IMPROVEMENTS IN MACHINERY AND APPARATUS FOR MOULDING PASTE
Year: 1884

page_text: I JOHN HUNT of Baldwin Street, Bolton in the County of Lancaster, Machinist,
do hereby declare the nature of my Invention for "IMPROVEMENTS IN MACHINERY
AND APPARATUS FOR MOULDING PASTE," to be as follows:-
My improvements in machinery or apparatus for moulding paste consists of a
fixed bottom mould of the size and shape of the pie to be moulded, also. of an
inside mould, which is fixed to a ram or spindle worked up and down by a weighted
lever and link. This link is provided at the top end with a jaw or fork coupling
to both sides of the ram on suitable centres, giving an improved action as well as
stability. To prevent the ram twisting and ensure a perfectly correct motion, the
mould block is provided with a projection slotted to fit on a suitable preparation
on the inner side of the frame of the machine.
The top mould block is provided on its underside with projections in which is
fitted or fixed the top mould leaving a cavity open on the outer edge to allow of a
supply of air for combustion. In this cavity placed a circular gas burner of
suitable diameter to distribute the heat entirely over the mould, the gas being
supplied by a pipe passing through the stand or frame.
The ram immediately above the crosshead carrying the mould block is provided
with a spiral spring or cushion to retard the action of the weight on the lever
when liberated.
These improvements are also applicable to a pie lidding machine, which is
similar in every respect with the exception of the moulds.
In another arrangement I attach to the bottom of the ram a double crosshead
provided with the blocking and lidding moulds and the necessary appliances, wherein
both operations are performed in one machine, or the crosshead can be constructed
to carry two or more blocking moulds, by which the same number of pies can be
blocked at one operation.
In making or moulding paste or pies without tins, in which case metallic hinged
moulds are employed, the bottom ends being provided with removable baking tins
or carriers on which the pies are removed from the machine, and thus prevents
damaging or fingering. To enable the paste to be readily removed from the moulds
and prevent sticking by a raised vertical ridge which would tend to destroy it,

page_text: the metallic hinged moulds are divided on the opening side at an angle of 45 degrees
or thereabouts, thus distributing the ridge over an extended surface, which must of
necessity increase the strength of the paste mould. The bottom mould or plate
and tin, together with the top mould are heated by gas or other equivalents to
facilitate the pressing and removal of the paste.
COMPLETE SPECIFICATION.
Improvements in Machinery and Apparatus for Moulding Paste.
I JOHN HUNT of Baldwin Street, Bolton in the County of Lancaster, Machinist,
do hereby declare the nature of my Invention for "IMPROVEMENTS IN MACHINERY
AND APPARATUS FOR MOULDING PASTE," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My improved machinery or apparatus for moulding paste consists of a fixed
bottom mould with a movable top mould and in mechanism for operating the latter,
which will be readily understood by referring to the annexed drawings which I will
now proceed to describe. Fig. 1 is a side elevation and Fig. a front view of my
improved machine for moulding pies. A is the fixed bottom mould which contains
the tin pie dish B, the latter being held in position by the gauge peg C. The
inside mould D is fixed in any convenient manner to the ram or spindle E moving
up and down in the standard F by the action of the weighted hand lever G and
link H. This link is provided at the top end with the jaw or fork H¹ coupled to
each side of the head I of the ram or spindle E by the centres J, which give an
improved and equal action to the same as well as stability. To prevent the ram or
spindle E twisting and to secure a perfect vertical motion the mould block K
carrying the inside mould D is provided with the slotted projection L which fits
and slides on the slide bar M on the inner side of the standard F of the machine.
The top mould block K is provided on the underside with the projections a in
which is fitted or fixed the top mould D, leaving the cavity b open on the outer
edge to allow of a passage for air to aid combustion. In this cavity is placed the
circular gas burner d to distribute the heat entirely over the top side of the mould;
the gas being supplied through the pipe d which is attached to the flexible or
india-rubber tube Y to allow of the motion of the ram & mould.
The mode of operation is as follows:-The pie tin B containing a piece of paste
is placed in the bottom mould A and the hand lever G is drawn down to the'
position shewn in dotted lines in Fig. 1, thus bringing the inside mould D into the
pie dish B, forcing the paste into the required shape.

