1Claim.

This invention relates to and has for an object the provision of anovel and highly emcient ma- Y chine for cutting or slicing various objects and food stuff and more particularly for slicing potatoes, apples and other vegetables and fruits.

An object of the invention is to provide a slicing machine of thecharacter described which will not crush or bruise the potatoes etc. during the slicing operation.`

Another object isto provide a machine of the character described in which the friction set up in forcing the potatoes or other objects through the slicer or cutter is reduced to an appreciable minimum whereby to reduce the operating force or manual eiort and to make possible a iiner cutting and slicing action than heretofore possible with vegetable slicers and the like.

A further object is to provide a cutting or .slicing machine having a novel form of cutting or slicer unit made up of an open frame across wlch thin and narrow blades are stretched and secured under high tension, said blades having sharpened cutting edges and offering a minimum of resistance to the forcing therebetween of the object to be sliced thereby.

Yet another object is to provide a cutting or slicing machine of the character described wherein the cutter or slicer may beA comprised of one or more of said slicing units in a novel and eiicacious relative arrangement providing for a smooth and uniform slicing of a potato or the like which is forced therethrough the blades of one unit being spaced from the blades of the other unit when more than one of said units is employed whereby one set of blades acts as a guide and support while the other set is slicing. With the above and other objects in View the invention subsists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawing and set forth in the claim hereto appended, it being understood that various changes in form, proportion, siz'e and minor details of construction Within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Referring to the drawing: Figure l is a side elevation of theslicing machine. l

Figure 2 is a sectional view taken on the plane of line 2-2 of Figure. 1.

Figure 3 is a front end elevation of the machine.

Figure 4 is an'elevational view of one of the cutter umts.

Figure 5 is an elevational view of another o1' the cutter units.

Figure 6 is a fragmentary side elevation showing the manner of'swaging the ends of the blades in the frame therefor.

5 Figure? is a full size fragmentary sectional view further showing the manner inl which the blades are attached to the frame therefor and the relative width of the cutting blades.

The present embodiment of the invention asV shown in detail in the accompanying drawing comprises a base I on which a frame Y2 is mounted, said frame including M-shaped standards 3 joined by rods 4 and supporting a. V-shaped guide or trough 5 consisting of spaced bars 6 secured at their ends to the oppositely inclined portions 'I of said standards.

The guide 5 is adapted to guidingly support the potato or other object to be, sliced while said potato or other object is forced, by the toothed extruding block 8, thru the slicing means 9 located at one end of the frame. The slot provided by the spacing of the guide bars 6 permits of ready and sanitary cleaning and clearing of the machine after use.

The block 8 'is removably secured to a carriage I6 slidable on rods 4,'said block having a. working iit with the guide 5. As here shown the block is adapted to be manually operated by a lever II pivoted at I2 on lugs I3 extending from one of the standards 3, there being a link connection III between the carriage I and said lever.

It will vnow be seen that when a potato or other object to be sliced is placed on the guide between`the block Band slicing means 9, the lever I I may be readily manipulated to cause the block to force the potato or other object thru said slicing means.

The slicing means as here shown is comprised of separate cutting or slicing units I5 and I6 each of which is identically constructed except that the blades II of the unit I5 are disposed to ext-end angularly across the blades I8 of unit I6 when the two units are employed as shown in Figures 1, 2 andy 3. Each unit comprises an open metal frame I9 having the blades extending thereacross in spaced parallel relation to one another and held therein under high tension', say of about 300 pounds. Preferably each blade is seated in saw cuts as at in the frame therefor and l `placed under said high tension then swaged or otherwise secured, thereby to remain under such tension.

It is important to note that said blades are decidedly thin and narrow the thickness thereof being for example of 28A gauge saw steel'while the width thereof is not more than three thirtyseconds of an inch. Buch narrow blades will offer a minimum of resistance to the object being forced there-between during the slicing of such object.

When-more than one slicing unit is used, say the two units as here shown, the frames are slipped upon the projected ends of the rods l so that the inner unit frame rests against the adjacent standard l and is separated from the other unit by a thin spacer 2l. Wing nuts 22 are then turned on the threaded ends of said rods to hold the cutter units assembled.

It will be noted that the blades of one unit have sharpened cutting edges that are substantially flush with one side of the frame therefor whereas the blades of the other unit have their sharpened cutting edges reversely arranged, the unsharpened edges thereof being flu'sh with one face of the frame therefor. Thus when the two frames are arranged as here shown; the cutting edges face the object being forced by the block 8 and one set of blades cuts in advance of the blades of the other set, the former acting as supporting guides while the latter cut. Further, the friction caused by cutting, two ways simultaneously wherein the corner'cutting operation is effected by two sets of blades, the cutting edges of which lle in the same plane, is eliminated.

Due to the narrowness and thinness of the blades theforcing of the object -thru the cutters or slicers is accompanied by a minimum of friction and it is therefore possible to closely space the blades and provide for a? fine slicing action such as desired in making a shoe string slice of potato or other object.

Whereas two cutting units are shown, but one may be used if desired and the spacing and relative arrangement of the blades may be varied.

whereby to produce slices of different shapes and sizes all within the scope of the invention.

It is important to note that the blades of the innermost .unit have their cutting edges on a common plane spaced forwardly of the corresponding plane of the cutting edges of the blades of the outer unit. whereby the lslicing is done in two planes relatively spaced by the spacers 2i.

' As aforesaid the blades are thin, sharpened and narrow, and the unsharpened backs of the blades present very fshort restricted passages thereby reducing friction. In the use of two cutter units the provision of the two planes ofcutting action in spaced relation permits the slices, cut by the first set of blades, to expand freely before subjection to the cutting action of the second set of blades; but, at the same time, the first set of blades supportingly guide the material and a smooth and easy cutting action is thereby assured.

We claim:

In a slicing machine of the class described, the combination of a fixed, rigid, rectangularly shaped, open frame memberprovided with slots in one side thereof, means for supporting it at two of its corners, blades secured at their ends across the open space in said frame member in spaced relation to each other and secured in tension in said slots in one side of said frame member so that one side is flush with the side of said frame member forming a cutting member, another similar cutting member with the slotted side adjacent the slotted sides of the rst mentioned frame member and arranged with the blades at an angle to the blades in the first mentioned frame member, said blades being sharpened at their receiving edges, a reciprocating block provided with a face portion adapted to fit in the open space in said frames and provided with forwardly extending lugs arranged to fit between the blades in both of said frame members and substantially flllthe same, means for guiding said block, consisting of substantially V- shaped guide frame 1n which said mock 1s reciprocally mounted with one corner downwardly vvtherein, and rods-positioned above said guides lupon which said block is shiftably mounted for guiding said block in certain relation with said guide members.
