We, CHARLES REINHARDT of Number 17 Lowgate in the Town of Kingston upon
Hull in the County of the same Town Pork Butcher and THOMAS ATKINSON of 47
Spipre Street in Kingston upon Hull aforesaid, Engineer do hereby declare the nature
of this invention to be as follows
:-
This invention relates to a machine for mincing meat, which is of the following
description. A revolving wooden block of cylindrical form is mounted in a framing
with its axis vertical and adjustable to a higher or lower position by means of screws.
In bearings in the upper part of the framing is mounted a horizontal shaft having
cranks linked to the ends of a bar that is guided to move to and fro horizontally above
the wooden block. This bar has an arm linked to a fixed pin, so that as the bar is
moved to and fro horizontally by its connection to the cranks it is also caused to rock
or turn partly round to and fro by the connection of its arm to the fixed pin. On the
bar are fixed parallel at adjustable distances apart several curved knives, the curved
edges of which, as the bar moves to and fro rocking, roll along the upper surface of
the wooden block, which, by means of gearing connecting it to the crankshaft, is
caused to turn slowly round as the crank shaft revolves. Meat placed on the upper
end of the block within a projecting hoop which encircles it, is thus cut in all directions
by the reciprocating rolling knives until it becomes finely minced. The knives are
made with notches to receive the bar, being thus fitted on the bar in such a manner
that they can readily be removed or replaced, and when in position on the bar with
distance pieces of tube or washers between them, they are clamped firmly thereon by
screwing up a nut on the bar. In order to bring the bar into such a position that the
knives can be taken off or put on it, the link jointed to the arm of the bar is tem-
porarily removed from the fixed pin to which it is usually pivotted, and pivotted on
another pin, the bar being thus turned sufficiently round to bring the knives to a
position clear above the wood block.

page_text: We, CHARLES REINHARDT of Number 17 Lowgate in the Town of Kingston upon
Hull in the County of the same Town Pork Butcher and THOMAS ATKINSON of 47
Spyvee Street in Kingston upon Hull aforesaid, Engineer 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 a machine for mincing meat which is of the following
description. A revolving wooden block of cylindrical form is mounted in a framing
with its axis vertical and adjustable to a higher or lower position by means of screws.
In bearings in the upper part of the framing is mounted a horizontal shaft having
cranks linked to the ends of a bar that is guided to move to and fro horizontally above
the wooden block. This bar has an arm linked to a fixed pin, so that as the bar is
moved to and fro horizontally by its connection to the cranks it is also caused to rock
or turn partly round to and fro by the connection of its arm to the fixed pin. On the
bar are fixed parallel at adjustable distances apart several curved knives, the curved
edges of which, as the bar moves to and fro rocking, roll along the upper surface of
the wooden block, which, by means of gearing connecting it to the crank shaft, is
caused to turn slowly round as the crank shaft revolves. Meat placed on the upper
end of the block within a projecting hoop which encircles it is thus cut in all directions
by the reciprocating rolling knives until it becomes finely minced. The knives are
made with notches to receive the bar, being thus fitted on the bar in such a manner
that they can readily be removed or replaced, and when in position on the bar with
distance pieces of tube or washers between them, they are clamped firmly thereon by
screwing up a nut on the bar. In order to bring the bar into such a position that the
knives can be taken off or put on it, the link jointed to the arm of the bar is tem-
porarily removed from the fixed pin to which it is usually pivotted, and pivotted on
another pin, the bar being thus turned sufficiently round to bring the knives to a
position clear above the wood block.
Fig. 1 of the accompanying drawings shews a plan of the above described mincing
machine. Fig. 2 is a vertical section on line X X Fig. 1 and Fig. 3 a side view.
The framing A carries a horizontal shaft B of square section on which are fitted a
number of knives CC, these being slid with slotted upper ends on to the shaft and
secured in position at suitable distances apart by loose distance pieces D, the shaft B
having a fixed collar B¹ at one end and a screw nut B2 on a threaded part at the
other end so that by screwing up the nut, the knives and distance pieces are all
clamped firmly together on the shaft. On loosing the nut the knives can be slid off
the shaft and varied both as to number and position.
The shaft B is carried in blocks E capable of sliding to and fro between guides A¹
on the framing and it is connected by rods F F to cranks on the shaft G, so that by
the rotation of this shaft a to and fro motion is imparted to the shaft B between its
guides. The shaft B also has a crank arm H fixed to its one end, to which is pivotted
a rod I connected with its other, forked, end to a stud J on the framing A. The

page_text: result of this arrangement is, that as the shaft B is moved backwards and forwards it
also receives a rocking motion through the arm H and connecting rod I which is con-
sequently imparted to the knives C. The edges of these knives which are formed as
an arc of a circle struck from the centre of the shaft rest upon a wooden block K
which is supported at its lower end upon a central pivot L to which a slow rotary
motion is imparted through a worm and worm wheel M and spur gearing N, so that
the block K is made to revolve slowly while the knives move backwards and forwards
upon the same with a combined rolling and sliding motion, whereby the meat placed
upon the block is effectually cut up or minced, as it is brought under the action of the
knives such mincing being effected practically without noise.
ee are spring buffers against which the sliding blocks strike at the end of each
stroke.
The top of the block is surrounded by a sheet metal guard O for confining the meat,
and a stationary oblique blade P carried by the framing is provided for turning over
the meat as the block K revolves.
The block K is supported in its upright position by means of antifriction rollers Q
carried by the framing, which run upon a sheet metal ring R on the block that can be
shifted up or down. The pivot of the block is supported upon a transverse bar S
sliding in slots in the framing and capable of being raised or lowered at each end by
screwed rods and nuts T, so that by this means the upper surface of the block can be
accurately adjusted in height relatively to the knives.
When it is desired to remove the knives for sharpening them or altering their
position the rod I is detached from the stud J and raised up to the stud J' whereby
the shaft B will be turned so as to raise the knives upward away from the block and
they can then consequently be readily removed as before described.
On each side of the block a table U U is provided from which the meat is fed on
to and removed from the block as required so as to prevent waste.
By the above described improved construction of mincing machines the operation of
mincing is effected almost silently, and owing to the edges of the knives working in
the manner described over a revolving wooden block, the meat is kept cooler and
in better condition than in other silent machines where the meat is operated upon
by revolving cutters in a metal bowl.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed we declare that what we claim is :-
1. In a machine for mincing meat the use of knives or cutters mounted upon a
shaft to which a combined rectilinear and rotary reciprocating motion is imparted,
whereby the curved edges of the knives are made to operate with a combined
rolling and sliding action upon a block or plate on which the meat is placed,
substantially as herein described.
2. In combination with the knives of a meat mincing machine arranged and
operating as set forth in the preceding claim, the use of a vertically adjustable
wooden block revolving on a vertical axis upon the upper surface of which the
knives operate substantially as herein described.
3. In a meat mincing machine, a shaft B carrying knives (and receiving a
combined rectilinear and rotary reciprocating motion from a crank shaft G and
crank arın H and rod I and operating in combination with a wooden block K
revolving on a vertical axis L carried by a bar S vertically adjustable by screwed
rods and nuts T, substantially as herein described.
