Claims. (Cl. 146-114) The present invention relates to vegetable slicing and shredding devices and more particularly to the type having cutting edges on a rotatable wheel frame and means to adjust the thickness of slice.

The principal object of this invention is to provide a novel and improved cutting wheel for effecting a plulurality of slices per revolution thereof and affording but a single means requiring a simple adjustment to alter slice thickness.

Another object hereof is to provide a rotatable cut ting wheel of the character mentioned of novel and improved construction, having a cutting member which presents a plurality of cutting edges only half of which are in use at any one time. When the cut-ting edges in use become dull, the cutting member may be reset on the wheel member so that the other cutting edges thereof are in operating position.

A further object of this invention is to provide a novel and improved cutting wheel of the kind described, having an adjustable slice gage member for each active cutting edge; all of said gage members being associated to be given identical movement without the use of any spring means, but utilizing but a single screw to accomplish their simultaneous adjustment for change in slice thickness.

Another object of this invention is to provide a novel and improved cutting wheel for cutting a plurality of slices per revolution thereof, which is a unitary structure including cutting means, slice-gage means for each cutting edge and a single thickness-of-slice adjustment heretofore in use, and may be substituted therefor by being mounted on the drive shaft of existing devices of this class where dimensions suit.

A further object hereof is to provide a novel and improved cutting wheel unit of the nature set forth, which is reasonably cheap to manufacture, easy to use and adjust, and efficient in carrying out the purposes for which it is designed.

Other objects and advantages will become apparent as this disclosure proceeds.

Fig. 10 is the front view of a blade member for a cutting wheel in accordance with this invention for effecting four slices per revolution. The device shown in Fig. l, is for cutting two slices per revolution.

In the preferred embodiment, the ,device illustrated in the drawings is for cutting two slices of vegetable 15 per revolution of the cutting wheel denoted generally by the numeral 16. Hence two radial cutting edges 17,17 are provided, each associated with a gage plate. These cutting edges may be on a single member 19. The gage plates indicated by the numerals 18 and 18 respectively are swingably mounted means. The member 19 is of a shape comprising substantially two opposite circle sectors. Each of the gage plates or vanes fit substantially as one of the remaining sectors of such circle. The member 19 and the gage plates are mounted on a ring 24 across one end thereof. Means to adjust the gage plates, is positioned within such ring which may be the rim of a wheel structure, here made up of the wheel parts 20 and 21. The gage adjustment means indicated generally as 29 includes a journalled screw 22 carrying in threaded engagement thereon the nut structure 23. I

The rims 24 and 25 of the respective Wheel parts, fit telescopically and so assembled, are secured to each other in any suitable manner. The wheel part 21 has a hub 26 and few spokes. 27. It is by this hub that the cutting wheel 16 may be mounted on a drive shaft 28 which is journalledon the frame 50 in bearing 51. As a convenient mount for the screw 22 of the gage adjustment means 29, the wheel part 20 may also have a short hub 30 in which said screw is journalled. The head of said screw is against the front face of the hub 30 and lies within a clearance hole through the blade member; such hole being 31. Of course, the hubs 26 and 30 are spaced so that the threaded shank of the screw 22 may be of sufficient length to permit a predetermined scope of movement of said nut structure 23 along said screw.

The exposed surface of the wheel part 20 shown in Fig. 4, is flat and no part of the device projects in front of the exposed face of the blade member 19, save the head of the screw 22 slightly. Said member 19 is mounted on the wheel structure by means of the screws 32. The cutting edges 17 and 17' are so positioned here, that upon rotation of the cutting .wheel 16 counter-clockwise in Fig. 1, said edges will cut the vegetable 15 held tothe left of the center of the said cutting wheel and against the face of said cutting wheel, in the hopper 33. Although the edges 34 and 34' of the member 19 do no cutting in the set up illustrated, they may also be sharpened in such manner that they will cut when the member 19 is removed and reset after being turned so that its surfaces are reversed. The spokes 35 of the wheel part 20 are so positioned with respect to the rim 24, that they act to support the blade member 19 along the edges doing no cutting. The free area of each sector of the blade member and the area of each gage plate, is large enough to include the face area of the largest slice of the vegetable 15. The space or openings between the spokes 27 should be large enough to permit slices cut to fall down out of the wheel structure.

The gage plate 151 has an edge 118 parallel and adjacent the cutting edge 17, and is mounted to swing on the axis pin 36 carrying the bent ears 137 of said gage plate. Likewise, the gage plate 18' has an edge 118' parallel and adjacent the cutting edge 17', and is mounted to swing on the axis pin 36' carrying the bent ears 138 of the gage plate 18. Preferably, each such axis pin is parallel respectively to the cutting edge of the member 19 related to the gage plate carried on such pin. These mentioned axis pins are mounted near the periphery of the wheel structure. Each of the gage plates has a tab or ear extending away from the head of the screw 22 and spaced from its axis of swing. Such tabs are denoted respectively by the numerals 37 and 37, and each has a hole indicated respectively as 38 and 38 for slidably receiving therethrough a pin extending radially from the nut 39. These radial pins 40, 40', are positioned in such holes. It is evident that upon turning the journalled screw 22, an adjustment easily made by screw driver at the front of the cutting wheel 16, the nut 39 will ride therealong and the front face of each gage plate will make an identical angle with the plane of the blade member 19. Also, the gage plates 18, 18' being identical, the distance between edges 17, 118, and 17', and 118' will be equal always. The holes 38, 38' are of equal size, and the pins 40, 40 are of equal diameter and of such size smaller than said holes they are through, to permit gage plate swing movement.

To operate, the screw 22 is first adjusted to set the distance"A to the slice thickness desired. A vegetable within the hopper 33 is constantly pushed by, for instance, the slidably mounted pusher rod 42 against the face of the cutting wheel 16, while said wheel is rotated counterclockwise by the turning of the shaft 28.

When the cutting edges 17, 17' become dull, the member 19 is removed and reset with its surfaces reversed so that the cutting edges 34, 34 shall do the cutting; the screws 32 being on a diameter of the cutting wheel which is the center line of symmetry of the blade member 19. The clearance hole 31 permits blade removal.

As the slice being cut travels along the back side of the blade cutting it, such slice will be bent slightly by the rounded edge of the spoke and the slice will separate and quit adherence to the blade member 19 and fall off when the full slice is severed. If such slice is very small and does adhere to the back side of the blade member, it will he slid off by the next slice when it is being cut.

A cutting wheel for more than two slices per revolution inaccordance with this invention, is shown in Fig. 10 where a blade member 44 is outlined having four cutting edges 44'. There would, of course, be one gage plate like 18 for each of such cutting edges and each gage plate would be associated with one pin like 40 on the nut structure 23 which would have four radial pins, as is well understood without the necessity of further illustration.

This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiment shown herein be deemed illustrative and not restrictive and that the patent shall cover all patentable novelty herein set forth; reference being had to the following claims rather than to the specific description herein to indicate the scope of this invention.

We claim 1. In a food slicing device of the character described,
