Improvements in or Appertaining to Sectional Warping Machines.
We, WILLIAM CLIFFE and MAJOR CLIFFE, both of Longroyd Bridge Iron
Works, Huddersfield, in the County of York, Engineers and Machine Makers,
and OSWALD MOORHOUSE, of the same place, Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to sectional warping machines in which the section of
warp to be wound on the cylinder or swift is delivered thereto over or between
a guide on the section builder, which latter is traversed laterally on a slide or
table in one direction by a driven longitudinal screw to build up the warp
to the required section, and slided back in the opposite direction by hand, to
bring the section builder into position for winding on the succeeding section,
and our improvements comprise the application to said section builders of means
whereby the position of same to commence winding on a fresh section of warp
may be accurately and automatically determined without any further attention
on the part of the attendant after once making the necessary adjustment to
the width of warp being dealt with, no further adjustment or alteration being
necessary until a wider or narrower section of warp is to be wound on the machine.
In carrying out our invention we employ a moveable rod or shaft of suitable
length which extends at each end through the end or side pieces of the section
builder and is free to be slided endwise in openings or bearings therein one
outer end of said rod carrying a boss, disc or distance piece, which can be
moved laterally on the rod and fixed at any distance from the side of the section
builder, or carriage of same, to suit the width of any section of warp, its position
when adjusted, determining the extent of movement of the section builder when
traversed to the left to bring it accurately to the required position to wind on
another section. Formed on or attached to the underside of said rod or shaft
are a number of teeth, or a rack, into which gears a spur wheel mounted on the
ordinary cross shaft whereon the hand or brake wheel and worm toothed wheel
gearing with the longitudinal screw are secured. Said spur wheel is free to
turn on the cross shaft, and is also adapted to be moved laterally thereon into
or out of engagement with a friction disc, cone, or clutch, fast on the cross shaft
so as to be driven thereby, or disconnected and put out of action. On the stud
or shaft, to which one end of the metal or brake strap encircling the hand or
brake wheel is attached, we secure a cam or other similar device
adapted to act on one end of a lever whose opposite end is forked or otherwise
adapted to engage a collar or annular recess on the boss of the loose spur wheel
and to slide it into or out of an engagement with the friction cone, disc, or
clutch, as and when required. The section builder is traversed laterally to the
right to build up the warp by means of the driven longitudinal screw or worm
engaging with the worm or foothed wheel fast on the cross shaft which, being
held stationary by the brake or metal strap drawn tightly against the periphery
of the brake or hand wheel acts as a nut and is thus moved to the right at the
speed and to the extent required and carries the section builder with it, the
return movement of said section builder to the position for commencing to wind
en the next section being effected by releasing the brake or metal strap and

page_text: rotating the hand wheel, which revolves the cross shaft and worm or toothed
wheel fast thereon, the latter thus acting as a pinion and the worm or screw
forming a rack along which the pinion travels and slides the section builder
with it; the above method of and means for traversing the section builder to
right and left being as ordinarily and not affected by our improvements.
In order to accurately and automatically determine the extent to which the
section builder must be traversed to the left after the completion of each section
to bring it into position to wind on the next section, the boss, disc, or distance
piece, on the outer end of the toothed rod or shaft is moved on said rod in one
direction or the other until the distance between it and the side of the section
builder or other fixed part of same corresponds to the width of the warp to be
dealt with, or bears a definite relation thereto, in which position it is then
secured by screw or like means. This may be done by measurement before
winding on the first section of warp, or set off from the first section of warp
when completed. The release of the brake or metal strap on the completion
of each section of warp to allow of the section builder being slided to the left,
causes the cam previously mentioned to act on the fork lever so as to place the
loose spur wheel into contact with the friction disc, whereby said spur wheel
is rotated and causes the toothed rod or shaft to slide to the left against the
resistance of a confined spiral spring engaging with a fixed part on the rod or
shaft. The endwise motion of the said rod is such that by the time the distance
piece or moveable boss secured thereon abuts against the side of the section
builder which is sliding in the same direction, the latter occupies a position
exactly and accurately presenting the guide of same opposite the part of the
cylinder on which the next section of warp must be wound. The tightening
of the metal strap around the hand wheel or disc to commence winding on the
new section of warp, causes the loose spur wheel to be thrown out of contact
with the friction disc, whereupon the spiral spring above referred to expands
and forces back the toothed rod or shaft to its normal position in readiness for
determining the position of the section builder on its next movement to the
left for winding on another section of warp, this being repeated for every section.

