page_text: PROVISIONAL SPECIFICATION,
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:-
In machines for warping yarns or threads in sections, a standard section is first
made, and then the object is to make the other sections which are to form the
complete warp as nearly the same as possible, that is, with the same length of
thread wound in the same diameters.
In some machines the sections are made on separate blocks, and are then put
together side by side on the same axis or beam to form the complete warp; in
other machines they are warped in successive sections side by side directly on the
same beam or axis; my improvements are applicable to both classes of section
warping machines.
My invention has for its object the following arrangements, namely, mechanism
for pressing and guaging the sections as they are being wound, other mechanism
which will have motion imparted to it by the machine, so as to progress at the
same speed, and represent the standard section, and which latter mechanism com-
bined with the former will indicate during the progress of the warping whether
the section being wound is in defect or excess of the standard, and this will enable
the attendant to alter the friction or tension upon the yarn or threads or weight
upon the presser to correct the excess or defect accordingly.
The further object of my invention is arrangements by which the indicator.
mechanism above referred to, is made to automatically act to change the tension or
weight upon the presser to make the correction above mentioned.
The objects of my invention may be carried out by various arrangements of
mechanism, but those arrangements which I at present prefer are hereinafter
described, parts of which may be used alone with advantage in section warping
machines without using the other parts.
I arrange any desired construction of presser or surface to act upon the threads.
as they are being wound upon the section so as to move to and from the section in
a radial line from its axis or thereabouts in guides or slides the presser being

connected with an arm from a shaft or the presser is jointed on an arm from a shaft
and is kept in or about a radial line by jointing one end of a rod to a stem from
the presser the other end of the rod being centred on a stud on the frame or on a
bracket.
On the presser shaft a lever is secured, and another corresponding lever of the
same length is centred loose on the said shaft.
"
The end of each lever has one end of a rod jointed to it, and both these rods
are of the same length and their other ends are jointed, together-As the "section."
fills with thread the lever secured upen the presser shaft moves correspondingly
one way and the other lever is actuated by motion from the section shaft in the
opposite direction so that as long as the section being wound is correct the centre
of the joint of the two rods descends in a straight vertical line half way between
the two levers, but if the section fills faster or slower than it should according to
the standard the joint of the two rods will move to one or the other side of the
vertical centre line half way between, the two levers.
A middle lever centred loose on the presser shaft comes against the joint of the
two rods and as it is kept against the said joint by a weight on an arm from it
the upper end of this middle lever moves to and fro as the joint of the two rods
changes in position.
A lever or indicator arm, centred in a bracket on the frame has a short arm to
come against the middle lever and thus the least motion is multiplied to any
desired extent.
There is an' horizontal slide carried in slideways on the framing, and this slide
has a descending diagonal arm or slideway for another slide, both the horizontal
and diagonal slides are actuated by screws-The screw for the horizontal slide. is
rotated by a ratchet and pawl worked by an excentric on the shaft rotating the
section, or this screw is continually rotated by gearing from the section shaft.
There is an arm from the diagonal slide which acts upon the lever loose upon the
presser shaft to move it as the section fills, and the screw on the diagonal slide is
to adjust the arm from the diagonal slide up and down the lever it acts upon,
to cause that lever to make exactly the same arc of movement from the vertical
centre line, as the first lever when the standard section is wound, so that when the
standard section made the fast and loose levers are both made to make exactly.
the same are of movement but in opposite directions.
When the indicator mechanism is to make corrections automatically by increasing
or decreasing the weight on the presser, a lever is fixed on the presser shaft with
an adjustable weight upon it, this weight being moved to and fro by a screw, and
the screw is rotated by a bevel wheel which gears with one loose on a stud in the
axis of the presser shaft upon the boss of which there is another bevel wheel which
gears with one loose on a stud on a lever oscillating on the said stud which gears
with another equal bevel wheel loose on the stud and secured upon the boss of
which there are two reversed ratchet wheels.
On a stud carried on a bracket above the ratchets there is a pawl jointed for
each ratchet, and upon the same stud there is a short lever that acts upon tails
from the pawls.
This short lever is connected with the indicator arm and when it moves one way
one pawl is brought into gear and when the other way the other pawl is brought
into gear with its ratchet. The oscillating lever having the bevel wheel upon it is
worked from a crank or excentric on the section shaft and when one ratchet pawl
is in gear the weight screw is turned one way and when the other ratchet pawl is
in gear the weight screw is turned the reverse way and when neither ratchet pawl
is in gear the oscillations do not act to rotate the weight screw.
When the indicator mechanism is to make corrections in the winding of the
section by varying the tension upon the threads, motion is conveyed.from the bevel
wheel upon the stud in the end of the presser shaft to the tension varying shaft to
rotate it backward and forward as required.

