Application filed November 21, 1910. Serial No. 593,346.

To all whom it may concern:

Be it known that I, AUeUsT KARHAN, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New York, have invented a certain new and useful Device for Splitting Carcasses, of which the following is a specification.

This invention is a carcass of a beef, etc., along the umn thereof.

The invention embodies novel means, to be hereinafter described, for retaining a cutting mechanism in proper relation with the spinal column of a carcass, and to direct or guide said cutting mechanism as the work of splitting said column progresses.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown there-' in is to be understood as illustrative, only, and not as defining the limits of the invention. w Figure 1 is a side elevation of a power operated splitting device constructed in accordance with my invention, a portion ofv the casing or frame being omitted in order to more clearly illustrate the operating mechanism for the reciprocating cutter. Fig. 2 is an inverted or bottom plan view of the machine shown in Fig. 1. Fig. 3 is a vertical section, taken in the irregular plane indicated by the dotted line 3-3 of Fig. 1. Fig. 1 is a detail view illustrating the opposite side of the driving member from that shown in Fig. 1.

In carrying the invention into practice I employ a supporting frame, indicated in its entirety by A, a cutter head, B, mounted in said frame for reciprocating movement therein, a guide member, C, and power operated means device for splitting the spinal colfor imparting reciprocating movement to the cutter head, the detailed construction of said parts being hereinafter described.

Frame, A, is shown as consisting of two side frames, (1, a, bar a positioned intermediate the side frames at one end thereof, and a handle member, A, which is provided with a barfa said last named bar being positioned intermediate the side frames at the opposite endof the mainframe from the The side frames are fastened rigidly in any suitable way to the bars, a a therebyproducing a small, strong, and compact construction of the main frame. Handle member, A, may be of any sultable or preferred form, and it is attached rigidly to the main frame at one end thereof whereby the handle member is adapted to be grasped and manipulated by hand without liability of the operator being lnjured from the reciprocating motion of the cutter. As shown, the handle member is in the form of a bail, looking'at it in plan, Fig. 2, and it is composed of upper and lower portions which are provided with a plurality of cross pieces, a but it is evident that the form of the handle member may be modified or changed as desired.

The supporting frame is provided with guide ways for the reception of the end portions of cutter head, B, whereby said cutter head is slidable within the frame. As shown, the bars, a of, are provided with grooves,'b, adapted to receive the respective end edges of the cutter head. Said cutter head is provided at its lower edge with plates, 72, 6 adapted for engagement with the respective faces of said cutter head, one of said plates, 6 being secured removably in position by screws, 5 or the like.

D, D, are blades or knives secured to the cutter head for movement therewith. Said blades are positioned between plates, 72, b and they areclamped firmly in position by the plates 2), 6 Blade D is shown as having a beveled edge, d, which is inclined downwardly and inwardly. The other blade,D, is somewhat narrower than blade D, and this blade (D') is providedwith a beveled cutting edge, at, the latter being in clined in an opposite direction to the edge, (Z, of blade, D. As shown in Fig. 1, the edges, d, cl, of the blades converge toward the lower extremity of guide bar, C. The blades are fastened securely to the cutter head, and they are adapted to be removed separately therefrom when it is desired to sharpen said blades, or either of them.

Guide bar, C, is positioned within frame, A, and it extends across said frame intermediate the ends thereof. Said guide bar is secured rigidly to the frame in any suitable way, and it extends through the opening or space provided in the cutter head- The cutter head is slidable with respect to the guide bar and said guide bar is thus adapted to serve as an additional guide for the cutter head. At one end the guide bar is extended beyond the lower part of the frame, said extended part of the guide bar being reduced lengthwise in diameter so as to produce a stem, C. This stem is substantially circular in cross section, and it is uniform in diameter except at its extremity, said lower end of the stem being pointed or tapered, as at 0. The stem of the guide member cooperates with the knives of blades, D, D, so as to serve as guides therefor, and with this end in view said stem is provided with grooves, 0, in opposite sides thereof, as'shown by dotted lines in Fig. l, and by full lines in Fig. 2. The end edges of blades or knives D, D, are fitted slidably in the grooves 0, of stem, C, the length of the stem directing the travel of the knives attached to the cutter head.