Improvements in or Appertaining to Sectional Warping Machines.
We, WILLIAM CLIFFE and MAJOR CLIFFE, both of Longroyd Bridge Iron
Works, Huddersfield, in the County of York, Engineers and Machine Makers,
and OSWALD MOORHOUSE, of the same place, 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:—
This invention relates to sectional warping machines in which the section of
warp to be wound on the cylinder or swift is delivered thereto over or between
a guide on the section builder, which latter is traversed laterally on a slide or
table in one direction, by a driven longitudinal screw to build up the warp

wider or narrower section of warp has to be wound on the machine.
In carrying out our invention we employ a moveable rod or shaft of suitable
length which extends at each end through the end or side piece of the section
builder and is free to be slided endwise in openings or bearings therein, one
outer end of said .rod carrying a boss, disc, or distance piece, which can be

adapted to act on one end of a lever whose opposite end is forked or otherwise
adapted to engage a collar or annular recess in the boss of the loose spur wheel
and to slide it into or out of engagement with the friction cone disc, or

right to build up the warp by means of the driven longitudinal screw or worm
engaging with the worm or toothed wheel fast on the cross shaft, which, being
held stationary by the brake or metal strap drawn tightly against the periphery
of the brake or hand wheel, acts as a nut and is thus moved to the right at the
speed and to the extent required, and carries the section builder with it, the
return movement of said section builder to the position for commencing to wind
on the next section being effected by releasing the brake or metal strap and
rotating the hand wheel which revolves the cross shaft and worm or toothed
wheel fast thereon, the latter thus acting as a, pinion and the worm or screw
forming a rack along which the pinion travels and slides the section builder
with it; the above method of and means for traversing the section builder to
right and left being as ordinarily and not effected by our improvements.
In order to accurately and automatically determine the extent to which the
section builder must be traversed to the left after the completion of each section
to bring it into position to wind on the next section, the boss, disc, or distance
piece, on the outer end of the toothed rod or shaft is moved on said rod in one
direction or the other until the distance between it and the side of the section
builder or other fixed part of same corresponds to the width of the warp to be
dealt with, or bears a definite relation thereto, in which position it is then
secured by screw or like means. This may be done by measurement before
winding on the first section of warp, or set off from the first section of warp
when completed. The release of the brake or metal strap on the completion
of each section of warp to allow of the section builder being slided to the left,
causes the cam previously mentioned to act on the fork lever so as to place the
loose spur wheel into contact with the friction disc, whereby said spur wheel
is rotated and slides the toothed rod or shaft to the left against the
resistance of a confined spiral spring engaging with a fixed part on the rod or
shaft. The endwise motion of the said rod is such that by the time the distance
piece or moveable boss secured thereon abuts against the side of the section
builder (which is sliding in the same direction) the latter occupies a position
exactly and accurately presenting the guide of same opposite the part of the
cylinder on which the next section of warp must be wound.

