PROVISIONAL SPECIFICATION.
Improvements in Warping Machines.
I, THOMAS SINGLETON of Bank Top Works, Darwen in the County of
Lancaster, Machinist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in warping machines and consists :-
Firstly, of improved appliances for automatically stopping the machine when an
end of yarn breaks.
Secondly, to an improved measuring motion and brake whereby the machine can
be automatically "knocked off" and stopped when any predetermined length of
yarn has passed through the machine.
The improvements render the machine less complicated and costly in its
construction.
Thirdly To improved appliances for taking up the slack yarn in the event of a
bobbin overrunning.
According to this invention and referring first to the apparatus for stopping the
machine when an end breaks, I employ oblong arched or needle eyed frames or pins
and these are preferably stamped from sheet metal and are carried on a plain or
grooved bar which extends across the machine above the pin roller, and is fixed at
each end to the "knocking off" levers, of the ordinary construction, and mounted
at their lower ends on V shaped bearings similar to scales, so as to reduce friction,
and a short arm at right angles to, and forming part of one of the knocking off
levers is provided with a regulating weight or spring so that the levers can be
balanced that only a slight pressure is required to "knock off." I dispense with
the two solid pin rollers as now employed and in lieu thereof use a roller on which
are a series of longitudinal vanes or projections, or instead of the roller I employ a
series of vanes or bars, extending the length of the machine and carried radially in
end piece The vaned roller or bars are driven from the main shaft or cylinder,
and mounted on the axis, or shaft of the knocking off levers, at right angles to
the latter is a lever which carries a toothed quadrant tumbler lever in which is
a small stud or pin. When an end breaks, and the pin or frame drops and comes
in contact with the revolving vaned roller the latter pushes back the frame and
raises the toothed quadrant tumbler lever so that the teeth in same engage with the
teeth in a spur or carrier wheel driven from the pin roller shaft wheel, and the
carrier or spur wheel causes the quadrant tumbler to turn on its axis and the pin
or stud presses against the ordinary upright notched lever, and knocks off, or
brings the machine to a stand.
The knocking off levers or handles at each end of the machine are connected by
a rod or bar extending across the machine. The ordinary square treadle rod at the
bottom of the machine is extended across same and a short lever mounted on its
end, and on this lever is a brake shoe or block to be applied to the main driving
pulley of the machine when the latter is knocked off.
The action is as follows:-The ends of yarn are threaded through the loops of
the pins, and the latter are thereby supported. In the event of one of the ends
breaking the pin falls onto the pin bar, and one of the vanes or bars of the pin
roller as it revolves comes in contact with the lower part of the pin, and forces it
backwards carrying with it the pin bar and also the knocking off levers so that the
latter turn on their V bearings and the vertical rod, thus raising the quadrant,
which engages with the teeth in the spur, or carrier wheel, which causes the

