of Suney
"AN IMPROVED CHOPPING MACHINE"
This Invention relates to certain improvements in the construction of machines
for chopping meat and other substances, such machines being combined directly
with the engines fiom which the motive power is obtained, whereby many of the
disadvantages which attach to maclunes to the like purpose as previously con-
structed are avoided
In accordance with this Invention the engine by which the knives are worked 18
placed immediately above the block of the machine upon which the operation of
cutting is effected, and the knife cannage is attached to the lower end of the piston
rod of the engine, and by which it is alternately raised and depressed, the action of
the piston 1od being produced and regulated in the ordinary way in connection with
a fly wheel and other necessary mechanism as well understood
The knife caillage
with the ends of the cross bar at the lower end of the piston rod works in slides by
which the motion thereof is regulated
By means of the above-described aangements many of the pieces of mechanism
which are necessary in chopping machines as ordinarily constructed, such as crank
connecting rods for transmitting motion from the engine to the knives, the working
bearings for the knife carnage, band, wheel, and straps, and other contivances
usually employed, are dispensed with, the result being that the machine works
much more effectually and regularly, and in a comparatively noiseless manner
The requisite 1otary motion of the block is obtained by the action of a vertical
rod which is connected with and actuated by the revolution of the crank shaft of
the fly wheel The said rod is provided at its lower extremity with a pawl acting
upon a ratchet arrangement, motion being given to a toothed wheel which gears
into the teeth of a worm wheel placed beneath and attached to the block The said
mechanism for actuating the block is attached to the block carriage so that the

wearing away of the surface thereof by use A bracket is also fastened on the
block carriages for steadying the same, and thus preventing the inconvenience of
wedging the same as ordinarily practised.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Henry John Hurwood in the Great Seal Patent Office on the
8th August 1877.
HENRY JOHN HURWOOD, of Lebanon Street, Walworth Common, in the County
of Surrey. "AN IMPROVED CHOPPING MACHINE"
My said Invention relates to certain improvements in the construction of
machines for chopping meat and other substances, such machines being combined
directly with the engines from which the motive power is obtained, whereby many
of the disadvantages which attach to machines for the like purpose as previously
constructed are avoided
In accordance with this Invention, the engine by which the knives are worked is
placed unmediately above the block of the machine upon which the operation of
cutting is effected, and the knife carriage is attached to the lower end of the piston
rod of the engine, and by which it is alternately raised and depressed, the action of
the piston rod being produced and regulated in the ordinary way in connection
with a fly wheel and other necessary mechanism, as well understood The knife
carriage, with the ends of the cross bai at the lower end of the piston rod, works in
slides by which the motion thereof is regulated
By means of the above described arrangements, many of the pieces of mechanism
which are necessary in chopping machines as oidinarily constructed, such as ciank
connecting rods for transmitting motion from the engine to the knives, the working
bearings for the knife carriage, band wheel, and straps, and other contrivances
usually employed, are dispensed with, the result being that the machine works much
more effectually and regularly, and in a comparatively noiseless manner
The requisite 1otary motion of the block is obtained by the action of a vertical
1od which is connected with and actuated by the revolution of the crank shaft of
the fly wheel The said 1od is provided at its lower extremity with a pawl acting
upon a ratchet arrangement, motion being given to a toothed wheel which gears
into the teeth of a worm wheel placed beneath and attached to the block The said
mechanism for actuating the block is attached to the block cari lage, so that the saine
1s always ready for action when the block is raised to compensate for the wearing
away of the surface thereof by use A blacket is also fastened on the block
callages for steadying the same, and thus preventing the inconvenience of wedging
the same as ordinarily practised
Having thus declared and ascertained the nature of my said Invention, and in
what manner the same is to be performed, I would observe in conclusion, that
what I consider novel and original, and therefore claim as constituting the
Invention secured to me by the said hei cm-before in part recited Letters Patent 15,
the combination and arrangement of parts and mechanism, substantially as and for
the purposes herein-before set forth and described, or any meie modifications
thereof.
In witness whereof, I, the said Henry John Hurwood, have hereunto set my
hand and seal, this Seventh day of August, in the year of our Loid One
thousand eight hundred and seventy-seven.
