Improvements in and relating to Machines for use in the Manu
facture of Cakes, Biscuits, and Confectionery generally.
I, JOSEPH BRADY, of 133 High Street Shadwell E. Mechanic 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 provide movable moulds to machines used in the
manufacture of cakes biscuits and similar articles. For the purpose of my invention
I form a slot in the lower end of the dough box on either side of which I fit by
means of a groove or in other suitable manner, the moulds, which may be cut and
formed as to turn out any shaped cake or similar article, and in any quantity.
I attach to the mould or moulds a handle of any suitable length and shape to
enable the operator to withdraw same at any time and with facility for another mould
or die of different size form or pattern to be quickly placed in position instead of
same and ready for immediate use.
:
I further propose that instead of employing a toothed wheel with a fixed pin at
one portion from the centre, to so alter and adjust the throw of the plunger by means
of a portion of metal working on a boss to the face of the wheel, grooved and so
tapered as to be capable of receiving a corresponding portion of metal to take
therein having a pin or stud head at right angles thereto connected to the driving
shaft. A similar application would also be used by me as on the crank shaft for
regulating the revolving web that carries the moulds or pans; and I so provide that
the pin to which the side connecting rods are attached when in position, can be so
adjusted and regulated that the throw of the side lever that works the ratchet
wheel and carries a bevil pinion that works in a bevil or spur wheel keyed on end for
working the plunger to give the required quantity of material desired for the cakes
to be made from. But when it may be desired to alter or vary the necessary or
desired quantity to supply for different forms or sizes of cakes, I propose to arrange
for and use in connection therewith a register or indicator by which the operator
or workman can exactly set and vary the stroke in a moment to suit the particular
purpose and object desired, which I may effect by shifting the sliding grooved block
with pin attached to centre with an agreed index, by means of a regulating screw
The said
specially provided for this particular purpose and in connection with same.
register or indicator acting as a distinct guage or guide for the particular purpose
just referred to.
The said grooved or tapered portions of metal referred to having like portions of
metal to take in each and to which latter portions of metal, threads are formed
therein into which screwed rods work so as to render them capable of being raised or
lowered either to the upper or lower points towards or from the centres of the main
crank shaft and so enable the quantity of material required or desired to be regulated
and delivered for use.
In front of the division space or the dough receptacle or chamber I provide or
insert a slide, dove-tailed grooved or channelled to take into corresponding grooves
and position securely and yet capable of being easily lifted out of same, and
having openings to suit the particular object, size or purpose of the articles to be
made; and facing against corresponding slotted openings (instead of holes) to the
dough chamber.
For a particular class of cake that may be desired I provide and place in position
a suitable mould or die and secure same for the time, and work by means of the
crank shaft and connections to give the necessary feed or supply to the row of
moulds which come directly beneath, as the tray is carried along by the revolving

page_text: web and the arrangement for working the vertical cutting or guillotine knife is
likewise regulated to act with efficiency for the particular purpose and with
precision.
By means of employing bevil wheels and pinion as proposed by me the stroke of
the plunger can be much better regulated and will work with greater rapidity, than
in the use of a worm and wheel such as has heretofore been in use for a similar
object.
In the accompanying drawings Figure 1, (Sheet 1) and Figure 2 (Sheet 1) are
both side elevational views, of opposite sides of the machine.
Figure 3 (Sheet 2) is a front or end view of Figures 1 and 2 (Sheet 1), looking
toward the end of the dough chamber or receptacle. In which views A, is the main
frame upon which the dough .box B is firmly mounted in the upper part of the
framé and suitable provision is made for feeding it from time to time; a piston B¹
is provided within the said dough box B (shewn by dotted lines) to which a piston
rod E is connected passing through the other end of the dough box at F, and is
actuated by mechanism as shewn connected.to same. G is the front end of the
dough box wherein suitable openings are formed and the dough is expressed from.
time to time as regulated and in the proportion desired.
A revolving web or endless apron H is caused to travel by means of rollers J
and K which it surrounds, and carries upon it and presents in succession the tray
or trays with the rows of moulds formed or placed thereon to the feeding or front
portion of the dough chamber and which are so gauged as to present themselves in
succession beneath saine. L is a vertical cutting or guillotine knife worked by
means of cranks L', on shaft L2 and connecting rods L³ (shewn at Fig. 3 Sheet 2)
which is regulated to work in guides close against the face of the movable mould M
or face close to the dough chamber at end G.
".
Figure 4 Sheet 2 is a slightly enlarged view to that portion shewn at Fig. 3, of
the movable mould. This view shews the die plate M' being just lowered into position
and being of a wedge form or shape at the sides it easily drops into position and
when desired to be lifted or raised to alter and give other form or number of
patterns or dies, it can be readily done and lifted out by means of the handle M², as
shewn, and another inserted into position in like manner. Although but three dies
are shewn, it must be understood that there may be any other suitable number and of
different shape and form to same.
Figure 5, Sheet 2, is a detached view, slightly enlarged, to that previously described
by me to alter and adjust the throw of the plunger likewise to regulate and adjust
the working of other parts of the apparatus, which consists of a portion of metal or
frame N, grooved, slotted or tapered, working on a boss, and capable of receiving in
the said groove a corresponding portion of metal O, to slide and take therein having
a pin or stud R connected thereto. The latter can be so adjusted to and from the
centre of the crank shaft by means of a screwed rod P, which works in the screwed
portions of the frame and bolt provided or collar and having a square head Q to
work same.
The main shaft L2 of the machine is mounted in suitable bearings on the side
frames A and may be driven by any available motor or power. S is the fly wheel
keyed onto the main shaft I, at one end and having a spur wheel T, on same at the
other end gearing into a similar spur wheel U, working in a suitable bearing and
shaft on the main frame by which the knife is operated. V, is a screwed shaft on
one end of which a bevil wheel is fixed working into a corresponding pinion or
wheel to which motion is given by means of a connecting rod as shewn from the main
shaft. W is a small hand wheel to assist in withdrawing the piston after it has been
#impelled forward.
The several operations and method of manufacturing cakes and in respect to the
mechanism employed I have not fully.described as the ordinary principle is known
and already in use; but in my arrangement I have somewhat simplified same both in
principle and in general arrangement.

page_text: 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 :
"In providing movable moulds being of a wedge form or shape to take into dove-
tail receptacles formed in or about the front box of the dongh chamber and capable
of being readily lifted for another movable mould of different pattern to take its
placa. Also in the means of regulating or altering various parts of the apparatus
substantially in manner and for the particular purpose herein described and
illustrated.'
