SLICING PATENT CORPORATION OF INDIANA MACHINE Application filed October 16, 1926. Serial No. 141,901.

This invention relates to machines "for slicing'meat and other commodities'and has for its object the provision of a slice receiver for slicing machines of the type, in which the material is fed toward the slicing knife relative to a support which is reciprocated in the direction of thecut'ting plane of the knife;

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 par ticularly pointed out in the appended claims.

In the drawings Fig. 1 is an elevation of one form of slicing machine having an embodiment of the present invention applied thereto;

Fig. 2 is an end elevation of the machine shown in Fig. 1 with parts in section;

Fig. 3 is a view looking in the direction of the arrow 3 in Fig. 2; p w

beneath the knife. A housing plate 25 encloses the lower side of the slicing knife and its supporting mechanism together with the lower portion of the belt groove 21 and the belt running therein. The housing plate 25 is conical in shape and its outer periphery lies adjacent the edge of the slicing knife and forms a deflector for deflecting the slices away from theslicing knifeas they are severed. The front edge of the knife or the edge at the left in Figs. 1 and 3, is exposed but the upper and rear portions ofthe edge are covered by a guard plate 26 which has an exten- Sion 27 forming a housing for the belt 22 and pulley wheel 23.

'A second bracket 28, similar in shape to the bracket 13, is mounted on the base at the end ofthe base opposite the bracket 13 and carries a stop or abutmentplate 29 for guidv .ing the meat toward the exposed edge of the knife and for regulating the thickness of Fig. 5 is an elevation of the supporting the slices. The plate 29 is pivotally mounted bracket for the abutment table viewed from the left in Fig. 1

Fig. 6 is a section on line 6-6 of Fig. 2;

Fig. 7 is a section on line 7-7 ofFig. 2.

The machine, as illustrated, is provided with a supporting base 10 having blocks 11 at opposite ends thereof to which guide 'rods 12 are secured. A bracket .13 is mounted on the base 10 at the side opposite the guiderods 12 and is provided with a stud shaft 14 on which a slicing knife 15 is journaled to .rotate. A bushing 16 is interposed between the knife 15 and stud shaft 1 1 and the bushing is held in place on the stud shaft by a disc 17 which is secured to the shaft 14 by a screw 18.

A cover plate 19 is fastened to the outer face of the disc 17 and the periphery of the cover plate fits into a notch near the outer edge of the knife 15. The knife 15 may be-ma-de in the form of a ring having a supporting spider 20 which is provided with a belt groove 21 for receiving a. belt 22. The belt 22 passes over a pulley 23 secured to the shaft of a motor 24 which is mounted on the bracket 13'. It should be noted that the bracket 13 is of a goose-neck shape to leave an open space beneath the slicing knife for allowing the slice receiver 48' (described later) to reciprocate on a spindle 'carried by lugs 31 on the bracket 28. The side of the plate adjacent the knife 15 is shaped toconform to'the contour of the periphery of the knife and may be swung about the spindle 30 in a direc-. tion transverse to the cutting plane of the knife. The position of the plate 29 isregu- ,lated. by cams 32 secured to a shaft 33 journaled in lugs 34 on the bracket'28. A hand crank 35 is secured to the end of the shaft for rotating the cams 32 toward and away from the cutting plane of the knife to regulate the thickness of slices. An'indeiz plate 36 is mounted on the bracket 28 adjacent the crank; 35 for indicating the thickness of slices for the different positions of the hand crank.

The material to be sliced is supported in a trough 37 inclined at. approximately to the horizontal and normal to the cutting plane of the knife 15. The trough 37 is carried by brackets 38 which project upwardly from a carriage 39 slidably mounted on the guide rods The carriage 39 is provided with a handle 40 by means of which it may be moved by hand along the guides 12.

This will reciprocate the work held in the trough 37 over the plate 19 toward and from the cutting edge of the slicing knife to sever slices from the lower face of the material in the trough 37.

The brackets 38 are provided with guide sleeves 41 in which a rod 42 is 'slidably mounted, the rod being inclined at the same angle as the trough 37. A finger 43 is secured to the rod 42 and extends upwardly therefrom through a slot 44 in the bottom of the trough 37. The finger 43 carries sharpened pins 45 which project into the trough 87 and penetrate the material supported in the trough. The upper end of the rod 42 is provided with a knob 46 which may be grasped by the operator to feed the material downwardly in the trough after each slice is severed to present a new portion to be sliced. The carriage 39 carries a bracket 47 which projects beneath the knife 15 and supports a slice receiving trough 48 which will be re ciprocated by the carriage 39 in unison with the movement of the trough 37. v The contact faces'of the side walls of the troughs 37 and 48 are preferablycorrugated, as clearly shown in Figs. 3 and 6, to reduce the friction of a stack of slices as it moves downwardly in the trough. The slices are supported in the trough 48 by a plate 49 carried on a finger 50 secured to the end of the rod 42 and projecting upwardly through a slot 51 in the bottom of the trough 48. The plate 49 is preferably shaped to fit the inside of the trough 48, as shown in Fig. 6. Since the trough 48 and finger 50 are both constrained to move with the carriage 39, they will be'in position tp receive theslice as it is severed from the. piece in the trough 37 and projected beneath the cutting edge of the knife 15. It will be obvious that ordinarily the angle at which the trough 37 is set is great enough so that the material to be sliced will be carried downwardly by gravity along the trough after each slice is cut so as ,to be in a position to have the next slice cut therefrom, and the pins 45. d no to their engagement with the material, will move the rod 42 and consequently the finger 50 a corresponding amount to make room for the next slice which is to be cut from the material. angle 18 not great enough to cause the work to be fed by gravity, the knob 36 may be used I as previously explained to move the work, as

well as the slice receiver, manually.

In operation, the handle 46 will be drawn upwardly when a piece is to be sliced and the piece will be placed in the trough 37 with 'the tines 45penetrating the piece. lhe motor will be driven to rotate the knife 15 and the handle 40 will be moved back and forth to reciprocate the carriage 39 on the guides 12. As a slice is severed, it will be deflected by the guard 25 away from the slicing knife into the trough 48 and against the plate 49. Since the slice receiver moves in unison with the slice as it is projected fromthe slicing However, if the knife, it is apparent that the slice will be spread against the face of the plate 49 and will be held in an inclined position on the trough 48. As the piece is fed downwardly in the trough 37, either by gravity or by the handle 46, the plate 49 will be moved downwardly corresponding amounts to accommodate additional slices as they are formed. The advantage of having the knife inclined as shown is so that the slices are out from the material in a plane substantially paralled to that in which the slice rests after it has been severed from the material. This prevents the slice from curling and facilitates stacking without special devices toinsure efficient stacking. In this way, the slices will be arranged in an orderly stack in readiness to be wrapped and delivered to the customer. It will be apparent that the Slices may be readi] y reached to be removed from the receiving trough 48 either from the end of the support 10 or from between the brackets 13 and 28. The supporting plate 49 may be dropped downwardly to facilitate removal of the slices, if desired, but this will not be found necessary in most cases.

The shape of the brackets 13 and 28 is such that the motor is supported at a point removed from the position at which the slices are delivered and the support for the knife v is also ofi'set relative to the axis of the knife, leaving clear space.at the side of the knife for the slice receiver.
