MEAT CUTTING AND MIXING MACHINE.

SPECIFICATION forming part of Letters Patent No. 359,837, dated March 22, 1887.

Application iiled August 21, 1856. Serial No. 211,474. (No model.)

, drawings, is a specification.

This invention is in the nature of an improvement upon the apparatus set forth in my various meat-cutter patents, dated February 27 and October 23, 1883, and August 19, 1884.

The invention consists in the novel construc tion and combination of parts, hereinafter pointed out and claimed, by which the ma chine is made more strong and durable and more certain and effective in operation.

In the drawings, Figure 1 is a side elevation of my improved machine with the cylinder turned down horizontally for removal of the cutting or mixing mechanism. Fig. 2 is a vertical central section with the cylinder turned up into working position and the cutters and discharging head removed. Figs. 3 and 4 are details in plan and vertical section of the discharging-head detached. Fig. 5 represents the feed-screw and its shaft which receives the revolving cutters or mixingfingers. Fig.6 isa detail of the receivingmouth of the machine, and Fig. 7 represents the strainenplate and radial clearing-knife enlarged. Fig. 8 is a transverse section of the cylinder; and Fig. 9 alower end view thereof, the head being removed.

In my patent of August 19, 1884, the cutting apparatus and internal character of the cylinder with its recesses to receive the stationary cutters are clearly set forth. I follow the general construction therein shown in connection with my present improvements, referring to said patent for details not herein de scribed.

A is the base of the machine, of suitable form and dimensions to support the 'mechanism at a convenient height.

B is the cylinder, connected to the base by trunnions or pivot-bolts O, which enter or form at a convenient point without distorting the cylinder proper. The pivots C are so located that the cylinder and parts mounted thereon are nearly balanced, so as to make the tipping down or turning up of the same simple and easy.

A suitable shoulder or stop, E, is provided on the base, on which the tipped-down cylinder may rest, and a bolt, F, or equivalent fastening,secures them together in working position. In this instance the base is recessed to receive an arm projecting from the shell D, and the bolt F passes through both. (See Fig. 2.)

The tipping down of the cylinder into a horizontal or nearly horizontal position is a great convenience in removing the feed-screw and cutting apparatus for grinding and cleaning from time to time, since all the cutters, both fixed and rotary, meshing with each other must be removed and inserted together, and this is accomplished with far greater ease in a horizontal position than when placed vertically or obliquely.

In substituting the mixing for the cutting apparatus, as well as in cleaning the machine, the pivoting of the cylinder is of great advantage.

Within the cylinder B are recesses G and H to receive the blocks of stationary knives and the clearing-knife, as described in my former patent. In addition to these, I now still further recess the lower end of the cylinder, as at I, Fig. 2, to afford increased space for the perforated strainer-plate J and the radiating clearing-knife K of Fig. 7, as compared with that given to the cutters above said parts. Thus any tendency to clog the strainer-plate by the feed-screw and cutters presenting the out meat to it too rapidly is avoided, and the action of the machine is greatly improved. Fig. 7 represents the enlarged strainer-plate. which revolves in the recess I of Fig. 2, and illustrates the new form which I now give to the clcaringknife K, cooperating with said plate and held stationary by the recesses H. By my present improvement the cutting-edges Z of said knife, which lie in close contact with either or both surfaces of the perforated plate J, extend along a line drawn radially from the axis of the rotating shaft L, or nearly so, to

the circumference of such plate. This constrnction avoids atendency to crowd the meat outwardly away from the shaft, and thus reduces the leverage and makes the cutting action direct and positive.

The recesses H are only at the lower end of the cylinder, where they receive the shanks of the knife K and hold it while the perforated plate J is revolved by the shaft. The recesses G run up the inside of the cylinder to the spir'al grooves and hold the blocks of stationary cutters which cooperate with the rotary series carried by the shaft.

To further facilitate clearance of the cut -meat, I cut away oneside of the dischargingfor supporting the cntt-ers fixed on said shaft,

longitudinal adjustment of which, to a nicety, is effected by the axial supporting-screw O with its check-nut P.

Between the foot of the shaft L and the tip of its supporting-screw O, 1 introduce, in the socket N, a disk, Q, of dried rawhide, which is exceedingly tough and wear-resisting and has no tendency to corrode or to injuriously affect the material treated in the machine. Its use is, for these reasons, of material advantage.

The head M, with parts supported thereby, is upheld in position by pivoted hooks 1%,. Fig.1, as in my formcr patent. In practical: use this head sometimes becomes so stuck or fixed in its position that it will .not drop away on releasing said hooks. I therefore provide, at some convenient point between the head and cylinder end, a tapering recess in which to introduce a wedge or cold-chisel, so that a blow thereon will readily loosen the head. Sueha recess is indicated at S, Figs. 1 and 4:.

Figs. 2 and 6 illustrate a feature of my improvements designed to facilitate introducing the meatthrongh the hopper T into the cylinder. This improvement consists ina beveled surface, U, formed on the cylinder 13 within the hopperavalls, or a sloping side of the hopper, as at U, so that the meat willonly enter in advance of the flange of the feedscrew in its rotation, and thus will not be packed in the hopper and retarded in entering. The bevel-surface U is made to correspond substantially in its inclination with that of the flange V, and it is found in prac tice that by thus carrying the mouth of the hopper to the left or beveling it about as shown the reception of the meat from the hopper is improved.

This mechanism is adapted equally for the cutting of meats and for mixing the seasoning materials with the meat by simply substituting for the cutting apparatus blunt pins or fingers projecting from the rotary shaft and corresponding stationary prongs within the cylinder. This maybe done by introducing a duplicate shaft with fingers and sets of stationary pins suitable for stirring and mixing. in place of the cutter-shaft and the fixed and rotary cutters; or, cutter-shaft Lanay be perforated, as indicated at V, Fig. 5, and, afteri removing the cutters carried by it, pins may be inserted in the holes \V, and thus the same shaft serve for both purposes in the machine.

I claim as my invention 1. The base A and cylinder 13, said cylinder having operating mechanism substantially as described, combined with the shell D, bolted to the cylinder and pivoted to the-base, substantially as described.

2. The combination withthe cylinder 13, having independent internal recesses for the stationary knives andfor the clearing-knives and for the strainer-plate, of the clearingknives having their edges proximate to the face of the plate, and the revolvingperforated plate secured to the rotary axis and resting in its recess in the cylinder, as set forth.

3. The cylinder B and hopperT, formed with the beveled surface U within the hopper adjoining the opening into the cylinder, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification,in the presence of two subscribing witnesses, on this 16th day of August, A. D. 1886.