Secured rigidly to the upper part of frame, A, is a housing or casing composed of members, E, E, as shown in Figs. 1 and 3. The part, E, of the casing is secured rigidly to the frame so as to form a unitary part thereof, but it is preferred to make the part, E, separate from part, E. One part of the casing is provided with an upstanding post, 6, to which is connected a suspension cable or rope, F, adapted to be attached to overhead means for supporting the splitting device. One form of the overhead supporting means consists of a counterbalance of the character shown in my prior application filed September. 26, 1910, Serial Number 583,736, but obviously the means for supporting the splitting device may be modified as desired.

As shown, member E is provided witha shaft bearing, and with the bearing sleeve, 9. In the shaft bearing is mounted a short shaft, G, see Fig. 4, which is provided with a driving member, H, saiddriving member comprising a beveled gear, h, and a crank disk, h. The gear and crank disk are shown as consisting of separate parts attached rigidly together, but it. is obvious that the disk and gear may be made in one piece. The gear meshes with a beveled pinion, 2', attached to the lower end of a driving shaft, I, and the latter extending through bearing sleeve, 9, whereby the shaft, I, is. adapted to impart rotary motion to the driving member, .H. Shaft, I, may be driven by any suitable means, such as an electric motor, a pneumatic motor, or otherwise, as most desired or convenient. The crank disk of the driving member is provided with a wrist or crank pin, j, to which is attached the upper part of a link, J. Said link extends downwardly from the driving member, H, to thecutter head, the lower part of the link being slotted or bifurcated to produce members, j, which straddle the cutter head and are connected pivotally thereto by a pin or bolt, is.

The operation of the device is as follows: The frame and its contained parts are suspended at its proper height above the floor by cable, F. Shaft, I, is rotated by suitable power connections, or a motor, and this shaft rotates member, H, for imparting re ciprocating motion to pitman, J, cross head, B, and knives or blades, D, D, on said cross head. The cutter head and the knives are guided by the frame and the guide bar,

said cutter head and the knives reciprocating freely withrespect to the frame and the stem of said guide bar. When the carcass is to be split the tail portion of the spinal column isfirst split open by a cleaver or other device in the hands of the workmen, and the carcass is then moved into such a position that my new device will be elevated above the suspended carcass. The operator inserts the guide stem, G, into the spinal cord cavity of the carcass and said device is then'lo-wered for the knives or blades to operate upon the vertebra: of the column. The cutter head and the blades are reciprocated quite rapidly so that the knives will act efliciently in severing the spinal column, the entire device being lowered as the work of cutting the column progresses. The operator is not required to adjust the device centrally with respect to the spinal column, for the reason that stem C, of the guide bearing acts to automatically, determine the position of said device with reference to the column. The carcass may be easily and quickly split for substantially its entire length by my device in the hands of an unskilled workman, it being necessary only to position the splitting device within the spinal column and to lower said splitting device within said column as it issevered by the operation of the cutting mechanism. The handles on the upper and lower parts of the handlemember provide convenient means for the operator to grasp the .implement when it is engaged in the act of cutting the upper part as well as the lower part of the carcass.

It will be observed that the device is light and compactrin construction, that it comprises a comparatively small number of parts, that the driving mechanism is housed or incased in a manner to preclude it from coming into contact. with the carcass, and that the handle is so positioned on the device as to minimize the liability of injury to the operator during the cutting operation, The cutter head and .the knives are retained imposition against lateral displace- .mentby the guides on the frame and by the guiding bar. The knives or'blades act with a draw or shear out upon the vertebrae of the spinal column thereby increasing the efliciency of the. operation.
