MEAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 407,056, dated July 16, 1889.

Application filed October 1, 1888. Serial No. 286,861. (No model.)

To all whom it may concern:

Be it known that we, PETER H. BRODESSER and PETER J. TERNES, of Milwaukee, in the county of Milwaukee and State of lVisconsin,

have invented new and useful Improvements in Meat-Cutters; and we do hereby declare the following to be a full, clear, and exact description of said invention, reference being had to the accompanying drawings, and

[O to the letters or figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in that class of meat-cutters in which a number [5 of curved-edge knives fixed in a frame in a set are given a rocking motion, whereby they are adapted for mincing meat 011 a rotating block.

Figure 1 is an elevation of a complete device embodying our improvements. Fig. 2 is a plan of the wheels and attached mechanism, whereby a rotary and an eccentric movement are given to the meat-block. Fig. 3 is a detail of a ratchet-wheel and pawl used in raising the knives away from the block. Fig. 4 is a view from above, or plan of the complete machine. Fig. 5 is a central vertical section of the meat-block and its supporting mechanism. Fig. 0 is a detail of the mechanism for rotating the meat-block. Fig. 7 is a detail showing the method of attachment of the rods for driving the meat-block-rotating mechanism with the driving-shaft. Fig. 8 is a detail of the device by which each knife is secured adjustably to the supporting-frame.

The same letters refer to like parts in all the views.

A number of knives A A, having a convex cutting-edge, are arranged at a distance apart, but parallel to each other, and are secured adjustably at each end, respectively, to the knife-frame a by means of a bolt Z), having a bifurcated lower end,which is riveted or bolted to the end of the knife-blade, which bolt 1) is 45 provided with a screw-threaded shank having thereon two nuts 0 0, one of which is turned against th e under and the other against the upper side of the frame a, through which the shank of the bolt passes, whereby the knife is secured firmly, but adj ustably, to the frame. These knives rest on their edges on the block G, and the frame a is connected thereto by the pivoted rods F F, and to the fiy-wheels E E at a radial distance from the axis of the driving-shaft D, on which the wheels E E are fixed, whereby by the rotary motion of the shaft D and the fly-wheels E E thereon the knives are given arocking movement endwise on the block G. The shaft D is rotated by a belt 13 running on a pulley C, fixed 011 the shaft D, which belt is carried by the power-supplying mechanism. (Not shown.) A pair of bent arms (Z (1, one at each side of the knife-carrying frame, are pivoted at one end, respectively, to the front end of the frame a and at their other ends to the shaft-supporting frame 6. These bent arms (Z (Z are intended and adapted for guides for controlling and limiting the movement of the knives A, and are not a necessary part of the mechanism, but are preferably used therewith. An arm f, secured rigidly to the frame a, projects rearwardly therefrom, and is provided with a bifurcated end adapted to impinge against and rest on the bracketrarm g when the frame a is tilted rearwardly sufficient therefor.

The bracket-arm g is rigid on the shaft 71, which is journaled and supported on the frame 6, and is provided with a lever-handle i, which is also rigid to the shaft h. Acheckpawl jis pivoted on the frame 6, and is adapted to engage with the ratchet-wheel 7t, rigid on v the shaft h. W hen the knives are tilted rearwardly until the arm f rests on the bracketarm y, then by hearing down on the leverhandle 71 the knives are raised away from the block G, and by the engagement of the pawl j with the pinion 7t: the knives are supported away from the block G. This is convenient 0 and desirable when it is necessary to clean the surface of the block G or for cleaningthe knives. Abrake-shoe Z is pivoted to the frame 6, and is adapted to be held against the flywheel E by means of an eccentric m, pivoted 5 on the frame eand provided with a handle a.

