other direction, and all at a rate sufficientlyrapid to render the operation a profitable one, and to that end the improvement relates mainly to the means immediately used in separating the lint from the seed. It also has refeience to the-general arrangementof the mechanism, and to certain details of construction', all substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this speciiication, in which Figure 1 is a plan of the improved'mechanism in its most desirable form; Fig. 2 a side elevation of the same, the casing which contains the brush and the coacting abradingdisk, as well as a portion ofthe' seed-supply passage, being in section; Fig. 3 a vertical section on 'the line 3-3 of Fig. 1; Fig. 4 a vertical section on the line 4 4 of Fig. 5, which, in turn, is a horizontal section on the line 5-5 of Fig. 3; Fig. 6 a detail, upon an enlarged scale, being a section, of aportion of thebrush and also the disk, upon the line 6-6 of Fig. 7, which is a view, also upon an enlarged scale, of a portion of the disk, the View being from the rear, or ouget, side thereof.

The same letters of reference denote the same parts throughout the several views'.

A represents a suitable frame for the working parts of the machine.

B represents a brush suitable for rasping cotton-seed, or for forcing cotton-seed against a rasp or abradingsurface. Its bristles b, are preferably steel wires attached to a suitable back b', which, in turn, is held in a head b2, substantially as shown. C represents an abrading, perforated, part which coacts with the brush, and, with the brush, constituting the mechanism immediately employed in re moving the lint from the seed. The brush is a revolving one, and the part C is also adapted to rotate, although the parts, B, C, might be adapted to move reciprocatingly with reference to each other and the improvement thereby in a measure carried out. In its present form the part O is in effect a revolving disk having projections, c, extending in the direction of the brush, and openings, c', the projections, in conjunction with the brush-teeth,

`serving as Scrapers, knives or points to remove the lint from the seed, and the openings, c', providing outlets through which the lint, after being'separated from the seed, is withdrawn. That is, the seed to be delinted is introduced between the brush and the disk, and the lint is separated from the seed by being in the first place cut from the seed by means of the coaeting brush-teeth and diskprojections, and in the second place by being removed from between the brush and the disk immediately after being detached from the seed. As now shown both the parts or disks B and O, being placed on a horizontal shaft will be vertically arranged.

A leading feature of the improvement is withdrawing the lint from out'ot' the field in which the brush-teeth rand .the opposing abrading-disk coact as soon as possible after it (the lint) has been separated from the seed,

and not allowing the separated lint to be carried around and around between the brush and surface,or to remain in, and more or less close, the outlets in thevdisk.

The improvement is more effectively carried out by causing the two parts, the brush andthe disk, to revolve inopposite directions, as thereby the seed is more effectively worked between the brush and disk, and the openings in the disk, which constitute the outlet-s through which the lint is discharged, are better kept open. To these ends the brush is attached to one shaft D, and the disk is attached to another shaft E, and these shafts are independently journaled in the machine and adapted tobe rotated `at different rates, and, in opposite directions. For this purpose the-shaft D is journaled in the bearings (Ld, and is provided with the pulley d', and the shaft E' is journaled in the bearings e, e, and is provided with the pulley e', and by means of belts (not shown) leading to the pulleys d', e', respectively, and in different directions respectively; Ithe pulleys are driven in different directions, as indicated respectively by IOO the arrows, d2, e2, and the brush and disk accordingly rotated` and as indicated by the arrows b3, c2. The disk-projections also point suitably, as shown substantially, to coact with the brush. The rates at which the brush and disk respectively rotate is va matter of irnportance, as I have discovered that the parts in question, to obtain the best result, should not bc rotated at the same speed, but the brush should be rotated faster than is the disk. By means of the screw, e3, working through a bearing, e4, and against theend of the shaft E, that shaft can beadjusted to hold the disk nearer to, or farther from, the opposing brush, as may, in practice, be desired.

The seed to be treated is delivered between the brush and disk preferably by introducing the seed through an annular opening, c3, at the center of the brush, and a desirable arrangement therefor is as follows:

