PROVISIONAL SPECIFICATION left by the said Edward Crossley, Louis
John Crossley, and William Sutcliffe at the Office of the Commissioners of
Patents on the 24th May 1881.
EDWARD CROSSLEY and LOUIS JOHN CROSSLEY, Carpet Manufacturers, and
WILLIAM SUTCLIFFE, Manager of the Spinning Department, all three of Halifax,
in the County of York. "IMPROVEMENTS IN SPINNING, AND IN MACHINERY OR
APPARATUS CONNECTED THEREWITH."
This Invention relates to further improvements in machinery for stopping the
progress of the roving towards the delivery rollers on the breakage or the slackening
of spun threads, for which Letters Patent were granted to us, dated the twenty
sixth day of July, one thousand eight hundred and eighty, numbered 3076.
In carrying out our present improvements we employ a rocking motion to act
on a small light lever on the front end of the weighted bent lever, by which means
we give a quick positive motion for stopping the delivery of the roving.
We employ for each spindle of a spinning frame back rollers and angular
dropping levers, as described in the Specification of our said former Letters Patent,
and also a bent lever, but instead of the end of the back arm being cut with a
screw on which screws a small weight to counterbalance the leverage the small
weight is placed near the fulcrum to allow the front arm to be more weighted,
and the weight can be shifted more or less towards the fulcrum, according to
requirements.
We fit in any convenient place in the spinning frame an eccentric shaft actuated
by a pulley and strap driven from a pulley, preferably fitted on the cylinder shaft;
the eccentric shaft extends the length of the frame, on which are fitted three or
more eccentrics, which actuate eccentric rings and levers. The ends of the eccentric

page_text: levers are secured to hanging down levers fitted on a small shaft extending the
length of the frame; the eccentrics actuate the small shaft, giving motion to
bearers secured on the shaft, and which actuates frames secured thereon, by which
means a rocking action or motion is given to the frames.
On the front of each bent lever we fix a screw, over which is passed a light wire
lever, the front wire having a bent end, over which passes the thread when
spinning; the drag of the thread keeps down the front wire, and lifts up the back
wire or lever.
On the breakage or slackening of the thread the back wire falls, and brings a
bent up end in contact with the rocking frame, which at once throws up the front
arm of the bent lever, thereby lowering the back arm, and bringing the arm in
contact with the dropping levers, at once forcing the catch or rounded end in gear
with the teeth or holes, or from the pegs of the back roller, so as to immediately
stop the delivery of the roving.
The thread passing over the bent end of the light wire lever when spinning
presses down the lever, and lifts up the back wire lever, which lowers the front
arm of the bent lever, and lifts up the back arm, removing the same from the
dropping levers, and bringing the catch or rounded end out of gear with the back
roller, allowing a free action to the back roller.

APPARATUS CONNECTED THEREWITH."
The said Invention relates to further improvements in the machinery for
stopping the progress of the roving towards the delivery rollers on the breakage or
slackening of the spun threads after leaving the delivery rollers, for which Letters
Patent were granted to us, dated the twenty sixth day of July, one thousand eight
hundred and eighty, numbered 3076.
In carrying out our present improvements we employ a rocking rail or bar con-
structed to act on a small light lever fitted to the front end of the weighted or
bent lever, which is applied to each thread in the spinning frame, and the said bent
lever we employ in our former Patent of 1880, by which means we obtain a quick
positive motion for stopping the delivery of the roving.
We employ for each thread in a spinning frame double back rollers and angular
dropping levers, similar in construction to those shown and described in the
Specification of our said former Letters Patent, and also a bent lever, but instead of
having the end of the back arm cut with a thread on which screws a small
weight to counterbalance the leverage, we place the fulcrum of the lever in such
a position as to allow the front, arm to be heavier than the back arm. We fit in
any convenient place in the spinning frame an eccentric shaft, and on which is
fitted one or more eccentrics, which actuate an eccentric ring or rings and levers;
the eccentric shaft is actuated by a spur wheel secured on the shaft, and the spur
wheel is worked by a pinion on a shaft, which is driven by a pulley on the end of
the shaft; this pulley receives its motion from a belt driven by the cylinder shaft
of the spinning frame. The eccentric or eccentrics actuate the levers at both
spinning sides of the frame, and the ends of the levers are secured by bolts and
nuts to upright levers fitted on a sinall shaft extending the length of the frame;
the eccentrics by means of the levers actuate the small shaft, giving motion to
levers secured on the shaft, which levers actuate frames or rails secured thereon,
thereby giving a rocking motion to the said frames or rails.
Near the front end of each bent lever we fit a stud, on which works the fulcrum
of a light wire lever; the front part of the wire lever is bent sideways at right
angles, and over this bent part passes the thread when spinning; the drag of the
thread keeps down the front end and lifts up the back end of the wire lever.
On the breakage or slackening of the thread the back end of the wire lever being
heavier falls and comes into contact with the rocking frame or rail, which thereupon
raises the front arm of the bent lever and lowers the back arm, so as to allow the
angular lever, which is in contact with the back arm of the bent lever, to fall and
come into gear at its top end with the teeth, pegs, or holes on the side of the back
roller, so as to immediately stop the delivery of the roving.
The thread passing over the bent end of the light wire lever when spinning
presses down the front end of the lever, and lifts up the back, which lowers the
front arm of the bent lever and lifts up the back arm, bringing the same in contact
with the dropping angular levers, and bringing the upper end out of gear with the
back top roller, allowing free action to the back roller.
But in order to enable our improvements to be better understood we will proceed
to describe the same by reference to the accompanying Drawing, which represents
a side elevation, shewing our present improvements applied to a spinning frame
constructed according to our said former improvements in the machinery for
stopping the progress of the roving towards the delivery rollers on the breakage or
slackening of spun threads.