The meat-blockG rests on the false bottom 0, which is suspended adjustably vertically in the case B by means of the bolts 17 p, having screw -threads and nuts thereon. The I00 case R rests movably 011 the horizontal wheel S, which rotates about the central vertical arbor Q, which arbor is fixed rigidly in the supporting-base Y. The wheel S is supported and rotates 011 a series of bearing-wheels q q, journaled in standards fixed in the base Y. A horizontal cog-wheel P, rigid on the hub of the Wheel S, meshes with a worm O 011 the shaft N, which is journaled in brackets therefor supported on the base Y. The shaft N is provided with a ratch et-wheel r, fast thereon. Two connecting-rods K L are pivoted at one end to the outer ends of the severally independent arms M M, respectively, and the inner ends of the arms M M are pivoted on the shaft N, and the arms M M are each provided with a gravity-acting pawl 5, adapted to engage intermittently the teeth on the ratchet-wheel r, forcing it to rotate in one direction by the alternately-reciprocating movement of the rods K and L, the pawls being adapted to pass the teeth of the ratchet-wheel in the other direction. The rods K and L at their other extremities are by a common bolt pivoted on the face of the wheel U, the pivotal bolt 75 being provided with a head which enters and is adapted to travel in a T-shaped slot in and across the face of the Wheel U, which bolt is also provided with a nut 11, adapted to turn the meat-block G. The sprocket-wheel J is fast on the shaft T, which is journaled in brackets supported on the base Y. A sprocketchain I, running on the sprocket-wheel J, runs also on a sprocket-wheel II on the shaft D,whereby when the shaft D is rotated moticn is communicated to the meat-block G through the mechanism described.

bor Q, enters a recess or bearing therefor in 7 small arbor u the case R is adapted to rotate in an eccentric orbit. A cog-Wheel 4), projecting upwardly from the wheel S and having the same axis as the wheel S, meshes with a larger wheel in, having inwardly-projecting cogs extending downwardly from the case R, whereby, as the wheel S is rotated, the case B is caused to rotate in an eccentric manner on the wheel S. This eccentric movement of the case B is intended and adapted to present a constantly-changing surface of the meat-block Gto the knives A A.

\Vhat we claim as new, and desire to secure by Letters Patent, is

A small vertical arbor u, projecting eccentrically from the ar- 1. In a meat-cutter, the combination, with the knife-carrying frame a and an arm f, rigidly attached thereto, of a shaft h, journaled on the supporting-frame, and abracketarm g, provided with ahandle t', rigid on said shaft, substantially as described.

2. In a meatcutter, a horizontally-rotating wheel S, an arbor Q, rigid'to the frame, about which arbor the wheel S rotates, and an arbor a, rigid on the arbor Q, eccentric to the axis thereof and entering a recess therefor in the bottom of case B eccentric to its center,in combination with case B, resting movably on the wheel S and rotating eccentrically about the arbor u, a small cog-Wheel r, rigid on the wheel S entirely at one side of the axis of that wheel, and an inwardly-facing cog-wheel W, rigid on case R, eccentric to its arbor, and meshing with the Wheel 12, whereby the case R is rotated eccentrically about its own arbor and is carried eccentrically about the axis of the wheel S, substantially as described.

3. In a meat-cutter, a shaft N, having thereon a wheel meshing with a wheel on the meat-block-supporting mechanism, and a ratchet-wheel r, rigid on shaft N, in combination with oppositely-extending arms M M, pivoted at their inner ends on the shaft N, gravity-pawls s s, pivoted severally on the arms M M, and connecting-rods K and L, severally pivoted at one end to the outer ends of the arms M M, and at the other ends pivoted eccentrically by a common wrist-pin to a power-supplying wheel, substantially as and for the purpose set forth.

4. In a meat-cutter, a mechanism-driving shaft N, provided with a worm therefor, a ratchet-wheel r rigid thereon, and two oppositely-extending arms M M, pivoted at their inner ends on the shaft N, and provided with gravity-pawls s s, adapted to engage alternately with the ratchet-wheel r, in combination with connecting-rods K and L, pivoted the other end pivoted by a common bolt t eccentrically to a driving-wheel, and the driving-Wheel U, having a slot across its face, in which the bolt 25 is adjustably secured, substantially as described.

In testimony whereof we affix our siguat ures in presence of two witnesses.
