An object of this invention is to prvoyide .inproved means for slicing vegetables, particularly potatoes.

ii. turther object or' this invention is: to provide improved mea-ns for slicing and split-ting the slices of vegetables, particularly potatoes.

i further object` ot this invention is to provide' a slice-splitting assembly or"l attachment/adapted to be used selectively in respect of a slicing machine.

further object otY this invention is to provide an improved machine for' preparing potatoes for French-tries.

' A further object otthis invention is to provide an improved machine 'for prepar- 'mg potatoes Vtor shoestrings,

My invention consists in the construction, arrangement and combination ot elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing', in which- Figure 1 isV an end elevation of the complete machine, dotted lines indicating the location ot two splitting assemblies. Figure 2 a vertical section on the indicated line i 2 ,of Figure 1. Figure 3 is an edge view a fragment ot a disc and parts carried e"eby on an imaginary line 3-3 of F ig- 1, wliicn line is tangent to the disc. Fig- Ll is a section on the indicated Aline 4--1 'fe 1, oit the disc and parts carried y Figure 5 is a. cross-section of ynient ot' the disc and parts carried thereby, on the indicated line 5 5 ot Fig- Figures 3, il, 5, are drawn to a very much enlarged relative to Figand 2.

ln the yconstruction of the machine as rhown the numeral designates generally a supporting 'trame which may be of any bl" size, Jtorni and construction. An

shaft 11 is journaled inany suition on the trame 10 and is driven sly in onedirection by anysuita eniet A disc 12 ot any suitable size and relative thickness is mounted rigidly on lone end of and is driveny by the shaft Suitable slicing and'splitting devices are mounted on and carried by the disc 12 as hereinafter described. A tace plate 13 is mounted parallel with and spaced from the outer face ot the disc 12 and is formed with a tapering opening ,at one side of the center of said disc and also is formed with a. ramper 'ifi mi its er face opening im wardly through said opening in the plate. ihe disc 12 is formed with a plurality of radial slots, in this instance two in number, iniflicated by the dotted outlines ot' rectangular torni in Figure 1. One of the radial slots is shown by dotted lines in Figure 3,

and by solid lines inFigures 4 and 5 and is indicated by the numeral 15. A cutting blade 16 is formed with abody portion substantially' cor'responcing'in length with a slot and having richt-angled armsl? on its endsv and ears 18 at'r'ight angles to the extremities of said arms. The arms 17, one ot which is shown in vFigure 5, extend through a slotlg) from the inner tothe outer 'surface thereof and locate the body of the lc uttiirg blade 1G`in a plane between the disc 12' and faceplatev 18. The ears 18 overlap on the inner face of the disc 12 at the ends of the slot 15 and are spaced from raid face by elements'l), such as washers or serrated wedges, and '

bolts

20, 21 are mounted through Vsaid ears, spacing elements and discs and have theirheads countersunk in the outer tace of the disc. The disc is adapted to be rotated clockwise and in relation to such movement the'forward margins of the bodies of the cutting blades are beveled on the inside as shown in Figure 4C. The long side walls of the slots 15 are beveled inwardly as shown by full lines in Figurell! and dotted lines in Figure 3. The explanation'thus far goes to the slicing machine 'andV in practical use potatoes are fed to the hopper 14rand project through the opening in theiace plate into the path of travel of the cut-ting blade. In their travel,y

the cutting lades successively cut slices 'from the potato and discharge through a chute 22 forming A a part of the traine. Friction ont the cutting knives and oravity feeds the potatoes from the hopper through the opei'i'ing 'in the tace plate in order that successivemsl'ices may be cut thereirom.`

