PROVISIONAL SPECIFICATION.
Improvements in Machinery for Winding, Doubling, and
Twisting Yarn.
We, FRANK ASHWORTH HOLT, of Atlas Iron Works, Molesworth Street, Roch-
dale, in the County of Lancaster, Machine Maker, ALFRED SEELEY, of 34, South
Street, Rochdale aforesaid, Traveller, and GRINDROD KERSHAW, of 64, Clement
Royds Street, Rochdale aforesaid, Draughtsman, do hereby declare the nature of
this invention to be as follows:-
Our invention relates to improvements in machinery for winding, doubling
and twisting yarn, and the object of our invention is to economise space and
labour.
In carrying out our invention we construct a suitable frame and set out the
winding on spindles in several rows, one above and behind the other, so as to
economise space and labour; the yarn to be wound on the spindles may be in
the form of a chain, ball or beam warp, or several beams, or it may be mounted
in a creel. The winding on spindles are driven positively or by friction and
the yarn may be wound upon Hanged bobbins or parallel or other tubes.
When winding yarn on Hanged bobbins we may use a differential motion for
varying the speed of the winding on spindles or varying the speed of the delivery
rollers or other delivery of yarn to the spindles, while for building bobbins with
one or both ends tapered on to tubes a diminishing lift motion, in addition to
the differential motion, where one is employel, would be required.
In one arrangement we employ a stationary spindle fixed in the lifting rail and
supported by a bolster as usual, near the middle; on the bolster is mounted the
driving wharve with a friction surface upon which rests a second friction sur-
face carrying a flyer with one or two legs; to the spindle above the wharve is
secured a stop collar to determine the position of the bobbin, tube or quil.
When the bobbin, tube or quil is secured to the spindle, the drag is given
entirely by the flyer but if desired, the drag can be divided between the flyer and
the bobbin, tube or quil by making a frictional contact between either of these
and the spindle.
As an alternative we might drive the spindle, in which case, the flyer could
be driven either positively or by friction and when the spindle is driven, a ring
and traveller, in place of the flyer, might be employed to put in the twist.
When doubling on the frame, two ends are placed and twisted on to each
spindle, and any other number of ends can be twisted in the same manner.

Twisting Yarn.
We, FRANK ASHWORTH HOLT, of Atlas Iron Works, Molesworth Street, Roch-
dale, in the County of Lancaster, Machine Maker, ALFRED SEELEY, of 34, South
Street, Rochdale aforesaid, Traveller, and GRINDROD, KERSHAW, of 64, Clement
Royds Street, Rochdale aforesaid, Draughtsman, 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:-
Our invention relates to improvements in machinery for winding, doubling
and twisting yarn, and the object of our invention is to economise space and
labour.
In carrying out our invention we construct a suitable frame and set out the
winding on spindles in several rows, one above and behind the other, so as to
economise space and labour; the yarn to be wound on the spindles may be in
the form of a chain, ball or beam warp, or several beams, or it may be mounted
in a creel.
In the accompanying three sheets of drawings-
Figure 1 is a front elevation, and Figure 2 a cross section of our improved
machine.
Figure 3 is a side elevation, Figure 4 an end elevation and Figure 5 a plan
of the diminishing lift motion which we may employ according to our present
improvements.
Figure 6 is a sectional elevation of a winding on spindle made according to our
improvements.
Referring first to Figures 1 and 2 which illustrate the general arrangement
of the machine, designates the frame, 6 the winding on spindles c the spindle
rails, the lifting rails, e the thread guides, f the pokers, ŷ the tin drums and
h the heart cam, for actuating the lifting motion. The heart cam h is driven
from the bottom tin drum g by the gears 1 and 2 chain wheel 3 chain 4 chain
wheel 5 and gears 6 and 7 or by other suitable driving gear.
As indicated in the drawings the spindles b are arranged in rows, each succeed-
ing row, after the front and lowest row, being placed higher and further back.
The yarn to be wound on the spindles bis drawn from chain, ball or beam
warps or from cops, bobbins or cheeses mounted in a warping creel and passes
through a nest of delivery rollers through the guides e on the lifting rails to
the spindles which may be driven in any convenient manner, as for example, by
bands from the tin drums g as shown.
When winding yarn on bobbins with two flanges we may use any suitable
differential motion such as a driving belt traversed along a pair of cones or a
friction disc and adjustable bowl or like mechanism for varying the speed of
the driven winding on spindles bor varying the speed of the driven delivery
rollers while for building bobbins with one or both ends tapered on to tubes
a diminishing parallel lift motion, in addition to the differential motion, or
equivalent arrangement hereinafter described, would be required.
In Figs. 3, 4 and 5, we illustrate a convenient arrangement of diminishing
motion for the purposes of our invention but we do not wish to confine ourselves
to this arrangement as any other suitable diminishing motion in conjunction with
a parallel lift motion may be employed. The heart cam h works upon an anti-
friction roller 8 mounted upon the side of a double lever m which is fulcrumed
at 9 on a pedestal n and has fitted in it a screw o upon which is fixed a ratchet

