Application filed July 2, 1918.

To all whom it may concern:

Be it known that l, EDWARD M. S'rmns, a citizen of the United States, residing at Mount Pleasant, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Holders for Slicing-Machines, of which the following is a specification. a

The object of this invention is to provide a device of the class named which shall be of improved construction and operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification, and it is more particularly pointed out in the appended claims.

In the drawings- Figure 1 is a rear elevation of a work holder for a slicing machine embodying one form of the present invention. I

Fig. 2 is a vertical sectional view on line 2-2 of Fig. 1. p

Fig. 3 isa View similar to Fig. 1 showing a modification.

Fig. 4 is'a vertical section on line 4.- l of Fig. 3; and r Fig. 5 is a fragmentary top plan of the holder shown in Fig. 3 with parts in section along line 5-5 of that figure.

Tn slicing machines of the usual form, there is provided a reciprocating table shown at 10 in the drawings, upon which a sliding work holder or meat plate 11 is mounted. The material to be 5 sliced is placed on the plate 11 and held during the slicing operation by a clamp or holder of some form. It is usual to provide the edge of the table 10 which passes adjacent the slicing knife during the slicing operation with a corrugated plate 12 which supports the portion of the meat, or other material being sliced projecting toward the slicing knife. almost completely sliced, as shown at 14 in Fig. 2, it is impossible to longer clamp the material upon the meat plate 11 by a clamp which bears upon the upper face of the material, and the present invention provides means for engaging the face ofQthe material opposite that from which the slices are being cut for the purpose of forcing the material downwardly upon the plate 12 so that its bottom surface may" be firmly held against this plate, while at the sametime Specification of Letters Patent.

After a pieceof material has been Patented Dec. 20, 1921..

Serial No. 243,022.

the rear surface is also grasped and held in position. The holder includes a frame having vertical side bars 15 and an upper crossbar 16, the frame being held in position upon the meat plate 11 by hooks 17 and 18 arranged to engage uprights 19 and 20, respectively. The uprights 19 and 20 are carried by the guide bars 21 which form the sides of the support 11 and which slide upon the upper surface of the table 10. Thespace within the holder frame formed by the bars 15 and 16 is filled by an upright plate 22 having lugs 23 projecting from its rear face, the lugs being provided with inclined slots 24 which engage pins 25 extending inwardly from the inner faces of the bars 15. A pair of bearing lugs '26 is alsosecured to the rear face of the plate 22 to which lugs are pivoted links 27 having their opposite ends pivotallyconnected to a rod 28 journaled at its center in an opening passing through an operating handle 29. The handle 29 is fulcrumed upon a pin 30 connected to the upper crossbar 16 by hearing brackets 31. On the front face of the plate 22iis a plurality of forwardly and downwardly inclined prongs or teeth 32 which engagethe meat or. other material to be sliced and hold it in place.

In operating the holder, the meat or other,

with the otherhand, thus forcingtheplate 22 with its teeth forwardly and downwardly guided, by the slots 24: and pins 25. This causes the teeth 32 to enter the rear face of the meat, and at the same time crowds the meat firmly against the supporting surface'of the plate 12. The downward inclination ofthe teeth 32 prevents any upward, forward or lateral movement of the meat duringtheslicing operation, and the plate 12 supports the meat against downward movement. Atthe same time the corrugations in the [upper surface of the plate 12 prevent lateral movement of the portion of the meat projectingin front of the holder toward the slicing knife. It is of great advantage to have the meat firmly held against these corrugations rather than supported entirely by the plate 12, for the reason that the portion of the meat projecting forwardly from the holder is'held against the lateral pressure of the slicing knife by the corrugations in the plate upon which it rests. V

' Inthe modified form shown in Figs. 3, 4 and 5, the material is forced downwardly into engagement with the corrugated plate.

' 12 by a pivotal movement of the teeth instead ofa movement of the plateon which the teeth are supported. In this form a front plate 33 is rigidly secured to the frame bars and 16, and this plate is provided V with a plurality of slots 34 having lugs 35 extending rearwardly from the edges thereof, and pins or teeth 36 supported on pivots 37 between the lugs. Each pin 36 is provided with a rearwardly projecting bifurcated. portion 38 which engages a pin 39 car- 7 ried between spaced upright bars 40 arranged to move vertically in the rear of the plate 33. The bars 40 are all connected by cross-bars 41 and 42 which have their ends guided in slots formedon the inner faces of the upright frame members 15. A pair of links 43 is pivoted to lugs 44 connected I with the cross-bar 41, and they upper ends of the links 43 are connected with the prongs 45' of an operating lever 46 by pivot pins 47. The lever 46is fulcrumed at 48 on lugs 49 carried by the upper cross bar 16 of the holder frame. A handle 50 may be attached tothe barxl6 for lifting the holder; The

lever 46' and'flugs 49 are provided with shoulders 51 and 52 for limiting the clownward movement of the'lever 46. In operation the lever 46 isheld in its upper 13081 tion so that the'rpins 36 extend horizontally. The meat to be sliced is then placed upon the upper surface of the corrugated plate 12 and forced toward the holder until the prongs 36' penetrate the meat sufliciently to aermit the rear faceof the meat to. engage the; front face of the plate 33. The lever 46 is thenswung downwardly in the position shown in broken lines in Fig. 4, which movement tiltsithe prongs 36 downwardly,

as indicated intliatfigure, and thus draws the meat. tightly into engagement with the front face of the plate 33, and at the same time forces it firmly into contactwith the upper corrugated surface of the plate12.v The-lever 46 and links 43 are preferably so related to one another that the lever will' pass dead center just before it reaches the limit of its downwardmov'ement, and in this waythe pins are locked in their downward position. A similar or other locking arrangement may be provided' for the form shown in Figs. 1 and 2, if desired.
