Improvements in Pie-making Machinery.
JAMES SAMUEL SMITH of Globe Mills, Lower Globe Street, City Road, Bradford,
Engineer and Machine Maker, do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to save time in the manufacturing of pies by machinery,
and also to make pies of uniform thickness in the crust.
According to my invention, there is a hollow pillar, bored at the top to receive a
ram at its base an inside bracket is fixed which receives a short lever joined to a
connecting rod making a knuckle joint at the juncture. This connecting rol is joined
at its other extremity to a ram which is fitted into the top of the pillar.
At the base of the aforesaid pillar on the opposite side an outside bracket is attached
which receives a foot lever which operates under the short lever spoken of before.
When the foot lever is set in motion the short arm presses the connecting rod
upwards. This foot lever has at its inside end a small runner or pulley, which works
against the short lever, and tends to reduce friction, when pressing the connecting
rods and ram upwards.
In the action of going up the short lever and the connecting rod aforesaid
almost become perpendicular, and by means of the knuckle at the bottom of the
connecting rod and the runner or pulley at the extremity of the lever, a greater
pressure is produced, these parts-the knuckle and the runner or pulley-being then
in contact.
On the top of the pillar is fixed a bridge having hollow arms and a circular top
which receives a die. In each of these hollow arms is placed an adjustable bracket
which holds an L-shaped piece of iron preferably called a stripper which projects to
meet the die mentioned before. Within this bracket is a spiral spring, and through
the bracket and the spring passes the L-shaped piece of iron. Underneath the
spring and through the L-shaped piece of iron is fixed a notch or pin. The action
of the strippers is as follows:-When the ram is forced upwards, a pie tin which
has been placed in a die which is fixed upon the top of the ram, comes in contact
with the strippers and carries them upwards, thereby contracting the spiral
springs. When the ram is lowered, the action of the springs pulls the strippers
down, thereby releasing the pie tin from the die in the circular top of the bridge.

COMPLETE SPECIFICATION.
Improvements in Pie-making Machinery.
1, JAMES SAMUEL SMITH, of Globe Mills, Lower Globe Street City Road,
Bradford, Engineer, and Machine Maker 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 :-
The object of my invention is to save time in the manufacturing of pies by
machinery, and also to make pies of uniform thickness in the crust.

page_text: DESCRIPTIONS OF DRAWINGS.
Figure 1 shows an elevation of a pie making machine, with the inside levers
depressed.
Figure 2 shows an elevation of a pie making machine, with the inside levers
raised.
Figure 3 shows an elevation of a pie making machine with the strippers
shown.
Figure 4 is a section of the bridge with the stripper attached.
According to my invention there is a hollow pillar A, bored at the top to
receive a ram B. At its base an inside bracket C is fixed, which receives a short
lever D joined to a connecting rod E, making a knuckle joint F at the junction.
This connecting rod E is joined at its other extremity R to the ram B which is fitted
into the top of the hollow pillar A. At the base of the aforesaid pillar A, on the
opposite side of the inside bracket C, an outside bracket G is attached,, which receives
a foot lever H operating under the short lever D spoken of before. When the foot
lever is set in motion, the short arm D presses the connecting rod E upwards. The
foot-lever H has at its inside end I a small runner or pulley I which works against the
short lever D and tends to reduce friction when pressing the connecting rods D and E
and also the ram B upwards. In the action of going up the short lever D and the
connecting rod E aforesaid almost become perpendicular, and by means of the knuckle F
at the bottom of the connecting rod E, and the runner or pulley I at the extremity of
the lever H a greater pressure is produced, the parts-the knuckle F and the runner
or pulley I-being then in contact.
On the top of the pillar A is fixed a bridge J having hollow arms and a circular
top K which receives a die L. In each of these hollow arms is placed an adjustable
bracket M which holds an L-shaped piece of iron N preferably called a stripper which
projects to meet the die L mentioned before. Within the bracket M is a spiral
spring O, and through both the bracket M and the spiral spring O passes an L-shaped
piece of iron N. Underneath the spring O and through the L-shaped piece of iron N
is fixed a notch or pin l'.
The action of the stripper is as follows:-When the ram B is forced upwards, a pie
tin T which has been placed in a die S, the latter being fixed upon the top of the
ram B, comes in contact with the strippers N and carries them upwards, thereby
contracting the spiral springs O. When the ram B is lowered the action of the
springs O pulls the strippers N down, thereby releasing the pie tin T from the
die L in the circular top of the bridge K.
The strippers are adjustable in the following way:-
Figure 4. Attached to the inside bracket M is a threaded stud U, on which
works an adjustable collar or nut Q. The object of this adjustable collar or nut Q
is to regulate the width of the strippers N, that they may be contracted or expanded
so as to fit the size of pie required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The combination of the connecting rod E, the short lever D, operated by the
lever H substantially as shown and described.
2. The combination of the strippers N, the spring O, the bracket M and the
nut Q, substantially as shown and described.
3. The general arrangement of the pie making machine substantially as and for the
purposes shown and described.
Dated this 3rd day of February 1897.
