IMPROVEMENTS IN OR APPLICABLE TO MACHINES FOR WARPING IN SECTIONS
Year: 1885

page_text: I PETER JOEL LIVSEY, of 24 & 25 Queens Chambers, 5 Market Street,
Manchester, in the County of Lancaster, Consulting Engineer, do hereby declare
the nature of said invention for "IMPROVEMENTS IN OR APPLICABLE TO MACHINES
FOR WARPING IN SECTIONS," to be as follows:-
My improvements are applicable to and are or may be combined with those
improvements in machines for warping in sections described in a Provisional
Specification in my name Numbered 10,649 and dated the 28th July AD 1884
and are also applicable to other section warping machines.
Firstly. My improvements relate to arrangements and combinations for rotating
the section shaft.
This is effected by a first motion shaft in suitable bearings at a right angle to
the section shaft, upon which first motion shaft there is a friction pulley that can
slide to and fro on a key on the shaft.
This friction pulley comes between two friction discs on the section shaft, and
the shaft can be slightly moved to bring the pulley against either disc accordingly
as the section is to rotate one way or the other-The friction pulley is slided on
the first motion shaft by a clutch fork connection link jointed with an arm on a
shaft in suitable bearings which shaft has an arm connected by a link with a slide
actuated by a screw as described in my aforesaid Provisional Specification.
"
Thus the friction pulley is moved as the section fills with thread, so as to keep
the speed of winding approximately uniform by diminishing the speed of the
section shaft.
Another improvement consists in the arrangement by which the friction pulley
shaft is moved and held against either friction disc on the section shaft--This is
effected by a pulley free to rotate on a shaft or stud on a lever the fulcrum of
which is on or connected with a frame or lever for moving the friction pulley shaft
or its bearing to bring the friction pulley against either friction disc.
When the lever having the pulley is moved one way, its pulley comes against
the face of one friction disc and thus becomes an abutment or fulcrum and the
fulcrum of the lever forces the frame or lever in the opposite direction to bring the
friction pulley against the other friction disc and vice versa when the pulley on
.

page_text: the lever is forced against the other disc, the pressures thus acting endways on the
section shaft are equal and balanced and thus there is no push in either direction
in consequence of the friction driving.
The lever for the pulley is acted upon by a hand lever between which there is a
suitable connection, with a spring or other elastic arrangement or a weight or
weights and weight lever, so as to put any given amount of pressure between the
friction pulleys on the lever and shaft and the friction discs, and thus give way to
slight variations, want of correctness or "truth" between the. friction pulleys or
discs and at the same time give all the required adhesion for driving with the least
friction and wear and tear.
In some cases the friction pulley shaft has its bearings carried in arms on a
rocking shaft or fulcrum which arms also carry the lever having the friction pulley
upon it.
:
•
Secondly. My improvements consist in arrangements for counting the revolutions
of the section shaft and automatically stopping it when the desired number of
revolutions have been made.
This is accomplished by means of the screw acting upon the slide described in
my aforesaid Provisional Specification, which screw is geared up with the section
shaft.
There is a pointer from the slide which refers to an index in any suitable position
which index shows the number of revolutions of the screw and thus of the section
shaft.
There is also a wheel or disc on the screw, which is or may be the hand wheel
for turning back or adjusting the screw, and the edge of this hand wheel is also
indexed, and there is a pointer fixed on the frame referring to such index.
Thus arranged the index for the screw or slide shows the number of revolutions
of the screw and the index on the wheel or disc on the screw, the fractions of the
revolutions of the screw and thus of the section shaft and by means of the two
indexes, the number of revolutions can be readily ascertained to a fraction.
There is a lever arranged on a fulcrum or stud on the side of the framing, which
carries a slide (which is or may be the index for the screw, or this index may be
fixed on the framing).
