Improvements in Vegetable Cutters and Slicers.
I, JOHN GULICK BAKER of 1922 North Seventh Street in the City of
Philadelphia, State of Pennsylvania, United States of America Mechanical
Engineer do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in
and by the following statement:
1
The object of my invention is to so construct a vegetable cutter having a rotary
knife carrier that the knives will operate with a shearing action and can be readily
adjusted to vary the depth of cut, the device moreover being cheaply and simply
constructed and readily taken apart for cleansing purposes.
In the accompanying drawings:
Figure 1 is a perspective view of a vegetable cutter constructed in accordance
with my invention.
Figure 2 is a vertical section of the same;
Figure 3 is an inverted sectional plan on the line 1-2 Figure 2 with the
supporting frame broken away and
Figure 4 is a view shewing a modified form of cutter.
A represents a bracket arm provided with a clamp whereby it may be attached
to the edge of a table or other support, the said bracket carrying a guide trough B
and being provided with a guard rim D as shewn in Figures 1 and 2.
The upper end of the bracket forms a bearing a for a vertical shaft or pin F and
upon
the upper
end of the latter is mounted a disk G to which is secured a series
of depending segments I four of which are shewn in the present instance although
there be more or less than this if desired.
Each segment has at the upper end an inwardly projecting flange ba bolt d
passing through this flange and through the disk G and serving both to support
the segment and to pivot the same to the disk so that it can be swung thereon in
order to cause its forward edge to project more or less beyond the rear edge of the
preceding segment.
The forward edge of each segment I is sharpened so as to act as a cutting knife,
and is inclined in order to insure the shear cut necessary in order to properly slice
cabbages or like vegetables, the pivot bolt d being situated at a point about
midway of the extreme ends of each segment so that the differential movement of
the front or cutting edge of each segment due to the inclination of the same is
counterbalanced by a reverse differential movement of the rear edge of the
preceding segment, hence the extent of projection of each cutting edge beyond the
preceding segment will be substantially uniform from top to bottom.
As a means of effecting the adjustment of all of the segments simultaneously
I provide the shaft F with a disk J which is fixed to the shaft and has a series of
cam slots for the reception of pins i projecting from tails on the flanges 6 hence
by moving this cam to the right, the segments will be caused to swing in one

page_text: direction, and by moving it to the left the said segments will be caused to swing in
the opposite direction each segment being positively controlled so that the extent
of projection of the knives and the consequent depth of cut can be very readily
regulated.
A crank M is secured to the squared upper end of the shaft F by a nut m and
the hub of this crank bears upon the hub of the disk G so that when the nut m
is tightened the crank and disk are secured together, but when the nut is slackened
the crank can be turned independently of the disk, so as to effect the operation
of the disk J and the adjustment of the cutting segments, the disk G being held
so as to prevent its rotation while such adjustment is being effected.
The cuttings are directed by the knives to the interior of the open bottomed
drum formed by the disk G and the series of segments I and the said cuttings
drop from the drum into a receptacle situated beneath it, the lateral scattering
of any of these cuttings being prevented by the guard rim D which extends some
distance above the bottom of the drum as shewn in Fig. 2.
The cutting drum with its shaft or pin can be readily lifted from the bearing a
of the bracket so that ready access to the interior of the drum at all times can be
had for cleansing or other purposes.
A block M of wood is adjustably secured to an inclined bearing at the front
end of the trough B so that it can be moved towards or from the cutting drum,
and thus form a bearing for the material close up to the surface of the drum,
this block also serving to prevent injury to the knives such as would result if
they came into contact with a metal bearing plate.
Special cutting knives, such as shewn for instance at n Fig. 4 may be secured
to the segments I when it is not considered practicable or advisable to form the
cutting knives by the segments themselves, and the cam disc may, if desired be
formed as shewn at J in the said figure, so as only to project the segments I,
the latter being pushed inward by hand, although of course the form of disc
shewn in Figures 1 to 3 is preferred.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A rotating drum for a vegetable cutter, consisting of a disc having segments
pivoted thereto, each segment having inclined front and rear edges, the front
edge forming or carrying a cutter and the rear edge serving as a guard for the
cutter of the following segment.
2. A rotating drum for a vegetable cutter, consisting of a disc having segments
pivoted thereto, cach segment having an inclined front edge forming or provided
with a cutter and a correspondingly inclined rear edge forming a guard in com-
bination with a cam structure, acting upon the segments so as to simultaneously
adjust the same, either in one or both directions.
3. The combination of the fixed structure comprising the supporting frame,
with its guide trough and upwardly projecting shaft bearing, with a cutting drum
consisting of a disc having a depending shaft adapted to said bearing and a
series of depending segments pivoted to the disc and having inclined front edges
forming or carrying cutters and inclined rear edges serving as guards.
4. In combination with the disc having the depending pivoted segments and
adjusting cam the construction or arrangement whereby the same bandle which
serves to rotate the drum, is also available for operating the cam to adjust the
segments.
