l Application le'd September My invention relates to cotton gins and more particularly to means for preventing` the choking of the cotton about the ribsof the gin; and the object is to pro-vide revolving ribs and other ribs which cooperate with the' y revolving ribs for preventing the choking of the ribs and saws and which will reduce the power required to run the gin mechanism and which will make it possible for the gin to run much faster because the improvements reduce friction by preventing the cotton from crowding and rubbing against .the saws and ribs7 and for these reasons the improvementsmake the operation of the gin more economical'. Another advantage'is that the fire hazard is reduced by preventing friction of the saws and ribs against the cotton. It has been dis-r covered that the cause of the fire in many instances is the friction of thecotton and saws and the particular'location of the trouble is the cotton that becomes hung on the ribs and bears against the saws on-the underside of the ribs, that is, after the saw teeth pass the ribs, the saws rub against the cotton that is clinging to the ribs and this is where the fire -originates. The obj ect is to provide, in addition to the ribs heretofore provided, revolving ribs that will throw the cotton vroll back away from the points where the saws pass through the stationary ribs and to change the shapes of the stationary ribs to cooperate with the revolving ribs. `Another improvement is a vdofling roller for coopcrating` withv the revolving ribsgvhich will aid in forming the roll in the roll boX. Other objects and advantages will be fully explained in the following description, Vand the invention will be more particularly pointed out in the claims.

indicate the same eral views.

A gin stand 20 of ordinary'type is shown i in the rdrawings provided with 'the' improvements and saws and a brush drum. rIhe gin has the usual. roll bon which 1s a space above are similarto the lower parts of the usual ginv ribs, but theribs have acuate 4dividers 8 which cooperate with the saws 2 and t-he revolving' ribs 10 and the doiing roller l5 .to forma roll of cotton in the roll box.v The dividers 8 conform approximately to the curvature of the revolving ribs 10 and the ribs have curved portions 9 which stand in closeproximity to the revolving ribs l() and the ribs are attached to the back side of the gin rail 7. The object of this construction and arrangement is to locate the parts of the ribs through whichthe saws pass as far away as practical from the roll in the roll boX. The saws 2 pass through the ribs 10 `at approximately the parts yl1 of the ribs 5, the saws having already passed through the ribsslO.

`The dividers 8 and the rolling ribs l0 preventthe crowding ofthcseed and unginned cotton at the points 1l of theribs 5. There are advantages in this provision because the TvWENTY-FORTIETHS TO C. R. IPRESSLEY, ALL FORT WORTH, n

parts throughout the sevillle O'lIl SJWS 2 21. blvllSh kCll'LlHl r?) and Other ceV lint `is more quicklyremoved from'the seed due to the non-crowding or packing of the cotton and seed against the ribs at parts 1l l and the lint is more easily removed from the saws after the saws leave the ribsv at Vparts ll. This is the danger point of lire and the lire hazard is removed by the construction land arrangement shown. VThere'ason for this'is that no lint cotton hangs on .the ribs to rub against the sides of the saws. The danger to be removed was the rubbing ofv the saws against the'lint cotton which was clinging to the ribs. This rubbing created enough friction to cause ignition. Y

`The saws 2 run as the arrow head shows in Fig. 3, which direction is clockwise. The revolving ribs are mounted to run in the saine direction, that is, clockwise. The ribs 10V are rigid with a shaft 12 and the shaft 12 is journaled in heads 13 and 111 and these heads are provided with journal boxes or bearings 15 which are integral therewith and tl e boxes 15 support antilrrction bearings 16. A cap 17 holds the bearings 1G in place. l A doiiing roller 18 is provided with a shaft 19 which is journaled in bearings 2O which are integral with the heads v13 and 11i and antitriction bearings 21 are provided lor the shaft 19 and these bearings are held in place by a cap 17.

Vtlhat I claim is,`-

1. In a cotton gin provided with a gang of saws and a, roll box; a traine tor the gin7 a swinging :traine hingedly yconnected thereto,

heads attached to the lower part of saidv swinging traine and to the upper part thereof, bearings torined on the outsides of said heads, revolving ribs provided with a. shaft journaled in saidbearings, a clotting roller providedwith a shaft jo'urnaled in bearings on said head, ribs attached at their lower ends to said swinging traine and provided with Ycurved dividers extended partly in front ot said revolving ribs and said ribs being curved under said revolving ribs and then upwardly and attached to the rear side of said swinging traine. l

In a. cotton gin provided with a gang of saws and ra roll box and a traine; a swinging traine including upper and lower rails hingedly connected to the gin l'raine7 bearing heads attached tol said upper and lower rails, a doitlng roller and revolving ribs journaled inl-said bearingl heads, `and ribs attached to said rails and positioned between said saws p tioned between said saws and attached tosaid upper and lower rails7 and means forspacingY the leaving` passage of said saws troni said ribs from they roll termed in saidroll box Consisting' lol saidv revolving ribs, curved dividers formed on said stationary ribs and projec'ing slightly in front of said revolvingribs, and Curved nieinbers foi-ined ol' said sta tionary ribs and curved part-ly about said revolving ribs.
