COTTON-GIN.

SPECIFICATION forming part Of Letters Patent NO. 242,763, dated June 14, 1881.

Application filed April'Q, 1881. (N model.)

To all whom it may concern i Be it known that I, VALENTINE K. EDGAR, of Chico, in the county of Wise and State of Texas, have invented certain new and useful Improvements in Cotton-Gins; andl do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to an improvement in cotton-gins; and it consists in the features of construction and combination hereinafter fully I 5 described, and particularly pointed out in the claims. In the 'drawin gs, Figure l is a side elevation of the machine embodying my improvement, and Fig. 2 is alongitudinal section taken on a vertical plane.

A indicates the frame of the gin-stand, and B the saw-shaft. The usual gin-saws will be provided, and also the usual rotary brush which takes the cotton from the saws.

0 indicates an inclined endless belt of fine wire-gauze, upon which the cotton is carried up to the condenser, the sand and dirt being sifted through this belt. 7 r

The condenser is formed by a roller, D, arranged just above the upper roller, E, around which the endless wire-gauze belt travels, and below said roller E is arranged arotary wiper, F. Motion is transmitted to these rollers and the wiper by means of a worm-gear, Gr, upon the saw-shaft, and a shaft, H, having at one end a gear, I, engaging said worm-gear, and its remaining end a gear, K, which intermeshes with a larger bevel-gear, L, upon the shaft of the roller E, around which the endless belt.

of bat without additional devices; but when said roller is small and light spring-bearings can be employed for its journals.

The wire-gauze or wire-cloth band is bound along its edges with strips R of oil-cloth or leather, so that the band will fit the box or case in order to keep the air from exhausting near the edge, which would otherwise cause the cotton to get in around the edges of the wire-cloth. The upper band-roller is provided with longitudinal channels, and the endless band is provided with slats S, properly spaced,

so as to come into said channels during operation. I 1

I am aware that a rotary wire-gauze cylinder has been employed in a cotton-gin but I find far better results are obtained by the use of the Wire-cloth endless band herein illustrated the cotton being cleaned better by means of the long belt, and the lint is laid smoother 7o and straighter thereon; also, the draft of the brush will not be obstructed, there being suffi cient space for the exhaust through the wiregauze.

What I claim, and desire to secure by Lot ters Patent, is

1. Ina cotton-gin, the endless wire-gauze band or apron, bound at its sides with strips R of flexible material, such as leather, as herein described, for the purpose set forth.

2. In a cotton-gin, the endless wire-gauze band C, bound at its edges and provided on its inner side with slats, in combination with the saw-shaft, the condenser-roller D, and the upper roller, E, around which the band passes, 8 5 provided with longitudinal channels, as specified.

3. The combination, in a cotton-gin constructed substantially as described, of the endmy own I have hereto affixed my signature in 5 presence of two witnesses.
