I JAMES OSBORN SPONG of 226 High Holborn, Middlesex, Domestic Appliances
Manufacturer do hereby declare the nature of my said invention to be as follows :—
The object of my invention is to construct mincing or chopping machines that
1. The cutting blades shall have a speed greater than that of the propeller, or be
made to travel at the same speed.
2. The outlet or back plate be provided with an adjustable gate.
3. The machine be provided with a rack serving also as a bearer for the spindle
which carries the cutters.
According to my invention I fit the cutters and the propeller on separate spindles
and by means of gear wheels driven by a crank handle or otherwise I rotate them at
separate speeds, preferably driving the cutters faster than the propeller.
This is effected by making the propeller spindle hollow, and in passing the cutters
spindle through it and in which it forms a bearing in conjunction with a rack, the
bars of the rack being so arranged that the cutters in their rotation pass through
between them as well as being supported by them. The propeller spindle sits in a
bearing of the casing, and its outer end carries a spur wheel geared into by a pinion
receiving its motion from another wheel operated by a crank handle.
The cutters spindle on its outer end has a pinion mounted on it geared into by an
intermediate wheel taking its motion from the driver wheel.
The rack is fitted loosely in the casing within notches or other device to centralise it.

page_text: If the propeller and the cutters are to revolve at the same speed two of the gear
wheels can be pinned, and the crank handle shifted to the spindle of the cutters.
The outlet plate or disc, whether screwed on or slid into position on the barrel or
casing has a somewhat large opening over the face of which a plate can be set to
reduce the size of the opening, and so keep the meat or other material under operation
in check; thus the cutters act upon it a greater number of times to reduce the meat
to any degree of fineness according to the adjustment of the plate.
In the foregoing description the spindle of the cutters is referred to as passing
through the propeller's spindle but this order may be reversed if found necessary.

1, JAMES OSBORN SPONG of 226 High Holborn, Middlesex, Domestic Appliances
Manufacturer, 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 :-
The object of my invention is to construct mincing or chopping machines that:-
1. The cutting blades have a speed greater than that of the propeller, or are made
to travel at the same speed.
2. The outlet or back plate be provided with an adjustable gate.
3. The machine be provided with a rack serving also as a bearer for the spindle
which carries the cutters.
According to my invention I fit the cutters a, a, on one spindle b and drive them
through the pinions c, d, e, the propeller f, being on a separate spindle g and driven
by means of gear wheels c, h, i operated by crank handle, or otherwise.
The cutters a, a, are driven faster than the propeller as will be understood by the
diagram Figure 2.
This is effected by making the propeller spindle g hollow and in passing the cutters
spindle 6 through it and in which it forms a bearing in conjunction with a rack k (see
Figure 3) the bars 1, 1, of the rack k being so arranged that the cutters a, a, in their
rotation pass through between them.
The propeller spindle g sits in a bearing of the casing m (see Figure 1).
The rack is fitted loosely in the casing m within notches or other device to
centralise it.
If the propeller f and the cutters a, a, are to revolve at the same speed the two gear
wheels e, i, can be pinned and the crank handle shifted to the spindle 6 of the
cutters a. a. the pinion / being drawn forward on its pintle n to be out of gear or be
removed from the machine.
The cutters a, a, are arranged at different angles upon the spindle as seen at
Figure 4.
p is a pressure plate for forcing the chopped or minced meat out of the aperture in
the outside plate which plate may be slid into position on the barrel or casing m in
which it fits a somewhat large opening so that it can be set to reduce the size of the
opening and so keep the meat or other material under operation in check, thus the

page_text: cutters a, a, act upon
it a greater number of times to reduce the meat to any degree
of fineness according to the adjustment of the plate.
In the foregoing description the spindle of the cutters is referred to as passing
through the propellers spindle, but this order may be reversed if found necessary.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is―
1. The means or appliances for producing an uniform speed or different speeds to
the cutters and propeller of a mincing or chopping machino, also the method of fitting
and supporting the spindles thereof as hereinbefore described and substantially as
shown in the annexed drawings.
2. The employment in mincing and chopping machine of a removable rack (see
Figure 3) through which the cutters can pass and serve also as a support to the cutter
spindle as herein before described.
