Improvements in the Manufacture of Yarns Made from Wool or
from Wool and other Fibre or Fibres Combined, and in
· Apparatus employed therefor.
-
We JOHN LEWIS BYROM and BENJAMIN FRANKLIN BYROM both of Slackcote
Mills Delph near Oldham in the County of York, Woollen Manufacturers, and
Cotton Spinners, do hereby declare the nature of this invention to be ás
follows:-
This invention relates principally to such twisted yarns as are usually made in a
mule by doubling two or more twisted ends or threads together, such ends or
threads being either entirely formed of wool, or partly of wool and partly of other
fibre or fibres, or one end or threads being of wool or partly of wool and another of
cotton or other fibre or mixture of fibres.
Hitherto such yarns have been made in a woollen mule by first spinning the
roving on a mule spindle as it comes directly from the condenser bobbins, each end
thus requiring separate spinning, and afterwards twisting or doubling these spun
threads together in a similar machine, and thus the yarn requires three or more
processes before completion (according to the number of the ends or threads
twisted together).
According to this invention the yarn of two or more ends can be made in one
process, and the invention consists in producing such yarn by drawing or drafting
the woollen or partly woollen rovings between two or more pairs of draw rollers as
they pass to the mule spindles to be twisted together.
When it is desired to twist a woollen or partly woollen end, or ends, together
with an end or thread, or more than one end or thread of cotton or other fibre, the
latter may be either in the form of a roving or a twisted thread.
If the cotton or other fibres is in the form of a roving it is drawn or drafted like
the woollen or partly woollen end. If such cotton or other end is twisted it is
passed over the first pair or pairs of draw-rollers and delivered with the woollen or
partly woollen end between the last pair of rollers before passing to the mule
spindle.
In this case the twisted end or thread is so arranged as to pass from the creel
under the condenser bobbin in order to avoid friction against the roving on the
said condenser bobbin. For this purpose the drums upon which the condenser
bobbins rest are made with a number of grooves through which the threads from
the creel can pass freely, and thus these threads need not touch the roving on the
condenser bobbin.
By this process the yarn is spun and twisted simultaneously, thereby saviog
much time and labor in the manufacture.
The ends twisted together may be alike or different in color.
It will be found that by the above process a finer yarn can be spun from the
same material, and that such yarn is softer and fuller than an ordinary doubled
yarn.
If desired a yarn from a single woollen or partly woollen roving may be drawn
and spun simultaneously by a similar method.
Dated this 19th day of October 1894.

Improvements. in the Manufacture of Yarns Made from Wool or
from Wool and other Fibre or Fibres Combined, and in
Apparatus employed therefor.
We JOHN LEWIS BYROM and BENJAMIN FRANKLIN BYROM, both of Slackcote
Mills, Delph near Oldham, in the County of York, Woollen Manufacturers and
Cotton Spinners, 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 relates principally to such twisted yarns as are usually made in a
mule by doubling two or more twisted ends or threads together such ends or
threads being either entirely formed of wool or partly of wool and partly of other
fibre or fibres, or one end or thread being of wool or partly of wool and another of
cotton or other fibre or mixture of fibres.
Hitherto such yarns have been made in a woollen mule by first spinuing each
roving on a mule spindle as it comes directly from the condenser bobbins, each end
thus requiring separate spinning and afterwards twisting or doubling these spun
thrends together in a similar machine, and thus the yarn requires three or more
processes before completion (according to the number of the ends or threads
twisted together).
Our invention will be readily understood from the following description on
reference to the annexed sheet of drawings of which
Fig. 1 is a sectional view or diagram illustrative of our improved apparatus.
Figs. 2 and 3 are enlarged views in section of our improved drum for supporting
the condenser bobbins when a twisted end is to be combined with an untwisted end.
On Fig. 1, a, a, are the condenser bobbins resting on the drums bb respectively,
c is one of the ordinary mule spindles on the carriage c¹; as seen however on
Fig. 1, a and are not in use as will be hereinafter described.
