PROVISIONAL SPECIFICATION.
Apparatus for Bruising and Disintegrating Bread Crust, Meat, and
other Viands.
I, PAUL LOUIS FRANÇOIS HIPPOLYTE CHAUSSINAND, of Saint-Dizier, France,
Doctor of Medicine, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for bruising and disintegrating articles of
food such as bread crust, meat or other viands. It consists of two parallel rollers
mounted in a suitable frame the bearings of the lower roller resting on springs, so
that it can be depressed to allow a slice to be operated on to be introduced between
the rollers.
These have projecting rings, the rings of the one roller projecting between the
rings of the other with or without lateral spaces between each two adjoining rings,
the rings being of various shapes, with or without teeth or indentations upon them
and with or without circumferential groove or grooves for the flow of juice, accord-
ing to the nature of the food treated and the degree of bruising or disintegration
desired. In order to clear the material off the rollers, scrapers may project into the
intervals between the rings of teeth, and the pieces scraped off may be received
on a plate carried on the springs which support the lower roller. Also a cutting
blade may be arranged on the base to cut the viand into suitable slices for feeding
the rollers. The axis of each roller carries a button by which both can be simul-
taneously turned in opposite directions by the thumb and finger of each hand.
Sometimes the rollers are merely fluted the ridges of the one projecting into the
hollows of the other, and in this case one only of the rollers need be turned, the
flutes acting as gearing to drive the other.

Apparatus for Bruising and Disintegrating Bread Crust, Meat, and
other Viands.
I, PAUL LOUIS FRANÇOIS HIPPOLYTE CHAUSSINAND, of Saint-Dizier, France,
Doctor of Medicine, 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 :-
-
This invention relates to apparatus for bruising and disintegrating articles of

page_text: food, such a bread crust, meat or other viands, as I shall describe referring to the
accompanying drawings.
Figs. 1 and 2 are respectively a longitudinal and transverse sections of one form
of apparatus according to my invention AA are two parallel rollers made with
projecting rings, the rings of the one entering the spaces between the rings of the
other, so that a slice of food material passed between the rollers as they revolve
in opposite directions is cut and bruised. The rings are toothed in various ways
according as they have to act on various kinds of material, they may occupy the
whole width of the ring as shewn in Fig. 1 or only the edges of the ring as
shewn in Fig. 3, and these edge teeth may be separated by a central groove for flow
of juice, or the teeth may occupy the middle of the ring as in Fig. 4.
One of the rollers has its bearings on springs J allowing the rollers to separate
more or less as the slice of material operated on is thicker or thinner, or the rollers
may be separated by hand to introduce a slice.
Each roller has at one end a knob I by which it can be turned, so that the operator
using both hands can turn the rollers in opposite directions. B are comb scrapers
having fingers entering the spaces between the teeth for detaching the disintegrated
pieces C is a plate on which the slice can be fed to the rollers; this plate being
attached to the sliding frame of the moveable roller can move up and down with it.
E is a fixed blade by which the material can be sliced to a definite thickness, which
can be varied by fixing the blade E higher or lower on the frame For the plate C
lower or higher on the sliding frame D.
The disintegrated material falls on the table G which is carried on a plate H
attached to the sliding frame D. The table G may be dispensed with, in which case
the moveable roller can be lowered by pressing down the plate H.
The apparatus shewn in elevation and section in Fig. 5, which is specially suited
for breaking up crusts, has the rings so far separated that they do not cut the crust,
the teeth serving to advance the crust and pierce it. Instead of rollers of the kind
described they may be fluted as shewn in elevation and section in Fig. 6 the blades
being either toothed or not. As these blades gear with one another it is necessary.
to turn only one of the rollers.
The crust breaking apparatus may have feeding plates and receiving tables like
the other apparatus.
In the modified apparatus adapted for crust crushing as shewn in Figs. 7, 8 and 9
the spaces between the rings are wider than the rings themselves so that the effect is
rather to crush than to cut, the upper roller is the moveable one, being mounted
in the stirrup D which can slide in the frame F subject to the spring J urging it
towards the lower roller.
In order to introduce a crust, the rollers are separated as shewn in Fig. 9. The
stirrup D is attachd to a stem H having a head H¹ to which is jointed a hand
lever He having a back spring h to keep the lever normally upright as in Fig. 7.
On a bracket at the side of H2 is mounted a roller h³, which when He is turned
down as shewn in Fig. 9 bears on the top of the framing and so raises the stirrup D
and the upper roller. When the crust has been introduced the hand lever H2 is
turned up again and then the spring J presses the upper roller down.
Then on turning the roller to and fro by the handle I, the crust is thoroughly
bruised and broken.
If the spring J is not strong enough for a hard crust, it may be aided by pressing
down the head 3 of the lever H². In order to prevent the toothed rings of the one
roller bearing against the axis of the other, one of the rollers may have at each
end a disc a' which is not toothed.
Or the descent of the upper roller might be limited by screwing the stem H
more or less down into D, so that the head h¹ forms a stop when it comes to bear on
the frame.
It is not necessary that the rings of both rollers should be toothed, those of the
lower roller may be plain, and the rings themselves may be of triangular section
as in Fig. 5, the teeth in all cases being preferably like those of a saw directed so as

page_text: to draw in the material to be operated on, when the rotation is always in one
direction.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is: —
1. Apparatus for bruising and disintegrating articles of food consisting of a pair
of rollers pressed towards each other by springs and each having toothed rings pro-
jecting into the spaces between the rings of the other, substantially as described.
2. The construction of the toothed ring with teeth at each side and a central
groove for flow of juice substantially as described with reference to Fig. 3.
3. The modification of the apparatus referred to in Claim 1 to adapt it for crush-
ing crust, by making the rings of less width than the spaces between them, sub-
stantially as described with reference to Figs. 7, 8 and 9.
4. In combination with the rollers, comb scrapers for detaching disintegrated
pieces, substantially as described.
5. For separating the rollers in combination with the stirrup in which the upper
roller is mounted, a stem to which is hinged a hand lever provided with roller, con-
structed and operating substantially as described.
