COTTON-GIN.

Application filed September 28, 1910.

To all whom it may concern Be it known that 1, Ivan Murmurs, a subject of the Crown of Sweden, having announced my intention of becoming a citizen of the United States of America, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Cotton-Grins, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to cotton gins, and particularly to an improved means by which the cotton fibers are delivered after the seeds have been removed therefrom by the ginning members in a ginning operation.

My invention consists in certain novel details of construction and combinations of parts such as will be fully pointed out hereinafter, and in order that my invention may be thoroughly understood, I will 110w proceed to describe an embodiment thereof b aving reference to the accompanying drawings illustrating the same, and will then point out the novel features in claim.

In the drawings: Figure 1 is a view in transverse vertical section through a cotton gin constructed in accordance with my invention. Fig. 2 is a detail top View of a portion of a delivery roll employed.

The cotton gin illustrated is in general the form of gin known on the market to-day as the Empire Duplex Cotton Gin, and consists in the main of two ginning rollers 5 and 6 mounted to rotate in the same directic-n about axes disposed in parallel relation with respect to each other, a rotary stripping member 7 located between the two said ginning rollers with its axis parallel to the axes of the ginning rollers and in substantially the same plane therewith, and sta tionary bed knives 8 and 9 arranged for coaction with the rollers 5 and 6 respectively, being located respectively between the peripheral surface of the roller 5 and one side of the stripping member 7, and between the peripheral surface of the roller 6 and the other side of the stripping member 7.

Cotton to be ginned is fed to the rotating stripping member and to the ginning rolls from a suitable feeding device, the lower end of which appears at 10 in the drawings, the cotton thus fed being ginned at two points Specification of Letters Patent.

in the machine, one at the edge of the bed knife 8, and the other at the edge of the bed knife 9, the lint dropping from the surfaces of the rollers 5 and 6 while the seeds fall down through a grid 11 disposed beneath the rotating stripping member 7, whence they are conveyed away by a rotary conveyer 12. y

Beneath the rollers 5 and 6 are two inclined side screens 13 and 14 which converge downwardly toward a lint flue 15. There is an open throat 16 between the lint fine and the hoppenlike inclosure formed by the in clined side screens 13 and 14;, and located within the said throat is a discharge roller 17. This discharge roller is constructed in the form of a drum having a plurality of radial flexible blades 18 composed of leather, rubber, or similar material, and rows of pins or pegs 19 disposed in alternation with the said blades. The length of the blades is such that they will be slightly deflected by the walls 20 of the casing member in which the throat 16 is formed, the pins 19 upon the other hand being of such length as to readily clear the said walls.

ltn operation the discharge roll 17 is rotated in the direction of the arrow in Fig. 1, and currents of air are caused to pass through the lint flue 15. As the lint falls from the rollers 5 and 6 it will be guided by the side screens 1-3 and lt to the discharge roller 17 and in the rotation of the latter the lint will be delivered positively into the flue 15; thence the lint will be carried by the currents of air to the desired point of dis charge. In the rotation of the wheel 17 the blades 20 act to seal the throat 16 so that the proper air pressure may be readily main tained in the lint line 15. On the other hand the pins 19 act to engage the lint in such a way as to cause the lint to be positively fed into the lint flue.

What I claim is:

The combination with ginning members, a hopper below said members into which lint is dropped by gravity, a lint flue adapted to have air pressure therein, a discharge throat between the constricted end of the chute and said flue having surfaces in the same cylindrical plane with the axis thereof offset toward the side of discharge, a discharge roller rotatably mounted in the throat having pins projecting radially from its surfaces of the throat under pressure to preface, and elastic flexible blades projecting vent escape of air from the flue into the therefrom a greater distance than the radius hopper.

of said cylindrical plane, said pins and IVAR MEURLING. 5 blades being arranged to pick up the lint in the chute and discharge it into the flue, and

the blades arranged to bear against the sur- Witnesses: V I 7 D. HOWARD HAYWOOD, LYMAN S. ANDREWS, Jr.
