Improvements in and connected with Pie Making Machines."
I GEORGE ROBERT SANZEN-BAKER of 3 Leazes Terraca in the City and County
of Newcastle on Tyne Engineer 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 relates to pie making machines and has for its object to provide
a machine by which the pies can be produced in a more efficient manner than
heretofore.
According to my invention which more particularly relates to machines of the
lever type I arrange the lever carrying the plunger to be operated by foot
instead of by hand power and for this purpose I provide the machine with a suitable
foot lever as hereinafter described.
The plunger lever or a part in connection therewith is adapted to operate a lever,
rod or the like and through it a movable clip for automatically securing the pie
tins in position during raising of the pie and then releasing same.
I also provide a means for heating the pie raising and lidding plunger in a more
efficient manner and to this end I arrange the gas burners so as to dispose or deliver
the flame obliquely within the plunger, and two such burners may be provided and
so arranged.
I will describe my invention with the aid of the accompanying drawings in
which Figure 1 is a sectional elevation of the machine, Figure 2 a plan, Figure 3 a
plan of the foot lever, and Figures 4 and 5 are respectively plan and elevation of
the automatic tin locking device and Figures 6 and 7 are respectively sectional
elevation and plan of the plunger with gas connections and burners.
A is the bed plate having mounted thereon the lever L carrying plunger P
detachably secured thereto by a screwed part or by a slot and collar as at p, or
otherwise conveniently. The plunger P is adapted on operation of the lever L
to decend and raise or form a pie within the tin T in the well known manner.
For securing the tin T in position an interchangeable clip such as C is mounted
en a raised part chaving a ridge and an adjusting screw is provided. The
clip C is suitably formed for receiving and engaging the rear part of the tin T by
its rim t, and for securing it during operation of the plunger I have devised the
arrangement shown at B Figures 1 and 2 and separately in Figures 4 and 5 wherein
a rod or har 1 is connected to the lever L or to its spindle 7 by a small lever band
so arranged that on downward movement of the plunger it draws a clip b¹ over
the rim, the said clip slides in suitable guides such as a and is connected to
the bar Bat 2, In order that the tins may be firmly secured the bar B is bent
as shown at 63 3 or the lever bis dispensed with and the bar B attached to L by
a bent portion as shown dotted at 6°, or a spring or other means for securing
resiliency are provided so that the lever may move a short distance out of or
awuy from the tin T before the clip b¹ is released.
Referring to Figures 6 and 7 the plunger P is provided with gas heating
burners D. D. formed by two branches dd from the supply pipe G the latter
being arranged and connected in the usual manner. The burners 1). 1) are so
arranged that the gas issuing from each shall strike the side of the plunger and

page_text: the flame be directed around its sides in a slightly downward and oblique direction
more or less as shown by the arrows; so that the two flames together, or it may
in some cases be one flame only, cover the whole or nearly so of the base and part
of the sides of the interior of the plunger and on account of their being so directed
the air is drawn in around the central part of the plunger and good combustion
is obtained without the deposit of soot as occurs with burners at present in use
for this purpose and at the same time the plunger is equally and efficiently
heated.
The plunger lever L is provided with a return spring arranged in suitable
position, for instance as at S and the lever L is operated by a foot lever F mounted
in convenient position in the base of the machine frame K as shown; a bracket H
is provided for supporting the lever F which is shown of the bell crank type
centred at hand connected from the part j by a rod or bar J to the plunger
lever at the part or otherwise conveniently, a suitable aperture a² being pro-
vided in the base plate A and its supporting frame as shown, for the passage of
the rod J For securing correct alignment of the plunger P the part of the base
plate A upon which the lever L is mounted is provided with an extended part
or guide M split as shown at m and having a wedge shaped cotter m' for adjusting
same; the lever L is suitably bifurcated to receive the guide as shown at l¹.
In operation the shape of the plunger is changed according as the operation
is for raising or lidding the pies; The pies are raised and lidded in the ordinary
and well known manner except, that by the use of the above described apparatus
the operation can be accomplished more quickly, the tins being simply placed
in position without the necessity of adjusting the clips, the automatic clip securing
and releasing the tins at the proper times as before described, and the operation by
a foot lever instead of by hand further facilitates the quick operation of the
machine.
Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed I declare that what
I claim is
1. The combination of the various parts constituting a complete apparatus
for the raising and lidding of nies all arranged and adapted for operation sub-
stantially in the manner herein described and as shown in the accompanying
drawings.
2. In a pie making machine the use and arrangement in combination with and
adapted to be operated from, the plunger carrying lever qr part in connection
therewith, of a bar or lever and sliding clip for automatically securing and
releasing the tins at the proper times substantially as set forth.
3. In a pie making machine the use in combination with the forming plunger
of the gas burners arranged as described to direct the flame obliquely over the
inner surfaces of the plunger substantially in the manner and for the purposes
set forth.
4. In a pie making machine the combination of a plunger and lever or operating
part with the gas burners arranged as described and the automatic clip arrangement
for securing and releasing the tins at the proper times substantially in the manner
and for the purposes set forth.
