MEAT-MINCING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 262,893, dated August 15, 1882.

Application tiled April 2i, 1882. (No model.) Patented in Germany March 4, 1881, No. 17,180, and in England October 25, 1881,

To all whom it may concern Be it known tllat I, CARL ANDREAS HAM- MER, Sr., a subject of the Duke of Brunswick, and a resident ofBrunswick, Germany, have invented certain Improvements in Apparatus for Mincing Meat and other Substances,(i'or which I have obtained German Letters Patent N o. 17,180, March 4, 1881, and British Letters Patent No. 4,666, October 25, 1881,) of which the following is a specification.

These improvements relate to a peculiar arrangement destined for imparting a concentric and at thc same time an eccentric revolving motion to the chopping-block of the apparatus.

The annexed drawings represent an apparatus embodying these improvements.

Figure l is a partial vertical section and side elevation, and Fig. 2 a top View, ot the apparatus, the chopping-block being taken off in order to allow an easier explanation of the arrangement.

The whole apparatus is mounted on a frame, B, placed upon the foundation A. It is intended to be driven by machinery, the moving-power being transmitted to the mean shaft O by'means of a belt. On this shaft there are placed two pulleys. The one, D, is destined to convey motion to the shaft C', which imparts a rocking motion to the chopping-knife G by means of the crank a and connecting rod b, and the other pulley, E, transmits motion to the lower shaft, c. The vertical spindle d receives its motion from the latter by means of the Vworm e and worm-wheel j, and carries at its upper end two pinions ot' different diameters, g and g. The larger one of them gears with the upper wheel, H, and the smaller one with the lower wheel, I, which is a little larger than the upper wheel, H, which turns loosely upon the nave of the latter. From this it results` that at every revolution of the spindle d the wheel H turns a little faster than the Wheel I. The choppingblock K is provided at its bottom with a circular metallic plate, h, embracing the lower edge of the block, which plate rests directly upon the wheel H. The nave i of the wheel weight of the latter and the block K, together with the chopping-knife G, rests upon the four supports l, provided with rollers on which the whole arrangement rolls.

Il", now, the apparatus be'put into action, the wheels H and I will turn lorwardly at'the rate of the different number of teeth ofthe wheels, Fig. 1, in gear. The upper wheel, H, revolving round the nave i, takes along with it by friction the chopping-block K, which turns round the pin 7c. As the wheel I is put into rotation, at the same time the pin 7c or the center of revolution ofthe bloei: performs a circular motion, causing thus the block to slide partially upon the wheel H, in the same time turning round the pin lr. Thus it results that during one complete revolution ot' the wheel I the block will at successive moments assume always another eccentric position in relation to the center, L, of revolution of the wheels H and I.

Figs. 3 and 4 show a modification of the above-described arrangement. In this case the upper wheel, H, on which the block K rests, is provided with internal teeth, and is larger than the lower wheel, I, the latter being externally toothed. Both these wheels are moved by one pinion, g, placed betweenV the internal and external teeth of the wheels, the spindle d receiving its motion in. the same way as above described. It will be understood that in this case the wheels H and I do not revolve in the same direction as in the arrangement shown by Figs. 1 and 2 5 but the one moves in opposite direction to the other.

I claim as my invention- 1. A meat-mincin g apparatus having a chopping-block and devices, substantially as de scribed, for imparting a planetary motion to said chopping-block. I

2. The combination ot' the chopping-block of a mincing-machine with wheels H and I, one carrying an eccentric pivot for and the sys Y other in frictional contact with said block, and turning said wheels at different speeds, all snh- 1o 'devices for rotating said Wheels at different stantially as described.

speeds, substantially as set forth. In testimony whereof I have signed my name 3. The combination of the cutting-block of to this specification in the presence of two suba meat-mincing machine with a wheel, I, havsorihing witnesses.