on the presser shaft is applicable for that system of warping sections where the
warp threads as they wind on the section are confined to, and compelled to wind
on in a given space, the presser being moved by the machine to give the space as
the section is being wound-With the modification above referred to the presser is
may be actuated and adjusted for each standard section without calculations
or change wheels, by the adjusting screw for the diagonal slide.

I do not confine myself to the above described mechanism, as it may be varied
while acting substantially in the same manner.

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 and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
In machines for warping yarns or threads in sections, a standard section is first
made, and then the object is to make the other sections which are to form the
complete warp as nearly the same as possible, that is, with the same length of
thread wound in the same diameters.
In some machines the sections are made on separate blocks, and are then put
together side by side on the same axis or beam to form the complete warp; in
other machines they are warped in successive sections side by side, directly on the
same beam or axis; my improvements are applicable to both classes of section
warping machines.
My invention has for its object the following arrangements, namely, mechanism
for pressing and guaging the sections as they are being wound, other mechanism
which will have motion imparted to it by the machine, so as to progress at the
same speed and represent the standard section, and which latter mechanism com-
bined with the former will indicate during the progress of the warping whether
the section being wound is in defect or excess of the standard and this will enable
the attendant to alter the friction or tension upon the yarn or threads or weight
upon the presser to correct the excess or defect accordingly.
The further object of my invention is arrangements by which the indicator
mechanism above referred to, is made to automatically act to change the tension or
weight upon the presser to make the correction above mentioned.
The objects of my invention may be carried out by various arrangements of
mechanism, but those arrangements which I at present prefer are hereinafter
described, parts of which may be used alone with advantage in section warping
machine without using the other parts.
I arrange any desired construction of presser or surface to act upon the threads
as they are being wound upon the section so as to move to and from the section in
a radial line from its axis or thereabouts in guides or slides, the presser being
connected with an arm from a shaft, or the presser is jointed on an arm from
a shaft and is kept in or about a radial line by jointing one end of a rod to a
stem from the presser or presser carrier, the other end of the rod being centred on
a stud on the frame or on a bracket.
On the presser shaft a lever is secured and another corresponding lever of the
same length is centred loose on the said shaft.
The end of each lever has one end of a rod jointed to it, and both these rods are
of the same length and their other ends are jointed together-As the "section"
fills with thread the lever secured upon the presser shaft moves correspondingly
one way, and the other lever is actuated by motion from the section shaft in the

