Improvements in Choppers or Mincers.
I JOSEPHI EMILE AUZAT of Clermont Ferrand, in the Republic of France
Draughtsman, do hereby declare the nature of this invention to be as follows:-
This invention for improvements in choppers or mincers has for its object to
provide apparatus for mincing meat and for similar purposes which is automatically
sharpened and cleaned and consists in mounting a series of circular blades or discs
loosely on shouldered sleeves threaded on a square spindle fixed in a frame
provided with a suitable handle, in pivotting to the said frame a grinding frame
provided with a spindle on which are mounted loosely a series of grinding stones or
discs having chamfered edges to receive the peripheries of the blades and capable
of being forced against the said blades and retained in this position, and in providing
a cleaner or bent plate having slots through which the said blades pass and which
is fixed to the sleeves carrying the blades. A. scraper is fixed on to the end of the
grinding frame. It will be readily understood that in use the chopper or mincer is
rolled over the article to be minced backwards and forwards.

COMPLETE SPECIFICATION.
Improvements in Choppers or Mincers.
I JOSEPH EMILE AUZAT of Clermont Ferrand, in the Republic of France,
Draughtsman, 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 for improvements in choppers or mincers has for its object to
provide apparatus for mincing meat and for similar purposes which is automatically
sharpened and cleaned and consists in mounting a series of circular blades or discs
loosely on shouldered sleeves threaded on a square spindle fixed in a frame provided
with a suitable handle, in pivotting to the said frame a grinding frame provided
with a spindle on which are mounted loosely a series of grinding stones or discs
having chamfered edges to receive the peripheries of the blades and capable of
being forced against the said blades and retained in this position, and in providing
a cleaner or bent plate having slots through which the said blades pass and which
is fixed to the sleeves carrying the blades. A scraper is fixed on to the end of the
grinding frame. It will be readily understood that in use the chopper or mincer
is rolled over the article to be minced backwards and forwards.
In the accompanying sheet of illustrative drawings,
Fig. 1 is a side elevation of a chopper constructed according to this invention and
Fig. 2 is a section on the line E F Fig. 1 of the same.
Fig. 3 is a plan of the frame and
Fig. 4 is a plan of the scraper.
The two cheeks a, a' of the frame A support between them the sleeves D carrying
he discs or blades L and mounted upon a square rod G passing through square
oles qat the front end of the cheeks a, a' and secured by a hand nut g. The
lades C are circular and sharpened upon their peripheries and rotate upon the
osses d of the sleeves D, the bosses being of the same length as the thickness of
he blades so as to prevent all end movement. A cleaner i is rivetted to each
[Price 6d.1

page_text: sleeve D and between the blades L to clean them from any adhering material that
is being operated upon. The handle B is secured to the frame A. by means of the
rod H taking into the hole in the frame A.
Each cheek of the frame A has secured to it by a screw e taking into a tappet
hole pa bracket I which pivots on the screw. The brackets I are fixed in the
required position by thumb screws passing through the curved slots in the
brackets and screwing into tappet holes s in the frame A. The grinding stone is
supported and rotates on a rod G mounted in the brackets I and secured by the
nut k. It is grooved as shown so that the edges of the blades enter the grooves and
are acted upon on both sides. The grindstone when desired to sharpen the blades
is lowered on to them and fixed by screws f. The stone may be replaced by a
series of chamfered discs. The scraper J is secured to the outer ends of the
brackets I by means of rivets passing through the ears r on the scraper and through
the brackets and serves to gather together the material being chopped which
spreads under the action of the discs.
The chopper requires only to be rotated over the material being operated upon
and acts noiselessly and rapidly without causing any fatigue.
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 chopper or mincer consisting of a number of circular blades or discs mounted
so as to rotate independently of one another about a fixed shaft provided with
means for operating it substantially as described.
2. A chopper or mincer consisting of a number of circular blades or discs mounted
loosely on bosses of separate sleeves fixed on a shaft secured to an operating handle
substantially as described.
3. A chopper consisting of a number of parallel circular blades or dises mounted
so as to rotate about a fixed shaft and provided with cleaners arranged between
the blades and secured to the sleeves fixed on the said shaft substantially as
described.
4. The combination with a chopper consisting of a number of parallel circular
blades or discs mounted on a fixed shaft, of a grinding apparatus for sharpening the
blades and consisting of a grinding stone carried on a moveable frame capable of
being fixed either with the stone in contact with the blades or raised therefrom
substantially as described.
5. The combination with a chopper consisting of a number of parallel circular
blades or discs mounted on a fixed shaft, of a scraper for gathering together the
material being chopped substantially as described.
6. The improvements in choppers or mincers substantially as described with
reference to the drawings.
