CLEANING MECHANISM FOR COTTON-HARVESTERS.

EJPECIFICATION forming part of Letters Patent No. 313,278, dated March 3, 1885.

Application filed May 13, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GERARD BEEKMAN, a

citizen of the United States, residing at New York,in the county of New York and State of New York, have invented a new and useful Improvement in the Cleaning Mechanism for Cotton-Harvesters, of which the following is a specification.

My invention relates to and is especially adapted for the mechanism for cleaning the cotton from the class of pickers for cottonharvesters described in the application for the same filed herewith; but it is applicable also to other harvesters, particularly the bar- Vester described in Letters Patent granted to me May 25, 1880, No. 227,949, and is an improvement upon the cleaning-rollers therein shown.

The objects of my invention are, first, to provide an improved form of cleaning-rollers, and second, to provide a method of adjusting these rollers to and from one another and to and from the pickers.

I attain the objects of my present invention by the mechanism illustrated in the accompanying drawings, in which Figure l is a perspective view of the rollers and their bearings, and the rod around which their relative position is adjusted. Fig. 2 is an enlarged perspective view of the upper end of said rod, showing the upper adjustingscrews and detached from the same, the upper carrier of the steel roller, and the slots through which the screws pass. Fig. 3 is a plan view of the rollers, rod, screws, and upper carrier, showing also the position of the picking device.

A B, Fig. 1, indicate portions of the frame of the carriage such as shown in my Patent No. 227,949, or of the improved adjustable frame carrying the picking mechanism, as shown in my application No. 131,303, filed of even date herewith.

O is the rubber cleaningroller,and D is the steel cleaning-roller, rotated by contact with the rubber roller. These rollers extend from the top to the bottom of the frame, and are preferably about three feet long. The rubber roller is preferably about two and a half or three inches in diameter at the largest part. The steel roller is as small as it can be made without buckling, and, preferably, about onehalf to three-fourths of an inch in diameter at the largest part, and I prefer to strengthen and stiffen it by making it thicker in the middle than at the ends, as shown in Fig. 2. \Vhen this is done, the rubber roller also must be made to taper toward the ends in exactly the same ratio, so that the rubber will not be twisted upon the core. The core of the rubber roller should be square, as shown at T, Figs. 1 and 3. The rubber roller is operated in any suitable way, but preferably by the gear-wheel E, .which is connected with the main driving-wheel of the machine, as shown in my application No. 131,303, above referred to. The roller should preferably be given about eighteen or more rotations to each revolution of the main driving-wheel of the machine.

Sis the rotary picker, provided with wire picker-teeth.

I find it best in practice to place the steel roller in advance of the rubber roller, so that the cotton upon the picker will strike it first; and I prefer to place it in contact with the picker, as shown in Fig. 3. The rubber roller is preferably placed so that the picker will not touch it. The advantage of this arrangement is that the cotton will be dislodged from the points of the picker as they touch the steel roller,and will be carried between the rollers, and the points of the picker will not abrade the surface of the rubber roller and cause cotton fibers to adhere to it. As the points of the picker become worn down by use, it will be important to advance the steel roller toward it; but in ordinary practice it will be sufficient to be able to regulate the pressure of the rollers upon one another.

The method of adjusting the rollers toward one another and toward the picker is accomplished as follows: v

F is a bar of iron or steel firmly attached to the frame A B, and serving as the base to and from which the steel rollerD is adj usted. This roller D has its bearing in the L-shaped brackets G H, which are preferably attached to a shield, I. Each of these brackets is provided with a slot, K, through which slots project the screws]? B, respectively. Each of said brackets is provided with a hole, J or M, through ICO which project the screws 0 and Q, respectively. All of said screws pass through the said bar F.

When it is desired to move the steel roller nearer to the picker S, the screws 0 andQ are turned so that the heads will approaehthe bar F, thus advancing the L-shaped brackets G H toward the picker, the slots K allowing the brackets to slide upon shoulders at the ends of the screws P and B. When it is desiredto withdraw the steel roller from the pickers, the screws 0 and Q, are turned in the opposite direction, when the rotation and pressure of the rubber roller 0 will move the steel roller backward.

In order to press the steel roller D more closely upon the rubber roller 0, the screws P and R are turned so that their heads will approach the bar F, and the other ends of said screws, bearing upon the L-shaped brackets G H, will cause them to approach the rubber roller 0, the brackets turning upon the pivots formed by the heads of the screws 0 Q, and moving in the line of the dotted arc X, Fig. 3.

In order to decrease the pressure between the rollers O D, the screws 1? and Rare turned in the opposite direction, whereuponthe elasticity of the rubber rollerG will push back the roller D, with its brackets.

In order that these cleaningrollers may operate eflectually, it is necessary that they press closely upon one another. The rotation is in the direction of the arrows, Fig. 3, and the line of contact of 'the rollers should be brought as closely as possible to the pickers, so that the fibers of cotton will be caught. The rollers,revo1ving with great rapidity, will not only reel ofl the cotton from the pickers and throw it toward the shield I, but also, by centrifugal force, they will keep themselves free and prevent the cotton from wrapping around them without the use of the scrapers shown in my former patent.

The rubber roller 0 should be made of sufficient elasticity to allow masses of cotton to be carried through at one part without materially disturbing the pressure of other parts, and this elasticity will also prevent injury to the seeds contained in the picked cotton.

In order to increase the yielding character of the rubber roller, cells V V, Fig. 3, may be cast in its body. By this device rubber of a cheaper grade may be used. The surface of the rubber roller should be kept as hard and smooth as possible.

The steel roller should be polished and nickelplated, to prevent rusting.

One or more pairs of these cleaning-rollers, suitably geared,may be placed upon each side of the harvester at suitable points to draw away the cotton from the pickers.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a machine for harvesting cotton, in combination with suitable picking devices, a pair of cleaning rollers arranged in contact with one another and rotated in opposite directions, and means for adjusting them to and from one another, substantially as described.

2. In a machine for harvesting cotton, in combination with a suitable picking device, a pair of cleaning-rollers arranged in contact with one another and rotated in opposite directions, means for adjusting them to and from one another, and means for adjusting one of said rollers to and from the picking device, substantially as described. I

3. In a machine for harvesting cotton, in combination with a suitable picking device, the cleaning-rollers G D, the brackets G H, the bar F, the screws P R, for adjusting the roller D to and from the roller 0, and the screws 0 Q, for adjusting said roller D to and from the picking device, substantially as described.