page_text: opposite direction, so that as long as the section being wound is correct the
centre of the joint of the two rods descends in a straight vertical line half way
between the two levers, but if the section fills faster or slower than it should
according to the standard the joint of the two rods will move to one or the other
side of the vertical centre line halfway between the two levers.
A middle lever centred loose on the presser shaft comes against the joint of the
two rods and as it is kept against the said joint by a weight on an arm from it,
the upper end of this middle lever moves to and fro as the joint of the two rods
changes in position.
A lever or indicator arm, centred in a bracket on the frame has a short arm to
come against the middle lever and thus the least motion is multiplied to any
desired extent.
There is an horizontal slide carried in slideways on the framing, and this slide
has a descending diagonal arm or slideway for another slide, both the horizontal
and diagonal slides are actuated by screws-The screw for the horizontal slide is
rotated by a ratchet and pawl worked by an excentric or cam on the shaft rotating
the section, or this screw is continually rotated by gearing from the section shaft.
There is an arm or projection from the diagonal slide which acts upon the lever
loose upon the presser shaft to move it as the section fills, and the screw on the
diagonal slideway or arm is to adjust the arm or slide from the diagonal slideway
or arm up and down the loose lever which it acts upon to cause that lever to make
exactly the same arc of movement from the vertical centre line as the fast lever
when the standard section is wound, so that when the standard section is made
the fast and loose levers are both made to make exactly the same arc of movement
but in opposite directions.
When the indicator mechanism is to make corrections automatically by increasing.
or decreasing the weight on the presser, a lever is fixed on the presser shaft with
an adjustable weight upon it, this weight being moved to and fro by a screw, and
the screw is rotated by a bevel wheel which gears with one loose on a stud in the
axis of the presser shaft upon the boss of which there is another bevel wheel
which gears with one loose on ȧ stud on a lever oscillating on the said stud which
gears with another equal bevel wheel loose on the stud and secured upon the boss
of which there are two reversed ratchet wheels.
On a stud carried on a bracket above the ratchets there is a pawl jointed for
each ratchet, and upon the same stud there is a short lever that acts upon tails
from the pawls.
This, short lever is connected with the indicator arm, and when it moves one
way, one pawl is brought into gear, and when the other way the other pawl is
brought into gear with its ratchet.
.
The oscillating lever having the bevel wheel upon it is worked from a crank or
excentric on the section shaft and when one ratchet pawl is in gear the weight
screw is turned one way and when the other ratchet pawl is in gear the weight
screw is turned the reverse way, and when neither ratchet. pawl is in gear the
oscillations do not act to rotate the weight screw.
When the indicator mechanism is to make corrections in the winding of the
section by varying the tension upon the threads, motion is conveyed from the bevel
wheel upon the stud in the end of the presser shaft to the tension varying shaft to
rotate it backward and forward as required.
A modification of the horizontal and diagonal slides combined with a lever fast
on the presser shaft is applicable for that system of warping sections where the
warp threads as they wind on the section are confined to, and compelled to wind
on in a given space, the presser being moved by the machine to give the space as
the section is being wound-With the modification above referred to the presser is
or may be actuated and adjusted for each standard section without calculations
or change wheels by the adjusting screw for the diagonal slide.
I do not confine myself to the above described mechanism, as it may be varied
while acting substantially in the same manner..

Only such parts of a section warping machine as are necessary to explain my
invention are shown in the drawings.
The ordinary arrangement of gearing for rotating the section shaft is or may be
used, or that arrangement may be used described in a Provisional Specification
filed by myself Numbered 1877 and dated the 11th day of February 1885.
a is the section shaft, which is or may be in bearings in two end frames A so
that one end of the shaft a overhangs one of the sides frames as shown in fig 1, in
the ordinary manner. a¹ is the fixed section flange, and a the moveable flange,
and 6x is the.block upon which the yarns or threads are wound or warped.
The presser carrier 6' is or may be arranged to move to and from the section
block 6x in suitable guidés; in a radial line from the axis of the section shaft a,
but by preference it is arranged as shown in fig 2-An arm 62 is or may be secured
on the presser shaft band one end of. it is jointed to the presser carrier b¹, and
to the lower end of the latter one end of a radius link 63 is jointed the other end of
which is jointed on a stud b in a bracket A¹ secured to the framing.
The presser carrier 61 may be formed to support any suitable presser, by
preference, a flat plate 65 as shown which can be readily changed from one suited
to any desired width of section-This flat plate bo is or may be made to extend on
each side of the presser carrier b¹ and kept central by pins 66 coming into
notches in the turned down edges of the presser plate 6º.
•
The arm b² is or may be fixed in any desired position on the presser shaft b to
make it come opposite the presser carrier b' when changed to suit different widths

