page_text: Improvements in Sausage Filling Machines.
PETER COLLAS, Bridge, Vale, Guernsey, Baker and Grocer, do hereby declare
the nature of this invention to be as follows:-
My invention comprises several improvements in sausage filling machines.
One of the chief and most important part of my invention relates to the several
sized tubes that form the sausage. I provide a rib on each tube on the external
surface with the object of facilitating the removal of air or other gas formed in "
the machine whilst in operation. The rib on the tube rises the skins or casings
that are placed on the tube in readiness for filling. This rib forms a continuous
passage for the escapement of air which accumulates in the filler and generally
finds its way in the sausage, and my invention obviates the pricking of the skins
for the purpose of making an escapement for the air that too often enters the
sausage under the ordinary plain tube or any other methods that are employed. For
quickness and convenience I provide two or more tubes of various sizes preferably
fixed to a metal plate that may be swivelled or pivoted on to another plate that
forms the outlet, and each tube as required is turned on its swivel to the outlet
of filler. Each tube may be provided with a nipple-shaped piece to render the
operator more ease and quickness in slipping the skins on the tubes. These
nipple-shaped pieces are fitted on the end of the tubes. They are then removed
when the skins are properly placed.
Another improvement consists of a small valve attached on the top of container
or cylinder of the machine, for the use of admitting air when the piston of the
cylinder that forces the meat into the skins is being withdrawn.
Another improvement is the tilting of the cylinder when required to refill.
It consists of a spindle attatched to the frame of machine provided with a small
handle and ratchet wheel and pawl. A suitable rod or bar is attatched to the
cylinder to lugs and held by a pin forming a hinge or joint. At the rear end of
rod or bar is secured a chain of a determined length and connected to the spindle
of tilter. To operate the tilter the handle attatched to the spindle is turned and
the chain is made to wind around the spindle, and thereby raises the cylinder.
When the machine is to be operated the cylinder is firmly secured by means of
small hooks fixed on spindle and made to catch in corresponding eyes secured
on the cylinder.
Another important improvement is the method of, working the piston by means
of a screw-threaded guide rod suitably fitted to the frame of machine. The piston
is connected by means of one, two or more rods, but preferably by two firmly
fixed in the piston head, and their other ends are swivelled on the ends of the
travelling screw blocks. My object of the swivell at ends of connecting rods is
for the purpose of raising the piston when withdrawn from the cylinder, so that
this part of the machine may be cleaned with ease.
Another improvement consists in providing an indicator for the purpose of
ascertaining the amount in lbs. of sausage meat that has been used during the
077

page_text: working of the machine, and also register the quantity left in the machine. The
indicator may be fixed on the travelling screw-block, and the scale of weights
made conveniently visible on the frame of machine that supports and contains
the screw-threaded guide rod of the piston.
power. The
The machine is operated by hand, or, if desired by steam or other
hand power machine is provided with a much smaller crank and handle than is
usually adopted, and is situated near the filling outlet so as to enable the operator
to be within easy reach of his work. The combination of well known gearing
mechanism is attatched to the screw rod of the piston for a slow forward motion,
and a fast motion when withdrawing the piston from container or cylinder.
I consider that this machine is designed on more compact principles than any
other machine made for similar purposes, and is worked with perfect ease and
almost noiselessly.
All the parts are encased except the gearing mechanism.
PETER COLLAS, Bridge, Vale, Guernsey, Baker and Grocer, 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:-
My invention consists in several improvements for sausage filling machines.
A very important part of my invention relates particularly to the tube or tubes
forming the sausage.
In the accompanying drawings Fig. 1 shows side elevation and part vertical
section of sausage filling machine.
Fig. 2 represents plan of machine showing more clearly my improved com-
bination of well known gearing mechanism that provides for the working of
piston.
Fig. 3 is a view of the tubes each having a rib for the purpose as hereinafter set
forth.
Fig. 4 is a front elevation of the tubes.
Fig. 5 shows
nipple-shaped piece hereinafter described.
Fig. 6 shows the method of securing the plate of tubes to the outlet plate.
Fig. 7 is a sping bolt hereinafter explained.
To operate the machine, firstly the cylinder B is raised by suitable means as
shown in Fig. 1 and Fig. 2 by turning the handle D to the right. Connected
to the spindle D' is a chain E secured at its other end to a rod or link E. I also
provide means to keep the cylinder perfectly rigid by such means as hook-shaped
pieces e secured to spindle D', fitting in lugs 6 on the underside of cylinder B,
for the purpose of locking the cylinder in a horizontal position. The cylinder B
is mounted on frame of machine with trunions on sides of cylinder into hook-
shaped bearings, thus enabling the cylinder to be raised in any desired position
and also for easily removing the cylinder for the purpose of cleaning the same
when the rod or link E¹ is detached from the chain E or if necessary from the
cylinder B. It will be clearly seen that the hooks e immediately disengage with
lugs b, and the chain E is then wound round the spindle D' whereby the rod E¹
forces the cylinder up and is retained in any convenient position through the catch
or pawl F, engaging with the ratchet-wheel F. In this position the operator is
enabled to fill and re-fill the cylinder in a commodious manner. To bring the

