FEED- CUTTER.

SPECIFICATION formingpart of Letters Patent N0, 258,013, dated May 16, 1882,

Application tiled March 11, 1882.

- and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, which form apart of this specification.

Figure 1 is a perspective view of my improved machine for cutting straw, tobacco, &c. Fig. 2 is a vertical sectional view taken longitudinally through the main shaft. Fig. 3 is a longitudinal sectional view of the machine; and Fig. 4 is a' section on the line a; .90, Fig. 3. Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to machines for cutting straw, tobacco, 850.; and it consists in certain improvements in the construction of the samewhich will be hereinafter fully described, and particularly pointed out in the claim.

In the drawings hereto annexed, A represents a suitably-constructed frame, the sides of which are provided with boxes. or bearings for the main shaft B. Mounted securely upon the main shaft is a disk or hub,O,having arms D D, which project in opposite directions. The arms D are provided at their ends with boxes E, in which the short transverse shafts F are journaled, the bearings for said shafts being formed by blocks Gr, adjustable in the boxes E by set-screws H. The shafts F carry at their front ends the circular knives or cutters I and at their rear ends pulleys or bandwheels J, connected by bands or belts K K.

a with an a'nnularly-grooved disk, L, secured to the side of the frame A, as shown. By this arrangement, when the main shaft is revolved the shaftsF, carryingthe circular cutter,will be M, so that it may slide vertically.

(Model) Q is a cross-bar arranged under box M, and having upward-projecting arms R, provided at their upper ends with hooks S hooking upon the shaft of the upper feed roll. Springs T, coiled upon the arms It, are interposed between the cross-bar Q and the bottom of box M, (or under side of the frame A,-) thus forcing the said cross-bar Q, arms It, and the upper feedroll in a downward direction.

' U is-a plate arranged in box M in rear of the feed-rolls, and having arms or studs'V projecting into vertical slots W in the sides of said box, in which the said plate may thus slide.

vertically. The front side of plate U is beveled at X, so that the material to be cut will readily pass from between the feed-rollers under said plate, which, by suitablyarranged springs Y, is forced in a downward direction, so as to hold "the material securely while being cut by the rotary knives, which havebeen above described, and which of course must be so adjusted as to sweep by the discharge end of the box.

Journaled in suitable hearings on the front side of frame A are a pair of short shafts,Z Z, having intermeshing pinions A. The shafts Z are connected by universal couplingjoints B and rods 0 with the shafts of the feed-rolls, which are in this manner operated, the upper feed-roll, owing to the universal couplin g-joint, operating equally well at any position which it may happen to. occupy in relation to the lower feed-roll. Oneof the shafts Z has a bevel-gear, D, meshing with a pinion, E, upon a short shaft, F, carrying at its'rear end a frictionwheel, G. The latter is operated intermittingly by means of curved or concave shoes H, secured upon the arms D of the main shaft B, and having rubbcrcushions or blocks I, which, by coming in contact with the friction-wheel G, turn itfor a distance regulated by the length of said blocks, thus operating the feed mechanism. i

By regulating the size of the blocks 1 the length of the feed may be r,egulated,and it will be observed that owing to the construction described the material to be cut is only fed when .the knives or cutters are at the greatest distance from the feed-box. At all other times it is stationary.

Having thus described my invention, I claim and desire to secure by Letters Patent "of the United States-- The combination ofthe feed-r01lers,thecoup- In testimony that I claim the foregoing as lings B O, the shafts Z, having intermeshing my own- I have hereto affixed my signature in pinions A and bevel-gear D, the shaft F, havpresence of two witnesses. ing pinion E and friction-wheel G, and the AUGUST BRANDT.
