Improvements in Apparatus for Traversing the Yarn Guides
Employed in Machines for Preparing and Spinning Cotton and
other Fibrous Materials.
I, JOHN FRAY POOLE of Deane Mill, Bolton in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of my said invention to be as
follows:
This invention relates to improvements in apparatus for traversing the yarn
guides employed in machines for preparing and spinning cotton and other fibrous
materials and is designed to produce an automatic and regular to and fro movement
of the same so as to dispense or reduce the liability of the rollers being indented,
cut or nicked at each end as is the case at present through the unequal traverse
motion given to the yarn guides. It is well known that this defect arises from the
reduced speed of the traverse when changing from one direction to the other. To
overcome this defect and produce a regular motion so that the ends of the rollers
will wear equally with the middle portion I mount on the roller shaft a worm
gearing with a worm wheel suitably mounted on a centre attached to the framework
of the machine. On this centre is mounted an elliptical wheel gearing with an
elliptical wheel on a centre. To the latter or the elliptical wheel is attached a disc
and cam operating a lever coupled to a connecting rod attached to the traverse rod
or slide attached to the yarn guide. The elliptical wheels are proportioned so that
the traverse is uniform or thereabouts, throughout the traverse of the yarn guides.

I, JOHN FRAY POOLE of Deane Mill, Bolton in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of my said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—

DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal side elevation of my improved apparatus for traversing
the yarn guides employed in machines for preparing and spinning cotton and other
fibrous materials-
Fig. 2 is an end view-Fig. 3 a plan-Fig. 4 a side view of cam, and
Fig. 5 a plan of my improved apparatus applied.
On the roller shaft A I mount the worm B gearing with the worm wheel C
mounted on the centre D attached to the fixing E on the framework F of the
machine. On the centre D is mounted the elliptical wheel G gearing with the
elliptical wheel H on the centre I. To the latter or the elliptical wheel H is
attached, by the screws J, the disc and cam K, which, as the latter rotates, operates
the lever L coupled to the connecting rod M attached to the traverse rod N by the
centre O. On the traverse rod N are mounted the yarn guides P. To ensure of
the lever L being held against the cam K the traverse rod N is provided with the
pin or centre R to which is coupled the spiral spring S; the other end of the latter
being secured to the framework T.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
In apparatus for traversing the yarn guides employed in machines for preparing
and spinning cotton and other fibrous materials at an uniform speed the use of the
elliptical wheels G and H and the cam K, applied and operating substantially as
described and as illustrated in the drawings.
