VEGETABLE SHREPDER Application filed December 18, 1929. Serial-No. 415,066.

This invention relates to vegetable and meat-cutters and comminutors, and more es-.

pecially to an improved type of grater for domestic use. 5 An object of the invention is the provision of an unusually simple and inexpensive shredder, which is possessed of novel, meritorious features-such as removability of the shredder plate from the frame of the instruferent shredder plate; withthe result that several different classes of work may be performed by my improved shredder, by merely selecting and mounting in operative position, the appropriate type of shredder plate. Another object is the provision of a shredding device in which the shredder plate is removable as described, in which the means for removably mounting the plate upon the frame, are so designed that the selected plate may be substantially instantaneouslymounted in operative position upon the plate, and

removed therefrom.

The invention possesses other objects andadvantageous features, some of which, with those enumerated, will be set forth in the following description of the inventions particular embodiment which is illustrated in the drawings accompanying and forming apart of thespecificatlon.

Referring to the drawings:

Figure 1 is a front elevation of a shredding device constructed in accordance with the principles-of the present invention.

Fig. 2 is a rear elevation. I

Fig. 3 is a longitudinal, medial sectional view taken upon t e line 3-3 of Fig. 1, with the direction of view as indicated. I

Fig. 4 is a front elevation of the frame of bodiment of the. invention, my shredding dement, to permit its being replaced by a dif-- the shredder after the shredder plate has vice comprises a frame 11, and a shredding plate 12 adapted to be removably mounted thereupon. The frame 11 is constructed of .a suitable length of wire bent in such a manner as to form a pair of opposed, spaced side members 13, which are straight throughout a material length thereof, and which are disposed in parallelism with each other. The

side members 13 are retained in spaced relationship by means of a lower end 14, which, as shown upon Fig. 3,is offset from the common plane of the side members 13, being set backtherefrom by angular extensions 16 of theside members 13. The side members 13 are retained spaced at their upper ends, through the expedient of a portionl? of wire extending therebetween, thisportion 17 having a loop 18 therein to provide a handle, permitting the frame 11 to be readily and easily retained in convenient operating position by one hand. The handle 18 is deflected so as toextend angularly rearwards from the frame'll, as is also best shown upon Fig. 3. From the base of the handle 18, the portion 17 of the wire, slopes to meet the upper ends of the side members 13 of the frame, so that in effect, the upper end of the frame 11 is pointedhwith the handle 18 extending from the point. The frame 11 is also provided with a pair of stops .19,spac,ed equally from the lower end 14 of the frame and disposed upon the opposed side members 13, these stops being utilized to limit the downward movement of the shredding plate 12 when mounted in operative position upon the frame 11.

The shredding plate 12, a plurality of which, of different types, may be adapted for mounting upon a single frame 11, is in the form of a preferably flat plate 21. 'This plate 21 is adapted to be easily and removably mounted upon-the frame 11, through the expedient of curling the two lateral edges 23 to form flanges 24 extending rearwards ,from the plate 21, preferably throughout the entire length of the two side edges 23. The 'plate 21 is of such width that the effective distance between the two opposed flanges 24, corresponds to the width of the frame 11, thereby permitting the side members 13 of elevated from the plane of the plate.

as to substantially conform to the cross-sectional configuration of the Wire of which the side mbmbers 13 are formed, thus establish=' ing more secure engagement therewith; and each of thefla-nges 24 is of such dimensions that it extends substantially half way around the associated side member 13. As a result of this construction of the flanges 24, a selected shredding plate 12 may easily be mounted upon, or removed from the frame 11, simply by sliding the plate 12 longitudinally onto the frame 11, with each of the side members 13 of the frame 1 ing within the curvature of one of the anges 24:. The plate 12 should be slid onto the frame 11 from the top end, and the sliding of the plate continued until the bottom edge of the plate engages the stops 19, the parts preferably being so proportioned that when the bottom edge of the plate 12 so engages the stops 19, the upper edge 26 of the plate, which also is preferably pointed, will substantially conform to the upper end of the frame ll- A flange 27 may be formed upon each of the sloping sides of the upper'edge 26, by curling these edges downwardsthroughout the major portion of their length, in such a manner'as to cause the flanges 27 to engage the sloping portions of the upper portion, 17 of the wire framework 11. The parts should be so proportioned that the flanges 27 engage the upper portion 17 of the wire framework, at the same time that the lower edge of the shredding plate 12 engages the stops 19; with the result that the stops 19 and the flanges 27, cooperate with each other in retaining theshredder late 12 in operative position upon the wire rame 11.

The shredding plate 12 is provided with preferably a plurality of -cutting edges 31. These cutting edges may conveniently be formed by punching or otherwise forming a plurality of holes 32 in predetermined arrangement throughout theefiective area of the plate 21. Preferably, the holes 32 are arranged in rows as illustrated. After the holes 32 have been punched, the material of the plate 21 immedlately below each of the holes 32, is pressed toward the front of the plate, e.,lisstruck upwards therefrom, so

that the lowermost edge of each hole 32, is

The edges 31 thus formed, will be relatively sharp because of the fact that as the materialof the plate is struck upwards from the plane thereof, it is necessarily stretched to a certain extent, reducing its thickness as compared to the thickness of the remainder of the plate. Preferably, the portion 33 of the plate 21, which is struck upwards below each of the holes 32, corresponds in width to the diameter of the associated hole 32, but is mate 'rially longer,'thereby facilitating the passage through the hole 32, of the shred or slice of material which the associated cutting ed e 31 has cut.

t is obvious that by supplying a plurality of the'shredding plates 12 with them respective holes 32 of different sizes, and with the cutting edge 31 struck upwards different distances from the plane of the respective plates, shreds and/or slices of various thicknesses andwidth, may be formed.

Each of the plates 12 is reinforced along its loweredge byforming a bead 36 thereon. This may easily be done by simply curling the lower edge over against the rear surface thereof, as shown upon Figs. 2 and 6. "Furthermore, each of the plates 12 is provided with an aperture'37 adjacent the upper edge .26 thereof, to facilitate hanging one or a plurality of plates in any convenient location.

Whereas the device is designed primarily for slicing and shredding vegetables, it will readily be appreciated that it may be employed for performing this operation upon a wide variety of materials. It is utilized by supporting the frame 11 with the handle 18 thereof, in one hand, and the offset lower end 14 resting upon a suitable supporting surface which may be the bottom of a,bowl or other receptacle into which the shredded material is to fall. The article to be shredded is then reciprocated up and down, in contact with the front face of the shredding plate 12, so

that it encounters the various cutting edges 31, each of which cuts a shred of material from the article. Each of these shreds passes through the associated hole '32 and falls into the receptacle or onto the supporting surface upon which the frame 11 is supported.

Owing to the relatively large number of I cutting edges 31 which may be provided in each of the shredding plates 12, this shredding operation is carried out with the utmost ease and rapidity. The removability of the shredding plates 12 from the frame 11,. permits not only the selection of the desired shredding plate to produce shreds of the desired size, butit also materially facihtates cleansing and sterilizing the entire device.

It is to be understood that the details of the invention as herein disclosed, are subject to alteration within the spirit or scope of the appended claims.
