EDWARD CROSSLEY, Carpet Manufacturer, SAMUEL MATTHEWS, Flax Department
Manager, and JOHN MARSDEN, Machinist, all three of Halifax, in the County of
York. "IMPROVEMENTS IN MACHINERY OR APPARATUS USED IN THE PREPARATION
OF FIBROUS SUBSTANCES FOR SPINNING."
Our Invention applies to drawing and doubling frames used in the preparation of
fibrous substances, and relates to "knocking off" or "stopping" the machine or
drawing and roving frames on the cessation or breakage of the sliver or slivers.
For this purpose we fit to the ordinary stopping motion an apparatus which
automatically causes the transfer of the driving strap from the fast on to the loose
pulley, thereby stopping the machine.
We construct the apparatus as follows:-At the back of a drawing or roving
frame we fit brackets on which are cast or fitted bearers, and in which are fixed
shafts or bearers extending across the machine. The shafts or bearers have
V grooves cast or cut the whole length. One of the shafts is fitted on the top of the
brackets, the other some distance under the top shaft or bearer and on the side of
the brackets. On the shafts or bearers under each set of drawing rollers are fitted
double levers, to which are fixed tiu sliver guides, which are made round and with
side flanges. One of the levers of each set of sliver guides is made with a pro-
jecting arm, on which is placed a balance weight secured to the desired position by

page_text: a set screw. On the centre ring or boss of the lever having the projecting
weighted arm is cast a hanging-down lever or finger for the top sliver guides,
and an upright lever or finger for the bottom sliver guides, the double levers
having other projections in the centre, which rest in the V grooves of the shafts.
The projecting pieces carry the double levers, and hold the same in position,
and prevent the levers working out of the grooves of the shafts. Between the
shafts is fitted another shaft which works in bearers cast or fitted to the brackets.
On this shaft are fitted curved rocking stops and bars carried by curved arms. The
end of the arms for the top sliver guides are curved upwards, and the arms for the
bottom sliver guides downwards; the ends of these arms and bars are dished to
receive the fingers. The sliver of the fibrous substances operated on passes from the
cans at the back of the machine over the sliver guides, through guide plates and
through the drawing rollers. The tension of the sliver brings slightly down the tin
sliver guide, bringing the hanging-down or upright finger, as the case may be, in the
centre of the bracket, allowing the stops to freely rock. On the end of the stop
shaft and on the dividing side of the apparatus is fitted a lever which hangs down.
On the end of this lever is fitted a stud, on which works an upright lever having
crossed arms. On the top of this upright lever is fitted a connecting rod, the other
end of the rod being fitted to a crank which is fixed on the end of the bottom
drawing rollers' shaft. The shaft actuates the crank and connecting rod, giving a
rocking motion to the crossed arm lever which actuates the lever of the stop shaft,
giving the rocking motion to the stop.
On the breakage or cessation of the sliver passing through any of the drawing
rollers, the tension on the sliver guide being removed, the balance weight causes
the guide to be lifted, bringing the finger of either the hanging-down or upright
fingers in the centre of the dished bar of the rocking stop, stopping the rocking of
the stop and also the stop shaft lever. The shaft of the drawing rollers still making
a few revolutions actuates the crossed arm lever to which the connecting rod is
fitted, a stud which comes in contact with a catch fitted on the end of a rod which
is connected by means of a lever to the ordinary stopping motion of the apparatus,
which automatically transfers the driving strap from the fast to the loose pulley,
stopping the machine. A spring is fitted on the other cross arm of the connecting
rod lever, and the catch of the rod is made moveable, but can only move inwards.

EDWARD CROSSLEY, Carpet Mauufacturer, SAMUEL MATTHEWS, Flax Department
Manager, and JOHN MARSDEN, Machinist, all three of Halifax, in the County of
York. "IMPROVEMENTS IN MACHINERY OR APPARATUS USED IN THE PREPARATION
OF FIBROUS SUBSTANCES FOR SPINNING."
The said Invention relates to drawing and doubling frames used in the preparation
of fibrous substances, and to "knocking off" or "stopping" the machine on
drawing and roving frames on the cessation or breakage of the sliver or slivers.
For this purpose we fit to the ordinary stopping motion an apparatus which
automatically causes the transfer of the driving strap from the fast pulley on to the
loose pulley, thereby stopping the machine.
We construct the apparatus as follows:-At the back of a drawing or roving
frame we fit brackets, on which are cast or fitted bearers, and in which are fixed
shafts or bearers extending across the machine. The shafts or bearers have
V grooves cast or cut the whole length. One of the shafts or bearers is fitted on the
top of the brackets, the other is fitted some distance under the top shaft or bearer and
on the side of the brackets. On the shafts or bearers and under each set of drawing
rollers are fitted double levers, to which are fixed the sliver guides, which are mado
round and with side flanges. One of the levers of each set of sliver guides is made
with a projecting arm on which is placed a balance weight, which is secured to the
desired position by a set screw. On the contre ring or boss of the lever having the
projecting weighted arm is cast a hanging-down lever or fringer for the top sliver
guides, and an upright lever or finger for the bottom sliver guides. The double
levers have other projections in the centre, which rest in the V grooves of the shafts.
The projecting pieces carry the double levers and hold the same in position, and
prevent the levers working out of the grooves of the shafts.
Between the shafts is fitted another shaft, which works in bearers cast or fitted to
the brackets. On this shaft are fitted curved rocking stops or bars carried by
curved arms. The ends of the arms for the top sliver guides are curved upwards,
and the arms for the bottom sliver guides downwards; the ends of these arms and
bars are dished to receive the fingers.
The slivers of the fibrous substances operated on passes from the cans at the back
of the machine over the sliver guides, through guide plates, and through the
drawing rollers. The tension of the sliver brings the tin sliver guide slightly down,
bringing the hanging-down or upright finger (as the case may be) in the centre of
the bracket, allowing the stops to freely rock. On the end of the stop shaft and on
the driving side of the apparatus is fitted a lever which hangs down. On the end
of this lever is fitted a stud on which works an upright lever having crossed arms.
On the top of this upright lever is fitted a connecting rod, the other end of the rod
boing fitted to a crank which is fixed on the end of the bottom drawing roller shaft.
The shaft actuates the crank and connecting rod, giving a rocking motion to the
crossed arm lever which actuates the lever of the stop shaft, giving the rocking
motion to the stops.
On the breakage or cessation of the sliver passing through any of the drawing
rollers, the tension on the sliver guide being removed, the balance weight causes the
guide to be lifted, bringing the finger of either the hanging-down or upright fingers
in the centre of the dished bar of the rocking stop, stopping the rocking of the stop
and also the stop shaft lever. The shaft of the drawing rollers still making a few
revolutions actuates the crossed-armed lever to which the connecting rod is fitted,
which brings forward the front arm of the crossed lever, on the end of which is
fitted a stud which comes in contact with a catch fitted on the end of a rod which
is connected by means of a lever to the ordinary stopping motion of the apparatus,

