UNITED STATES PATENT OFFICEo DAVID R. KINYON, OF RARITAN, NEW JERSEY, ASSIGNOR OF ONE-HALF HIS RIGHT TO JOB O. KINYON, OF SAME PLAGE.

IMPROVEMENT IN MEAT-CHOPPERS.

Specification forming part of Letters Patent No. 183,938, dated October 31, 1876 application filed August 19, 1876.

To all whom it may concern Be it known that I, DAVID R. KINYON, of Raritan, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Meat-Chopping Machines; and that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this speciiication, in which- Figure l represents a perspective view of the machine. Fig. 2 represents a top View ot' the frame with the upper parts removed. Fig. 3 represents a vertical section of the same through the axis of the chopping-block.

Similar letters of reference Where they occur denote like parts of the machine in all the iigures.

My invention relates to machines for chopping meat, vegetables, &c., in which a slow rotary motion is transmitted to the block upon which the chopping is done, while a series of knives are raised and lowered above it, operating rapidly upon the meat to reduce it to ne and uniform particles; and the object of my invention is to locate the center of the block in relation to the center of the frame and knife-arm, upon one side of it, so that 011e of the knives shall cut to the center of said block, thereby preventing clogging. lts object is also to construct the frame out of as few pieces as possible, to make it stronger and the fitting of the parts less expensive; and making the knife-arm adjustable and removable, it can readily be taken oft the machine to clean or renew the chopping-block, and be replaced in position without removing any other part of the machine.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the draw- 1n gs.

'lhe frame is cast in two pieces, the part A having formed upon it the vertical guideway a for the heel or guide c of the knife-arm C; the boxes al, to receive the main shaft d; the ears a2 and a3, to carry studs for axis of revolving parts, as will be described hereafter 5 the socket for one of the side bearings and for the central spindle e of the choppingfblock E, and

one of the feet of the machine, all these parts being formed in one casting. The part B of the frame has two feet, b, and the two sockets for the side bearings b1 for the block E, and is connected to the part A of the frame by two bolts, b2. The knife-arm C and its guide c are cast in one piece, the guide c fitting the guide- Way a. on the main frame. The knife-arm is mounted upon a vertical power-rod, F, and the side strain upon it is relieved by the heel or guide c, bearing against the guideway a, formed upon the frame. This arm is made adjustable to the power-rod F by means of a setscrew, g, so that it can be lowered bodily with the knives G, as the block E becomes worn, or can be taken off the power-rod and the block removed after the meat is cut. The knives Gr receive a reciprocating motion by means of the crank-pin h, projecting from the disk H, working into the slot-piece f, cast to the upright power-rod F, the rod being guided by two arms, c', bolted to the frame A. The block E is revolved slowly by means oi' an eccentric, k, cast upon the hub of the fly-wheel K, operating upon the forked lever l, pivoted to the ear a3 of the frame, this forked lever operating upon a lever, m, pivoted to the spindle e, and located horizontally beneath the block E. The lever m carries a spring-pawl, n, that engages with the ratchet-wheel E]l ot the block E, and receiving cylinder E2. The center of the revolving block is not in a line with the center of the knife-arm, but so placed that one knife shall cut to the center of the block, and the other as far from it as the knives are apart, so that the meat lying at the center ot' block always passes under one knife, and the space at the side of the lirst-acting knife, between it and the rim of the block, is less wedging, thereby preventing clogging.

To operate with this machine, the meat or other substance is placed within the cylinder E2, and motion given to the gear-wheel M by means of the handle M', or otherwise. This gear-Wheel, rotating upon a stud riveted to the ear a2 of the frame, transmits its motion to the pinion N, mounted upon the main shaft d, and through it to the dii'erent parts of the machine.

In small machines, for family use, I prefer to employ a single knife, operating upon the block at right angle with the knifearm G.

Having now described my invention, I claim- 1. The block E, located upon one side of a vertical longitudinal plane passing through the center of' the knife-arm, in combination with said knife-arm, carrying two knives, acting together substantially as and for the purpose described.

2. The knife-arm C and its extensionguide c, the gnideway a, boxes al, ears a2 and a3, and socket for spindle e, constructed and arranged as and for the purpose described.

3. In combination with the power-rod F and
