We, GEORGE CLEGG, JOHN THOMAS, and WILLIAM HENRY HARRISON all of
Miall Street Mills, Halifax, in the County of York, Worsted Spinners, do hereby
declare the nature of this invention to be as follows:-
Heretofore in cap spinning and twisting machinery, the bobbin has been placed on
a boss or tube, extending from the wharl, and nearly the whole length of the said
bobbin, the boss or tube revolving with the wharl on the spindle and of course carrying
with it the bobbin in which case by reason of the long boss or tube, being difficult to
fit accurately between spindle and bobbin, a great amount of vibration was caused and
consequently wear and tear to the bobbin and in some cases the vibration was so great
as to throw off the "cap."
According to this our said invention we dispense with the long tube or boss and in
lieu thereof we bush each end of the bobbin with brass, wood or other suitable
material so that the internal diameter of the bobbin is just large enough to allow the
spindle to pass through when the bobbin is passed down the spindle on to the wharl
on which there is the small holding piece as ordinary, the bobbin revolves directly on
the spindle and there is no vibration and consequently less wear and tear to the spool.
Or in lieu of bushing both ends of the bobbin we form a short boss on the wharl, and
bush one end of the bobbin so that the result is the same as above described.

Improvements in Cap Spinning and Twisting Machinery.
WC, GEORGE CLEGG, JOHN THOMAS, and WILLIAM HENRY HARRISON all of
Miall Street Mills Halifax, 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:
Heretofore in cap spinning and twisting machinery, the bobbin has been placed on
a boss or tube extending from the wharle and nearly the whole length of the said
bobbin, the boss or tube revolving with the wharle on the spindle and of course
carrying with the bobbin in which case by reason of the long boss or tube, being
difficult to fit accurately between spindle and bobbin, a great amount of vibration was
caused and consequently wear and tear to the bobbin and in some cases the vibration
was so great as to throw off the "cap."
"
In lieu of bushing both ends of the bobbin, we form a short boss on the wharle,
and bush the upper end of the bobbin.
Such being the nature and object of this our invention, the following is a complete
description of same, reference being had to the accompanying drawings:
Fig. 1. is a plan view of wharle, bobbin, and spindle.
Fig. 2. is a sectional elevation of fig. 1.
At 1. is the spindle, 2 the wharle, 3 the bobbin in which is a bush 4, the inner
diameter being equal to the diameter of the spindle 1. Forming part of or attached
to the wharle 2 is the boss or tube 5 of diameter equal to the diameter of the spindle 1,
the bush 4 and the boss or tube 5 form the bearing for the spindle 1.
We do not claim any of the parts considered separately.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
A wharle 2 having a boss or tube 5, the bush 4 and bobbin 3 all in combination as
and for purpose herein set forth, and as illustrated and described.
Dated this 21st day of June 1888.
