APPARATUS CONNECTED THEREWITH."
Our Invention relates to fitting to spinning frames an apparatus for stopping the
progress of the roving towards the delivery rollers on the breakage or slackness of
the spun thread, preventing waste, roller lapping, snarls, and doubles.
For this purpose we make the back or feeding rollers separate, instead of employing
the double rollers where double rollers are used. The rollers are also made with
increased diameters, and by preference the top rollers are fluted. On the side of the
top roller we cast or fix a chain wheel, in the teeth of which works a link cbain
which actuates another chain wheel cast on the side of a catch wheel; the bottom
chain wheel and catch wheel work in bearings fixed in a suitable part of the spinning
frame; the link chain runs slack, allowing of shifting the back roller and altering
the ratch. The thread coming from the front rollers passes through the eye of a
centred light lever, the back arm of this lever being made with a catch; the drag
of the thread when spinning presses down through the eye of the centred light lever,
and thus keeps up the back arm having the catch and allows the link chain to travel
freely with the chain wheels; but should the thread break or become slack, or the
pressure on the eye of the light lever be removed, the back arm falls and the catch
on the arm comes in contact with a tooth of the catch wheel, stopping the wheel
and also the bottom chain wheel, which stops the motion of the link chain, roller
[Price 6d1

page_text: chain wheel, and top roller, and consequently the delivery of the roving from the
back feeding rollers, by which means we prevent waste, roller lapping, snarls, and
doubles.
We can dispense with the catch wheel into which falls the catch of the arm of the
centred lever, and we make the links of the link chain with projections, and the
catch on the centred lever falls in a projection or projections, stopping the link
chain, and consequently the top roller and delivery of the roving.
We also employ a guide, fitted near and over the rollers, causing the roving to
lap partly over the top roller, producing drag; or we fit in the spinning frame a
shaft which extends across the frame. The shaft is fixed, and on the shaft we fit
the top rollers having the chain wheels; the rollers run loose on the shaft, and are
made with recesses, in which we place felt or other suitable absorbent material to
lubricate the rollers.
We also employ an apparatus which dispenses with the chain wheels, link chains,
catch wheel, and centred levers.
For this purpose we fix or cast wheels on the single top rollers, and we fix for
each top roller a light lever or bracket, which is bolted on a support fixed under the
carrier, or fixed to the casting that carries the top roller. The top of the lever or
bracket is made with a slot hole, in which is secured a stud on which works a lever;
the back part of this lever or arm of the lever is made long, and with teeth on the
underside forming a rack; and the front arm is made short, and a long wire made
with a bent end is secured in the same. The thread, in passing to the flyer, passes
over this bent end, and the drag of the thread in spinning presses down the wire,
lifting up the back arm having the rack; but should the thread break or become
slack, and the pressure on the bent end of the wire be thereby removed, the lever
turning on its fulcrum lifts up the wire and lowers the arm having the rack, causing
a tooth or two to come in contact with a tooth or two of the wheel cast or fitted on
the top back roller, stopping the roller and delivery of the roving. The rack is
made long to allow of moving the back roller backwards or forwards, according to
the length of the staple spinning.

The said Invention relates to fitting to spinning frames an apparatus for stopping
the progress of the roving towards the delivery rollers on the breakage or slackening
of the spun thread, thereby preventing waste, roller lapping, snarls, and doubles.
For this purpose we make the back or feeding rollers separate, instead of employing
the usual double rollers, where double rollers are used. The rollers are also made
with increased diameters. On the side of the roller we cast or fix a chain wheel, in
the teeth of which works a link chain which actuates another chain wheel cast on
the side of a catch wheel; the bottom chain wheel and catch wheel work in bearings
fixed in a suitable part of the spinning frame; the link chain runs slack, allowing
the shifting of the back roller and of altering the ratch. The thread coming from
the front rollers passes through the eye of a centred light lever, the back arm of this
lever being made with a catch; the drag of the thread when spinning presses down
through the eye at the front end of the centred light lever, and thus keeps up the
back arm having the catch and allows the link chain to travel freely with the chain
wheels; but should the thread break or become slack, or the pressure on the eye of
the light lever be removed, the back arm falls and the catch on the arm comes in
contact with a tooth of the catch wheel, stopping the wheel and also the bottom
chain wlieel, which stops the motion of the link chain, roller chain wheel, and top
roller, consequently the delivery of the roving from the back feeding rollers, by which
means we prevent waste, roller lapping, snarls, and doubles.
We also employ a guide fitted near and over the rollers, causing the roving to lap
partly over the top roller, producing drag; or we fit in the spinning frame shafts
which are fixed and extend across the frame. On the shafts we fit the top rollers
having the chain wheels; the rollers run loose on the shafts, and the rollers are
made with recesses, in which we place felt or other suitable absorbent material to
lubricate the rollers.
We can dispense with the catch wheel into which falls the catch of the arm of the
centred lever, and we make the links of the link chain with projections, and the
catch on the centred lever falls in a projection or projections, stopping the link chain,
consequently the top roller and delivery of the roving.
We also construct and employ an apparatus to allow of doing away with the chain
wheels, link chains, catch wheels, and centred levers.
For this purpose we fix or cast wheels on the single top rollers, and we fix for
each top roller a light lever or bracket, which is bolted on a support fixed under
the carrier, or fixed to the casting that carries the top roller. The top of the lever
or bracket is made with a slot hole in which is secured a stud, and on which works
a lever; the back part of this lever or arm of the lever is made long, and with teeth
on the underside forming a rack, and the front arm is made short, in which is secured
a wire made with a bent end. The thread, in passing to the flyer, passes over this
bent end, and the drag of the thread in spinning presses down the wire or bent end
of the lever, lifting up the back arm having the rack. Should the thread break or
become slack, and the pressure on the bent end of the wire or lever be then removed,
the lever turning on its fulcrum lifts up the wire or bent end and lowers the arm
having the rack, causing one or more teeth to come in contact with one or more

