Improvements in the Method of and Machines for Spinning and
Doubling Yarn.
I, WILLIAM EDWIN HEYS of 70 Market Street Manchester in the County of
Lancaster, Fellow of the Chartered Institute of Patent Agents, 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 :-
When two persons stand face to face and rotate in the same direction the opposite
ends of a length of yarn that is to say, if each rotates the yarn to the right or to
the left, a double amount of twist will be produced, or twice as many turns in a
given length will result as would be produced if one of the persons only caused the
yarn to rotate upon itself.
In existing spinning and doubling machines, the amount of twist produced,
corresponds with that which would be produced by a single person twisting one end
of the yarn and the object of this invention is to produce twice the number of turns
such as would be produced by the two persons twisting opposite ends of the yarn as
before described.
For the purpose of this invention the spindle or bobbin containing the supply of
yarn or similar material to be spun or doubled is rotated and the yarn is delivered
therefrom in such a manner that twist is produced. The amount of twist so
produced is added to the twist produced by the ordinary spindle.
It is preferred
to rotate the bobbin or spindle from which the yarn or the like is derived at the
same speed as the spindle of the machine, in which case twice as many turns will
be produced in a given length as would be produced by the action of the spindle
alone.
These improvements may be applied to all kinds of spinning and doubling
machines, and may be adopted in the working of all kinds of silk, cotton, ramie,
jute, linen, and other yarn in every case where twist has to be produced.
The accompanying drawing illustrates in what manner this invention may be
carried into practical effect. In these drawings these improvements are illustrated
as applied to a ring spinning frame, but it is to be understood that they are not
limited to this class of machine, but may be similarly applied to spinning and
doubling machines of any kind whatever.
The figure represents a cross sectional elevation through one half of the frame.
A is the tin cylinder and B'is the driving band which passes round the tin
cylinder, thence to the pulley C on the ring spindle, back to the cylinder A, thence
round the pulley D, and back to the tin cylinder. Hence the band which drives
the wharve or pulley C also drives the similar pulley D, and at the same speed.
This arrangement is however not essential since the two spindles may be separately
driven. As however it is important that both spindles should stop and run simul-
taneously, it is better to drive them by the same band. Difference of speed if
desired, may be secured by a difference in diameter in the pulleys B and D. It
will be evident that the pulleys must be rotated so that each produces twist in the
same direction, for it is obvious that if they rotate in opposition directions the twist
produced by one will be taken out by the other.
The inclined spindle upon which the pulley D is fixed, carries the bobbin H,
upon which the yarn or the like which has to be spun or doubled is wound, in one
or more ends as may be required.
The varn leaves the end of the bobbin and is conducted directly through the

page_text: thread guide G to the rollers I J, between which and the bobbin the first twist is
imparted. The second twist is produced in the usual manner between the draw
rollers J and the ring spindle, by the act of rotation of this spindle.
Between neighbouring or consecutive bobbins H, there may be arranged any
suitable anti-ballooning devices or means for preventing the entanglement of their
respective threads. Any known or convenient system of brakes or stop motions
may be employed for arresting the motion of any pair of spindles C D without
stopping the others.
The spindles shewn in the drawings are or resemble those used at present in the
ring frame, and in the self-acting mule respectively, the first being vertical and
surrounded by its ring K, and the second inclined or arranged to deliver its yarn
about parallel with its axis. Any other construction of spindles and any
arrangement which will produce a similar result may however be employed
at will.
By the adoption of these improvements a double production is obtained as
compared with existing machines and an important economy in driving power, of
space, of machinery, and of operation is secured. The cumbrous bobbin carriers
are dispensed with, and consequently the work of the operative is rendered much
more convenient and comfortable.
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 hereinbefore described method of spinning and doubling, which consists
in producing one half or a part of the total twist by the rotation of the supply
bobbins or spindles, and the remainder by the ordinary bobbins or spindles, sub-
stantially as set forth.
2. In spinning and doubling machines, the combination and arrangement with
the ordinary spindles or bobbins by the rotation of which the twist is at present
produced, of drawing rollers, and rotating bobbins or spindles on which the supply
of yarn to be spun or doubled is carried, substantially as herein before described and
as illustrated by the accompanying drawing.
3. In spinning and doubling machines, rotating spindles or bobbins on which the
supply of yarn is carried constructed arranged and rotated substantially as and for
the purpose hereinbefore described and as illustrated by the accompanying
drawings.
