IMPROVEMENTS IN THE CONSTRUCTION OF MACHINES FOR CUTTING OR MINCING
MEAT, VEGETABLES, AND OTHER LIKE SUBSTANCES, WHICH IMPROVEMENTS ARE ALSO
APPLICABLE TO THE MANUFACTURE OF OTHER MACHINES."
My Invention relates to improvements in the construction of machines for cutting
sausage meat, mince meat, and cutting or mincing vegetables or fruit, and for other
like purposes, and is designed to simplify and cheapen the manufacture of these
machines and other machines of a similar character.
Mincing machines as ordinarily constructed have a case or box fitted with a series
of fixed blades or knives in combination with a rotating propellor, and the said box
has a cover which permits access to the interior of the machine. In these machines
as heretofore constructed the said cover has in most cases been hinged to the box,
and has had to be fitted to its place by the aid of a file and other tools, involving
the employinent of skilled labor. But according to my Invention I so modify the
construction of the cover and method of its attachment that it may be fitted by boys
or other persons not possessing any mechanical skill.
For this purpose I cast the lower half or part of the box with inclined or dovetail
flanges at the edges upon which the cover fits, and extending from end to end of
the same.
The cover bas similarly formed grooves or channels extending from end
to end of the cover, and so formed that when these recessed or grooved edges of the

page_text: cover are fitted upon the inclined or dovetailed edges of the box, the said cover will
slide freely upon the same into its place, and will be held securely on the box, and
will prevent any escape of the meat through the joint.
The box and cover are cast with the said grooved and dovetailed or inclined
surfaces on them, and the said surfaces are made to fit each other with the necessary
accuracy by grinding them on emery wheels or other suitable grinding wheels; and
it will be obvious that this work may be very cheaply performed.
Another part of my Invention relates to the construction of the rotating pro-
pellors of these machines. Heretofore these propellors have been formed of separate
blades or pieces with differently bevilled shapes, and each one fitted at different
angles of inclination upon a shaft or spindle passing longitudinally through the said
box; this method of construction is very inconvenient in many respects, as it neces-
sitates the keeping in stock of great numbers of these separate pieces, and the
absence of any of them would cause a delay in the fitting up of the machine; and
moreover great care must be observed in fitting these pieces on their shaft to ensure
each piece being set in its proper position. According to my Invention these diffi-
culties are obviated by casting the said propeller and the shaft or spindle in one
piece, so that the work of fitting the said propellor blades upon their shaft is
obviated, and the time and skill heretofore expended upon this part of the machine
are rendered unnecessary.
The box and the said cutters are galvanized or coated-with tin or other metal.
The end of the said shaft is turned to fit the bearing in the neck of the box as
usual, and the projecting end of the said shaft is provided with the ordinary handle.
The machine also has the usual feed hopper and tube or spout for the discharge
of the minced material, and is provided with the usual means for securing it upon a
table, bench, or other support.
It will be obvious that the above described method of fitting a cover upon a box
and of forming a propellor or series of projections or series of knives upon a shaft
or spindle may be embodied in machines for other purposes than those above
specified.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Kent in the Great Seal Patent Office on the 11th June 1877.

"IMPROVEMENTS IN THE CONSTRUCTION OF MACHINES FOR CUTTING OR MINCING
MEAT, VEGETABLES, AND OTHER LIKE SUBSTANCES, WHICH IMPROVEMENTS ARE ALSO
APPLICABLE TO THE MANUFACTURE OF OTHER MACHINES."
My Invention relates to improvements in the construction of machines for cutting
sausage meat or mince meat, aid cutting or mincing vegetables or fruit, and for
other like purposes, and is designed to simplify and cheapen the manufacture of
these machines and other machines of a similar character.
Mincing machines as ordinarily constructed have a case or box fitted with a series
of fixed blades or knives in combination with a rotating propeller, and the said box
has a cover which permits access to the interior of the machine. In these machines
as heretofore constructed the said cover has usually been hinged to the box, and
has had to be fitted to its place by the aid of a file and other tools in such a
manner as to necessitate the employment of skilled labor for this purpose. But
according to my Invention I so modify the construction of the cover and method of
its attachment that it may be fitted by boys or other persons not possessing any
mechanical skill.
My Invention relates partly to novel means for ensuring the tight and secure
attachment of the cover to the box, and partly to a peculiar manner of constructing
the propellers for these machines.

