COTTON GIN.

Application filed June 22,

This invention relates to cotton gins, and aims to provide a novel form of gin wherein the cotton boll willbe subjected to a thorough cleaning, so that the lint cotton may be 5 entirely removed from the boll.

Another object of the invention is to pro- Vide a gin of this character which will straighten the lint-and cause it to be pressed into engagement with thesaws in such a way that when the lint is drawn through the ribs of the gin, the lint will not be broken by the action of the saws, to the end that a better grade of lint is produced.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described 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:

The figure illustrates a vertical sectional view through a gin constructed in accordance with the invention.

Referring to the drawing in detail, the body portion of the gin is indicated generally by the reference character 5 and is in the form of a housing having a base 6.

At the upper portion of the body portion of the machine is a hopper 7 into which the cotton bolls are fed, from where the bolls pass onto the rotary brush 8 which is mounted for rotation at the base of the hopper 7.

The reference character 9 indicates a curved brush housing which is secured to the body of the gin at 10, the lower portion of the brush housing 9 being open as clearly shown by the drawing.

Gin saws indicated at 11 operate between the ribs 12 in the usual manner and are so constructed that portions of the gin saws operate within the brush housing 9 and are engaged by the rotary brush 13 which is adapted to press the material onto the saws in such a way that it will be pulled through the ribs without danger of breaking the lint.

Located adjacent to the rotary brush 8 is a stationary adjustable brush 14 having bristles 15 that sweep the teeth of the gin saw and exert pressure thereon to cause the lint to adhere to the saws. This brush 14 is hingedly connected with the brush housing and may be 1926. Serial No. 117,760.

adjusted towards the brush housing 9 by -n1eans of the winged nut 12 that operates on the bolt 14 secured to the housing 9, there bemg provided a coiled spring 13 for normally exerting an outward pressure on the brush 14.

lVithin the body portion is a substantially large rotary brush 16 having bristles 17 that clean the lint from the gin saws 11, forcing the lint outwardly through the spout 18.

Disposed directly under the brush 8 is a roll 19 that carries blades 20, and as shown, this roll 19 operates within the housing 21 that has a hopper 22 at its upper end, the hopper being disposed directly under the lower ends of the ribs 12 so that the material passing over the ribs may be discharged into the housing 21.

The reference character 23 indicates lower gin saws that are mounted on the shaft 24 in such a way that portions thereof extend into the housing 21 to receive material which is pressed against the saws by means of the blades 20.

The saws 23 operate between the lower ribs 25 to the end that lint which passes into the housing 21 will not pass outwardly with the hull, but will be carried'through the ribs and thoroughly cleaned from where it passes through the discharge spout 26.

An adjustable member 27 is pivotally supe ported at the discharge opening of the housing 21 and is controlled by means of the screw'28 and Winged nut 29, whereby the space between the free end of the adjustable member 27 and the gin saws 23 may be varied to meet various requirements.

Cooperating with the gin saws 23 is a substantially' large rotary-brush 30 which is designed to pick the lint from the saws 23 and force the same through the spout 26.

In order that material that is carried through the ribs 12 and which has been carried by the brush 16 will not be lost, a chute 31 is provided which chute has one end thereof disposed adjacent to the saws 11 and brush 16,whi1e the opposite end thereof is disposed within the hopper 22 to direct such material to the hopper 22 and into the housing 21, I

where it is reginne'd.

From the foregoing it will be obvious that due to the construction of this machine, the cotton is thoroughly ginned and all possibility of the lint passing out of the machine with the hulls, is eliminated.

It will further be noted that due to the con Struction of the'brushes and stationary .brush 14, the lint will be packed on the saws in such a way that it will not be broken in its passage through the machine, to :the end that 752111 exceptionally high grade of lint is produced.

I claim:

A cotton gin embodying a housing, a hop per at one end of the housing through which material is fed to the housing, a gin saw suported within the housing adjacent to the discharge en dof the hopper, a rotary brush operating within.thehousingand contacting with ,the gin saw to remove material therefrom, a brush housing having an open lower extremity and into which a portion of the saw extends, a rotary brush within the brush housing and disposed above the gin saw and contacting wlth the gin saw to remove ma- :terial therefrom, a depending (brush hingedly connected withthe brush housing and contacting with the gin saw at a point between the first mentioned brushes, means for adjusting the depending brush with respect to the gin saw an-danoth'er rotary brush for contacting with the gin sew adjacent to the lower edge thereof.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
