PROVISIONAL SPECIFICATION.
Improvements in and connected with Sectional Warping Machines.
I, WILLIAM ARTHUR BOOTH, of Bridgewater Mill, Walkden, near Bolton, in
the County of Lancaster, Manufacturer, do hereby declare the nature of this
invention to be as follows :-
or
My invention relates to the kind of warping machines known as sectional warping
machines and consists in improved arrangements for operating the "pressers
press bowls of said machines and for winding a number of sections successively
upon sectional warp beams, and in the construction of said warp beams.
The sectional warping machines hitherto used wind a section of the warp upon a
section block, these blocks being subsequently mounted in the required number
upon a shaft and the warp thus combined drawn off the blocks and rewound upon
a warp beam which is transferred to the loom or other machine. The object of
my invention is to obviate this re-winding and also to do away with the numerous
links and levers ordinarily used for holding the presser or press bowl against the
warp, which cause a great amount of back lash and springing and produce irregular
sections.
In carrying out my invention I use warp beams consisting of a centre or shaft
having one end flange fixed upon the same. Upon the shaft I place section blocks
separated from each other by thin discs and against the last block another end
flange so arranged that it can be drawn up against the section blocks and discs to
tighten them and then be fixed upon the shaft. The blocks may be provided with
pins passing through the division plates into the adjacent blocks so as to connect
the whole more securely. The warp beam so formed is placed into bearings on the
machine in line with the machine shaft and driven by a clutch or driver and the
sections are successively wound in the manner hereinbefore described, and when
the whole beam is filled, it can be taken out bodily and transferred to the loom or
other machine without having to be re-wound. Instead of placing and winding the
section blocks upon a separate centre, they may be placed upon the machine shaft
itself, the shaft being carried at its outer end by an easily removeable bearing, and
when filled the section blocks and dividing discs be transferred to another centre or
shaft, which is used on the loom or other machine.
For the purpose of winding the sections successively I arrange parallel to the
warp beam or machine shaft a rail or its equivalent upon which a carriage can slide
and be moved by means of a screw-spindle carried in bearings on the rail and a nut
fixed to the carriage. This carriage is provided with guides or their equivalent in
which a bar fitted with a pressing roller at its end in the usual manner can slide
at right angles to the rail and warp beam or shaft. By means of the screw-spindle
the carriage and presser can be brought opposite to any section so that the pressing
roller passes between the dividing discs or flanges, and when a section has been
filled, moved to the next and so on. The reed for guiding the warp threads is fixed
to the carriage. The presser is drawn back gradually as the section blocks become
filled by the following arrangement. The sliding presser bar has a screw spindle
mounted upon or connected to its outer end in such a manner that the spindle can
be locked and prevented from rotating, or unlocked and rotated. The spindle
passes through a nut formed on or attached to the boss of a worm wheel, which
revolves in a carriage sliding on rails or bars parallel to the warp beam and rail
for the presser carriage. The worm wheel gears with a long worm placed parallel
with said guide bars or rails. The spindle being locked to the presser bar, the

page_text: rotation of the worm will turn the worm wheel and screw the presser bar back-
wards till the section has been filled, when the presser carriage is shifted
opposite to the next and the spindle carries the worm wheel carriage along with
it. The spindle is then unlocked and by turning it by means of a handle the
presser is advanced between the division discs to the section block, when the spindle
is locked again to the presser bar and on the winding being started, the presser is
gradually drawn back as before. Instead of a long worm, a worm sliding on a
shaft with a sliding key and held between brackets or lugs on the wormwheel
carriage may be used. The worm or shaft is by preference rotated by means of a
friction disc keyed upon its end against the face of which a friction pulley adjustable
on a side shaft is pressed, the side shaft being rotated by means of bevil wheels from
the machine shaft. By shifting the friction pulley nearer to or farther from the
centre of the disc, the speed of the worm and presser can be varied, and by shifting
it from one side to the other side of the centre of the disc, the rotation can be
reversed, and if desired the presser moved inwards by this means instead of by
hand as hereinbefore described. Instead of this frictional arrangement, the worm
may also be rotated by means of a ratchet actuated by a pawl and excentric on the
machine shaft, and a train of change wheels.
The arrangement for drawing the presser outwards hereinbefore described is also
applicable to sectional warping machines arranged for winding only one section, or
without the use of the composite warp beam.
