A Machine for Doubling, Twisting, and Skeining Threads of Textile
Material.
1, PERCY HADDAN of the firm of Herbert & Co., Patent Agents of 18 Buckingham
Street, Strand W.C. London in the County of Middlesex, Civil Engineer do hereby
declare the nature of this invention a communication to me from abroad by Edouard
Six of Tourcoing in the Republic of France Manufacturer and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
The object of this invention is to provide and combine in one machine, mechanism
for doubling twisting and skeining threads or yarns of any textile material.
Reference being made to the accompanying drawing. Fig. 1 is a side elevation,
Fig. 2 a front elevation and Fig. 3 a plan of the machine.
On a doubling machine of any suitable construction is arranged a device for
spinning or twisting the roving or the like delivered from said doubling machine and
winding it into skeins of desired size. The device aforesaid consists of a drum T
adapted to be revolved with great rapidity and of sufficient diameter and breadth to
receive the skein wound upon its periphery. Concentrically with said drum is
arranged an annular rail of a slightly larger diameter than the drum and on this rail
is a freely movable carriage of any convenient form C being preferably a small piece
of metal, the ends of which are bent up to engage bebind a flange on the annular
rail A. The doubled roving is passed directly between two condensing rollers Rand L
and thence through a ring 1) in the framework in the line of the axis of the drum T
through the carriage C to the periphery of the drum to which the end of the roving
is fastened. When the drum is turned the roving is wound thereon as delivered from
the condensing rollers being twisted more or less according to the difference between

page_text: the respective linear speed of the periphery of the drum and the delivery of the
roving.
The roller L is revolved by surface friction from the roller R and the latter is
driven by the gear G¹ G2 G3 G4 G5 from the main shaft.
To modify the twist of the yarn. the speed of delivery of the rollers R and L is
varied by employing gears G₁, G² of different proportions.
In the machine represented in the drawings H are the bobbins on which the slivers
are wound, the latter pass over an automatic stop mechanism the purpose of which is
to stop the machine in the event of the breakages of any one of the slivers. As a stop
mechanism 1 prefer to use a number of rods one suspended on or by each sliver and
guided in a box or frame without bottom, below the said frame revolves an endless
apron w provided with ribs or projections so that when a sliver breaks the rod
suspended thereby falls and comes into engagement with said apron w by which the
frame is oscillated on its trunnions, so as to release a detent I and permit the lever K
pivoted on a rod a to be moved backward by means of the spring S.
The lever K carries a projection Q which by said movement, is caused to ride under
and lift the pivoted frame S₁ in which the smaller condensing and drawing roller L is
journalled so that the latter is set out of action. The lever K is also connected by a
rod u to the lever u' pivoted at o and connected at its upper end to the angle lever V
of the fork V₁ so that the said fork is moved by the aforesaid movement of the
lever K so as to shift the strap h from the fast pulley E onto the loose pulley E¹ on
the shaft of the drum T and cause the stopping of said drum. Since however, the
momentum of the drum T is very great, I have arranged a friction brake j to enable
the drum to be quickly stopped when the strap his shifted onto the loose pulley.
This brake consists of a disc carried on two rods guided in the frame of the machine,
said disc adapted to be pressed onto the side of the drum T by springs
permitted by the movement of the lever u' which carries a wedge shaped end and
which usually holds the disc back from the drum. .
h
when
The strap passes around the pulley B on the main driving shaft and is tensioned
by pulley or roller such as p Fig. 1. The endless apron w is driven by strap and
pulleys n and m.
a
In order to enable a certain amount of yarn to be skeined, that is to say to be
wound on the drum, a suitable counter is provided such a counter being preferably
arranged to arrest the movement of the machine when the desired amount of skein
is made.
In the drawings, the shaft of the roller R carries a spur wheel e, a second spur
wheel el is arranged loosely on the shaft of the roller L and geared with the first a
third is geared with the wheel e¹ and fixed on a shaft carrying also a small drum
on which is wound several turns of a cord passing over a pulley down into a
cylindrical guide y and carrying at its end a piece of metallic wire or bolt for
engagement with the endless apron of the stop mechanism and so stop the machine in
the manner before described with regard to the breaking of the thread.
During the operation of the machine the rotation of the drum z unwinds the cord
and the wire descends until it is knocked by the ribs of the endless apron. The skein
will thus be of a length according to the amount of cord wound on and according to
the length of said cord and to the proportions of the gear e¹ el el.
To set in action the machine so stopped the cord is again wound on the drum and
the parts returned to their original position.
The slivers from each, set of bobbins H after passing through the automatic stop
mechanism as before described are collected by an eyelet T¹ whence they pass over
and around the roller L so as to pass between said roller and the roller R to the
eyelet D as before mentioned. P P are fast and loose pulleys for driving the main
shaft.
By changing the roller T for others of different diameters, skeins of different
diameters can be obtained without altering the annulus or rail A guiding the
carriage C

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. The combination in a single machine of mechanism for doubling twisting and
skeining simultaneously.
2. The machine, substantially as herein described for doubling, twisting and
skeining.
3. The combination with a doubling machine of any construction, of spinning and
skeining mechanism substantially as set forth, and devices for stopping the machine
substantially as and for the purpose set forth.
