This invention relates- to and has for an object
the provision of a’novel and highly emcient ma
Y» chine for cutting or slicing various objects and
food stuff and more particularly for slicing po
tatoes, apples and other vegetables and fruits.
An object of the invention is to provide a
slicing machine of the- character 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 eiîort and to make possible a iiner
cutting and slicing action than heretofore possi
' ble with vegetable slicers and the like.
20 or slicer unit made up of an open frame across
wl‘îch 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 where
in the cutter or slicer may beA comprised of one
or more of said slicing units in a novel and
eiiîcacious 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
35 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, illus
trated in the accompanying drawing and set forth
in the claim hereto appended, it being under
stood that various changes in form, proportion,
si’z'e and minor details of construction Within the
scope of the claim may be resorted to without
45 departing from the spirit or sacrificing any of
the advantages of the invention.
Referring to the drawing:
in the frame therefor. ï '
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 mount
ed, 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
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 lo
cated 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 I0 and said lever.
It will vnow be seen that when a potato or other
object to be sliced is placed on the guide 5 be
tween`the block Band slicing means 9, the lever » 35
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 I‘I 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 45
across in spaced parallel relation to one another
and held therein under high tension', say of about
300 pounds. Preferably each blade is seated in

A further object is to provide a cutting or

“saw” cuts as at 20 in the frame therefor and l 50
decidedly thin and narrow the thickness thereof 55
being for example of 28A gauge saw steel'while the sponding plane of the cutting edges of the blades

width thereof is not more than three thirty
seconds of an inch. Buch narrow blades will two planes relatively spaced by the spacers 2i.
offer a minimum of resistance to the object being ' As aforesaid the blades are thin, sharpened and
forced there-between during the slicing of such narrow, and the unsharpened backs of the blades
present very f‘short” restricted passages thereby
When-more than one slicing unit is used, say
the two units as here shown, the frames are
reducing friction. In the use of two cutter units
slipped upon the projected ends of the rods l
10 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 substan
tially flush with one side of the frame therefor
whereas the blades of the other unit have their
sharpened cutting edges reversely arranged, the
20 unsharpened edges thereof being flu'sh with one
face of the frame therefor. Thus when the
two frames are arranged as here shown; the
the provision of the two planes of‘cutting action
in spaced relation permits the slices, cut by the
first set of blades, to expand freely before sub 10
jection 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
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
cutting edges face the object being forced by
spaced relation to each other and secured in ten
the block 8 and one set of blades cuts in advance
sion in said slots in one side of said frame mem
ber so that one side is flush with the side of 25
25 of the blades of the other set, the former acting
as supporting guides while the latter cut. Fur
ther, the friction caused by cutting, two ways
said frame member forming a cutting member,
simultaneously wherein the “corner”'cutting op
side adjacent the slotted sides of the ñrst men
tioned frame member and arranged with the
eration is effected by two sets of blades, the cut
30 ting edges of which lle in the same plane, is
Due to the narrowness and thinness of the
blades theforcing of the object -thru the cutters
or slicers is accompanied by a minimum of fric
35 tion 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 rela
40 tive 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
.unit have their cutting edges on a
common plane spaced forwardly of the corre
another similar cutting member with the slotted
blades at an angle to the blades in the first men
tioned frame member, said blades being sharp
ened 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 mem
bers and substantially flllthe same, means for
` guiding said block, consisting of substantially V
shaped guide frame 1n which said mock 1s recip
rocally 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.
