SPECIFICATION forming part of Letters Patent No. 313,356, dated March 3, 1885.

7 Application filed May 21, 1884. (No model.)

To all whom it 11mg concern: v

Be it known that l, VVILLIAM MoOoNNELL MATHES, of Gatesville, Coryell county. in the State of Texas, have invented a certain new and useful Improvement in Meat-Choppers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a machine for either tendering or mincing meat. It is for hand use, and automatically changes the position of the meat beneath the vertically-reciprocating knife or tendering-blade.

Figure 1 is a side View. Fig. 2 is an end view. Fig. 3 is a top view. Fig. 4 is a vertical section at 4 4:, Fig. 3. Fig. 5 is a detail transverse section showing a tendering blade or device secured to the sash in place of the knife.

a is the frame of the machine. I) is the movable carriage or meat-board carried between supporting-rollers c and steadying-rollers d. Beneath the meat-board are two racks, 6, whose teeth engage pinions f upon a shaft, g, that carries at its end aspur-wheel, h. iis abandcrank, whose shaft 1" carries a spur-wheel, j, that engages with the wheel h, and a spurwheel, j, that engages with a pinion, is, upon a crank-shaft, Z, by which the sash is actuated. The crank m of the shaftl is connected by a pitman or rod, n, with the sash o The sash works vertically in guides 19 of theframeo.

The sash is formed for the attachment of the knife or tenderer r.

I propose to secure the blade to the sash in the following manner: sis a horizontal tongue ofthe sash, that fits in a groove, t, of the blade, so as to prevent all vertical movement of the blade upon the sash. The blade r is held firmly upon the tongue by clips u, held by screws o.

w are wires or rods extending across the machine parallel to the knife or tendering-blade r. These wires or rods are movable. so that they may be arranged in close proximity to the sides of either theknife or tenderingblade. As the former is thinner than the latter, it is obvious that the rods or wires would require to be movable for the purpose stated. The office of these wires is to prevent the blade r from carrying the meat upward with it as The wires or rods w have heads board to pass beneath the blade, and at the same time causes the vertical reciprocation of the sash and knife or blade r. The knife may have sufficient depth to cutdown to the board, and thus mince the meat. On the other hand, aknife of less depth will not cut the meat quite through. so as to merely score the meat. Thedepth of cut would thus depend on the depth of the knife.

WVhen it is preferred to bruise the meat, instead of scoring or cutting it, a plain or serrated blade or bar, r, is used in place of the knife 9", (see Fig. 5,) the wires or rods to being set a sufficient distance asunder to admit the passage of the tenderingblade between.

It will be seen that by the oscillation or rotation of the haudcrank any partof the meat may be brought beneath the sash and operated upon as much as may be desired.

The relative speed of movement of the sash 0 and meat table or board may be regulated by changing the spur-wheels for others of different size. Thus the spur-wheel may be "changed for one larger and wheel j for one smallerin diameter than shown to decrease speed of thesash.

I claim as my.i nvention 1. The combination of the frame having horizontal slots :0, a sash-having interchangeable cutting and tenderingblades, devices for operating the sash, and wiresor rods 10, adjustable in said slots to accommodate either blade. as set forth.

2. The combination of shaft 11 with spurwheelsjj, pinion 7c. crank-shaft Z, pitman n, sash 0, removable blade 1". shaft 9, carrying spur-wheel h and pinions f, and meat board or table I), with racks e, substantially as and for the purpose set forth.
