Improvements in Apparatus for the use of Bakers in Moulding Dough
into Tea-cakes, Buns, and the like,
We, CHRISTOPHER DOBSON, of 71, Poulton Street, Kirkham, in the County of
Lancaster, Confectioner and Baker, and ROBERT KENNETH BALCARRAS, of 13,
Victoria Buildings, in the City of Manchester, Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in apparatus for the use of bakers in
moulding dough into tea-cakes buns and the like. In carrying out the said
invention we cause the piece or portion of dough to be moulded to be rubbed or
rolled between a concavity or shallow depression on the upper surface of a table
or board and an upper piston-like domed sheet metal presser moving or sliding
vertically within an annular guide or cylinder. By a gyratory or circumrotatory
movement of the cylinder and presser the dough becomes gradually moulded to
the required rounded form. The depression in the table or board has a central
hole or orifice which affords increased bite or hold to the underside of the piece of
dough being moulded. The domed part of the piston is made with perforations
so as to allow flour for dredging or dusting purposes to gradually work its way
through on to the surface of the dough. Similar apparatus to that above described
may be arranged in multiple form held or mounted within a metal or wooden frame
and may be operated either by hand or by power-in the latter case suitable crank
and lever mechanism being employed to impart the requisite gyratory or
circumrotatory motion.

Improvements in Apparatus for the use of Bakers in Moulding Dough
into Tea-cakes, Buns, and the like.
We, CHRISTOPHER DOBSON, of 71, Poulton Street, Kirkham, in the County of
Lancaster, Confectioner and Baker, and ROBERT KENNETH BALCARRAS, of 13,
Victoria Buildings, in the City of Manchester, 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:-
This invention relates to improvements in apparatus for the use of bakers in
moulding dough into tea cakes, buns loaves and the like. According thereto
the piece of dough to be moulded is rubbed or rolled between a concavity or shallow

page_text: depression on the upper surface of a table or board and an upper piston-like domed
presser that can move or slide vertically within an annular guide or cylinder
hereinafter called a holder. By imparting a gyratory or circum rotatory movement
to the holder and presser, the dough gradually becomes moulded to the required
rounded form. The depression in the table or board may have a central hole,
orifice or depression to increase the bite or hold on the underside of the piece of
dough being moulded. The domed part of the presser is perforated so as to allow
flour for dredging or dusting purposes to gradually work its way through on to
the surface of the dough. Apparatus of the kind above described may be arranged
in multiple form, and be mounted within a metal or wooden frame wherein it can
be operated either by hand or by mechanical power, in the latter case suitable
mechanism being employed to impart the requisite gyratory or circumrotatory
motion.
Figs. 1 and 2 of the accompanying illustrative drawings are elevations at right
angles to one another, and Fig. 3 is a horizontal section on the line of Fig. 1,
showing one construction of apparatus according to this invention.
In this example there are three tables or boards 1 each formed with a number
of shallow concave depressions 1", with it may be additional central recesses 1b, and
arranged to be supported below a movable holder 2 provided with a corresponding
number of piston like or cylindrical pressers 3 having recessed perforated bottoms 3"
so that a number of pieces of dough can be simultaneously operated upon. The
pressers may conveniently be made of sheet metal and the perforated bottoms 3"
may be of concave or dome shaped as shown. The boards 1 are mounted to slide
upon longitudinal bearers 4 on the fixed bed 5 of the framing 5 of the apparatus,
and are moved endways by tappets or projections 6" carried by two endless chains
or bands 6 which are arranged to pass around pulleys 7, 7, that can be rotated
by a hand wheel, not shown, fixed upon the shaft 7" of one of them.
By using three boards, as shown, moulded pieces of dough can be removed from
the forward one and fresh pieces of dough be placed upon the rearward one
whilst the pieces of dough on the middle one are being operated upon, thus
admitting of a large output from the apparatus. The holder 2 consists of a wooden
board formed with a number of circular holes to receive the pressers 3. These
pressers are capable of being slidden by hand a greater or less distance up or down
in the circular holes in the holder 2 to suit the sizes of the loaves, buns or the
like to be made, the perforation 3ª in the concave or dome shaped bottoms 3
serving to allow dry ffour to work through upon the dough in process of being
moulded. The pressers 2 may be weighted in any suitable way, it may be by
loose shot placed in them and which, by rolling about, will assist the flour to pass
through the perforated bottoms 3. The holder 2 is suspended by pins 7, 7 from a
pair of crank discs 8, 8ª fixed upon vertical spindles 9, 9" which are suitably
rotated for the purpose of imparting the desired gyratory or circumrotatory motion
to the holder and the pressers 3 carried thereby. For this purpose in the example
shown there is conveniently mounted at the upper part of the framework of the
machine, a driving shaft 10 provided with fast and loose pulleys 10", 10b driven by
a belt from a suitable source of power. At one end of the spindle 10 is a bevel
gear wheel 11 that engages with another bevel gear wheel 12 the sleeve 12" of
which rotates within a bracket 13 fixed to the framework 5". Passing through
the gear wheel 12 and rotated thereby is the vertical spindle 9 which is provided
with a long key or feather 9* than can slide freely in a corresponding keyway in
the gear wheel 12 and enables the said spindle to be raised or lowered. The
vertical spindle 9" is arranged to slide vertically in a bearing bracket 13" and, in
the example shown, is provided with a pulley 14" by which is can be rotated from
a similar pulley 14 on the spindle 9 through an endless belt 15. If desired the
spindle 9 might be driven from the shaft 10 through gearing like the spindle 9.
The vertical spindles 9, 9* and their attached parts are carried by means of
brackets 16, 16 upon which rest collars formed on the said spindles, the said
brackets being fixed to a frame or support 17. In order that the vertical distance

