I, ANDREW KING, of Avon Bank Factory, Rutherglen, in the County of Lanark,
North Britain, Manufacturer, do hereby declare the nature of this invention (a
communication from abroad by William Baird, of Almonte, Ontario, Canada,
Manufacturer,) to be as follows, that is to say :-
The said Invention has for its object to improve the construction and action of
mechanism for driving spindles used in spinning, twisting, or winding; and relates
more particularly to mechanism of the kind in which the driving is effected by a
cord or band actuated by a drum or pulley and acting on a small pulley or wharve
fixed on the spindle.
In carrying out the Invention a small pulley or wharve of vulcanised rubber or
other similar compressible or elastic material is fixed on the spindle instead of the
usual pulley of metal; and a tension pulley carried by a springing or elastic
bracket is applied to the driving cord or band. The application of the tension
pulley prevents imperfect action from arising through the slackening of the cord or
band, and renders it unnecessary to put on the cord or band with extra tightness
at first as is commonly done. The rubber pulley or wharve on the spindle avoids
slipping and friction, and with it the spindle can be driven with a comparatively
small tension of the driving cord or band, whilst the pressure on the spindle
bearings is lessened and the friction in them reduced.
Dated' this fifteenth day of October 1885.

I, ANDREW KING, of Avon Bank Factory, Rutherglen, in the County of Lanark,
North Britain, Manufacturer, do hereby declare the nature of this invention (a
communication from abroad by William Baird, of Almonte, Ontario, Canada,
Manufacturer) 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 :—
The said Invention has for its object to improve the construction and action of
mechanism for driving spindles used in spinning, twisting or winding, so as to
promote increased production of yarn or thread with the highest attainable
economy of the driving power and also to insure greater uniformity and improved
quality of the spun yarn or thread. The Invention relates more particularly to
mechanism of the kind in which the driving is effected by a cord or band actuated
by a drum or pulley and acting on a small pulley or wharve fixed on the spindle.
In carrying out the Invention a small pulley or wharve of vulcanised rubber or
other similar compressible or elastic material is fixed on the spindle instead of the
usual pulley of metal; and a tension pulley carried by a springing or elastic
bracket is applied to the driving cord or band to prevent imperfect action from
arising through the slackening of the cord or band.
And in order that the 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 to and showing the improved mechanism for driving
spindles.
.
Figures, 1, and 2, on the accompanying sheet of drawings, are, respectively a
vertical section and a plan showing the improved tension devices as applied to
parts of a spinning machine, and figure, 3, is a perspective view of the tension
device and its supporting plate drawn to a larger scale. In these drawings the
same reference numerals are used to mark the same or like parts wherever they
are repeated.
The spindle, 4, as shown in figure, 1, has the usual traversing ring rail, 5, ring, 6
traveller, 7, and guide eye, 8, through which latter the thread, 9, passes to th
bobbin or pirn, 10, placed on the spindle, 4, which is held in a step rail, 11, a
usual; but a small pulley or wharve, 12, of vulcanised rubber or other simila
compressible or elastic material is fixed on the spindle, 4, instead of the usua
pulley of metal. The spindle, 4, is driven by a cord or band, 13, actuated by
The rubb
drum, 14, and acting on the small pulley, 12, in the usual manner.
pulley, 12, on the spindle, 4, avoids slipping and friction and with it the spind
can be driven with a comparatively small tension of the driving cord or band, 1
and it will no longer be necessary to give the band, 13, a complete turn round t
driving drum, 14, as well as round the small pulley, 12, as is frequently do
where metal pulleys are used on the spindle, 4. The pressure on the spind
bearings is also lessened by using the rubber pulleys, 12, and the friction in the
reduced.

page_text: To still further prevent any imperfect action from arising through the slackening
of the cord or band, 13, a tension device is applied to the band, 13, this device
consisting of a grooved pulley, 15, journalled in the ends of elastic arms, 16, which
preferably have two or more spiral twists or bends, 17, to insure and preserve their
elasticity and which are fixed by soldering or by staples or in any other suitable
manner to a plate, 18, of metal or wood which is guided so as to slide lengthwise
on a rail, 19, fixed to the frame of the machine. The plate, 18, being provided
with a tongue or feather, 20, which slides in a groove in the rail, 19, but any
other suitable means of guiding the plate, 18, on the rail, 19, may be employed.
The plates, 18, carrying the elastic bracket or tension devices for the bands of each
pair or set of spindles, 4, is connected to a lever, 21, which is pivoted by preference
to the spindle step rail, 11. The inner end of the lever, 21, is formed with a pin
and slot connection in a bar, 22, connected to a lug, 23, on the plate, 18, but any
other suitable connection of the lever and plate may be used. The levers, 21, will
project in front of the machine so as to be conveniently operated for moving the
plates, 18, along the rail, 19, as may be required for bringing the pulley, 15, fairly
in contact with the driving sides of the bands, 13, when they may be crossed for
making reverse twist. When the pulley, 15, is in contact with the band, 13, the
pressure or tension of the elastic arms, 16, will hold it to the bands, 13, so as
to take up any slackness and insure a positive and quite regular rotative speed of
the spindles so necessary for maximum production of finished thread or yarn of
improved quality and with a minimum expenditure of power in driving the spindles.
Any tendency to subsequent slackness of the band being thus corrected it will be
unnecessary to put it on with extra tightness at first as is commonly done.
The construction and arrangement of the clastic arms, 16, may be modified to
suit the requisite degree of tension on the bands, 13, required by the nature of the
fibres being spun or the required fineness or coarseness of the yarns.
In figure, 1, the well known ring and traveller spinning arrangement is shown
but my improvements can also be applied to the ordinary flyer spinning arrangement
and also to spindles for winding only when driven by bands.
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 with the spindles, pulleys or wharves, driving drum, and
driving bands in a spinning, twisting or winding machine, of pulleys carried by
elastic or springing arms so as to apply tension to the driving bands, substantially
as hereinbefore described.
2. The combination with the spindles, the driving drum, and the spindle-driving
bands of a spinning, twisting or winding machine, of rubber or equivalent pulleys
or wharves on the spindles and pulleys carried by elastic or springing arms so as
to apply tension to the driving bands substantially as hereinbefore described.
