I, JOHN THOMAS WIBBERLEY, of Blackburn, in the County of Lan-.
caster, Machinist, do hereby declare the nature of the said. Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WINDING COTTON, SILK, OR
OTHER THREADS ON REELS OR SPOOLS," to be as follows:-
. The object of this Invention is to enable several reels or spools to have
threads wound on them in a more perfect and economical manner than
has hitherto been attained. by means of improved arrangements and
combinations of mechanism in connection with self-acting and self-
adjusting movements.
I employ right and left handed screws for moving the ordinary sliding
shaft to and fro, and traversing the thread from end to end of the reel
or spool. On the sliding shaft I place a tube working loose and
carrying at each end right and left handed nuts, and about the centre a
fixed arm extending to the top of the machine.

page_text: I also employ two stays fixed to the sliding shaft and extending
through a fixed plate on the top of the machine frame, and connected to
a slide which carries another moveable plate working in guides or
recesses, and supporting at each side a slide catch and spring. On the
fixed plate I place two cams which are alternately pressed outward by
projecting pins fixed to the arm as it traverses to and fro with the sliding
shaft, and moved inwards by levers and weights. At the sides of the
moveable plate there are slides carrying catches as aforesaid, and to cach
slide is fixed a pin which passes through a slot in the moveable plate,
and is connected to one end of a spring; the other end is attached to a
pin fixed to the moveable plate, so that when the slides and catches are
moved in one direction the springs shall give them the return move-
ment.
The catches are employed for receiving and holding the upper part of
the arm first at one side and then at the other, and thereby maintaining ]
the proper nut upon its screw, and as soon as the arm is released from
one catch it is moved by the cam and-spring to the other side, and is
received and held by the other catch.
The two slides on the moveable plate are connected to one end of the
first guide stock, and the stock itself is fitted in a cone fixed on the 2
sliding shaft, so that a radial motion may be given to the guide stock
alternately in different directions each time the guide comes in contact
with the inner ends of the spool or reel, and this radial motion of the
stock places the guide in an angular position adapted to right and left
traversing of the thread, and also gives movement to the moveable plate, 2
and thereby releases the catches alternately from the top of the arm in.
order to allow one or other of the nuts to be in action.
.)
The reels are of any desired size and shape, and one of my improve-
ments consists in certain means for enabling spindles and reels of
different sizes to be changed without altering the machine.

The spindle for holding the reels is of any desired length and is held
at one end to the main or driving shaft by means of a catch or clutch,
the end of the spindle fitting a hole in the centre of the shaft. The
other end of the spindle which is formed as a male centre is held in--
a conical hole at the end of a screw fitting a thread in a bracket or 3
shoulder, and when the screw is turned back the spindle and reels can be
removed or changed, and when turned the other way it keeps the spindle:

each having at one end a circular plate in contact with one end of the
reel, and having its inner face slightly taper in order to form a circular
nick, so that when fresh reels are used the threads can be pressed into
the nicks, and when the machine is put in motion for winding the
threads are carried round by the nicks and conducted by the guides on
to the reels. To the first guide stock is fixed one end of a rod, the other
end of which is held to another guide stock by a set screw, after as many
intermediate guide stocks are placed on the rod to correspond with the
number of reels. Each guide except the one connected with the first
guide stock jointed to the moveable plate is fixed to an arm on a vertical
spindle fitting a hole in the stock, there being at the bottom of the
spindle a screw on which there is a thumb nut employed to hold the
guide with such an amount of friction that it can be moved and
adjusted by the ends of the reels.
The first guide stock jointed to the moveable plate first adjusts itself
to the required reversing motion according to the length of its corre-
sponding reel, and as this stock is fixed to the rod which carries all the
other stocks they are traversed to the same extent, and the incon-
veniences arising from the inequalities of the shapes of the reels are
entirely obviated by the guides moving as required by means of the arms
on the vertical spindles fitted in the stocks, and kept at their proper
friction by the thumb nuts and screws.
In order to give the required pressure to the guides on the threads I
employ two two-armed levers, one arm of each having a slot fitting a pin
in each of the end guide holders, and the other arms are connected to a
rod having in the middle a slide fitted to guides on a stationary bracket,
there being a spring acting on one of the guides so as to press the slide
and give equal pressure on all the reels.
