page_text: I, WILLIAM CLIFFE, of the Firm of Cliffe and Company, of Perseverance Iron
Works, Longwood, near Huddersfield, in the County of York, Machine Makers, do
hereby declare the nature of this invention to be as follows:-
This invention relates to sectional warping machines and comprises means for
accurately and automatically determining the position of the carriage or section
builder before commencing to wind each new section of warp on to the swift.
For the purpose of my invention I employ a long screw shaft placed parallel
with the ordinary screw shaft which actuates the carriage or sector builder and
driven therefrom by suitable gearing. This additional screw shaft works into a
toothed wheel mounted loosely on a stud secured within a box or enclosing casing
which is adapted to slide laterally on the same bed on which the section builder
slides. The toothed wheel is provided at one side with a plain periphery or
flanged pulley and around said periphery or pulley there passes a brake strap one
end of which is attached to a cross shaft journalled in bearings in the aforesaid
box and the opposite end to a lug projecting from a boss on such shaft. On said
cross shaft and, within the box, is mounted a lever connected to a rod whose free
end passes through one side of the box and is provided at its outer end with an
enlargement or collar. On the outer end of the cross shaft is secured an arm
or lever suitably weighted and adapted to engage a trigger lever or catch pivotted
to the box.
On the ordinary shaft over which the warp is guided to the swift I place loosely
a distance piece which is attached by rod to the adjustable boss, or it may be
mounted on a sleeve or otherwise connected to and moveable with the boss, by
which the width of the section of warp to be wound on to the swift is determined.
When the said boss is adjusted to the width of section required, the distance
piece, by means of the connecting rod, is likewise adjusted on the shaft to the
same extent. Before commencing to wind a section the section building carriage
is brought close to the box in doing which it presses against the projecting end
of the rod located therein and actuates the lever and cross shaft in such manner
as to raise the arm on the outer end thereof, which is thereupon engaged by the
trigger or pivotted catch and locked in its elevated position, the movement of
the cross shaft simultaneously tightening the brake strap sufficiently to prevent
the toothed wheel from rotating under the action of the screw shaft whereby the
box and parts are traversed laterally away from the section builder by said screw
shaft a distance equal to the width of the section of warp being wound on the
swift when it comes up to the distance piece which engages with the
trigger and moves it out of engagement with the locking arm, the
result being that the brake strap is slackened allowing the toothed wheel to
rotate idly under the continued motion of the screw so that the box remains
stationary while the actuating lever and rod move back to their former positions
in readiness for the commencement of the next section. After each section is

page_text: completed the carriage and section builder are slided up to the box whose position
in every case accurately determines the position of the gauge and section builder
for winding on the succeeding section, the engagement of the carriage with the
projecting end of the rod when brought up to the box against placing the arm in
engagement with the trigger and tightening the brake strap so that the box and
parts may be moved to the next position for determining the position of the
section builder to wind on a subsequent section this being repeated for every
section which is to be wound on the swift.
The additional screw shaft is of coarser pitch than the ordinary screw so that the
box and parts arrive at their destination early in the winding of the section on the
swift.
In order to enable the box to be slided freely back to the opposite end of the
swift after the required number of sections have been wound thereon I employ a
plate which is normally held tightly against the bed on which the box slides by
means of a flat spring and stud or finger maintained under pressure by an eccen-
tric or cam mounted on a short shaft journalled in bearings at the rear of the
box. On said shaft is a hand lever which the attendant operates when desiring to
release the box, the partial rotation of the short shaft bringing the smaller radii of
the cam opposite the stud or finger which relieves the spring and removes the
pressure off the plate thereby enabling the box to be freely slided back to the
starting point. The lever is locked in both positions by engagement with suit-
able recesses or projections.
By the means aforesaid, the adjustment of the gauge to any width of section,
automatically determines the exact position to which the section builder must be
moved before commencing to wind on each succeeding section and is entirely
independent of the attention of the person in charge.

I, WILLIAM CLIFFE, of the Firm of Cliffe and Company, of Perseverance Iron
Works, Longwood, near Huddersfield, in the County of York, Machine Makers, 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 and comprises means for
accurately and automatically determining the position of the carriage or section
builder before commencing to wind each fresh section of warp on the cylinder or
swift.
For the purpose of my invention I employ a long screw shaft placed parallel
with the ordinary screw shaft which actuates the carriage or section builder and
driven therefrom by suitable gearing. This supplementary screw shaft works
into a toothed wheel mounted on a stud secured within a box or casing which is
adapted to slide laterally on the same bed on which the section Huilder slides.
