VEGETABLE-CUTTER.

Application filed April 26, 1921.

To all whom it may concern Be it known that we, HARRY A. STODDA'RD and FRANCIS E. CALLAHAN, citizens of the United States of America, residing at C0- lumbus, in thecounty of Franklin and State of ()hio, have invented certain new and useful Improvements in Vegetable-Cutters, of which the following is aspecification.

Our present invention relates generally to vegetable cutters and more particularly to slicing machines, our object being the provision of a simple inexpensive arrangement involving but few parts and capable of be ing maintained in a highly sanitary condition at all times, by which vegetables, fruits and the like particularly potatoes and apples may be sliced evenly and uniformly down to the last bit, without danger to the operator and in fact mechanically without the presence of an operator.

With these objects in mind our invention proposes a slicing machine of the type and construction shown in the accompanying drawing, which forms a part of this specifieation, and wherein,

Figure 1 is a front proved machine,

Fig. 2 is a side View,

Fig. 3 is a front view with the cutter removed,

Fig. f is an enlarged vertical section taken centrally through the lower portion of the machine, V

Fig. 5 is a horizontal section taken on an enlarged scale and substantially on line 5-5 of Fig. 3, and

I Fig. 6 is a top plan view partly broken away and in section of the cutter wheel.

Referring now to these figures our invention proposes a machine which includes a hopper 10 adapted to contain vegetables, fruit and the like to be sliced, and open at its top for the reception of such articles although it will be understood from the matelevation of our imter to follow that the feed of articles to the from the hopper 10 and the opposite end of which leads to the front of the machine and communicates with one end 12 of a Specification of Letters Patent.

spirally curved discharge slot 13 in a circular faceplate 1 1 with which the hopper is provided at its lower front portion.

The hopper 10 may be supported in any suitable manner as by means of legs 15 and its face plate 14 presents a generally flat circular. face at the front of the machine against which a cutter Wheel 16 rotates. This wheel is mounted upon an axial bolt 17 extending from the center of the face plate 1 1 and is preferably provided with a rim 18 which may have a circumferentially grooved portion 19 in casethe cutter wheel is to be driven by a belt. also provided for hand rotation of the cutter wheel and for cutting purposes this wheel A crank 20 is has its web radially separated and formed with inclined cutting blade'sQl as seen in I Fig. 6 which are laterally deflected toward the face plate 14: and uniformly inclined in the direction of rotation of thecutter wheel as indicated by the arrow in Fig. 1 so that it thus becomes apparent the entire series 1 of blades 21 maybe resharpened from time I p gradually tapers'and isof decreasing depth from the communicating end of the hopper feed channel, thus decreasing gradually in depth in the direction of rotation of the out ter wheel as shown so that as the articles are sliced they are automatically shifted by the action of the cutter wheel along the 1 gradually decreasing slot and thus automatically fed into the effective plane of rotation of the blades 21 down to the last bit of vegetable of fruit as will be seen bya comparison of the dotted line positions in Figure 5.

The wall of the feed slot 13 is moreover provided with teeth 22 inclined as particularly seen in Fig. 5 in the direction of rotation of the cutter wheel 16 and consequently in the direction of shifting movement of the articles being sliced so that by virtue of these teeth undesirable rotative or shifting movements of the articles which might re sult in inaccurate and ununiform slicing is avoided. V

By curving the feed slot 13 of the face plate 14. as above described the articles being sliced will more naturally and more readily follow rotary movement of the cutter Wheel 16 and by arranging the lower discharge channel of the hopperpn a spiral with one end communicating with the dis charge slot it is quite obvious the articles 7 will readily and freely find their way into the slot of the face plate so as to avoid lying upon the weight of articles within the hopper to cause a proper feed thereof from the hopper. This permits of effective slicing of the last-article within the hopper as well as the first.

It is obvious from the foregoing that our invention provides a machine which may be readily operated, which may be formed of cutter, and a hopper having a feed channel and also having a, vertical faceplate at one side against which the cutter rotates, said face plate provided with a feed slot at its lower portion below the axis of the cutter communicating at one end with the said channel and gradually decreasing in depth therefrom in the direction of rotation of the cutter.

2. A' vegetable slicer including a rotary cuttergand a hopper having afeed channel andzalso having a face plate against which the'cutter rotates, said faceplate provided with a feed slot communicating. at one'end with the said channel and gradually decreasing in depththerefrom in the direction of rotation of the cutter, the wall of which slot having teeth vinclined in the direction of -m'ove1nentofthe cutter as described.

3. A vegetable slicer including a rotary cutter having a fiangedrim and having its wall within the rim radially separated and laterally displaced to form cutting blades, a hopper having a generally flat face plate against which the rim and blades of the cutter wheel are movable, said hopper having a lower discharge channel and said face plate having a feed slot communicating at one end with the discharge channel of the hopper and gradually decreasing in depth away from the said channel and in the direction of rotation of the cutter wheel. i

4. A vegetable slicer including a hopper having a circular face plate at one side of its lower portion and also provided'with a spiral discharge channel in its base, said face plate having a curved feed slot in its face communicating at one end with the discharge channel of the hopper and gradually decreasing in depth from the said channel, and a cutter wheel mounted to rotate against the face plate, having cutting blades inclined toward the latter in a direction correspond ing'to the taper of the said feed slot as described. i i 5. A vegetable slicer including a hopper having a circular face plate at one side of its lower portion and also provided with a spiral discharge channel in its base,'said face plate having a curved feed slot in its face communicating at one end with the discharge channel of the hopper and gradually decreasing in depth from the said channel, and a cutter wheel mounted to rotate against the face plate, having cutting blades inclined toward the latter in a direction correspondin to the taper of the said feed slot, said feed slot having its wall provided with teeth inclined in the direction of its taper as and for the purposes set forth.

In testimony whereof we have affixed our signatures. Y a
