PROVISIONAL SPECIFICATION.
Improvements in the Machines known as Sectional Warping and
Beaming Machines.
I, JOHN HOWARD STOTT, of Baron Street Works, Rochdale, in the County of
Lancaster; Machine Maker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the machines known as sectional warping and beaming
machines.
"
My invention consists in arrangements by means of which I cause the tension of
the yarn or thread of each "section" to be uniform throughout the "section."
According to my invention the yarn or thread to be wound upon the "section
is delivered by means of a pair of rollers between which the yarn or thread passes.
Supported by the yarns or threads while they are passing from the rollers above
mentioned to the "section block" upon which they are wound, is a pulley which is
suitably connected to a friction bowl or roller which imparts motion to the "section
block by means of a plate, pulley or disc. The friction bowl or roller receives
rotary motion from any suitable part of the machine. When the diameter of the
66 section "increases the frictional contact between the friction bowl or roller and
the plate, pulley or disc above mentioned will be decreased and the "section"
wound slower until the determined length has been wound on the "section block."
The tension will thus be caused to be the same in all succeeding "sections"
which have the same length and "counts " of yarn or thread and number of
< ends."

COMPLETE SPECIFICATION.
Improvements in the Machines known as Sectional Warping and
Beaming Machines.
I, JOHN HOWARD STOTT, of Baron Street Works, Rochdale, in the County of
Lancaster, Machine Maker, 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 machines known as sectional, warping and beaming
machines.
"
My invention consists in arrangements by means of which I cause the tension
of the yarn or thread of each "section to be uniform throughout the "section."
According to my invention the yarn or thread to be wound upon the "section
is delivered by means of a pair of rollers between which the yarn or thread passes.
Supported by the yarns or threads while they are passing from the rollers above
mentioned to the "section block" upon which they are wound is a pulley which is
suitably connected to a friction bowl or roller which imparts motion to the "section
block" by means of a plate pulley or disc. The friction bowl or roller receives
rotary motion from any suitable part of the machine.
When the diameter of the "section" increases the frictional contact between the
friction bowl or roller and the plate, pulley or disc above mentioned will be decreased
and the section wound slower until the determined length has been wound on the
"section block."

page_text: The tension will thus be caused to be the same in all succeeding sections which
have the same length and "counts of yarn or thread and number of ends.
In the accompanying drawings
"
Fig. 1 is a side elevation, Fig. 2 an end view, and Fig. 3 a plan illustrating a
sectional warping and beaming machine constructed according to my invention
and serving to illustrate the manner in which my invention may be carried into effect.
Fig. 4 is a side elevation and Fig. 5 a plan serving to illustrate certain parts of
the machine more clearly than Figs. 1, 2, and 3.
The same letters of reference are applied to corresponding parts in all of the
figures.
In the accompanying drawings a is the section block upon which the yarns or
threads A which are drawn from the creel as is usual are to be wound into a
"section." The section block a illustrated in the drawings is what is usually known
as the "expanding block” but a block of any other suitable kind may be employed
to receive the yarns or threads A to form the "section."
The yarns or threads A. which on their way from the creel to the sectional warping
machine pass through a vee reed
c by means of which they are brought as close
together as may be desired are caused to pass beneath a roller d over a roller e
beneath a roller f and to pass over a measuring roller 9 from which they pass to
the sectional block a. The axles of the rollers d and are mounted in bearings
formed in the frames h¹, 12 of the machine and the axle of the roller e passes at its
ends into slots e¹ formed in the frames h¹, h² of the machine, in which slots e¹ the
said axle may be moved upwards and downwards and by which slots the said axle
is guided while being so moved. Upon the axle of the roller e are suspended
hooks e supporting a bar e upon which weights et of suitable mass may be placed
in order that the roller e when bearing upon the rollers d, f, may bear thereon with
sufficient pressure.
When the roller is caused to revolve as will be hereinafter
explained such roller and the rollers e, d, acting in conjunction with it will draw
the yarns or threads A. from the creel aforesaid and deliver them to the "section
block" upon which they are to be wound. The rollers d, e, f thus constitute what
are ordinarily designated calender rollers. In the Provisional Specification filed in
respect of my application for Letters Patent I referred to a pair of rollers being
employed to draw the yarns or threads from the creel and deliver them to the section
block but I find it desirable to employ the arrangement of three rollers d, e, f in
order to be able to obtain the required hold upon the yarns to enable them to be
uniformly drawn from the creel and delivered to the section block a. The section
block a which is mounted upon a shaft i mounted and capable of being revolved in
suitable bearings formed in the frames h, h¹ receives rotary motion by means of a
plate pulley or discj to which a rotary motion is imparted by a friction bowl or
roller mounted so as to be capable of being slidden longitudinally upon while
being turned by a shaft m mounted and capable of being rotated in suitable
bearings formed in the frame h¹ and in a bracket h³ secured thereto. Motion is
transmitted to the shaft m by means of one or other of the bevel wheels n¹
according as the shaft m is to be revolved in the direction indicated by the arrow B
or in the opposite direction. The bevel wheel o which transmits motion to the
bevel wheel 'n or the bevel wheel n' as the case may be is mounted fast upon a
shaft P which is mounted in suitable bearings formed in the frames h, h¹ and is
provided with a fast pulley 9 to which rotary motion in the direction indicated by
the arrow C may be imparted in any suitable manner and with the usual loose
pulley g'. Fast upon the shaft p is mounted a worm wheel which gears into or
engages with the teeth of a worm wheel & mounted upon a shaft t mounted and
supported in suitable bearings formed in the cross frames t¹, t. Fast upon the
shaft is mounted a bevel wheel u the teeth of which gear into or engage with the
teeth of a bevel wheel v mounted fast upon the axle of the roller / The bevel
wheels n, n' are mounted fast upon a sleeve n³ capable of being slidden longitudi-
nally upon the shaft m but incapable of being rotated thereon which sleeve n³ is
provided with a groove n* into which engages a stud w³ secured in one end of a
n,

