Claims.

My invention relates to attachments for cotton gins for use in ginning cotton.

The device has particular application to means for preventing the motes in the cotton from contaminating the lint. In the ginning of cotton the lint is drawn around by the saws and delivered to the suction nozzle by means of which the lint is removed from the saws. If the lint is accompanied by motes, as is very common 1 especially in bolly cotton, the motes are liable to be thrown off by the saw and sucked back into the outlet nozzle. To prevent-this, a mote board is employed.

It is an object of my invention to provide a mote board which is adapted to conform closely to the curvature of the gin saws so as to better prevent the drawing of the motes back into the lint.

It is a further object of the invention to provide a mote board having a rounded upper edge upon which the cotton may be easily removed so as not to catch on the board and clog the space between the board and the saw.

It is a further object of the invention to be able to adjust the position of the mote board relative to the saw to accommodate the board for different qualities of cotton which is ginned.

It is also an object to provide means whereby a material which tends to lodge about the mote board can be removed therefrom during the operation of the gin without danger to the operator.

I desire to provide a brush which may be swung by the operator across the mote board in such manner as to dislodge any material tending to clog the same.

In the drawing herewith I have shown a central vertical section through a gin upon which my invention has been employed.

The gin illustrated in the drawing is intended to represent the usual gin employed in ginning operations. There is a frame 2, supported upon legs I and having an outer housing 3 protecting the interior working parts. Mounted in the frame is a shaft 4 upon which the gin saws 5 are mounted, said shaft having hearings in the side portions of the frame and rotatable by the usual means in the counterclockwise direction indicated by the arrow.

The cotton is fed to the gin saws through a gin breast 6 and is carried into contact with the gin saws by the picker roll 1. Below the picker roll is a hull conveyer 8, which carries from the gin breast the hulls from which the cotton lint has been removed.

The cotton is caught by the gin saws and The cotton lint carried by the saws past the 10 ginning ribs is moved downwardly past the air nozzle l4 into the suction tube l5 through which it is carried from the gin. The motes which are carried around with the lint by the gin saws are thrown off to the rear into the chamber l6 and dropped therefrom into the trough I 1, from which they are carried out of the gin by the mote conveyer l8.

My invention is in the provision of a mote H board I9 to the rear of the gin saw and mounted 20 at the upper end of the nozzle l4 so as to prevent motes thrown from the gin saw from being sucked back in through the action of the air nozzle. Mote boards have previously been mounted adjacent gin saws in somewhat this position but they are not adapted to lie closely adjacent the saw and to that extent are somewhat ineificient. In order to conform to the curvature of the saw I have curved the mote board I9 so that its upper end and the inner surface may be close to the saw without interfering with the passage of the lint downwardly to the discharge chute. As shown in the drawing, this mote board is mounted upon a rod 20, which extends through the side walls of the housing and the mote board is thereby adapted to be swung toward and away from the gin saws.

The swinging of the mote board is accomplished by means of a crank arm 2| mounted at one end of the rod 20 and extending upwardly for connection at 22 with an operating lever 23, which acts as a pull rod to move said crank arm. On the lower side of the lever 23 is a series of notches 24 which are adapted to receive a plate 26 on the frame of the gin and to hold the lever in any adjusted position. Said lever is formed with a handle 21 extending outside the gin and within reach of the operator. It will be noted that by use of this lever the mote board may be swung to different adjusted positions relative to 50 the saw.

It is also to be noted that the upper edge 28 is rounded so as to prevent stringy cotton from engaging thereon and thus to some extent preventing the cotton from lodging around the up- 55 per end of themote board and between the same and the saw. By the use of this type of mote board the passage of motes downwardly with the lint is largely avoided.

In cotton having stringy material therein it is practically impossible to prevent some engaging of the cotton over the upper end of the mote board and furthermore with the curved outer surface shown in my construction of the board, motes may engage on the rearward side of the board in the mote box. In order to avoid this and prevent the necessity of having to remove the material from the board by hand, I have provided a brush for cleaning the mote board when necessary. This brush will now be described.

I form a cross shaft 29 to the rear of the mote box and upon this shaft is supported a pair of swinging arms 30, one at each end of the box. Toward the inner ends of these arms I mount brushes 3|, which are held upon a cross bar 32 by means of a plate 33. It will be understood that the bristles are clamped in a recess on the arm and are held in position projecting forwardly as shown in the drawing. Mounted also upon the shaft 29 is a pair of crank arms 34 and 35, which extend upwardly and to the rear of the shaft. On the crank arms 34 I connect at 36 a pull rod 31, which extends forwardly to a position outside of the gin where it is provided with a handle 38 by which it can be operated to swing the shaft 29 and with it the brush. Upon the arm 35 I connect a tension spring 39, which extends rearwardly and is secured at 40 to the frame of the gin. This spring tends to hold the shaft in position with the brush elevated as shown in full lines in the drawing.

The brush, together with the arms upon which they are mounted is spaced forwardly so that when the arms are swung downwardly through the manipulation of the rod 31 the brush will be swung across the rearward side of the mote board l9 when said mote board is in its forward position. When the pull rod is released the spring 39 will swing the arms with the brush back upwardly, again moving across the mote board so as to sweep therefrom any material clogging around the board.

By means of this brush I am enabled to clear material from the mote board without danger to the operator. The usual method employed in clearing material from the board involves the use of a wire or stick which must be inserted by the operator in through the side of the housing to scrape the material from the board. This is an exceedingly dangerous operation and may involve serious injury to the hands of the operator. With my brush, however, it will be possible to clean the board quickly and conveniently without any danger whatever to the operator of the gll'l.

The advantages of my improved mote board and the means employed for cleaning the same enable me to conform the board to the shape of the gin cylinders so as to prevent the motes from entering with the lint without tending to clog the saws, and further allows the easy and ready removal of the material from the board in case there is a tendency to clog.

What is claimed is:

1. In a cotton' gin the combination of a mote board positioned adjacent the gin saws, and means including a swinging frame within the gin, a brush on said frame, said frame being operable from the exterior of the gin to remove materials clinging to said mote board.

2. In a cotton gin the combination of a mote board positioned adjacent the gin saws, and means within the gin and manually operable from the exterior of the gin to be swung upwardly to remove materials clinging to said mote board, said means including a brush adapted for reciprocatory movement past said board.

3. In a cotton gin having gin saws and a mote board, means to displace material clinging to said board, said means including a spring actuated lever to brush by the mote board while the gin is in operation.

4. In a cotton gin a cleaner for mote boards comprising means to move past the mote board to clean off the material clinging thereto, a handle to actuate said means, and a spring means to normally hold said first means in an inoperative position.

5. In a cotton gin having gin saws, the combination of a mote board positioned closely adjacent the rearward side of said saws in uniform- 1y spaced relation thereto, and means operable to be moved upwardly along the side of said board and brush material from the upper end of said board when desired, said means including a shaft, arms thereon, a brush on said arms, and a crank on said shaft.
