I, JOHN THOMAS WIBBERLEY, of Leicester, in the County of Leicester,
Mechanic, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR WINDING COTTON, SILK, WOOL,
OR OTHER THREADS ON SPOOLS OR REELS," to be as follows:-
I employ the ordinary right and left handed screws for traversing the
thread from end to end of the spool or reel, but instead of changing the
traverse by hand I change it by means of improved self-acting move-
ments. On the ordinary sliding shaft which carries the right and left
handed nuts I place an arm extending to the top of the machine and
fixed to a tube, which tube works loose on the ordinary sliding shaft
carrying at each end the right and left handed nuts. I also employ two
stays extending through a fixed plate on the top of the machine head and
connected to a slide working in guides or recesses in the fixed plate.
On the top of the stays I fix a plate which supports another movable
plate working in recesses and carrying at cach side a slide, catch,
spring, and adjustable screw, and near cach end of the said movable

page_text: plate there is a pin projecting from underneath and working in a slot in
the under plate. I also employ two levers, one at each end of the
tube, and placed between the tube and the stays. The bottom ends of
these levers press inwards against the ends of the tube and their
top ends against the projecting pins, the fulcrums of the levers pressing
against the stays. On the fixed plate on the head of the machine I place
two cam bars which are alternately pressed outwards by a bowl fixed to
the arm as it traverses to and fro with the sliding shaft and moved
inwards by springs. At the sides of the top movable plate there are
slide bars carrying catches, and to each bar is fixed a pin which passes
through a slot in the top moveable plate, and is connected to one end of
a spring the other end of which is attached to a pin fixed to the top
movable plate, so that when the slide bars and catches are moved in one
direction the springs shall give them the return movement. The catches
are employed for seizing and holding the upper part of the arm first at
one side and then at the other, and maintaining the proper nut upon its
screw, and as soon as the arm is released from one catch it is moved by
the cam bar and spring to the other side, and is held by the other catch.
The slide bars move to and fro with the movable plates, but they have
also independent sliding motions imparted to them for the purpose of
working the catches, there being two drop holders working in unison
with the cam bars to prevent the top plate from moving until required.
The guide stock works in a slide on an arm fixed to the sliding shaft,
the necessary friction being given to the stock by means of a spring, and
the stock is brought forward for a fresh winding by means of a lever.
The traversing motions are alternately changed by the sides of the guide
coming in contact with the end of the reel, until at the completion of the
winding a self-acting stopping motion stops the machine. When the
side of the guide comes in contact with the end of the reel it becomes
stationary and allows the tube and arm on the sliding shaft to move and
shift its corresponding lever, thereby moving the top movable frame
carrying the catches in the opposite direction and relieving the top of the
arm from the catches, and then the spring of the cam bar exerts its
power and presses. forward the cam bar and shifts the bowl to the other
side so that the top of the arm shall be caught by its corresponding catch
and one of the nuts removed from one screw and the other nuit put on
the other screw. For stopping the machine after the winding on I
employ a stationary bar having at the top a double lever, and fix to the
setting on or stop rod a lever which can be acted upon by a projection on

page_text: the horizontal ratchet wheel and measuring disc. When the required
number of layers is wound on the reel the projection raises the lever from
a detent and allows a spring to shift the stop rod and fork and bring a
break against the driving pulley, and at the same time a finger on the
stop rod comes in contact with the double lever which shifts the holding
catch for enabling the ratchet wheel to be liberated and readjust
itself by its spring. The reel is placed upon the ordinary spindle to be
worked and is removed by means of a lever. In order to stop the
machine when a thread breaks I employ a double lever jointed to the
guide stock arm and form the end of the stop rod of such a shape that
one arm of the lever can act upon it when the other arm is lowered.
One arm of the lever is weighted, and the thread when entire supports
this arm, but when the thread breaks this arm falls and the other arm
rises and turns the stop rod out of its detent and causes the stoppage of
the machine.