The slide on the lever is pulled one way on the arm of the lever by a spring
against a stop, and when an adjustable part upon it comes against a pointer or
projection from the said screw slide say during the last turn of the screw before
the time for stopping, the slide is moved to bring an adjustable projection on it, to
come in the way of an adjustable projection on the index disc on the screw, which
thus moves the said lever; motion from which is conveyed to mechanism for
releasing the stop handle for the friction driving or moving a toothed or friction
driving clutch out of gear to stop the machine.
The same lever or mechanism for stopping the machine when the section shaft
has made a given number of revolutions, is also connected with or is acted upon by
the sliding adjustable weight referred to in my aforesaid Provisional Specification
should it get to either extreme of its movement and thus stop the machine (until
attended to) to prevent damage.
The mechanism above described may be varied while arranged to act sub-
stantially in the same manner.

page_text: Improvements in or Applicable to Machines for Warping
in Sections.
I PETER JOEL LIVSEY of 24 & 25 Queens Chambers, 5 Market Street,
Manchester, in the County of Lancaster, Consulting Engineer, do hereby declare
the nature of this invention and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
My improvements are applicable to and are or may be combined with those
improvements in machines for warping in sections described in a Complete Speci-
fication in my name Numbered 10,649 and dated the 28th July AD 1884 and are
also applicable to other section warping machines.
Firstly. My improvements relate to arrangements and combinations for rotating.
the section shaft.
This is effected by a first motion shaft in suitable bearings at a right angle
to the section shaft, upon which first motion shaft there is a friction pulley that
can slide to and fro on a key on the shaft.
This friction pulley comes between two friction discs on the section shaft, and
the shaft can be slightly moved to bring the pulley against either disc accordingly
as the section is to rotate one way or the other-The friction pulley is slided
on the first motion shaft by a clutch fork connection link jointed with an arm
on a shaft in suitable bearings, which shaft has an arm connected by a link or
stud with a slide actuated by a screw as described in my aforesaid Complete
Specification.
Thus the friction pulley is moved as the section fills with thread so as to keep
the speed of winding approximately uniform by diminishing the speed of the
Rection shaft.
Another improvement consists in the arrangement by which the friction pulley
shaft is moved and held against either friction disc on the section shaft.
This is effected by a pulley free to rotate on a shaft or stud on a lever, the
fulcrum of which is on, or connected with a frame or lever for moving and carrying
the friction pulley shaft or its bearing to bring the friction pulley against either
friction disc.
When the lever having the pulley is moved one way its pulley comes against
the face of one friction disc and thus becomes an abutment of fulcrum and the
fulcrum of the lever forces the frame or lever in the opposite direction to bring
the friction pulley against the other friction disc and vice versa when the pulley
on the lever is forced against the other disc the pressure thus acting endways on
the section shaft are equal and balanced and thus there is no push in either
direction in consequence of the friction driving-The lever for the pulley is acted
upon by a hand lever between which there is a suitable connection, with a spring
or other elastic arrangement or a weight or weights and weight lever, so as to put
any given amount of pressure between the friction pulleys on the lever and shaft
and the friction discs, and thus give way to slight variations, want of correctness
or "truth" between the friction pulleys or discs and at the same time give all the
required adhesion for driving with the least friction and wear and tear.
..

page_text: In some cases the friction pulley shaft has its bearings carried in arms on a
rocking shaft or fulcrum which arms also carry the lever having the friction
pulley upon it.
Secondly. My improvements consist in arrangements for counting the revolutions
of the section shaft and automatically stopping it when the desired number of
revolutions has been made.
This is accomplished by means of the screw acting upon the slide described in
my aforesaid Complete Specification, which screw is geared up with the section
shaft.
There is a pointer from the slide which refers to an index in any suitable
position which index shows the number of revolutions of the screw and thus of
the section shaft.
There is also a wheel or disc on the screw which is or may be the hand wheel
for turning back or adjusting the screw, and the edge of this hand wheel is also
indexed and there is a pointer fixed on the frame referring to such index.
