page_text: LETTERS PATENT to Edward Whalley and James Horrocks, of Manchester,
in the County of Lancaster, for the Invention of "IMPROVEMENTS IN MACHINES
USED FOR WINDING, DOUBLING, AND TWISTING TEXTILE OR FIBROUS YARNS OR
THREADS ON TO BOBBINS, SPOOLS, COPS, OR REELS."
Sealed the 28th August 1877, and dated the-9th May 1877.
COMPLETE SPECIFICATION filed by the said Edward Whalley and James
Horrocks at the Office of the Commissioners of Patents on the 9th May 1877.,
EDWARD WHALLEY and JAMES HORROCKS, of Manchester, in the County of
Lancaster. "IMPROVEMENTS IN MACHINES USED FOR WINDING, DOUBLING, AND
TWISTING TEXTILE OR FIBROUS YARNS OR THREADS ON TO BOBBINS, SPOOLS, COPS,
OR REELS."
This Invention has for its object the winding, doubling, and twisting together of
two or more yarns or threads on to bobbins, spools, or cops, in one machine instead
of employing two separate machines as heretofore, and in improved arrangements
and contrivances for stopping any of the spindles holding the bobbins, spools, or cops,
in case an end breaks, without interfering with the working of the remainder of the
machine.
The threads or yarns to be twisted and wound are drawn from cops, bobbins, or
spools, and pass through eyelets fixed on stop levers, having their bottom ends
formed as hooks or catches, and when there is a breakage or absence of thread or
yarn, one of the hooks or catches which has been held up by the tension of the
thread is caught by a revolving ratchet wheel, fixed on a shaft extending the length
of the machine, which hook slightly depresses a frame carrying the said stop levers,
which causes an, elbow-shaped lever placed on a stud on a bracket. to release a catch

page_text: and let fall a weighted lever, which depresses another lever, having its fulcrum in a
bracket fixed on a rail extending the length of the machine, and causes the collar
on the spindle to be raised from the driving discs, and thereby stops its revolutions,
and at the same time by means of a connecting rod fixed on the elbow lever pushes
a bar against the hooked catches, and prevents them from coming in contact with
the revolving ratchets on the shaft.
This Invention will be clearly understood by the following particular description
thereof, reference being had to the figure and letters on the accompanying Drawing
(which is an end view) of the machine with the end frame removed for the purpose
of shewing the parts.
On the side of the machine is placed a wooden trough a having in it fixed rods,
on which are placed the cops, spools, or bobbins b, containing the threads or yarns to
be twisted and wound, which are drawn from the said cops b, and pass through
eyelets c fixed on the wooden rail d, and over the rod e, which extends from one
end of the machine to the other, then through the eyelets f fixed on the stop
levers g, then two or three times round the draw rollers h, i, and over the rod j to
the flyer k where they are twisted and wound. The stop levers g which work loose
on a rod in the frame k¹ have their bottom ends formed as hooks or catches which
are held up and balanced by the threads or yarns when entire, but when a thread
breaks one of the hooked catches is caught by one of the revolving ratchet wheels 7,
fixed on the shaft m, extending the length of the machine, which brings into action
the swing frame k¹, carrying the hooked catches g, which frame slightly raises the
elbow-shaped lever n, which is weighted at the front end, and thereby releases the
catch lever o, having attached to it the connecting rod p, jointed to the lever q, on
which is hung the weight r, which rod is pulled down by the weight r, and in
falling acts upon one end of the lever q, working on a fulcrum z, in the bracket
fixed on the rail 8, and thereby raises the collar t from the driving disc and stops
the spindle. On the catch lever o is a small rod w working in a slot in the catch
lever OC, and as the catch lever o falls it places the catch on the lever on the ratchet
wheel a¹ on the draw rollers i, and stops them, and so prevents any unnecessary yarn
or thread being drawn from the spool or bobbins b.
When the thread or yarn is pieced and it is desired to set again to work the
spindle that has been stopped through its absence of yarn or thread, the handle y on
the catch lever o is raised, thereby putting all the parts into their original working
positions.
.
The lifting rail, which raises and lowers the bobbin, is moved up and down by the
ordinary heart motion.
Having now described the nature and particulars of our said Invention, wo desire
it to be understood that we do not confine ourselves to the precise details herein
set forth, as such may be varied or modified without departing from the principle
of our Invention; as for instance, we have only herein described and shewn this
machine as for winding, doubling, and twisting yarns or threads on to bobbins,
spools, or cops; still it is evident that we can wind, double, and twist yarns and
threads on to reels or hanks; also that the stop motion may be altered, so that the
rotary ratchet wheel instead of revolving may have a sliding motion given to it,
either vertically or horizontally; also that the draw rollers may be stopped when a
thread breaks by a break or toothed ratchet or wedge instead of the mode described,
and that they may also be driven direct by bevil wheels or friction instead of
banding, if placed in a vertical position; as also that instead of the spindles being
driven by friction discs, as described and shewn, they may be driven direct by
gearing or by a band or strap from a pulley or tin drum with fast and loose pulleys,
or fast and loose friction pulleys or clutch boxes on the spindles; and for very fine
counts of yarns or threads this latter mode might be even more advantageously used
than the plan shewn and described; but what we desire to claim as our Invention is,
the winding, doubling, and twisting together of two or more yarns or threads on to
bobbins, spools, cops, or reels, in one machine instead of separately as heretofore,

page_text: substantially as such machine is herein described and illustrated in the accompany-
ing Sheet of Drawings.
In witness whereof, we, the said Edward Whalley and James Horrocks, have
hereunto set our hands and seals, this Twenty-ninth day of March, in
the year of our Lord One thousand eight hundred and seventy-seven.
