IMPROVEMENT IN MEAT-CHOPPERS.

Specification forming part of Letters Patent No. 216,536, dated J une 17, 1879 application led August l, 1878.

` use the same, I will now proceed to describe its construction and operation, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure lis a side elevation with the hopper in section. Fig. 2 is a top view. Fig. 3 is a central vertical transverse section. Fig. 4 is a longitudinal section through the knife-carrier, and Fig. 5 is a top view of the knife-carrier.

In the drawings, Arepresents a cast-ironV base or table provided with legs B for supporting the saine. This table A is formed with a bearing, C, for support-ing a spindle, D, upon which is arranged a suitable driving or operatingcog-wheel, E. This cog-wheel E meshes with a pinion, F, arranged on one of the outer ends of a crank-shaft, G, held by suitable han gers H, formed on the table A, as shown in Figs. l and 3 of drawings.

The table A is provided with two outer guide-bars, I I, and a central double guide-bar, J, the latter passing up through the middle of the hopper K, as shown in Figs. 1,2, and 3 of drawings.

The outer guide-bars, I, are formed with slots L, in which travel one end of the knife-carriers M. The other end of such k :life-carriers is supported in ways N on opposite sides of the central guide-bar, J, as shown in Fig. 2 of drawlugs.

The end of said knife-carriers is supported in thecentral guide-bar, and is provided with a guide-block, c, (shown in Figs. 3, 4, and 5 of drawin gs,) to prevent the knives from oscillating when the machine is in operation.

In some cases only one set of cutting-knives is required, and in view of this, when desired,

the machine may be provided with only one outer guide-bar, I.

The knives O are secured to a curved frame, P, formed with a horizontal piece, Q, and two vertical pieces, R. These vertical pieces R pass up through a slot, S, in the carriers M, receiving a set-screw, T, passing horizontallyY through the carrier M, as shown.

The vertical pieces R are held in the slots S by tightening the screws T. The knives are adjusted by screws u, passing down through the carriers M and against the horizontal pieces Q. These carriers M are operated by pitmen o, which extend down and connect with the crank-shaft G, as shown iu Fig. 3 of drawings.

The hopper is operated by a band, W, which extends from the hub X ot' the operating cog- Wheel E to the pulley Y, arranged on a spindle, Z, supported by a piece, A', of the table A, as shown in Fig. 3 of drawings.

The pinion B', arranged on the spindle, and rigidly connected withthe pulley Y by means of a sleeve, gears with a circular rack-bar, C', arranged on the bottom of the block D', as shown in Figs. l and 3 of drawings.

The hopper K is supported and travels on a circular rim or flange, E', of the table A, as shown in Fig. 3 of drawings.

The crank-shaft G has one end provided with a ily-wheel, F', to balance and make the machine run smoothly.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a meat-chopper, a knife, carrier, M, provided with a guide-block, c, and slotted, as shown and described, to receive the vertical pieces R of the `frame P, a tightening-screw, T, and adjusting-screw u, as set forth.

2. The base A, having an open center, and provided with guides J and L, in combination with guide-blocks c, pitman fu, crank-shaft G, and carrier M, providedwith cutting device, snbstantially as shown and described.

In testimony that I claim the foregoing as my own 'I affix my signature in presence of two Witnesses.

EMMOR W. SILVER. Witnesses:

WALTER F. DEMING, LUomN L. GILBERT.