page_text: A are brackets secured to the spinning frame B; the brackets are made with slot
holes C, through which are passed bolts for securing the brackets D, in the bearings
of which works a shaft E; on the shaft is or are fitted one or more eccentrics F,
which actuate eccentric rings G, to which are secured rods H; the shaft E is
actuated by a pinion I secured on a shaft J actuated by a pulley K worked by a
belt L driven by the shaft M of the spinning frame cylinder N; the pinion I
actuates a spur wheel O fitted and secured on the eccentric shaft E, thereby
actuating the shaft, and consequently the eccentric or eccentrics.
The eccentric F in actuating the rods H give a forward and backward action to
upright levers P, which are secured on a small shaft Q extending the length of the
frame, or the shaft may be made in several lengths if required; the levers Paro
made with slot openings R, through which are passed bolts to secure the ends of
the levers H to the levers P; the shaft Q works in bearers S bolted to the spinning
frame B; on the shaft Q are secured 'levers T, to which is fixed a frame or rail U.
which receives a to and fro or rocking motion.
The bent lever V of each spindle works on a pin W, which is secured by a
bracket X on a rail Y, and the front arm Z of the lever V is made heavier than
the back arm A¹; the lever V is also made with a stop B¹, and near the front end
is secured a stud C, on which works a light wire lever D¹; the front arm E¹ is
bent sideways at right angles, and over the bent part passes the thread F¹ when
spinning, the drag of the thread keeps the arm E' down, and consequently lifts up
the back arm or wire G¹.
On the breakage or slackening of the thread F¹ the back arm or wire G' falls,
and comes into contact with the rocking frame or rail U, which at once throws up
the front arm Z, thereby lowering the back arm A¹, removing the arm from
contact with the dropping angular levers H', allowing them to fall over into gear
with the teeth of the top roller J, so as to immediately stop the delivery of the
roving.
The thread F¹ when spinning presses down the arm E¹ and lifts up the arm or
wire G', which lowers the weighted arm Z, and lifts up the back arm A', so as to
bring the arm A' in contact with the dropping levers H¹, and the catch or
rounded end I out of gear with the rollers J¹, thereby allowing free action to the
back roller.
Having thus particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed or carried out in
practice, what we claim as new and intend to be protected by the herein in-part
recited Letters Patent is,-
The construction and employment of a rocking mechanism or motion, such as
that hereinbefore described, acting on small light levers fitted to the front ends of
the bent levers V, for the purpose of giving a quick positive motion for stopping
the delivery of the roving, as herein before described and represented in the
accompanying Drawing.
In witness whereof, I, the said Edward Crossley, for and on behalf of myself
and the said Louis John Crossley and William Sutcliffe, have hereto set
my hand and seal, this Twenty second day of November, in the year of our
Lord One thousand eight hundred and eighty one.
