lIMPROVED MACHINE FOR CUTTING TOBACCO.

Specification forming part of Letters Patent No. iilio, dated March 21, 1865.

and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a back elevation; Fig. 2, a longitudinal vertical section, and Fig. 3 a side elevation.

The same letters indicate like parts in all the igures.

My invention relates to ymachinery for..cut-. ting tobacco by revolving knives, as it is gradually advanced in a trough, by mechanism which can be readily adjusted to determine the extent of feed between any two cuts.

In the accompanying drawings, a represents a suitable frame, in the upper part of which is formed a horizontal bed, b, with parallel sides c c, to form a trough or way to receive the tobacco to be cut, and in which it is moved toward the cutters. To this trough is fitted a cap-plate, d, which, after the tobacco has been placed, is held down by a wedge-key, e. At the side of the trough is mounted a horizontal shaft, f, to the front end of which is secured a wheel, g, with arms and a crank-handle, and to the inner face of the hub and rim of this wheel are secured cutters h h, which stand off from the inner face of the arms sufficiently for the passage of the cut tobacco. I make the cuttingedge of the cutters convex in the form of a segment of a circle, to obtain a gradual drawcut, and I make them either smoothed or serrated, according to the purpose for which the tobacco may be intended. The front edge of the trough should be of steel, with a sharp square edge to facilita-te the cutting operation. The tobacco is fed or pushed forward by a follower, fi, on the end of ascrew, j, which passes through a rotating nut, k, mounted in the frame. The nut k carries a ratchet-wheel, o, which is actuated by a pawl, p, on an arm, q, which turns on the rear part of the nut k, and this arm q receives a vibratory motion by a connecting-rod, r, from a crank, s, on the rear end of the shaftf.

To regulate the extent of feed, there is a camplate, t, against the inner face of the ratchetwheel, and mounted so that it can turn on the nut k. A portion of the periphery of this plate is of less diameter than the ratchetwheel, and the rest of greater diameter, so that as the arm q vibrates the pawl q the cam form of the edge of the cam-plate will determine when the pawl shall act on the ratchetteeth. The cam-plate is held by a screw passing through a segment-slot, a, to admit of setting it, so that by turning and setting the plate the extent lof feeding-motion can be readily adjusted.

What I claim as my invention, and desire to secure by Letters Patent, is

rIlhe combination, substantially as herein described, of the non-rotating feeding-screw, the rotating nut mounted thereon and provided with a ratchet-wheel, the vibrating pawl or ratchet-hand, and the adjustable cam-plate for determining the extent of feed-motion which shall be imparted to the ratchet-wheel, for the purpose specified.
