PROVISIONAL SPECIFICATION.
Improvements in Cap Spinning and Twisting Machinery.
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:-
This invention relates to the spinning and twisting of yarn as effected through the
use of a loose metal tube in cap spinning and twisting, wherein the tube is attached
to the head or upper surface of the wharle, the said tube being placed and working
upon the spindle of the cap.
According to this our said invention we employ in combination with a wharle a
short length of tube, the remaining length consisting of a separate tube loose on the
spindle whereby the friction between the tube and spindle is reduced to a minimum,
and consequently the spindles are steadier through the absence or reduction of
friction. In order to prevent liability of the upper length of tube being pulled off
in the doffing we employ a circumferential groove around the spindle and in which
groove is received an elastic ring of metal which can be forced over the end of the
spindle and will contract on reaching the groove and be thereby securely held in
position.

COMPLETE SPECIFICATION.
Improvements in Cap Spinning and Twisting Machinery.
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 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 the spinning and twisting of yarn as effected through the
use of a loose metal tube in cap spinning and twisting wherein the tube is attached
to the head or upper surface of the wharle, the said tube being placed and working
upon the spindle of the cap.
According to this our said invention, we employ in combination with a wharle, a
short length of tube, the remaining length consisting of a separate tube, loose on
the spindle whereby the friction between the tube and spindle is reduced to a
minimum, and consequently the spindles are steadier through the absence or
reduction of friction.
In order to prevent liability of the upper length of tube being pulled off in the
doffing we employ a circumferential groove around the spindle and in which is
received an elastic ring of metal which can be forced over the end of the spindle and
will contract on reaching the groove and be thereby securely held in position.
Such being the nature and object of our invention the following is a complete
description of same reference being had to the accompanying drawings in
which
Fig. 1 is a sectional elevation of a spindle and appliances connected therewith as
used in cap spinning, and having our improvements applied thereto.
Fig. 2 is a view of the spindle, and bobbin, the latter being in section, in order to
clearly show the loose tube.
The remaining figures illustrate details of the said improvements.

page_text: According to this our said invention we employ in combination with the wharle 1
a short length of tube 2 cast to and forming a part of the wharle 1 as ordinary in
addition to this short tube 2 we employ a long separate tube 3 (preferably of brass)
which is loose on the spindle 4 whereby the friction between the tube 3 and spindle 4
is reduced to a minimum. The spindle 4 and cap 8 by these improvements, are less
liable to vibrate and are more steady through the absence, or reduction, of the
friction.
In order to prevent any liability of the upper or loose tube 3 being withdrawn
from the spindle 4 when "doffing" we employ in the upper part of the spindle 4 a
circumferential groove 5 around the said spindle 4, and in which groove 5 is received
an elastic ring of metal 6, or a split ring, which ring can be forced over the end of
the spindle 4 and will close, or contract on reaching the groove 5, and is thereby held
securely in position, and does not in any way impede the process of "doffing," the
bobbin 7 passing freely over the ring 6.
Having now particularly described and ascertained the nature and object of our
said invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The improvements described, wherein is comprised the wharle 1 and short tube 2
the loose tube 3 and holding ring 6 all in combination and for purpose herein set
forth, and substantially as illustrated by the drawings annexed.
2. The parts 1. 2. 3 in combination and as and for the purpose set forth and
illustrated by drawings annexed thereto.
