PROVISIONAL SPECIFICATION.
Improvements in or relating to Machines for Winding Thread,
Cotton, or the like into Cops or upon Spools.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford, in
the County of Stafford, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object improvements in machines which are used for
winding thread so as to form cops to be used in the shuttles of sewing machines.
It is often necessary and generally desirable that these cops should be of uniform
size when wound.
°
To ensure this result I provide a winding machine with an automatic arrange-
ment such that when a cop becomes of the desired diameter the spindle driving
gear is thrown out of action so as to stop the spindle and prevent further thread
being wound.
I cause the thread as it winds upon the spindle gradually to lift a frame until a
spring or weighted catch is released which withdraws a clutch or friction gear
from engagement with its driver.
I mount a roller or weight above the spindle upon which the thread winds to
ensure its being laid uniformly thereon and I employ an arrangement consisting
of a grooved wheel, friction washers, screw stud, nut and spring for applying
tension to the thread on its passage to the winding spindle.
If it is desired to wax the thread I employ a wax pot which is provided with a
wax stripper and heated by steam from a boiler or by hot water in a tank, the
beat being derived from gas burners or other source, provision being also made
for supplying the water and regulating the same and for inserting and removing the
wax-pot.
I provide gas jets for keeping the spindles on which the thread is wound and
other parts, sufficiently hot to prevent setting of the wax during the winding
operation.
The machine may have one or other desired number of spindles and may be
arranged upon a column or stand on a bench or table and be suitably driven by a
belt or otherwise.

Improvements in or relating to Machines for Winding Thread,
Cotton, or the like into Cops or upon Spools.
I WILLIAM HENRY DORMAN, of The Hawthorns, Newport Road, Stafford, in
the County of Stafford, Engineer 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 has for its object improvements in machines which are used for
winding thread so as to form cops to be used in the shuttles of sewing machines.
It is often necessary and generally desirable that these cops should be of uniform
size when wound.

page_text: To ensure this result I provide a winding machine with an automatic arrange-
ment such that when a cop becomes of the desired diameter the spindle driving
gear is thrown out of action so as to stop the spindle and prevent further thread
being wound.
I cause the thread, as it winds upon the spindle, gradually to lift a frame until a
spring or weighted catch is released which withdraws a clutch or friction gear
from engagement with its driver. I mount a roller or weight above the spindle
upon which the thread winds to ensure its being laid uniformly thereon and I
employ an arrangement consisting of a grooved wheel, friction washers, screw stud,
nut and spring for applying tension to the thread on its passage to the winding
spindle.
If it is desired to wax the thread 1 employ a wax pot which is provided with a
wax stripper and heated by steam from a boiler or by hot water in a tank the heat
being derived from gas burners or other source provision being also made for
supplying the water and regulating the same and for inserting and removing the
wax pot.
I provide gas jets for keeping the spindles on which the thread is wound and
other parts sufficiently hot to prevent setting of the wax during the winding
operation.
The machine may have one or more spindles and may be arranged upon a
column or stand on a bench or table and be suitably driven by a belt or otherwise.
My invention is illustrated by the accompanying drawings in which.
Fig. 1. is a front view of the machine.
Fig. 2. is a plan.
Fig. 3. is a side view.
Fig. 4. is a vertical section of the wax pot and
Fig. 5. is a horizontal section, both enlarged.
Figs. 6 & 7. are enlarged side views of the head.
Figs. 8 & 9. are front views and
Figs. 10 & 11. plans of the same.
Fig. 12. is a further enlarged view of the spindle.
Figs. 13. & 14. are views of one thread washer much enlarged and
Figs. 15 & 16. are views of the other thread washer.
Figs. 17 & 18. shew a much enlarged cop of wound thread and
Figs. 19 & 20. shew a wound spool or reel.
A. (Figs. 1. 2 & 3.) is the base B the column and C the entablature of the
machine upon which any desired number of heads D. D¹ D' D³ may be arranged.
(Four are shewn in the drawings). Along the back of the machine is the driving
shaft E carried in bearings F. F¹ F². It is driven by the pulley G and provided
with an idle pulley G'. The driving shaft E is furnished with friction cones
H. H H H one to each head and these are arranged to engage at the proper
times other friction cones 1. 1 I 13 which are inounted on the winding spindles
J. J1 J2 J³.
The cops K. KK2 K3 are wound upon the front ends of these spindles and
when desired to be waxed the threads L. L'L L³ are passed through wax
pots M. M' M² M³.
The balls of thread N. N' N° N³ are conveniently carried on shelves O. O¹ and
on their way to the waxpots the threads are passed once or twice around tension
trucks P. Pi P P³ which are mounted in an ordinary manner on studs Q. QQQ
and have an adjustable frictional resistance to turning applied to them by means of
springs R. R R R³ and nuts S. S' S² S³.
The enlarged views of the head (Figs. 6 to 11) will better illustrate the action of
the machine. E is the driving shaft. H and I a pair of the friction cones Ja
spindle and Kone of the cops of thread before referred to. The spindle J is
carried in the bearings a. a' and at its front end a² is tapered down (see also
Fig. 12) so that the cop K (Figs. 17 & 18) will readily draw off when wound.
The spindle J has an enlarged portion a³ which collars against the face of the