page_text: The tightening of the metal strap around the hand wheel or disc to commence
winding on the new section of warp, causes the loose spur wheel to be thrown
out of contact with the friction disc, whereupon the spiral spring above referred
to expands and forces back the toothed rod or shaft to its normal position in
readiness for determining the position of the section builder, on its next move-
ment to the left, for winding on another section of warp, this being repeated
for every section.
In the accompanying drawings forming a part of this specification:-
Fig. 1 is sectional elevation of so much of the section builder of a sectional
warping machine as is essential to shew the application of our improvements;
the hand brake wheel and parts and lever for applying and releasing the brake
strap all located on the front or detached part of the section builder, being shewn
in dotted lines;
Fig. 2 is a plan view of Fig. 1; and
Fig. 3 is sectional detail taken on line 1, 2, of Fig. 1.
Referring to the drawings, our improvements consist in the application to
the section builder, represented at a, of a shaft, bar, or rod b, of suitable length,
extending across and through each side of the section builder and supported
loosely in openings or bearings therein so as to be free to slide laterally in either
direction, the right hand end of such shaft or bar projecting for some distance
beyond the section builder and carrying thereon a moveable boss, disc, or dis-
tance piece e provided with a set screw d for securing it to the shaft or rod b
in any required position and the projecting left hand end of said shaft or bar
having a collar, shoulder, or enlargement, e secured or formed thereon and pre-
ferably faced on the side nearest the section builder with an india rubber or
other soft or yielding ring or washer e¹ which forms a cushion or buffer between
the said collar or enlargement e and the side of the section builder against which
it is normally in abutment as shewn. The shaft or bar b has teeth b¹ cut on
its underside, or a toothed rack secured thereto, into which gears a pinion f
mounted loosely on the ordinary brake wheel shaft g and adapted to be slided
laterally thereon into and out of engagement with a cone or other equivalent
friction disc or clutch h keyed on the shaft g, by means of a lever i centred on
a stud secured to the section builder, the free end of one arm of said lever
entering into and engaging with the sides of an annular groove f¹ cut or formed
in the boss of the pinion f, and the free end of the opposite arm of lever i
extending into or engaging with a cam groove k or cam or inclined surface or
surfaces, formed in or on a collar or boss secured to the ordinary brake lever
shaft whose partial rotation in one direction or the other through the medium
of camoscillates the lever i to right or left and causes it to move the pinion f
into or out of engagement with the friction disc h. The pinion f is recessed or
hollowed out concentrically opposite the cone friction disc h to receive and fit
the periphery of same.
Alongside the shaft or rod b, and secured at one end to the section builder a,
is a spindle m surrounded by a spiral spring n which is confined between a
collar or shoulder m¹ secured to or formed on the left hand end of said spindle
and a finger or projection 62 secured to the rod or shaft b and adapted to slide
on the spindle m.
To the shaft g, are secured the usual hand or brake wheel or pulley o, and
toothed or worm wheel gearing with the longitudinal driven screw or worm g
by and through the medium of which the section builder is traversed to right
or left, and secured on the shaft are the usual lever r, to whose opposite
extremities the two ends of the brake strap o', encircling the brake pulley o,
are attached, and the lever s for applying and releasing the brake.
The section builder is traversed to the right, to build up the warp to the
required section, by the revolving screw working in the teeth of the wheel p
which is restrained from rotating by the steel brake strap on the pulley o
and therefore acts as a nut whereby the section builder is propelled' bodily for-

page_text: ward along the table or slide t, the said brake strap, being tightened around the
pulley o by lowering the levers from the position shewn in Fig. 1 to its lowest
position (not shewn). On the completion of the winding on of a section of
warp, the lever s is raised and locked by catch or locking lever s', in the position
shewn in Fig. 1, thereby slackening the brake strap and allowing the brake
wheel o to be revolved by hand, the attendant turning said wheel in the direction
of arrow u and rotating the worm or toothed wheel p which now travels over the
teeth of the screw or worm q and propels the section builder bodily with it
along the table or slide t to the left to bring it into position for winding on
another section of warp, the lateral traverse of the section builder to right and
left as briefly described being effected in the ordinary well known manner and
forming no part of our invention.
When the brake lever s is raised to release the brake strap o¹ for the purpose
of permitting the section builder to be traversed to the left, as last described,
it turns the shaft 7 partially around in its bearings in the direction of the upward
movement of said lever, thus giving part of a turn to the cam k which actuates
lever and moves the pinion f laterally on its shaft into contact with the fric-
tion cone or disc h, the latter, on shaft g being rotated by the hand wheel o,
driving said pinion, whose rotation propels the shaft or bar b to the left, or in
the same direction as the section builder itself is being traversed, the spring n
being compressed by the endwise movement of the shaft or bar b to the left
hand and serving to re-instate the parts in their normal positions immediately
the lever s is lowered to tighten the brake strap o around the wheel o to com-
mence winding on a fresh section of warp.
In order to accurately determine the exact distance which the section builder
must be traversed to the left to bring the guide or gauge v thereof into proper
alignment with the part of the cylinder on which each, succeeding section must
be wound to build it up contiguous to the preceding wound on section of warp,
the boss, disc, or distance piece e is adjusted to or from the near side of the
section builder to such a distance as may be calculated by measurement to
bear the proper relative proportion to the width of the section of warp to be
dealt with, that is the exact width of such section plus the distance traversed
by the section builder in building up the section. Preferably, to ensure per-
fect accuracy, the disc, or distance piece c is adjusted to the precise position on
shaft after the first section has been wound on the cylinder and the section
builder slided back to the left and adjusted by the attendant to guide the next
section of warp on the machine, the said disc e then being slided up against
the section builder and secured by set screw d, this position, when once obtained,
ensuring the accurate positioning of the section builder for winding on every
subsequent section so long as the width thereof remains the same and therefore
avoiding all further adjustment until a section of warp of a different width
has to be dealt with. Having thus adjusted and secured the disc e, the lever s
is released to tighten the brake strap o¹ and set the section builder travelling
to the right while winding on the warp the descent of said lever turning the
shaft partly round and through cam k, actuating the lever i which slides the
pinion out of engagement with the friction disc h whereupon being free to
rotate on its shaft, the compressed spring n immediately expands and acting
against the finger 62 forces the shaft or rod bendwise in its bearings until the
stop e on its left hand end abuts against the section builder and stops further
movement, the washer or ring e' cushioning the impact. The distance now inter-
vening between the side of the section builder and the disc c as shewn in full
line in the drawings, thus forms the gauge for determining the exact distance
the section builder must be traversed to the left to bring it into position for
winding on each successive section of warp, the parts comprising our said
improvements remaining in their normal position as shewn, until the winding
on of the section is completed. On this taking place the brake lever is raised
and locked in the position shewn at Fig. 1, this movement of said lever turning

