Original application filed July 2, 1918, Serial No. 243,022. Divided and this application filed August 25,

To all whom it may concern:

Be it known that I, EDWARD M. S'rILns, a

citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in Workholders for Slicing Machines, of which the following is a specification.

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 Fig. 1 is a rear elevation of one form of work-holder embodying thepresent invention.

Fig. 2 is a top plan view partly in section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary vertical section on the line 3-3 of Fig. 1. y

This application is a division of application Serial No. 243,022, filed July 2, 1918, patented December 20, 1921, No. 1,400,698.

In 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 sliced is placed on the plate 11 and held during-the slicing operation by a clamp or holder of the same form. It is usual to provide the edge of the talole 10 which passesadjacent 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. After a pieceof material has been almost completely sliced 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 pres ent invention provides means for engaging the face of the 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 the plate while at the same time the rear surface is also grasped and held inposition. Whenmeat" forwardly from the holder is held against lateral pressure of the slicing knife by the corrugations in the plate on which it rests.

In the form of the invention shown in i I i this application the material is forced clownwardly into engagement with the corrugated plate 12 by pivotal movement of engaging teeth'supported on the holder in a manner The plate 33 is provided with a plurality of slots 34 having lugs 35 extending rearwardly from the edges thereof andpins or teeth 36 supported on pivots 37 between the lugs 35. Each pin 36 is provided with a rearwardly projecting bifurcated portion 38 which engages a pin 39 carried 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 whichhave their ends guided in slots formed on the inner faces of the upright frame members 15. A pair of links 43 is pivoted to lugs44 connected with the cross bar 41, and the upper ends of the links 43 are connected with the prongs 45 of an operating lever 46 by pivot pins 47. The lever 46 is fulcrumed at 48 on lugs 49 carried by the upper cross bar 16 of the holder frame. A handle 50 may be attached to the bar 16 for lifting the holder. The lever 46 and lugs 49 are provided with shoulde'rs5l and 52 for limiting the downward movement of the lever 46. In operation the lever 46 is pins 36 extend horizontally. The meat to be sliced is then placed upon the uppersurfacc of the corrugated plate 12 and prongs 36 are caused to penetrate the meat sufficiently to permit the rear face of the meat to engage the front face of the plate 33. 46 is then swung downwardly into the position shown in broken lines in Fig. 3, which movement tilts the prongs 36 downwardly, as indicated in that figure, and thus draws the meat tightly into engagement with the front face of the plate 33 and at the same held in its UPPBI'IIIOSl] position sothat the The lever time torces it firmly into contact with the upper corrugated surface of the plate 12. The lever 46 and links 43 are preferably so related to one another that the lever will passdead centerjust'betore it reaches the limit of its downward movemenhand'in this way the pins are locked in their downward position.

Iclalm:

1. A wort: holder for slicing machines comprising an upr'ght frame having an abutment plate thereon, a plurality of teeth pivotally mounted on said frame and ariaiured to project forwardly from-said plate when in suitable position to receive material to be sliced as it IS moved against said plate, and rneans't'or shitting said teeth upon their pivots in a directionsubstantially normal to the-longitudinal axis of said plus to cause them to clamp said mater a]- against said plate. I

.2. A. work-holder for slicing machines, comprising anupright plate, a plurality oi substantially straight pins projecting torwardly from said plate and pivotally mounted thereon, and means for shitting said pins about their pivots to cause them -to clamp material against said plate.

lna slicing machine, a work-supporting table, a work-holder mounted on said table and having an upright plate, Ia plurality of ivotallyi mounted pins projecting forwardly from said plate inpos tion to enter material as itis moved against said plate, and means. for moving the forwart ends or said pins downwardly about their pivots and transversely of their lengthto cause them to press material against'the upper face of said work-supporting table and to clamp sa d material against said plate.

i A work-holder tor shcmg machines,

' comprising a frame having stationary pivots thereon, work-engaging pins each separately mounted on one of said pivots, and a secondary frame movably mounted on said first mentioned frame and ene ing said pins to shift said pins upon their pivots and comprising a support for material to be tion sliced, a frame arranged in an upright posiabove said support, substant'iall straight pins pivotally mounted on said trains and movable into position to extend substantially horizontally therefrom, and mechanism for tilting said pins downwardly into an inclined position to cause said pins to depress material engaged thereby against said work-support and against the face of said upright frame.

7. The combination with a work-support for slicing machines, .ofa Work-holder having an upright bearing surface arranged above said support, worl -engaging pins plvotally mounted on said holder and projecting trom the work-engaging face thereof sul'istantialjly :normal thereto when in work-receiving position, means for swinging said pins downwardly about thelr pivotal support on said Work-holder trom a substantially horizontal to an inclined position, and means for locking said pins in saidinclined position.

S. A meat end grip .l or slicing machines comprising a support ng frame ha *ing an upright abutment plate, tines supported by said frame and projecting at all times through openings in said plate to engage material to be held, andia-tine actuating frame member movable relative to said supporting frame-and engaging said tines to cause them to grip material and hold it against said abutment plate. 7

9. A. meat end grip for slicing machines comprising a supporting frame having an upright abutment plate thereon, pointed tines movably mounted on fixed supports and projecting at all times through slotsin said abutment platc,,a tine actuating frame arranged-in the rear of saidabutment plate and movable relative thereto substantially abutment member and enga ing said tines to move said tines in said openings, and means toi actuatingsaid frame.

Intestimony whereof I have signed my name to this specification on this 21st day of August, AuD. 1919.
