PROVISIONAL SPECIFICATION.
Improvements in Machinery for Roving, Spinning, and Twisting
Fibrous Material.
We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower
Green Shed, Leeds Road, Bradford, in the County of York, Spinners, do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in that type of machinery for roving,
spinning and twisting fibrous material in which tubes are employed having a helical
or spiral groove cut or formed in the interior of the wharle and tube and extending
from the bottom more or less to the top of the tube for the purpose of conveying
the lubricant up the tube. The object of the said improvements is to prevent an
excessive quantity of lubricant passing up the tube, as well as keep fibres and
dirt from being drawn into the said groove.
For this purpose we do not extend the said groove down to the bottom of the
tube but terminate it a suitable distance above thus leaving a plain or ungrooved
portion at the bottom.
A convenient way of making the tubes and wharles in this way is to bore the
lower portion of the wharle the same diameter as the spindle and enlarge it above
to receive the lower end of the tube which latter may be spirally grooved from
the bottom.
As a modification the tube may be continued to the bottom of the wharle and an
annular groove formed a little way up from which the spiral groove commences.
Dated this 16th day of August 1894.

We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower
Green Shed, Leeds Road, Bradford, in the County of York, Spinners, 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:-

Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding
parts in each of the figures.
Figure 1, represents a longitudinal section of a tube and wharle made in
accordance with our invention.
Figure 2, represents a transverse section of the same on the line a, b Figure 1.
Figure 3, is a similar section on the line y, z.
The lower portion A of the hole through the wharle B is bored to fit the
spindle on which the wharle is intended to revolve, and the upper portion A² of
the said hole is made large enough to receive the lower end of the tube C which
is tightly fixed therein. The helical groove C2 is cut inside the tube from the
bottom upwards.
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:
A wharle and tube for roving, spinning and twisting machinery having an internal
spiral groove commencing a suitable distance from the bottom, substantially as
herein shown and described and for the purpose specified.
Dated this 17th day of May 1895.
