IMPROVED MEAT-CHOPPER.

TO WHOM IT MAY CONCERN:

Be it known that CALVIN A. FOSTER, of Winchendon, in thejState of Massachusetts, invented certain new and useful Improvements in Machines for' Ohopping Meat, of which improvements the follo'wingis hereby declared to be a full. clear, and exact description, reference being had to the accompanying drawings, in which v Figure 1 is a side elevation of a machine constructed in accordance with his invention.

Figure 2 being a longitudinal section, and

Figure 3 a top view of the same.

The machine to which. the improvements, the subject of this application, are applied is one in which one or more vibratory cutters having a descendiug and transverse or ill-aw" stroke are combined with a tub or block which contains the material to be cut; .The invention relates, first, to the method of effecting the rotation of the tub, and, secondly, to the arrangement and combination of the cutters and their operative mechanism, and it'essentially consists iu 1. The combination, with the vibratory cutters having a draw'stroke, of a tub and suitable mechanism for rotating the same in such manner that the rotation shall be effected intermittently and while the cutters are lifted from the bottom of the tub.

2. Forming the frame of the machiue in two parts-one stationary, the other swinging or movable-the two being connected by a horizontal hinge-joint, or its mechanical equivalent.

The advantages arising from the first-mentioned feature of the invention are apparent, and therefore need not be recited here.

The method of forming the frame of two parts, hinged or otherwise suitably connected together, which constitutes the second'feature of the invention, admits of the vibratory cutters and such other of the parts which overhang or are contained within the tub, being so combined with the movable part as that they may be bodily lifted from the tub when occasion requires. By this means readyaccess may be had at all times to the contents of the tub, which contents can be handled or removed with facility, or the tub itself, if it be desired, can be lifted out from its seat, the cutters and other overhanging parts being swung or tilted back so as to be entirely out of the way, The steadiness of the machine, whcn the cutters are operating, is insured by means of a locking device, which holds the two parts of the frame firmly and tightly together.

To enable others skilled in the art to understand and use the invention, the manner in'which the same is or'may be carried into effect will now he described by reference to the drawings accompanying and forming part of this specification.

In the drawings, A denotes the sustaining frame of the machine, and B the main or driving-shaft carrying the fly-wheel E, and rotated through the medium of a pinion, C, which engages with an internal gear, D, mounted on one of the posts a a of the frame. By turning the gear D by means of a crank, 6, extending from such gear, thedriving-shaft will be put in revolution. Fis the tub, and G G the two chopping-knives. Each of such knives, in its operation, is moved up and down and forward and backward within the tub, whereby it is made to cut with a drawing stroke any meat when in the tub. The shank c of each knife is fastened in one of two bent levers or carriers, H H, formed-as shown in the drawings. At its rear end each of-the said. levers is jointed to one of two cranks cl (1, extending from the driving-shaft, one of such cranks being what is termed a bell-crank. At or near its middle each of the carriers is also jointed to the upper end of one of the rockerarms are, whose lo wer ends are jointed to the movable part of the frame hinged at its rear end to the shaft-post a, so as to be capable of being turned up in a vertical plane. When down in its lowermost position the arm rests on a step or bearing, f. A post, 5 extends upward from the frame A, and when the arm is on the step f such post 9 projects through an aperture made in the said arm. A turn-button, it, applied to the upperend of the said post, serves to enable the arm to be held down upon the step. The cap or cover 2' of the tub is also secured to the arml by means of a rod, 7c, extending from the cover and into a post, Z, on the arm, such rod being fastened to the post by a set-screw, m. The plough K of the tub is also attached to an arm, on, extending from the swinging arm or frame I, or is inserted in a socket applied to it, or to a guardplate, n, attached to the said frame.

, From the above it will be seen thatwhen the movable frame is lifted or swung back, such 'frnme will not only raise the-knivesand the plough out of the tub, but at-the same time will raise the segmental cover iaway from the tub so its to uncover it. The said cover is to be formednvith slots or passages, a 0, for'the knife-shanks to go through. The tub is supported on a. cross,p, which revolves on a pivot, q, and-has an interior ratchet, r, fixed to its underside concentrically with the pivot q. A'draw-pawl, 8, applied to the ratchet, and pressed toward it by a spring, t, and arranged as represented, has its rear endjointed to the shorter arm of a bent lever;

- "It, tvhichturns verticnllyon a fulcrum, v, extended from the post g. The longer arm of the leveru'is jointed to the connector '11, which,.in turn, is jointed to an arm; 11), projecting from one of the carriers H H. A small stud, w, extends down, from the bottom of the tub, and by contact with the edge of one of the arms of the cross, causes the cross, while in revolution, to revolve the tub. When the machine is in operation the vibratory motion of the carriers H causes aback and forth movement of the pawl and its actuating mechanism, and consequently eflects the intermittent rotation of the tub. The arrangement of the mechanism is such, as shown in the drawings, that the rotation of the tub only takes place during the interval between the stroke of the cutters and while the knives are removed from contact with the tub.

Whatis claimed as the invention of the said CALVIN A. FOSTER, is as follows;

- 1..The combination, in a meat-chopping machine, with a vibratory cutter or cutters having a descending and transverse stroke, of a tub, andmechanism for rotating the same intermittently, 2'. 0., during the intervals between the strokes, or while'the cutter or cutters are lifted off the bottom of the tub.

2. Forming the frame in two parts-one stationary, the other movable-the two being connected together by a horizontal hinge-joint, or its mechanical equivalent. I

3. In a meat-chopper frame, composed of two parts united by a hinge-joiut, as described, the combination with the movable part thereof pfthe vibratory cutters and such appurtenances of the machine as overhang or are held within the tub, so-that the said cutters .and a ppurtenanc'es may be bodily lifted out of. the tub. as and for the purposes described.

' 4. The combination with the stationary and movable frames of the locking device.

In witness whereof I, M. W. TERBILL, President of the Metropolitan Washing Machine Company, acting for and in behalf of the said company, have hereunto set my hand before two subscribing witnesses. l
