GIN RIB.

Application filed September 17, 1921. Serial No. 501,394.

This invention relates to cotton gins and more particularly to the means for increasing the ginning capacity of the. same.

An important object is to provide a cotton gin having a plurality of revolving ribs which move between the gin saws and thereby double the ginning capacity of the gin.

Further the invention aims to provide a rotary rib for gin saws which does not affeet the usual operation of the gin and which on the other hand will substantially increase the cleaning capacity of the machine.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a detail vertical sectional view through a gin having the improved saw cleaning means.

Figure 2 is a detail transverse sectional view through the brush of the gin, the view illustrating the saw cleaning means. i

Figure 3 is a side elevation of one of the cleaning elements detached.

In the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 5 generally designates a gin of the usual construction and which is provided with a plurality of spaced parallel saws 6 having their edges formed with teeth 7 adapted for ginning cotton in the usual manner. A plurality of stationary gin ribs 8 are arranged between the disk-shaped saw blades 6 and are secured at their ends to the frame as indicated at 10. The usual brush 12 is arranged rearwardly of the saws 6 and is provided with radial bristles 14 which contact with the teeth 7 and thereby remove the cotton from the same.

In operation the stationary ribs are located on opposite sides of the saws 6 and the detaching of the cotton fibre takes place at the point where the rib heads 23 are in ginningengagement with the several saws.

, In order to increase the ginning capacity.

of the gin I have provided a plurality of rotary members 15 each of whichyis provided with a plurality of radially arrangedribs 22. The rotary members which are generally designated by the numeral 15 extend ,j

betweenthe gin sawsG and thereby increase the ginning capacity of the gin to a substantial extent. The ginning capacity of the saws is approximately doubled by the use of the improved revolving rib which as previously stated and which as illustrated in Figure 1 extends between the saws.

Each rotary member 15 is provided with a hub 16 mounted upon a shaft 17 and keyed or otherwise secured thereto. The shaft 17 is journaled to the ends of the breast 18 of the gin and is provided with a pulley 19 operated by a belt 20 from any suitable source of power.

It will be seen that the terminal portions of the radially arranged ribs 22 are provided at their ends with laterally project ing enlargements 23 which move between the saws and thereby double the ginning capacity.

In operation the speed of the revolving ribs is about 112 revolutions while the speed of the saws is about e00 revolutions and by reference to Figure 1 it will be observed that theadjacent portions of the revolving ribs and saws rotate in the same direction.

The purpose ofthe revolving ribs is to turn the roll of cotton in the gin breast.

In the cotton gins now in use, the saws pull the cotton against the stationary ribs and this sudden jerk causes the fiber to be broken. I t

In. accordance with this invention the ribs rotate with the saws, but at a different speed and consequently the fiber is not torn.

In use the cotton may be fed into the hollow breast 175 and the picker roller176 feeds the cotton to the saws which gradually pull the cotton up into the gin breast and through the huller ribs'178. This removes the hulls if any from the cotton.

The clean cotton may be fed'in at the top of the gin breast. It is thus seen that the into the breast.

With reference to the foregoing description taken in connection with the accom- ,.panying drawing, it will be see-n that the increase the cutting capacity and to prevent napping of the cotton as well as to gin with a slacker roll.

I claim I 1. The combination witha gin having a plurality of gin saws, of stationary ribs arrangedbetween said saws, and rotatable r'ibs'eXtended between said saws.

2. The combination'with -agin having a plurality of gin saws, of stationary ribs arranged between said saws, rotatable ribs 7 extended between said saws, saidrotatable ribs being provided with enlarged heads 3'. The combination with a plurality of gin" saws, of stationary ribs extended between said saws, and rotatable ribs extendedb'etween said saws adjacent" said stationary ribs and provided with radially arranged members.
