PORTER MORRISON, OF ATHENS, TEXAS.

corroN-onv.

To all whom it may concern:

Be it known that .I, PORTER MORRISON, a citizen of the United States, residing at Athens, in the county of Henderson and State of Texas, have invented new and useful Improvements in Cotton-Grins, of which the following is a specification.

This invention relates to cotton gins, and the principal object of the invention is to produce a cotton gin of small dimensions which may be conveniently operated by hand, but which shall be entirely effective for the purpose of. removing the lint from seed that it is desired to save for propagating purposes.

A further object of the invention is to produce a simple and convenient gin of small dimensions which while entirely efiective to remove the lint will not be liable to injure the seed.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described I and particularly pointed out in the claim.

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

In the drawings,-Figure 1 is a side elevation of a cotton gin constructed in accordance with the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a front end view. Fig. 4 is a transverse sectional view taken in advance of the rotary brush and looking in the direction of said brush. Fig. 5 is a longitudinal sectional view.

Corresponding parts in the several figures are denoted by like characters of reference.

The casing of the improved gin is of substantially rectangular shape, and said casing has been shown in the drawings as being composed of plates or side members 5, 5 and front and rear plates 6, 7, said plates being formed of sheet metal, such as steel plate of suitable gage, and the end members being terminally bent to produce flanges 8 for the passage of bolts 9, whereby said end members are connected with the side members.

A simple, light and efficient casing of great Specification of Letters Patent.

Patented Oct. 20, 1914. Serial No. 809,553.

strength is in this manner produced. The side plates 5 are provided with apertures for the passage of the several shafts to be hereinafter mentioned, and said apertures are exteriorly reinforced by journal boxes 10 preferably of cast iron, said boxes being mounted in position by means of bolts, rivets or other suitable fastening devices, not specifically indicated. The main driving shaft 11 has at one end a crank 12 whereby it may be rotated. The other end of the shaft 11 carries a spur wheel 13 meshing with a pinion 14 on a counter shaft 15, which latter also carries a spur wheel 16 for the purpose of transmitting motion at accelerated speed to the saw shaft 17 which carries a pinion 18 meshing with the spur wheel 16. The latter also meshes with a transmission pinion 19 which in turn meshes with a pinion 20 on the brush shaft 21 for the purpose of rotating the latter in the proper direction.

The saw shaft 17 carries the saws 22 which partially project through slots 23 in an inclined breast plate 24 which in this instance constitutes the bottom of the feed hopper 25, which latter is bounded by the two side plates 5 and the front plate 6 of the casing, together with an upward vertical extension 26 of the breast plate 24. Secured on the front plate 6 is a deflector 27 which extends obliquely in a downward and rearward direction toward that portion of the saws which projects through the slots 23.

The shaft 21 carries the cylindrical brush 28 which is in peripheral engagement with the saws for the purpose of removing the lint from the latter. A comb 29 is also employed for the purpose of detaching the lint from the brush.

While the operation of this gin does not differ in any essential detail from machine gins of well known construction, it will be seen that T have provided a very compact and effective device of small dimensions which has been found extremely efiective for the purpose of detaching the lint from the seeds. The device may be manufactured and supplied at a cost which will permit acquisition by the individual cotton grower, even if operating on a comparatively small scale.

tion is practically impossible when the entire crop is ginned at the large gin house, andit is believed that by the use of this simple machine, the cotton culture may be greatly benefited. v

Having thus described the inventiom what is claimed as new, is

, A miniature cotton gin for saving seeds for propagation, the same COmPriSing a rect'angular casing having side members and 'end members formed 0]": sheet metal, said end members being provided with flanges abutting on the side members and bolted thereon, the front end member having a clown- Wardly and rearwardly extending deflector, an inclined slotted breast plate positioned in rear of the deflector and having upwardly and downwardly extending portions bolted upon the side members, cast metal boxes riveted on the sheet metal side members and affording bearings for a saw carrying shaft and a brush carrying shaft, gearing for transmitting motion between said shafts and for driving and properly speeding the same, and a comb fixed on the rear end wall of the casing and extending in the direction of the rotary brush which it engages.

In testimony whereof I ailix my signature in presence of two witnesses.

PORTER MORRISON.