page_text: quadrant to release the vertical rod from its holding notch, and so knocks off, and
stops the machine.
When a tooth of the star wheel operates on the nug it forces it backwards and
presses the wedge shaped block against the sneck knocking off lever releases the
latter from its sneck, the treadle rises and the machine is stopped.
When the treadle rises the square bottom rod gives a part turn and moves the
break block or shoe against the main driving pulley, and so aids in bringing the
machine to a sudden stand.
The machine can be stopped by hand as ordinary and when restarted the several
parts automatically resume their normal positions.
Referring noW to the apparatus for knocking off the machine when any
predetermined length of yarn has passed through.
I employ un ordinary indicating dial and gear. In the periphery of the dial'is
cut a notch, and against the periphery the light end of a heavy ended lever rests.
The axis of the heavy ended lever is extended and terminates in a cranked finger
which rests on a second cranked finger of a tumbler lever mounted on one of the
knocking off levers, and the cranked finger of the tumbler lever is just above and
clear of the vanes or bars of the pin roller.
The action is as follows:-When the notch in the dial comes opposite to the end
of the heavy ended lever, the latter is allowed to turn slightly on its axis and this
operates the cranked finger which depresses the finger of the tumbler lever so that
it comes. opposite the vanes or bars of the pin roller, and as this revolves, one of
the vanes or bars presses against the end of the finger and forces it backwards
along with the knocking off lever so that the machine is stopped. When the notch
in the indicating dial passes the end of the heavy ended lever the parts resume
their normal position automatically.
Instead of the notch in the periphery of the dial I in some cases cut a scroll or
screw thread in the periphery of said dial and in this scroll the light end of the
heavy ended lever rests. As the dial revolves the end of the lever is gradually
moved towards the outer edge of the dial and eventually passes off the side of
same allowing the heavy end of the lever to fall, and operate the parts in the
manner herein before described.
This arrangement is suitable to machines having a falling rod.
In order to obviate having to stop the machine, in case a bobbin overruns, and
the slack allows of the possibility of the pin or frame. dropping when no end has
actually broken, I provide a strip of metal or wood extending across the machine
and forming a trough. If the attendant finds a slack end a pin or loop of metal is
placed on the slack yarn above or alongside the said trough; this counterbalances
the weight of the pin or frame and rising or falling with the yarn prevents the
frame or pin falling on the vaned roller and stopping the machine.

COMPLETE SPECIFICATION.
Improvements in Warping Machines..
I, THOMAS SINGLETON, of Bank Top Works, Darwen, in the County of
Lancaster, Machinist, do hereby declare the nature of this invention and in what
mauner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in warping machines, and consists:-
Firstly, of improved appliances for automatically stopping the machine when an
end of varn breaks.

page_text: Secondly, to an improved measuring motion and orake, whereby
be automatically "knocked off" and stopped when any predetermined length of
yarn has passed through the machine.
Thirdly, to improved appliances for taking up the slack yarn in the event of a
bobbin over-running.
Such being the nature and object of my said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which :-
is a front elevation of a warping machine having my improvements
Fig.
applied thereto.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is an end elevation of Figs. 1 and 2.
Fig. 4 is an end elevation of the opposite end of the machine to that shewn by
Fig. 3.
The remaining figs. are details drawn detached, in order to illustrate their
construction more clearly.
According to this invention and referring first to the apparatus for stopping the
machine when an end breaks, and to Figs. 1 and 2 of the annexed drawings;
employ oblong, arched, or eyed frames or pins 1. and these are preferably
stamped from sheet metal, and are carried on a plain or grooved bar 2, which
extends across the machine above the pin roller 3, and is fixed at each end to the
"knocking off" levers 4. 4 of the ordinary construction, and mounted at their lower
ends on the shaft 13 which has V shaped ends forming bearings 5 (see Fig. 4) similar
to scales so as to reduce friction. A short arm 6, at right angles to, and forming
part of one of the "knocking off" levers 4 is provided with a regulating weight 7,
or spring, so that the levers 4. 4 can be balanced that only a slight pressure is
required to "knock off." I dispense with the two solid pin rollers as now
employed, and in lieu thereof, use a roller 3 on which are a series of longitudinal
vanes or projections 8. 8; or instead of the roller 3, a series of vanes or bars 8. 8
only may be employed, these extending the length of the machine being carried
radially in end pieces such as 10. 10. The vaned roller 3, or bars 8. 8 are driven
from the main shaft or cylinder 11 by belt 12. Mounted on the axis or shaft 13
of the "knocking off" levers 4. 4, at right angles to the latter is a lever 14 (see
Fig. 3) which carries a toothed quadrant tumbler lever 15, in which is a small stud
or pin 16. When an end breaks, the pin or frame 1 supported thereby, drops, and
comes in contact with one of the vanes 8 of the revolving vaned roller 3; the latter
pushes back the frame or pin 1, levers 4. 4, and slightly turning the shaft, 13,
raises the toothed quadrant tumbler lever 15, so that the teeth in same engage with
the teeth in a spur or carrier wheel 17, driven by wheel 18 from the pin roller
shaft 3, and the carrier or spur wheel 17 causes the quadrant tumbler 15 to turn on
its axis, and the pin or stud 16 presses against the ordinary upright notched
lever 18", and "knocks off" or brings the machine to a stand.
The "knocking off" lever or handles 4. 4 at each end of the machine are
connected by the rod or bar 13 extending across the machine.
The ordinary square treadle rod 19 at the bottom of the machine is extended
across same, and a short lever 20 mounted on its end, and on this lever is a brake
shoe or block 21 (see Fig. 4) to be applied automatically to the main driving
pulley, flange or cylinder, 22 of the machine when the latter is "knocked off."
The action is as follows:-Each end of yarn is threaded through the loops or

