PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Gauging Dough and Cutting and
Panning Biscuits.
We JOHN VICARS, THOMAS VICARS and JOHN VICARS Junior all of 29 Seel Street
Liverpool in the County of Lancaster Engineers do hereby declare the nature of this
invention to be as follows:-
The invention relates to apparatus in which sheets of dough are gauged or reduced
to a uniform and required thickness, and afferwards cut into the required shapes and
placed on pans or wires.
The main object is to enable the machines to be run at a higher speed and with
greater steadiness than heretofore.
For that purpose we drive the gauging rollers from the crank shaft which gives
motion to the levers actuating the dough cutters by means of change wheels arranged
on adjustable centres. We also connect the ratchet wheels for giving step by step or
intermittent motion to the chains carrying the pans or wires to their shafts by means
of springs, and interpose spring connections between the pans and their carriers.

Improvements in Apparatus for Gauging Dough and Cutting and
Panning Biscuits.
We JOHN VICARS, THOMAS VICARS, and JOHN VICARS, Junior, 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:-
The invention relates to apparatus in which sheets of dough are
to a uniform and required thickness, and afterwards cut into the required shapes and
guaged, or reduced
and placed on pans or wires.
The main object is to enable the machines to run at a higher speed and with greater
steadiness than heretofore.
For that purpose we drive the guaging rollers from the crank shaft, which gives
motion to the levers actuating the dough cutters, by means of change wheels arranged
on adjustable centers. We also connect the ratchet wheels for giving step by step, or
intermittent motion to the chains carrying the pans, or wires to their shafts by means
of springs and interpose spring connections between the pans and their carriers.
Figure 1. is an end elevation, Figure 2. a side elevation and Figure 3. a plan of so
much dough guaging apparatus as will be sufficient to explain the application thereto
of change wheel driving mechanism under our invention.
1. Frame of an apparatus, 2. crank shaft which gives motion to the levers which
actuate the dough cutters, 3. pinion secured on the said shaft, 4. lever fitting freely on
the end of the said shaft, 5. rack on the end of the lever 4. geared into the worm 6.,
7. worm shaft carried in bearings 8. secured to the frame 1., 9. hand wheel for giving
motion to the said shaft, 10. intermediate wheel carried by a stud on the lever 4.
geared with the pinion 3., wheel 11.,-The wheel 11. is secured on one end of a
shaft 12. which passes through a bearing on the lever 4., and is fitted at its other end
with a pinion 13. which gears into the wheel 14. carried on the shaft 15. of the lower
dough guaging roller. The upper and lower dough guaging rollers are geared together
by means of the wheels 16. The required speed of the dough guaging rollers for different
sizes of biscuits is obtained by altering the position of the lever 4. by means of the
rack 5. and worm 6. operated by the wheel 9. and substituting wheels of the requisite
diameter, for the wheels and pinion 14. 13.
Figure 4. is an elevation, and Figure 5. a plan of apparatus under our invention,
for giving step by step motion to the chains carrying the pans in apparatus for guaging,
cutting, and panning biscuits.-17. Shaft carrying the chain driving pulleys., 18. ratchet
wheel loose on the Shaft 17., 19. Arm secured to the shaft 17. 20. Spring connecting
the ratchet wheel 18., to the Arm 19., and adjusted as to tension by the eyebolts and
nuts 21., 22. paul driving gear. By the use of the apparatus above described the spring
connection prevents the sudden and jerky motion being given to the carrying chains
when the apparatus is run at a high speed.

page_text: Figure 6. is a plan of a spring pan carrier appliances under the inventions 23. chains
on which the pans rest, 24. Carrier bars secured to the chains and travelling with them,
so as to carry the pans along with the chains, 25. spring secured to the carrier 24. and
in contact with the pan being moved.-The bars are secured to the chains at the requi-
site distances apart to admit of pans resting between them on the chains.
Figure 7. is a plan of modified apparatus under this part of our invention here a
bar 26., is fitted with steady pins 27., which pass freely through holes in the carrier 24.,
28. Spiral rings surrounding the said steady pins between the bars 26. and carrier 24.
The Apparatus illustrated in figures 6. and 7. prevent the pans from being jerked
forward when rapid step by step motion is given to the chains.-The apparatus described
in figures 4. 5. 6 & 7 may be used separately or together.
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 :-
First In apparatus for guaging dough and cutting buiscuits the combination with
the driving shaft giving motion to the levers actuating the dought cutters and a shaft
of the dough guaging rollers of change wheel driving mechanism for the purpose
set forth.
Second The combination for guaging dough and cutting biscuits of the Shaft 2.,
pinion 3., lever 4., rack 5., worm and connections 6., intermediate wheel 10., wheel 11.,
and Shaft 12. 15. with change wheels 13. 14-substantially in the manner and for the
purpose set forth.
Third In apparatus for guaging dough and cutting and panning buiscuits connecting
the ratchet wheels for giving step by step motion to the chains carrying the pans to
their shafts by means of springs.
Fourth In apparatus for cutting dough and cutting and panning buiscuits., the
combinations of the shaft 17. ratchet wheel 18., Arm 19., Spring 20., eyebolts 21., and
paul driving gear 22. substantially in the manner and for the purpose set forth.
Fifth The combination with pan carriers in apparatus for guaging dough and
cutting and panning buiscuits, of springs, for the purpose set forth.
Sixth The combination in apparatus for guaging dough and cutting and panning
buiscuits of the chains 23., Carrier 24., and spring 25. substantially in the manner and
for the purpose set forth.
Seventh The combination in apparatus for guaging dough and cutting, and panning
buiscuits, of the chains 23., carrier 24., bar 20., steady pins 27. and springs 28. substan-
tially in the manner and for the purpose set forth.
Eighth The combination of apparatus for guaging dough and cutting and panning
biscuits of two or more of the several improvements herein set forth.
