11 and 12 are provided with radially-extending picker teet or pins, 13 and 14, adapted to carry the cotton over and in contact with'the screen- surfaces 15 and 16, which are su ported within the casing adjacent to t e rollers 11 and 12, respectively, said screens being supported in part b means of a brace 17 within the casing. T e screen 16 has a hinged portion 16*, which may be moved to an open position when desired to afiord access to the surface of the picker-roll 12 for the x 5 carryin the feed-roller, in front'of which one I purpose of removing such obstructions as ma lodge between the roll and the screen an which would not otherwise be conveniently accessible.

The screen 15 is also sup orted by a crossbar 15, adjacent to which is arranged a longitudinally-adjustable' crossbar 16, which atter may extend throu h slots, as 17, in. the end walls of the casing, which may be provided with supportin -screws, as 18', engagin nuts 19, swivele in the ends of the crossar 16, which may thus be nicely .adjusted. Said cross-bar is rovided with notches 20 for the assage o the teeth 6 of the feed-roll, with re ation to which the crossbar 15 ma be spaced sufficiently to enable a portion 0 such coarse impurities as may be contained in the cottonto be separated at this stage.

In Fig. 5 a modified form of the feed-roller has been shown, which consists in making said roller in the form of a true cylinder without the annular grooves shown at 4 in Figs. 1 and 2.

The brace 17 extends adjacent to the screen 16, so as to guide material passing through the screen 15 into the lower part of the casing C, where a screw conveyer .18 is arranged for the purpose of carrying the screenings and the impurities escaping between the feed-roller and the cross-bar 15 to a' place of deposit. The screenings passing through the screen 16 drop directly into the lower dpart of the casing, which is hoppersha e so that the screenings will be guided to t e trough 19, in which the screw conveyer is supported. The screen 16 is provided in the lowerportionthereof with a slot 27, in

which are disposed a plurality of inclined slats or deflectors 28, between which coarse impuritiessuch as avel, nails, bolts, and other bits of metal an the likethat are not capable of passing through the meshes of the screen may escape.

The cas' has an exit-opening 20, through which the c ean cotton passes over a slide or apron 21 to the hopper of the gin, which is represented in dotte lines at 22 in Fig. 1 of the drawings. The casing G is suitably supportedfor'operation upon the -stand, and the slide or apron 21 is prefera lysupported hingedly or otherwise movably, as at 23, in order .to aflord access to the gin-brush.

The shaft 10, is driven, as by means of a pulley 24'and' a band 25, from the source of power, which may bethe saw-shaft of the gin in connectionwithwhich the feeder is employed. Motion mayl be transmitted from the shaft 10 to the s aft 9, as by means of a belt 26, said shafts being rotated -in the same direction. The shaft 10 extends through a bracket 29, which is secured upon the casing G, as by means of bolts 30, and said shaft 10 carries -a pinion meshing with a pinion 31 upon a shaft 32, which is journaled in said bracket 29. The shaft 32 carries a worm 33, meshin with a wormgear 34 u on one of a pair 0 approximately parallel. shafts 35, which are supported for rotation lengthwise in the bracket 29, said shafts 35 being longitudinally slidable in their bearings. The shafts 35 are provided with inter-meshing pinions 36, said pinions, as well as the worm-gear 34, being sphned rotated. To regulate the u on the shafts so as to rotate with the latter,

e forward ends of the shafts 35 35 are connected by means of a yoke 37, through which operates a screw 38, having a hand-wheel 39, said screw being swiveled 1n the bracket 29. The shafts 35 are provided with frictionwheels 40, frictionaly engaging a frictiondisk 41 upon the shaft 1, carr ing the feed roller 2, which latter may be t ereby slowly s eed of rotation, the shafts 35, which are disposed at right angles and radially to the shaft 1', may be moved by the adjusting-screw 38 to regulate the distance of the friction-rollers from the axis of the shaft 1.

In order to enable wear upon the frictionwheels 40 to be compensated for, it is preferred to support the shafts 35 partially in boxes 35, transversely slidable in suitable ways in the supporting-brackets 29 and having" threaded a ertures e aged by a right and left screw-t readed re 36, operable by a handle 37, whereby the boxes may be moved toward each other to cause the wheels 40 to grip the disk 41. The movement necessary to effect this result is so slight that the ordinary looseness of the shafts 35 in their respective hearings will permit said shafts to be displaced to the needed extent from their normal parallel relation.

The pinion 31 is mounted loosely upon the shaft 32, and the hub of said pinion has a clutch member 42, adapted to be en aged by a clutch member 43, which is slida le upon and rotatable with the shaft 32, said clutch member 33 being operable b a shipping-lever 44, whereby it ma be p aced into or out of enga 'ement with tlie clutch member 42. When t e clutch members are out of eng ement, the pinion 31 will rotate idly upon ie shaft 32 and the movement of the feed-roller may thus be interrupted when desired.

From the foregoing description, taken in connection with the drawings hereto annexed, the o eration and advantages of this invention w' 1 be readily understood by those skilled in the art to which it appertains.

The feed-roller will be rotated at a low rate of speed, which is, however, capable of being governed by simply adjusting the shafts 35 y means of the screw 38. The cotton, which may be placed in the hopper 3 by an desired means, will be conveyed by the fee roller through the aperture 7 and will then be laid hold of by the picker-roller 11 ,whereb it is carried over the screen-surface 15, whic is of relatively fine mesh and through which dust and small impurities mayesca c. When the cotton leaves the roller 11, his laid hold of by the picker-roller 12 and is thereby carried over the screen-surface 16, which is of coarser mesh and through which coarser impurities may escape -nails, bits of iron,

and the like assing over the deflectors 28 in the slot 27. rom the roller 12 the cotton,

which has now been cleaned and purified, will pass through the exit-slot and over the slide 21 to the gin. I

This improved cleaning and feeding device is simple in construction, easily installed and regulated, and thoroughly efficient for the pur oses for which it is provided.
