MACHlN FOR PICKlNG HUSKS, 84.0.

SPECIFICATION .Ten-ning part of Letters Patent No. 377.095, dated January 31, 1888.

Application filed July 25, 18s?. Serial No. 24:153.

intended for the Amanufacture ot' mattresses' and articles of a like kind; and the invention consists, first, in the provisions made for adapting the machine for all kinds of materials, such as husks, hair, wool, &c., and, second, in the provisions made for preventing the liability of injury to the attendant.

In the drawings which accompanies the specification, Figure l is a vertical central longitudinal section showing a picker arranged for pickinghusks orother materials ot' the same coarse nature. Fig. 2 shows thesame machine as arranged for picking hair or materials of the same nature, the view being` similar to that of Fig.1. Fig. 3 is a plan view of the lower portion of the machine. Fig. Lt is a crossseetion on line x .e in Fig. 2, `arts being in elevation. Fig. 5 is a similar view on line y y in Fig. 2. removable hood detached.

A is a frame which supports the operating parts of the machine, and which is ofsuitable strength and construction for support.

I) is a picker-drum, preferably in the form of a wooden drum, secured upon the shaft B', which isjournaled in suitable bearings upon the frame A. This pickerdrum is provided with the usual picker-teeth, C, which preferably consist of steel pins secured upon the cylindrical periphery of the picker-drum.

D is a concave secured below and in front ofthe picker-dru in and concentrically thereto. It embraces about one-quarter of the circumference of the pickerdrum, and is provided with picker'teeth likethe drum, which project within the interstices formed by the teeth on the picker-drum.

E, Fig. 2, is a concave arranged on the upper front side of the picker-drum. rIhis concave is provided with a reduced number of picker-teeth,preferably only with two rows, one

at the beginning and one at the end of the con cave; and this concave, instead of being fixedly secured to the frame like the other concave, is made removable. To this end the concave E forms a portion of a removable hood, which consists of two side pieces, F, of halfcircular shape, or nearly so, provided with the rearward extensions G and table L, and which loosely rests upon the top of the frame A and embraces the upper part of the bearings of shaft B, thereby holding the concave in tlXed relation with the picker-drum.

II II are two feed-rollers journaled between the sides GGbelow the upper concave, E, and the upper one of these feed-rollers is journaled in bearings, which are preferably carried by levers I, pivotally secured at J to the sides of the hood, and, extending forwardly, have secured to them the springs K, opposing their tension to the tendency of the upper feed-roll to rise.

Motion is communicated to the picker-drum by means ofthe pulley M, secured on the shaft B, from any suitable source of power, preferably from a large cranlrwheehdriven by handpower, placed at a suitable distance in rear, and from the shaft B it is transmitted to the feed-rolls by means ofsmall pulleys N,secured upon the shaft B, and pulleys O,secured upon the shafts of the feed-rolls H, there being a straight belt, O', on one side of the machine and a crossed belt, O2, on the opposite side, to cause the two feedrolls to run in opposite directions.

In practice, the machine being constructed as described, the material is placed on the table L and evenly and gradually fed in by the feedrolls. The picker-drum,running in the direction shown by the arrow in Fig. 2, carries the material through the upper concave, where it is subjected to the act-ion ot' the picker'teeth, and is then delivered in a picked condition at the rear end of the machine, where it is discharged by centrifugal force.

It will be noticed that in this construction of the machine the lower` concave is inactive, as the upper concave only docs the work in connect-ion with the picker-teeth.

A second arrangement ofthe machine is obtained by removing the hood which carries the upper concave, then placing a simple hopper,

P, in position, as shown, and reversing the ditransmitted by means of a crank or cranks for hand-power,and is then, by intermediate coggearing, conveyed to one feedroll and to the shaft of the picker-drum, and by intermeshing cog-wheels fromfone feed-roll to the other feed-roll. Such pickers place the operator who turns the crank so near to the discharge end of the machine that he is seriously incon- Venienced by the dust, and, also, the coggearing makes the machine extremely danger-V ous to life and limb, as thepicker-drum, to do its work properly,must be run at a very high rate of speed, and a short stoppage in case of danger or accident is impossible.

I have done away in my machine with the employment of cog gearing altogether, and

drive the rolls by belt-connection, which will easily slip.

Vhat I claim as my invention is l. The combination, with the revolving 3o picker-drum audits stationary concave, of a removable hood carrying a second concave, a pair of feed-rolls, and a feed-table, substantially as described. l

2. The combination, with the revolving 35 picker-drum and its stationary concave, ofthe removable hood provided with the feed-table L and carrying a second concave with a lesser number of picker-teeth than the stationary concave, and a pair of feed-rolls journaled in 4o said hood and operating in'connection with' said pickerdrum. v

3. In apicker, the combination of the frame A, revolving picker-drum B, shaft B', drive- ,pulley M, pulleys N, hood having concave E, 45
