An Improved Machine for Moulding or Shaping Butter.
I, WILLIAM FOSTER of Tungamah in the Colony of Victoria, Farmer, do hereby
declare the nature of this invention to be as follows:
10:
This invention relates to apparatus for putting up butter in moulds, or prints."
In an apparatus constructed according to these improvements the butter is. placed.
in a strong box within which works a presser plate or piston to the back of which a
screwed rod is secured. This rod passes out through the back of the box where there
is mounted upon it a wheel or pulley having a female screw formed through its eye
to engage with the screw thread on the piston rod. The. wheel or pulley is arranged
so as to be incapable of moving longitudinally on the rod, hence when it is rotated,
the rod and consequently also the presser plate, will move longitudinally, the direction
of rotation being governed by the direction of rotation of the wheel or pulley. The
wheel or pulley may be rotated by hand or by power as is well understood. In the
front of the box there are formed three or more square or D-shaped openings, so that
when the butter is placed between the presser plate and the front of the box and the
screwed rod is rotated to drive the presser plate forwards, the butter will be forced
through the openings, and form bars. Above the openings or otherwise conveniently
situated with reference to them, there are slides which may be adjusted so as to
regulate the thickness of the issuing bars to suit the required weights.
Immediately in front of the openings there are mounted a pair of rollers in a
vertical plane, and the surface of the upper roller engraved or formed to produce
any desired pattern, design, or description upon the surface of the bars passing
between the rollers. In front of these rollers and supported upon stationary rails
there is a movable roller tray and to the back of one of the rails there is hinged a
wooden frame carrying cross wires which when; the frame is dropped, cut the bars of
butter into any desired lengths, each.of which forms a "print." A number of these
trays is provided for each machine in order that as soon as one tray is filled, it may be
removed and replaced by an empty one.
A slide may be arranged in front of the openings for the purpose of closing them
when the box is being filled.
f.
In some cases two of the apparatus may be arranged in line so that the one
screw may pass into two boxes and thus perimit one box to be filled whilst the 'other
'is in use.

COMPLETE SPECIFICATION.
An Improved Machine for Moulding or Shaping Butter.
I, WILLIAM FOSTER of Tungamah in the Colony of Victoria,. Farmer, 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 :-
This invention relates to apparatus for putting up butter in moulds or "prints.".

page_text: .
In an apparatus constructed according to these improvements the butter is placed
in a strong box within which. works a presser plate or piston to the back of which a
screwed rod is secured. This rod passes out through the back of the box where there
is mounted upon it a bevel wheel having a female screw formed through its eye to
engage with the screw thread on the piston rod. The bevel wheel is arranged so as
to be incapable of moving longitudinally on the rod, hence when it is rotated, the
rod and consequently also the presser plate will move longitudinally, the direction of
motion being governed by the direction of rotation of the bevel wheel. The bevel
wheel may be rotated by other bevel gears operated by hand or by power as is well
understood. In the front of the box there are placed one or more square or
D-shaped openings so that when the butter is placed between the presser plate and
the front of the box and the hinge cover secured down, then by rotating the screwed
rod the presser plate is driven forward and the butter will be forced through the
opening or openings and form bars which are delivered upon a movable roller tray.
Above the openings or otherwise conveniently situated with reference to them, there
are slides which may be adjusted so as to regulate the thickness of the issuing bars
to suit the required weight. The D-shaped openings are preferably arranged in the
form of a detachable nozzle or die so that it can be easily removed.
Immediately in front of the openings is a lower table to lead the issuing bars on to
the roller tray while mounted in a hinged frame is an upper roller the surface of
which is engraved or formed to produce any desired pattern, design, or description,
upon the surface of the bars that lie upon the roller tray. The movable roller tray is
supported upon stationary rails and to the back of one of the rails there is hinged a
wooden frame carrying cross wires which, when the frame is dropped, cut the bars of
butter into any desired lengths, each of which forms a print." A number of these
irays are provided for each machine in order that as soon as one tray is filled, it may
be removed and be replaced by an empty one.
A movable slide is arranged in front of the openings to close them while the box is
being filled.
In some cases two of the apparatus may be arranged in line so that the one
screw may pass into two boxes and thus permit one box to be filled whilst the
other is in use.
In order that this invention may be better understood, it will now be more
fully described with reference to the accompanying sheet of drawings in
which :-
-
Figure 1 is a part side elevation and a part longitudinal section of the machine ;
Figure 2 a plan thereof with the lid of the presser box open;
Figure 3 an elevation looking from the front end ;
Figure 4 an enlarged view of the mechanism for printing the butter and shewing
the movable stop plate as arranged at front of box; and
Figure 5 a section at a a Figure 4 shewing the stop plate in position over the
front openings.
In these Figures A is a wooden box furnished with a hinged cover A¹; A³ are
thumb screws to retain the cover closed; A³ is a movable presser plate or piston
having a square threaded screw or piston rod A secured to it in such a manner that
it will not revolve. The screw A* has upon it a bevel wheel A' the eye of which is
threaded to suit screw A. The bevel wheel A' gears with the bevel pinions AA secured
on short spindles each of which latter carry a loose pulley A' and a fast pulley A³ to
receive belting for operating the machine, for which purpose handle A' is also
provided. In the front end of the box there is an oblong opening B covered by a
inovable nozzle or die B¹ which has three holes or openings B' formed in it, each hole
having its top surface slightly tapered and its lower surface horizontal as shewn in
Figure 1. These openings or holes B' are furnished with upper adjustable metal
slides B which may be raised or lowered by turning the thumb screws B in their
brackets B; the slides B' being held in place by a metal strap B as shewn. The
nozzle piece is held in position by two tapered wedges B' which press against ledge
pieces B secured to side rails.

