ROCKING MEAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 433,056, dated July 29, 1890.

Application filed February 2l, 1890. Serial No. 341,283. (No model.)

T0 all whom, it may cm1/cern:

Be it known that we, PETER J. TERNES and ROBERT IIOHNBACH, Jr., of Milwaukee, in the county of Milwaukee, and in the State of Tisconsin, have invented certain new and useful Improvements in Rocking Meat-Cutters; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to rocking meat-cutters; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter, and subsequently claimed.

In the drawings, Figure l is a vertical longitudinal section of our improved meat-cutter with parts broken away and other parts in dotted lines, Fig. 2 is a plan view of the same, partially broken away and partially in section. Fig. 8 isa plan View of the mechanism for raising and lowering the meat-block, on an enlarged scale, parts being shown in section or broken away to better illustrate details of construction; and Eig. 4 is a detail sectional view on the line i et of Eig. l.

A is the base, from which rise two standards or upright frames B B, which support the power-shaft C, the latter being provided withl pulleys a a and a worm b, as shown. The worm b meshes with a horizontal worm-wheel c on the upper end of a vertical shaft D, which is steadied in upper bearings d on the end of a bracket-arm e, projecting from one of the frames B. This shaft at its lower end is stepped in lower bearings f, just above which said shaftcarries a belt-pulley g for rotating the meat-block E, as hereinafter explained.

F F F are a series of standardspreferably four in number, rising from the base A, to which they may be secured, as shown, by nuts h, passing through the base-flanges i of said standards. The tops of the standards E E are perforated for the reception of the hubs j of screw-bolts G G G', which carry horizontal sprocket-wheels 71;, mounted rigidly thereon above said standards. Fastening-collars k surround these bolts near their lower ends, just below the tops of the standards F F F, and the standard F is shorter than the others and supports the hub of a horizontal handwheel II. This wheel is mounted on the screwbolt G just below the sprocket-wheel k, so

that all of said sprocket-wheels may be on the same horizontal plane, and the said wheels are all connected by an endless sprocket-chain I, as shown.

J is a bridge or arch standard, also rising from the base A, and preferably secured thereto by nuts 7i,passin g through the lower flanges t" of said standard. This standard is provided with a central socketjl for a vertical spindle K, which is preferably hollow, being thus equally strong and inexpensive, and after passing downward through the socket j the spindle receives and passes through a horizontal pulley I', suitably secured to the spindle beneath the arch-standard J. The end of the spindle is stepped into a socket 7'2 in a short standard J which rises from the base A beneath the centerof the arch-standard J. The lower extremity of this spindle preferably rests upon a steel button g in the bottorn of the socket y2, which serves to decrease friction and wear, and the spindle has an eccentrically-secured top K', also preferably hollow for the sake of strength and cheapness. This top K is suitably secured by a key f', for example, to a circular casing II', having` an upper horizontal iiange or flanges e', by means of which and nuts and bolts CZ c the said casing is secured to the under side of a circular plate E. This circular plate supports the meat-block E and has a circumferential. vertical flange b', provided at equidistant points (preferably four in number) with transverse screw-threaded perforations to receive screw-bolts a', as shown. These bolts have brake-shoes a2 at their inner ends, said shoes being concaved to conform to the adjacent surface of the meat-block, and at their outer ends said screws have handles or thumb-pieces b2 at lthe other end, whereby the said meat-block may be centered or adjusted on its supporting-plate and securely held in the desired position.

The supporting-plate E of the meat-block is itself supported as follows: L is the hub of a spider having a series (as four) of anged arms L L. This hub (in the position of parts shown in Fig. l) rests on top of the standard J and said arms, after extending horizontally for the greater portion of their length, curve IOO upward at their ends, as best shown in Fig. l, and are provided at their 'extremities with depressions and seats Z Z2 for Van tifriction rollers m and their j ournalsm said arms beingtran sverselyand vertically perforated, as shown at fm m, for the passage therethrough of the vertical screw-bolts G G. The lower part of said perforations 'm m are enlarged and provided with polygonal faces for the reception of nuts n fa, so that the upper portion of said perforations m may be smooth, thereby reducing the cost as compared with screw-threading the perforations through the arms L L. These arms with their hub L may be simply cast in one piece complete, the nuts n receiving the screw-bolts, while the supporting-plate E of -the meat-block, which may have an annular bottom 11e-enforce n', if desired, rests squarely and evenly on the anti-friction rollers m m. A belt M connects the pulleys I and g and transmits power from the vertical shaft D to the said spindle K, all as best shown in Fig. l.

