PROVISIONAL SPECIFICATION.
Improvements in Machinery for Spinning, Doubling, and Twisting
Fibrous Material.
We, SAMUEL EDWARD ASQUITH, of 7, Grange Terrace, Allerton, near
Bradford, in the County of York, Mechanic, MARK LEACH, of 289, Kensington
Street, Bradford, aforesaid, Machine Maker, and ALBERT PRIESTLEY, of
Southgate, Bradford, aforesaid, Machinery Merchant, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in apparatus for spinning, doubling and
twisting fibrous material.
For this purpose we employ a hollow spindle carrying a hollow cylinder open
at the top and exceeding the length of and more than twice the diameter of the
full bobbin, cop, pirn or tube to be spun. A twisting spindle arranged to be
independently driven, is passed through the hollow spindle in the said cylinder and
is provided with an eye, or its equivalent at the top through which the yarn to be
spun or twisted is passed. A disc or projection, preferably carried by a sleeve
between the hollow spindle and the twisting spindle is mounted upon the twisting
spindle in such a manner that it is caused to revolve with said spindle but it is free
to be moved longitudinally thereon. This disc or projection is provided with an
eccentric vertical stud or projection carrying two horizontal arms which may be
coupled together. These arms are provided with a spring or springs tending to
press them towards the internal periphery of the said cylinder. The ends of these
arms are formed and adapted to hold a spindle or the like, which may carry a
bobbin or tube to receive the yarn being spun and the said spring or springs keep
it in contact with the internal periphery of the cylinder. A spring stud may be
employed instead of said fixed stud and arms.
In operation the cylinder is driven at a different speed to the twisting spindle
and the yarn passes from the twisting spindle to the bobbin or its equivalent and
is wrapped around it by the rotation of the bobbin carried by it, or the yarn
thereon, bearing against the internal periphery of the cylinder.
To wind the yarn helically from end to end of the bobbin or its equivalent any
suitable "lifter" motion may be provided to raise and lower the cylinder and bobbin,
or the twisting spindle may be raised and lowered for that purpose.
The "doffing" may be effected by lifting the bobbin or its equivalent out of
the cylinder or the cylinder may be made removable or to slide longitudinally, or
an opening may be made in it for this purpose.
The front rollers are preferably mounted above the twisting spindle and as
close to it as practicable so that the yarn passes directly from the rollers to the
spindies.
Instead of making the herein mentioned cylinder perfectly cylindrical it may be
made more or less conical or otherwise modified in form.

Fibrous Material.
We, SAMUEL EDWARD ASQUITH, of 7, Grange Terrace, Allerton, near
Bradford, in the County of York, Mechanic, MARK LEACH, of 289, Kensington
Street, Bradford aforesaid, Machine Maker, and ALBERT PRIESTLEY, of
Southgate, Bradford, aforesaid, Machinery Merchant, 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 improvements in apparatus for spinning, doubling and
twisting fibrous material.
To fully describe our invention reference is made to the accompanying sheet of
drawings forming a part of this Specification in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, represents an elevation of a spindle fitted with our improvements.
Figure 2, represents a vertical section of the same.
Figure 3, represents an elevation partly in section of a modified arrangement
for spinning or winding the yarn in the form of a "pirn."
Figures 4, 5 and 6 are detail views hereinafter referred to.
In Figures 1 and 2 the twisting spindle A is mounted in a foot rail A 2 and
bearing rail A 3 and extends up through the lifter plate B and the sleeve C into
the cylinder D. A driving wharle A4 is fixed on this spindle and an eye a is
made through the top and the material to be spun or twisted is passed through
this eye. Figure 6, represents a view of the top of the spindle looking at right
angles to Figure 1.
The front rollers feeding the material to the spindle are preferably mounted
immediately above the twisting spindle so that the yarn passes directly from these
rollers to the spindle.
The sleeve carries a disc C 2 at the top upon which the eccentric stud C3 is
rigidly fixed. The top of this stud is bent over to form a top bearing C 4 for the
rod E and the bottom of this rod has a bearing in or is centred in the disc C2.
This rod is provided with two arms E 2 and E3. The arm E 2 is made with a
fixed pin or centre E 4 to receive the bottom of the bobbin F or its equivalent
whilst the arm E3 is fitted with a spring pin or centre E 6 to engage the top of
the bobbin. The spring E7 normally keeps the pin E 6 in the position shown but
it allows the said pin to be pressed upwards to admit or release the bobbin.
Figures 4 and 5 represent a separate elevation and a plan view of said disc and
parts connected to it on a larger scale.
The bobbin may be mounted upon a spindle held between the centres E4
and E 6 or the yarn may be spun directly on to a suitable spindle mounted in this
way or on to a paper tube or its equivalent placed upon this spindle.
The cylinder D is provided with a hollow spindle D2 fitted in a bearing G
formed in the rail G 2 and the wharle D3 is fixed on the bottom of D2. A
spring C7 is provided arranged to press the arms E 2 and E3 outwards and keep
the bobbin F and yarn wound thereon pressed against the internal periphery of
the cylinder D which pressure when the apparatus is in operation is increased by
centrifugal force. The twisting spindle A is formed with a flat or key-way a 2
down one side and the key a 3 (Figure 2) fitted in the top of the sleeve C
engages said flat or key-way and causes the sleeve and disc thereon to revolve
with the twisting spindle. The bottom of the sleeve passes through the lifter
plate B and a collar C5 formed upon the sleeve rests upon the lifter plate whilst
an adjustable collar C 6 on the bottom of the sleeve bears against the underside of

page_text: the lifter plate. This arrangement leaves the sleeve perfectly free to revolve but
at the same time causes it to rise and fall with the lifter plate.
In operation the twisting spindle and disc carrying the bobbin or its equivalent
are driven at a suitable speed for spinning and the yarn, represented by the broken
line e Figure 2, passes from the eye a on to the bobbin whilst the cylinder D is
driven at a suitable speed to reduce the "drag" to the required extent. The lifter
plate is operated by any ordinary mechanism to traverse the bobbin up and down
from the position shown in Figure 1 to that shown in Figure 2 and vice versa.
Instead of moving the sleeve C up and down to wind the yarn from end to end
of the bobbin the twisting spindle may be raised and lowered for that purpose by
any suitable lifter mechanism.
In Figure 3 the upper end d of the cylinder is made conical and the inclination
of the conical portion is such that it bears with approximate uniformity against
the yarn when wound in the form of a "pirn."
pirn
"
e 2 and the other
In this arrangement two lifter motions are required. One lifter motion is
applied to the foot rail A 2 and raises and lowers the spindle A in the manner
required to wind the base or commencement of the "
"lifter" motion operates the plate B and gradually lowers the sleeve whilst the
remainder of the pirn is wound. In other respects this arrangement is similar to
the arrangement previously described.
To make the cylinder lighter it may be cut away in any manner desired so long
as a sufficient portion of the top is left intact.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :
The general construction and arrangement of spinning, doubling and twisting
mechanism substantially as herein shewn and described.
