MEAT-CUTTING MACH-NE.

SPECIFICATION forming part of Letters Patent No. 331,900, dated December 8, 1885.

Application filed February 18, 1884. Serial No. 121,225.

.To all whmn it may concern:

Be it known that I, REUBEN McOHEsNnY, a citizen of the United States, residingin Frankfort, Herkimer county, and State of New York,

have invented certain new and useful Improve-- ments in MeatGutting Machines, of which the following is a specification.

This invention relates to meat-cutting machines in which both the block and the cutters have a rotary movement, and the block is vertically adjustable, so that it may be ad justed toward and from the cutters, as desired, or when it becomes worn.

The objects of this invention are to provide 5 a connection between the cutters and block which will simultaneously and automatically operate both of them; to provide one or more cutters operating at an oblique angle to the face of the block and having a rotary movement around their actuatingshaft, and at the same time an independent and rotary movement about their own axes, or, in other words, what may be termed a planetary movement, and thereby cause the cutters to operate with a shear cut upon the meat or other substances to be reduced by their cutting-edges; to provide a movable frame for the cutters, which may be rigidly locked to hold the cutters in their operative position or swung upon its own axis to elevate the cutters for the purposes of cleaning and repair and for convenience in removing the substances from the block without disturbing or throwing out of action the connections for operating the cutter and the 3 5 block to provide such a connection between the devices for simultaneously adjusting the block and its metal casing that all of said de vices may be simultaneously and uniformly operated; and, finally, to provide certain other 0 details of construction hereinafter described. I attain these objects by devices illustrated in the accompanying drawings, in which Figure 1 represents a perspective of a machine embodying my invention; Fig. 2, a ver- 5 tical section of the same, taken through one of the cutters; Fig. 3, a plan view of the same; Fig. 4, a central vertical section through the same, with the cutters shown above their operative position; Fig. 5, a detail of the cutter and the preferred form of connection between the cutter and its driveshaft to give (No model.)

the cutter a positive and reverse rotary movement.

Similar letters of referenceindicate the same parts in the several figures of the drawings.

A A represent the standards, and B a crossbar, constituting the frame for supporting the operative parts of the machine. The casing O, the rim of which is flaring and projects above the cutting-block, has a closed bottom, having cast therewith or otherwise secured on its under side a short shaft, a, bearing in the crossbar of the frame, said shaft, with its case and the block, being vertically adjustable by means of a screw, D, working in the cross-bar, and having a bearing against the end of the journal of the shaft a. Seated loosely in the casing, and on the set-screws I), is the cutting block E, which may have a plain surface or be provided with acentral projection, 0, against 7Q which the cutters may work, and the meat be prevented from accumulating at this point and out of the operative line of travel of the cutters.

So far means have been described for simultaneously-adj usting the height of the block and its casing; but in order to adjust the block independently of the casing the screws 22 have sprocket-wheel heads 0, connected by a chain 1, so that by pulling on the chain the several screws supporting the block'jarc simultaneously operated,and by this means a uniformity of the adjustment of the entire surface of the block is effectually and quickly secured. These two adjustments of the bloclr provide, first, a means for inovingl tlie ibloclr up ;in contact with the cutters, and, second, for adjusting the block in the casing from time to time as the block becomes worn down from frequent use, and, besides, also provide for a ready removal from the casing of the block to plane it down.

Fixed in and toward the upper ends of the standards is a shaft, F, on which is secured a swinging frame,G, having hooloarms g,which, when the frame is in its operative positiomare adapted to be caughton a rod or round, H, joining the upper ends of the standards, said arms having pivoted thereto weighted levers I, which,.when swung over to their operative positions, embrace the round and operate to removably lock the swinging frame in its operative position, and to maintain the cutter in an elevated position when the frame is swung upon its axis for the purpose of lifting the cutters out of the casing or for cleaning and sharpening them. J ournaled in the swinging frame are shafts J J, which, projecting below the frame, have secured on their ends arms K, which extend at substantially a right angle to the length of the shafts, and have secured toward their free ends and at an oblique angle to the shaft pintles L, on which the cutters M have a loose bearing. Cutters M are cup-shaped, and preferably flaring, so that the operating portion of their edge will exert a force in a line perpendicular to the face of the cutting-block,on whichline they are found to operate most successfully. These cupshaped cutters may be cast in one piece; but by preference their closed end It is cast separately from the cutting-edge,and with a flange to which the blade i may be secured in any suitable manner-as, for instance, by a setscrew.

