PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Rolling Dough and Cutting and
Panning Biscuits.
We, JOHN VICARS, THOMAS VICARS, and JOHN VICARS the younger, all of 56 Seel
Street Liverpool in the County of Lancaster, Engineers, do hereby declare the nature
of this invention to be as follows:-
In apparatus for rolling dough and cutting and panning biscuits great difficulty
has hitherto been experienced in running the apparatus at a high speed, and at the
same time obtaining the required conformity of action between the parts performing
the several operations of rolling, cutting, and panning.
To obviate the above defects we under our invention apply the driving power
directly to the shaft through which the cutters are actuated and communicate motion
from the cutter driving shaft or an equivalent shaft to the dough rollers and to the
panning appliances by means of the improved mechanism hereinafter described.
To give motion to the dough rollers we employ two shafts fitted with reversed cones
geared by an adjustable belt and drive one cone shaft from the cutter driving shaft
whilst the other cone shaft drives the dough rollers; provision being made, in
addition to the adjustable belt, by means of clutch gear or step pulleys for varying
the speed of motion transmitted from the driving shaft to the cones or from the cones
to the dough rollers.
A further improvement consists in employing in combination with the cones a
screw and fork for adjusting the position of the belt.
For giving motion to the driving shaft of the panning chains and for regulating
the amount of skip or accelerated motion given to the pans we divide the rods,
connecting the driving lever to the driving and skip mechanism and couple the ends
of the said rods to oscillating arms; by means of screws and blocks or equivalent
devices, so that the ends of the said. levers may be moved to and from each other.
For regulating the time of skip or accelerated motion we connect the actuating
rod above mentioned to the skip mechanism by means of a lever a worm and a
quadrant or equivalent adjusting devices.

Improvements in Apparatus for Rolling Dough and Cutting and

We, JOHN VICARS, THOMAS VICARS, and JOHN VICARS the Younger, all of 56 Seel
Street, Liverpool, in the County of Lancaster Engineers, 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
In apparatus for rolling dough and cutting and panning biscuits great difficulty has
hitherto been experienced in running the apparatus at a high speed, and at the same
time obtaining the required conformity of action between the parts performing the

motion from the cutter driving shaft or an equivalent shaft to the dough rollers

page_text: and to the panning appliances by means of the improved mechanism bereinafter
described.
To give motion to the dough rollers we employ two shafts fitted with reversed
cones geared by an adjustable belt and drive one cone shaft from the cutter or main
driving shaft whilst the other cone shaft drives the dough rollers provision being
made in addition to the adjustable belt, by means of clutch gear or step pulleys
for varying the speed of motion transmitted from the driving shaft to the cones or
from the cones to the dough rollers.
A further improvement consists in employing in combination with the cones a screw
and fork for adjusting the position of the belt.
For giving motion to the driving shaft of the panning chains and for regulating
the amount of skip or accelerated motion given to the pans we divide the rods
connecting the driving lever to the driving and skip mechanism and couple the ends
of the said rods to oscillating arms by means of screws and blocks or equivalent

For regulating the time of skip or accelerated motion we connect the actuating rod
above mentioned to the skip mechanism by means of a lever a worm 'and a quadrant
or equivalent adjusting devices.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan of our improved gear for giving motion to dough rollers. 1 and 2
are two cones with their large and small ends in opposite directions a belt 3 connects
the said cones and the position of the belt on the cones is adjusted by means of a
sliding fork 4 to which motion is given by means of a screw and hand wheel 5.
6 main driving shaft from which the dough cutter is actuated by means of the crank 7
and suitable coupling levers and connecting rods. The cone 2 is driven from the
said shaft 6 by a belt 8 and the cone 1 gives motion to the dough roller gear 9 by
means of a belt or chain 10. The relative speeds of the main shaft 6 and dough
roller gear 9 may further be varied by means of stepped pulleys 11 and 12 on the
shaft 6 and cone 2 or the said stepped pulleys or equivalent devices may be on the
cone shaft 1 and dough roller driving gear shaft 9.
Instead of using a belt to convey motion from the cone 1 to the roller gear 9
a shaft and bevel wheels or a train of spur wheels and pinions may be used. Figs. 2
and 3 are elevations of improved mechanism for giving motion to the driving shaft
of panning chains and for regulating the time and amount of skip or accelerated
motion given to pans of biscuit panning apparatus and also for regulating the time
of skip or accelerated motion. 6 web for feeding the biscuits from the cutter to the
pans. c endless chains carrying pans. d driving shaft for the chains c. el el connecting
rods for giving motion to the said shaft by means of a ratchet or clutch i. Fig. 3
the rods e e¹ are coupled by nuts to a screw and hand wheel in a piece g free to
oscillate on a pivot h. The adjacent ends of the rods e and e¹ may be brought together
or separated so that although a to and fro motion of uniform length is imparted to e
the length of motion of e' may be varied thus allowing of the speed of rotation of the
shaft d to be varied. In fig. 3 a click or clutch j is carried on a quadrant k separate
from the main arm / to which the rod e¹ is coupled but such quadrant k is caused to
move to and fro with the arm 1 by means of a worm m carried by the arm and
geared into the quadrant. n hand wheel for actuating the screw and varying the
relative positions of the arm and quadrant so that the time of skip is varied the
amount of skip being varied by the relative adjustment of the rods e e¹.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
