GIN-RIB.

Specification of Letters Patent.

Patented July 31, 1906.

Application filed December 13, 1905. Serial No; 291,605.

1'0 and w/wm, it may concern:

Be it known that I, FRANcrs DANIEL ALL- GOOD, a citizen of the United States, residing at Thurmon, in the parish of Claiborne and State of Louisiana, have invented a new and useful Gin-Rib, of which the following is a specification.

This invention relates to ribs for cottongins; and the object of the invention is to prevent the ribs from springing apart or spreading at the points where the teeth of the saws pass between them, thus causing the cotton to become packed between the ribs, and thereby not only straining and injuring the latter, but also permitting the passage of seeds and foreign material which should be separated from the staple.

Further objects of the invention are to simplify and improve the construction and operation of the ribs.

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, 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 invention may be made when desired.

In the drawings, Figure 1 is a vertical sectional view taken through the breast of a gin formed with the improved ribs of this invention. Fig. 2 is a plan view showing a portion of the breast. Fig. 3 is a perspective vigw showing the upper end of one of the r1 s.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

1 2 are the cross-bars upon which a plurality of ribs 3 3 are mounted in the usual manner, as by means of screws 4, to form the breast of the gin.

5 is the shaft carrying the saws 6 6.

The ribs are provided near their upper ends and closely adjacent to the points Where the teeth of the saws pass between them with laterally-extending lugs 7 7, having square-faced vertical ends 8, that. abut upon each other, so as to positively prevent the ribs from springing laterally or from being spread in a lateral direction. The under sides or edges of these lugs present shoulders 9 at right angles to the sides of the ribs, so that the passage of the fiber between the ribs will not be obstructed. The under sides 9 of the lugs 7 are located in a planeparalleltoa tangent to the periphery of the saws 6. The upper edges of the lugs 7 may be beveled, as shown at 10.

By reason of the construction described springing or spreading of the ribs is positively prevented, and clogging or packing of the gin-breast is thus practically prevented, thus not only preventing the passage of seeds and trash between the ribs, but also preventing the injury to the latter resulting from the springing or spreading and greatly increasing the life of the rib.

Having thus described the invention, What is claimed is- In a cotton-gin having circular gin-saws,

ribs located between the saws and having laterally-extending lugs, said lugs having square-faced vertical ends, the ends of the lugs of one rib abutting against the ends of the lugs of the adjacent ribs, the under edges of said lugs being located in a plane parallel to a tangent to the periphery of the saws.

In testimony that I claim the foregoing as my own I have hereto afl'iXed my signature in the presence of two Witnesses.

FRANCIS DANIEL ALLGOOD.
