page_text: I, HEINRICH SPÜHL, of St Fiden, near St Gallen, Switzerland, 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 improvements relate to a machine for filling sausages, in such a manner that
the required amount of the filling material is placed in a measuring cylinder
measured by the latter and pressed from out this cylinder into the respective skin,
avoiding thereby any special weighing or subsequent filling of such sausages.
Referring to the accompanying drawings Fig. 1 is a side elevation. Fig. 2 &
front elevation. Fig. 3 a plan of the machine. Fig. 4 a vertical section on a
Jarger scale showing the inserting mechanism for the measuring cylinder a¹.
Figs 5 and 6 show the actuating mechanism for the measuring cylinder a¹ also on
an enlarged scale and Figs 7 and 8 a reserve cylinder at for the measuring
cylinder a¹, when the filling material is not to be measured.
a is a cylinder, in which a piston b is moved up and down by means of the
crank c', through mitre wheels b and c, rods 63 provided with a screw thread, and
the transverse bar 6*.
The weight p arranged on the. rods 6 serves to facilitate the descent of the
piston.
At the crank axle c' is arranged, loosely on its pivot a double pawl o³ which can
be made to gear into a ratchet wheel c³, secured to the axle, so that by forward or
backward turning of the crank c7 it may be engaged with the ratchet wheel. At
the bottom of the cylinder a is situated the small revolvable measuring cylinder a³,
in which by displacing a piston c, the volume can be increased or decreased at
pleasure. This cylinder a¹ is turned for about 90° by the lever ³ rod k with the
two friction rollers k' and 2 (Fig. 5) and cam g¹, and brought in connection with
the outlet a and the sausage pipe y (Fig. 2).
The insertion of the piston c in the measuring cylinder a is effected by the hand
wheel f. By turning the latter, the slide f¹ with friction roller f³ is displaced in
the standard f³ such displacement being marked by an indicator on a scale. The
scale is so arranged as to indicate parts by volume of the measuring cylinder a¹.
A further division of these parts is arranged at the hub of the hand wheel. f.

page_text: The cam g situated on the axle n acts on the rod f³ and limits the stroke of the
same according to the position of the roller f³. The rod f³ is in connection with
the hook lever f' which surrounds a pin on the piston rod c¹ and adjusts the latter
in the cylinder a¹.
On the shaft o of the hook lever f' is situated the lever h with a pawl h¹
gearing into the ratchet wheel h³ of the same axle. With this ratchet wheel h³ is
connected a tooth wheel, which gears into a tooth wheel on the axle of so as to
cause the connection with the rods b' and therefore the motion of the piston to
take place..
The proportion of this transmission gear is so calculated, that the downward
motion of the measuring piston c causes a corresponding motion of the pressing
piston b in the store cylinder a, in such a manner that the pressing piston 6 presses
in rather more filling material than the small piston c in the measuring cylinder,
allows place for the filling material in the measuring cylinder a is therefore
subjected to a certain pressure, so that the single sausages are filled with equally
pressed filling material, and a uniform weight of the same thereby obtained. To
prevent this repeated pressure from increasing, an elastic connection h³ is arranged
between the hook lever f' and lever h. When the difference of pressure in the
two cylinders a and a¹ becomes stronger than the spring pressure between the
parts h³, the spring is compressed and thereby a uniform pressure is produced.
The pawl serves the purpose of preventing the ratchet wheel h' from receding.
For allowing the pawls h¹ and h to be simultaneously and commodiously dis-
engaged, which must take place when the cylinder a is to be refilled two lever
arms and are arranged at the axle i, by the turning of which arms the
pawls h¹ and h are pressed out of the teeth.
After the piston in the measuring cylinder a has been brought to its right
position by the cam g and the filling material has been pressed in, the cam g¹
begins its action on the axle n, by shifting the rod k forward and turning by means
of lever the measuring cylinder a for about 90°, so that cylinder a communicates
with the opening a² and the sausage filling pipe y. The piston rod c¹ thereby
leaves the hook lever f* and arrives against the shoulder l, which is moved by the
cam g. The latter presses the piston c forward and brings the sausage material
into the filling pipe y and into the sausage skin, fastened thereto. To prevent the
piston c from receding, when the measuring cylinder a¹ is turned the piston rod c¹
is arrested by an elastic lever do the clamping cheek d' and the roller d, which
slides in the groove d and presses the clamping cheeks d' against the piston rod c¹.
The groove is so formed, that this stop again released at the end of its travel so
that the piston rod c' can be moved again as above described by the shoulder
and cam g. As a guide for the support of the rollers and the arm ³ is
arranged (Fig. 5) which moves in the rails . This rod carries a spring device *7*
which is brought to tension, when recedes, and transfers the force to the
piston c, when the latter is advanced, which facilitates considerably the advance of
the piston
While the piston c is pushed forward, the cam g causes the rod f³ to move
downward, therefore the hook lever ht to rise. The cam g¹ then comes into action
and presses back the rod k and thereby turning the measuring cylinder a' again
into the position shown in Fig. 4, so that the roller of the piston rod c¹ enters the
raised hook of the lever h. The cam disc g moves the rod f³ again upwards,
draws the hook lever h* down into its original position (Fig. 4). The working of
the various mechanism is then repeated.
The revolution of the cam axle n is effected by crank m through the tooth
wheels 8 and 8¹. Each sausage filling requires a revolution of the axle n for
executing the above described revolutions.
•
The measuring cylinder a allows of being easily removed for the purpose of
cleansing, by screwing off the bow W.
For stuffing sausages which are not required to be of certain weight the
revoluble measuring cylinder a is replaced by the stationary filling or stuffing

page_text: cylinder a shown in Fige 7 and 8, through the rounded opening of which a direct
connection of the store, cylinder a with the sausage pipe y is produced.
The descent of the piston 6 may also be effected as explained above by the
crank m if the shaft n is connected by tooth wheels with the shaft c.
In order to allow atmospheric air to penetrate under the piston 6 when the same
is raised a tube 61 arranged round the piston rod is connected above with the
transverse bar 6 and is provided below with a flange b' fitted with pins which
penetrate into tapered holes in the piston b. When the piston b is raised, the
tube b' first rises with the transverse bar b' up to the nut 6 of the piston rod so
that the lower flange 65 is lifted away from the piston and atmospheric air thereby
allowed to enter at the tapered holes in the latter.
For economy of space the table vis adapted to be folded.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:-
In a sausage stuffing machine;
1. The combination of a store cylinder. a with a rotary measuring cylinder a¹
containing a pressing piston e inserted therein for the purpose of taking from out
of the store cylinder a a certain measured volume of the material and of pressing
the same into the filling space or into the skin fastened thereto.
2. With the combination referred to in Claim 1 the device for securing.the piston
on the cylinder a' during the movement of the latter, consisting of elastic lever d³
with clamping cheeks d³, and groove d.
3. With the combination referred to in Claim 1 the device for actuating the
measuring piston c consisting of the hook lover f' slide f, the adjustable rod fi and
cam g in connection with the device h h¹ h³ h³ for the purpose of providing the
stroke of the pressing piston b with an elastic pressure.
4. With the combination referred to in Claim 1, the device consisting of. the
