COMPLETE SPECIFICATION.
Hydraulic Stuffing-machine for Sausage-skins.
I, WILHELM VON DER NAHMER, of Remscheid, in the Kingdom of Prussia,
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:-
in the sausage skin stuffing machines known up to now, the piston pressing the
chopped meat through a nozzle into the skin is driven by means of cog-wheels,
racks and similar parts forming in their entirety a rather complicated mechanism.
The purpose of my present invention is to simplify the machines in question by the
use of hydraulic pressure, as will be more fully described hereinafter.
C
Referring to the accompanying drawing, a designates the stuffing-cylinder
arranged above the pressure-cylinder b. The latter contains the plunger c which
at its upper extremity increases in diameter, and forms the piston d. Plunger c is
tightened in the usual manner by a collar consisting of leather or another suitable
material. Cylinder 6 is connected by means of the force-pipe e with a double-
acting pump e, the suction-pipe e² of which extends down into the basin f
The pump may be operated either by hand-crank or by pulley, according to the
size of the machine. The movements of the shaft carrying the hand-crank, or
pulley respectively, are transmitted to the pump by an eccentric n, and an eccentric
rod n. The water sucked into the pump is taken out of basin f, and is pressed by
the pump into cylinder b, so as to cause the plunger-piston cd to rise.
chopped meat is pressed under the action of piston d through nozzle g into the skin,
the latter having been drawn beforehand over said nozzle, and having been
fastened thereon.
The
Pumpe is operated as long as requisite for filling the sausage-skin completely.
The delivery of the chopped meat will cease as soon as the pump is stopped.
In order to allow in a convenient manner a control concerning the quantity of
meat contained within cylinder a, there is connected with the piston of the latter a
rod h, the lower end of which is bent. Said rod moves upward together with
piston d. When piston d is about to move through the last, or uppermost, portion
of its path, said bent end of rod h strikes against an arm m attached to a vertical
rod m; this rod is secured to the plug of a cock o adapted to let escape the
pressure-water contained within cylinder b. Said cock will be opened as soon as
piston d has finished its path, i.e. all the meat has left the cylinder a. It will be
indicated, thus, by the opening of cock o, and by the interruption of the pressure
caused thereby, that cylinder b has been emptied. The pistons c d will then sink
down by their own weight. By that arrangement, there is, moreover, the piston d
prevented from pushing upon the cover of cylinder a.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a stuffing-machine for sausage-skins, the combination with a stuffing-
cylinder, of a hydraulic cylinder adapted to operate the piston of said stuffing-
cylinder, substantially and for the purpose as described.
2. In a stuffing-machine for sausage-skins, the combination with the piston of the
stuffing-cylinder, of a hydraulic cylinder, the plunger of which is connected with
said piston, substantially and for the purpose as described.
3. In a stuffing-machine for sausage-skins, the combination with the stuffing-
cylinder proper and with the piston of the same, of a hydraulic cylinder, the

page_text: plunger of which is connected with said piston, the latter having a rod adapted to
open the discharge-cock of the hydraulic cylinder, substantially and for the purpose
as described.
4. In a stuffing-machine for sausage-skins, the combination with the stuffing-
cylinder proper and with the piston of the same, of a hydraulic cylinder, the
plunger of which is connected with said piston, the latter baving a rod bent at its
lower end, and adapted to turn by means of said rod a lever connected with the
plug of the discharge-cock of the hydraulic cylinder, said plug being operated by
said lever, or by said rod respectively, as soon as the stuffing-cylinder is about to
finish its path, substantially and for the purpose as described.
Dated this 10th day of August 1894.
