PROVISIONAL SPECIFICATION left by Charles Parker at the Office of
the Commissioners of Patents, with his Petition, on the 31st March
1856.
I, CHARLES PARKER, of Dundee, in the County of Forfar, North Britain,
Manufacturer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR WINDING YARNS OR THREADS," to
be as follows, that is to say :-
This Invention relates to the arrangement, construction, and working of
machinery or apparatus to be used for winding various classes of yarns or
threads, the essential object of the improvements being the obtainment of an
uniform or equable take up of the yarn or thread as it is wound into the
required form.
The said Invention is applicable to machines having either horizontal or.
vertical spindles, but in vertical spindle machines it may be conveniently and
effectually carried out in practice in this manner :-Near the bottom of the
framing there is fixed up a longitudinal rail or fixed supporting bar, fitted
at the proper intervals asunder with wide vertical bearings to receive the
tubular sockets of the pinions on the winding spindles. These pinions
may either be toothed skew bevils or frictional cones, and the whole set
for a line of spindles are actuated by corresponding skew bevils or cones
set upon a horizontal longitudinal shaft above, such shaft being driven by

page_text: gearing from the first motion of the machine in the usual manner, except
that the wheel train comprehends a pair of geared eccentric wheels. These
eccentric wheels or their equivalents are so arranged as to give an accelerated
speed to the winding spindles when the yarn is being wound upon the
small end of the cop or built up mass, and a reduced rate when winding upon
the larger end. In this way a regular and uniform take up of the yarn is
effected. Where frictional driving cones are used, a spring or elastic con-
nection is formed between a collar on the shaft and the boss of the driving
cone, in each case to keep the surfaces in secure frictional driving gear.
The tubular socket of the spindle pinion in each case is quite loose and free
in its bearing in the rail, and the spindle has its lower end passed loosely
through it, the footstep of the spindle beneath being supported by a weight
suspended over a pulley, or the ordinary lever or spring rest may be employed
for the same purpose. The lower part of the spindle passing through the
tubular socket of the pinion is fitted with a short projecting key or feather
fitting a corresponding longitudinal groove in the bore of the socket. At
starting, when the cop is just commencing to be built upon the upper end
of the winding spindle, the latter is of course in its highest vertical position,
and the feather in the spindle is in gear with the internal groove in the socket.
In this condition of the parts the winding goes on, as the connection
between the driving gear and the spindle is unbroken and complete. As
the cop is being built, the overhead cone in which it is formed causes the
spindle to descend slowly as each layer of yarn is wound on, until at last the
lower end of the spindle is pushed down so low that the spindle feather clears
the internal groove in the socket, and the spindle then ceases to revolve,
whilst the socket and its pinion continue to work. When the cops are doffed
the reaction of the weight or the spring upon the spindle footstep brings the
spindle back into gear again with its socket, owing to the absence of the cop,
and the winding then again proceeds as before.
It is an important feature of this Invention that the driving wheels or cones
forming the immediate gearing of the spindle remain continually in gearing
contact with each other without the necessity of any shifting or traversing
motion back and forward for building the cone, either as regards the wheels or
the spindles. The traversing of the yarn for effecting the proper build of the
cop is effected by an eccentric movement in the usual manner.
