Improvements in Spinning and Twisting Machinery.
1, JOHN ERNEST ORR, of Cowdenhall, Neilstou, in the County of Renfrew,
North Britain, Manufacturer, do hereby declare the nature of this invention to
be as follows, that is to say :-
My said invention comprises improvements applicable to various machines for
spinning and twisting fibrous materials and yarns, but which are principally
applicable to "ring and traveller" machines. The improvements have mainly to
do with certain thread guides, but in some applications are combined with other
improvements. The thread guides referred to are those through which the
threads pass immediately prior to reaching the spindles, and which have to be
sufficiently near the upper ends of the spindles to prevent what is known as
excessive ballooning of the threads; whilst it is desirable for them to be arranged
in a manner to cause the least possible inconvenience in doffing.
In carrying ont my invention in the case, for example, of machines for wet
twisting in which the yarn passes through a trough and proceeds over a rod at the
outer edge thereof and thence down to the spindle, I have each guide, which may
consist of a bent wire, or be of any other suitable kind. fixed at the outer end of a
curved arm which extends under the trough, and is at its back end fixed to a
weight resting on a rail. The weight is formed with a notch or gab on its underside
to confine it on the rail whilst allowing it to rock thereon to a certain extent; and
the weight with the guide arm is so shaped and arranged as to have the centre of
gravity above the rail or towards the front when the guide is in its operating
position. When about to doff, the worker turns up the guide arm, and this
shifting the centre of gravity to the inner side of the supporting rail, causes it to
keep the guide arm in its raised position up against the bottom of the trough, or it
might be against any other suitable part acting as a stop. When restarting the
spinning or twisting action the worker turns down the guide arm until it reaches a
wire or other stop so placed as to determine the proper position for the thread
guide.
The improved arrangement of parts which has been described involves various
incidental advantages. There is diminished ballooning, a lighter traveller can be
used, the driving power required is diminished; less twist can be put into the yarn,
which is desirable for some purposes; and very little time is required for doffing
and restarting.
When the improved thread guides are fitted to spinning machines having
drawing rollers, these rollers may with advantage be placed more forward than
heretofore and so that the yarn may pass from the outermost pair directly
downwards through the thread guides to the spindles. And instead of the
drawing rollers being arranged as heretofore with the yarn passing through them
horizontally, they may be arranged with an inclined or even vertical disposition.

COMPLETE SPECIFICATION.
Improvements in Spinning and Twisting Machinery.
I, JOHN ERNEST ORR, of Cowdenhall, Neilston, in the County of Renfrew,
North Britain, Manufacturer, 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, that is to say :-
My said invention comprises improvements applicable to various machines for
spinning and twisting fibrous materials and yarns, but which are principally
applicable to "ring and traveller" machines. The improvements have mainly to
do with certain thread guides, but in some applications are combined with other
improvements. The thread guides referred to are those through which the threads
pass immediately prior to reaching the spindles, and which have to be sufficiently
near the upper ends of the spindles to prevent what is known as excessive
ballooning of the threads; whilst it is desirable for them to be arranged in a
manner to cause the least possible inconvenience in doffing.
In carrying out my invention in the case, for example, of machines for wet
twisting in which the yarn passes through a trough and proceeds over a rod at the
outer edge thereof and thence down to the spindle, I have each guide, which may
consist of a bent wire, or be of any other suitable kind, fixed at the outer end of a
curved arm which extends under the trough, and is at its back end fixed to a
weight rocking on a rail. The weight with the guide arm is so shaped and arranged
as to have the centre of gravity above the rail or towards the front when the guide
is in its operating position. When about to doff, the worker turns up the guide
arm, and this, shifting the centre of gravity to the inner side of the supporting rail,
causes it to keep the guide arm up against the bottom of the trough. When
restarting the spinning or twisting action, the worker turns down the guide arm
until it reaches a wire or other stop so placed as to determine the proper position
for the thread guide.
And in order that my said invention and the manner of performing the same
may be properly understood, I hereunto append a sheet of explanatory drawings, to
be hereinafter referred, and showing examples of my improvements in spinning and
twisting machinery.
Figure, 1, of the drawings is a plan of the improved apparatus, and Figure, 2, is
a sectional end elevation of the same, together with as much of the machine framing
as is considered necessary to facilitate explanation.

Figure, 3, is an elevation of the lower stop for the guide arm.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
When the apparatus is applied to machines for wet twisting, in which the
yarn passes through a trough (not shown) and proceeds around rollers, A, and over
a rod, B, at the outer edge thereof and thence down to the spindle, C, I have each
guide, D, consisting of a bent wire (or of any other suitable kind) fixed to the
outer end of a curved arm, D 1, which extends under the trough, and is at its back
end fixed by a pinching screw, D2, . into a boss, D3, formed on a weight, D4,
- resting on a horizontal rod or rail, E. The wire, of which the thread guide, D, is
made, is bent so as to permit of the length of the yarn being inserted into the bend
without being passed through it. The curved arm, D 1, is shaped so as to fit close
up to the bottom of the trough when it is turned up into the doffing position. The
weight, D4, is formed with a notch or gab, D5, on its under side to confine it on
the rail, E, whilst allowing it to rock thereon to a certain extent. The weights, D 4,
to which are fixed the several guide arms, D 1, are kept at particular positions on
the rail, E, by horse-shoe collars, E 1, which are inserted between them, and which
are fixed to the rail by pinching screws, E 2. The weight, D 4, with the guide
D1, is so shaped and arranged as to have the centre of gravity above the
arm,

page_text: rail, E, or towards the front when the guide is in its operating position. When
about to doff, the worker turns up the guide arm, D 1, and this, shifting the centre
of gravity to the inner side of the supporting rail, E, causes the weight, D 4, to
keep the guide arm in its raised position up against the bottom of the trough, or if
desired it might be against any other suitable part acting as a stop. When restarting
the spinning or twisting action the worker turns down the guide arm, D 1, until it
reaches a notched stop plate, F, fixed to the framing, G, of the machine and which
also determines the proper position for the thread guide, D.
The improved arrangement of parts, which has been described, involves various
incidental advantages. There is diminished ballooning; a lighter traveller can be
used; the driving power required is diminished; less twist can be put into the yarn,
which is desirable for some purposes; and very little time is required for doffing
and restarting. The improved mechanism may be used for either direction of
twist; the movement of the guide, D, is practically vertical; and doffing may be
effected without taking the thread out of the guide.
When the improved thread guides (D) are fitted to spinning machines having
drawing rollers, these rollers may with advantage be placed more forward than
heretofore, and so that the yarn may pass from the outermost pair directly down-
wards through the thread guides to the spindles (C). And instead of the drawing
rollers being arranged as heretofore with the yarn passing through them horizontally,
they may be arranged with an inclined or even vertical disposition.
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 :-
In spinning and twisting machinery the improved mechanism comprising a bent-
wire thread guide fixed to or formed on a rod which is fastened to a weight arranged to
rock on a rail, and having its centre of gravity above the rail the parts operating
substantially as and for the purposes hereinbefore described.
