Improvements in Sausage Filling Machines.
I FREDERICK JOHN GARDNER trading as John Gardner and Son of Smithfield
Works, Bradford Street, Birmingham in the County of Warwick, Machinist do
hereby declare the nature of this invention to be as follows:-
My invention consists of the improvements hereinafter described in hand worked
sausage filling machines, whereby the said machines are made more efficient in use
than ordinary machines and their manufacture is economized.
My invention consists first of the following construction and arrangement of
parts for raising the cylinder for containing the meat into an inclined position for
filling it and for holding down the filled cylinder in its horizontal position during
the action of the piston for forcing out the meat.
For these purposes, I arrange under the mouth end of the cylinder a nearly
vertical crank lever carried by a horizontal shaft or axis turning in the framing of
the machine. This crank lever has motion through about a right angle in a
vertical plane and is operated by a handle external to the frame of the machine.
The extreme end of the lever carries an anti-friction roller which bears against the
underside of the cylinder. The upper end of the handle of the crank lever has a
catch which when the cylinder is in its horizontal position bears against one of the
front studs on the cylinder and holds down the said cylinder. When it is required
to lift the cylinder into an inclined position for filling it, the bandle is turned down
into a horizontal position. By this motion the lever is lifted and its roller bearing
against the cylinder raises the said cylinder into an inclined position; the said
lever being carried by the motion of the handle beyond the centre on which it turns,
that is, to the opposite side of the centre to that which it occupied when the
cylinder was in its horizontal position, so that the said lever firmly supports the
said cylinder and there is no tendency in the lever to fall, hence a separate catch
for bolding the cylinder in its raised position is rendered unnecessary. When the
handle is raised into a vertical position the lever descends and permits of the
descent of the mouth end of the cylinder into its horizontal position.
My invention consists further in so arranging the weight of the cylinder that it
is nearly balanced on the rear pivots on which it turns so that the raising and
lowering of the cylinder is much facilitated.
My invention consists further in using a guide block, through which the
reciprocating rack bar carrying the forcing piston works, made in one piece,
instead of using several guide bars as usual. The guide block is passed. by an end
motion into its place at the top of the front upright of the machine and is fixed by
a single screw pin, the said block being provided with properly shaped seats for
supporting the sliding rack bar.
My invention consists further in making the whole of the frame of the machine
by casting in one piece, instead of in several pieces as usual, whereby great
compactness in the frame is secured as well as facility of manufacture.
In making the frame according to my invention I provide it with end stay bars
in one piece with the sides of the frame. I also provide one of the sides of the
frame on its inner face with a projecting sleeve or bearing for the axis of the
cylinder lifting lever hereinbefore described to work in. I also provide the top of
the front ends of the sides of the frame with cross, bearings for the driving axis to

in by which the quick back or return motion is given to the reciprocating rack
bar of the piston; and also openings in the top edges of the sides of the frame
for the pair of pivots and pair of studs on the cylinder to turn in and take into.

Improvements in Sausage Filling Machines.
I FREDERICK JOHN GARDNER trading as John Gardner and Son of Smithfield
Works Bradford Street, Birmingham in the County of Warwick, Machinist, do
hereby declare the nature of my invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
My invention consists of the improvements hereinafter described in hand worked
sausage filling machines whereby the said machines are made more efficient in use
than ordinary machines and their manufacture is economized.
My invention consists first of the following construction and arrangement of
parts for raising the cylinder for containing the meat into an inclined position for
filling it and for holding down the filled cylinder in its horizontal position during
the action of the piston for forcing out the meat.
For these purposes I arrange under the mouth end of the cylinder a nearly
vertical crank lever the horizontal shaft or axis of which turns in the framing of
the machine. This crank lever has motion through a little more than a right angle
in a vertical plane and is operated by a handle external to the frame of the
machine. The extreme end of the lever carries an anti-friction roller which hears
against the underside of the cylinder. The upper end of the handle of the crank
lever has a catch which when the cylinder is in its horizontal position bears
against one of the front studs on the cylinder and holds down the said cylinder.
When it is required to lift the cylinder into an inclined position for filling it the
handle is turned down slightly beyond a horizontal position. By this motion, the
lever is lifted and its roller bearing against the cylinder raises the said cylinder
into an inclined position, the said lever being carried by the motion of the handle
beyond the centre on which it turns; that is, to the opposite side of the centre to
that which it occupied when the cylinder was in its horizontal position, so that the
said lever firmly supports the said cylinder and there is no tendency in the lever to
fall, hence a separate catch for holding the cylinder in its raised position is
rendered unnecessary.
When the handle is raised into a nearly vertical position
the lever descends and permits of the descent of the mouth end of the cylinder into
its horizontal position.
My invention consists further in so arranging the pivots of the cylinder that it is
nearly balanced on the said pivots on which it turns so that the raising and lowering
of the cylinder is much facilitated.
My invention consists further in using a guide block through which the
reciprocating rack bar carrying the forcing piston works, made in one piece instead
of using several guide bars as usual. The guide block is passed by an end motion
into its place at the top of the front upright of the machine and is fixed by a
single screw pin, the said block being provided with properly shaped seats for
supporting the sliding rack bar.
My invention consists further in making the whole of the frame of the machine
by casting in one piece, instead of in several pieces as usual, whereby great
compactness in the frame is secured as well as facility of manufacture.

