TATES THE MEAT-CUTTER.

SPECIFICATION forming part of Letters Patent No. 545,785, dated September 3, 189 5.

Application filed March 20, 1895; Serial No. 542,519. (No model-Y which the following is a specification.

My invention relates to improvements in meat-cutters, and the main objects of my improvement are to increase the efficiency and durability of the machine and to provide for the more convenient and better adjustments of the parts.

In the accompanying drawings, Figure 1 is a perspective view of my meat-cutter. 2 is a central longitudinal section of the same with the screw-adjusting rod in elevation. Fig. 3 is an end view of the screw or combined forcer and cutter. Fig. 4 is an elevation of the knife, showing its inner side. Fig. 5 is a side elevation ofone part of the case, showing its inner side; and Fig. 6 is a plan view of a portion of the perforated plate.

My invention isin the nature of an improvement upon the 1neat-cutter patented to Amos Shepard,April19, 1892, No. 473,166, and is substantially the same in its general form; but I have made such changes in the construction thereof as to adapt it for use in connection with a perforated plate and knife, while at the same time I provide a new adjustment for the knife that works against said plate, which plate and knife are also applicable to other meat-cutters.

On the delivery end of the two parts A B of the longitudinally divided and separable case I form an inwardly-projecting ledge 7, holding said parts together by the clamp-like standard C, Fig. 1. I also provide one of said parts, preferably the part A, with a steadypin orlug 8, adjacent to said ledge 7, as shown in Figs. 2 and 5. These parts A B may be otherwise substantially the same as in the aforesaid patent, with the long and short feeding-ribs 9 10 and series of cutting elevations 11, with spaces between, as shown in my Fig. 5.

The combined forcer and cutter, which for convenience I will call the screw D, is made to fit the case, and is provided with a shank or shaft-like projection 12, for the attachment of any suitable crank, as shown by the crank end 13, the crank being represented as broken oif in order to economize space. This screw is bored through longitudinally, with a portion of the bore threaded and a screw-adjusting rod 14 screwed therein, as shown. In the center of the delivery end of the screw I form an angular socket 15. A perforated plate E, preferably of disk form-that is hav ing two like sides is placed between the two parts of the case, just inside the ledge 7, and with the pin or lug 8 projecting into the notch 16, Fig. 6, of said plate. Inside of said perforated plate is a knife 17, with any desired number of arms, preferably four, and an inwardly-projecting angular hub 18, which is fitted loosely to and rests within the angular socket in that end of the screw.

After use the principal parts will be separated for cleaning. When it is desired to use the machine again, the knife-hub is placed within its socket; at the end of the screw D, the screw and knife together placed within one of the parts of the case, preferably the part A, the perforated plat-e placed in position between the ledge 7 and the knife, and with the notch 16 in engagement with the pin 8, the other part of the case put on over the screw, knife, and plate, and the whole secured within the standard. The crank may not have been taken off, but if so the knurled head of the screw-adjusting rod 14 issmall enough so that the crank can be put on without removing said rod. This rod is then turned to force the knife properly against the perforated plate. The same act will alsohave a tendency to force one side of the cutting elevations on the case and engaging side walls of the grooves in the screw into active engagement, even if the two parts of the case have not been firmly bound upon the screw or in case they are worn so as not to fit. The action of the screw and case on the meat is the same as in the aforesaid patent, the first part of the screw near the hopper forcing the meat along, while the cutting elevations of the screw and case act to cut the meat to a greater or less extent, dependent upon the number of cutting elevations and the pitch of the grooves and ribs on the screw. The pitch at the cut ting elevations can be varied at pleasure to obstruct the flow of the meat or to let it flow ICO more rapidly. After passing the end of the screw the meat is further reduced by the action of the perforated plate and the knives bearing thereon; In this machine the screw is firmly held in its bearings by being bound at its peripheral portion by the two parts of the case, so that it cannot rock to make the knife-accommodate itself to the face of the perforated plate.

By having the knife arranged as described, with the rounded end of the screw-adjusting rod bearing on the end of its hub likea pivot or step, the knife is free to rock and accommodate itself to the inner face of the perforated plate, so as to insure a good cutting bearing thereon at all points.

I prefer in all cases to employ a case and screw which shall materially cut the meat before it reaches the perforated plate, as meat so out is believed to run through the perforated plate more readily and with greater ease than when the perforated plate and knife alone are depended upon to do the principal cutting; but it is evident that while my improved plate and knife are particularly adapted to co-operate with the particular screw and case herein described, the construction is also adapted to an ordinary forcing-screw and case in which the principal cutting is done by the perforated plate and its knife. I also prefer to make the angular knife-holding socket in the end of the screw and the angular hub as a projection on the knife; but the projection and socket might be reversed and have the same screw-adjusting rod act in connection therewith.

I claim as my invention- 1. The combination of a meat cutter case, its screw, the knife fitted thereto by an engaging angular recess and projection, the perforatedplate and the screw adjusting rod extended through said screw for forming a step or pivot upon which the knife may rock, substantially as described and for the purpose specified.

2. The combination of a two part longitudinally divided and separable case having cutting elevations near its delivery end, said case being extended beyond said elevations, a combined forcing and cutting screw having cutting elevations extended to and running out at its delivery end, said end being fitted to said cutting elevations and supported axially by means of the peripheral bearing contact therewith in contradistinction to being supported in plain bearings, and a perforated plate and knife made separately from said case and screw but attachable to and detachable from the same and confined within the case in the space between the delivery end of said screw and the delivery end of the case, substantially as described and for the purpose specified.

3. The combination of a longitudinally divided and separable case having a series of cutting elevations, a combined forcing and cutting screw having a series of peripheral grooves in bearing contact with said elevation, a perforated plate and knife, and an adjusting device for forcing-said plate and knives against each other and at the same time forcing the cutting elevations and grooves of the screw and case into engagement, substantially as described and for the purpose specified.