page_text: bearing a so as to prevent backward movement and it is provided with feathers a'
on which the cone I may slide longitudinally. A collar a is secured on the rear
end of the spindle J and a spring a is arranged to press the cone I out of
engagement with its fellow cone H when the winding spindle J is required to;be
out of action.
The taper end of the spindle J is supported in bearings b. 6' formed in a
frame which, so that it may be moved forward into the position shewn in
Figs. 7. 9 & 11 for the purpose of pushing the wound cop off the spindle, is made
with a portion in the form of a rack 63 which is guided so as to be free to slide.
longitudinally, and parallel to the spindle J, in the head D.
The rack engages the pinion which is mounted on a shaft b³ carried in a
bearing formed in the head D. A lever mounted on the shaft 6 serves to
operate the frame 62 and is provided with an adjustable weight 68 the object of
which is to press the cone I into engagement with the cone H so as to keep the
spindle J running until the cop is fully wound as follows.
The weight through the pinion 64 and rack 6 (see Figs. 6. 8 & 10) presses
the frame towards the head D. Carried upon the frame 62 is another frame c
an arm of which bears against a catch at one end of a sliding bar so as
to press it backwards. The bar is guided in the head D in bearings c³ and
has at its rear end a forked clutch arm which engages between collars
formed ou the cone I. The weight overpowers the resistance of the spring a
previously referred to and maintains the driving contact between the cones H
and I.
In order that all cops shall be wound of equal diameter an arrangement is made
for stopping the spindle J when the required amount of thread has been wound..
The roller is mounted in the frame c already referred to and rides upon the
thread as it winds so as to maintain its even winding. The frame c is hinged to
the frame upon a pin d' so as to allow the increasing diameter of the cop to
raise the roller d which in rising lifts the arm e already referred to until it is clear
of the catch at the end of the bar which then being no longer held by the
weight allows the spring a to move the cone I out of engagement with the
cone H. The bar of course being moved forward also.
To prevent friction of the thread against the bearings b. washers or collars
are provided (see Figs. 12 to 16) which revolve with the spindle J. The
washer e is furnished with a slot to receive the end of the thread to be wound
and it is driven by a peg e in the spindle J which enters the hole e provided in
the collar e which is secured upon the washer e. The other washer is provident
with a square hole' by which it is driven the extreme end ƒ³ of the spindle J
being made square to suit.
A spring y is provided upon the frame & which acts upon a square portion gl of
the frame so as to retain it in the upright position as shewn in Figs. 7. 9 & 11
and also when in the position shewn in Figs. 6. 8 & 10 to assist in pressing the
roller down upon the thread.
Fig. 4 is a vertical section and Fig. 5 is a horizontal section of the wax pot.
The case stands upon the base A and surrounds the boiler h' so as to retain the.
heat from the burner ². The wax is placed in the pot 43 which is placed. within
the boiler and surrounded with the steam from the water. The cover h is held
in place by the buttons and a joint ring of indiarubber or other suitable
material is interposed between the flange of the pot and another flange h
formed upon the boiler to prevent the escape of the steam. A tube his formed
at one side of the boiler which is open to the air at its top and to the boiler
bottom at its lower end for the purpose of putting water in the boiler without
disturbing the wax pot and a cock ho is provided at which when open the water
will flow out when the boiler h¹ is sufficiently full.
The wax stripper consists of an india-rubber disc i with a small vertical hole i
through its centre through which the thread L is passed and more or less
compression is put upon the disc i by means of a screw gland which allows of

page_text: more or less wax being retained by the thread. A wire is placed within the wax
pot under which the thread L passes.
The machine is operated in the following manner. Balls of thread N. N' N2 N³
are placed upon the shelves O and O' the thread L is led around the tension
truck P down into the wax pot ³ under the wire up through the stripper i and
the end inserted in the slot el of the washer e. The shaft. E being in revolution
the lever is brought forward into the position shewn in Figs. 6. 8 & 10
and the roller d is lowered upon the spindle a². The weight 8 presses the arm el
against the catch and the winding commences. The thread L under the action
of the roller d is uniformly laid to and fro between the washers e and each
extra layer raising the roller and the arm higher until the latter releases
the catch when the spring a pushes the cone I out of engagement with the
cone H and the spindle J stops.
The lever is then turned over backwards and the cop K thrust off the spindle.
The roller being also raised (see Figs. 7. 9 & 11) so as to be out of the way for
inserting the next end of thread when cut off from the wound cop.
me
The rack and gear arrangement for pushing the wound cops off the spindles is
similar to that described in Specification of Letters Patent granted to
No. 23267 and dated December 17th 1892, while the wax stripper and certain
features of the wax pot are similar to such described in the Specification of Letters
Patent granted to F. A. Hinks and W. H. Dorman No. 3504 and dated
March 8th 1887.
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. The combined winding machine consisting of the frame, the driving gears,
the spindles, the automatic stopping arrangements, the rollers, and the tension
devices as described and illustrated and for the purpose specified.
2. In a machine for winding thread into cops or upon spools the use of a roller
which rides upon the thread as it is wound so as to ensure the same being uniformly
laid.
3. In a wax pot or apparatus for applying hot wax to thread the use of a boiler
provided with a tube open to the air above and to the bottom of the boiler below
by which water may be supplied without disturbing the wax pot and provided also
with a cock to regulate the height of the water.
