IMPROVEMENT IN Hemp-BRAKES.

' Specification forming part of Letters Patent No. 144,301, dated November 4, 1873; application filed April 26, 187e.

' construction and arrangement of a machine for breaking hemp, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a front elevation, and Fig. 2 a transverse vertical section, of my machine.

A represents the frame of my machine, constructed in any suitable manner to contain the various working parts thereof. Along the front in the upper part of the frame A is a feedtable, B, over the inner edge of which is an inclined band, C. Directly opposite the feedtable is a revolving hexagon or polygonal shaped cylinder, D, provided with longitudinal ribs a a, each rib being perpendicular with the cylinder on the front side and curved on the back. Below this cylinder in the frame are two revolving heXagon or polygonal shaped drums, E and G,both provided with ribs similar to those on the cylinder D. These drums are of dierent size, and the ribs on both of them are placed in the same manner as those on the cylinder-that is, having a straight or perpendicular side in front and the rear side curved. The cylinder and drums are so connected by pulleys and belts, or other equivalent means, that the smaller drum E and the cylinder D will revolvein the same direction, while the larger drum G m'll revolve in the opposite direction, as indicated by arrows in Fig. 2.

Any power may be used to run the machine, such power being applied to a pulley on the shaft of the large drum G.

The operation of the machine is as follows:

The operator takes a bundle of the stalks of -hemp around the smaller end, and spreads the other ends across the table B, and moves the hemp forward, when it comes in contact with the ribs a of the cylinder D, which snap the stalks oft' from one-half to three inches in length. When the bundle is fed in to about .one-half its length,it is drawn back,which can be easily done without stopping or reversing the motion of the machine. The hemp is then reversed and fed the other end through, and then, in like manner, drawn back again, when the operator throws it over a pole behind him, where a man is to stand to tie it up in bundles. It is held securely in the hands all the time the machine is at work on it; consequently it cannot get entangled, but comes from the machine cleaned and straight. As soon as the ends of the stalks are snapped oif, the lint descends between the table and cylinder, and comes in contact with the drums, which, in revolving toward leach other, take it down between them, and whip or fiail it both on the bottom and top, and rid it of any particle of woody matter; then, as it is drawn from the machine by the operator who feeds it in, as above stated, the lint is dressed nicely and left straight and pretty, the cylinder and drums revolving in the opposite direction to that in which the hemp is drawn out.

This machine is cheap, durable, and very simple, and combines the rare qualities of both breaking and cleaning hemp well. It does not `crush or grind up hemp, but it comes from the machine well cleaned, straight, and glossy. Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the cylinder D with the i two drums E and G, all of different sizes, and

eachprovided with the ribs a a, said cylinder and drums revolving at different rates of speed, as and for the purposes herein set forth.

In testimony that I claim the foregoing' I have hereunto set my hand this 1st day of April, 1873.