page_text: cylinder back to its proper position the handle D is turned in the reverse direction,
The piston C is made to travel by means of the screw-rod C¹ that is revolved
through the medium of gearing mechanism.
It is essential that the piston should travel slowly when forcing the sausage
meat from the cylinder through the tubes, but on withdrawing the said piston,
I provide means, as shown in Figs. 1 and 2, of gear wheels 11, 12, with a faster
travel which can be shunted in gear by the lever G. To keep the lever G in
position securely a small thumb lever g fitted with a pin g to lever G the said
thumb lever is provided with a spring g' on its under side for the purpose of
keeping the pin g² in the hole g³ when the pressure of thumb is released.
The crank handle C2 is turned by the operator and revolves the shaft H through
cogs and thereby sets in motion the gear wheels I which are fitted on a hollow
shaft H and suitably keyed in a manner to be slid easily along shaft H for the
purpose of altering the gear to fast or slow.
The piston is driven by the screw-rod C¹, revolving through a screw-block 0,
that travels along the screw-rod, and to render less friction and more case I provide
two small rollers J, fitting on axles j, to the sides of travelling screw-block O.
that run on guides J¹, on the frame. The rollers J act as guides and also prevent
the travelling block O from revolving.
The piston C is supported by the rods p that bear in slots p¹, the ends of said
rods being made to fit easily on axles j, so that for convenience the piston may
be raised for the purpose of washing and cleaning the same. When the piston
is raised it is obvious that the screw-rod C¹ and other parts may also be washed,
cleaned, and lubricated.
To the front side of machine an indicator M is fitted to the axle of roller J
for the purpose of ascertaining the correct amount in pounds weight of sausage
meat that has been used during the working of the machine and also to register
the quantity left in the machine. The scale of weights is made conveniently
visible on the frame of the machine that supports and contains the screw-threaded
guide rod of the piston.
With reference to Figs. 3, 4 and 5, a very important part of my invention relates
to the several sized tubes that forms and holds the skins or casings of the sausage.
I provide on each tube A, a rib K on the upper external surface with the object
of facilitating the removal of air or other gases that accumulate in the cylinder B
whilst in operation. At the rear end of each rib is a rim K' with a hole for the
air or other gases to escape on either side of rib when the skins or casings come
close up to rim. The object of the rib K is to rise the skins or casings that are
placed on the tubes in readiness for filling. This rib forms a continuous passage
at its sides for the escapement of air and obviates the pricking of the skins to
allow of the air to escape that too often enters the sausage under the ordinary
manufactured plain tube process.
For quickness and convenience I provide two or more tubes A of various sizes,
preferably fixed to a metal plate L. This plate is slid on to a pin M' which is
fixed on to another plate M2 of the outlet, and each tube as required is turned
on this swivel arrangement to the outlet of filler.
On referring to Fig. 4 small semi-circular slots on the edge of plate L in line
with each tube, are made for the purpose of catching with a spring bolt (see
Fig. 7) on outlet plate M so that when a tube is brought into use
may remain
quite firm and secure. A small thumb screw fitted on the nut 7 may be necessary
to keep the plate more rigid. In plate L I provide a hole L' sufficiently large
enough to place small quantites of meat for convenience and to save time and
also to obviate the withdrawal of the piston from the cylinder.
Each tube may be provided with a nipple-shaped piece N (see Fig. 5,) to render
the operator more ease and quickness in slipping the skins on the tubes. These
nipples are preferably made of metal, nickel plated, to give a smooth surface,
and are fitted by the operator to the end of each tube when required. When the
skins are properly placed they are then removed.

page_text: The machine is designed to be operated by hand power as shown in the drawings,
but if desired can be worked by steam or other power.
The hand power machine is provided with a much shorter crank handle than
is usually adapted, and moreover is situated much nearer to the filling outlet,
thus enabling the operator to be within easy reach of manipulating the sausages
as the meat is being forced into the skins.
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
