MEAT-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 359,069, dated March 8, 1887 (No model.)

which a slide passes, connected by apitman to a crank-shaft; and the obj ect of my invention is to furnish a meat-cutter which combines simplicity with strength, and in which the rotating choppingblock shall stand separate andfree from the actuating mechanism of the knives. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical crosssection of my mechanism; Fig. 2, a top view of the same; Fig. 3, a plan view of the crank-shaft; Fig. 4, a view in elevation of a knife-arm and a vertical cross-section of the box; Fig. 5, a sectional View of a set of knives adjusted in the holder, and Fig. 6 atop plan view ofthe holder.

Similar letters refer to similar parts throughout the several views.

In the drawings, A is the base-frame of my meat-cutter.

B is a circular rest upon frame A, and is provided with groove b.

will rotate the plate C. Upon plate C, andA within drum D, rests the chopping-block E, having center pin, e.

H and H are uprights securely fastened to frame A, to one side of the circular` bottom plate, C, as illustrated in Fig. l of my drawings. These uprights H and II' are iianged vthe adjustment of the blades.

on their inner sides and provided, respect ively, with the top and bottom guide-plates, 7L and 7L', attached to these uprights by setscrews or in any other suitable manner, and thus forming guides.

K and K are slides which slide up and down in the guides formed in uprights H and H, with guide-plates 7i and h.

L is a crank-shaft having the pulleys O and O and the iiy-wheel I. Slide K is connected with crank-shaft L by pitman Q, and slide K by pitman Q'. To slide K is adjustably attached the knife-arm It, and to slide K' the knife-arm R. The adjustable attachment is formed by the slides being respectively corrugated, as shown in Fig. l of the drawings. The knife-arms R and R have corresponding corrugations, and these knife-arms are further providedlwith longitudinal slots,through which screw-bolts pass, by means of which the knife-arms'can be securely fastened to the respective slides, as illustrated in the drawings. lI he knife-arms R and R' extend from the uprights over the chopping-block, and each arm has ou its free end, directly over the chopping-block, a box, fr, a vertical cross-section of which is shown in Fig. 4 of the drawings. Box o' has iu its upper part the set-screw r, and on its side the smaller setscrew,r".

Fig. 5 shows a set of knives consisting of the blades c a: .c and the holder i having neck g/provided with groove s. The base of the holder y consists preferably of two pieces, t and t', as illustrated in Fig. 6, which facilitates These blades r .fr a; have near their tops the slots u u u, and through these slots they are fastened by bolts to the holderi, thus admitting of adjustment to the holder. The neck y of the holder passes in its upper end into the box r, andisadjusted therein by means of the set screw fr. The setscrew r engages with the groove s, thus preventing tbe holder from slipping down. The position of the groove s in holder y determines the angle to which the knives are set relative to the arm.

Pulleys G and O are connected by belt, and a belt also connects the pulley O' with the motor-power for the machine.

The operation of myinvention is as follows: The material to be cut is placed upon chopping-block E. If, now, pulley O is set in mo- IOO tion, it will rotate the crank-shaft L, by means of which, through pitmen Q and Q', the slides K and K' are moved up and down, thus operating the knives upon the chopping-block. By means of pulley O upon crank-shaft L being connected by belt with pulley G, the shaft F is revolved, whereby the chopping-block is revolved, as heretofore described. By means of the adjustment of the knife-arms on the slides, and the neck of the knife-holdersin the box 1, and the blades a' x x to the holder y, the knives can be adjusted to arotating` chopping-bleek of any reasonable depth.

Vhat I claim as my invention, and desire i 5 to secure by LettersPatent, is-

l. In a nieateutter provided with a rotary block, the uprights H H', secured to the baseframe at one side of the rotary blook, lguideplates 7L h', slides K K', knife-arms R R', ad-

zo justably fastened to the slides, crank-shaft L,

and pitmen Q Q', for actuating said slides, the parts being combined substantially as described.

2. A meateutter comprising the frame A, the circular rest B thereon, provided with rim C and oogged on its lower circumferenee, the block E Within the drum D, uprights H H', guide-plates h h', knife-arms R R', provided with boxes r, holders y, blades x, crank-shaft L, having pulleys O O' at opposite ends, pitrnen Q Q', shaft F, having pinion f and gear-Wheel F' thereon, and spindle g, provided with pinion g and pulley G, the parts being` combined substantially as deseribed.
