Improvements in the Method of Driving the Tubes on Spinning
and Twisting Frames.
We, JOHN WILLIAM ALLAN BLACK, and HODGSON EADE, both of Folly Hall Mills,
Wibsey, near Bradford in the County of York, Worsted Spinners, do hereby declare
the nature of this invention to be as follows:-
This invention relates to certain improvements in the method of driving the wharls
and tubes on the dead spindles of spinning and twisting frames, and has for its object
the driving of the same with a minimum variation in the tension on the bands between
the top and bottom of the lifter rail traverse, and in such a manner, that the bands are.
kept clear of the wharl flanges in all portions of the traverse, and to drive them at a
more uniform speed with less wear and tear than when the ordinary method of tapes
or bands are used for the purpose.
When tapes or bands are employed, they pass around four wharls, two being on
each side of the frame, and over a weighted tension pulley near the driving cylinder,
the wharls being provided with flanges at both ends for keeping the tapes or bands
thereon when approaching the ends of the lifter traverse which then come in contact
with the tapes causing the edges of the latter to expand and travel towards the
circumference of the flanges, thereby stretching the tapes at the edges to such an
extent, that the sewing or joining soon breaks thereby stopping four tubes until
repaired.
We accomplish our object by driving with a round band one wharl and tube on
each side of the frame, the band passing around half the circumference of each wharl,
by which we obtain the necessary bite or frictional contact with the wharl, which we
form with a groove somewhat V shape, and obtain the requisite tension by passing the
band around a V grooved tension pulley, which is placed in such a position that the
bands from the cylinder and tension pulley lead to and from the wharls in such a
manner that they practically keep in the centre of the groove in each wharl, without
coming in contact with the portion of the groove near the circumference.
By means of this our improvement, less power is required and there is also less wear
and tear.

We, JOHN WILLIAM ALLAN BLACK, and HODGSON EADE, both of Folly Hall Mills,
Wibsey, near Bradford, in the County of York, Worsted 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 to certain improvements in the method of driving the wharls
and tubes on the dead spindles of spinning and twisting frames, and has for its object,
the driving of the same with a minimised variation in the tension on the bands
between the top and bottom of the lifter rail traverse, and in such a manner, that the
bands are kept clear of the wharl flanges in all positions of the traverse, and to drive
them at a more uniform speed with less wear and tear than when the ordinary method
of tapes or bands are used for the purpose.
When tapes are used in the ordinary manner they pass around four wharls, two
being on each sides of the frame, and over a weighted tension pulley near the driving
cylinder, the wharls being provided with flanges at both ends for keeping the tapes
thereon when approaching the ends of the lifter traverse, which then come in contact
with the tapes, causing the edges of the latter to expand and travel towards the
circumference of the flange, thereby stretching the tapes at the edge to such an
extent that the sewing or joining soon breaks, thereby stopping four tubes until
repaired.
We accomplish our object by driving two tubes and wharls with one band and
acquire the required tension on the same by a V grooved tension pulley mounted in
such a position that the respective bands lead to and from the wharls in such a manner
that they practically keep in the centre of the groove in each wharl thereby reducing
the wear and tear of the band, and run the tubes at a more uniform speed throughout
the entire length of the traverse.
In order that our invention may be better understood we will describe the same
more in detail by making reference to the accompanying sheet of drawings in which
Fig. 1 represents a section through such portions of a spinning or twisting frame as
are necessary to illustrate our invention. Fig. 2 is a plan of the same partly in section,
and Fig. 3 a detail of the grooved tension pulley and bracket.
To the spindle rails A we secure in the ordinary manner a series of dead or
non-rotating spindles B, each spindle being provided with a tube of the
ordinary description, and to the bottom of the same we secure a grooved wharl D, the
groove being formed V shaped to receive the driving band E. Round the ordinary
driving cylinder C, we pass the driving band E, which runs in the direction of the
arrows around half the circumference of each wharl D, thus obtaining the

page_text: necessary amount of frictional contact, and finally round the grooved tension
pulley H.
We mount the V grooved tension pullies H, on supports J, each of which is
carried by the bar K, running the whole length of the spinning or twisting frame;
the supports J, being each provided with a projecting arm J', upon which is placed a
weight L, by which each respective pulley is forced towards the spindles in the
direction of the curved arrow 2, thus giving the requisite tension to the driving
band E.
By mounting the tension pullies in the manner described and illustrated, the driving
bands E lead to and from the wharls D in such a manner, that they practically keep
in the centre of the V shaped groove of the wharls throughout the entire traverse of
the lifter rail M, without coming in contact with the portion of the groove near
the circumference; thus running the tubes at a more uniform speed, minimising the
variation in the tension of the driving bands E, and reducing the wear and
tear of the driving bands, consequently requiring less power to drive the
machine.
By forming the supports J, with a binding projecting arm J2 in the position shewn,
the same allows the use of a great deviation in the length of the driving bands E, the
supports J being hinged on the bar K; when a short band E is put on to drive the
wharls and tubes, the respective pulley H is drawn towards the cylinder C, therefore
bringing the top edge of the projecting arm J' towards the driving band on the top
side of the pulley, and as the band expands, the pulley H moves from the cylinder C,
thereby bringing the lower edge of the said arm towards the band running from the
underside of the said pulley.
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, we declare that what we claim is :-
Tension pullies and wharls having ✓ grooves therein, combined with driving
bands E conducted to and from the driving cylinder C, substantially in the manner
shewn and described.
Tension pulley supports J, having a binding projecting arm J' formed thereon,
substantially in the position shewn and described.