page_text: The lower part of the sides of the box extends forwards in the form of two inclined
rails B which support the movable tray C made up of a number of small rollers C¹
furnished with pintles to pass into loops (upon the side bars of the tray. The
arrangement of the tray with a downward inclination tends to facilitate the travel of
the butter. Across and attached to the sides of the movable tray C are laths of
wood Chaving grooves in them to clear the cutting wires D which are stretched
across a suitable frame D' the sides of which are deep enough to allow its top battens
to be clear of the butter bars when the cutting wires have passed through them.
The tension of the wires is adjusted by keys D. while the frame is hinged to the
back inclined rail at D. D' is a handle for the cutting frame; E is a
light slotted
iron frame furnished with sliding blocks E¹ to carry the pintles of the printing
roller E³, which is caused to travel the whole length of the roller tray by cords E³
attached to said blocks E¹ and passing under and over small sheaves E, the front pair
of sheaves being centred on same spindle E. The cords Ę are acted upon by suitable
weights E so as to cause the engraved roller to travel upwards over the bars of
butter to print their upper surfaces. The slotted frame carrying the print roller is
centred at E to allow of its being thrown back as shown in dotted lines (Figure 1)
when the butter is to be cut into lengths by the cross wires. The height of the fore
end of the roller frame E may be adjusted by means of plates E' secured by set
screws E. F is a roller centred upon the rails B to lead the issuing butter bars to
the roller tray. G is a movable stop plate to close the front openings B2 and is held
in position when said roller is removed by a key G¹ bearing against a cross rail G
and by a loop G³ passing over a horn G. H is a drip pan supported by movable
rods H' passing through holes in the legs of the machine.
The mode of operation of the machine is as follows:-
The presser plate or piston is withdrawn to the end of its travel and the stop plate
is placed over the openings B'; the butter is then packed tightly into the box and its
lid is closed and secured. The machine is then put into motion to force the butter
into the openings B2 against the stop plate G, and when this is done the machine is
again stopped to allow the stop plate G to be removed and the roller F to be placed
in position while the slide plates are also adjusted to give the butter bars their proper
depth; the cutting frame and the print frame must also both be thrown backwards on their
hinges. Now, by again giving a forward motion to the presser plate, the butter will
issue in bars on to the roller tray until a sufficient length is thereon, when the
machine is reversed say through half a revolution, and is then stopped, when the print
frame having the print roller at its further end, is lowered inte position, and by
releasing the roller from a slight catch it will travel upwards over the butter bars so
as to print their upper surfaces. Motion is given to the print roller by the weights E
pulling the blocks E' along its grooves. This roller is so engraved that it prints on
the centre of each pat. When the printing is completed the frame is thrown back as
shewn by dotted lines in Figure 1 and the cutting frame is brought down over the bars
of butter to cut them into pieces pats or prints, of the requisite weight, whereupon the
cutting frame is again raised and the movable roller tray bearing the butter prints is
removed and replaced by another similar tray, and the cycle of operations is repeated
as often as may be required.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I desire it to be under-
stood that I do not make any claim in general to a machine for moulding or shaping
butter having a presser plate or piston operated by a screwed rod as shewn in the
