DANIEL S. CHAPIN, OF MILFORD, MASSACHUSETTS.

ROLLER-GIN.

SPECIFICATION forming part of Letters Patent No. 400,190, dated March 26, 1889.

Application filed August 16, 1888- Serial No. 282,842. (No model.)

To all what/1 it Hwy concern:

Be it known that I, DANIEL SIMEON GHA- PIN, of Milford, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Roller-Gins, of which the following is a specification, ref,- erence being had to the accompanying drawings, in which- Figure 1 is a broken front elevation, Fig. 2 a broken plan, and Fig. 3 a broken rear elevation, of a gin embodying my invention. Fig. 4 is a section on line 4 4 of Fig. 2, and Fig. 5 is a section on line 5 5 of Fig. 1.

The object of my invention is to produce a gin in which the seeds are effectually separated from the cotton without injury to the staple or fiber; and my invention consists, mainly, in the combination of the main cylinder, seedarrester, and beater shown in Patent No. 284,223, dated September 4, 1883, with a fan arranged to prevent the cotton from passing over the beater, as more fully explained hereinafter.

Another feature of my invention relates to quickening the feed, and consists in the combination, with the cylinder, seed-arrester, and beater, of a hood, through which a draft of air is maintained.

In the drawings, A is the main frame; B, the main cylinder; D, the beater, and G the seed-arrester, these parts being substantially as shown in Patent No. 284223.

F is the fan. Cylinder B, beater D, and fan F are mounted on the main frame, and are respectively rotated, as indicated by arrows in Fig. 4. Cotton to be ginned is fed to the main cylinder from chute H, of ordinary construction, and portions of it are carried by the rotation of cylinder B under s eed-arrester G, held up to its work by springs g, substantially as in the Osgood patent, No. 284,223. The beater D strips the seeds from the cotton, and the fan F prevents the unginned cotton from passing over the beater D. This combination of the fan with the beater, the main cylinder, and seed-arrest-er is the main novelty of my invention, and is a highly-important improvement on machines of this class.

Hitherto in Osgoods gin, described in Patent No. 284,223, on which gin mine is an improvement, some of the unginned cotton has Another feature of my invention is the combination of the beater, seed-arrester, and main cylinder with a hood, J, and draft-pipe j, in

which a current of air is maintained in the direction shown by the arrow in the pipe j in Fig. 4 by means of any suitable contrivance say, for example, by means of a fan in the pipe, the fan being constructed and arranged in the pipe in a way too well known to require description-and this draft aids in drawing the cotton toward the seed-arrester and main cylinder, and thereby greatly increases the capacity of the gin.

The hood is mounted on the frame of the machine and covers the rotary parts above referred to in a well-known way; and as the pipe in which the draftreferred to opens. out of the chamber formed by the hood and other parts of the machine the operation of the draft-creating apparatus in the, pipe sucks in air through chute H, in which the cotton to be ginned is placed,and so aids in drawing the light fibers toward the seed-arrester and cylinder, as above stated. The cylinder B is best provided with longitudinal grooves b, forming a roughened surface, on which the fibers are caught as the cylinder rotates.

The hood J is conveniently formed of side pieces, 1, attached to thesides of the machine and projecting above the fan, and the curved piece 3, the lower edge of which is supported bya cross-piece, 4, (see Fig. 4,) the upper portion resting upon the side pieces, 1. The side pieces, 1, are provided with springs 2, projecting above them and adapted to pass through the holes in the part 3 to keep the part 3 in place on its supports 1 1 and 4. As shown in the drawings, the part 3 extends from the cross-piece 4 upward and forward over the hood and reaches from one side of the machine to the other side thereof.

In practice I drive the fan, beater, main cylinder, and doifer by a series of belts, a, and pulleys a, the stud '5, which is secured to the frame of the machine, carrying two pulleys, a, one of which is belted to a pulley, a, on the journal 6 of the cylinder B, while the other pulley, a, on the stud 5 is belted to a pulley, a, on the shaft '7 of beater D, this shaft 7 being provided with another pnlleyga, beater and the quantity of cotton ginned in 15 at its opposite end, which belted to a pula given time is greatly increased. ley on the journal Set the dolifer I, with which \Vhat I claim is my machineis providechthe dofler having the 1.