page_text: between the concave bottoms 3ª and depressions 1ª on the pressers and board
respectively can be varied to suit requirement the holder is made vertically
adjustable. For this purpose the frame or support 17 carrying it, is made capable
of being raised and lowered at its upper part of angle iron for the purpose of being
guided in its vertical movements by the framing 5" of the apparatus. It is held
in the raised position by means of balance weights 18 adapted to counter-balance
the frame 17 and the parts carried thereby, the said weights being suspended by
chains 19 that pass around guide pulleys 20 from the lower part of the frame or
support 17 which is provided with a suitable bar or rail 21 by which the frame
with holder, pressers and attached parts can be forced down to the required extent
by a foot of the operator. The lower end of the frame 17 consists or rods connected
together by cross stays 17*.
The amount of gyratory movement imparted to the holder 2 and pressers 3 can,
if desired, be varied to suit different requirements by forming the discs 8, 8" with
several holes 8* of varying eccentricity and into either of which the crank
pins 7, 7 can be placed. Or such adjustment can also be effected by making
the crank pins radially adjustable in the said discs.
As will be seen the construction of the apparatus hereinbefore described is such
that when the pressers 3 are lowered upon pieces of dough placed upon the board 1
below the pressers and the vertical spindles are rotated, a gyratory movement will
be imparted to the holder 2 and pressers 3 carried thereby so that each piece of
dough will be rubbed or rolled between the board and the presser above it, whereby
the said piece of dough will become worked up in a manner similar to that effected
by hand working and will be gradually brought to the required rounded form.
The apparatus is specially advantageous for producing the top and bottom
pieces of dough required for making loaves of bread of the kind known as cottage
loaves.
The shape of each presser may be variously modified provided it is capable of
rising and falling and will upon being operated as described rub or roll a piece of
dough placed between it and the board so as to work the same after the manner
of hand worked dough. Also the table or board 1 may in some cases be without
the depressions 1°, and instead of being stationary may also have a gyratory motion
imparted to it but in the opposite direction to or at a different speed from that
imparted to the holder.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. Apparatus for moulding dough wherein a piece of dough can have a gyratory
or circumrotatory movement imparted thereto substantially as herein described for
the purpose specified.
2. Apparatus for moulding dough comprising a table or board and one or
more vertically movable pressers arranged and operating substantially as herein-
before described for the purposes specified.
3. Apparatus for moulding dough constructed arranged and operating
substantially as hereinbefore described with reference to and shown in the drawings
annexed.
