Improvements in the Driving Mechanism for Operating the Guage
Rollers of Biscuit Machines.
I WILLIAM BRIERLEY of The Borough Brass Works Rochdale in the County of
Lancaster Brass Founder do hereby declare the nature of this invention to be as
follows:-
My invention relates to the mechanism for operating the gauge rollers of Biscuit
Machines, which machines are well known and which invention may be applied to
existing machines. I am aware that gauge rollers have hitherto been actuated by cone
drums and gearing, but in such machines upon the occurrence of what is known as
"backlash," there occurs an unsteady or irregular movement of the gauge rollers, the
consequence is that objectionable impressions or indentations are transferred to the
dough passing through the machine between the rollers, and known as "creasing."
Now such disfigurement or "creasing" of the dough is the sole object for which
my said invention is designed to obviate, and which is accomplished by the
following means.

At any convenient part of the Machine preferably in proximity to the gauge rollers,

I apply two drums one having a concave surface the other a convex surface;
drums are situated in a vertical position with relation to the plane of the Machine, the
concavity and the convexity of the said drums are the leading features of my inven-
tion, as the driving band (which may be moved along the surfaces of the said drums
by suitable means) adheres more closely to the surfaces thereof than would be the

cation of the concave and convex drums therewith, the surfaces of the said drums
being so formed, aid the instantaneous-action of the gauge rollers, for the driving
band when moved along the surfaces of the drums maintains a rigid or firm position
in whatever direction the strap may be moved thereon. The concavity and the con-
vexity being as before stated the essential features for the accomplishment of the

being the primary object and which regular motion obviates "creasing" of the dough

I WILLIAM BRIERLEY of the Borrough Brass Works Rochdale in the County of

manner the same is to be performed, to be particularly described and ascertained in

At any convenient part of the machine preferably in proximity to the gauge rollers,.

such drums are situated in a vertical position with relation to the plane of the machine,

Motion is first imparted to the drum having a concave surface by means of a suitable
driving band, a driving band also passes from the concave drum to the convex drum,
at the upper part of the convex drum is situated a small worm gear wheel, which gears
into a gear wheel provided on the end of the shaft of the lower gauge roller; or if
desired a train of gear wheels may be employed intervening between the convex drum
and the gear wheel on the end of the lower guage roller shaft, the surfaces of the
said drums being so formed aid the instantaneous action of the gauge rollers, for the
driving band when moved along the surfaces of the drums, maintains a rigid or firm

the object of my invention, as the steadiness or regular movement of the driven drum
being the primary object, and which regular motion obviates "creasing" of the dough
passing through the machine.
In order that my invention may be understood I have reference to the accompanying
sheet of drawings in which :-
Figure 1 represents a side view of my invention shewing so much of the frame of
the machine as is necessary to illustrate my invention.

page_text: At the lower part of the shaft of the convex drum a (which drum is driven by
means of a belt from the driving drum a¹) is situated a bevel gear wheel, b, which
gears into a gear wheel, e, on the shaft d, is provided a gear wheel, e, intervening
Between the gear wheel, e, and the gear wheel, f, I employ a train of wheels, h, i, j, k,
and 1, the wheels ; and being on shaft m and the wheels h, and i on shaft, n, the
wheel, 7, is situated on a stud, o, which stud is situated in a slotted quadrant, p, the
stud being adapted so that the same may be moved along the slot in the quadrant and
adjusted in any convenient position, by which arrangement I am enabled to provide
on the stud, o, a gear wheel of any convenient size which may be necessary in order
to impart a greater or less velocity (when motion is imparted to the drum, a,) to the
gauge roller shaft y and which may be necessary accordingly as the dough is required
to pass between tho guage rollers, and s at greater or less velocity as the case
may be.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. The combination of the conical drums a. a¹ having convex and concave surfaces
respectively and the train of wheels intervening between the convex drum a and the
gear wheel on the lower guage roller shaft 9, substantially as and for the purposes
herein fully set forth and described in the drawings hereunto annexed.
2. The use and application of the slotted quadrant provided with a moveable stud o,
substantially as and for the purposes herein fully set forth and described in the
drawings hereunto annexed.
