Letters Patent No. 84,392, datcd November 24, 1868.

IMPROVEMENT IN SAW COT'I'ONGFIN The Schedule refen'e to in these Letters Patent and making part of *he same.

To all whom 'it ana/y concern:

Be it known that I, XVILLIAM SU'rToN, of lVashington, in the county of lVilkes, and State of Georgia, have invented a new and improved Saw Cotton-Gin; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying dra-wings, formingr part of this specification.

This inventiou relats to a new and useful improvement in the construction of hoppers for saw cottongins, whereby the cotton fed to the machine .is acted upon equally throughout the entire gang of saws.

In the accompanying slieet of drawings- Figure 1 is a front view of my invention.

Figure 2, a plan or top view of the same.

Figure, a transverse vertical section of the same, taken in the line a; x, fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the hopper of a saw cotton-gin, B, the

, a fort-y-saw gin, the front of the hopper, c c, will be from two and a half to four inches narrower than its rear part, cl d, which adjoins the body of the gin.

The proportions of hoppers will vary with size of gins. This is shown clearly in fig. 2, and in consequen'ce of the wid-th of the hopper not being uniform, the roll of cotton within the hopper is, when the gin is in operation, constantly shifting its position, so that fresh surfaces are constantly presented to the sa-ws, and the cotton more rapidly ginned than usual, and the fibre not injured or cut.

The roll of cotton is also kept higher up in the hopper than usual, which admits of a tree discharge of the seed, much more so than usual, and the saws opera-te with less friction, as the roll of cotton doesnot extend down so deep upon them.

In cotton-gins as heretotbre constructed, the sides have been made straight, or pa 'allel with the face of lthe saws. rJ'his construction is objectionable, from the fact that the spa-cos between the outcr fm yes of the outer saws and the sides of the hopper are uniform, and very little if any cotton can find its way into them, because of the friction produced by' its contact with the sides of the hopper. As a result of this construction, the outcr saws of the gang do very little if any work.

By giving obliquity to the sides of the hopper, as lpropose, the distance between the upper edges of the saws'and the sides of the hopper is greater than the distance between the lower edges of the saws and the hoppcr, and then-.torc the cotton extending over the outer saws is readily acted upon and drawn downward.

The bars (I of the breast O are eurved, as shown in flg. 3, so as to adniit of a comparatively large number of saw-Teeth cxtending through the breast, but not so much of their snrfaces or plates; for instance, the distance from e to c is about three inches greater than usual, while from f to fit is somcn-'hat less. (See tig-3.)

This change in the rclativc positions of the saws and breast also serves to reta-in the roll of cotton in an elcvated state in the hoppcr, and to facilitate the operation of ginning in au eminent degree.

I claiin as new, and desire to secure b y Letters Patent- The hopper A, constructed as described, with its sides inclined, for the purpose of supplying the cotton to all the saws cqnally, as herein shown and described.
