Specicaton of Letters Patent.

Application med March 18, 1920. Serial No. 366,797.

To f/ZZ whom z'v' may concern.'

Be it known that I. Renner H. MrLAM, a citizen of the United States. residing4 at Helena. in the county ot Phillips and State of Arkansas. have invented a new and useful Cotton-Gin, ot which the following is a specification.

This invention relates 'to grinning' machines, and it is the main object of the invention to provide means to permit of a free and unobstructed passage of the cotton from the roll box. to the doiier. thus eliminatinsz the possibility of the lone staple cotton becoming broken, in its passage 'from the roll box.

A further object of the invention is to provide a clearance between the upper ends ot the ribs. and the lower edge of the rear wall ot the roll box to permit the cotton to pass therefrom. the seeds beine removed by their contact with the lower edge of the rear wall ot the roll box.

With the foregoing and other obiects in view which will appear as the description proceeds, the invention resides in the combination and arrangements of parts and in the details of construction hereinafter de' scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a vertical section through a cotton .qin constructed in accordance with the present invention. and

Fig. 2 illustrates a fragmental front ele vational View. the same beine' partly broken away to illustrate the clearance formed between the upper ends of the ribs, and the roll box.

Referring' to the drawing in detail, the reference character 5 designates the rear wall of the trame of the machine which extends upwardly terminating at a point an appreciable distance above the upper edge ot the gin saws indicated at 6. and as shown, the upper end of the rear wall supports the rear wall 7 of the roll box.

The gin saws 6 are arranged in spaced relation with each other in the usual manner,

the same being supported on the power shaft 8, which is shown as extending through the saw. the shaft being keyed or otherwise secured to the saws 6. so that rotary movement oi the shaft produces a relative movement of the gin saws.

An angrul ar supportinc1r bar 9 forms a part of the gin frame. and this bar 9 supports a securing bar 10. to which the lower ends of the ribs 11 are secured. by vmeans of the screws 12 passing through suitable openings provided in one end of each ot' the ribs.

The front wall 13 of the roll box is curved in the usual manner, the lower edge of which has connection with the securing beam 14 in any suitable manner. which beam 14 also provides means for supportme; the upper portion of the ribs 11, the ribs 11 beine' shown as haviner connection with the beam 14 through the lateral extensitkins 15, which form a part of each of the ri Is.

Forming a part of each of the ribs, are lateral ribs 16 which extend from a point adiacent to the upper end of each of the ribs. the upper end terminating' at a point adiacent to the base of the teeth of the saws, and cooperate with the lower edge 17 of the roll box. to provide a clearance 18 to permit the cotton to have an unobstructed passage from the roll box to the dofier. i

In the operation of the device, cotton is carried into the roll box, in the usual manner. where the same is caused to revolve within the roll box, the saws bringing the cotton through the clearance between the upper ends of the ribs 11 and the lower edge of the rear wall of the roll box. the lower edge 19 contacting with the seeds to dislodge the same from the cotton, where the seed pass on to the lateral rib 16, and are carried off in the usual manner.

From the foregoing it will be seen that lone; staple cotton is carried through the space between the upper ends of the ribs and roll box to the end that the same is unbroken and tree of seed.

Having thus described the invention, vwhat I claim as new is In a cotton gin, a frame. a roll box Supported by the frame, a plurality of ,ein saws operating under the roll box, a pluralty of ribs disposed between the saws, In testimony that I claim the foregoing each of said ribs having a lateral extension as my own, I have hereto axed my signaprovdng means to secure the ribs to the ture inthe presence of two Witnesses.

roll box, dnd said ribs being constructed to ROBERT H. MILAM. provide at clearance between the upper ends Witnesses :V

thereof and the roll box, to permit the pas. IVY E. SIMPSON,

sage of cotton from the roll box. J. R. PATTISON.