page_text: wheel p. A pawl lever q is fulcrumed upon the end of the screw o and is held
normally in the horizontal position by a pin or stop 11 fixed in the end of the
lever m above the tail of the pawl lever 7. A spring pawl is pivoted on the
pawl lever q to the other end of which is pivoted a screwed studs which passes
freely through a hole in the bracket t. On the screwed studs are threaded two
sets of locknuts 12 and 13 respectively by which the upward and downward
movements of the studs s are limited. A nut u is mounted on the screw o and
this nut is fitted in longitudinal slideways in a lever which is fulcrumed at 14
on a pedestal w and at the other end has connected to it the lifting chain which
passes over a guide pulley 15 to a quadrant arm 18, see Figs. 1 and 2, fixed on
the axis of a pulley 17 the under side of which has connected to it one end of a
strap 18 secured at the other end to the upper side of the pulley 19. On the
axes of the two pulleys 17 and 18 are fixed the lifting levers 20 upon which
the pokers frest and by which they are lifted.
In operation, as the heart cam h is rotated, it comes upon the roller S and
depresses the double lever m which in turn depresses the lever so that the lifting
chain turns the connected pulleys 17 and 19 raises the levers 20 and thereby
lifts the pokers f with the lifting rails d and thread guides e.
As the heart
cam recedes from the roller 8 the weight of the lifting rails, thread guides.
pokers and other parts, raises the levers m and as the lifting motion descends.
During the downward movement of the lever m the ratchet wheel p and pawl
lever also move down with their relative positions unchanged until the upper
pair of locknuts 12 reach the top of the bracket t when the downward movement
of the pawl lever being checked the further downward movement of the lever m
causes the spring pawl to act upon and turn the ratchet wheel pa tooth or
teeth, thereby turning the screw and traversing the nut u and so altering the
position in its slide ways in the lever whereby the movement of the lever v
and the lift of the pokers is diminished at each rotation of the cam / so long
as the pawl remains in gear with the ratchet wheel p.
We have shown in Figs. 3, 4 and 5 the diminishing motion set for building
bobbins with both ends tapered; if it is desired to build the bobbins square
at one end and taper at the other we should set the levers m, v, with their longi-
tudinal centre lines parallel, as shown in Figs. 3, 4 and 5, and lower or raise
the centre of the cam and place it so that the heel or the toe of the cam
rests upon the bowl S when the machine is set. In the first case bobbins will
be built with a flat bottom and taper top and in the other case with a taper
bottom and flat top.
This same motion can be applied for building bobbins flanged at both-ends
and in order to suit any variation in width between the flanges the position of
the nut u which by the cam h controls the traverse of the chain, is adjusted
and set by turning the screw o, when the pawl is thrown out of gear with the
ratchet wheel and the lift of the rails & remains constant.
Instead of a differential motion for varying the speed of the driven winding
on spindles b we may employ any suitable construction of spindle and drive it
or the bobbin or equivalent thereon or both spindle and bobbin by any suitable
arrangement of frictional driving in order to admit of "slip" caused by the
drag or tension of the yarn and so compensate for the increasing diameter of the
yarn as it is wound on.
Instead of employing driven winding on spindles and a differential motion or
an equivalent arrangement as above described we may employ driven flyers and
stationary spindles carried in lifting rails.
In one arrangement each spindle is fixed in a lifting rail and is supported
near the middle by a bolster 21 see Fig. 6, carried in a bolster rail 22 as usual;
on the bolster 21 is mounted the driving wharve 23 with a friction surface upon
which rests a part 24 with a second friction surface and carrying a flyer 25 with
one or two legs; to the spindle above the wharve 23 is secured a stop collar 26
to determine the position of the bobbin, tube or quill 27 which is placed on the

page_text: spindle b. When the bobbin, tube or quill is secured fast upon the spindle,
the drag is given entirely by the flyer 25; but if desired the drag can be divided
between the flyer 25 and the bobbin, tube or quill by mounting the bobbin, tube
or quill 27 loosely upon the stationary spindle and making a frictional contact
between either of these and the upper surface of the stop collar 26.
When doubling we may drive each spindle 6 in which case the flyers would be
driven either positively or by friction and when the spindles are driven rings
and travellers, in place of flyers, may be employed to put in the twist.
When doubling two or more ends are placed and twisted together on to each
spindle.
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: -
An arrangement and combination of parts substantially as herein described and
as illustrated by the accompanying drawings for winding flanged bobbins or
bobbins with one or both ends tapered from chain, ball or beam warps or from
cops, bobbins or cheeses mounted in a warping creel.