of one of the ends breaking, the pin 1 falls onto the pin bar or roller 3, and one of
the vanes or bars 8 of the pin roller 3 as the latter revolves, comes in contact with
the lower part of the pin 1 and forces it backwards, carrying with it the pin bar.2
and also the knocking off levers 4. 4, so that the latter turn on their V bearings 5,

page_text: to bear against and to release the vertical rod or knocking off lever 18° from its
holding notch, and so "knocks off" and stops the machine.
When the treadle 24 rises, the square bottom rod 19 gives a part turn to and
moves the brake block or shoe 21 against the main driving pulley, flange, or
cylinder 22, and so aids in bringing the machine to a sudden stand.
The machine can be stopped by hand as ordinary, and when re-started, the
several parts automatically resume their normal positions.
Referring now to the apparatus for "knocking off" the machine when any
pre-determined length of yarn has passed through, and to Figs. 2 and 3 of the
drawings.
I employ an ordinary indicating dial and gear 25. In the periphery of the
dial is cut a notch 26, and against the periphery of the dial, the light end of a
heavy ended lever 27 rests. The axis 28 of the heavy ended lever 27 is extended
and terminates in a cranked finger 29 which rests on a second cranked finger 30 of
a tumbler lever 31 mounted on one of the knocking off levers 4, and the cranked
finger 30 of the tumbler lever 31 is just above and clear of the vanes or bars 8 of
the pin roller 3.
The action is as follows:-When the notch 26 in the dial comes opposite to
the end of the heavy ended lever 27, the latter is allowed to turn slightly on its
axis, and this operates the cranked finger 29, which depresses the finger 30 of
the tumbler lever 31 so that it comes opposite the vanes or bars 8 of the pin
roller 3, and as this revolves, one of the vanes or bars 8 presses against the end
of the finger 30 and forces it backward along with the knocking off lever 4, so
that the machine is stopped. When the notch 26 in the indicating dial pusses
the end of the heavy ended lever 27, the parts resume their normal position
automatically.
Instead of the notch 26 in the periphery of the dial, I in some cases cut a scroll
or screw thread in the periphery of said dial 25, and in this scroll the light end of
the heavy ended lever 27 rests. As the dial revolves, the end of the lever 27 is
gradually moved towards the outer edge of the dial and eventually passes off the
side of same, allowing the heavy end of the lever to fall and operate the parts in
the manner herein before described. This arrangement is suitable to machines
having a falling rod.
In order to obviate having to stop the machine in case a bobbin over-runs and
the slack allowing of the possibility of any of the pins or frames 1 dropping when
no end has actually broken, I provide a strap of metal or wood extending across
the machine, and forming a trough 33. If the attendant finds a slack end, a pin
or loop of metal 34 is placed on the slack yarn above or alongside the said
trough 33, this counterbalances the weight of the pin or frame 1, and rising or
falling with the yarn prevents the frame or pin 1 falling on the vaned roller 3 and
stopping the machine.
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 general construction, arrangement, and combination of parts
constituting the improved appliances for automatically stopping a warping
machine, as and for the purpose herein described, and substantially as illustrated
by Figs. 1 and 2 of the annexed drawings.
(2.) The pins or frames 1, grooved or plain bar 2, levers 4. 4, and shaft 13, all in
