PROVISIONAL SPECIFICATION.
An Improved Pie-raising and Lidding Machine.
I, WILLIAM ROBERT GAUDIE, of 1 Railway Street, Jarrow, in the County of
Durham, Confectioner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved pie-raising and lidding machine.
In carrying my invention into effect, 1 employ one or more base plates a lever
and gas-heated plunger and lidding lever device arranged somewhat as follows:
the baseplate adapted to be secured to a bench or table is provided with means
for securely holding the tins or the equivalent thereof in which the pies are to be
made.
Thus radial or other grooves may be formed in which slotted plates or their
equivalent may work and be adapted to be secured therein in any desired position
by screw, clamp, wedge, spring or equivalent power or means.
The plates may be furnished with properly flanged or catch ends to hold the tin
or tins in the required position laterally and vertically.
The plunger lever is securely centred in a convenient position on the base plate
so that the plunger may descend radially towards the moulding place.
The plunger and lidder levers can be readily interchanged in their centres or if
desired the lidder itself, which as in the case of the plunger may vary in size, may
be secured to the face of the plunger, though it may also be secured to a lidder
plate on a lidder lever adapted to descend towards the moulding place as in the
case of the plunger.
Guide and stop blocks may be provided on the base piece to regulate the action
of the levers.
Thus one or a number of pies may be first moulded in succession and afterwards
lidded in like simple manner.

COMPLETE SPECIFICATION.
An Improved Pie-raising and Lidding Machine.
I, WILLIAM ROBERT GAUDIE, of 1 Railway Street, Jarrow, in the County of
Durham, Confectioner, 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 an improved pie raising and lidding machine.
The machine may be made in brass or iron and in order that my invention may
be fully explained and rendered intelligible, I will now refer to the accompanying
drawings, in which
Figure 1 shows a side elevation with the plunger, hereinafter mentioned, shown
partly in section, and Figure 2 a plan with the plunger and lidder levers, hereinafter
mentioned, removed.
Figure 3 shows in side elevation part of the lidder lever, Figure 4 being an half
plan of the underside of same.
Figure 5 is a section on line x y in Fig. 1, Figure 6 showing in elevation a detail
hereinafter explained and throughout this description like letters of reference
designate like parts.

page_text: Referring to the drawings A is a baseplate furnished with two radially placed
bracket lugs A' A' one of which is intended to carry the plunger lever and the
other the lidder lever.
In the bracket A' the plunger lever A is centred, and in the bracket A' a lidder
lever A is designed to work in a similar manner.
In the centre of the baseplate the tin A³ in which the pie is to be moulded is
placed and secured in position by means of certain movable slotted plates A".
These work in radial grooves formed in the base-plate and, by means of thumb
screws or clamps A or an equivalent mechanical device, can be tightened up in any
desired position to suit any desired size of moulding tin.
Thus by loosening a thumb screw a slotted plate can be moved in its groove
towards or from the moulding tin and when it is in the required position it can
be clamped there by the screw which works in a tapped hole provided in the
baseplate.
The inner ends of two of the three slotted plates are flanged up at A to abut
against and hold the tin in position while the inner end of the other slotted plate is
turned up and provided with a hinged catch A°.
When the moulding operation is being performed, the lug on the end of the
hinged catch projects slightly over the edge of the tin and prevents the tin being
lifted up when the plunger is being withdrawn from the paste in the moulding tin.
When the lidding operation is being performed, the hinged catch is thrown over
to one side, as shown in Fig. 6, when the turned up end of the slotted plate to
which the catch is hinged is used to abut against and hold the tin in position as in
the case of the upturned ends of the other slotted plates.
Small flanges F may be formed on the outer ends of the slotted plates whereby
to more easily adjust them with the fingers in the required position as above
described.
bare strengthening ribs on the baseplate.
bare vertically arranged guide brackets to guide the plunger and lidder levers
in their descent towards the moulding tin.
S is a stop against which the plunger or moulding lever abuts at its lowest point
so as to regulate the thickness of the pastry in the pie between the bottom of the
mould M and the moulding tin.
C is a lidder shown screwed onto or against the circular disc d formed on the
lidder lever.
This screw is hollow, in the form of a pipe, to allow the exit of air during the
lidding process.
Any convenient size of lidder can thus be attached to the lidder lever and
similarly a lever fitted with any required size of plunger can be fitted in
bracket A'.
The projection C¹ is for the purpose of guiding or directing the vertical descent
of the lidding lever between the jaws of the guide brackets b'.
P is a pipe secured in any convenient manner on the plunger lever and to it is
connected a flexible gas tube P₁ fitted with a Bunsen burner. The gas issuing
from the end of pipe P into the interior of the mould M, is allowed to burn inside
the mould which thus warms the sides of the latter and this has the effect of
preventing the external metal of the mould adhering to the pastry during the
moulding operation.
The operation of the machine is as follows:-
Firstly a tin is secured as described on the baseplate in the required position.
Sufficient dough is then put into it to form the bottom and sides of the pie. The
plunger lever is brought down and the bottom and sides of the pie are made. This
tin is then removed and another put in its place.
A hundred parts of pies may thus be rapidly made.
The contents of the pies are then inserted in succession and pastry lids laid over
their tops.
The tins or pies thus far advanced in manufacture are then each placed in

page_text: succession under the lidder lever, the descent of which securely lids and trims the
edges of each pie, each of which is quickly removed by hand and replaced by
another tin.
The operations in this manner can be most expeditiously performed.
While lidding, the plunger lever can be thrown back and while moulding, the
lidder lever can be similarly placed out of the way.
If desired, the plunger lever may be removed after moulding and the lidder lever
inserted in its bracket thus dispensing with a separate lidding lever bracket but I
prefer the arrangement shown in the drawing.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A pie raising and lidding machine consisting of a baseplate furnished with
adjustable means for securely holding the receptacle in which the pie has to be
moulded and lidded in position in combination with a plunger and a lidder lever,
the said plunger and lidder levers being centred in lugs formed on an extension of
the baseplate and adapted to descend and ascend radially towards or from the
moulding or lidding place by means of handles formed on the levers so as to raise,
lid and trim the pie the several parts being arranged and adapted to operate
substantially as and for the purposes herein before described and illustrated.
2. A pie raising and lidding machine consisting of a baseplate furnished with
adjustable means for securely holding the receptacle in which the pie has to be
moulded and lidded in position in combination with a plunger and a lidder lever,
the said plunger and lidder levers being centred in lugs formed on an extension of
the baseplate and adapted to descend and ascend radially towards or from the
moulding or lidding place by means of handles formed on the levers so as to raise,
lid and trim the pie the lidder lever being provided with a boss on or to which a
lidder of any required size and shape may be secured the several parts being
arranged and adapted to operate substantially as and for the purposes hereinbefore
described aud illustrated.
3. A combined pie-raising and lidding machine consisting in the combination
with a base-plate having a lug or bracket formed on an extension thereof or two
lugs or brackets similarly formed of a gas heated moulding lever and a lidding
lever, these levers being adapted to descend and ascend radially towards or from
the centrally situated moulding tins either from separate lugs or brackets formed
on the baseplate or from one lug or bracket, in the latter case by substituting for
one of the levers the other lever, the several parts being arranged and adapted to
operate substantially as herein set forth.
