PROVISIONAL SPECIFICATION.
Improvements in the Tubes and Driving Wharles of 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 tube and wharle used in
machinery for roving, spinning and twisting fibrous material in which the wharle
is not rigidly connected to the tube.
To carry out our invention we enlarge the top of the central hole through the
wharle, that is to say, we form a recess in the top of the wharle adapted to receive
the bottom end of the tube which fits loosely into it. The lower end of the tube
has an external flange, collar or equivalent projection and the said recess is
sufficiently large to admit this. To loosely secure the end of the tube in the
recess a wire or other ring surrounding the tube is sprung into the recess and into
an annular groove formed therein above the said collar.
To facilitate lubricating the tube from the wharle, and prevent the lubricant
being thrown out by centrifugal force at the junction of the wharle and tube, we
form a female screw thread in the interior of the tube so arranged that the end of
the thread scoops up the lubricant and causes it to pass up the tube. The said
thread is not necessarily continued to the top of the tube.
Dated this 20th day of June 1894.

Improvements in the Tubes and Driving Wharles of Machinery for
Roving, Spinning, and Twisting Fibrous Material.
We, Jons 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 per-
formed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to improvements in that type of tube and wharle used in
inachinery for roving, spinning and twisting fibrous material in which the wharle
is not rigidly connected to the tube.
To carry out our invention we enlarge the top of the central hole through the
wharle, that is to say, we form a recess in the top of the wharle adapted to receive
the bottom end of the tube which fits loosely into it. The lower end of the tube
as an external flange, collar or equivalent projection and the said recess is
sufficiently large to admit this. To loosely secure the end of the tube in the
recess a wire or other ring surrounding the tube is sprung into the recess and into
an annular groove formed therein above the said collar.

being thrown out by centrifugal force at the junction of the wharle and tube, we
form a female screw thread in the interior of the tube so arranged that the end of
the thread scoops up the lubricant and causes it to pass up the tube. The said
thread is not necessarily continued to the top of the tube.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indiente corresponding parts
in each of the figures.
Figure 1, represents an elevation of a wharle and tube made in accordance with
our invention and mounted upon a portion of a spindle.
Figure 2, represents a plan view of the same.
Figure 3, represents a sectional view of Figure 1 in which the spindle is broken
away to disclose the interior of the tabe.
Figure 4, represents a separate view of the said wire ring.
Figure 5. represents a separate elevation of the lower end of the tube.
Figure 6, represents a diametrical section of the wharte alone.
The central hole A for the spindle B through the wharle A is enlarged at the
top A adapting it to receive the collar C formed on the lower end of the tube C².
When the tube is in position the wire ring D is passed over it and is sprung into
the annular groove A and thus secures it."
We prefer to use the lubricator described in our Specification No. 11,112,
A.D. 1894, which affords a plentiful supply of lubricant to the wharle and we cut
a female screw thread C in the tube by which an ample supply of lubricant is
carried up the tube.
The wharle A is provided with the usual lugs A³, A³ or their equivalent to
engage and drive the bobbin.
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. The combination with a wharle having a recess at the top, of a tube the
bottom of which is adapted to fit into said recess, and a wire or other equivalent
ring adapted to be fixed in the said recess, substantially as herein shown and
described.
2. The combination with a wharle having a plain hole to fit the spindle, of a
tube loosely attached thereto and having a screw thread cut from the bottom
more or less to the top, substantially as herein shown and described.
