PROVISIONAL SPECIFICATION.
Improvements in Machines for Working and Moulding Dough.
I, WILLIAM FREDERICK MASON, of Birch Lane, Longsight, Manchester,
Engineer, do hereby declare the nature of this invention to be as follows:-
The improvements relate to machines for working or moulding dough, and have
for object a more ready and convenient means of working or moulding the dough
than is obtained at present.
To accomplish this and to effect my improvements, I mount upon or within a
suitable framing, a revolving table or platform, capable of being raised or lowered
by cam or other like action, in which table are formed recesses or moulds of any
desirable number, by preference, for purposes of convenience, four such moulds.
The table is mounted on a vertical shaft, and the revolving motion is of an
intermittent character. The recesses or moulds in the table are for the purpose
of receiving the dough to be moulded or worked, which operation is accomplished
by means of oscillating discs or compressors, of a character somewhat similar to
the oscillating discs or compressors described in the Specification of the Patent
granted to James Beatty and Samuel Forbes, dated September 19th 1887, and
numbered 12,657, and which oscillating discs or compressors form no portion,
per se, of this my present invention, but in combination with the revolving table
before mentioned.
In operation, the table remains stationary, with the recesses or moulds directly
underneath the oscillating discs, during such number of oscillations of the discs
aforesaid as is requisite for the proper working of the dough; when the table is
caused, by cam or like motion, to be lowered a certain distance, thus clearing the
dough in the moulds from the operation of the compressors.
The table is then revolved, to a sufficient extent to bring fresh dough, in the
alternate recesses or moulds, directly under the compressors, when the table is
again raised, and the working or moulding of the dough is repeated.
The various motions are connected with the main driving shaft of the machine,
by means of suitable gearing mechanisms; and the intermittent motion of the
revolving table may be obtained by star wheel mechanism, or other forms of inter-
mittent mechanism, either put in gear by the lowering of the table or by other means,
when such lowering takes place, as will be readily understood.
In lieu of lowering the table for the purpose of clearing the dough from the
compressors, at the time of change, the compressors themselves may be arranged to
be lifted for the same purpose; and one, two, or more compressors inay be employed
in combination with a revolving table; and the details of the mechanisms for
giving the required motion to the various parts may be varied without departing
from the peculiar character of the invention.

COMPLETE SPECIFICATION.
Improvements in Machines for Working and Moulding Dough.
I, WILLIAM FREDERICK MASON, of Birch Lane, Longsight, 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 :—
The improvements relate to machines for working or moulding dough, and have

page_text: for object a more ready and convenient means of working or moulding the dough
than is obtained at present.
To accomplish this, and to effect my improvements, I mount upon or within a
suitable framing, a revolving table or platform, capable of being raised or lowered
by cam or other like action, in or upon which table are formed recesses or
moulds of any desirable number, by preference, for purposes of convenience, four
such moulds.
The table is mounted on a vertical shaft, and the revolving motion is of an
intermittent character.
The recesses or moulds in or upon the table are for the purpose of receiving the
dough to be moulded or worked, which operation is accomplished by means of
oscillating discs or compressors, of a character somewhat similar to the oscillating
discs or compressors described in the Specification of the Patent granted to James
Beatty and Samuel Forbes, dated September 19th 1887 and numbered 12,657, and
which oscillating discs or compressors form no portion, per se, of this my present
invention, but in combination with the revolving table before mentioned.
In operation, the table remains stationary, with the corresponding recesses or
moulds directly underneath the oscillating discs, during such number of oscillations
of the discs aforesaid as is requisite for the proper working of the dough, when the
table is caused, by cam or like motion, to be lowered a certain distance, thus
clearing the dough in the moulds from the operation of the compressors. The table
is then revolved to a sufficient extent to bring fresh dough, in the alternate recesses
or moulds, directly under the compressors, when the table is again raised, and the
working or moulding of the dough is repeated.
The various motions are connected with the main driving shaft of the machine,
by means of suitable gearing mechanisms; and the intermittent motion of the
revolving table may be obtained by star wheel mechanism, or other forms of inter-
mittent mechanism, either put in gear by the lowering of the table or by other
means, when such lowering takes place, as will be readily understood.
But that the invention may be better understood, I will, with the aid of the
accompanying drawings procood more fully to dosoriko moans omilaved by me

page_text: The lowering, turning and raising of the table or platform are automatically
accomplished in the following manner:
The worm e. upon the main shaft of the machine, communicates motion to the
worm wheel, on the vertical spindle, which, at it's lower extremity has attached
to it the toothed wheel. This toothed wheel engages with a corresponding
toothed wheel ', upon the intermediate spindle g. and thus motion is communicated
to the single toothed wheel g², which, once in a revolution, drives round the star
wheel or quadrant h. attached to the spindle 2, a quarter of a revolution, the
period between each of these partial revolutions being determined by the gearing,
according to the length of time required for the working of the dough in each set
of moulds.
The bowl, attached to the spindle 6263, is caused to bear the weight of such
spindle, and of the table or platform upon the surface of the cam 7. ., so that when
the table and spindle are moved round the quarter of a circle, as described, the
bowl seeks a lower level of the incline upon such cam surface, and the table is
lowered.
At the same time, the cam l. 1. has continuous motion through the gear wheels ¹¹
and g³ ³, and, as it turns, presses underneath the bowl, and gradually forces the
table up to it's former or working height, afterwards presenting a level surface to
the bowl until the next lowering operation takes place, when an inclined surface
again comes into play.
As a modification of my improvements, the intermittent circular movement of
the revolving table may be arranged to be of a reciprocatory, or to and fro
character, instead of a rotary movement in one direction, in which case a modified.
form of cam or cam actuating apparatus, or both, may be employed.
Also, in lieu of lowering the table for the purpose of clearing the dough from
the compressors, at the time of change, the compressors themselves may be arranged
to be lifted for the same purpose, and one, two, or more compressors may be
employed in combination with a revolving table, and the details of the mechanisms
for giving the required motion to the various parts may be varied without departing
from the peculiar character of the invention.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In machines for working and moulding dough, the employment of a table or
platform, provided with a number of moulds or recesses in or upon or attached to
it's working surface, and capable of revolving, or partially revolving, and rising
and falling, for the purpose and in manner substantially as herein shewn and
described.
2. In machines for working and moulding dough, the combination of a revolving
table with oscillating discs or compressors, for the purpose and in manner substantially
as herein shewn and described.
3. In machines for working and moulding dough, the combination of apparatus,
for the purpose and in manner substantially as herein shewn and described.