Thus arranged the index for the screw or slide shows the number of revolutions
of the screw, and the index on the wheel or disc on the screw, the fractions of the
revolutions of the screw, and thus of the section shaft, and by means of the two
indexes the number of revolutions can be readily ascertained to a fraction.
There is a lever arranged on a fulcrum or stud on the side of the framing
which carries or may carry a slide (which is or may be the index for the screw
or this index may be fixed on the framing) or the lever is or may be made to
slide endways.
The lever, or the slide on the lever, is pulled one way on the arm of the lever,
by a spring or weight lever against a stop, and when an adjustable part upon it.
comes against a pointer or projection from the said screw slide say during the last
turn of the screw before the time for stopping, the slide is moved to bring an
adjustable projection on it to come in the way of an adjustable projection on the
index disc on the screw, which thus moves the said lever, motion from which is
conveyed to mechanism for releasing the stop handle for the friction driving or
moving a toothed or friction driving clutch out of gear or otherwise acting upon
mechanism to stop the machine.
The same lever or mechanism for stopping the machine when the section shaft
has made a given number of revolutions, is also connected with or is acted upon
by the sliding adjustable weight referred to in my aforesaid Complete Specification
should it get to either extreme of its movement and thus stop the machine (until
attended to) to prevent damage.
The mechanism above described may be varied while arranged to act substan-
tially in the same manner.
Fig. 1 is a longitudinal section in the line of the driving shaft, fig. 2 a front
elevation and fig. 3 a partial end or side elevation illustrating one part of my
invention. A is the framing; a the section shaft; a¹ one flange; a the other
flange, and 6× the block for the section; b the presser shaft. a³ and a* are discs
secured on the section shaft a, and as is the driving shaft.
The driving shaft a³ may be arranged in any convenient manner to be driven
by a belt working on fast and loose pulleys or it may be driven from gearing in
connection with the stop mechanism for stopping. the machine when a thread
breaks or is absent when such is used or in any other convenient manner.
One bearing of the shaft a when driven directly by a belt working on the
pulleys a is carried on a cross rail between the framing and its journal is made
loose to fit in the bearing or it is made a good fit, and a pivot a' from the bearing
is made to fit a hole in the carrying rail and is secured by a screw nut, but so as
to allow the bearing to swivel slightly to bring the friction pulley as on the shaft
against either disc a³ or a¹ as required, this friction pulley a³ when in its central
position being just clear of both discs a³ and a*.
The friction pulley as is arranged to slide upon the shaft a³ and is connected
therewith by a fixed key and key way, and its boss has a groove in which a clip

page_text: fits, jointed at a to one end of a fork in a rod a jointed at the other end to the
end of an arm pl on a shaft p in bearings on the framing, this shaft, P has an
arm p which is jointed or connected by a pin or rod with the arm g from the
slide referred to in my said Complete Specification or to a special arm g* from
the slide shown in fig. 5.
Thus arranged the friction pulley a³ is slided outwards from the shaft a as the
section fills and thus diminishes the speed of the section to keep to keep the winding
upon the section at about a uniform velocity.
The inner end of the shaft as is carried on an arm or lever q having its fulcrum
on a pin q in a bracket or casting A8 secured between the side frames.
By moving this arm or lever q to one side or the other, the friction pulley a³ is
brought against one disc a³ or the other a' and the section shaft a can thus be
rotated either way at will.
Elastic or other pressure may be applied by a screw or lever, or weight lever to
the lever q to cause it to press the friction pulley as against either disc a³ or a*.
with the required force.
To take off end pressure upon the section shaft (a) a stud q' is inserted and
secured in the lever q upon which a forked lever q³ is mounted which has bearings
in it for a pressure pulley q' on a short shaft.
The short shaft is or may be passed through forks in each prong of the forked
lever and then a bush is inserted in each for each bearing and is secured by.
a screw q which acts to draw the two jaws together to close upon the bush.
© By moving the lower end of the forked lever q³ slightly the pressure pulley is
brought against one disc and the fulcrum q' acting upon the other lever
causes
the friction pulley on the shaft a to be pressed with equal force against the other
disc (a³ or a*).
