Lene/rs Patent No. $56,783, dem February 9, v1869.V

, IMPROVE!) MEAT-CHOPPER The Schedule referred to in these Letters Patent andmaking part of the sama.

To all whom 'it may concern Be it knownl that I, FRANZ G. SrnMnns, of Winona, inthe county of Winona, and State of Minnesota, have invented certain new and useful Improvements, in

Mounting the Meat-Blocks of Meat-Choppers; and j I do herebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this speci ication, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur'.

To enable others skilled in the art to construct and use said invention, I will proceed to describe it.

Figure l is a longitudinal -vertical section through the centre of the block on the line jc of iig. 2,V and i Figure 2 is a vertical crossssection on the line y of ig. l. p

My invention relates to certain improvements on the meat-cuttingmachine for which Letters Patent were granted to me, bearing date August 25, 1868, and numbered 81,421, and consists in an improved method of mounting or supporting the chopping or meat-block.

The device consists of a rectangular sliding frame, mounted on the table or platform underneath the chopping-block, which frame, when pushed back, brings the block in the proper position below the cutting-knives, and, when drawn forward, brings the block out from under the knives .in such. a position that the meat can be readily examined or removed, an operation which,

in my previous machine, was vquite troublesome, on

- account of the interference of the knives; and also, in

combination with the said sliding frame, of an adjustable pivot, on which the block turns during the operation of chopping.

A represents the bed or platform of the machine, having secured to its upper side four standards, G, which are placed, two in front and two in the'rear of the main shaft D, and arranged, in relation to one another, as the four corners of a rectangle.

The two rear standards are higher than theothers, and have openings through their upper ends in a direction running lengthwise of the machine; andthe front standards have slots cnt into them from the top, a short distance downward, and running in the same direction as the openings in the rear standards.

On these standards I mount the metal frame F, composed of the two side rails or bars t, connected at their ends by the rods 0, as shown, the side bars of the frame sliding in theV openlngs in the standards before mentioned.

This frame F is greater in length than the distance between the standards, and-may be slid back and forth thereon.

The pivot or standard C, Aupon which the block rotates, is made adjustable vertically, andvis furcated, and sits astride of the main shaft D, as shown in fig. l, and

passing down through the platform A, and being connected to the inner end of a lever, E, pivoted to -the frame ofthe machine at a., the other end of which projects out on one side of the machine, as shown in fig.

2, so that by forcing down the outer end of the lever,

frame F to fall a distance equal to the depth of the.

inclines.

Ou the upper edges of the said side rails of the frame are four points o'r lugs l), which bear or catch against an annular flange on the bottom of the block, (which in this is the inner edge of the ring or plate f, on the outer edge of which are cnt the ratchet-teeth by which the block is rotated,) and thus, when the frame is moved, it moves the block with it.

When the device is to be operated, the frame is drawnv out forward, andthe chopping-block placed upon it in such a position that the lugs b shall be inside of the flange or plate. The frame is then pushed back, carrying the blockwith it over the friction-rollers, and the hole in the bottom over the pivot G, at which point the inclines d will have reached the standards G, and the frame F will drop down clear from the block and leave .it restingupon the rollers. The pivot G is then elevated, and the machine is ready for operation.

The points or lugs l1 always guide the block, so that the hole in its under side shall stand directly over the 'pivot C, so that when elevated it will readily enter.

When the block is to be drawn out, the above oper- ,ations are reversed, fi. c., the pivot C depressed and the frame drawn fbi-ward, when it will rise, and the points l1, engaging with the block, bring it out forward from under the knives.

If desired, any suitable devices may be provided for securing the lever E up or down.

Having thus described my invention,

What I claim, is"- 1. The sliding frame or bars, provided with the inolines, and arranged to slide to and fro on its supports G, in combination with a meat-chopping machine, substantially as and for the purpose set forth.

2. The combination of the adjustable pivot G and sliding frame F, when arranged to operate as herein described.
