PROVISIONAL SPECIFICATION.
Improvements in Cap Spinning and Twisting Machinery.
We, FRANK CLAY and JAMES CLAY HORSFALL, of Wharf Mills, Sowerby
Bridge, Yorkshire, Worsted Spinners, and JONAS BALDWIN, of No. 3, Hornby
Terrace, Fenton Road, Halifax, Yorkshire, Overlooker, do hereby declare the
nature of this invention to be as follows:-
Our improvements in cap spinning and twisting frames consist, firstly, in means
to be employed for lubricating the spindle and tube revolving thereon, and secondly,
in reducing the frictional contact on the base of the wharle so as to lessen the power
for driving same and to obtain increased speed.
In carrying out our invention we place over the spindle and resting upon the
lifting rail of the frame, a suitable form of collar preferably recessed on the under-
side for the reception of the ordinary cloth washer.
The upper side of the collar is cupped or recessed inwardly for receiving the
lubricant and on the upper side of the said collar we form two or more projections
on which the base of the wharle rests instead of resting as is now the case upon the
cloth washer or upon the lifting rail, thus with the base of the wharle only coming
into contact with the two projections the friction on the base of the wharle is
reduced to the lowest possible extent whereby power to drive same is reduced and
an increased speed obtained.

COMPLETE SPECIFICATION.
Improvements in Cap Spinning and Twisting Machinery.
We, FRANK CLAY, and JAMES CLAY HORSFALL, of Wharf Mills, Sowerby
Bridge, Yorkshire, Worsted Spinners, and JONAS BALDWIN, of No. 3, Hornby
Terrace, Fenton Road, Halifax, Yorkshire, Overlooker, 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 :--
Our improvements in cap spinning and twisting frames consist, firstly, in means
to be employed for lubricating the spindle and tube revolving thereon, and secondly,
in reducing the frictional contact on the base of the wharle so as to lessen the
power for driving same.
In carrying out our invention we place over the spindle and resting upon the
lifting rail of the frame, a suitable form of collar preferably recessed on the under-
side for the reception of the ordinary cloth washer.
The upper side of the collar is cupped or recessed inwardly for receiving
the lubricant and on the upper side of the said collar we form two or more pro-
jections on which the base of the wharle rests instead of resting as is now the case
upon the cloth washer or upon the lifting rail, thus with the base of the wharle
only coming into contact with the two projections the friction on the base of the
wharle is reduced to the lowest possible extent, whereby power to drive same is
reduced.
In order that our invention may be more fully understood reference is hereinafter
had to the accompanying drawings, wherein
Fig. 1 is elevation of a spindle and parts employed in cap spinning and twisting
frames shewing our improvements applied thereto, and

page_text: Fig. 2 is enlarged sectional elevation of part of same.
Fig. 3 is plan taken on line A, A, of Fig. 2.
Referring to the drawings a designates the spindle 6 the wharle secured to the
tube c which is placed upon said spindle and is adapted to rotate and to slide up
and down thereon; d is the bobbin or spool upon which the yarn is wound, e the cap,
and the lifting rail all said parts being arranged and operating in the ordinary
manner.
Resting upon the lifting rail for upou a cloth washer g and surrounding the
spindle a, is a collar h recessed at h' to receive the said cloth washor; the collar
is also cupped or recessed inwardly at 2 for receiving and containing lubricant.
This cup or concaved surface h³ enables the lubricant to be supplied direct from
the oil can as and when required, and whilst the machine is in operation and
prevents the waste of oil now occasioned by the present method of lubricating the
spindles and tubes. The lubricant supplied to the cup h² lubricates the spindle
and also the tube and wharle as they are carried up and down by the lifting
rail f. On the upper side of the collar h are two projections or horns k, k (or
more than two may be provided if desired) on which the base of the wharle rests,
instead of resting, as hitherto, upon the cloth washer or lifting rail, whereby
as the wharle revolves, the base thereof only comes into contact with the two
projections k, k, and the points of contact being brought to a minimum the
friction on said wharle is greatly reduced, and less power is required to drive the
same.
By these means we are enabled to lighten the tube, to lessen the tension on
the driving tape or belt, and to make it narrower to reduce the depth of the
wharle, and consequently shorten the tube and spindle, said parts also withstanding
longer wear and tear.
The aforesaid improvements are applicable to trap twisting frames and to drawing
boxes.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
Firstly. In cap spinning and twisting machinery, the combination with the
spindle a of a loose collar h placed over same and adapted to rest on the lifting
rail, said collar being provided with a dished or hollow portion h³ for receiving
lubricant to lubricate the spindle and tube substantially as herein shewn and
described.
Secondly. In cap spinning and twisting machinery, the combination with the
spindle a of a loose collar h having horns or projections kon which the base of
the wharle rests and revolves, substantially as herein shewn and for purposes
described.
Thirdly. In cap spinning and twisting machinery, the means substantially as
herein shewn and described for lubricating the spindle and tube and reducing the
frictional contact on the base of the wharle.