page_text: of sections, and loose collars 67 of the desired width are or may be used for this
purpose on the pressér shaft b and corresponding collars 6s on the stud b* for the
radius link b³.
:
:
I prefer to secure a horn or collar with a projecting finger on the presser
shaft band to leave the arm 62 loose on the shaft, but secured from moving end-
ways by an adjustable collar 610 and to form a projection upon. the arm b² for a set
screw 611 the end of which, can be screwed against the finger or part projection b
from the collar secured on the presser shaft.
This arrangement permits of the adjustment of the presser 65 to the section 6*
without altering the adjustment, when once set, of the levers hereinafter referred to.
Other arrangements in place of the set screw for adjusting the presser bo to the
section may be used if desired.
On the presser shaft ba lever è is secured, to the end of which a link c' is
jointed, and to this link c¹ one end of another link of the same length is jointed,
which at its lower end is jointed with the end of another lever d of the same
length as the lever c, the lever d being loose on the presser shaft b. This lever d
has or may have an arm d² for a weight to partly. counter-balance the weight of
the lever d and connected parts.
The lever d has a projection from it one edge d³ of which as will be seen by
reference to fig 7 is in the radial centre line of the lever c.
Between the levers c and d there is another lever e-loose on the presser shaft b
this lever e is shaped as shown in fig 7 so that the edge e which comes against the
joint of the two links c and d will be in a straight line parallel to a centre 'line
vertical to or radial from the axis of the presser shaft b-This middle lever e las
an arm e² for a weight to act upon to keep the edge of the lever c¹ pressed against
the joint of the two links c¹ and d².
In one end frame A a slideway is formed for a slide f, which is actuated by a
screw shaft f' in suitable bearings on the framing.
The screw shaft screws through screw nuts or threads formed in the slide f
The front end of the shaft f¹ has a hand wheel f2 upon it for adjusting or turning
or screwing back the screw after a section has been made On the screw shaft
there are two connected bevel wheels f³ that are arranged to slide on a key on the
shaft and there is a groove in the boss between the bevel wheels for a pin
formed on a boss on a short shaft f in bearings in the framing the pin is excentric
to the shaft f and by oscillating the latter by the handle fo the bevel wheels are
moved to bring one or the other into gear, with the driving bevel and hold it in
gear or hold both bevels out of gear when required.
The handle f is or may be held, in either extreme or its middle position by a
pin fo with a cone point passing through a hole in the lever handle f" the cone
point being pressed towards the holes in the side frame formed for it by a flat
spring foue end of which is secured to the boss of the lever f³.
This arrangement holds the hand lever f with sufficient force in any of the
three positions the cone point giving way when sufficient pressure is applied to the
handle.
The bevel wheel-f8 driving the bevels on the screw shaft is on the upper end of a
vertical shaft in suitable bearings in the side frame, there being also à bevel
wheel on the lower part of the vertical shaft f° in gear with one on a horizontal
shaft f* in bearings in the side frame and in a bracket secured thereto.
The end of the horizontal shaft fx has a worm wheel f10 (shown in dotted line
in fig 1) upon it which gears with a worm fll on the section shaft a-The gearing
between the section shaft a and screw shaft f' may be arranged in any other con-
venient manner-The sliding bevel wheels f³ permit of the section _shaft being
rotated in either direction while the screw shaft f¹ is always rotated in the same
direction when the section is being filled with yarn or thread-In some cases the
handle for turning back or adjusting the screw shaft f may be fixed on the
horizontal shaft fx in which case the worm wheel-f10 is arranged to slide on a key
on the shaft f* out of gear with the worm on the section shaft while the shaft

page_text: is being adjusted after which the worm wheel and worm are again brought into
gear. When the worm is on the side face of a disc as in figs 1 and 3 the worm
disc is or may be slided on a key on the shaft a to make the adjustment. The
slide is horizontal or at a tangent to a line radial from the presser shaft b half-
way between the two levers c and d when at their nearest positions. The slide f.
has an oblique arm g or slide way which in direction exactly coincides with a line
radial from the presser shaft forming the radial centre line of the lever c and also
the line coinciding with the edge d³ of the part from the lever d. The levers c
and d are in the positions shown in full line in fig 3 and fig 7, at the commence-
ment of the section, that is, equidistant from the radial centre line between the
two levers c and d and the slidef is screwed back to exactly the same position for
the commencement of each section, this point being fixed by the end of an
adjusting screw h against which the slide f comes when fully back.
The oblique slideway g has a screw g¹ in it in suitable bearings which screws
through a nut having a pivot g³ that screws into a slide g³ there being another pivot
on the screw nut by which the cap g is secured against the oblique arm g by a
screw nut. There is a swivel block g' on the end of the pivot g2 coming through
the slide g³ and the ledge of the swivel block g³ comes against the edge d³ of the
projection from the lever d. The weights on the weight arms of the levers d and e
keep the edge d³ of the projection close against the ledge on the swivel block g in
every position of the slide f
It will now be seen that when the section begins to fill with yarn or thread,
that the fast lever c, will move one way with the presser shaft b and the loose
lever d will be moved the other way by the slide f, and swivel block g* carried by
the oblique arm g. The speed at which the lever d has to be moved to represent
the standard section, is adjusted by screwing the slide g³ up or down the oblique
arm g as required by the screw g¹.
If both levers c and d move at the same speed during the warping of the section,
the joint of the two links c¹ and d descends in the same radial centre line from the
presser shaft b, but if one exceeds the other in speed then the joint of the two links
moves to one or the other side accordingly and the middle lever e follows such
movements. There is a bracket A² on the framing which carries a fixed and an
adjustable cone centre (see figs 1, 3, and 4) for a shaft i which has an arm i¹ at
one end, having a stud in it that comes against one edge of the top part of the
middle lever.e as shown-The shaft i has also an arm upon it for a weight 2³
which thus causes the stud 22 to be pressed against the top part of the middle
lever e,
There is a long indicator arm ; also secured on this shaft i so that by
means of a finger or pointer 71 carried on any suitable bracket it may be seen when
the indicator arm is in the true central position. This indicator arm; will thus
show when there is any deviation either in excess or defect in the section being
filled.
When a trial or standard section is being made and before it is removed when
finished the mechanism is adjusted to make similar sections by simply screwing by
means of the screw g¹ the slide on the oblique arm 9 up or down as required to
bring the indicator arm j into its central position with a mark upon it opposite the
pointer.
When making the sections, the indicator arm ; will show when the weight or
tension which ever is used is to be increased or decreased, to correct the excess or
defect in the section.
I prefer arrangements by which the weight or pressure, acting on the section can
be readily increased or diminished.
For this purpose a lever k is secured on the end of the presser shaft b, having a
screw k¹ in suitable bearings (see fig 3) and upon the arm of the lever a weight l
is arranged capable of sliding to and fro on the arm the screw k¹ passing through
a screw nut placed in a hole in the weight k².
For altering the position of the weight upon the arm or lever by the action of
the indicator arm f the following arrangement of mechanism is employed.

