VEGETABLE SHREDDER
Abstract
A shredder is constructed from a thin sheet of metal which is
punched to provide slicing and shredding openings in different
areas and is shaped to have the flanges at the free ends spaced by
a supporting bar having a handle thereon by which the shredder is
supported when the different areas are being used. A closure door
may be provided on one end of the shredder pivoted to the
supporting bar with a spring between the bar and an operating
projection by which the closure door is opened. The bar and handle
may be made of wood but preferably is made of a plastic material
which is molded to provide a hollow interior so as to be light in
weight. The two flat sides having the cutting and shredding areas
are joined by an arcuate bottom section which may be hardened to
retain its shape or having the ends strengthened by a formed wire
so that the cross section is maintained for engagement by the
closure door which preferably has a flange about the edge.

stamped therein, a supporting bar between said flanges having
apertures aligned with those in the flanges, and rivet means in
said apertures for securing the flanges and supporting bar
together.
2. In a shredder as recited in claim 1, wherein a closure door for
one end of the shredder is pivoted to the supporting bar, and
spring means for urging the closure door to closed position.
3. in a shredder as recited in claim 2, wherein the bottom wall of
the device is of semi-cylindrical form.
4. In a shredder as recited in claim 2, wherein the side walls are
elongated being of greater length from end to end than from side to
side, and wherein the bottom wall of the device is flat and
disposed in triangular relation to the elongated sides when
assembled on the supporting bar.
5. In a shredder as recited in claim 1, wherein the supporting bar
has a central handle provided thereon by which the shredder is held
when in use.
6. In a shredder as recited in claim 2, wherein the operating areas
have cutting edges which cut in the direction toward said end
closure door.
7. In a shredder as recited in claim 5, wherein the bar and handle
are formed of a plastic material in a manner to have the bar and
handle of hollow construction to reduce the weight thereof.
8. In a shredder as recited in claim 6, wherein a recess is
provided in the top end of the bar and wherein the closure door has
an operating extension and a compression spring secured between
said extension and bar.
9. In a shredder as recited in claim 2, wherein the side edges of
the sheet are reinforced by a formed wire to maintain the form of
the flat sides and semi-cylindrical bottom section.
10. In a shredder as recited in claim 2, wherein the closure door
is provided with a flange which extends over the adjacent end of
the walls.
Description
BACKGROUND OF THE INVENTION
Shredders have been provided heretofore which are rectangular in
shape tapered toward a smaller end at which a handle is provided
with the opposite end formed about a rectangular wire frame to
provide rigidity and with each of the four sides provided with
different slicing and shredding areas.
SUMMARY OF THE INVENTION
The present shredder is made of thin metal and stamped to provide
slicing areas and areas which have been punched out to provide
protuberences which are broken open at the top to produce a
shredding operation, the projection and openings being greater in
one area than in the other area. After the sheet is stamped in this
manner with additional punched openings provided in a flange at the
opposite ends for rivets, the flanged ends are brought together and
riveted to a supporting bar. The bar has a handle midway between
the ends by which the shredder is held while fruit, vegetables or
the like are being shredded or sliced thereon. Since the handle and
the slicing and shredding areas will be disposed vertically when
being used, the bottom end of the formed sheet is covered by a
hinged closure door which is spring pressed to closed position and
which has a tab or projection by which the closure door is moved to
open position. The sheet has two flat sides when supported on the
bar with an arcuate semi-cylindrical bottom portion which has
sufficient rigidity to retain its form. When the metal is of a very
thin grade, a reinforcing wire may have the metal at the opposite
ends rolled thereover to maintain the arcuate form. It is within
the purview of the invention to have the two flat walls joined by a
third flat wall across the bottom which forms a triangle which is
rigid when secured to the supporting bar. The closure member will
be the shape of the bulbous or triangular form and will preferably
have a flange about the edge which extends over the edge of the
formed sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1, 2 and 3, the shredder 7 of the present
invention embodies a very thin sheet 8 of stainless steel or like
material which is stamped and formed to provide cutting areas 9 and
10 and shredding areas 11 and 12. The material is bent along the
line 13 to provide end flanges 14 which have apertures 15 punched
therethrough at spaced points. The flanges 14 are disposed against
the sides of a supporting bar 16 having apertures 17 therethrough
through which rivets 18 extend and through the apertures 15 in the
flanges 14 to secure the ends of the sheet to the bar. The central
portion of the bar has a handle 19 by which the entire cutting and
shredding device is supported. The bar 16 may be made of any of a
number of plastics such as polystrene, impact polystrene,
polyamides, e.g., nylon, or may be cast from vinyl plastisols or
the like, or molded in holllow form so as to be light in
weight.
Since the operation is to occur lengthwise of the formed body 21,
the bottom end 22 is provided with a closure door 23 which is the
shape of the body 21. The body 21 has oppositely disposed sloping
sides 24 joined at the bottom with a semi-cylindrical section 25.
The closure door 23 has an edge flange 26 and an operating
extension 27 which has a U-shaped saddle 28 welded thereto which
spans the end of the supporting bar 16. A rivet 29 extends through
an aperture in the projecting ends of the saddle 28 and an aperture
in the end of the supporting bar 16. The operating extension 27 has
a punched-out projection 31 aligned with a recess 32 in the bar 16
for supporting a spring 33 which biases the closure door 23 to
closed position. By pressing on the operating extension 27 the
closure door 23 swings outwardly from the closed end to permit the
sliced or shredded material to pass from the interior of the
shredder. It is within the purview of the invention, as illustrated
in FIG. 4, to eliminate the semi-cylindrical section 25 of the body
21 and provide a flat bottom wall 34 in lieu thereof which forms a
triangle with the two sides 24 to provide rigidity to the
construction. The bottom wall 34 may be provided with a cutting or
serrating surface which adds to the usefulness of the device. In
FIG. 5, the ends of the sides 24 and bottom section 25 are shown
coiled around a formed wire 35 to provide rigidity to the ends and
sections therebetween.
In operation, the closure door 23 will rest upon a board, a pan or
the like and be held by the handle 19 while the slicing or
shredding occurs which may require a substantial force. When the
operation is completed, the device may be carried by the handle to
a receptacle where the closure door 23 can be opened by pressing
upon the operating extension 27 so that the sliced or shredded
material can be expressed from the end. The flange 26 may be
eliminated at the bottom of the closing door so that the material
may readily slide therefrom.