page_text: lever wo mounted upon a pivot to secured to the frame ¹ to which lever wis
connected one end of a rod a bent so as not to come in contact with the friction
bowl or roller k, the other end of which rod x passes through a slot formed in the
frame h' which frame is provided with a part upon which either of two
notches, formed in the rod a may be caused to hook so that the bevel wheel n
or the bevel wheel n' as may be required may be caused to be in gear with the
bevel wheel o. The measuring roller g is mounted in and supported by arms y
secured upon an axle z mounted and capable of being oscillated in bearings formed
in the frames h, h, 2. To the axle is secured an arm 2 provided with a stud 2.
which is mounted and free to turn in the arm 2 and is provided with a rectangular
portion which passes into and engages with a groove formed in the collar secured
to or formed with the friction bowl or roller k. The arm 2 may be provided.
with a jaw to embrace the collar secured to or formed with the friction bowl
or roller and two studs 2 may be employed instead of one stud 2. Upon the
axle z is also secured an arm 3 which is provided at its end with an eye 3ª
formed in a stud mounted and capable of being turned in the said arm 3..
Through the eye 3* which is rectangular in form passes a rectangular part.
formed on a rod 4 which at one end passes through a hole formed in the frame /
and is provided with screw threads capable of being screwed upon which is a nut 4°
provided with a handle 4". The nut 4° prevents the rod 4 from being moved in the
direction opposite to that indicated by the arrow D. At its other end the rod 4 is
provided with a head or collar 4" against which abuts one end of a spiral spring 5
which tends to push the eye 3* along the rectangular portion of the rod 4 in the
direction indicated by the arrow D and so tends to turn the axle and arms y
in
the direction indicated by the arrow E. By the handle 4 being turned in one
direction or the other the spring 5 may be caused to bear more or less upon the
eye 3 and so the tendency of such spring 5 to move the eye 3* in the direc-
tion indicated by the arrow D may be increased or diminished as may be necessary
or desirable from time to time. The shaft m is provided with a fly wheel m',.
and the blocks which surround the ends of the axle of the roller e and are
placed in the grooves el are connected to links 6 which at their upper ends
embrace excentrics 7" mounted fast upon a shaft 7 provided with a handle 7b by
means of which such shaft 7 may be turned so that the roller e may be removed
from the rollers and d or may be allowed to rest thereon. An arm 7 is secured
upon the shaft 7 in such position that when such shaft 7 is turned to remove the
roller e from the rollers d, and f such arm 7° will arrive against one of the parts 7d
in which the shaft 7 is mounted and so prevent such shaft 7 from being turned too
far and so keep the roller e removed from the rollers d, f, until the shaft 7 is again.
turned to allow the roller e to rest on the rollers d, f.
こ
When a "section" is to be wound the handle 7, is turned so as to raise the
roller e from the rollers and d and the handle 4* is turned so as to cause the lever
to turn in a direction opposite to that indicated by the arrow E and the yarns or
threads to form such section are taken from the creel and passed through the
heck c, beneath the roller d over the roller e, beneath the roller and over the
measuring roller g, and are secured to the section block a. The handle 7" is then
turned so as to allow the roller e to be supported by the rollers and d in order
that the yarns or threads may be securely held between the roller e and the rollers"
and . The handle 4* is then turned so as to cause the spring 5 to turn the arms y
in a direction opposite to that indicated by the arrow E until the yarns or threads
are submitted to the required tension. The turning of the handle 4* to submit the
yarns or threads to tension will cause the friction bowl or roller k to be brought
into and pressed in contact with the plate pulley or disc j. The shaft p being then
caused to rotate in the direction indicated by the arrow C by a strap or belt being
placed upon the fast pulley y the rod . is moved so as to cause either the wheel n
or the wheel n' to be placed in gear with the wheel according as the shaft i is to
be caused to revolve in the direction indicated by the arrow F or in the opposite
direction and after being moved into the required position the rod r is secured in
2)

