LOUIS F ADUM, OF BALTIMORE, MARYLAND.

MEAT-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 363,512, dated May 24, 1887.

Application filed October 18, 1886. Serial No. 216,490. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS FADUM, a citizen of Germany, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in MeatCutting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in meat cutting machines wherein I employ three rotating knives which are attached to one shaft, a shearing-edge for one of these rotating knives being provided in a stationary or fixed knife and shearing-edges for the two other rotating knives being formed by por-.

tions of the frame-casting. The said rotating knives are constructed with their edges so beveled that in the rotating movement of the knives these beveled edges serve as a screw to force the material from one knife to the other. and thus make a continuous feed through the The frame and a portion of the hopper are in one casting, the hopper being completed by a front plate. These two parts are held together by the shaft and nuts. Thus by removing the nut from either end of the shaft the said two parts may be separated and the entire device gotten at for cleaning.

In the further description of my invention reference is had to the accompanying drawings, in which Figure 1 is a front elevation in full of the machine. Fig. 2 is asection through the center of Fig. 1. Fig. 3 is a plan of Fig. 1 with a portion of the front plate cut away. Fig. 4 is a front elevation of the hopper with the front plate removed, showing the inside knives. Fig. 5 is a detailed view of one of the knives. Fig; 6 is a section through the line as x of the knife, showing the beveled edge. Fig.7 is a front elevation of the stationary knife, and Fig. Sis a side elevation of said knife.

' Similar figures refer to similar parts throughout the several views.

The figure 9 denotes the frame,whi ch forms a portion of the hopper 10, and is provided with the legs 11 for the necessary foundation, the said legs being joined by the portion of the frame 12in which is the slot 13, by which means the device may be secured to the table ,by a clamp and readily put in position or removed. On the frame 9 is the boss 14, which forms the necessary bearing for the shaft 15. The figure 16 denotes the front plate, wh ch forms the remaining portion of the hopper and provides the other bearing, 17, for the shaft 15.

Rotating freely within the device is the shaft 15, which is operated by means of the hand crank 18, the end 19 of the said shaft being tapered in the manner shown in Figs. 1 and 2. On this shaft 15 are secured the knives 20 21 22, the said knives being provided with the tapered and oblong opening 23, Fig. 5, corresponding to the taper of the shaft, which serves to insure each knife being placed in its proper position on the said shaft. The knives 20 and 21 are further provided with the beveled edge 28, which serves to force the material from one knife to the other.

In the rotating movement of the knife 20 it passes close to the projecting surface 24 of the frame 9, which makes a shearing-edge, the

form of the hopper causing the material to fall in the path of the knife 20 on the shearing-edge 24, thus making a cut at this point.

Between the knives 20 and 21 is placed the stationary knife 27, which is made stationary by its lower leg fitting in the slot 25, with which the frame 9 is provided, and held therein by the front plate, 16. Through the center of the said stationary knife 27 rotates freely the shaft 15, the said stationary knife 27 forming the shearing-edge for the knife 21, the material being forced therebetween by the beveled edge 28 of the knife 20 in its rotary movement.

The front plate,16,is provided with theholes 29, through which the material is forced by the beveled edge on the knife 21. On the outer face of the said front plate,16,rotates the knife 22, which shears the material as it is forced through the holes 29, thus making a final cut at this point, from whence it falls onto the table or projection 32.

The frame9 and the front plate, 16, are held together by meansof the shaft 15, which is extended and provided with the nuts 31 and 50, which serve to lock the entire device together and hold the knives in position, the said front plate, 16, being provided with the projecting pieces 26, which, in addition to holding the stationary knife '27, serve to hold the front plate in position.

The projecting surface 24c on the frame9 is cutaway to the curved form shown in Fig. 4,1n order to permit the material to fall at this point in the path of the knife 20.

The manner of operating is as follows: The device having been secured to a table, either by screws or any of the common clamping de- 7 vices, the material to be chopped is first cut into pieces of suitable size and placed in the hopper 10, from whence it will fall on the proection 24 in the path of the knife 20 and be cut at this point. After this first out the bevel edge 28 on the knife 20 will force the material between the stationary knife 27 and the rotary knife 21,where it will be again out, and by the bevel edge on the rotating knife 21 will be forced through the openings 29 of the front plate, 16, where it will be finally sheared by the rotating knife 22, which rotates closely to the outer face of the front plate, 16, the material dropping onto the table-lips 32in a minced condition. By removing the nut 31 or at either end of the shaft 15 the frame 9 and front plate, 16, may be separated and the knives gotten at for cleaning or sharpening. When the nut 50 is removed, the shaft 15 may be withdrawn from the frame 9, the shaft 15 and the knives remaining fixed in position to the front plate, 16,thus rendering the said knives accessible for cleaning without removing the knives from the shaft. By removing the nut 31 the front plate,16, may be removed and the knives taken from the shaft 15 for the purpose of repairs or sharpening, the shaft 15 remaining fixed to the frame 9. The tapered form of the shaft and the corresponding taper and oblong opening in the knives prevent any wrong adjustment in replacing the knives.

Having described my invention and the manner of operating the same, what I claim, and desire to secure by Letters Patent, is

1. In a meat-cutting machine, the combina tion of the frame 9, the perforated front plate, 16,the fixedknife 27, the disintegrating-knives 20 and 21, each provided with the beveled edge 28, whereby the material is forced through the machine, the rotary shaft 15, provided with the tapered end 19, on which the knives 20 and 21 are placed, and the nuts 31 and 50, arranged one on each end of the shaft 15, whereby the frame 9 and the front plate, 16, are held together, substantially as shown, and for the purpose set forth.

2. In a meat-cutting machine, the combination of the frame 9,the perforated front plate, 16, the disintegratingknives 20 and 21, ar ranged to cut and force the material through the machine, the outside knife, 22, with its cutting-edge rotating close to the outside face of the front plate, 16,whereby the material is again out as it is forced through the perforations in the front plate, 16, the rotary shaft 15, provided with the tapered end 19, on which the

knives

20, 21, and 22 are placed, and the nuts 31 and 50, arranged one on each end of the shaft 15, whereby the frame 9 and the front plate,16,are held together, substantially as shown, and for the purposeset forth.

3. In a meat-cutting machine, the combination of the frame 9, theperforated front plate, 16, the disintegrating-knives, the rotary shaft 15, provided with the tapered end 19,0n which the knives are placed, and the nuts 31 and 50, arranged on either end ofthe shaft 15, by which, on removingthe nut 50, the front plate maybe separated to clean the interior without removing the knives from the shaft, and'by rc= moving the nut 31 the frame 9 and front plate, 16, may be removed and the knives removed from the shaft for the purpose of repairs, &c., for the purpose set forth.

In testimony whereofl affix my signature in presence of two witnesses.

LOUIS FADUM.
