Improvements in Mules and Twiners.
I, ARTHUR PLATT-HIGGINS, of 15 Lansdowne Road, Didsbury, in the County
of Lancaster, Cotton Spinner, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the spindles employed in mules and twiners and my
chief objects are
to improve the operation of twisting by overcoming the
vibration of the yarn during twisting and to prevent the formation of snicks
and snarls.
According to my invention I make the point of the spindle cone shaped so
as to keep the thread to the centre of the spindle during the process of twisting
instead of its slipping or flirting from the shoulder of the spindle which frequently
occurs with spindles of the shape now universally employed. This conical form
does not in any way interfere with the diameter of that portion of the spindle
upon which the cop is built.
·
I am aware that spindles have been made thinner in the blades in various
ways so much so as to weaken the spindles and to make the size of hole in the
finished cops undesirably small but I claim as a distinct feature of novelty the
principle of employing a spindle with a comparatively thick blade upon which
the cop is built and with a cone shaped end round which the coils of yarn
wrap and remain during the twisting and whereby I am enabled to bring the
thread approximately to the centre of the spindle for and during the process of
twisting.
By thus spinning from the point I find I can vary the bevel of the spindle,
that is the inclination of the spindle towards the roller beam, with great freedom
and consequently put the spindle much more upright which not only obviates
the chance of coils of yarn slipping off and making snicks but also enables me
if desired to get a longer stretch of yarn each draw of the mule without
occupying more floor space.

Improvements in Mules and Twiners.
I, ARTHUR PLATT-HIGGINS, of 15 Lansdowne Road, Didsbury, in the County
of Lancaster, Cotton Spinner, 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 :-
My invention relates to the spindles employed in mules and twiners and my
chief objects are to improve the operations of twisting by overcoming the
vibration of the yarn during twisting and to prevent the formation of snicks
and snarls.

page_text: According to my invention I make the point of the spindle cone shaped and
preferably slightly hollowed so as to keep the thread as far as practicable to
the centre of the spindle during the process of twisting instead of its slipping
or flirting from the shoulder of the spindle which frequently occurs with
spindles of the shape now universally employed. This conical form does not in
any way interfere with the diameter of that portion of the spindle upon which
the cop is built.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being
had to the figures and letters marked thereon.
Figure 1 is an elevation of one form of my improved spindle and Fig. 14 is
an enlarged view of the upper portion of the same.
Figures 2 and 24 are similar views to Figs. 1 and 1ª respectively of an'
alternative form of my improved spindle.
Figure 3 is an elevation of the ordinary form of spindle in general use prior
to my present invention.
In Figures 1, 1^, the blade of the spindle which is of the usual dimensions
is marked and the taper or cone shaped end is marked c, the point of
tapering beginning just above the end of the cop d which is indicated by
dotted lines.
The spindle illustrated by Figs. 1 and 1 is adapted to work in the mule
carriage and at the ordinary bevel or inclination the pointed end of the spindle
being just sufficiently rounded to protect the, operatives hands from injury when
piecing etc., while the reduced taper portion c of the spindle is sufficient to
prevent the yarn slipping or flirting from the reduced shoulder of the spindle
during the process of twisting and thus obviates a difficulty experienced with
the ordinary form of spindle shown in Fig. 3 and produces a yaru clear or
comparatively clear from snicks and snarls.
The spindle shown in Figs. 2 and 2 has a taper point e which allows the
spindle to be set upright in which position the yarn is brought to the centre
of the spindle and by this means the operation of spinning is as perfect as
possible but there is the objection of danger to the hands of the operatives
through the sharpness of the spindle point.
By thus spinning from the point I find I can vary the bevel of the spindle,
that is the inclination of the spindle towards the roller beam, with great freedom
and consequently put the spindle much more upright which not only obviates
the chance of coils of yarn slipping off and making snicks but also enables me
if desired to get a longer stretch of yarn each draw of the mule without
occupying more floor space.
I am aware that spindles have been made thinner in the blades in various
ways so much so as to weaken the spindles and to make the size of hole in the
finished cops undesirably small but I claim as a distinct feature of novelty the
principle of employing a spindle with a comparatively thick blade upon which
the cop is built and with a cone shaped end round which the coils of yarn
wrap and remain during the twisting and whereby I am enabled to bring the
thread approximately to the centre of the spindle for and during the process
of twisting.
Having now particularly described and ascertained the nature of my said
invention and in what manner. the same is to be performed 1 declare that what
I claim is:-
1. The herein described improvements in mules and twiners which consist
essentially in the construction use and application of spindles having a com-
paratively thick blade upon which the cop is built in combination with a cone
shaped or tapered end as illustrated by Figs. 1, 1, 2, 24 round which the coils
of yarn wrap and remain during the operation of twisting.

and 2, 2ª.
