CUTTER AND SHREDDER.

Specification of Letters Patent.

Patented Feb. 10,1914.

Application led November 27, 1912. Serial No. 733,822.

To all 107mm t may concerny Beit known that I, HARVEY M. DE Linn, of 313 Kellogg street, Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful improvements in Cutters and Shredders, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

rlhis invention relates to certain improvements in cutters and shredders, and pertains more particularly to that class of machines used for cutting and shredding vegetables, as cabbage.

The object of my invention is to provide a simple and improved machine whereby the material operated on may be either cut, shredded, or cut and shredded, with great regularity and rapidity.

A further object is to provide means for.

holding the knives or knife supporting members firmly but removably in operative posit-ion.

Another object is to provide means for supporting the cutting knives in predetermined positions relative to each other.

Other objects and uses will appear from the following description In the. drawings-Figure 1 is a perspective view of the machine. F ig. 2 is a cross section on line 2 2, Fig. l. Fig. 3 is a cross section on line 8 3, Fig. l. Fig. 4L is a cross section through one of the cuttingknife supporting members, showing the means for holding the knife in place. Fig. 5 is a similar section adjacent the knife plate. Fig. G is a view of the angle bar of the cutting-knife supporting member, showing the slots for receiving the knives. Fig. 7 shows the dog seated in a groove in the angle bar for holding the knife supporting member in operative position. Fig. 8 is a perspective view of the shredding knife, showing the groove in which a pivoted dog is seated for holding the knife in place. Fig. 9 shows a slightly different construction for holding the knife or knife supportinol member in operative position, comprising a spring adapted to resiliently close the opening in which the knife or knife supporting member is seated.

rlhe machine comprises a bodf,r -lof sheet metal, wood or other suitable material, having supporting legs 2- fastened thereto in any suitable manner, as by screws 8-- The body llis provided with bearings --lw for the reception of a shaft -5-, having one end provided with any suitable driving member as a pulley -6-. Keyed to the shaft by means of set screws -7-, are circular sheet metal plates 8- and -9- having connecting rods as l0- uniting them firmly together. Each of the cylindrical plates -8- and -9- have coacting apertures -lO- and ll-, the aperture -11- adapted to receive a shredding knife -12-, having a groove 13- in one edge thereof for receiving a dog i4- adapted to hold the knife in place.

The cutting knives 15 are formed preferably of thin sheet metal and have a substantially semi-circular outer portion adapted to form the blade of the knife.

The supporting member for the cutting knives -15- is formed of an angle bar -16- having' slots 17- therein for receiving a knife. Each knife -15- is provided with a groove -l8-upon its opposite sides, forming projecting flanges -19-- upon the blade portion of the knife and `QO-upon the rear portion thereof. The side -21- of the angle bar 16- is adapted to fit in one of these grooves and a sheet metal strip 22- is adapted to fit in the other and is held in position between the iianges 19- and -20-. The angle bar 16- and the strip -22- are connected for holding the knives in operative position, by any suitable means as bolts -23-- One end of the knife bearing member is then inserted from the inner side into an opening --lO- in one of the plates as -8- and pushed through a sufiicient distance until the other end is in position to b e inserted in a corresponding opening -10- in the plate -9-. A dog -28- pivoted to the plate -8- is then pushed over until it engages a groove -24 in the angle bar 1G- for holding the knife bearing member in operative position. The device is provided with a cover -25- hinged in any suitable manner to the body -land adapted to partially cover the rotating member.

In Fig. 9 I have shown the cutting-knife supporting member, comprising the angle bar -21- and the plate -22-, resiliently held in the openings -10- by means of a metal strip -26- attached to the plate -S- in any suitable manner, as by bolts -27- and it is readily apparent that the knife supporting member may be inserted in o-ne of the openings and pushed forward against the action of the spring 26 until the other end is in position to be inserted in the corresponding opening l0- in the other plate, and that the springs will resiliently hold the knife supporting member from movement in either direction.

It will be readily apparent from the above description that the shredding knives 12- may be used without the knives 1Q- or that they may be used in combination with the knives -19- for cutting and shredding at the same time, and that the bottom w29# of the body portion coacts with the knife l2- for positively cutting the material and at the same time acts as a support for the material adapted to be cut.

The angle bar -16- may be provided with any suitable number of slots and knives may be inserted in as many of these slots as is desirable, depending upon the size of the pieces intowhich the material is sought to be out.

The operation of the cutting knives is greatly facilitated by reason of the rapid drawing motion, effected by the peculiar shape of the knife, the rotation of the frame causing not only a downward motion of the cutting knife, but a sawing motion by reason of the semi-cylindrical form of the knife blade, whereby the material is more readily and positively cut.

What I claim is:

l. In a vegetable cutter, a rotary frame comprising a pair of substantially circular disks, means for rotating said disks simultaneously, said disks provided with registering openings wholly within the body of the disks, a removable knife seated in said openings and means mounted on one of said disks for preventin movement of said knife in the direction of); its length.

2. In a cutter and shredder, a rotary frame, alined openings extending through said frame, a cutting-knife supporting member mounted in said openings, a plurality of circumferentially extending cutting-knives engaged and held in operative position by said member, and means for holding said supporting member against transverse movement.

3. In a cutter and shredder, a rotary frame, a knife supporting member mounted thereon, comprising an angleV bar having slots therein, knives, having grooves in their opposite sides, seated in said slots, one side of the angle bar seated in one of the grooves in the side of the knife, a plate seated in the groove upon the other side of the knife, and means for connecting the angle bar and the plate for positively confining the knives.

t. In a shredder, plates journaled on the same axis, said plates provided with openings alined to receive a knife, a knife having a groove therein seated in said openings, i, dog mounted on one of said plates and rotating therewith and seated in the groove in the knife.

5. In a vegetable cutter, a shaft, disks mounted on said shaft and rotating therewith and spaced apart to form a rotary frame, said disks provided with alined openings extending through the disks, a removable knife seated in said openings, means for preventing transverse movement of the knife and a vegetable supporting table located at one side of said frame and below the axis thereof.

6. In a vegetable cutter, a rotary frame having end disks spaced apart, alined openings in said disks, a cutting knife supporting member mounted in said openings, a plurality of circumferentially extending cutting knives engaged and held in operative position by said supporting member, and means mounted on one of said disks for preventing movement of said supporting member in the direction of its length.

7. In a vegetable cutter, a shaft, a pair of spaced disks, mounted on said shaft and y rotating therewith, rods connecting said disks to form a rotary frame, said disks provided with registering openings, a removable knife seated in said openings, a groove in said knife and a dog pivotally mounted upon one of said disks and adapted to lie in the groove for preventing transverse' movement of the knife.

8. In a rotary cutter, a shaft, a pair of spaced heads connected for simultaneous rotation, a plurality of registering openings in said disks, a longitudinally extending knife mounted in one of the openings in each plate, means mounted on one of said plates for preventing transverse movement of said knife, a knife-supporting member seated in an opening in each of said plates, means mounted on one of said plates for preventing transverse movement of said member, and a plurality of axially extending knives supported by said member.

9. In a vegetable cutter, the combination of spaced disks having registering openings, a removable knife seated in said openings, a groove in said knife and a dog pivoted to one of said disks and operably positioned in the groove in the knife.

10. In a vegetable cutter, a rotary frame comprising a pair of substantially circular heads Connected for simultaneous rotation,