N N represent ily-wheels mounted on the ends of the power-shaft C outside of the upright frames B B, and these wheels are pivotal'ly connected by meansof wrist-pinso on their .peripheries and rods O O to the knife-frame P of our device, as follows: The said frame,

vwhich is preferably an open and practically other halfof the bolt o2Y islarger than the part o and fits a corresponding perforation through the rod O, said pivot-bolt having a solid collar p3 between its parts o o2, and screwthreaded ends which receive nuts p p2. The end which receives the nut p2 is preferably reduced in diameter, and has a washer o3 interposed between said nut p2 and the part o2 of the said pivot-bolt. Beyond this point of connection with the said pivot-bolt the rod O is continued at O', and is provided near its extreme free end with a pin Yq, designed to travel time, if desired, as w ien cleaning or repairing the machine.

R R R represent a series of knives having convex cutting-edges adjustably suspendedv from the knife-frame P by means of hangers S S, oneat each end of each knife. These hangers have shanks passing through screwthreaded perforations in the sides of the frame P and bifurcated lower ends s s, which straddle the backs of the knife-blades, said ends being bolted or riveted thereto. Nuts s cured on the knife-frame P. M is a gravity-V catch, also pivoted to the said frame B and serving to hold and lock the arm T of the leverin the position shown. We have also shown a perforation u in said lever-arm and another u in the frame B, and when these perforations are brought into register with each other the adjacent side of the knifeframe will be raised, and by slipping a pin through both of said perforations the parts can be locked in that position.

When deemed necessary, one or more additional curved guides, such as is shown in dotted lines at U in Fig. l, may be attached to any convenient part of the frame-work of the machine-such as the upright frames B- the said guide or guides U projecting in a direction opposite that of the guides Q, already described. The guide U is much longer than the guide vQ, and is provided with a curved slot V, similar to the slot q. To render saidV guide or guides U eifective, there must be for each guide an extension WV on the knifeframe P and a pin X on said extension Working in the said slot V, all as shown in Fig. l in dotted lines.

The operation of our machine will be readily understood from the foregoing description of its construction. Vhen power is applied to the shaft C, the fly-wheels N revolve, and by means of the rods O, wristed thereto and pivotally connected to the knife-frame P, the latter, with its knives, is given a rocking motion, this motion being controlled by means of the engagement of the rod-extensions O and curved slotted guides Q, (as well as the engagement of the parts U V W X, if the same be used,) as the said knives rock on the meat-block E. The latter is rotated eccen trically by means of the described construction and connect-ion of parts, thereby con stantly changing the position of the meat upon said block.

A very important feature of the invention is the construction described, whereby by simply turning a hand-Wheel the meat-block will be automatically and evenly raised or lowered, the described slotted guides and attachments absolutely preventing the knives from accidentally slipping out of proper position.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In a 1neat-cuttingmachine,a meat-block- IOO IZOA

trally to its under side, in combination with a Vertical driving-spindle carrying at its upper end an eccentric top piece connected at one side to one of the sides of the said socket, substantially as described.

2. In a meat-cutting machine, a rocking knife-carrying frame having an upwardlyextending standard and an upwardly and inwardly extending longitudinally slotted guide-arm secured at its base to said knifecarrying frame, and an actuating rod or link Working at its end in the slot of the guide-arm and pivoted back'of said end upon the standard, substantially as described.

3. In a meat-cutting machine, a prolonged cylindrical socket attached centrally to the under side of the meat-block and a vertical actuating-shaft having an eccentric top piece workingwithin said casing, a number of vertical lifting-screws engaging the block and carrying sprocket-Wheels, an endless chain connecting said wheels, and a hand-wheel mounted upon one of said screws, substantially as described.

4. The combination, with a rocking knife-y carrying fraine and a bent lever connected at one end to the frame and pivoted upon the power-shaft standard, of means, substantially as described, for retaining the outer end of said lever in raised and depressed position relative to the shaft-standard, as set forth.

5. In a rocking meat-cutter, the combination, with a series of standards and vertical screw-bolts passing therethrough and carrying sprocket-Wheels in horizontal line with each other, of an arched standard having a central socket, a spindle passing therethrough and carrying a horizontal pulley and terminating in an eccentrically-secured top, a cylindrical socket, surrounding said top, a circular plate secured to said casing, a meatblock resting on said plate, a spider having arms provided with anti-friction rollers supporting said plate and perforated and carrying nuts for the reception of the said screwbolts, a sprocket-chain engaging with and connecting all of said sprocket Wheels, a power-belt on said pulley, and a hand-wheel on one of said screw-bolts, substantially as set forth.

In testimony that we claim the foregoing wc have hereunto sct our hands, at Milwaukee, in the county of Milwaukee and State of XViscOnsin, in thc presence of two witnesses.