For winding a "trial section," I arrange a detachable bell crank lever on a
suitable fulcrum carrying a presser at one end and weighted at the other and fill
the section. The number of revolutions made while doing this is recorded by a
counter and according to the indicated number the friction pulley is set to an index
on the friction disc, or where ratchets and chain wheels are used, the latter are
selected from a table, so that the presser is drawn outwards from the bare section
block to the edge of the dividing discs or flanges by means of the worm, worm wheel
and screw in the same number of revolutions. The bellcrank lever is removed
before the machine is started.
The sectional warp beams herein before described are also applicable in connection
with machines winding a single section only. Each section block after being wound
is transferred to a centre having a flange fixed on it, until the warp is completed,
when the other end flange is fixed upon the centre and the beam ready for use
without being rewound.

COMPLETE SPECIFICATION.
Improvements in and connected with Sectional Warping Machines.
I, WILLIAM ARTHUR BOOTH, of Bridgewater Mill, Walkden, near Bolton, in
the County of Lancaster, Manufacturer, 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 invention relates to the kind of warping machines known as sectional warping
machines and consists in improved arrangements for operating the pressers or press-
bowls of said machines, the object of my invention being to do away with the
numerous links and levers ordinarily used for holding the presser or pressbowl against
the warp, which cause a great amount of backlash and springing, and produce irregular
sections, and also to obtain a uniform rectilinear withdrawal of the presser or
pressbowl for each revolution of the warping block and consequent uniform pressure,
which is not produced by the curvilinear motion of the presser or pressbowl

page_text: resulting from the combinations of links and levers ordinarily used. On the
drawings appended hereunto
Fig. 1 shows a sectional elevation.
Fig. 2 a side view.
Fig. 3 a plan partly in section, projected perpendicularly to line A. B on
Fig. 1, of a sectional warping machine with my improvements, only such parts of
the machine being shewn as are requisite for the explanation of my invention.
On the drawings, a is the warping shaft carried in suitable bearings, and fitted
with a fast flange or disc a' and a moveable flange a' adjustable by means of a nut a³
on the screwed end of the shaft a between which flanges the section block the
warp is wound upon is locked, these parts being arranged in any ordinarily used
manner.
The shaft is rotated in any usual way, for instance by means of a friction
pulley a driven from the machine driving shaft rotating the disc a¹. Parallel to
the shaft a I arrange a crossrail b or its equivalent fixed to the frames 61 b', upon
which crossrail a carriage c is adjustable and can be fixed in its position by means
of the plate below the rail 6 and the screws which are screwed into the carriage
and when tightened grip the rail between the carriage c and plate c¹ and thereby
lock the carriage in its position. The carriage c is bored out for a circular nut d
which is fitted so that it can revolve in the carriage and is held in its position by
the collar d' and a wormwheel e fixed upon the nut d. The nut is tapped for a
screw spindle carrying at the front a presser f' with pressbowl 2, and at the
back a handwheel for its equivalent.
The presser may be arranged in any ordinary way but is preferably constructed,
as shewn on the drawings and described in the Specification of my Patent
No. 10762 of 1890. The presser f' is loose upon the screwspindle so that the
latter can turn in it when a pin is withdrawn and be fixed to the presser by
pushing the said pin through holes in the presser and the screwspindle. The presser
is prevented from turning by means of a rod or bar fixed to it, which passes
through a hole in a lug e on the carriage c. The carriage c is set on the rail b so
that the spindle is in the centre between the flanges a¹ and a², which may be done by
hand or by means of a screw held by means of collars in a boss of the frame and
threaded through a nut attached to the plate c', or by equivalent means. The
wormwheel e gears with a long worm e' cut on the shaft e, or a worm sliding on the
shaft on a key and held between lugs on the carriage c may be used.