According to this invention the yarn of two or more ends can be made in one
process, and the invention consists in producing such yarn by drawing or drafting
the woollen or partly woollen rovings between two or more pairs of draw rollers as
they pass to the mule spindles to be twisted together. Or, when it is desired to
twist a woollen or partly woollen end (or ends) together with an end or thread (or
more than one end or thread) of cotton or other fibre, the latter may be either in
the form of a roving or a twisted thread.
are
In the case of spinning two untwisted woollen or partly woollen ends together
the ends from the condenser bobbins a a' are passed together through two (or
more) pairs or sets of drawing rollers d d' by which they are drawn or drafted
before being twisted by the spindle c into yarn, and the parts marked ¹, x², ³,
dispensed with or left out of use. The first rollers d are, or may be, similar to the
ordinary delivery rollers of a woollen mule, but although driven at the usual speed
their motion is of course not arrested as usual, as the drawing or drafting is effected
between them and the rollers d' and not by the spindle c as usual.
In the case of spinning an untwisted woollen or partly woollen end or ends with
an end of cotton or other fibre, when the latter is in the form of a roving it is
taken from a bobbin not shewn en Fig. 1 and drawn or drafted by the rollers d d²,
simultaneously with the end which is taken from the condenser bobbin a. if
however such cotton or other end (or one of the woollen or partly woollen ends
where two or more such ends are to be spun together) is twisted already, it is
passed over the first pair or set of draw rollers d and delivered by the rollers d'
with the untwisted woollen or partly woollen end as seen at Fig. 1, which shews a
twisted end from the bobbin on the creel being spun together with an
untwisted end at from the bobbin'a.

page_text: The twisted end may be taken from a cop as seen dotted at on Fig. 1. In
either case last above described the condenser bobbin a¹ would be removed, and
the twisted end would be so guided by a rail or rail and rod or wire or
otherwise, that it will pass from the bobbin or under the condenser bobbin a
in order to avoid friction against the roving wound on the condenser bobbin.
For this purpose the drum bupon which the condenser bobbin a rests is made
with a number of grooves 6+, (as seen detached on Figs. 2 and 3) through which
the ends from the creel or can pass freely without touching the roving on the
condenser bobbin, as shewn on Fig. 1.
It will of course be understood that in the case of untwisted woollen or partly
woollen ends being spun together the drum b may be an ordinary plain drum
similar to 6' (or a grooved drum covered with cloth).
By this process the yarn is spun and twisted simultaneously thereby saving much
time and labor in the manufacture.
The ends twisted together may be alike or different in color.
It will be found that by the above process a finer yarn can be spun from the
sume material and that such yarn is softer and fuller than an ordinary doubled
yarn.
If desired a yarn from a single woollen or partly woollen roving may be drawn
and spun by a similar method, that is to say by the use of drawing rollers such
as d d between the condenser bobbin as seen at a and the drum and the
spindle c.
We would remark in conclusion that although we have only illustrated our
method and apparatus as applied principally to the spinning of two ends together
it will be evident without further illustration that more than two ends can be spun
together according to our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Doubling or twisting together two or more untwisted ends of woollen or
partly woollen fibre in one process by drawing or drafting the untwisted rovings
by means of draw rollers as they pass from the condenser bobbin to be spun by the
mule spindle substantially as herein before described.
2. Doubling or twisting an end or ends of untwisted woollen or partly woollen
fibre together with an end or ends of twisted fibre by drawing or drafting the
untwisted end or ends and delivering it or them with the twisted end or ends to be
twisted or doubled into yarn by the mule spindle substantially as hereinbefore
described.
3. As an improved manufacture yarn produced by the method or methods
described in the foregoing claims.
4. In a woollen mule the combination with the drum or drums for rotating the
condenser bobbin or bobbins of a set of draw rollers arranged between the said
drum or drums and the mule spindles, the whole operating substantially as and for
the purposes herein before described and illustrated by the drawings annexed.
5. In a woollen mule the combination with the spindles and draw rollers, of a
grooved drum or drums for supporting and rotating the condenser bobbin or
bobbins and for allowing a twisted end or ends to pass beneath the condenser
bobbin or bobbins without friction against the roving wound thereon, substantially
as hereinbefore described and illustrated by the annexed drawings.