A splitting assembly is built up as iollows; a pairot end blocks 23, 2li, a plurality of spacing blocks 25, a plurality ot splitting knives 26, a'rod 27, a stabilizing rod 28 and bolts 29, are employed. The assembly'of splitting elen'ient-s .lille the slot 15 trom end to end and is located between the cutting edge yoi! rablade 16and adj aeenty inclined wall of the slot and overlaps part on the inner face of the disc 12 there being one splitting assemblyprovide' foreach slot.v Each of die '

tineke

23, 24 is formed with a tongue 31 of less width than the block and extending obliquely to the body thereof thereby forming a shoulder 32 adapted to abut the end Walls of the slot 15. rlhe spacing blocks are preferably rectangular in form and 01' a Width Corresponding to the Width of the tongues 31 and o1 the length to extend the full length ot said tongues and overlap on and extend across tne bodies olt the blocks 23. 'lhe end blocks 23, 2-1 and the spacing blocks are formed With registering holes adapted to receive the rod 27, which rod is termed as a bolt and is adapted to clamp the assembly together. rThe spacing blocks 25 also are formed with registering hole; on a line paralleling the rod 27- and the end blocks 23, 24- are formed With recesses on their inner faces registering With said holes, said holes and recesses being adapted to receive the stabilizing rod 28 and limit and prevent oscillation of elements on said rods 27, the relation of the stabilizing rod to the holes and recesses being' indicated by dotted lines in Figure 5. It will be observed that the

end blocks

23, 24 are right and lett respectively and are placed back toward back as shown in Figure 5, While the spacing blocks are et uniform shape. The splitting knives 2G are formed with longitudinal slots 33 open at one end and one arm Se ot the saine ot less length than the other arm 35, the latter arm being ,termed With a cutting edge 36 on its outside margi The splitting knives J3 are placed between the

end blocks

23, 2/-1 and spacing blocks in sequence throughout the length ot the assembly, and said lrnives may be so placed and also be removed by longitudinal movement between said blocks in straddling relation to the rods 27, 28. The outer end portion out the arm ot each splitting blade 2G extends beyond the outer tace o1 the disc 12 and across the plane of the cutting edge oit a cutting blade 16. After the end blocks, spacing blocks, splitting knives anu rods are assembled and secured in place and in rigid connection by tightening the rod 27, the entire splitting assembly is mounted on the dic 12 in proper relation to slot 15 and cntt ng blade 16 and secured in place by the

l

29, 30 extending through the end blocks i bolts land having their heads countersunk in the outer tace of the disc. lVhen the machine is equipped with the splitting assemblies' as shown and described and the disc is operated clockvvie, as for slicing, the outwardlyprojecting end portion-31 of the arms 35 penetrate the potatoes on parallel lines and form arcuate slits therein. rllhe next following slicing blade intersects the arcuate slits and severs strips trom the potatoes. The knives may be so spaced in the splitting asieinblies and the cutting blades 16 be so spaced relative to the disc as to vary the cross-section of the strips severed from the potatoes, thus determining the producU in respect oi shoestrings or French tries. ln like manner the spacing of the slicing blades 16 relative to the outer face ot the disc 12, through the employment of more o r less, spacing eleg ments 19, will determine the relative thieliness of a slice removed from the potatoes.

I claim as my invention- 1. A potato slicing machine comprising a face plate formed with feeding hopp in a disc mounted parallel with said plate and formed With radial slots having an orbit coincident with said hopper and a slicing blade mounted on said disc adiacenti each slot therein, each slicing' bla'de being spaced.

'trein the tace ot the disc adjacent saidV plate and Jformed With arms extending through said slots and ears adapted to be adjustably related to and secured on said disc. Y

2. In a machine of the character described, a splitting assembly comprising end blocks, spacing blocks, splitting knives mounted between and extending' beyond said blocks, an assei'nbling rod extending through said blocks and knives, a stabilizing rod extend-V ing through some blocks and through said knives and seated in other said blocks, and means for mounting said assembly in a rotating element, l

3. ln a machine ot the character deF scribed, a .splitting assembly comprising end blocks, spacing blocks, splitting knives mounted between and extending beyond said blocks. an assenibling rod extending through said blocks and knives, a stabilizing rod extending through soine ot said blocks Vand through said 1lKnives and seated in other said blo-chil, said knives being longitudinally sletted and open rat one end, and means ier n'iounting said assembly in rotating elenient.