The toothed wheel is provided at one side with a plain periphery or flanged pulley
and around said pulley there passes a brake strap, one end of which is attached
to a cross shaft journalled in bearings in the aforesaid box, and the opposite end
to a lug projecting from a boss on said shaft. On the cross shaft, and also within

page_text: the box, is mounted a lever connected to a rod whose free end passes through one
side of the box and is or may be provided at its outer end with an enlargement
or collar. Secured on the outer end of the cross shaft is an arm or lever suitably
weighted and adapted to be engaged by a trigger lever or catch pivotted to the box.
On the ordinary shaft over which the warp is guided to the cylinder I place
loosely a distance piece which is attached by rod to the adjustable boss, or it may
be mounted on a sleeve or otherwise connected to and moveable with the said
adjustable boss which is set to the width of the section of warp.
When the adjustable boss is moved to the width of section required the distance
piece, by means of the connecting rod, is likewise adjusted on the shaft to the
same extent. Before commencing to wind on a section of warp, the section
building carriage is brought close to the box in doing which it presses against the
projecting end of the rod located therein and actuates the lever and cross shaft in
such manner as to raise the weighted arm until it is engaged and locked by the
trigger lever or catch, the movement of the cross shaft simultaneously tightening
the brake strap sufficiently to prevent the toothed wheel from rotating under the
action of the screw whereby the box and parts are traversed laterally away from
the section builder by said screw a distance equal to the width of the section of .
warp being wound on the cylinder, when it comes up to the distance piece on
the section builder which engages the trigger and moves it out of engagement
with the weighted locking arm, the result being that the brake strap is slackened,
allowing the toothed wheel to rotate idly under the continued motion of the screw
so that the box remains stationary at the point to which it has been moved. After
each section of warp is completed, the carriage or section builder is slided up to
the box, whose position in every case accurately determines the position of the
gauge and section, builder for winding on the succeeding section, the engagement
of the carriage with the projecting end of the rod again placing the weighted
arm in engagement with the trigger and tightening the brake strap so that the box
and parts may be moved to the next position for determining the position of the
section builder to wind on a subsequent section, this being repeated for every
section which is to be wound on the cylinder of the machine.
The supplemental screw is of coarser pitch than the ordinary screw or is driven
at a higher speed, so that the box and parts arrive at their destination early on in
the winding of a section of warp.
On
To enable the box to be slided freely back to the end of the machine after the
full or required number of sections have been wound thereon, I employ a plate
which is normally held tightly against the bed, on which the box slides by means
of a flat spring and stud or finger maintained under pressure by an eccentric or
cam mounted on a short shaft supported in bearings at the rear of the box.
said shaft is a hand lever which the attendant operates when desiring to release
the box, the partial rotation of the short shaft bringing the shorter radii of the
cam opposite the stud or finger which relieves the spring and removes the pressure
off the plate, thereby enabling the box to be freely slided back to the starting
point.
In order that my said invention may be fully understood, reference is hereafter
had to the annexed sheet of drawings forming a part of this Specification in
which: :—
Fig. 1 is front sectional elevation, taken on line A, B, of Fig. 3, of my improved
mechanism for automatically determining the position to which the carriage or
section builder must be moved for winding each section of warp side by side on
the cylinder or swift of the machine, the parts being in the positions assumed
when commencing to wind on a section of warp;
Fig. 2 is a similar sectional elevation to Fig. 1 shewing the parts in the posi-
tions taken up during the winding on of a section of warp to determine the
position to which the section builder must be moved for winding the next succeed-
ing section of warp on the cylinder or swift;
Fig. 3 is a transverse section taken on line C, D, of Fig. 1; and

page_text: Fig. 4 is plan view of Fig. 3, the lid of the box being omitted.
Referring to the drawings letter a represents the table or bed, at the front of
the warping machine, on which the section builder rests and is adapted to slide
laterally across the front of the cylinder or swift (not shewn); the section builder
or carriage of same, from which the parts not essential to my invention are
omitted; and c (Figs. 3 and 4) the screw for traversing the section builder end
wise on the table a in the direction of arrow E (Fig. 1) in winding each section
of warp on the cylinder to build up the same to the required angle.
The section is provided as ordinarily, with the shaft or rod d over which the
warp is guided to the cylinder, and with the adjustable boss or gauge piece e and
fixed boss f by which the width of the section of warp is determined or set off
on the section builder.