The lower end of the lever q³ is or may be acted upon by a spring or weight,
lever or screw.
Fig. 4 shows one arrangement for putting pressure upon the lever q³ by a weight
lever 9 centred upon a pin or stud (9') and having two arms q' and a pin
projecting from each arm-When the weight lever q (q³ being the weight) is in
the position shown in fig. 4 one pin in one arm q7 is pressing against the side of
the lever q³ (which is the lever q³ figs. 1 and 2) but when the weight lever q is
turned half a revolution on its fulcrum the pin in the other arm q7 of the lever
will act on the other side of the lever q³.
In figs. 1 and 2 another arrangement is shown in which there is a bell crank
lever q having its fulcrum on the end of the fulcrum pin q¹ the short arm of the
bell crank lever has a pin secured in it which fits a slot in the arm of the lever q³..
The long arm of the bell crank lever q is jointed with a rod q' the upper end
of which is jointed with a two armed lever q* on a stud r in the framing.
There is a weight lever having its fulcrum on a stud in a bracket A from
the framing, and to this lever r the lower end of a lever handle is jointed-In
this lever handle there is a stud secured for a bowl 28 which rests and can run
upon the upper edge of the two armed lever q*.
The lever handle is shown in its central position where the bowl re carried by
it will rest in the V. or hollow between the two arms q* and the weight will not
act upon either of the two arms of the lever q* except the lever handle r* is moved
from the central position either way when the weight lever r will then act to
depress one or the other arm of the two armed lever q* accordingly and thus will
force the pulleys q and a³ against the discs a³ and a*.
When the lever handle has been moved to a given extent to one side or the
other, it is latched or beld in that position-There is a bracket from the framing
which carries the axis or joint 7 of a latch or lever 78 which is of such breadth as
to be kept away from a short projection (see fig. 5) in the lever handle rª until
the latter has moved to the required extent when the latch moves towards the
lever handle by the action of a spring or by the weight of the handle * secured
to the fulcrum of the latch thus the lever or latch comes on one side of the stud

page_text: in the lever handle and holds it, until the latter is to be released which is effected
by lifting the handle rx.
When the lever handle is released the weight 2 acting upon it causes the
bowl to run down the incline edge of that arm of the two armed lever on which
it rests until the lever handle arrives at the central position in which it is shown
in fig. 2.
:
The bowl does not and need not run down suddenly but so that as the
leverage diminishes the pressure of the pulleys q' and as on the discs a³ and a' and
thus the driving friction gradually diminishes and ceases when the lever handler
is in the central position as shown.
The speed at which the bowl 26 will run from one extreme of the two armed
lever to the centre will vary with the steepness of the inclination as arranged from
the extreme ends to the centre.
The lever or handle * may be actuated from any side of the machine by
arranging connecting cords, wire, chains rods or levers attached to suitable handles
or stop rods.
The lever may be secured to a short fulcrum shaft in bearings in place of
having its fulcrum on the pin q' but to make the lever q resist the twisting strain
put upon it by the forked lever q³ there is a projection q" from the lever q which
has a bent end through which the pin q¹ passes as well as through holes in the
bracket or cross rail A³.
The projection q passes through a hole in an upright A* from the bracket or
cross rail A³ to which a bracket is secured by a bolt or bolts, this bracket carrying
a sliding pin S having a cone point at one end that enters a cone centre hole in
the end of the stud q². The cone ended pin S is forced outwards towards the stud
by a helical spring surrounding it in a cavity formed in the bracket round the pin,
but a weight lever may be used in place of the spring if desired.
When the pressure is not acting to move the pulleys a³ and q side-ways the
cone sliding pin S brings the lever q to the central position in which both pulleys
will be clear of the discs as and a but the cone ended sliding pin S gives way to
the superior pressure when the pulleys are to come against the said discs.