page_text: which automatically transfers the driving strap from the fast to the loose pulley,
stopping the machine. A spring is fitted on the other cross arm of the connecting
rod lever, and the catch of the rod is made movable, but can only move inwards.
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 view of our improvements, and Figure 2 a front view of the appa-
ratus fitted to one set of drawing rollers.
Similar letters of reference are used to represent similar parts.
A, brackets or frames fitted at the back of a drawing or roving frame B. The
brackets or frames are constructed with bearers C, in which are fixed shafts or
bearing shafts D and E, and which extend across the apparatus. The shafts are cut
through their whole length with V grooves F. The shaft D is fitted in the top of
the frame A, and the other shaft E some distance under and on the side of the frame.
Under each set of drawing rollers are fitted double levers G and H. The lever G
is made with a projecting arm I, on which is placed a balance weight J secured in
position by a set screw.
The bosses K of the double levers G and H are made with
curved pointed projections L, which rest in the V grooves F of the bearing shafts
D and E. The pointed projections carry the double levers and hold the same in
position, preventing the levers working out of the V grooves of the bearing shafts
D and E, also producing an easy lifting and lowering motion to the sliver guides M.
which are fixed to the double levers. The levers H. are made with levers or
fingers N; the top lever hangs down and the bottom is upright. Between the
bearing shafts D and E is fitted a shaft O, which works in bearers cast on the
frames A. On this shaft are fitted curved rocking arms P, to which are fixed
curved bars Q which act as stops for the fingers. These bars extend across the
apparatus or machine. The stops or bars for the top fingers are curved or dished
upwards, and the bars or stops of the bottom fingers are dished downwards. The
dished bars receive the fingers N on the breakage of the sliver of the fibrous sub-
stances operated on.
The fibrous substances pass from the cans at the back of the machino and over
the sliver guides M, through guide plates, and through the drawing rollers. The
tension of the sliver brings slightly down the guides M, which brings the top
fingers in the centre of the frame A and the bottom finger on the side of the frame,
which allows the free rocking of the dished bars Q¹. On the end of the shaft O
and on the driving side of the apparatus is fitted a hanging-down lever R, in the
end of which is fitted a stud S, on which works an upright lever T having cross
arms U and V. In the top of the lever T is fitted a pin or stud W, on which is
fitted one of the ends of a connecting rod X, the other end being fitted on a crank
pin of a crank Y which is fitted on the end of the drawing roller shaft Z. This
shaft actuates the connecting rod X giving a rocking motion to the cross-arm
lever T, and actuates the lever R which works tho shaft O, giving the rocking
motion to the arms P and dished bars Q. The lever R is made with a projecting
arm A', to which is attached the end of a spiral spring B₁, the other end of the
spring being fitted to the cross arm U to keep the rocking lever T in working.
position.
On the breakage or cessation of the sliver passing through any of the drawing
rollers, the tension on the guide or guides M being removed, causes (by the balance
weight or weights J) the lifting of the sliver guide or guides, bringing the finger N
or fingers in the centre of the stop bar Q, either top or bottom, as the case may be,
which stops the rocking of the bar and shaft O. The drawing roller shaft Z still
making a few revolutions actuates the lever T to which the connecting rod X is
connected, which brings forward the cross arm V, on the end of which is fitted a
stud C¹ which comes in contact with a catch D' fitted on the end of a rod E³, which
works in guides F' secured to the side of the frame A. The rod E¹ is connected to
the rod G¹ of the ordinary stopping motion of the apparatus, and which auto-
matically transfers the driving strap from the fast pulley on to the loose pulley,

page_text: stopping the apparatus. The catch D₁ works on a pin H¹, and can only move
inwards, the stop I' preventing it from working outwards.
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
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,―
The general arrangement, construction, and employment of apparatus for
"knocking off" or "stopping" on the cessation or breakage of the sliver or slivers
of drawing and roving frames which are used in the preparation of fibrous sub-
stances for spinning, substantially as and for the purpose herein-before described,
and represented in the accompanying Drawing.
In witness whereof, I, the said Samuel Matthews, for and on behalf of myself
and the said Edward Crossley and John Marsden, have hereto set my hand
and seal, this Twenty-eighth day of March, in the year of our Lord One
thousand eight hundred and seventy-nine.
