MARTIN SHIRK, OF EPHRATA, PENNSYLVANIA.

TOBACCO-GRANULATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 308,101, dated November 18, 1884.

Application filed October 22, 1883. (No model.)

T0 ZZZ whom it' may concern.-

Be it known that I, MARTIN SHIRK, a citizen of the United States, residing at Fphrata, iu the county of Lancaster, State of Pennsylvania, have invented certain Improvements in Tobacco-Granulating Machines, of which the following is a speciiication.

My invention relates to improvements in tobacco granulating or scrapping machines and the objects of my improvements are, first, to cut the tobacco into scraps, and, second, to separate the different sizes of tobacco cut, the one from the other.

I illustrate my device by means of the accompanying drawings, which form part of this specification, in which similar letters refer to like parts throughout the several views.

Figure I is a view of the side of the machine on which the power is applied; Fig. 2, a view of the reverse side. Fig. 3 is a top view with the hopper removed. Fig. 4 is a top View of the hopper. Fig. 5 is a vertical section through line x x, Fig. 3. Fig. -6 is a perspective view of the concave breaker-bed and the horizontal cylinder, and Fig. 7 is a perspective view of the relative positions ofthe screens E and F.

In these two last views there has only been enough of the receiving-box shown to explain the movements of the internal parts.

In my device the tobacco is fed into a hopper, A, resting upon the top of the receivingbox B of the machine. The hopper feeds into a concave breaker-bed, C, the whole bottom of which is formed of a coarse sieve, S, with a mesh that will allow particles of the required size to pass through, from the upper part of the inner side of which project wrought-iron or steel teeth t, set in two horizontal rows, the one above the other, and so arranged that the teeth of one row are set opposite the center of the openings between the teeth of the other row. A horizontal cylinder, D, on the shaft s fits in the said breaker-bed, and is revolved by the cog-gearing g g', having the crank a attached, the shaft being supplied'at the end opposite the gearing with a ily-wheel, w. This cylinder D has two sets of teeth, r, about its circumference, which, as thecylinder revolves, pass between those of the bed. These teeth are square, having theirfacets perpendicular and horizontal, so that when they engage the respective facets of the one set shall be parallel with those of the other set. rIhe bottom of the hopper Ahas an opening, A', in it, covered with a sieve of .the same mesh as that forming the bottom of the breaker-bed. The cog-Wheel gis mounted on a pin, z, secured in the side of the receiving-box B. It is so mounted in order to avoid passing an additional shaft through the receiving-box. Below the breaker-bed there is a screen, E, having a finer mesh than that of the breaker, which moves alternately back and forth longitudinally in the machine, the delivering end c of which projects back of the receiving-box. Under E there is a still iiner sieve, F, suspended at right angles to it, and. having a movement perpendicular to it. Screen E is suspended by two arms, b, inside the receivingbox behind and one, d, outside in front, and

screen F by arms f at one side and hat the other.'

Motion is communicated to the screen E by means of a cam, c, attached to the-shaft s between the receiving-box and the fly-Wheel, and the lever I, having its fulcrum at Z, one end of which is curved, so as to embrace the cam, and the other bent at right angles, so as to enter the receiving-box through the circular slot ,where it is connected with the sieve. The sieve F is moved by a lever, m, having two horizontal arms at right angles with each other-one, a, attached to the sieve E through a slot in the receiving-box, and the other, a, secured to the sieve F. The vertical part p of the lever, passing through a covered slot in the cross-piece q of the frame supporting the receiving-box, serves as a fulcrum for the arms. As will be seen, by this arrangement the oscillating movement of the arm attached to the sieve E in one direction causes a movement of a similar kind of the other arm in the other direction. The sieves are sloped so as to cause them to gradually discharge their contents E to the back of the machine, and F into a receiving-box, It, having a sliding bottom, o, and a movable top, o. A box, H, is placed beneath the sieve F to receive such tobacco-dust as passes through it. riDhe hopper can be removed from the top of the receivingbox when necessary.

In using my device the tobacco'is put into the hopper, when such particles as are small .IOO

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

1. A concave breaker-bed, C, having a sievebottom, and teeth projecting from the upper edge of said bottom, in combination with the cog-gearing gg', shaftlS, with cylinder D, having teeth, the cam c, lever I, and sieve E, as herein described.

2. The fixed concave breaker-bed having a sieve-bottom, combined with the suspended sieves E and F, arranged to deliver at right angles to each other, and oscillated by levers I and m, respectively, with the actuating mechanism and the horizontal cylinder D, as herein more fully described.