page_text: teeth of the wheel cast or fitted on the top back roller, thus stopping the roller and
delivery of the roving. The rack is made sufficiently long to allow the moving of
the back roller backward or forward, according to the length of the staple spinning.
But in order to enable our improvements to be better understood we will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
represents a side elevation of the chain motion apparatus for stopping the progress
of the roving towards the delivery rollers on the breakage or slackening of the spun
thread; Figure 2 represents a side elevation of the rack motion for a similar purpose;
and Figure 3, plan of position of the rack levers. Similar letters of reference are
used to represent similar parts.
A, back feeding rollers, which are made separate, instead of the double rollers
usually employed where double rollers are used; the rollers A are also made withi
increased diameters and with recesses, in which is placed felt or other suitable
absorbent material to lubricate the rollers. On the side of each roller is cast or
fitted a chain wheel B, in the teeth of which works a link chain C; this chain
actuates another chain wheel D giving motion to a catch wheel E which is cast on
the side of the chain wheel. The chain wheels D fitted to the spinning frame are
fitted on a shaft or stud F which works in suitable bearings fitted to the frame; the
chain of each roller works slack, and is guided by a rod G fitted across the spinning
frame, which allows the shifting of the back rollers for altering the rack. The roving
H passes over a guide I and partly under the roller A, and between the roller J and
K, producing drag; these rollers are secured on shafts and work in bearings M
secured to the spinning frame. The thread passes on through the rollers N to the
front rollers O and P, and thence through the eye Q of a centred light lever R, the
back arm S being made with teeth. The drag of the thread when spinning presses
down through the eye Q, keeping up the arm S, allowing the chain C to travel freely
with the chain wheels B and D. Should the thread break or become slack, or the
pressure on the eye Q be removed, the arm S is caused to fall and the teeth T to
come in contact with the teeth of the catch wheel E, stopping the wheel and the
chain wheel D, also the travel of the chain C, consequently stopping the chain wheel
B and roller A, and the delivery of the roving from the back, by which means we
prevent waste, roller lapping, snarls, and doubles.
Or we may employ an apparatus whereby the catch wheel is dispensed with, and
we make the links of the link chain with projections; the teeth of the arm of the
light centred lever, on the breakage or slackening of the thread, come in contact
with these projections and stop the chain and roller A, and the delivery of the roving
from the back,
Or we also construct and employ, if desired, an apparatus for stopping the pro-
gress of the roving towards the delivery rollers on the breakage or slackening of
the thread when spinning. For this purpose we cast or fix on the side of the roller
A a catch wheel U, and on the casting V which carries the top front roller P we fix
a bracket W, to which is secured a casting X which extends across the spinning
frame. On this casting, and for each spindle, is placed a centred point Y, forming
the fulcrum of a light lever Z, having an arm A¹ made long, and with teeth B';
this arm is made long to allow of the moving of the back roller backward or forward,
according to the length of the staple spinning. To the lever Z is secured a wire C¹
having a bent end D¹. The thread, in the process of spinning, passes over the bent
end D, and the drag of the thread presses down the bent end and lever Z, lifting
up the arm A', consequently the teeth B¹ from contact with the teeth of the catch
wheel U; but should the thread break or become slack, and the pressure on the
bent end of the wire be removed, the lever turning on the centred point Y lifts up
the lever Z and lowers the arm A, causing a tooth or teeth B¹ to come in contact
with a tooth or teeth of the catch wheel U, stopping the wheel and roller A, and
the delivery of the roving.
Having thus described our improvements, and the best means we are acquainted
with for carrying the same into effect, we would have it understood that we do not

page_text: confine ourselves to the precise details shewn and described, as these may be varied
without departing from the peculiar character of the Invention, but what we do
claim is,-
Firstly. The arrangement, combination, and employment of the various parts
for stopping the roving or thread on the breakage or slackening of the same,
substantially as and for the purpose hereinbefore described and illustrated in the
accompanying Drawing.
Secondly. The employment of a link or other chain working over chain wheels
for stopping the back feeding roller and delivery of the roving, substantially as
herein before described and represented in the accompanying Drawing.
In witness whereof, I, Louis John Crossley, for and on behalf of myself and
the said Edward Crossley and William Sutcliffe, have hereunto set my hand
and seal, this Twenty seventh day of April, in the year of our Lord One
thousand eight hundred and eighty.