page_text: My Invention is carried into practise in the manner shewn in the accompanying
Drawing, in which,―
Figure 1 is a side elevation of a machine constructed according to the said Inven-
tion; Figure 2 is an end elevation of the same.
Figure 3 shews the propeller and its shaft detached or separate from the said
machine.
Similar letters indicate the same parts throughout the Drawing.
A is the case or box, which consists of the lower part A¹ and the upperpar tor
cover A. I cast the lower half or part A¹ of the box with bevelled or dovetail
flanges a on the edges, upon which the cover A³ fits, and these flanges extend from
end to end of the case or box, as shown. The cover A² also has flanges a¹, in which
are formed grooves or channels of a sectional shape corresponding with that of the
flanges a, and extending from end to end of the cover A. These parts are so formed
that when the end of the cover is placed with its recessed or grooved edges or
flanges a¹ upon the end of the bevelled or dovetailed edges or flanges a of the box,
the said cover will slide freely endwise upon the box, and by so sliding it may be
adjusted into its place; it will then be held securely on the box by the said flanges
and recesses, its end a being covered by the rim or flange a³ on the box. The said
flanges a, a, also serve effectually to prevent any escape of the meat or other
material through the joint or between the two parts A' and A² of the box.
The box A¹ and cover A² are cast with the said grooved and dovetailed or bevelled
surfaces on them, and the said surfaces are or may be made to fit each other
with the necessary accuracy by grinding them on emery wheels or other suitable
grinding apparatus; and it will be obvious that this work may be very cheaply
performed.
Heretofore the propellers of these machines have consisted of a series of blades or
pieces formed separately and of different shapes, and these pieces were fitted at
different angles of inclination upon a shaft or spindle passing longitudinally through
the said box; this method of construction is very inconvenient in many respects,
as it necessitates the keeping in stock of great numbers of these separate pieces of
the propeller, and the absence of any of them would cause a delay in the fitting up
of any machine; and moreover great care must be observed in fitting or adjusting
these pieces on their shaft to ensure each piece being set in its proper position. But
by my Invention these difficulties are obviated by casting the propeller blades b and
their shaft or spindle c in one piece, so that the work of fitting the said propellor
blades or pieces upon their shaft is obviated, and the time and skilled labor here-
tofore expended upon this part of the machine are rendered unnecessary, and the
cost of the manufacture of the said machines is reduced accordingly.
I prefer that the box A¹, cover A, and the propeller should be galvanized or
coated with tin or other metal.
The end of the said shaft is turned to fit the bearing in the neck of the box as
usual, and the projecting end of the said shaft is provided with the ordinary handle,
as shewn.
The machine also has the usual feed hopper and tube or spout for the discharge
of the minced material, and is provided with the ordinary means for securing it
upon a table, bench, or other support.
It will be obvious that the above described method of fitting a cover upon a box
and of forming a propeller or series of projections or blades upon a shaft or spindle
may be embodied in inachines for other purposes than those above specified.
Having thus fully described my said Invention and the manner of performing the
same, I wish it understood that I claim,―
First. The flanges and grooves or channels in the box and cover, formed and fitted
together as above described and for the purpose specified.
•
Second. The peculiar method of constructing a series of projections, blades, or
pieces upon the shafts or spindles of mincing and other machines, as above set
forth,

page_text: Third. A cutting or mincing machine embodying in its construction the novel
method of fitting and securing the cover upon its box or case, and the novel manu-
facture of its propeller, as shewn in the accompanying Drawing and as above
specified.
In witness whereof, I, the said George Kent, have hereunto set my hand and
seal, this Ninth day of June, in the year of our Lord One thousand cight
hundred and seventy-seven.
