I, WILLIAM TERRELL GARNETT, of Barkerend Mills, Bradford in the County
of York Spinner, do hereby declare the nature of my invention to be as
follows:-
The object of my invention is to drive the spindles of spinning and twisting
frames by arranging the wharls on the spindles in such a manner, that the wharl
on any spindle may be dinengaged so that the spindle will remain at rest, for
the piecing up of the yarn or for other purposes; but the disengaged wharl will
continue to revolve, and thus not interfere with the tension on the driving band
or tape, or the speed of the other spindles driven by the same band or tape.
I accomplish my object by placing the wharls on the spindles so that when they
are not in gear with my apparatus, they run loose on the spindles.
Upon each spindle immediately below the loose wharl, I secure a tube having a
collar at the bottom end, and enclose the tube with a sleeve in which is placed a
spiral spring that is compressed between the before mentioned collar and the
interior of the sleeve.
When the sleeve is moved from the wharl, and so long as it is held by a spring
catch, the sleeve and wharl are disengaged; the wharl remaining at the same
elevation and continuing to revolve, the tension on the driving band or tape
remains the same, and therefore does not interfere with the speed of the other
spindles driven by the same band or tape. On liberating the spring catch, the
sleeve and wharl gear with each other, thereby causing the spindle to revolve.

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:-
The object of my invention is to drive the spindles of spinning and twisting
frames by arranging the wharls on the spindles in such a manner, that the wharl
on any spindle may be disengaged so that the spindle will remain at rest for the
piecing up of the yarn or for other purposes, but the disengaged wharl will
continue to revolve and thus not interfere with the tension of the driving band or
tape or the speed of the other spindles driven by the same band or tape, thereby
preventing the production of uneven twisted yarn.
:
I accomplish my object by placing the wharls on the spindles so that when they
are not in gear with my apparatus they run loose thereon. Below the wharl I fix
a tube around which slides a sleeve, the latter being attached to the spindle by
means of a feather key let into it. The sleeve is caused to engage with the loose
wharl by means of a spiral spring compressed between the fixed tube and the
interior of the sleeve. When the sleeve is pressed down and disengaged from the
loose wharl, it is held in that position by means of a spring catch, the wharl
continuing to revolve without turning the spindle, thus the tension of the driving
band or tape remains the same, and the stopping of one spindle does not interfere
with the speed of the other wharl and spindle driven by the same band or tape.
In order to explain more fully my invention, I append lierewith a sheet of
drawings in which Fig. 1, represents a section of a portion of a spinning franie
fitted with my improvements: Fig. 2 a front view of the same: Figs. 3 and 4 an
enlarged elevation and section respectively of a detached spindle, and Fig. 5 a
plan, with the loose wharl removed.
The letter A indicates the spindle: B the loose wharl resting on a shoulder of
the spindle A and secured above by a collar A¹. C is a tube pinned securely to
the spindle A around which slides the sleeve D engaging with the catches E on the
underside of the loose wharl B. Between the tube C and the interior of the
sleeve D, and coiled around the spindle; is, the compressed spring F which keeps
the sleeve D in gear with the loose wharl B, the band or tape driving the wharl
and sleeve, the latter being attached to the spindle A by means of a feather key G,
shewn in Fig. 5, which is fixed into the spindle and projects into the sleeve D.
When it is necessary to stop a spindle for the purpose of piecing up, the sleeve D
is disengaged from the loose wharl B by simply sliding it down the spindle clear of
the wharl catches E in which position it is held by the spring catch H until the
spindle is required to revolve again, when the spring H is pulled back thereby
liberating the sleeve D: the rod J acting as a guard to prevent it being pulled
back too far, and the sleeve D being free, is lifted up by the compressed spring F
and again gears with the loose revolving wharl B, thus by this arrangement of

page_text: stopping the spindles, the attendant having both hands at liberty, is enabled to
piece up the ends much quicker, with less waste, and much finer and better knots
than when stopped in the ordinary manner;
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
A compressed spiral spring F around the spindle A enclosed by a sliding
sleeve D, combined with the revolving wharl B substantially in the manner and
for the purpose as hereinbefore described and illustrated by the accompanying
drawings,
