COTTON COMBER AND CLEANER.

Application filed November 3, 1925.

This invention relates to new and useful improvements in cotton gin machinery and in such connection it relates more particularly to a means whereby the cotton may be subjected to a combing and cleaning, or reginning process.

The present invention is a continuation in part of an application for patent filed April l, 1920, Serial No. 370,483, for cotton comber and cleaner.

In cotton ginning a considerable amount of cotton falls to the floor in the process of ginning and pressing. Such cotton is gathered up and baled and contains the dirt and l of the saws arranged in spaced relationship on the shaft comprising the saw cylinder.

lt is the principal object of my invention to provide a saw cylinder whereon the teeth are so arranged that all availablefspace of the cylinder is utilized against the cotton, a nd providing means for adjustably feeding the cotton to the cylinder, also to provide a I'icylinder' in removable sections'. for convenience in repairing the cylinder, the worn or damaged part being thus adaptable to removal without replacing a completely new cylinder. Y Y

Another important object of the invention is to provide a plurality of feeder-disks arranged on a shaft and'provided with means for spacing the disks thereon.

@si further and important object .if the invention is to provide a means for controlling the feed drive by a belt tightcner and unique arrangement of gears hereinafter referred to.

A final object of the invention is to provide an air blast arrangement for conveying away the dirt and trash from the cotton.

With the foregoing objects in view the invention will be better understood by reference to the following description, taken in rollers 3 3.

Figure 3 is a side elevational view, partly in section and partly broken away.

Figure 4 is an enlarged detail view of the belt tightening and drive control means, Figure 5 being. a sectional viewl thereof along line 5 5 of Figure 4.

Figure 6 is a detail'view of one ofthe feeder-disks, Figure 7 representing a spacer ring therefor. V

Figure 8 is a detail View ofa supporting bracket and link providing for adjustability of the feeding mechanism.

Figure 9 is a fragmentary view of the toothed cylinder for combing the cotton and pulling it into ythe machine, Figure 1,0 being a sectional view thereof along line 10 10 of Figure 9. I

Figure ll is adetail view of the shaft upon which the feeder disks are mounted.

In carrying out the invention, there is provided a housing l with a 'hopper 2 and upper feed rollers 3 3 mounted on shaft 3. Each'shaft carries a gear 3b, the gears meshing one with the other. The rollers 3 3 are provided with teeth 3d. These upper rollers, however, are not claimed as a part of the invention and are described only for the sake of clearness. Y

Roller 4 which is of longitudinal rib formation is mounted upon a shaft 5. This shafthas its ends supported in a pair of links 9 depending from a'fraine 10 (only one of the links and frame being shown), clearly illustrated in Figure 8. The frame 10 also supportsv the shafts of the two upper It will be observed that a spring l2 is supported against the links and has a support 13.' rfhis is for the purpose of permitting the roller 4 to move outward under pressure of the cotton when the saine is fed downward from the upper rollers to relieve any undue pressure or lumps in the cotton and thus regulates the feed.

A shaft 6, of square formation along its main portion, as shown inFigure 11, has the rounded parts thereof also vseated in the frame l0 at the apertures l1. Supported in spaced relation upon the squared portion of the shaft are a plurality of saw disks 7-7. Each disk has a squared opening to fit the shaft and between each disk is a spacer ring 8. Pins 8a hold the outer disks in place.

On the frame 10 is an arm 14e with screw for adjusting purposes to bring the disk shaft 6 and roller shaft 5 to or away from the cylinder 20.

One end of one of the shafts 3a carries a 'sprocket gear 16 and is connected by a chain drive 17 to a similar gear 18 on the shaft 6. rllhe driving power for the sprocket gear 18 is provided for through a shaft 19 by means of a belt and a pulley referred to herein after.

@n the shaft 19 is mounted a plurality of drums 20, forming a cylinder and connected together by a plurality of circular web members 21. The object of this arrangement is to enable a portion of the cylinder .to be repaired and replaced, Without providing an entirely new cylinder'. rlhe periphery of the cylinder formed by the sections is provided with a number of teeth 22. By reference to Figures 9 and 10 it will be observed that these teeth are so arranged that they form a part of the cylinder and are set in rows so that the spaces between one row are directly opposite to the teeth in the next row, the object being to utilize all the space on the cylinder.

Referring now to the means employed for driving the mechanism, by reference to Figures 2, 3 and 4;, it will be seen that there is mounted on shaft 19 a pulley 22 and on shaft 6 beyond the gear 1S there is secured a pulley 23, the pulley and shaft being connected by a belt 24. Shaft 6 carries on one end a fixed gear and a loose gear 26, gear 26 having 415 teeth and its companion or inner gear 46 teeth. 130th of these gears are within the pulley. The pulley has several depending arms or spokes forming supports for gears 27 and 28, connected by small shafts 2.9.

T he outer gear Q6 carries a lever 30, rigidly fastened thereto. rThe outer end of the shaft 6 revolves slowly in the center of gear 26, the cap screw 31 being for the purpose of stabilizing the shaft and revolves loosely with the shaft through an aperture in the lever 30. The cap screw is not connected to the lever. On the lever is also carried a roller 32 which is advanced against the belt in the tightening movement. The shaft 19 revolved by the pulley 22 causes the belt when tightened. to revolve the pulley 23. rEhe shaft 19 revolves at approximately 500 revolutions per minute. The small outer gears 27 and inner gears 28 thus revolve in a planetary movement around the gears Q6 and 25 due, however, to gear 25 having one more tooth than its companion 26, the small gears Q8 will thus move the gear 25 around and rotate the shaft 6 at a slow rate of speed. ln other words, the effect of the arrangement is somewhat similar to an effect which would be produced as if the gears 25 and 26 were connected by chain belt-one of the gears being of slightly greater diameter, a tension is thus produced on the belt through the lever` 30 and the roller 82. The additional tooth, however, provides for the movement of the shaft 6. 'When the lever 30 is moved away from the belt 24 the entire mechanism is stopped, with the exception of shaft 19.

Referring to Figure 1, the cotton on its downward movement is caught by the teeth of the cylinder 2O and by a combing and pulling motion is dragged from the disks 7 and roller el. The dirt and trash is thus thrown by centrifugal force into the chute 53 formed by the upper and lower aprons 33, and an air blast from an air chamber 3a carries the refuse away.

rlhe cleaned cotton falls into a chute 35 and is conveyed away by an air blast from air chamber 36, the latter arrangement being no part of this invention.

It should be understood that modifications and changes may be made in the arrangement and construction of the invention in keeping with the spirit and intent of the following claims.

1 claim:

1. In a machine for combing and cleaning cotton, the combination of a housing including a shaft carrying a saw cylinder', a frame consisting of a pair of plates having spaced apertures forming bearings for spaced shafts carrying feed rollers and apertures for a .shaft carrying saw disks; said plates having a curved and inwardly-extended leg, adjustably fastened to the housing and including means for adjusting said leg to move the shaft of the saw disks to and from said saw cylinder; links pivotally depending from said plate and having apertures for supporting a .shaft carrying an idler roller.

2. A machine as set out in claim 1, said idle roller being adapted to swing to and away from said saw cylinder by the pressure and feeding movement of the cotton downward into the machine; said links movable under spring tension.
