PROVISIONAL SPECIFICATION.
Improvements in Machinery for Spinning or Winding Yarns or
Threads.
We, JOHN PEARSON, Managing Director of the Firm of Willey and
Pearson Limited of Trafalgar Works Halifax, in the County of York, Spinners
and JOHN WILLIAM THORNTON of the same place, Mill Manager, do hereby
declare the nature of this invention to be as follows, that is to say:-
It relates to improvements in machinery for spinning or winding yarns or
threads of fibrous substances.
As is well known when the yarns or threads are wound upon tubes or spools or
when they are wound to form cops, often considerable inconvenience is experienced
by reason of the outer ends or noses of these tubes spools or cups slipping off or
becoming damaged and to obviate this difficulty and loss is the object of this
invention.
This object we attain by arranging the traverse mechanism so that each coiled
layer of yarn is formed in a zig-zag manner on the top of the lower layer or on
the tube or spool, thus one part is interlocked with another so that its detachment
particularly when the threads are of some classes of fibrous substances is to a great
extent prevented.
The traverse mechanism we employ may be any one of those well known and at
present in use, but the cam that operates same is formed to have three risen and
three depressed parts either of equal or variable degree, by which means during
each revolution of said cam the lifter rail is raised and lowered three times.
The runner or bowl acting on the peripheral surface of the cam is made of such
dimensions as to enable it to follow said surface throughout its entirety thus the
exact movements desired may be derived from the cam.

COMPLETE SPECIFICATION.
Improvements in Machinery for Spinning or Winding Yarns or
Threads.
We, JOHN PEARSON, Managing Director of the Firm of Messrs. Willey and
Pearson Limited of Trafalgar Works, Halifax in the County of York, Spinners
and JOHN WILLIAM THORNTON of the same place, Mill Manager, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
It relates to improvements in machinery for spinning or winding yarns or threads
of fibrous substances.

page_text: As is well known when the yarns or threads are wound upon tubes or spools or
when they are wound to form cops, often considerable inconvenience is experienced
by reason of the outer ends or noses of these tubes, spools or cops slipping off or
becoming damaged and to obviate this difficulty and loss is the object of our said
invention.
In the accompanying sheet of drawings which are illustrative of our invention.
Fig. 1 is an elevation of a sufficient portion of a well known kind of lifter or
traverse mechanism for a spinning frame, to show the application thereto of our
improved form of operating cam.
Fig. 2 is a drawing in detail illustrating the formation of cam employed for
carrying our invention into effect.
We attain the object of our invention by arranging the traverse or lifter
mechanism so that the movements it transmits to the bobbins, spools or spindles
upon which the yarns or threads are being wound are such that each coiled layer
of said yarn is formed in a zig-zag manner on the top of the lower layer or on the
tube or spool, thus one part is interlocked with another so that its detachment
particularly when the threads are of some classes of fibrous substances is, to a
great extent, prevented.
The traverse mechanism as the levers a b and other parts may be any one of
those well known and at present in use, the one shown being perhaps as well known
as any of the varied kinds, but the cam c that operates same is formed to have
three risen parts d d' de preferably of variable degree (as shown by the broken
lines ghk) and three depressed intervening parts, while the rising side e of
each part d d d is made to occupy more (and consequently a longer time in
each revolution) of the peripheral surface of the cam c than does the descending
side, by which means during each revolution of said cam c the lifter rail is
raised and lowered three times and the three series of wraps of yarn on the
bobbins, spools or the like will have been formed to overlie or interlock one with
another.
The runner or bowl m acting on the peripheral surface of the cam c is made of
such dimensions relatively with the shape of said periphery as to enable it to
follow said surface throughout its entire length thus the exact movements desired
may be derived from the cam c.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In the spinning or winding of yarns or threads, means whereby the several
layers may be made to interlock or overlie each other substantially as specified.
2. In spinning or winding machinery a cam as the cam c having three distinct
rising parts shaped and arranged relatively with. each other substantially as herein
set forth and described.