h
a is the cylinder turning on the pivots b, b situated a short distance from the rear
end of the cylinder, the said pivots turning in the bearings c, c at opposite sides of
the rear end of the frame of the machine. By thus arranging the pivots on which
the cylinder turns with respect to the rear end of the cylinder, the said cylinder is
nearly balanced on the said pivots so that the raising and lowering of the cylinder
is much facilitated. Near the front or mouth end of the cylinder are studs d, d
which when the cylinder is in its lowered position as represented in Figure I take
into the seats e, e on the sides of the frame; is the forcing piston and g the rack
bar of the same. For raising the cylinder on its pivots b, b into the inclined
position represented in Figure 2 and for holding down the filled cylinder, in its
horizontal position during the action of the piston for forcing out the meat, I use
the lifting and holding down lever h, ha, ha, ha, h. This lever is a crank lever, the
handle part working outside the frame of the machine and being nearly vertical
when in its holding down position. The inner horizontal part h² of the crank
constitutes the shaft turning in the sleeve or bearing i on the frame of the machine,
and the extreme cranked part h³ of the lever carries the anti-friction roller /* which
in its lifting action bears against the underside of the cylinder. The upper end of
the handle part h of the crank lever has a catch ' which when the cylinder a is in
its horizontal position as represented in Figure 1 is brought over and bears against
one of the front studs d on the cylinder and holds down the said cylinder. After
the meat has been forced from the cylinder by the operation of the piston f and it
is required to lift the cylinder into the inclined position represented in Figure 2
for refilling it, the handle h of the crank lever is turned down into the position
represented in the said Figure 2, that is, from the nearly vertical_position
represented in Figure 1 to the nearly horizontal position represented in Figure 2.
By this motion of the crank lever the inner crank part h³ carrying the roller 4* is
raised and the said roller bearing against and advancing on the underside of the
cylinder towards its rear end, raises the said cylinder into the inclined position
represented in Figure 2, the lifting of the cylinder being facilitated by the
balancing of the said cylinder herein before mentioned. The motion of the crank
lever from its holding down to its lifting position carries it to the opposite side
of the centre on which it turns from that which it occupied when the cylinder was
in its horizontal position so that the said lever firmly supports the cylinder in its
inclined position and there is no tendency in the lever to fall, hence a separate
catch for holding the cylinder in its raised position is rendered unnecessary.
lifting action of the lever is limited by its inner crank part 3 bearing against the
stop on the sleeve i in which the lever turns. After the inclined cylinder has
been filled, the handle his raised into the nearly vertical position Figure 1. The
inner or crank part of the lever and its roller thereby descend and permit of the
descent of the mouth end of the filled cylinder into its horizontal position,
The

raised position engaging with the stud d and holding down the .cylinder. ready for
the forcing. out operation.
The slow motion of the piston f in its cylinder 6 for forcing out the meat
therefrom is effected through the pinion k on the end of the.axis 1, the said pinion k
gearing with the large toothed wheel'm on the axis n carrying the pinion p, the
latter gearing with the rack of the piston bar g. By fitting the handle q upon the
square end of the axis and turning the said handle in the direction indicated by
the full lined arrow in Figure 1, the piston may be forced into the cylinder b and
by reversing the motion of the handle q; that is, moving it in the direction of the
dotted arrow in Figure 1, the piston may be withdrawn from the cylinder. When
however a quick return of the piston fis required, the handle q is fitted upon the
square end of the pinion axis n as indicated in dotted lines in Figure 1, and the
pinion p may be rapidly rotated for the quick return of the piston. The recipro-
cating rack bar
9, carrying the forcing piston f, works in the guide block made in
one piece (see Figures 6 and 7). The said solid guide block r is passed by an end
motion into the box s at the top of the front upright of the frame, and is
fixed in the said box by the single screw pin u. The said guide block r is
provided with properly shaped seats for supporting the T shaped sliding rack bar g
of the piston as represented.
"
The whole of the frame for supporting the several parts of the machine is made
in one piece by casting. That is to say, I provide the cast frame with the rear
upright and cross stay in one piece with the sides of the frame and also with the
front upright t and its box s and cross stay in one piece with the sides of the frame.
One of the sides of the frame has the projecting sleeve or bearing i for the axis of
the lifting lever to work in and also the stop for limiting the lifting action of the
said lever. The top of the front bracket t has cross bearings t³, t² in which the
driving or pinion axis n works and also with bearings, near the bottom of
the sides for the pinion axis to work in. The tops of the sides are also provided.
with the pairs of seats c, e for the pivots b, b and studs d, d to turn in and take into
as represented.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention ;-

illustrated in the accompanying drawings for raising the cylinders of hand
worked sausage filling machines into their inclined position and for supporting
them in that position and also for holding down the filled cylinders when in their
horizontal position.
Secondly. The arrangement of the pivots on which the cylinders of hand worked
sausage filling machines turn herein before described and illustrated in the accom-
panying drawings whereby the cylinder is nearly balanced on its pivots and the

Thirdly. Making the guide block through which the reciprocating rack bar of
the forcing piston works, in one piece and fixing it in its place in the frame of the
machine by a screw pin substantially as herein before described and illustrated in
the accompanying drawings.
Lastly. Making the frame of the sausage filling machine in one piece by
casting, the said cast frame being provided with the necessary bearings and parts
