IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING YARNS
Year: 1885

page_text: I, WILLIAM SNOWDON, of Beckett's Bank Chambers, Leeds, in the county of
York, Consulting Engineer, do hereby declare the nature of my invention for
IMPROVEMENTS IN MACHINERY FOR SPINNING OR TWISTING YARNS, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
These improvements have special reference to a method of guiding the yarn on
to the bobbin from a concentric flyer.
The object of my invention is to save the extra length of spindle necessarily.
required when the bobbin is made to traverse backward and forward under the eye
of the flyer.
I accomplish this as follows:-I revolve the bobbin in the usual way, and
I cause the yarn to traverse backward & forward along the bobbin in place of
traversing the bobbin.
In order the more fully to explain the mechanism which I use I have annexed a
drawing of my arrangement, of which Fig. I is a longitudinal view (partly in
section) & Fig. 2 is a portion of a transverse section. The same letters refer to the
same parts.
The bobbin A., (which is revolved and acted upon in the usual way by the
pulley B.) is mounted on the central axis round which the flyer C. revolves. The
flyer, which is actuated by the belt pulley D., may consist of two end plates,
joined together by arms E. E. One or other of these arms is fitted with a sleeve F.
on which is mounted the yarn guide G., round which the yarn is conducted to the
bobbin. This sleeve is free to slide from end to end, but a key, or other equivalent,
prevents it turning on the flyer arm. On this sleeve is also fixed a runner H. If
necessary a sleeve may be fitted on each arm.
Outside the flyer are guides I. I., upon these guides I arrange to slide a plate or
disc K. This disc is traversed backwards & forwards the length of the bobbin by
the double screw L. L. The yarn entering at M., passes over the runners N. & O.
or over pawl pullies, & is guided by the sleeve runner G. on to the bobbin.

page_text: In traversing from right to left the disc K. acting on the runner H, pushes
forward the sleeve with the guide runner G., & on the return traverse the drag of
the yarn keeps the runner H. to the face of the disc, thus keeping a constant &
regular traverse of the yarn upon the bobbin.
The disc K. may be fixed on the guides I. I. & these made to slide in the
framing.
.
In cases where the drag of the yarn is not sufficient to keep the runner H. to
the face of the disc, the sleeve F. may be continued to the other side of the disc K.
& a second runner fixed on it, as shown on Fig. 3, so as to utilize both sides of the
disc & give a positive motion to the sleeve.
From what I have described it will be 'scén that one screw (or more if necessary,
to avoid a cross strain on the disc K) may be arranged to work a large plate, or
a series of plates, attached to one another, which in turn may actuate as many
sleeves on the arms of as many flyers as it may be found convenient to deal with.
Having now particularly described and ascertained the nature of my said
invention, & in what manner the same is to be performed, I declare that what
I claim is
A traversing sleeve F. on the arm of the flyer with its runner H. traversed by
means of the disc K. substantially as herein described and shown on the drawing.
Dated this twenty-seventh day of June 1885.
