IMPROVEMENTS IN APPARATUS FOR TREATING DOUGH IN THE MANUFACTURE OF BISCUITS
Year: 1885

page_text: We THOMAS VICARS the Elder JOHN VICARS the Elder THOMAS VICARS the
younger and JOHN VICARS the younger all of 29. Seel Street Liverpool in the
County of Lancaster Engineers do hereby declare the nature of our said invention
for IMPROVEMENTS IN APPARATUS FOR TREATING DOUGH IN THE MANUFACTURE OF
BISCUITS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object is to provide combined apparatus mainly to be operated by hand for
reducing kneaded dough into sheets of uniform texture and thickness and for
cutting the said sheets of dough into the required shapes for the manufacture of
biscuits.
Fig 1 is a side elevation fig 2 a plan, and 3 a sectional detail view of apparatus
constructed in accordance with our invention a framework b table adjustable
around the centre f and held in the required position by the stay b working in
the slot c moveable table pivotted at d: e roller beneath a and b carried
by the shaft f in bearings in the frame a g spur wheel secured to the shaft f:
pinion gearing with the spur wheel g and carried by the shaft i j fly wheel
k driving handles upper roller on the shaft m carried in bearings n and geared
with the roller e through the toothed wheel 7 The said roller is free to slide in
slots o in the frame a, p screws working in nuts on the bearings n and carried in
bearings q secured to the frame a On the ends of the screws are bevil wheels r
taking into bevil wheels 8 carried on the horizontal shaft t in bearings u on the
frame a,
hand wheel 1 endless travelling band passing round the rollers 2. 3
The roller 3 is ou a shaft 4 carried in bearings 5 working in ways 6 on the frame a
7 thrust screws for giving end motion to the bearings and rollers. The roller 2 is
carried on a shaft 8 in bearings in the frame a 9 ratchet wheel on shaft 8
10 pawl carried by link 11 free to oscillate on shaft 8, 12 slot in link 11 wherein
is secured the connecting rod pin 13. 14 connecting rod coupled to the pin 13 and
to the crank 15 ou the shaft i, 16 crosshead carrying the cutters and ejecting
weight of usual or suitable construction for the biscuits and free to slide in slots 17
in the frame a 18 table below the band 1 adjusted in position by the screws 19.
20 connecting rods coupling crosshead 16 to the levers 21 The levers 21 are
pivotted to the frame a at 22 and are hinged to the connecting rod 23 which is
coupled to the crank 24 on the shaft i

page_text: The action of the apparatus is as follows:-Dough from the mixing machine is
spread on the table b the tables a and c being in the position shown and is driven
between the rollers e. Z backwards and forwards and is doubled and re-rolled until
the required homogeniety is obtained When the dough is reduced to the required
condition the tables a and b are turned on their respective pivots into the position
shown by the dotted lines The Upper Roller is then screwed down until the
2 rollers are at the required distance apart to produce a sheet of dough of the
right thickness for the biscuits-The dough is then caused to travel forward on
the endless band 1 beneath the cutter 16 The endless Band 1 receives intermittent
motion through the ratchet and pawl gear 9. 10 and the extent of the motion to
suit the size of biscuits to be cut is regulated by the position of the pin 13 in the
slot 12 Whilst the endless band is at rest and the sheet of dough stationery the
Cross head 16 and cutters descend and make the required cut by means of the lever
gear 21 When the endless bands becomes too slack it is tightened by turning the
screws 7.

It will be obvious that parts of the machine may be made in various ways and
that there is nothing new in any of the parts by themselves.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, We declare that what
we claim is
Combined apparatus for reducing dough into homogeneous sheets of the required
thickness and for cutting biscuits from the said sheets.
Second In apparatus for treating dough substantially as described the adjustable
table c.
Third In apparatus for treating dough substantially as herein set forth the
combination of the adjustible tables b and c..