page_text: the
such position by the notch r¹ or the notch as the case may be being hooked upon
the part. The section block a will then revolve and rotary motion will by
means of the worm wheel r, worm wheels, shaft t, and bevel wheels u and be
transmitted to the roller f which will cause the rollers e and d to revolve. The
rollers de and will then draw the yarns or threads A from the creel and deliver
them to the section block a upon which they will become wound and thus the
winding of the section will proceed. The rollers d, e, and f revolve with uniform
velocity during the winding of the whole "section" and the diameter of the
"section" gradually increases as the layers of yarn or thread are wound thereon
and thus there is a tendency for the yarns or threads to be wound
upon
" section
more rapidly than they are delivered by the rollers d, e, f unless the
section is caused to revolve less rapidly as it increases in diameter. The tendency
of the section to cause the yarns or threads A to be wound thereon more rapidly
than they are delivered by the rollers d, e, f, causes a slight increase in the tension
of such yarns or threads and the increase of tension acting upon the measuring
roller g causes the arms y to be turned in the direction opposite to that indicated
by the arrow E against the pressure of the spring 5 and so reduces the friction
between the friction bowl or roller k and the plate, pulley or disc j and allows the
friction bowl or roller k to "slip" upon the said plate, pulley or disc j and so allows
j
the section to revolve more slowly as it increases in diameter. If from any cause
the section should revolve more slowly than is necessary to preserve the required
tension of the yarns or threads A the spring 5 will turn the levers y in the direction
indicated by the arrow E until the required tension in the yarns or threads A has
been restored and in so turning the said levers y will cause the friction bowl or
roller to be pressed more forcibly against the plate, pulley or disc which will
then be caused to rotate more rapidly and so cause the yarns or threads A to be
more quickly wound upon the "section." Any tendency to an increase in the tension
of the yarns or threads A will cause the friction between the friction bowl or roller k
and the plate, pulley or disc to be diminished and any tendency to a diminution of
the tension of the yarns or threads A will cause the friction between the friction
bowl or roller and the plate, pulley or disc j to be increased and thus any
tendency to an increase or diminution in the tension of the yarns or threads A
between the rollers f and e and the "section" brings into action means by which it
is counteracted. The tension of the yarns or threads A between the rollers and e
and the "section" being thus prevented from varying remains uniform, during the
whole operation of the winding of the "section" and thus if after one section" has
55
"2
been wound, other "sections" containing yarns or threads of the same length and
66 counts and the same number of "ends are afterwards wound each of such
"sections" will be caused to have the same tension. As the tension upon the yarns
or threads being wound upon a "section" is uniform during the winding of such
"section" and the yarns or threads are drawn at a constant speed by the
rollers d, e, f from the creel no injurious tension is placed upon such yarns or
threads and thus the said yarns or threads do not become "stretched" while being
wound upon the "section."
The axle of the measuring roller g is provided with a worm wheel which actuates
a suitable measuring and marking apparatus 8 such as is usually employed in
sectional warping machines.
The movements which take place in the position of the roller g are not sufficient
to interfere with the proper working of the measuring and marking apparatus 8.
In place of mounting the measuring roller g upon the arms y I may place such
measuring roller g elsewhere and mount upon the arms y a pulley over which the
yarns or threads may pass on their way to the section block a.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a sectional warping and beaming machine the hereinbefore described

page_text: arrangements by means of which the tension of the yarns or threads forming
each "section is caused to be uniform throughout such "section" which
arrangements consist in a pulley or roller suitably connected to a friction bowl or
roller which imparts motion to the section block by means of a plate, pulley or
disc substantially as hereinbefore described and so that the tendency to an
increase or diminution in the tension of the yarns or threads causes a diminution
or increase of the friction between the said friction bowl or roller and the said
plate, pulley or disc.
2. In a sectional warping and beaming machine the hereinbefore described
combination and arrangement of parts consisting in the rollers d e and for pair of
rollers which deliver the yarns or threads at an uniform speed, the pulley or roller g
the arms y, 2 and 3 spring 5 friction bowl or roller k and plate, pulley or disc j all
arranged employed and operating in conjunction with each other and other
necessary parts for the purposes and substantially in the manner hereinbefore
described, with reference to and indicated in and by the accompanying drawings.
3. In a sectional warping and beaming machine the hereinbefore described
combination and arrangement of parts consisting in the roller or pulley g and
friction bowl or roller k connected together by suitable parts, so that when the said
roller or pulley g is moved by the yarn or thread or allowed by such yarn or thread
to be moved by a spring the friction between the said friction bowl or roller k and
the plate pulley or disc to which it imparts motion is decreased or increased for the
purposes and substantially in the manner hereinbefore described with reference to
and indicated in and by the accompanying drawings.
