This invention relates to a crushing device and
particularly to a device for crushing fruit and
vegetables in order to break down the cellular

In many instances, it is desirable to provide a Cu ring [3 for holding a glass or dish. Rising from,

ture generally designated as 28. Box 29 may
have front wall 2| and rear wall 22, the rear wall
ons and other fruits as well as vegetables, such as _
carrots, spinach, etc. In the case of fruits,‘par
ticularly citrus fruits, it is well known that the
juices thereof are highly corrosive to ordinary
metals and materials. Due to the delicate flavor
of many fruits, contamination with certain
metals imparts an objectionable metallic taste
to the fruit. Furthermore, the highly corrosive
action of citrus juices on metals such as alumi
‘ num and steel results in discoloration and thus
makes it dif?cult to maintain a clean and whole
some appearance of the article.
In addition to the above, it is essential that a
device for extracting juices and crushing fruit
and vegetables and used in homes be relatively
inexpensive, simple, and be easy to disassemble
and clean.
The invention herein provides a
structure which ful?lls the above requirements’
to a remarkable degree.
In addition, the struc
ture is susceptible, to the incorporation therein
of such-construction materials as wood or plastic
whose characteristics for kitchen use are highly
desirable. The use of wood in kitchenware is
particularly advantageous in that tooling costs
10 preferably being higher than the front wall. , A
pair of side walls 23 and 24 extend between the
front and rear walls, and these side Walls are
preferably inclined toward each other as shown
so that a minimum separation is at the bottom
thereof and a maximum separation is at the top.
The'bottom of box 2|] may be covered bv plate
25 having slot 26 extending lengthwise between
walls 2| and 22.
Side walls 23 and 24 have aligned journals 30
and 3| formed therethrough. It is preferred to
have journal 30 larger than journal 31 for a
purpose to be explained hereinafter.
Passing through aligned journals 3E! and 3!
is shaft L5 having round bearing portion 36 co
operating with journal 30 and round bearing por
tion 31 cooperating with journal 3!. Between
bearing portions 36 and 31, shaft 35 is shaped
to a non-circular section and, in its simplest form
as shown here, may be shaped as squared’shaft
section 38. Loosely mounted 'upon' square shaft
portion 38 but rotatably locked thereto are a
pair of discs 40 and 4|. Both of these discs are
similar in construction and have relatively mas

portions 44. Hub 43 is, apertured at 45 so that
the discs may clear square shaft 38 while tilting
back and forth, In order to rotatably lock the
discs on square shaft portion 38, locking member
46 maybe set in at the center of each disc. Lock
for the manufacture thereof are comparatively
small and resulting articles possess a desirable
appearance and may be maintained clean in
simple and effective ways.
The invention in general contemplates the use
of a pair of discs tilted with respect to each
other. The tilting is such that a region of wide
disc separation provides a feeding region while a
region of minimum disc separation provides an 40 ing member 46 consists of a thin disc having

In order that the invention may be more fully
understood, reference will now be made to the

that the tilting action of disc 40 or 4| is around
the inner edge of disc 46. Disc 46 may be secured
to discs 4|] and M in any suitable manner as by
