MACHINE FOR DELINTING COTTON-SEED.

SPECIFICATION forming part of Letters Patent No. 402,232, dated April 30, 1889.

` Application filed Macha?, 1888. serial No. 268,728. (No model.)

To all whom it may concern:

Be it known that I, ROBERT HANIIAM COLL- YER, a citizen of the United States, residing Io others skilled in the art to which it appertains4 to make and use the same.

Myinvention relaties to machines for delinting or cleaning cotton-seed, the object being to remove thelint and iibrous coating; an-d to this end the invention consistsjin certain arrangements and combinations of parts, hereinafter described.

In the accompanying drawings, Figure l is a side viewof the interior of my improved 2o machine. Fig. 2 isa side elevation of the exterior of the machine. Fig. 3 is a broken end view of the same,'showing thebrusli-cylinders and screens. Y

` In the machine as illustrated in the draw- 2 5 ings I have shown three horizontal cylinders, l, 2, and 3, one above the other, each on its shaft K, journaled in a casing, I, which incloses said cylinders and which is suitably supported, as on legs I-I. The upper cylinder- 3o shaft is provided with a pulley, N, which is designed to receive a drive-belt, whereby motion may be imparted to the various cylinders.

Y Each of the cylinders is provided on its outer vsurface with a suitably constructed wire 3 5 brush, the bristles increasing in iineness from cylinder l to cylinder Within the casing I, and surrounding each cylinder, is a wire screen, A, concentric with each cylinder. The screen around the cylin- .1,o der l is connected at the bottom with the top of the screen around cylinder 2 by a wirescreen passage, C, andthe second screen is connected in a like manner with the .third screen by a similar passage, D,while thelowermost Screen has an outlet, E. The interior of the casing I, exterior to the several wire casings, forms a chamber, M, having an outlet surrounding the outlet E, and

an air-inlet at the top, as shown atG. The seed is introduced into the wire casing sur- 5o rounding the cylinder lby means of a conduit, B,'containing a feed-roller, F. On the outside of the casing l the shaft of the cylinder l carries a gear-wheel, 4, .which meshes with a pinion, 6, on the shaft of the cylinder 2, the said shaft also carrying a gear-wheel, 5. This latter gear Ineshes with a pinion, '7, on the shaft of the cylinder 3.

The arrangement of gearing is such that if the cylinder is run, say, fourhundred revolu- 6o tions per minute, the cylinder 2 will make five hundred revolutions and the cylinder l3 will make six hundred revolutions. Thus the speed of 'the cylinders is increased from No.1 to No. 3. It will also be seen that the slower cylinder has the coarser brush.

In operation the seed is introduced as stated, and the heavier and larger particles of lint and fiber are removed by cylinder land by centrifugal action forced through the wire 7o screen into the chamber M. The seed then falls to the second cylinder, having a finer brush and a greater speed, to throw the lint through the screen. The seed then pass to the last cylinder, having the nest brush and greatest speed, and all remaining lint is removed, leaving the seed in a thoroughlycleaned condition as it passes from the Inachine.

It will be seen that the passages C,.D, and So E are in a general tangential direction to the rotation of the cylinders, and thereby aid in causing the seed to pass from one cylinder to the other.A Y

I prefer in practice to extend the feed-Open- 8 5 ing B, the passages C D, and the outletE the entire length of the machine.

Having described the invention, what I claim is- In a machine for cleaning cotton-seed, the 9o combination, with the casing I of a series of cylinders arranged horizontally therein one above another land provided in succession with brushes of /increasing degrees of fineness, the wire screen A, concentric with each cylinder, the said screen surrounding the upper cylinder having' a conduit, B, and being In testimony whereof Iax my signature in 1o connected at its bottom by a tangential paspresence of two witnesses. sage with the top of the screen around the intermediate cylinder, and the said interme- ROBT. ll.