The aforesaid parts are precisely as heretofore the rod or shaft d, however, being
of such a length as will allow it to project a suitable distance beyond the left
hand end of the section builder to carry thereon a second adjustable boss or
distance piece y and admit of the maximum adjustment thereof to serve for the
widest section of warp which is brought to the machine.
The said boss or distance piece g is attached by a rod h to the ordinary adjust-
able boss e; or, it may be mounted on a sleeve, or otherwise connected to and
moveable with the boss e, this rigid connection of one adjustable boss to the
other ensuring that when the boss e is adjusted to measure off a space on rod d
between it and the fixed boss f corresponding to any width of section of warp,
the boss g will also in like manner and to the same extent, be adjusted on the
outer end of rod d. As a factor of safety, I may secure on the outer end of rod da
collar which corresponds to the fixed boss f and enables the attendant at any
time, by measurement between and i to satisfy any doubt there may arise as to
inequality of adjustment of the bosses eg which may result from or caused by
some independent or accidental movement in the connection. The boss or
distance piece g is secured, after adjustment, by a thumb screw g
Mounted at each end in bearings in the table or bed a and located in the trough
or well of said bed, is a supplementary or additional screw k parallel with the
screw c and driven therefrom by a spur wheel c¹ (Fig. 3) gearing into a pinion k¹
on the screw k.
This supplementary screw k works into a toothed wheel mounted loosely on a
stud secured within a box or enclosing casing m which rests on and is adapted
to be slided laterally on the bed or table a. The said wheel is provided on its
near side with a plain periphery or flanged pulley and around such pulley is
passed a brake or friction strap n, one end of which is attached to a cross shaft o
journalled in bearings in the aforesaid box m, whilst the opposite end is secured
to a lug or finger p projecting from a boss pl fast on the cross shaft o. On said
cross shaft and also within the box m, is mounted a lever to the upper end of
which is attached a rod whose free end passes through the right hand side of
the box m. On the outer end of the cross shaft o, that is at the rear of the box m.
is secured an arm or lever s suitable weighted at its extremity and provided
with a projecting lug s¹ with which is adapted to engage a shoulder t' on a trigger
lever or catch t pivotted at t² to the box m.
The supplementary adjustable boss or distance piece on rod or shaft d is pro-
vided with a depending arm or finger g² which when the lever or arms is engaged
or locked by the trigger lever or catch t, as shewn at Fig. 1, lies in the path of the
extremity of the trigger lever and at the proper time, as afterwards explained, is
adapted to abut against said lever and force it upon its centre out of engagement
with the weighted lever arms, as shewn at Fig. 2.
For the purpose of bringing the section builder into position for winding a
section of warp on the cylinder the attendant slides the section builder & laterally
up against the box or casing m (the parts of which prior to this taking place are
in the positions shewn at Fig. 2,) and in so doing an engagement piece b¹ on said
carriage strikes the projecting end of the red and forces it inward to its full

page_text: extent thereby moving the lever q over to the position shewn at Fig. 1, and par-
tially rotating the cross shaft o which elevates the weighted lever or locking arm s
sufficiently to allow the shoulder t on the trigger lever or catch t (which is
weighted at 3 to maintain it always in contact with said lever arm s) to pass under
and engage with the lug s¹ on the weighted lever arm which is thus locked in its
elevated position and rigidly holds the cross shaft o until again released. The
movement of the cross shaft o as above, is for the purpose of raising the lug or
finger p, on fixed boss pl so as to tighten the brake or friction strap n around
the flanged pulley 2 and prevent further rotation of the toothed wheel 7. On the
toothed wheel thus being locked or held rotatively, it acts as a nut and is con-
strained by the continued notion of the screw to travel laterally in the direction
of arrow (Fig. 1) taking with it the box m and parts connected therewith.
By the time the said box or casing has travelled along the bed a distance
equal to the width of the section of warp, as determined by the position of the
adjustable bosses e, g, the finger g² on boss g, travelling with the section builder
to the right, or in the direction of arrow E, (Fig. 1,) arrives at and strikes against
the trigger levert and moves it out of engagement with the weighted lever arm s,
whereupon the cross shaft o by reason of the weighted lever arm s, is turned
back again or released and places the parts in the positions shewn at Fig. 2,
thereby slackening the brake strap n and allowing the toothed wheel 7 to rotate
idly to take up the motion of the screw k. The lateral movement of box m is
thus stopped and it remains stationary in a position in advance of that last occupied
exactly equal to the width of the section of warp, as shewn at Fig. 2, thus auto-
matically determining the position to which the section builder must be moved to
wind on the succeeding section.
