WILLIAM FRANK TIMPERLEY, Spinner and Merchant, of Dewsbury, in the County
of York. "IMPROVEMENTS IN DOUBLING, TWISTING, WINDING, AND REELING, AND
IN APPARATUS CONNECTED THEREWITH."
"
This Invention relates to improved means of stopping the delivery and twist
simultaneously on the breakage of one or more threads or strands during the process
of doubling, twisting, winding, or reeling any number of threads or strands on to
bobbins, reels, or spools, producing perfect threads or cords of any number of threads
or ends. For this purpose on the bottom or at the back of the frame I place
bobbins or cops, whose threads, strands, or ends pass over a knee board, which may
be fitted with a brush to produce tension; these threads, strands, or ends pass also
over a rod or guide, and through twizzles or eyelets formed on the tops of balanced
wires or levers. The levers work on fulcrums in swinging frames, and the bottom
ends of the balanced wires or levers are formed with hooks or catches, which gear
on the breakage of a thread or threads, strands, or ends into a tooth or the teeth of
a revolving pinion or reel stopping it. The tension of the threads, strands, or ends
passing through the twizzles or eyelets holds the balanced wires or levers up, but
should one or more ends break, the balanced wires or levers fall, and the hooked
catch or catches gear in a tooth or the teeth of the revolving pinion or reel, stopping
it and forcing upwards the swinging bracket, which actuates a cranked lever, and
liberates a straight lever fitted to a connecting rod, which actuates and throws out
of gear a friction pulley, drum, or bevil mitre wheel, stopping the spindle. This
motion simultaneously stops the delivery and twist on the breakage of one or more
threads for doubling.
For stopping the delivery in winding I employ a similar apparatus to that
herein-before described, the straight lever of which actuates a sliding catch lever,
which gears on the breakage of a thread, strand, or end into a ratchet toothed
pinion or ratchet wheel, stopping it. The ratchet pinion or ratchet wheel is con-
nected to a drum or take-up roller, over which the yarn or threads is wound once
or more times. The yarn or threads are guided to the drawing or taking up roller
by small rollers or guides, and the take-up motion is actuated by a drum wheel,
band, tape, or strap. The spindle is driven by a bevil, friction, or mitre wheel

fitted on a rail and traverse rail actuated by a cam.
I also employ an apparatus for redoubling or retwisting two or more doubled
yarns or threads in the process of hanking, uniting, or reeling, either singly or
jointly with the stop twisting or winding motion herein-before described, but
instead of employing a fixed cop or bobbin board I employ a revolving disk plate
or spindle driven by strap, band, friction, or wheel gear.
The stop motion for all yarn winding on bobbin, creel, or reel is constructed with
other weighted balanced wires or levers having twizzles or eyelets through which
the yarn passes in. winding, holding them up. On the breakage of one or more
ends the balanced wire or wires drop on to a-lever actuating a small arm or lever,
which liberates a spring toothed catch, stopping all ends in the broken yarn, passing
on to the reel or bobbins until again joined, which produces uniformity of the number
of strands in any given yarn.
