3 claims. (01. 146-217) This invention relates to slicing machines and has more particular reference to slicing machines in which the object carrier is supported in detachable relation to the rest of the mechanism.

Comprehensively stated the invention has reference to a slicing machine in which a portion of the machine is movable relatively to a cutting edge, the movable portion being designed to accommodate different types of object carriers.

More particularly the invention relates to a detachable object carrying attachment which is arranged to feed the object in such a manner as to cut a diagonal slice, and this is achieved in the specific embodiment of the invention shown in igithe drawings, by providing an object-holding device which feeds the object in a vertical direction to an inclined rotating knife, the latter being similar to that shown, for instance, in the prior patent of Peter Sivertsen numbered 1,543,343, and ggidated June 23, 1925.

In order to afford means for using the attachmerit as occasion demands, the object-feeding chute or other attachment is detachably secured to a carriage, which moves past the knife edge, the carriage having adjustable means to fix the object carrier in relation to the knife.

In the drawings which show several embodiments of the invention for the purpose of aifording a clear understanding to those skilled in this gd'jiparticular art:

Fig. 1 shows a side elevation of the invention, showing one object-feeding attachment in place, partly fragmentary and partly in section.

Fig. 2 is a side elevation showing a different 'ifjattachment from that shown in Fig. 1 in place,

partly fragmentary and partly in section;

Fi 3 is a top place view of the attachment shown in Fig. 2, partly fragmentary.

Fig. 4 is a section of Fig. 2 on the lines 44, and Fig. 5 is an end elevation of the attachment. Referring to the drawings and more particularly to the construction shown in Fig. 1, driving mechanism A actuates a rotating knife A, which is in turn located adjacent to the adjustable gage plate B, the latter afiording means to regulate the thickness of the slices to be cut.

A pair of horizontally disposed guide rods C support a reciprocally slidable carriage C, which has an upstanding arm or bracket C terminat- 5 ,ing in a recessed socket D for the purpose of seating a complementary socket member, to which are attached the V-shaped brackets D attached to an object-feeding chute E. The object-feeding chute and adjustable gage and rotating knife are lsimilar to the corresponding elements shown in the Sivertsen patent referred to above and may be inclined from the horizontal as described in that patent. A threaded stud or dowel pin D" projects through a suitable elongated opening in the member D, the elongated opening being for the purpose of affording a vertical adjustment of the feed chute or other attachment, as will be readily understood. The'member to which the bracket D is attached for supporting the feed chute is longitudinally drilled to form an opening at F, to slidably receive a guide bar F and secured by a cross piece G to an object follower or end cutter (not shown) arranged to slide downwardly by its own weight and abut against the end of the object which is to be fed toward the knife edge. The end cutter is more particularly used to facilitate the feed of small objects which do not readily conform themselves to the chute, and to avoid the danger of cutting the fingers when the objects become so small that the fingers may come in contact with the knife.

A normally operable nut H locks the elements D and D together when the nut is screwed on the threaded stud D, as will be readily understood. 3&

Referring more particularly to Figs. 2 to 5, an attachment is shown which feeds the object in a vertical direction to the inclined knife B to effect a diagonal cut of the object when the attachment is moving past the knife edge, and to enable softbodied objects to be fed to a position where they may be cut. The attachment is adapted to be attached to an arm C which forms part of the movable carriage sliding on guide rods, which is the same construction described in connection with the feed chute. Instead of the member D, a bracket K terminates in a bevelled end K which is adapted to be seated in the member D, which is correspondingly bevelled to receive the member K. The member K also has a threaded stud or dowel pin K" which passes through an elongated opening in the member D in the same manner as the pin D" of the chute arrangement. A nut H serves to lock the member K to the member D in the same manner as the members are locked together in the chute arrangement. A stop screw X serves to prevent the pin D" or K" from letting the attachment move toward the knife B, so that the proper clearance between the attachment and the knife may be maintained. The bracket K has formed therewith a vertical plate L which is adapted to cooperate with a vertically disposed plate L which may be corrugated or roughened at L" in the manner shown in Fig. 3. The plate L has a pair of projecting arms M on which the plate L" is supported in slidable relation with the plate L. The plate L normally sliding toward the plate L by its own weight as will be readily understood, and affording a slight pressure against the object adapted to be clamped between the plates L and L, the pressure being insufficient to prevent the object from sliding vertically toward the regulating tray and knife in the same manner as described in connection with the inclined chute arrangements of the Sivertsen patents. horns M may be and preferably is shaped to provide a handle; obviously the handle N is only required at one side of the plate L, the other side of the plate L being merely drilled to receive the horns M.

It is claimed:

1. A slicing machine combining a knife edge, a guide-way, a carriage slidably mounted on the guideway, a feed chute having a stud and means comprising a laterally and upwardly bent arm, one end of which is formed with the carriage and the other end of which has a, recess adapted to receive a corresponding portion of the guide chute and having an opening adapted to receive the stud, the longitudinal axis oi which is perpendicular to the plane of the knife edge to detachably secure the feed chute to the carriage.

2 A slicing machine combining a rotary knife,

The sleeve N sliding on the means for rotating the knife, an upstanding member adapted to be moved back and forth relatively to the knife, a second upstanding member oppositely disposed to the first upstanding member and moving simultaneously therewith, and means for gravity feeding the second upstanding member toward the first named upstanding member whereby a uniform clamping pressure is exerted on the object adapted to be held between the members so that the object may slide downwardly between such members.

3. A slicing machine combining a rotary knife, means for rotating the knife, an upstanding member adapted to be moved back and forth relatively to the knife and having an opening inclined to the horizontal, a second upstanding member oppositely disposed to the first upstanding member, a guide post extending from the second upstanding member and having an inclination corres onding to the inclination of the openand slidably engaging the opening in the upstanding member whereby the second named upstanding member is guided toward the first named upstanding member and normally moves toward itv by its own weight to produce a clamping pressure on the object adapted to be held between the membersso that the object may slide downwardly between such members.