Fig. 5 is a side elevation and fig. 6 a plan view illustrating another part of my
invention for counting the revolutions of the section shaft and stopping the
winding after a given number of revolutions or stopping the winding should the
weight ² referred to in my said Complete Specification, move to either extreme.
This modification of my invention is supposed to be applied to that modification
described in my said Complete Specification and illustrated by figs. 1 and 3 and
other figures annexed thereunto.
b
A is the framing, a section shaft, 6 presser shaft, ² weight, g the slide, shown in
fig. 3 of my aforesaid Complete Specification.
t is a lever having its fulcrum on a stud in the frame at t¹, the hole in the lever
for the fulcrum stud is slotted horizontally to allow say a quarter of an inch of
movement in the lengthway of the horizontal arm of the levert and there is a
spring t² to act upon the lever at its fulcrum to force it in one direction until one
end of the slot comes against the fulcrum pin t¹, or a weight lever may be used in
place of the spring.
There is a descending arm t³ from the fulcrum, which then bends horizontally
and then descends further and upon the projection from the horizontal part a
weight t' is secured sufficient to counterbalance the weight of the horizontal arm t
and the descending arm t upon which there is a short projection to which comes
under a hook projection or stud t' in the framing which prevents the horizontal
arm t'from lifting too high the hook t7 also preventing the arm & from moving
sideways.
There is a slot in the arm t³ in which a pin fits in one end of a lever to having
its fulcrum to on a stud in the framing this lever 18 having one arm bent horizontally
and then downwards,

page_text: There is a projecting pin from the inner side of the weight (sec also my said
Complete Specification) near its outer end which will come against one or the
other descending arms of the levers t³ or t if the weight 2, should the weight
arrive at one extreme or the other, and thus in either case it will act to lower the.
free end of the horizontal arm of the levert the arm to descending from it then
coming upon a tail piece or lover from the joint * of the latch 78 and thus
releasing the lever bandle and stopping the machine.
The screw for moving the slide for the diagonal arm g is rotated from the
section shaft which makes a given number of revolutions to one turn of the screw,
the pitch of the screw being known, thien if there is a pointer u secured to the
slide (this is secured to the slide and is then bent to come under the web of the
framing) and a suitable index plate u¹ is secured to the frame the pointer will show
what number of revolutions the screw and the section has made from the com-
mencement of the section when the pointer would start from the zero of the index-
But to show the number of revolutions more clearly, the index might be arranged
to show the turns of the screw and a wheel or pulley on the screw, the fractions of
the rotations of the screw.
If the screw f¹ were arranged to make one revolution to say 25 turns of the
section, and the screw were one eighth of an inch pitch, then each half inch of the
index would show 100 revolutions, and each 25th part of the circumference of
the pulley if index would show one revolution of the section and the subdivisions
of the pulley, the fractions of a revolution of the section.
The pulley u is supposed to be secured on the end of the screw shaft f¹ and
its edge is supposed to be indexed, a pointer u³ secured to the frame pointing to
the index on the pulley.
To make the machine stop winding on to the section at any given number of
revolutions there is a square collar u* secured by a set screw near the end of the
arm t this collar is just clear of an adjustable projection u³ which can be secured
by a screw to the edge of the pulley u².
A little less than one revolution of the screw, before the machine is to stop the
pointer u from the slide comes in contact with a pointer u which is adjustable and
is secured upon the horizontal arm of the lever t and this slides that arm of the
lever endways against the pressure of the spring t so that the square collar u* will
be in the way of the projection u³ on the pulley u³, when it comes round and it
will thus depress that end of the lever t and thus by causing the arm 15 to press
upon the tail piece 711 stop the machine.
The screw is arranged to turn in the direction so that the projection us on the
pulley u will force down the square collar u and the inclination of the thread of
the screw when so rotating must cause the slide for the arm g to move as described
in my said Complete Specification.
It will be obvious that the movement imparted as above described to the lever t
may be conveyed in any suitable and convenient manner to any other arrangement
of stop mechanism for stopping the rotation of the section.
