I, DAVID ESPLIN THOMSON, of Gillespie Street Works, Gilmore Place,
Edinburgh, in the County of Midlothian, North Britain, Engineer, do hereby
declare the nature of this invention to be as follows :-
-
The object of this invention is to give greater equality in thickness and greater
perfection to the skin of the dough sheet, and I attain this object by providing a
better means of carrying the dough to the gauge rolls.
In carrying out my invention, an endless canvas or woollen web or travelling
band is provided to work on the table carrying the dough into the gauge rolls,
which web returns to a point close to the gauge rolls. The web is driven from the
spindle of the gauge rolls by friction, and band gearing provision being made for
a continuous variable motion based upon the motion of the

COMPLETE SPECIFICATION.
Improvement in Biscuit Cutting Machines.
I, DAVID ESPLIN THOMSON, of Gillespie Street Works, Gilmore Place,
Edinburgh, North Britain, 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 object of my invention is to give greater equality in thickness and greater
perfection to the skin of the dough sheet, and I attain this object by providing a
better means of carrying the dough to the gauge rolls.
In carrying out my invention an endless canvas or woollen web or travelling
band is provided to work on the table carrying the dough into the gauge rolls,
which web returns to a point close to the gauge rolls. The web is driven from
the spindle of the gauging rolls by friction and band gearing, provision being made
for a continuous variable motion based upon the motion of the gauge rolls.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one explanatory sheet of drawing.
A is the framework of the biscuit cutting machine. B is the lower gauging roll,
the other one not shown being underneath. The dough is brought up to the
gauging rolls by means of an endless canvas or woollen web which travels along
the table C. This endless web passes round two shafts, one shown at D and a
similar one covered by the gauge roll and not shown in the drawings. This
invention relates to the adoption of this endless web and the manner and method
of driving the same which is done from the spindle of the gauging rolls as
follows: On the spindle E of the gauging rolls there is a wheel F F which
has a flat face extending from the circumference about half way in towards the
centre. This wheel communicates motion to the shaft G by friction between
the flat face and the circumference of the wheel H. This wheel H has an
india-rubber or other suitable tire which is pressed against the flat plate of the
wheel F F. The motion of the shaft G is communicated by means of the bevel
wheels I and J to an overhanging shaft K pivoted to the framework of the
machine and from the shaft K to the shaft D by pulleys L M and a belt N.

page_text: The wheel His connected to the shaft G by a feather running along the whole
length of the shaft and a slot in the boss of the wheel so that the wheel I
may be brought nearer to or farther from the centre of the wheel F in order
to diminish or increase the speed of the shaft D as may be required. The
movement of the wheel along the shaft is accomplished by means of a fork
working in the slot which is carried by a mut P shown detached at Figure 2
working in a screwed har Q, Figures 1 and 2. The speed of the endless web
is thus entirely based on the motion of the gauge rolls,
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed. 1 declare that what I
claim is :-
In a biscuit cutting machine, the driving of the endless web carrying the dough
of the gauging rolls direct from the spindle of the gauging rolls, and the menis
for adjusting the speed of the weh, substantially as described.
Dated this 9th day of June 1891.
