PANY, A CORPORATION OF INDIANA SLIGING MACHINE Application filed .Tune 25, 1925. Serial No. 39,401.

This invention relates to machines for slicing meats, bread or other commodities, and has for its object the provision of a machine in whichan entire piece may be sliced with- 11. out reclamping and 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 theappended claims.

In the drawings, Fig. 1- is a rear elevation of a slicingmachine having one embodiment of the present invention applied thereto;

\ w'Fig. 2- is an elevation of a supplemental follower member; Fig. 3 is a top plan View of the Inach-ine'shown in Fig. 1; Fig.- 4 is a side elevationof the machine shown in Figures 1 and'3.

1 10 In the embodiment illustrated in the drawings, the numeral10 designates a base frame or" support having ways 11' and -12 which carry areciprocating table 13. The table 13;is reciprocated on its guideways by means of alink 14 pivoted to the table at 15 and connected to a crank arm 16 by a pivot pin 17. The crank arm 16 is screwedto a studshaft 18 journaled in the top of the base 10. A lower end of the shaft 18 carries a beveled gear lawhich meshes with a pinion 20 on a drive shaft 21 journaled in the frame 10. A hand wheel 22 is connected to the end of the shaft-'21 at the operators side of the slicing machine. A shaft 23 is journaled in a sleeve 24 formed'on the frame 10 and the shaft-is provided with a pinion 25 which meshes with the gear 19. i

The shaft 23-carries' a sprocket wheel 26 having a chain 27 extending upwardly therefrom and enclosed in-a chain box 28, which also forms a support for a disk knife 29. Knife 29 is mounted on a stud shaft 30 at the upper end of the chain box 28 and is driven by a sprocket wheel 31 over which the chain 27 passes; It may be noted that the axis of'the knife 29' is arranged'adjacent the operators position and'is spaced away from the opposite side of'the machine a sufl'icientdistance'to permit the reciprocating table to move away 50 from the operator" past the slicing knife.

' ator.

This permits the slices to be severed during the movement of the table toward the oper- Heretoforemachines of this nature have been arranged to sever the slices during the movement of the table away from the" operator. I i

The present arrangement has the advantage that it facilitates receiving the slicesas they are formed and arranging them by hand stack upon the slice receiving in an orderly plate. It also permits the edge of the knife toward the operator to be enclosed in a guard shown at 32. The arrangement is also better adapted to the form of holding mechanism employed in the present invention than is the arrangement heretofore employed, in which the slices are severed during the movement away from the operator.

The'reciprocating table is preferably pr-ovlded with corrugations .33 extending transversely to the direction of reciprocation of the table and the material to be sliced is' placed 'uponthese corrugations and is fed forwardly longitudinally of the corrugations. An upright abutment 34 is provided at the edge of the table away from the operator and forms a stop against which the piece to be sliced is placed.

A follower plate 35 is mounted. to slide in dovetail grooves 36 formed at the opposite sides of the reciprocatingtable 13. A follower block 36 is screwed to the plate 35 and engages the rear face of the piece to be sliced. The plate 35 is provided with an arm 37 having a half nut 38 at its outer end arranged to mesh with a feed screw 39.

The feed screw 39 is rotated by a rachet mechanism 40 'Which may be of usual construction and which advances the follower plate 35 by predetermined amounts at the end of each reciprov cation of the table 13.

The follower block 36 is provided with a longitudinal groove 41 in which a bolt having a square shank 42 is arranged to slide. The bolt 42 carries a clamping bar 43 at its forward end which may be located in adjusted positions along the block 36 by means of a wing nut 44. The bar 43' is provided with teeth 45 for engaging the edge of the piece to be'clamped at the corner thereof remote supporting from the abutment 34 and from the cutting plane of the slicing knife.

A plate 46, having corrugations 47 on the lower face thereof, is arranged to rest upon the top surface of the piece to be sliced. This plate is mounted on posts 47 arranged at the two corners of the table adjacent the operators position and on the abutment plate 34 at the opposite side of the reciprocating table.

Spring pressed pins 48 are carried by lugs 49 on the top of the plate 46 and extend into grooves 50 in the post 47 and plate 34. The pins 48 may be arranged to move freely in the grooves 50, or sufficient friction may be produced by the spring pressure of the pins .48 in their respective grooves toretain the plate 46 in various positions of vertical adj ustment.

During a slicing operation, the piece is held against the force of the knife 29 by the ,7 table 13 and the abutment plate 34. The corrugations 33 and 47 cooperating with the teeth 45 overcome any tendency of the piece to be rotated about a vertical axis, due to the force of the knife upon the piece.

The follower 36 feeds the piece forwardly step by step between the corrugations on the table 13 and the plate 46. The follower 36 is sufficiently low to permitthe plate 46 to rest on the top of the thinnest pieces sliced in the machine.

Supplemental follower blocks 51, shown in Fig. 2, are arranged to be detachably supported on the upper face of the block 36, (see Fig. 4) so as to assist in holding the rear side of pieces having a greater thickness than the height of the single block 36. The supplemental block 51 is provided witlf pins 52 for holding it in place on the block 36. The clamping bar 53 is also adjustably mounted on block 51 in a manner similar to the bar 43 on the block 36.