page_text: A Stud
is screwed into the centre of the presser shaft b'at one end (see figs 1,
3, 4, 8, 9 and 10)-On this stud there is a bevel wheel loose thereon that gears
with a bevel wheel 5 secured on the end of the screw shaft for the weight-Upon
the boss of the bevel wheel k another bevel wheel k* is secured that gears with
one 6 on a pin or stud.secured in the boss of a lever that can oscillate on the
stud . The bevel wheel ko gears with one 8 also loose on the stud k³ upon the
boss of which two fine ratchet toothed wheels k are secured the inclination of
the teeth of one ratchet being reverse to those of the other ratchet.
There is a bracket A³ secured to the framing the end of which fits upon the
stud and it has an upward projection that carries a stud l' for two ratchet
pawls each pawl having an upward arm, and one pawl being reversed to the other
to correspond with the ratchet wheel upon which it is to act-On the same stud
there is a lever 1 (see detached views figs 11 and 12) that comes between the two
pawls, and this lever 12 has a slot for a pin or stud ja in the end of the indicator
arm j so that the latter, and lever 12 will move together. From each side of
the lever there is a projection to hold an adjusting set screw 1³ the end of each
screw coming against the arm of its pawl. The object of these screws 13 is to
adjust the pawls so that when the indicator arm f is in its central position the
points of both ratchet pawls Z will be just clear of the teeth of their respective
ratchets so that should the indicator arm f move one way or the other from the
central position one pawl or the other will engage with the teeth of its respective
ratchet and thus prevent it from moving in one direction.
The arm is jointed to a rod 10 connected with a crank pin k¹¹ on the end of
the section shaft (see figs 1 and 3) so that the arm is oscillated to and fro,
consequently the bevel wheel 6.
The friction of the screw ¹ in the weight and in its bearings, causes the
bevel wheel to remain stationary while the bevel wheel is rocking and giving
oscillating motion to the bevel wheel 8 and the ratchet wheels kc secured upon its
boss.
But if the indicator arm ; moves from the central position' one of the pawls
enters the teeth of one of the ratchets and prevents it from moving one way
consequently the oscillating motion is then transmitted to the screw shaft k¹ and
will continue to be so transmitted as long as that pawl remains upon the ratchet.
The screw thread of the screw k¹ is arranged to screw the weight 2 from the
presser shaft b to give more weight, when the section is in excess, and vice versa
when in defect.
Figs 13 to 18 inclusive illustrate an arrangement of friction pawls which are or
may be when required substituted for the ratchet pawls l.
In this case in place of toothed ratchet wheels, plain wheels or pulleys are
used is the lever, it has two arms and projections to carry adjusting screws (³ to
act upon the weighted tails of the friction pawls l.
The face of each of these pawls that comes against the edge of the pulleys ³ is
excentric as shown to the axis upon which the pawls are jointed.
The weighted arm * of each acts to move the pawl to bring its excentric face
clear of the edge of the pulley k³, the object of the screws 3 being to bring the
surfaces of the pawls just clear of the surfaces of the pulleys k³ when the lever /² is.
in the central position.
$
If the lever 2 moves to one side then one pawl comes in contact with its pulley
and the motion of the pulley when moving one way will cause it to bite upon and
arrest the pulley, the weight end 1x of the pawl when so acted upon lifting away.
from the point of the adjusting screw 1³.
When motion acts upon the pulley ³ the reverse way the pawl is moved back so
as to allow the pulley to pass unobstructed.
With the arrangements described, no strain whatever is brought upon the
indicator arm and the.latter is free from restraint because the pawls are liberated
at each oscillation of the arm or lever .