While a
section is being wound, the presser is fixed to the spindle by means of the
pin f, so that the spindle cannot rotate, and the shaft e is rotated from the
shaft a in the manner hereinafter described whereby the nut d is rotated through
the worm e and wormwheel e', and the spindle fand presser f' screwed or drawn
back for a uniform distance for each revolution of the shaft a corresponding to
the thickness of the yarn wound on, and a uniform pressure is thus retained until
the section or cheese of warp is finished. With the arrangements of links and levers
hitherto used for withdrawing the presser the latter moves in a curvilinear path
and at a varying rate for each revolution of the shaft, the movements being
generally the slower the farther the presser recedes from the centre of the winding
shaft a, so that if the movement corresponds with the thickness of the yarn at the
outer circumference of the cheese, the inner part is wound slackly, or if the inner
part is wound properly, the outer part is unduly compressed and the yarn crushed
and the size rubbed out. These disadvantages are completely obviated by the
improved arrangement of presser operating mechanism hereinbefore described.
When a section has been finished and removed from the shaft a, the presser f¹ is
brought forward again by turning the spindle by means of the handwheel f³ after
the pin has been withdrawn, the nut d being held stationary by the wormwheel e
while the machine is stopped for the removal of the finished section. After the
presser has been pushed up to the bare section block, the pin f* is pushed in again
and the machine restarted, when the presser will be drawn back in the manner
herein before described.

page_text: The details of the mechanism and parts may be varied and replaced by their
mechanical equivalents.
For instance, the nut d may be rotated by a ratchet fixed on the same and a
pawl actuated by an excentric or cam on shaft e² instead of the worm and wormwheel;
the screwspindle may be replaced by a helical rack sliding in the carriage c and
a worm gearing with the same rotated in brackets on the carriage similarly as the
nut dis rotated.
for
The worm shaft & may be driven from the shaft a in any suitable manner,
instance by an excentric, pawl, and ratchet wheel or a worm and wormwheel, and
train of change wheels, but by preference I rotate the shaft by means of a friction
dise g keyed upon one end of the shaft e and a friction pulley h adjustable in its
position on a side shaft h', which is carried in adjustable bearings and rotated
by the shaft a through a pair of bevil wheels m m. By setting the pulley / nearer
to or farther from the centre of the disc, the speed of the shaft e² relatively to the
shaft a can be varied as required so as to draw the presser back for each revolution
of the shaft a for a distance equal to the thickness of one layer of warp wound
on, and by setting the pulley to one or the other side of the centre of the disc,
the presser can be drawn back while the shaft a is run forward or backward for
reversed warp sections.
For winding a
"trial section "I arrange a shaft n supported in brackets n¹ n² to
which a lever o with pressbowl o¹ is fixed underneath the section block and a
lever with weight pat any convenient place, which holds the pressbowl against
the warp while the latter is wound on and the section filled up to a mark turned on
the flanges a¹ a². The number of revolutions made while doing this is recorded by
a counter arranged and actuated from the shaft a in any ordinary manner used
for this purpose, and according to the indicated number the pulley is set to a
corresponding number marked on the shaft h', these marks being found by calculation
and corrected by trials, so that the pressbowl f is drawn back for the same distance
during the same number of revolutions when the winding is continued and the
section filled.
The pressbowl o' is then put out of action by depressing the treadle o³ on lever o,
a ratchet wheels fixed on the shaft n and a catch s' moveable on a stud fixed to
the frame holding the lever o in its depressed position, and the presser f² is brought
forward against the warp by the handwheel 3, the spindle fixed in the presser
and the winding continued.
Some other arrangements described in my Provisional Specification have been
purposely omitted from this Complete Specification.
.
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 :-
Firstly. In sectional warping machines moving the presser on a straight line
passing through the centre of the winding shaft for an equal distance for each
revolution of said shaft by means of a screw spindle and a nut rotated from said
shaft or of their equivalents, substantially as hereinbefore described.
Secondly. In sectional warping machines the arrangement of a screw spindle (✓)
carrying the presser and press bowl and threaded through a nut (d) rotated in a
laterally adjustable carriage (c) by means of a wormwheel and worm or their
equivalents from a shaft (e) rotated through gearing from the warping shaft (a)
combined with means for preventing the presser from turning and for locking and
unlocking the screwspindle to or from the same, substantially as hereinbefore
described and illustrated by the drawings.
Thirdly. In sectional warping machines the arrangement of an adjustable friction
pulley () on a shaft rotated by gearing from the warping shaft and a friction
disc (g) fixed on the end of the shaft from which a screw spindle or its equivalent
carrying the presser receives its motion substantially as hereinbefore described and
illustrated and for the purposes set forth.
