Improvements in Sausage Stuffing Machines.
I, CHARLES WILLIAM HOTTMANN, of 2111 Orianna Street, in the City of
Philadelphia, State of Pennsylvania, U.S.A. Machinist, do hereby declare the
nature of my invention for IMPROVEMENTS IN SAUSAGE STUFFING MACHINES,
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 a machine for stuffing sausages and
for kindred purposes, reference being had to the accompanying drawing, in
which-
Fig. 1, is a sectional view, of a machine constructed in accordance with my
invention.
Fig. 2, is a plan view of the same.
A is a cylindrical casing in which is contained the meat or other material to be
acted upon, and within said cylinder is a plunger B constructed in any suitable
manner and adapted to be traversed in said cylinder to expel its contents through
an opening a in its upper end, the opening communicating with the tube b on which
the skins or filling bags may be placed.
The top of the cylinder A is closed by a coverplate C fitting snugly and locked
in position by a disk c, pivoted to the cover at c and having an operating handle C¹
and provided with inclines c adapted to engage with projections c¹ on the exterior
of the cylinder, and in order to tighten the cover, the inclines are adapted to
slide on the disk c so that they may be driven in tightly under the projecting lips c¹.
Immediately beneath the cylinder A and supporting it by bolts d is a pressure
cylinder D within which is a travelling piston E constructed as set forth herein-
after, the piston E being connected to the plunger B by a piston rod F so that the
admission of steam or other fluid under pressure beneath the piston E will act
through the plunger B to force the material out of the cylinder A.
At the lower end of the cylinder D is a passage for the pressure fluid, and the
admission of fluid is governed by a cock g connected to an operating lever H which
is acted upon by a spring tending to keep the cock closed. The upper end of this
lever is provided with a projecting rod m adapted to be engaged by a pivoted catch
lever M hinged at the upper end of the cylinder. D and having one of its ends
projecting into the path of the piston E, and adapted to be acted upon by the
piston when it reaches the upper limit of its travel to effect the disengagement of
the lever M and allow the spring / to close the valve.
The piston E is made in two sections normally held away from each other by a
series of springs n and between the bevelled edges of the two parts of the piston
are one or more rings preferably formed of asbestos, which when the steam or
other fluid enters under the lower section, is forced outward against the cylinder
and forms a tight packing.
"
When steam is used as the actuating fluid, I prefer to place on the opposite end
of the piston rod F a ring 1 of non-conducting material, such as for instance
asbestos, which will prevent the heat from injuring the material in the cylinder A,
and further protection is afforded by the open space between the cylinders A and D
for the circulation of air.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination in a sausage stuffing machine, of the pressure cylinder D
having an Anon annan and
aniston in said aslindan olindon t having tlata

page_text: and so mounted above the cylinder D as to leave a space between the two for the
circulation of air, a plunger in said cylinder A, a piston rod F connecting the
piston and plunger, rings f₁ of non-conducting material between the ends of
the piston rod F and the piston and plunger, the pressure inlet pipe leading into
the cylinder D, a cock in said pipe, a band lever connected to said cock, a spring
acting on said lever and normally tending to keep the cock closed, and a pivoted
catch lever engaging the hand lever at one end, and having its opposite end in the
path of the piston, substantially as specified.
2. The combination with a pressure cylinder and its piston, of a cylinder A
having an outlet a, projecting lips c' carried by the cylinder A, a cover C for said
cylinder, a disk c centrally pivoted to said cover, an operating handle on said disk,
and a series of movable inclines c³ carried by the disk and adapted to engage with
the lips c¹ substantially as specified.
Dated this 11th day of February 1893.