The driving of the screw k at a higher speed than the ordinary screw c causes
the box m and parts to travel the requisite distance early on in the winding on of
the section of warp, though the attainment of position may take place any time
during the winding of a section of warp, as preferred. The same result may be
obtained by making the screw of coarser pitch or by driving a screw of coarser
pitch at a slightly higher speed than the ordinary screw c.
When the section of warp being wound on the cylinder, is completed, the
attendant as ordinarily, slides back the section builder in the direction of
arrow F (Fig. 1) but, by reason of my improved mechanism, its exact position
for winding on the next succeeding section of warp is determined by the position
taken up by the box or casing m during the winding of the aforesaid section and,
therefore nothing more is required than to force the section builder up against
the said box m which ensures in every case the accurate delivery of the succeed-
ing section of warp alongside the last section wound on the cylinder. As before
described the engagement of the carriage or section builder b with the box m
actuates the rod and lever q and re-establishes the parts in their locked positions,
as in Fig. 1 so that said box and parts immediately commence to advance in the
direction of arrow F (Fig. 1) to the next position for determining the position of
the section builder to wind on a subsequent section of warp, the same cycle of
actions being repeated at the commencement of each section of warp and when the
box and parts have travelled forward to the left a distance equal to the width of
the section of warp.
The adjustment of boss e to a wider or narrower section of warp determines,
through the corresponding adjustment of boss g the increased or reduced extent of
traverse of the box m for each section of warp to be wound on the cylinder.
In order to enable the box m to be slided freely back from the rear to the front
end of the cylinder after the full number of sections have been wound thereon I
employ a plate u which is normally held tightly against the planed rear edge of
the bed a by means of a bow or flat spring having a shank or stud against the
outer end of which acts an eccentric or cam 10, mounted on a short shaft w¹ jour-
nalled in bearings at the rear of the box m, and maintains said spring under
pressure. On the said shaft w¹ is secured a lever provided on one side with a

page_text: web which normally is engaged in a recess in a rib m¹ on the side of the box m
as shewn.
The face of said rib m' is slightly inclined or wedge shaped so that a
little pressure is required to release the lever, or to engage it in the recess.
When the attendant desires to release the box m, the lever is forced upward
thus partially rotating the short shaft w¹ and bringing the shorter radii of cam w
opposite the shank or finger el which relieves the spring and removes the pres-
sure off plate u, thereby enabling the box to be freely slided back to the starting
point.
By the means herinbefore described the adjustment of the ordinary gauge to
any width of section of warp, automatically determines the exact position to
which the section builder must be moved to wind each succeeding section of warp
on the cylinder and is entirely independent of the attention of the person in
charge.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim
is;
(1.) In sectional warping machines, the improved mechanism, for automatically
determining the position of the section builder for each successive section of warp,
comprising a box or casing adapted to be moved laterally to predetermined
extents, on the table or bed supporting the section builder, by means of a separate
screw gearing with a toothed wheel in said box, a brake or friction strap passing
around a brake or flanged pulley on said toothed wheel and attached at one end
to a cross shaft carried by the box and at the opposite end to a stud or finger
projecting from an armed boss fast on said cross shaft, a lever secured on the
cross shaft and adapted to be actuated by the abutment of the carriage or section
builder with the end of a rod connected to said lever, means for locking said cross
shaft in position when turned to tighten the brake strap around the brake pulley,
and an additional or supplementary gauge or distance piece mounted loosely on the
rod d of the section builder and connected by rod to the ordinary adjustable boss
or gauge for setting of the width of the section of warp so as to be moveable or
adjustable therewith, all arranged and acting in the manner and for the purposes
substantially as herein shewn and described.
(2.) In sectional warping machines the combination, with the herein described
means for automatically determining the exact position to which the section
builder must be moved to wind on each succeeding section of warp, of a plate
such as u engaging the planed rear edge of the bed a, spring acting on said
plate, cam such as we working against a stud or shank on the spring, and a lever
for actuating said cam and means for locking the lever, substantially as herein
shewn and described.
(3.) In sectional warping machines the general arrangement combination and
operation of the several parts comprising the improved mechanism herein described
and shewn for automatically determining the position of the section builder for
winding on each section of warp side by side on the cylinder or swift substantially
as set forth.
