COTTON GIN.

Application filed. November 20, 1920.

To all 'whom t may concern:

Be it known that we, CHARLES L. Dionne- MAN and 'WILLIAM E. CUMMINGs, citizens of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful lmn provements in a Cotton Gin, of which the following is a specification.

This invention relates to new and useful improvements in a cotton gin.

One object of the invention is to provide a gin whereby lint cotton may be ginned or stripped from the seed with little injury to the lint, and the seed and lint then discharged separately from the gin.

Another object of the invention is to provide a gin which is of simple construction and may be cheaply and easily manufactured as well as easily operated.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying draw ings, wherein z- Figure l is a plan view of the gin partly broken away, and

Figure 2 is a vertical sectional view of the gin.

Referring now more particularly to the drawings, the numeral l indicates a suitable frame-work to which the stationary circular casing 2 is secured by means of the bolts 3. The bottom of this casing is flat but the top is formed into a funnel et. Within the casing there is an annular rotary turbine 5 which is frusto-conical in general contour and has an open center. This turbine has radiating spokes, as shown by which it is fixed to the inner end of a hollow shaft 6 which works in a central bearing in the bottom of the casing and whose lower end has a beveled gear wheel 7 fixed thereto which is in mesh with a similar gear wheel 8 which is fixed on the drive shaft 9. ylhe turbine is somewhat less in diameter than the casing and has the projecting wings or blades l0 spaced apart which are enclosed by the casing and which sweep around the casing, as the turbine rotates, forming in effect a fan. The conical face of the turbine is exposed through the hopper d and is provided with an abrading surface ll, preferably consisting of spiraled corrugations.

fieri-a1 No. 425,392.

surface ll. rilhe operative faces, or edges of Vthese blades are reverse y spiraled with rea0 spect to the corrugations of the face ll.

Extending rearwardly from each blade there is a fan shaped housing l5 which lies close against the surface ll and. whose outer ends are secured to the inner margin of the hopper il.

ln operation, the turbine is driven at a rapid rate of speed and the seed cotton is fed down through the hopper falling onto the abrading surface ll of the turbine ahead of the stripper blades. is the turbine rotates the seed will be arrested by said blades and the suction of tl fans will strip the lint from the seed, said seed being retarded by the stripper blades. The corrugations of the abrading surface cooperating with the blades will cause the seed to gradually travel up the abrading surface 1i and gradually work into the open center i3, of said turbine and fall then into the casing, from which the seed are then discharged by any conventional type of conveyor.

The suction of the fans 10 will strip the lint from the seed and draw the cotton into the casing 2 and it will be discharged by the fans out through the discharge spout 14.

What we claim is:

l. A cotton gin, including a casing whose upper side is formed into a hopper, a frustoconical shaped turbine therein having an abrading surface which is exposed through said hopper, radiating blades projecting from said turbine and spaced apart there around, stripper blades fined to the casing and disposed to cc-operate with the abrading surface to arrest the seed as the turbine is rotated and separate outlets from the gin for the seed and lint respectively.

2. A cotton gin, including a fixed circular casing whose upper side is formed into a hopper, a frusto-ccnical shaped turbine therein having an abrading surface which is exposed through said hopper, means for rotating said turbine, radiating blades fixed tc the turbine and spaced apart therearound, stripper blades fixed to the casing and disposed to cooperate with said abrading surface and means for rotating `the turbine.

3. A cotton gin including a circular cas ing whose upper side is formed into a hopper, a rotary turbine Within said easing formed with an abrading surface substantia11y'fiiistocoiiioai in forni, and exposed through said hopper, blades radiating from the turbine and spaced apart, stripper blades fixed to the hopper and spaced apart around the turbine, and disposed to cooperate With said abradng surface, and means for rotating said turbine.

In testimony whereof We have signed our 10 naines to this specification in the presence of two subscribing Witnesses.
