"IM-
PROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS MATERIALS."
Our Invention relates to that system of spinning and doubling known as the
ring and traveller, and consists, firstly, in an arrangement for winding the yarn on
the bobbin or spool, our object being to so perform the operation that waste may be
avoided when the unwinding takes place. To effect this we cause the winding to
commence at the bottom of the bobbin with a short chase, every lift of the ring
plate making it about a thread longer, thus causing the thread to be always tight
at the nose, at the same time allowing the ring plate to come down after each lift to
the bobbin head until the bobbin is large enough, and then the ring begins to rise
and build the bobbin parallel. To effect these objects we employ a sliding carriage
caused to traverse by a broad heart wheel or cam of conical form acting against a
bowl connected to the said carriage. This bowl is borne towards the heart wheel
by the weight of the ring rail or plate and is caused to traverse the conical surface
of the wheel or cam by means of a screw actuated by a click or ratchet, or by similar
means, whereby the sliding carriage is caused to move through varying spaces and
operate in proportion upon the lifting rail or plate. When the bowl has travelled
across the wheel or cam it has finished the laying of the yarn for the foundation of
the bobbin or spool, and is at the full length of the chase and the carriage is moving
through the full space, which by means of a second lever and catch sliding upon
an incline causes a second motion to lift the ring, rail, or plate at such speed as
may be given to it by the number of teeth in the second ratchet in order to
build the body of the bobbin or spool parallel.
Another part of our Invention relates to an arrangement for doffing and for
adapting empty bobbins. For these purposes we adapt a shaft to the front of

page_text: the lifting plate, such shaft carrying an arm or arms which are provided with
projecting parts which when the arm or arms are turned upwards pass beneath
the bottom of the bobbin, while at the same time a clip or jaw also carried by the
said arms embraces and holds the filled bobbin or spool. The lifting plate being
now caused to rise elevates the bobbin or spool above the top of the spindle,
and the aforesaid arms having been turned over on their centre the filled bobbin
may be removed. For adapting empty bobbins there is a shaft at the back of the
machine which by means of arms carries a bar provided with clips or jaws to
which the empty bobbins are adapted. When the doffing has been accomplished
this bar is turned downwards so as to bring the bobbins over the spindles, and
the clips or jaws having by this movement been opened the bobbins drop down-
ward into the spinning position. To permit of this movement the guide board
is hinged so as to turn downward when released from a support, but the front
part may be hinged to turn upward as usual. In order to prevent the end from
being carried backward by the turning down of the guides we form the said
guides without an enclosing front, so that they pass freely away from the ends.
