PROVISIONAL SPECIFICATION.
Improvements in Dough Moulding Machines.
I, GEORGE LEWIS, of Park Street, Wellington, in the County of Salop,
Baker, do hereby declare the nature of this invention to be as follows:-
My invention relates to a new dough moulding machine and its object is to
mould dough into shape for loaves and other baked articles by machinery
dispensing with the usual hand labour at present employed.
My invention consists in a machine having a hollow cylinder and a rotating
central former or formers whereby the dough is rolled round between the cylinder
and the former and after taking the proper shape is discharged at a suitable
aperture.
In one method of carrying my invention into effect I construct a fixed cylinder
and within it I mount a rotating shaft driver. by worm and worm wheel, bevil
wheels or other suitable gear. On the central shaft I mount one or more rotating
discs having expanded portions forming the circumferences of the said discs; these
expanded portions are arranged more or less in semi-circular form so as to produce
an annulus between the semi-circular circumferences and the shape of the interior
of the fixed cylinder. An annular chamber is thus formed between the rotating
disc former and the interior circumference of the cylinder. I arrange in this
annular chamber or rather entering into the chamber through the side fixed
cylinder, a convenient opening, and by this opening I insert the lump of dough-to.
be moulded. The disc rotating slowly rolls the dough round and round against
the interior of the cylinder and forms it to the section of the space produced by
the edge of the disc, and the surface of the cylinder. When the dough has been
rolled round a certain portion of the circumference of the cylinder it comes
opposite to a discharge opening and is there discharged ready for putting the two
halves together. The cylinder may be filled with discs having different shaped
edges so forming with the internal surfaces of the cylinder different shaped
chambers for moulding the dough.
The cylinder may be bored out with a smooth interior in which case the whole
of the shape is given by the configuration of the edge of each disc or it may be
formed in a series of rings or ridges to assist in giving the desired outline to the
dough. The same cylinder may be used simultaneously for a number of different
shaped loaves or pieces of bread, each disc being arranged accordingly and suitable
apertures for filling and discharging being provided through the sides of the
cylinder opening to each dough chamber.
Instead of arranging the grooves or recesses in the edges of the discs as small
circular recesses, I sometimes arrauge within the cylinder a former of spiral con-
figuration and in this case each piece of dough is rolled spirally along the cylinder,
entering at one end and discharging towards the other end. The discs or castings
may be keyed upon the shaft in any number, and loose rings may be driven into
the cylinder to give the requisite configuration to the cylinder at the parts forming
the dough chambers.
Instead of causing the discs to revolve the barrel or cylinder may be caused to
revolve and the discs held stationary.

I, GEORGE LEWIS, of Park Street, Wellington, in the County of Salop,
Baker, 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 a new dough moulding machine and its object is to
mould dough into shape for loaves and other baked articles by machinery
dispensing with the usual hand labour at present employed.
My invention consists in a machine having a hollow cylinder and a rotating
central former or formers whereby the dough is rolled round between the cylinder
and the former and after taking the proper shape is discharged at a suitable
aperture.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to -
Figure 1 is a side elevation with part section representing one form of my
improved machine.
Figure 2 is an end elevation of the machine with the mouth piece removed.
Figure 3 is an end elevation of the mouth piece.
Figure 4 is a part plan showing the arrangement of the driving gear.
Figure 5 is a part section through the rotating discs or moulding wheels.
Figure 6 is a similar view representing a modified form of moulding wheel.
Figure 7 is a similar section showing a moulding wheel suitable for long loaves
such as French loaves.
The same reference letters in the different views indicate the same parts.
In one method of carrying my invention into effect I construct a fixed cylinder
or drum A and within it I mount a rotating shaft B driven by worm C and worm
wheel D, or by bevil wheels or other suitable gear. The shaft is supported by the
standards E E bolted or secured to the base of the machine. On the central
shaft BI secure the forming disc or moulding wheel F and upon the shaft
I mount a like dise or wheel G. The disc or wheel G is loose on the shaft B but
is keyed or secured to the worm wheel H driven by the worm J. The worm J is
mounted upon the shaft K which receives its motion from the driving shaft L,
carrying the worm C. The driving shaft L is provided with fast and loose belt
pulleys M M', for transmitting power from a line of shafting or direct from an
engine, although I sometimes revolve the shaft by means of a hand wheel or crank
lever. The motion of the driving shaft L is transmitted to the shaft K preferably
by chain wheels and chain M'. I form the peripheries of the discs or moulding
wheels to the configuration shown at Figure 5.
An annular space or chamber is thus formed between the interior circumference
of the cylinder A and the semi-circular periphery formed by the combined discs.
Upon one side or end of the cylinder or drum A 1 fix the double mouth piece N,
having a lower aperture N' for the admission of the lump of dough to be moulded,
and an upper aperture N2 for the discharge of the same after it has been carried
around. the interior of the drum or cylinder.
•
The discs or moulding wheels and Gare driven or revolved in opposite
directions preferably by making the worms and worm wheels right and left handed,
and by variation in the dimensions of the gearing, the disc or wheel G is caused to
revolve at a greater rate than the wheel F. The rotation of the discs causes the
lumps of dough to be rolled round and round against the interior of the cylinder
and they are thus formed into balls or spherical shapes. On reaching the
aperture N the dough balls are discharged from the machine ready for placing

page_text: together to form the loaf, cake, or other required shape. The dises or moulding
wheels may also be arranged to move in the same direction and at the same
different ratio of rotation.
or
The cylinder er drum A may be fitted with discs having different shaped edges
or peripheries so forming with the internal surfaces of the cylinder different shaped
chambers for moulding the dough. I sometimes employ a single disc or moulding
wheel having a plain periphery with side flanges as shown at Figure 6.
The cylinder may be bored out with a smooth interior in which case the whole
of the shape is given by the configuration of the edge of each disc, or it may be
formed in a series of rings or ridges to assist in giving the desired outline to the
dough. The cylinder may be used simultaneously for a number of different shaped
loaves or pieces of bread, each disc or pair of discs being arranged accordingly and
suitable apertures for filling and discharging being provided through the sides of
the cylinder opening to each dough chamber.
The cylinder may be arranged as shown at Figure 7 where the space for the loaf
is long and an adjustable ring R is provided which can be moved to different
positions by screws as S and locked in position by lock nuts as S¹. The space T
is thus made suitable for long loaves such as French loaves. Any length of loaf
may be made by adjusting properly.
Instead of arranging the grooves or recesses in the edges of the discs as small
circular recesses, I sometimes arrange within the cylinder a former or moulder of
spiral configuration and in this case each piece of dough is rolled spirally along
or through the cylinder, entering at one end and discharging towards the other
end. The discs or castings may be keyed upon the shaft in any number, and
loose rings may be driven into the cylinder to give the requisite configuration
to the cylinder at the parts forming the dough chambers.
Instead of causing the discs to revolve, the barrel, drum, or cylinder, may be
caused to revolve and the discs held stationary.
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. The method of moulding dough into shape for loaves, cakes, and like articles,
by means of discs or wheels within a hollow drum or cylinder, substantially as
herein described.
2. In dough moulding machines the use of a disc or discs or moulding wheels
having their peripheries formed for rolling the dough within a hollow drum or
cylinder substantially as and for the purposes herein before described and as
illustrated in the accompanying drawings.
3. The construction of a dough moulding machine having discs or moulding
wheels arranged for revolving in the same or opposite directions within a hollow
drum or cylinder substantially as and for the purposes hereinbefore described and
as illustrated in the accompanying drawings.
4. The improved construction and arrangement of dough moulding machines
substantially as and for the purposes herein described.
