I, WILLIAM TERRELL GARNETT, of Barkerend Mills, Bradford in the County of York,
Spinner, 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
on the tubes of cap and ring spinning and twisting frames in that class of frame in
which four wharls, two on each side of the frame, are driven by the same band
or tape and has for its object, the stopping of any wharl and bobbin in such a
manner, that when stopped, the speed of the other wharls driven by the same band
or tape is not interfered with; and to enable the attendant to retain the use of both hands
for joining broken ends without creating hard-and uneven twisted yarn, as is the case
when the wharls are stopped in the ordinary manner.
I accomplish my object in the following manner; I place on each spindle under the
wharl and resting on the lifter rail, a plate, to which is mounted vertically, a wharl
that is clear of the band or tape driving the wharl and bobbin resting thereon. In
each plate are formed two notches or recesses, one being deeper than the other, for the
reception of a spring stop bar for holding the plate in the required position; and when
the plate is moved in one direction, so that the wharl mounted vertically thereon comes
in contact with the driving band or tape, the latter is kept clear of the wharl on the
spindle, and at the same time, by the movement of the plate, the before mentioned
spring bars enters the second or deeper notch in the plate, and applies a break to the
wharl, thereby immediately stopping it until the plate is moved back to its original
position, when the band or tape is clear of the wharl on the plate and in contact with
the wharl on the spindle.

Improvements in Cap and Ring Spinning and Twisting Frames.
I, WILLIAM TERRELL GARNETT, of Barkerend Mills, Bradford, in the County of
York, Spinner, 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
on the tubes of cap and ring spinning and twisting frames, in that class of frame in
which four wharls, two on each side of the frame, are driven by the same band or tape;
and has for its object the stopping of any wharl and bobbin in such a manner, that
when stopped, the speed of the other wharls driven by the same band or tape
is not interfered with, and to enable the attendant to retain the use of both hands for
joining broken ends without creating hard and uneven twisted yarn, as is the case
when the wharls are stopped in the ordinary manner; and consists in placing on each
spindle under the tube wharl a plate, on which is mounted a loose or guiding wharl
that is clear of the band or tape when driving the wharl and tube, and on the plate
being moved in one direction, the loose or ginding wharl comes in contact with the
driving band or tape, by which it is moved clear of the tube driving wharl, and by the
movement of the said plate, a break, actuated by a spring, is allowed to press against
the wharl, thereby immediately stopping it and the tube and bobbin until the plate is
moved to its original position, when the driving band or tape is again in contact with
the driving wharl.
In describing my invention more in detail, reference is made to the accompanying
drawings, in which Fig. 1 represents a front elevation of such portions of two ordinary
spindles as are required to make clear my invention, Fig. 2, a sectional plan through
line a. b. and Fig. 3 a side view, partly in section, of the plate to which the loose
guiding wharl is mounted.
The spindles AA are mounted, and the lifter plate B operated in the ordinary
manner; upon the latter of which I place a series of plates C, through each of which
passes its respective spindle A. These plates are each provided with a recessed
circular projection C₁ extending through the lifter plate B and provided with a
bearing at the top and bottom for supporting or staying the spindle.
The cavity S around the spindle may be filled with spongy material, such as felt
cloth which absorbs sufficient lubricant, so that on traversing up and down the
spindle A along with the lifter plate B, the said spindle is continually lubricated.
On each plate C I place a washer upon which rests the bottom flange D¹ of the
wharl D, to the latter of which is attached the tube E of the ordinary construction.
When the tube E is in motion the plate C is in the position shewn at Cin
Figs. 1 and 2, the driving tape or band T passing over the circumference of the wharl
causes it and the tube to rotate, and when it is desired to stop a tube, the respective
plate C is moved by the handle to the position shewn at C3 in Figs. 1 and 2, thereby
bringing the vertical guiding wharl G in contact with the driving tape or band T. by

page_text: which it is moved clear of the wharl D somewhat as shewn in Fig. 2, thus removing
the motive power from the wharl; the tightening of the driving band or tape
consequent upon its diversion, is compensated by the ordinary tension pulley, thus
keeping the band or tape about the same tension.
In conjunction with each wharl D, is a break J for stopping the wharl and tube
suddenly when required; the break J being stayed by a suitable cover secured to the
lifter plate B, upon which the bottom portion of each break rests. Between the
breaks J, and enclosed by the said covor is a compressed spiral spring K, which forces
the breaks towards the wharls D, but are kept from coming in contact therewith by
the plates C, until one or both of the latter is or are moved to the position as shewn
at C3, when the notch H in the plate C that has been moved, is opposite the bottom
portion of the break which is curved to fit the said notch, and into which it is forced
by the spring K, thus the support is removed and the break allowed to press against
the circumference of the bottom flange D¹ of the wharl D; thereby immediately
stopping the wharl and tube until the guiding wharl G and plate Care operated to
bring the tape or band T again in contact with the wharl D and clear of the guiding
wharl G; thus by these means of stopping the wharl and tube, the operator has the
use of both hands for joining broken ends without creating hard and uneven twisted
yarn, and without altering the speed of the other tubes driven by the same band or
tape, as is the case when the wharls are stopped in the ordinary manner.
Having now particularly described and ascertained the nature of my invention, and
in what manner the same is to be performed, I declare that what I claim is :-
:-
The stopping of a wharl and tube by the removal of the driving band or tape,
substantially in the manner shewn and described.
The break J combined with the compressed spring K and plate C, substantially in
the manner and for the purpose set forth.