page_text: •
The indicator arm j only needs to move a little to one side or the other to bring
the ratchet or friction pawls into action, and to prevent unnecessary movement
there is a projection A from the bracket A2 against which the stud i³ will come
when the latter has moved to a sufficient extent in that direction.
In figs 1 and 3 the worm wheel 10 is supposed to be driven by a worm on the
section shaft a formed upon the side face of a disc f" secured upon the section
shaft.
When a trial or standard section is to be made, the weight is screwed to about
the middle part of the lever and the end of the connecting rod 10 is detached
from the crank pin
When the weight is in the middle of the lever k it should give the required
pressure upon the section, and if not sufficient loose weights are added on the
pins in the weight these loose weights being of equal amount by preference.
While the standard section is being made or when it is finished the screw g¹ is
adjusted to bring the slide up or down to cause the indicator j 'to come into the
central position and when this has been adjusted the connecting rod 10 is attached
to the crank pin k¹¹ and the machine is ready. Should the weight ² be moved to
either extreme of the lever k in working, weight is added if the weight has been
moved to the end furthest from the axis b and removed if in the contrary
direction.
If the loose weights are of equal weights it can be ascertained by a trial how
much the weight has to be moved either way in turns of the screw upon the
lever to be approximately equivalent to an added or removed loose weight.
For instance, when the weight is say in the middle of the lever k, then
temporarily suspend weight enough to the presser carrier 6¹ to exactly balance it,
then suspend also one of the loose weights also upon the presser carrier, and screw
the weight on the lever / outwards to counterbalance it, and the number of turns
of the screw to balance the added weight will show its equivalent in leverage near
enough.
Thus when a weight is added when making sections, screw back the weight on
the lever towards the presser shaft to an extent of its equivalent, and, when a
corresponding weight is removed, screw the weight the reverse way upon the
lever k.
In some section warping machines there is a shaft in suitable bearings carrying
a bar, the warp threads going to the section pass under the bar, and over its shaft,
or otherwise, so that by rotating the shaft in its bearings, more or less friction and
thus tension is or can be given to the threads. The shaft is or may be turned by a
worm wheel on the shaft gearing into a worm on a shaft in suitable bearings and
this worm shaft is or may be automatically adjusted by gearing the same with the
bevel wheel or one in gear with it in any convenient manner, and thus the
warping of the section may be adjusted by either of the two methods or both.
Figs 19, 20 and 21 illustrate another mode of constructing and arranging the
slide fand oblique arni or slideway g.
"A bar A is formed with dove tail slides and with two ends to be secured by
screws to the side of the frame A-The oblique arm g is arranged in the line of
the lever c and projection d³ as hereinbefore described in reference to figs 3'and 7,
and there is a screw stop (not shown) for the slide f to be screwed back against at
the commencement of each fresh section.
The bracket A³ for the slide f forms the bearing for the screw shaft f¹ which has
a handle f upon it for screwing back the slide f
There is a worm wheel f¹ on the shaft f¹ which can be disengaged or made to
gear with either of two worms each formed on the sides of two discs f 11 on the
section shaft a which are made to slide on a key thereon.
There is a thin elastic lever m jointed to one of the discs f¹¹ at m¹, which lever
has a projection that in one of its positions will enter a hole in the shaft a and will
thus hold one or the other worm discs f¹¹ in gear with the worm wheel / 10 when the

