at the Office of the Commissioners of Patents, with his Petition, on
the 16th December 1871.
I, CARL FRIEDRICH HEINRICH BOLLÉ, of the City of Manchester,
in the County of Lancaster, Engineer, do hereby declare the nature.
of the: said: Invention for "IMPROVEMENTS IN OR APPLICABLE TO MACHINERY
FOR WINDING YARN OR THREAD ON TO. BOBBINS OR SPOOLS;" to be as follows :-
My Invention relates to machinery for winding yarn or thread upon
spools or bobbins in which several spools are wound at the same time,
and where the spools when full of thread are changed for empty spools
by automatic means; as by the Invention of William Weild, described in
the Specifications of his Patents numbered 122, and dated January
22nd, 1858, and numbered 699, and dated March 16th, 1860.
.
My Invention consists in dispensing with the shaper and its connected
mechanism, described in William Weild's said Specifications, and
substituting therefor a certain wheel shaper, so arranged that it will
regulate the distribution of the thread upon the spools or bobbins, give
the movement at the required time to cut the thread against the ends of.

the spools, stop the winding mechanism when the spools are full, and
bring into operation the spool changing. mechanism, which-when-these-
operations are completed will have adjusted the traverse mechanism, and
will start the winding of the next set of spools.
The wheel shaper above referred to consists of a boss having
projecting teeth of different lengths; this boss.is. placed upon the right
and left screw shaft, and is connected to rotate therewith when at
liberty by a frictional arrangement formed by a spring or by washers
of leather, or cork and metal, tightened by a screw and lock nuts.
The teeth of this shaper wheel act upon adjustable lips secured to
two arms, each carrying part of a screw nut which correspond with the
screw threads of the screw shaft. These arms can oscillate upon the
traverse rod, and are caused to lift their screw nuts out of geer with the
screw shaft when not acted upon by the teeth of the shaper wheel by
gravity, or by springs acting upon levers, or by both combined. The
yarn or thread is cut against the ends of the spools by the action
of a cam formed upon the edge of the wheel shaper, and the winding
is stopped when a pin in the edge of the wheel shaper forces the.
end of a spring lever into a position to come in the way of one of the
adjustable lips when making its last traverse just before completing the
last layer of yarn or thread.
The movement thus imparted to this lever unlatches a bar, and
allows a spring to draw back the escape plate: lever described in
William Weild's said Specifications, and a cam on the changing cam
shaft moves 'back the-escape-plate lever in the opposite direction to
charge the spring and latch the rod, at the same time giving the lever.
the final movement to release the escape plate for the change which
starts the winding.
The cam which acts upon the escape plate lever is arranged, if required,
to turn forward partly upon the shaft without turning the shaft, this
play being allowed by a pin and slot, and this cam is turned forward-
after the change movement has commenced by a cam projection on
the belt changing shaft, which acts through levers and a rod and pawl
resting upon the edge of and acting upon a tooth in the cam on the
changing shaft, so as-to-move this cam-forward-sufficiently to clear-the-
escape plate lever, and allow its back movement to be given by the
spring at the proper time.

page_text: The traverse rod is adjusted to the proper position for commencing
the winding by a cam on the changing shaft acting through a lever
rod and link, there being a 'gap" in this cam opposite the bowl when
the winding is going on, so that the cam lever can move freely with the
traverse rod.
