MEAT-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,131, dated October 29, 1889.

Application filed July 27, 1888. Serial No. 281,191. (No model.)

To a-ZZ 107007721 it may concern:

Be it known that 1, PETER WILKEs, a citizen of the United States, residing at Trenton, New Jersey, have invented new and useful Improvements in Meat-Cutting Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in meat-cutting machines; and it consists, substantially, in such features of arrangement, construction, and combinations of parts as will hereinafter be more particularly described, and pointed out in the claims.

Figure 1 represents a top or plan view of a meat-cutting machine embodying my improvements, and Fig. 2 is a front view thereof. Fig.3 representsa central sectional view of the bowl and its supporting-frame, the same more clearly indicating their peculiar construction. Fig. 4. is a sectional view in detail of the knife-shaft, the dotted lines representing the manner in which said shaft is kerfed or slotted to receive and hold the cut tingblades or knives. Fig. 5 is a sectional detail on the line 00 a: of the hinged lid to more clearly indicate the beveled form of its front edge at this point. Fig. 6 is a view in detail of one of the cutting-blades and its shaft with the shaft in section, the same in dicating the construction of the knife and its mode of fastening or attachment to the shaft. Fig. 7 is a view in detail of'the usual slotted plate through which the knives or cutting blades work. Fig. 8 is a view in detail of the supporting-arm for the shifter-bar that carries the belt-guide.

Reference being had to the several parts by the letters marked thereon, A represents the frame, which is of round or circular contour, and which is provided at suitable points with seats-such as indicated at a--for attachment of the supporting-legs, (not shown,) the said frame and seats being castin one piece. This frame is also cast with an internal flange b entirely around its upper edge, and in which is turned a continuous groove 0 to form a bearing for the bowl, as well as an oil-wel1 or lubricating-chamber in which an oil or lubricant is put to reduce friction between the frame and the said bowl.

B represents a rotatable bowl that is formed with a continuous bearing-flange (Z surrounding its upper edge, the same being turned out exactly true in conformity to the groove 0 of the frame A, in which groove the said flange d is seated and rotates. Either cast with or bolted to this bowl B on the under side is a gear 0, which meshes with a worm e on the shaft D, through which construction and arrangement the said bowl receives its rotation. The shaft D is revolved by suitable belt-connection with the knife-shaft.

E represents the cover for the bowl, the same being hinged to the frame, as at f, and provided with the usual opening in its top for the knives, over which opening is placed the slotted plate g, of common construction. Surrounding the entire edge of this cover is a raised flange h, and extending from the hinges to the forward edge of said cover are two corresponding raised flanges i t', the purpose of all of said flanges being to prevent the oil thrown 01f by the knife-shaft from passing or flowing over into the meat contained in the bowl. At the point at which the meat is first passed or fed into the bowl I give to the edge of the lid or cover an inward slant or bevel, as shown at j, by virtue of which the meat is prevented from being crowded out onto the floor, as happens with machines where this point of the edge of the lid is perfectly straight. To the opposite side of the lid, on its inner or under side, I locate or arrange the plow k on the under side of cover, and which is designed to turn the meat over as the bowl is being rotated. I desire to here state that the use of this plow has been common heretofore, except that its former location has always been on the opposite side or edge of the lid to which I arrange it. I have found that with the former arrangement the meat comes in contact with the back of the plow or shoe instead of the front, and the result is the meat is thrown or forced out of the bowl; but with my present arrangement this does not happen. The lid is formed or provided with suitable bearings F F for the knife-shaft G, each of which is provided with a cap or cup m for containing a lubricating-oil for said shaft, and Z l represent continuous overhanging flanges that are either cast with or bolted fast to the caps m, the said flanges extending over the collars the bowl-cover, from which it may lief-wiped from time to time by the operator.

As a convenient manner of attachment or fastening of the cutting-blades or knives to their shaft, I form in the shaft a number of slots or kerfs corresponding to the number of knives employed, each slot bein g made in the shaft at an angle to the other suclnfor'im stance, as is shown at Fig. 4 in dotted lines.

a This arrangement gives to the knives when inserted the spiral arrangement desirable in this class of machineaea'ch knife projecting from the shaft at a different point of its sides. The knives I-I are'preferablyof"cimeter form, and are formed in theirlower ends with a slot 0 of a width in the proportions of five'-six teenths of an inch less than the diameter of the shaft, such being the proportions of depth of the slots or kerfs. By thisconstru ction'it will be seen that when the knives-are slipped over the shaft in the manner indicated at Fig. 6 one side or edgeof the slots 0 will be received into the ker-f in thefshaft, and the knife thereby securely fastened or attached. This arrangement also permits of tl1esepa rate removal of either of the knives for the purpose of sharpeningor otherwise. Between the knives I arrange on the shaft the collars p, which retain them in place, and for the purpose of tightening up such collars I use'a collar 1", having a thread working on a thread on theshaft, such collar 4* also having holes .9 drilled therein to receive a spanner-wrench for turning the same. j To obviate having to set the machine to the accommodation of any particular direction from which the driving-belt may run or extend -that is to say, whether ,from either side of,beneath, or below the-shaft I employ a square shifter-bar M, that is supported by an arm N, having a squared opening 15, to fit the stud u, on which theloose pulley P-runs, the said arm being held in place by a nut w, the slacking of-which permits the arm to be turned-in either direction to the required extent, and it is by the turning of this arm that the accommodation to the direction of belt is effected. The stud u is held by a bracket to, either cast with or bolted to the side of.

frame'A. v

Carried 011 the inner end of the shifter-bar and adjustable axially by a set-screw x is a belt-guide O, the same having an opening y, through which the beltpasses in an obvious manner and is guided.

P represents a loose pulley working on stud 11. independently of the drive-pulley R,

and is for the purpose of permitting the raising of the lid without being interfered with by the driving-belt.

It should be remarked that the worm D, which operates the bowl, works in a box Z,

cast with or secured to the frame A, the said 1 formed around its upper edge with-a continuous depending bearing-flange and having the hinged lid orcover formed'around its edges with a continuous raised flange and across its top with corresponding flanges, substantially as described.

2. In a meat-cutting machine, the combination, with the supporting frame formed around its upper edge with a continuous flange in which is formed a groove, of the bowl B, formed around its upper edge'with a flange fitting in said'groove. and provided on its under side-with a continuous surrounding worm-gear, "said bowl being also provided with the hinged lid formed atone point of its front edge with the bevel indicated at j, substantially as described. I

3. In a meat-cutting machine, the combi= nation, with the supporting-frame, of the'bowl B, having the hinged lid provided with the raised flanges and the inward slant j, and means for rotating said bowl, substantially as described. v

4. In a meat-cutting machine, the hinged lid or cover formed' 'around its edges with-a continuousraised flange and having two corresponding flanges extending across the same, substantially as shown, and for the purpose described. I

5. In a meat-cutting machine, the hinged lid having the raised flanges and formed at one point of its front edge with an-inward slant or bevel, as indicated at j, substantially asdescribed.

In testimony whereofI have hereuntoset myhand in the presence of two subscribing witnesses.

PETER W'ILKES.