F represents a trough arranged at a suitable height, and containing a feed-screw, f, whose shaft, f', is journaled in the ends of the trough, and which is furnished with a pulley f2. The feed-screw is conveniently rotated by means of a belt, not shown, which leads from a pulley, d3, upon the shaft D to the pulley fz, and the seed, having been delivered into the trough, is fed thence through a suitable passage, ]"3, and through an opening, g, in the casing, G, which contains the brush and disk, and, after entering the casing, the seed passes through the opening c3, in the brush and thence finds its way to between the brush and disk. The joint between the side of thevcasing and the brush is suitably closed by means of the flanges, g', and b4, upon the y casing and brush respectively, and which lap pon each other substantially as is shown in rlhe casing, G, is constructed toinclose the brush and disk, and also a chamber, I-I, at the rear, or outlet-side, of the disk. The most desirable form for the disk-projection, c, is the one shown, namely, a knife-like edge eX- tended in a radial direction upon the disk and being the edge of a lip which overhangs the opening c, and which serves to support a cutting or rasping edge in position to coact with 'the brush-teeth, and as a deflector to die rect the lint to the opening c", substantially as shown. The described openings and projections extend throughout thedisk, c4, which constitutes the body or principal part of the abradingdevice, and they are readily formed by striking up portions of the disk which. is usually of sheet-steel, the edge of the struckup portion forming the rasp or knife, and the hole made by striking up the metal being the lint outlet. There is anoutlet, g2, in the casing opposite lthe space between the brush and disk for the discharge of the denuded seed, and another opening, g3, may be formed in the lower part of the casing through which dirt collecting in the chamber Il can be dis` charged. The joint between the rim, c5, of the disk and the shell of the casing is suitably closed by means of the flange or packing ring g4. Any other suitable means may be employed to prevent the air from being drawn, to an undesirable extent, between the periphery of the disk and the shell of the casing.

I represents a due leading from the chamber II to a chamber J. This last named chamber contains a fan, K, attached to a shaft, lo,

and rotated preferably by means of a belt, not

shown, leading to a pulley 7c', attached to the shaft k. The flue I is for delivering the lint from the chamber I-I, and the fan K is a suitable air-movin g device for drawing the air and lint through the disk into the chamber II and thence into the chamber J whence, through a suitable outlet, j, therefrom, the lint is discharged, all as indicated by the arrows fr. The flue, I, is turned, and. the shaft k and fan arranged,as shown to bring the shaft 7c parallel with the shafts D, E, and thus facilitate the application of the driving-power to all parts of the machine.

The disk G,is,in practice, madein sections, 015, which are secured to a frame c, as shown. The back of the brush may also be in sections which are bound upon the head by means of the hoop b5.

A certain amount of dirt and foreign matter is liable in practice to pass with the lint into the chamberl-I. This chamber not only serves as a passage for the lint but also as a dust-settling chamber, and quite a portion if not all of the dirt carried into it, by reason of its gravity,-falls to the bottom of the chamber,

and it may be withdrawn therefrom through any suitable outlet such as shown at g3. This outlet, by any suitable means as by slide g5 is adapted to be closed, saving when it is desired to withdraw the dirt from the chamber. To more thoroughly separate the dirt from the lint a beating-device may be employed, such for instance as shown at L, Fig. 5, but not shown elsewhere. This device may be any revolving wheel having means such as the paddles, Z, for striking the lint and shaking the dirt therefrom. In the present instance the beater is shown secured to the hub of the disk C. But it maybe otherwise constructed and operated to accomplish the desired purpose. If desired another beater, M, may be, and for an analogous purpose, arranged at some point in the lint-discharge flue in the vicinity of the fan K. In the present instance this last named beater is shown secured to the fan-shaft 7a.

In operation the seed to bedelinted is fed at a suitable rate through the brush to be received between the brush and the disk. The lintis removed by the brush-teeth and the disk-projections jointly acting upon the seed, and the denuded seed is discharged through the outlet g2 and the lint is drawn through the openings, c', into the chamber H. The fan K exerts sufficient force to draw the lint from between the brush and disk and,m'a the chamberH and flue I into the fan-chamber and, ultimately, to dis- ICO vIIS A charge it through the outlet, j, to any desirable point. The action of the fan is facilitated, and the lint more effectively discharged in the direction mentioned, by reason of the described rotation of the disk. Such rotation operates not only to agitate the particles of the lint, and to facilitate their transit through the disk-openings, but also to bring all portions of the disk equally into position for the suction of the fan to act most favorably thereupon. The inlet, c', to the flue I is, as seen, at one side of the chamber I-I, and,by reason of the revolution of the disk all parts thereof are successively carried into the most direct line between the brush and theinlet c', and there is no tendency to clog in any part of the disk.

The brush must be rotated at a suiiiciently rapid rate to cut the lint from the seed, and the disk must also be rotated and in the opposite direction to that of the brush, but ata slower rate. In practice the brush is run from tive hundred to six hundred revolutions a minute, and the disk from one hundred and eighty to two hundred.

I claim- 1. In a cotton-seed delinter, the combina`- tion of arevolving brush, an opposing perforated disk, revolving slower than the brush and in an opposite direction, and an airex hausting device, said brush and disk being adapted for jointly effecting the separation of the lint from the seed, and said air-exhausting device withdrawing the detached lint through the disk, substantially as described.

2. The combination of the4 trough for receiving the lint-bearing seed, the casing, the passage leading from said trough to said casing, the revolving brush having the central-
