l GIN ATTACHMENT.

.Application filed July 11, 1921. SerialNd. 483,854.

1 '0 all 10 how it may concern I Be it known that I, CLAUDE A. Hoo'roN, a citizen of the United States, residing at Sherman, Grayson County, Texas, have invented a certain new and useful Improvement in Gin Attachments, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to Which it appertains to make and use the same.

My invention relates to cotton gins. More particularly it is an attachment for cotton ins for the purpose of moving and regulating the feeding of cotton to the gin and the ejection of refuse, hulls and chaff.

In the operation of the usual types of cotton gins, especially where the cotton is holly, or contains many hulls or burrs, it is necessary to maintain attendants at the gins whose duty it is to see to the cleaning of the gin of this waste at regular intervals. To do this the gin breast in front of the gin saws must be swung out sufhciently for the hulls and burrs to drop out and then closed again. When the" gin breast'is opened the feedingof cotton to the gin must be checked until the gin is again closed. The attendant usually does this by hand. An obstruction is placed at the mouth of the chute which feeds the cotton to the gin and the gin breastis then swung open to drop out the Waste. When the gin is again closed, the feeding chute is opened and the ginning again proceeds.

The object of my invention is to provide a mechanism, operated in connection with the gin itself, which will, at regular inter.

"als, close the feeder, open the gin breast and discharge the hulls and waste and again close the gin and open the feeder, v A further purpose is to do away with the necessity of some of the attendants at the gins by performing the process of dis charging hulls, etc., from the gin automatically, without the necessity of manual operation.

Further objects and advantages will be clear from the description which follows in which a preferred embodiment of my invention is disclosed. ularly in the combination and relation of parts, and various obvious changes may be made therein without departing from the The invention liespartic- 'ing rod 15;

numerals of reference are applied-to like parts throughout the several views: Fig. 1 IS a perspective view of a gin stand with my invention applied thereto. Fig. 2 is a perspective view of the operating mechanlsm of my device. Fig. 3 is broken view showing the device in side elevation, and Fig. 4C is another perspective view thereof.

In the drawing, the numeral 1 designates the cleaner, having feeding chute '2 thereon to conduct the cotton to the gin 3. At the front or breast of the gin 3 is a door at conforming in shape to the gin breast. It

is hence of somewhat irregular shape and' I, of the gin and interfere with the proper actlon'of the gin. It is then necessary to open the ,door' l, swinging it out to the dotted line position of Fig. 3 to allow the hulls to drop out. lVhile this is done the cotton from the feeder must be. shut off by closing the opening 6 leading therefrom.

These operations areperformed by means of my invention; 'The opening 6 of the feeding 'chute is provided With a door or valve 7 connected at one of its side edges to a rod 8 pivoted to swing in forked brackets 9, one at each side of the mouth of the chute.

This door is held normally in open position by means of a weighted lever 10 fixed to the rod 8 and extending rearwardly with" i a slight upward inclination as shown' in Fig. l. The lever is maintained in this position by means of a connecting rod 11 pivotally attached to the said lever at a. point 12 spaced a short distance from the lower end of the lever. The other end of the connecting rod 11 is supported on the" outer end of an operating lever to which said connecting rod is detachably secured;

To raise the breast door tof the gima' laterally extending bracket 14 on the breast door is provided with an opening therein to which is detachably secured a connect This rod extends backwardly and upwardly and is connected at its other end to an operating lever 16'. The rod-is inserted in an opening in the said operating lever and is secured against removal by a cotter pin or some other detachable means.

The operating levers l3 and 16 are actuated by the mechanism shown best in Fig. 2. This mechanism is housed in a box 17. The housing 17 has a central upright shaft 18 therein upon which is mounted a gear wheel. Said wheel is adapted to be operated by a worm gear 20, formed on a transverse shaft 21 journalled in the box 17. The outer end of this shaft has thereon a pulley which may be operatively connected by means of a belt 23 to a smaller pulley 2 1- on a shaft of the cleaner 1.

The two operating levers 13 and 16 are pivoted at one side of the housing on a pin This pin is on that side of the box 17 away from the gin stand 3. A slot 26 in the lower half of the housing n'ovides a guide for the lower lever 16. The upper lever. moves in a slot 27 in the lower face of the upper half of the housing which is removable so as to form a cover for the mechanism. v i

The gear wheel 19 is mounted so as to set in a horizontal position midway between the two operating levers. On the upper face of the wheel and closely adjacent the outer edge are a plurality of evenly spaced camv blocks 28. The outer face of each of these cam blocks is rounded to contact with the upper lever 13 as the gear wheel rotates.

On the lower face of the wheel are a like number of rollers 29 shown in dotted lines in Fig. 2. These rollers are slightly behind the cams 28, as the wheel rotates, and are positioned to bear against the lever 16 and throw it over slightly after the upper lever is operated and, because of its shorter surface of contact with the lever, will also allow it to swing back sooner than can the upper operating lever.

The housing is supported by any convenient means such as a bracket as may be most desirable, at a point near the gin stand. The rotation of the pulley 22 by means of the belt, or any other convenient means, will cause the rotation of the wheel '19 in a clockwise direction as viewed in Fig. 2. As the wheel rotates the can] 28 will come in contact with the upper lever 13 first. This will act to shove it forward into the position shown in Fig. 41-. This motion of the lever will act through the connecting rod 11 to throw the weighted lever 10 into raised position and close the door or valve 7 as shown in Fig. 4.

The roller 29 on the lower face of the gear wheel will then strike the lower operating lever 16 and force it forward to the position shown in Fig. 4 and thus throw the rod 15 and the breast door 4 forwardly so as to allow the waste to be discharged.

The continued rotation of the wheel 1!) will. bring the roller 29 out of contact with the lever 16 and the weight of the door 4L will cause it to drop back and throw the lever 16 into its rearward position. The cam 28 will then pass the lever 13 allowing the weight 10 to drop and open the door 7 and throw the lever 13 back.

The continued rotation of the gear wheel 19 will shortly brin another set of cam and roller into engagement with the levers 13and l6 and repeat this operation. The proper spacing of the cams and the timing of the gear will serve to close the valve 7 and shut off the feed of the cotton and to then open the door to the gin breast and discharge the hulls, close this door and then open valve 7 and feed the cotton again to the gin and to repeat this operation regularly at the proper intervals of time.

As will be noted, this device is simple and positive in its action and is not liable to easily get out of order. It may quickly be attached or detached from its operative position. Thus, where the cotton is clean, and the device unnecessary, the belt may be removed, the valve 7 may be lifted from the brackets 9, and the connecting rod 11 detached from the operating lever 13. The connecting rod 15 may also be quickly cletached and removed. The gin may then be run as usual. If a poor quality of bolly cotton is again to be ginned, the device may be as quickly installed and operated. It may easily be set up for operation on any ordinary type of gin stand with little expense.

Having thus described my invention, the further advantages and objects of which will be clear to one skilled in the art, what I claim as new and desire to protect by Letters Patent is: I
