I, PIETER NICOLAAS Hoos, Ropemaker, 's Gravenweg 262, Rotterdam, (Kral-
ingen), Holland, do hereby declare the nature of this invention to be as follows:―
This invention for improvements in spinning or twisting and winding
machines has for its object to provide improved means for driving the draft cap-
stans or pulleys from which the yarn is fed on to the reel.
The draft capstans are mounted in the winding flyer and rotated therewith, but
as they also require to be rotated independently about their own axes a separato
driving belt has hitherto been employed which operates through a spindle and
spur gearing to drive the draft capstans at the required speed.
Now according to this invention the draft capstans are driven exclusively from
the flyer, the additional pulley and spur wheels being dispensed with and as the
flyer and capstans are driven from one belt a more regular speed is insured than
could be attained hitherto owing to the slipping of the belts.
In carrying out this invention the end plate or head of the flyer is provided
with a bolster or sleeve on its outer face and on its inner face with a rectangular
bracket or plate, fixed thereto at right angles and supporting two fixed spindles
on which the draft capstans are mounted with their axes parellel with the end
plate of the flyer. A hollow spindle passing through the end plate of the flyer
into the bolster, where it is secured by a set screw, is formed near its inner end
with a worm which gears with worm wheels mounted co-axially with the draft
capstans and fixed thereto. The inner end of the worm spindle has a bearing
in a bracket fixed on the flyer head, which bracket has a hole and slit for the
yarn and a guide over which the yarn passes. The yarn passes through the
hollow worm-spindle, through the hole in the bracket, is wound crossways on the
draft capstans and then passes over a guide roller to the bobbin in the usual
way.
It will readily be seen that on the rotation of the flyer which is driven by a
belt at a regular speed, the draft capstans will also be driven through the worm
gearing at a regular speed which is entirely dependent on the speed of the flyer
and causes the yarn to be pulled with even tension on to the bobbin giving the
proper amount of twist and avoiding the production of overturned or curled work.
When a little slackness in the belt occurs the yarn will be slightly thicker but
the twist will be right for the size of the yarn.

I, PIETER NICOLAAS Hoos, Ropemaker, of 's Gravenweg 262, Rotterdam (Kral-
ingen), Holland, 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 for improvements in spinning or twisting and winding
machines has for its object to provide improved means for driving the draft cap-
stans or pulleys from which the yarn is fed on to the bobbin.
The draft capstans are mounted in the winding flyer and rotated therewith, but
as they also require to be rotated independently about their own axes a separate
driving belt has hitherto been employed which operates through a spindle and
spur gearing to drive the draft capstans at the required speed.
Now according to this invention the draft capstans are driven exclusively from
the flyer, the additional pulley and spur wheels being dispensed with and as the
flyer and capstans are driven from one belt an absolutely regular speed is insured
which could not be attained hitherto owing to the slipping of the belts.
In the accompanying sheet of illustrative drawings:
Fig. 1 is a part plan of a winding flyer fitted with yarn drawing mechanism
constructed according to this invention and Fig. 2 is an elevation of the same.
The end plate or head a of the flyer is provided with a bolster or sleeve bon
its outer face and on its inner face with a rectangular bracket or plate e fixed
thereto at right angles and supporting two fixed spindles on which the draft
capstanse are mounted with their axes parallel with the end plate a of the flyer
as shown. Worm wheels f are mounted co-axially with the draft capstans and
fixed thereto. The flyer a resting with sleeve in a bearing (not shown) rotates
round a fixed hollow spindle secured by the set screw in a fixed collar i which
adjoins the end of the sleeve b. The spindle g is provided with a worm k that
passes between and gears with the worm wheels f, the inner end of the spindle g
entering a bracket fixed to and rotating with the flyer head, which bracket has
a hole m and slit n for the yarn and a guide over which the yarn passes.
The yarn passes through the hollow worm-spindle g, through the hole m in the
bracket, over the guide o, is wound crossways on the draft capstans and then
passes over a guide roller to the bobbin in the usual way.
As the draft capstans and their worm wheels are rotated with the flyer about
the fixed spindle, the flyer being driven by a belt at a regular speed, it will
readily be seen that the draft capstans, being rotated about the worm, will also
be driven at a regular speed which is entirely dependent on the speed of the
flyer and causes the yarn to be pulled with a regular speed on to the bobbin,
giving the proper amount of twist and avoiding the production of overturned or
curled or too little twisted work.
When a little slackness in the belt occurs the yarn will be slightly thicker but
the twist will be just right for that size of the yarn.
Changing the twist in the yarn is effected by changing the size of the draft
capstans.
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
1. In spinning or twisting and winding machines the combination with the
winding flyer of a stationary worm, of worm wheels mounted on and inside the

page_text: flyer and gearing with the worm, and of the draft capstans fast with the worm
wheels and rotating therewith, substantially as described.
2. In spinning or twisting and winding machines the improved means for
driving the draft capstans substantially as described with reference to the
drawings.
