PROVISIONAL SPECIFICATION.
Improvements in or Applicable to Doubling and Twisting Machinery
for Cotton or other Fibrous Substances.
We EDWARD WRIGHT WRIGLEY, Cotton Spinner, JAMES ARDERN Overlooker and
CHARLES WEIR, Overlooker all of the Greenbank Mills, Oldham, do hereby declare
the nature of our said invention to be as follows:-
"
The object of this invention is to prevent waste or snarling in case of a thread
breaking also to obviate a broken thread flying onto the thread of a neighbouring
or "catch ends." We accomplish this by the
spindle and so forming "doubles
application of a small friction wheel or pulley either solid or covered with india-
rubber or other suitable material round which wheel or pulley the yarn passes on its
way between the creel and the rollers and thus causes such wheel or pulley to revolve
in proceeding to the upper brass roller. From this latter the yarn is then guided
through the rollers as may be required. In conjunction with this small wheel or
pulley and mounted upon the back of the same bracket is a wire or other lever cranked
at its extremities so as to rest with one arm supported by or against the yarn passing
over or under the rollers so long as it remains intact but immediately upon a thread
breaking the other or weighted arm of such lever falls into contact with a projection
upon the flange or side of the small wheel or pulley and thus instantly stops the
revolution of the same.
This sudden stoppage has the effect of breaking the thread which would otherwise
continue to pass through the rollers and be made into waste, thus effectually preventing
that waste and also obviating the other defects hereinbefore mentioned.
The improvements are applicable to new or existing doubling or twisting frames,
fitted either with flyers or ring spindles.

We EDWARD WRIGHT WRIGLEY, Cotton Spinner JAMES ARDERN, Overlooker and
CHARLES WEIR, Overlooker all of the Greenbank Mills, Oldham in the County of
Lancaster do hereby declare the nature of our said 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 this invention is to prevent waste or snarling in case of a thread
breaking also to obviate a broken thread flying onto the thread of a neighbouring
spindle and so forming "doubles ог "catch ends." We accomplish this by the
application of a small friction wheel or pulley either solid or covered with india-rubber
or other suitable material round which wheel or pulley the yarn passes on its way
between the creel and the rollers and thus causes such wheel or pulley to revolve in
proceeding to the upper brass roller. From this latter the yarn is then guided through
the rollers as may be required. In conjunction with this small wheel or pulley and
mounted upon the same bracket is a wire or other lever suitably cranked so as to rest
with one arm supported by or against the yarn passing over or under the rollers so
long as it remains intact but immediately upon a thread breaking the weighted arm
of such lever falls bringing the lever into contact with a projection upon the flange
or side of the small wheel or pulley and thus instantly stopping the revolution of the
same.
The improvements are applicable to new or existing doubling or twisting frames
fitted either with flyers or ring spindles.
On the accompanying drawing Fig. 1 represents a front view Fig. 2 a side view
and Fig. 3 a plan view of so much of a doubling frame as is necessary to illustrate
our improvements which are shewn applied thereto.
In all the views a is a bracket secured to the wooden rail b and carrying upon a
stud ca small friction wheel or pulley d either solid or covered with india rubber or
other frictional material. Round this pulley the yarn or thread e as it emerges
from the trough or creel is passed and thus such pulley dis caused to revolve as the
yarn then proceeds in the usual manner being drawn round the top brass roller back
again round the glass rod g and finally between the brass rollers f and h or the
thread e after passing round the friction roller d may be passed under the bottom
roller and around the top roller in the ordinary manner in being fed down to the
flyer or ring spindle.
i is the wire or other lever mounted in the same bracket a as illustrated. The
front arm of this lever is slightly heavier than the rear arm so as to give the same a
tendency to fall and its front extremity is turned at right angles to enable it to be
supported by or to rest against the yarn passing downwards from the rollers to the
flyers or ring spindles so long as the thread remains intact. The rear arm of this same
lever is cranked at ; as illustrated so that in case of the thread breaking (and the front
arm so losing its support) the lever i tilts over as indicated by the dotted lines in

page_text: Fig. 2. In this position the cranked part j of the lever i has become raised into
contact with a pin or projection k upon the flange or side of the friction pulley d and
thus has instantly stopped the revolution of the same.
This sudden stoppage has the effect of breaking the thread which would otherwise
continue to pass through the rollers and be made into waste thus effectually preventing
that waste and also obviating the other defects hereinbefore mentioned.
It will be obvious that our improvements are equally applicable to new or existing
doubling or twisting machinery for cotton or other fibrous substances.
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The improved combination and arrangement of stopping mechanism applicable to
doubling or twisting machinery for cotton and other fibrous materials and consisting
of the friction pulley and lever mounted and operating substantially as and for the
purposes hereinbefore described and illustrated on the accompanying drawing.