page_text: worm discs are slided endways on the shaft or both worm discs may be out of gear
when required-The end of the elastic lever m has a pin on its side that enters a
hole in the disc f" when the pin or projection is in the hole in the shaft a but the
lever being elastic it can be withdrawn from the hole in the disc f" when the
worm discs have to be moved.
The screw shaft f¹ may be driven in any other convenient manner from the
section shaft a.
Figs 22 to 27 illustrate how the horizontal and diagonal slides are combined
with a lever fast on the presser shaft b, (or fast when warping sections not being
standard sections) for that system of warping in sections, where the warp threads
as they wind on the section are confined to and are compelled to wind on in a
given space the presser being moved by the machine to give the space as the section
is being wound. A is a slideway formed on or secured to the side of the framing A,
f¹ is the screw shaft for actuating the slide f being rotated from the section shaft
by mechanism hereinbefore or hereinafter described or any other convenient
arrangement of mechanism, there being a handle as in fig 19 for screwing back the
screw to bring the slide into the position against a screw adjustable stop (not
shown) for starting the warping of the section.
The slide in this arrangement moves the reverse way to that described in
reference to figs 1 to 7-The slide f is horizontal or at a tangent to a line radial
from the presser shaft b midway between the centre line positions of the arm o on
the presser shaft in its position when the section is empty and when filled to the
full extent.
The centre line of the diagonal or oblique arm or slideway g coincides with the
centre line of the lever c when in its position when the section block is empty.
There is a slide g³ on the diagonal slideway g adjusted up and down by a
screw gl and this slide g³ has a pivot for a block g³ to swivel upon which grasps
each side of the lever c¹ which iù this modification is loose on the presser shaft b
There is a second lever c fast on the section shaft b and these levers are made to
move together after the standard section has been made by a pin c² that passes
through a hole in both levers, when they are brought exactly opposite each
other.
The screw f¹ in this and other modifications hereinbefore and hereinafter
described is of the pitch or is geared up with the section shaft to give about the
amount of motion in the slide f for a section of average counts,.when the slide g³
on the diagonal arın g is in about the middle of it in which case other required
variations from medium counts can be obtained by screwing the slide g³ up and
down the arm g.
When making the standard section the pin c² is removed to leave the loose arm c¹
at liberty, then the slide f being screwed back to the position for starting the section
the standard section is made and.when finished before it is removed the screw g¹ is
turned to screw the slide g³ up or down as required until the loose arm c¹ exactly
coincides with the fast arm.c when the pin c can be clearly inserted through the
holes in both and the machine is then ready for warping sections in agreement
with the standard section. It will be understood, that when making the standard
section the presser is pressed against the section by a weight on the arm secured.
on the section shaft b in the usual manner.
In figs 24 and 25-the slide fand diagonal arm g is formed by a cross piece,
which slides in bearings formed on the framing; A7 are caps each secured by a
screw passing through a slot in the slide f. There is a screw f¹ to move the slide
to and fro.
The diagonal or oblique arm g has a dove tailed slideway for a slide.g³ and there
is a set screw 96 that screws into this slide and against the face of the diagonal
slideway g when it is to be secured thereto.
This set screw go forms the axis for a swivel block go that grasps the sides so as
to slide on the arm c fast on the presser shaft b. The set screw g is taken out

page_text: when the standard section is being made and when finished both the slide g³ on
the diagonal arm g and that go grasping the arm c are moved up or down until the
set screw. g can be clearly inserted through both and secured against the diagonal
slideway g this junction of the two slides is at the intersection of the centre lines
of the arm c with the centre line of the diagonal slideway 9.
Figs 24 and 26 show. how the screw f¹is or may be rotated from the section
shaft a by two alternately acting ratchet pawls acting upon a broad ratchet
Wheel 10 fast on the screw shaft f
There is a drum cam n fast on the section shaft a which acts on a bowl on a
lever n having its fulcrum on a stud n? in a bracket A secured to the framing-
There are two of this levers n' on the same fulcrum stud n2 but as they are on
opposite sides of the cam n they act alternately one lever moving back as the
other moves forward and this imparts continual motion to the ratchet f10 except a
slight pause caused by the play between the ratchet pawls and the teeth of the ratchet.
Fig 27 shows a. section through the diagonal slideway g slide g³ the swivel
slide block g³ and the lever c which is slotted in its lengthway to allow the screw go
to pass through.

invention and in what manner the same is to be performed, I declare that what
