MEAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 643,549, dated February 13, 1900.

Application filed June 19, 1899. Serial No. 721,116. (No model.)

supported perforated cutter-plate with which an internally-arranged revoluble cutter-knife coacts. Heretofore in cutting-machines involving these elements the outer perforated movably-supported cutting-plate has been' supported at its edge either by a ring or the equivalent device engaging the edge thereof. In this previously-arranged construction in order to prevent a binding of the parts in operation it has been necessary to have the revolving cutter-knife and the edge-supported perforated cutting-plate strictly parallel, which necessarily increases the cost of production,as will be readily understood by those skilled in the art.

One object of my present invention is to avoid the necessity of having the knife revolve strictly parallel with the plate and to avoid the necessity of having the central bearing strictly at right angles to the cutting-knife by permitting the perforated cutting-plate to have a wabbling movement, and thus enable it to work right up to the severing edge of the internally-arranged knife Whether that knife and its shaft run perfectly true or not.

In the accompanying drawings, Figure 1 is a perspective view of a cutter embodying my invention. Fig. 2 is a horizontal longitudinal sectional view through the cylinder, looking from above. Fig. 3 is a detached perspective view of the clamping-bar for the perforated cutting-plate. Fig. t is an enlarged crosssectional View on the line 4 at of Fig. 3.

Referring now to the drawings, A is the standard, carrying at its upper end a horizontal tapered cylinder B, which has communicating with one end a hopper O and an open outer flanged end D. The interior of this cylinder B is provided with a spiral rib, and passing through the cylinder is a spirallythreaded forcing-shaft E, both of which may be of the usual construction. One end of this forcing-shaft passes through the rear end of the cylinder B and has connected therewith in any desired manner an operating-handle F. The outer end of this forcing-shaft E is provided with a knife, preferably composed of a laterally-projecting flange G, which in turn is provided with a plurality of openings H, the edges of the said openings forming cutters which coact with the inner edges of the openings I in the outer perforated coactin g cutterplate J. This cutting-plate J is loosely supported within the flanged end D of the cylinder B and has its inner face resting directly against the said cutting-flange Gof the forcingshaft. For the purpose of holding this perforated cutting-plate J in contact with the outer face of the cutting-flange Gand in such a man- 'ner as to permit the said cutter-plate to rest closely against the outer face of the knife or cutting-flange and to work close thereagainst irrespective of any wabbling of the said outting-flange, owing to any irregularity in its thickness or owing to any unevenness thereof, which may arise from several causes-as, for instance, the bearing of the shaft not being absolutely true, or the cutter-flange not being absolutely true in respect to the shaft, or the end'of the cylinder against which the inner face of the cutter-flange rests not being absolutely true, in which event the outer perforated cutter-plate J will bind the machine unless it is supported in a manner to allow it to follow any untrue movement of the cutter-fiange l provide for this contingency by holding the cutting-plate J against the outer face of the cutting-flange G at a central point in contradistinction to supporting it at its edges. This arrangement permits the plate J to follow and to work closely against the outer face of the cutting-flange at all times and avoids the necessity of accurate work in the construction of the machine, and thus cheapens the production thereof.

The cutterplate' J is held by a transverse bar K, which is pivotally supported at one side of the end of the cylinder B-as, for instance, the point L-whereby it can be swung from across the face of the plate J to permit its removal, as indicated in dotted lines, Fig. 1. The opposite end of this clamping-bar K is provided with a slot M, adapted to receive a screw-bolt N, passing into a laterally-projecting ear P upon the flanged end D of the cylinder. The inneredge of this clampingbar K has at its center an inwardly-projecting portion Q, adapted to engage the central portion of the plate J and form the only means of holding the plate against the cuttingflange G. This arrangement, as will be readily understood, enables me to clamp the cutting-plate J against the outer face of the cutting-flange G with the desired amount of tension or friction, while at the same time it will permit the cutting-plate J to follow any untrue movement which the cutting-flange may have. This construction is found by me to be very advantageous, for should anything work between the inner face of the cuttingfiange and its seat against the end of the cylinder it will not alfect the operation of my machine, for the plate J will conform its position to that of the cutting-flange, whereas in constructions heretofore devised which support the cutting-plate J from the edge such a condition would at once wedge the machine and either absolutely stop the operation of the machine or, should the machine be forced,would causeaseriousinjury thereto.

From the above description it will be noted thatin addition to so clamping the cutter-plate J as to permit it to follow the untrueness of the cutting-flange I also provide a clamping means that enables the parts of the machine to be quickly removed for the purpose of cleaning as compared with a screw-ring, which not only has the disadvantage of requiring accuracy in the construction of the machine, as heretofore stated, but also requiring carefulness in the replacing of the screwcap when it has been removed and which requires more time in removing and replacing than is required with a clamping device such as that I have shown and described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A cutter of the character described comprising a cylinder, a forcing-shaft therein, a knife connected with said shaft, a cutter-plate loosely supported at the outer end of said cylinder and engaging the outer face of said outter, one of said cutting members being rotatable, and a clamping member carried by the cylinder and engaging the said cutting-plate at its center, substantially as described.

2. A cutter of the character described comprising a cylinder, a rotatable forcing-shaft therein, a knife carried by said shaft at the outer end thereof, a cutter-plate loosely supported outside of said cutter and engaging the outer face thereof, one of said cutting members being stationary and the other relatively rotatable, and a clamping member carried by said cylinder and having an inwardly-extending central projection engaging the center of said cutter-plate, substantially as described.

3. A cutter of the character described comprising a cylinder, a rotatable forcing-shaft therein carrying at its outer end a knife, a stationary cutter-plate r'novably supported out-side of said cutter and engaging the outer face thereof, and. a clamping member loosely supported at one side of the end of the cylinder, having a central inwardly-extending projection engaging the center of said cuttingplate, the cylinder carrying a clamping member, and the free end of this clamping memher having an open-ended slot adapted to engage the said clarnping member, substantially as described.

4. A cutter comprising a cylinder, a rotatable forcing-shaft therein carrying at its outer end a knife, the outer end of the cylinder constructed to receive a cutting-plate, a relatively-stationary cutting-plate loosely seated therein and engaging the outer face ofthe' knife, the end of the cylinder having oppositely'disposed projections, a clamping member pivoted at one end to one of said projections, said clamping member having an inwardly-extending central projection engaging the center of the cutting-plate, and a clamping-screw passing through the opposite end of said clamping-bar and into the other oppositely-disposed projection of the cylinder, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