By making the cup-shaped cutters in two pieces the blades may be made of steel and be readily removed for sharpening or for the substitution of new ones. It should be stated, however, that the cutting-blade may be made in sections, and so also may the entire cutter, and it would not be a departure from this invention to have a hub on the pintle and connect the cutting-blade thereto by radial arms instead of employing a closed head,as shown.

When the shafts of the cutters are revolved by suitable mechanism, hereinafter described, and the cutters are revolved about these shafts with a portion of their cutting-edges in contact with the block, each cutter will describe a circle about its shaft, and owing to itssleeving on the pintle will have an independent movement upon its own axis,by reason of the friction of the cutter on the block. Theblock in the meantime by suitable mechanism, hereinafter described, is revolved in a direction opposite to that of the shafts, and as a result draws upon the cutting-edges of the cutter.

The cutter revolves much slower on its own axis than does the axis of its shaft, and this slow movement, in connection with its drawing upon the cutting-block, causes the cutter to operate or make a shear-like cut, so that the meat or other substance operated upon is drawn down against the cutting-edge, and not pushed forward, as it would be if the cutter were rigid upon the pintle or operated direct from the shaft. In order to render this shearlike cut more positive,the cutter may, as shown in Fig. 5, be made rigid on the pintle, and the pintle have a loose bearing in the arm, and have secured on its projecting upper end a gear, j, meshing with a gear, 70, fixed to the cross-bar of the frame G, and by this means the cutter be revolved in the opposite direction to its shaft, thus insuring a draw out downwardly upon the material being operated upon.

By the peculiar action of the cutter, and especially upon meats, a clean sharp cut is always made, and there is no lost motion in the operation of the cutters, while at the same time the crushing or bruising of the meat fibers is entirely avoided, and the cutting capacity of the machine materially increased.

I have shown in the drawings a machine provided with two cutters; but it is obvious that a greater or less number may be employed, as desired, without a substantial departure from the spirit of my invention.

In order to prevent the cutters from clogging, they are each provided wit-h a cleaner, N, consisting of a bent strip of metal secured at its ends to the pintle both above and below the cutter-head, which cleaner is preferably of spring metal, and is bent around both sides of the cutting-blades and of the cutting-edge thereof without being brought in actual contact with said blade; but so far as the invention involved by the cutter and its actuating mechanism is concerned it would not be a departure from my invention to have cleaners of any other desired form or manner of operation, though I consider the form of cleaner shown as preferable. The cleaner, however, should be fastened to some movable portion of the mechanism for actuating the cutter-as, for instance, the pintle-armelse the cleaner would move down between the cutter and the block, and of course ruin the cutter; but if IOO operated upon by the machine, and to throw v it constantly in the path of the cutters, a stirrer, 0, Fig. 4, may be secured to the rigid round of the swinging frame at any point which will cause it to effect the best results.

As shown, the mechanism for actuating the cutter or cutters consists of a sheave, Z, secured to the cutter-shaft, and connected by belt p with a large sheave, m, on a vertical shaft, 0, which by means of a belt is connected with a sheave, p, on a vertical shaft, q, the case and block being actuated by means of a belt, r, laid in groove 8 on the periphery of the case, near its bottom, which belt engages with a sheave on the upper end of the short shaft g. In practical use, however, I propose to employ shafts and gearing connecting with some motive power, and thereby dispense with the sheaves and belts, which are only shown for the purposes of illustrating the operation of my machine.

It may be proper to add that the velocity of the cutting-block should be less than that of the cutter-shafts, and substantially that of the cutters upon their own axes, for obtaining the best results.

The stirrer, instead of being a single blade, may consist of two or more tines, like that of a fork.

IIO

up or down in the arms, and by so doing de crease or increase the diameter of the circle on which the cutters are operated, for it will be seen that if the pintle is raised the cutters will move in a less circle than if the pintle is lowered in the arm.