page_text: Figs. 3 and 4 are a side and front view of my improved machine wherein
I attach to the bottom of the ram or spindle E the double crosshead N provided
with the blocking and lidding moulds D and P respectively, by which both
operations are performed in one machine. The crosshead N is constructed so that
the blocking and lidding moulds can be removed and readily changed from one
size to another, and if desired two blocking moulds can be attached by which the
same number of pies can be blocked at one operation. I do not confine myself to
the exact form of the crosshead N as it may be constructed to carry three or more
blocking or lidding moulds.
Figs. 5 and 6 are side and front elevations of my improved machine arranged for
forming the lids on pies the mould P is secured in any convenient manner to the
bottom end of the ram or spindle E as in the blocking machine, which mould is
made with a plain, fluted, or ornamental surface: the pie dish B containing the
pie is placed in the bottom mould A with a piece of paste for the lid on the top of
it. The other parts of the machine and the action of the same are similar to those
before described. The flange or mould block K. carrying the lidding mould P is
provided with the slotted projection L which slides on the guide or slide bar M on
the inner side of the standard F of the machine. The lidding mould P is heated
by the gas jet d mounted on flange or mould block K, being coupled to the flexible
tube Y as in Figs. 1, 2, 3 and 4.
The method of operating this machine is similar to that described in Figs. 1 and 2
by which the pie lid is pressed into shape, at the same time cutting off the super-
fluous waste.
For the purpose of retarding the action of the weight W on the lever G when
liberated, the spiral spring T is provided on the ram or spindle E immediately
above the crosshead or mould block to form a cushion and preserve the machine
from shock or strain, which is also applicable to the pie lidding machine shewn in
Figs. 5 and 6, which is similar in every respect with the exception of the moulds.
Fig. 7 is an enlarged part side elevation of my improved pie moulding and,
lidding machine, and Fig. 8 is a sectional plan of same through line A¹ B₁. On
the foundation or bed plate is mounted suitable metallic hinged moulds for making
or moulding paste or pies without tins: the bottom moulds A are attached to the
circular plate which is centred into the foundation or bed plate X of the machine
by the hollow centre g. The hinges h of the moulds are secured to the centro
part by the pins l, being divided on the front side diagonally as shewn in Fig. 12,
or vertically as in Fig. 13. When being used for moulding paste they are closed as
shewn in Figs. 7 and 9, being locked by the swivelling latch m, shewn in Figs. 9
and 12. When the paste is moulded the hinged mould is opened, in which case the
removable baking tins or carriers p are slightly removed, by the action of the inner
edges of the hinges, from the back of the mould as shewn in Fig. 10, allowing the
paste moulds to be removed without damage from fingering. The pins descend
to the underside of the plate fand are provided with the levers and connecting
rods 8, by which the hinges on each side are connected and operated, as shewn in
Fig. 14, which is a plan of the underside of the circular plate f.
Fig. 11 is an outside elevation of the metallic hinged moulds shewn in Fig. 9,
and Fig. 13 is a front view of Fig. 10.
After the pie is moulded in the hinged mould by the mould D the circular
plate with the moulds is swivelled round by the handles z, shewn in Fig. 12, to a
position immediately under the lidding mould P. This position is determined by
the slots 2 cut in the face or edge of the plate f, into which slips the lock bar 3
secured on the front of the foundation plate X by the action of the spiral spring 4.
The lock bar is released from the slots 2 in the platef by pulling outwardly the knob
or handle 5 attached thereto, when the same can be revolved and swivelled round
at will, during which, the point of the lock bar is pressing against the face or edge
of the plate until the next slot is reached when the correct position is maintained
for blocking and lidding and so on continuously.

page_text: The hinged moulds, plates, and tins or carriers together with the top mould D
are beated by gas from the gas burner d, which can be connected in any convenient
way to the flexible or india-rubber pipes Y to facilitate the pressing and removal
of the paste from the moulds.
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
1. The construction and arrangement of the improved machine shewn in Figs. 1