page_text: the shaft as before described and through worm k, actuating lever i which
places the pinion f into engagement with the friction disc so that when the
shaft is rotated by hand wheel o to traverse the section builder to the left,
the friction disc revolves the pinion f, which propels the shaft or rod b also
to the left, the combined movements continuing until the disc or distance
piece abuts against the side of the section builder and prevents any further
motion of pinion f and shaft g, the stoppage thus being automatically or self-
actingly brought about and the guide presented precisely in the position for
guiding the next section of warp on to the cylinder contiguously to the last
wound on section without attention or necessity for adjustment of the section
builder. The application of the brake to build up the section of warp on the
cylinder throws the pinion out of gear with the friction driving cone hand
allows the shaft or rod b to be immediately forced back to its normal position
by the spring in readiness for the next return movement of the section
builder, the same cycle of operations being repeated at the conclusion of the
winding on of each section of warp and the return movement to the left of the
section builder.
The details of construction or arrangement of the parts comprising our
improvements may be varied somewhat if desired, as for instance, the spindle
and spring n thereon could be dispensed with, a coiled spring attached at one
end to the shaft or rod band at the opposite end to the section builder so as to
be drawn out or expanded by the movement to the left of the said rod b, being
employed instead thereof; and in lieu of the lever i being moved in both direc-
tions by a cam as described, it may be moved in one direction by a cam to place
the pinion into engagement with the friction cone and in the opposite direc-
tion by a spring.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) In a sectional warping machine, the combination, with a section builder
such as a, of a toothed shaft rod or bar, such as provided with an adjustable
disc, boss, or distance piece, adapted to be secured thereon at any required
distance from the side of the section builder, or a fixed part thereof, propor-
tioned relatively to the width of the section of warp and the extent of movement
of the section builder in building up the warp on the machine, means for
traversing the said shaft or bar positively to the left simultaneously with the
traverse of the section builder in the same direction to bring the disc or distance
piece into abutment with the section builder and stop further progressive
movement immediately said section builder arrives in the exact position for
guiding on the next section of warp, and means for reinstating the parts in
their normal positions on commencing to wind on each section of warp sub-
stantially as herein set forth and shewn on the drawings annexed.
(2) In a section builder for sectional warping machines the combination of
the toothed shaft or rod b provided with an adjustable boss, disc, or distance
piece, cand a stop piece e, pinion f, friction driving disc or clutch h, lever i,
cam k, and spring n, all arranged and operating in the manner and for the
purposes substantially as herein shewn and described.
