IN APPARATUS FOR MINCING MEAT AND OTHER SUBSTANCES." A communication
from Carl Hammer, senior, and Heinrich Perschmann, both of Brunswick, in the
Empire of Germany.
This Invention consists in imparting to the chopping block a kind of planetary
motion, that is to say, a rotary motion round an axis, which itself revolves on
another axis. This may be effected by mounting the chopping block on a base plate
resting on two toothed horizontal discs or spur wheels supported by rollers, the
upper of the said discs turning loose on the nave of the lower disc, which revolves
with a different speed and carries in its nave a pin projecting upward into the
upper disc, thereby causing the latter to revolve on the axis of the lower disc.
The upper wheel (having a greater speed than the lower wheel) upon which the
chopping block with its base plate rests, causes the same to revolve on the
excentric pin.
The motion of the two wheels is preferably obtained by means of two pinions of
unequal diameter mounted on the same shaft, which is driven by a worm and
worm wheel. Or the upper wheel may be provided with a downward projecting
internally toothed flange, between which and the externally toothed lower wheel
a driving pinion is placed, which gears at the same time into the flange of the
upper wheel and the circumference of the lower wheel.

"IMPROVEMENTS
IN APPARATUS FOR MINCING MEAT AND OTHER SUBSTANCES." A communication
from Carl Hammer, senior, and Heinrich Perschmann, both of Brunswick, in the
Empire of Germany.
These improvements relate to a peculiar arrangement destined for imparting a
concentrical and at the same time an excentrical revolving motion to the chopping
block of the apparatus.
The annexed Drawing represents an apparatus embodying these improvements.
Fig. 1 is partly a vertical section and partly a side elevation, and
Fig. 2, a top view of the apparatus, the chopping block being taken off in order
to allow an easier explanation of the arrangement.
The whole apparatus is mounted on a frame B placed upon the foundation A.
It is intended to be driven by machinery, the motive power being transmitted to
the main shaft C by means of a belt. On this shaft are placed two pulleys, one of
which D is destined to drive the shaft C¹, and thereby impart a rocking motion
to the chopping knife G by means of the crank a and connecting rod b, while the
other pulley E transmits motion to the lower shaft c The vertical spindle d
receives its motion from the latter by means of the worm e and worm wheel f, and
carries at its upper end two pinions of different diameters g and g¹. The larger
one of them gears with the upper wheel H, and the smaller one with the lower
wheel I, which is a little larger than the upper wheel H, which turns loosely upon
the nave of the latter. The result of this arrangement is that at every revolution
of the spindle d the wheel H turns a little faster than the wheel I.
The chopping block K is provided at its bottom with a circular metallic plate h
embracing the lower edge of the block, which plate rests directly upon the wheel H.
The nave i of the wheel I penetrates the central hole of the wheel H, and carries
at its upper face a pink placed excentrically in relation to the common axis of
rotation L of the wheels Ĥ and I. The weight of the latter and the block K,
together with the chopping knife G, rests upon the four supports provided with
rollers on which the whole appliance rolls.
If now the apparatus be put into action, the wheels H and I will turn forward
at speeds corresponding to the different numbers of teeth of the wheels put in gear.
The upper wheel H revolving round the nave i takes along with it by friction the
chopping block K, which turns round the pin k. As the wheel I is put into
rotation at the same time, the pin k or the centre of revolution of the block
performs a circular motion, thus causing the block to slide partially upon the
wheel H while turning round the pin k. The result is that during one complete
revolution of the wheel I the block K will at successive moments occupy different
excentrical positions in relation to the centre L of revolution of the wheels H
and I.
Figs. 3 and 4 show a modification of the arrangement just described.
In this case the upper wheel H, on which the block K rests, is provided with
internal teeth and is larger than the lower wheel I, which is externally toothed.
Both these wheels are moved by one pinion g placed between the internal and
external teeth of the wheels. The spindle d receives its motion in the same way
as above described.
It will be understood that in this case the wheels H and I do not revolve in the
same direction as in the arrangement shown by Figs. 1 and 2, but the one moves
in opposite direction to the other.

page_text: CLAIM.
In an apparatus for mincing meat and other substances, the above described
appliances for imparting a kind of planetary motion to the chopping block K, these
appliances consisting substantially in the one case (Figs. 1 and 2) of the two pinions
g and g', and the two independent wheels H and I, the latter having a nave i
which penetrates the centre of the former, and is provided with a pink placed
excentrically to the axis L and forming the centre of revolution of the chopping
block; and in the other case (Figs. 3 and 4) of only one pinion g placed between
the two wheels H and I, the former of which is toothed internally and the latter
externally.
In witness whereof, I, the said Charles Max Sombart, have hereunto set my
hand and seal, this Eighth day of April, 1882.