For instance it may act through a cord or wire upon the stop mechanism for
stopping the machine when a thread breaks when used with such machines.
The section machine cannot be stopped instantly as the bobbins from which the
threads are being drawn would over run and in setting the stop projection u³
allowance will have to be made for momentum.
Fig 7 is an elevation illustrating the application of my improved counting and
stop mechanism to machines arranged as described in my aforesaid Complete
Specification and shown therein by figs. 22 and 23.
A is the framing; a section shaft; b presser shaft; f slide on slideway Aº;
fl screw; f 10 worm wheel rotating screw; g diagonal arm and c arm actuated...
There is or may be an index plate u¹ secured to the slideway A and an index
pointer on the end of a rod u secured to the slide f.
The screw shaft f' is or may, be prolonged to the back of the machine and has
a pulley u or index wheel secured upon it..

page_text: :
:
There is a thin disc us having a projection from it, which is adjustable on the
shaft, this disc when adjusted being secured by a screw.
The projection from the disc u will act upon a finger u' secured on a shaft t in
suitable bearings on the framing-The other end of this shaft has a crank t
secured upon it the pin t* of which passes through a horizontal slot in the upper
end of a rod u arranged to slide vertically in suitable guides-The lower end of
the rod u has a bent projection u7 to come over the tail piece 711 from the releasing
latch so that when the crank pin t* moves downwards the machine is stopped-
The shaft t can slide slightly endways in its bearings, and it is drawn backwards
until the crank t' is against the bearing at that end of the shaft t by a weight
lever us on a stud u in a bracket secured to the framing; the vertical arm of the
weight lever us acting against one edge of the boss of the finger u which is thus
just held clear of the rotating projection & on the pulley or wheel u' until about
the last turn of the screw f before the number of revolutions is completed, when
a projection u* from the slide will come against an adjustable collar uⓇ upon the
shaft t and slide it end ways to bring the finger u* opposite the projection u³ 'to be
acted upon by the latter when it comes round (see fig. 9 an end view of the screw
shaft, disc us, shaft t, and finger u').
In adjusting the two modifications of counting and stop mechanism illustrated
by figs. 5 to 9 inclusive, the indexes on the pulleys u³ and index plates u¹ are both
at zero when the section begins, and when the desired length has been wound as
indicated by the measuring drum, the machine is stopped-then to stop all other
sections to he made of the same size after having made the same number of
revolutions the arm t is slided end ways, the pointer. 6 (tig. 5) is brought and
secured against the pointer at (fig. 5 and the projection u fig. 5 on the pulley.u³ is
set to depress the levert to the extent for releasing the catch 8.
In the case of the modification fig. 7 the shaft t is slided inwards to bring the
finger u opposite the projection us and, the collar u is moved upon the shaft t
and secured thereto when against the projection u* from the slide and lastly the
projection u on the disc u³ is moved round to push against the finger u' to the
required extent to release the stop mechanism.
When these adjustments are made just after the trial section has been completed
the screws f¹ (in each modification) are screwed back for a fresh section (the gear
with the section shaft being first disconnected) and the screw screwed a little
further back than to the zero of the indexes and is then screwed forward to the
zero this is to take out all the back-lash in the gear and screw so that the section
shaft a may inmediately drive the screw when the section begins to wind.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The driving of section shaft by the combination of a friction pulley on a shaft
to come between two discs on the section shaft and so as to be brought and held
in contact with either to rotate the section shaft either way as required substantially
as herein before described and illustrated by the drawings.
2. The combination of a friction pulley between two discs on the section shaft
and a pressure pulley so that when the pressure pulley is brought against one disc
the friction pulley is held against the other disc with equal pressure substantially.
as herein before described and illustrated by the drawings.

upon the discs on the section shaft substantially as hereinbefore described and

the drawings.
7. The combinations and arrangements of mechanism for counting the revolutions
of the section shaft and its mode of action for putting in action the stop mechanism
