COMPLETE SPECIFICATION.
Improvements in and connected with Sausage Machines.
I, WILHELM VON DER NAHMER, of Remscheid, near Solingen, in the Province of
the Rhine, German Empire, 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:-
-
+
This invention relates to sausage-machines capable of use in large sausage works.
or for domestic purposes, and has for its object various improvements. more
especially as regards increasing the safety in working, by affording the possibility:
of interrupting the operation of the machine at any moment, and further increas--
ing also the efficiency of the machines of this description.
The improved sausage machine forming the subject of this invention and here-
inafter more fully described is based more especially, upon the employment of a
worm as driving-gear.
The said worm is driven by a toothed wheel of large diameter which may he
driven by hand or power and upon the shaft of the said toothed wheel, is a small.
cog wheel which gears with a toothed rack, in such manner, that when the said
rack engages with the small toothed wheel, the filling piston is lifted, or is caused.
to ascend, and overcomes the action or influence of the disconnecting springs or
weights, these springs or weights being capable in the manner hereinafter described
of bringing the said worm (guided or mounted in a suitable sledge); out of gear;
with the mechanism actuating the movement of the filling piston, so that upon
the release of the locking mechanism, which holds the worm (which locking.
mechanism may be a bolt or the like) the said worm is either by hand or auto-,
matically by suitable gear disconnected and brought out of operation in the
manner hereinafter described.
I have shown for purposes of illustration my invention in the accompanying
drawing, in which:
Figure 1 is a side or end-view in elevation. "
Figure 2 is a front view,
Figure 3 a plan of my improved sausage machine, &
Figure 4 an enlarged view of the sledge and worm when placed out of gear by.
the action of the springs or other suitable mechanism.

"
I will proceed to describe my improvements with reference to the accompanying
drawings.
.
In the drawing: the actuation of the filling piston k is effected by the revolution
of a worm d said: worm engaging with the large toothed wheel e. The small
toothed wheel engages with the rack b, the said rack causing the filling piston -
either to ascend or descend within the cylinder according to the direction in which
the fly-wheel rotates.
The worm shaft a is journaled in a slide or sledge o, said slide being arranged.
to move in suitable guides.
:

It will thus be clear, that the said slide o and the worm d of the same, can
radially approach or recede from the fly-wheel e, i.e, the teeth of the worm may

page_text: either be brought into engagement with the teeth of the fly-wheel, or, when the
worm recedes from the fly-wheel by means of the action of the before-said slide o,
it is clear, that the worm would be brought out of gear with the said fly-wheel.
The beforesaid moving away or receding of the worm from the fly-wheel, or, in
other words, the putting out of gear of the worm is, as indicated, effected in the
following manner, (as soon as the piston has finished its stroke):
The slide or sledge is held by the bolt or the like, n in such position,
that the worm & can come into gear with the teeth of the fly-wheel e.
The said bolt or locking mechanism n is provided with a suitable spring, said
spring keeping the said bolt in proper position and preventing the same from
being accidentally released by the action of the machine.
I have hereinbefore indicated in the preamble of the specification, that I bring
the worm out of gear with the teeth of the fly-wheel by the employment of springs
which are free to act as soon as the before mentioned bolt n is released. These
springs are shown in the drawing in Figures 2 & 4 and are attached or fixed
to the before mentioned slide o.
When the worm is in engagement with the fly-wheel, the said springs are in
tension but as soon as the pin or stud i (Figures 2 & 4) strikes against and actuates
the nose m of the bolt or locking mechanism the said bolt is released from the
slide, or sledge o, so that the sledge is immediately brought out of gear and raised
by the action of the said springs plp³, whereby, as is clear, the worm must be
brought out of gear with the fly-wheel and the working of the machine, at once
interrupted and stopped.
The before mentioned pin or stud i is so arranged that the same comes in
contact, as indicated, with the nose or projections m of the slide as soon as the
filling piston has reached its highest point.
The herein before mentioned object of my invention, namely to stop the working
mechanism of the machine as soon as the piston has thus reached its highest
point, is therefore attained and moreover by means of my improved mechanism
it is possible to stop the working parts of the machine at any point, by with-
drawing the beforesaid locking part n. This arrangement would be of especial
advantage when any irregularity occurs in the proper working of the machine
or any blocking of the material in the filling cylinder.
More especially when machines of this description are driven by power it may
easily happen, that when the piston reaches its highest point, the pressure may
cause parts of the machine to snap, break or burst; this risk is, however, entirely
avoided by my improved mechanism, which, as shown not only automatically puts
the machine out of gear when the piston has reached its highest point, but which
furthermore enables, as hereinbefore indicated, the working of the machine to
be interrupted at any moment.
Proceeding to describe the parts of my improved machine I have in conclusion
to remark, that as soon as the same has been automatically placed out of gear by
the piston having reached its highest point, the empty cylinder must of course be
refilled.
For this purpose the top cylinder cover is removed in known manner,
the fly-
wheel e (now out of gear with the worm d) is turned by means of the crank handle,
so that the piston descends to its lowest position in the cylinder, after which the
cylinder is again filled with sausage meat as required.
The cylinder cover is now closed and the worm d again brought into engage-
ment with the fly-wheel e. This is effected in a simple manner by means of a
hand-lever r, the eccentrics of which, when pressed down, causes the sledge or
slide o to overcome the tension of the springs p¹ and p² and also causes the said
worm d of the said slide to descend into its proper position.
When my improved machine above described is driven by power, (for instance
from the belt pulley c, as shown in Figure 1), it may be necessary to have at hand
means whereby the machine may be placed out of gear at any optional moment.

page_text: This, as hereinbefore indicated, is easily effected by withdrawing by hand, the
bolt or locking mechanism m.
In conclusion my improved machine is simple in construction, easily operated,
has no complicated gearing and possesses the herein before indicated advantage
of considerably increased safety by the automatic release of the working parts in
the manner shown.
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:-
A sausage-machine characterised by the arrangement of a worm, actuated by
hand or power, said worm-wheel having springs adapted to bring the slide or
sledge out of gear with the parts actuating the filling piston of the cylinder, in
such manner, that upon the release of the bolt or locking mechanism by hand or
otherwise, the movement of the filling piston is immediately interrupted and
stopped, substantially as described.
