PROVISIONAL SPECIFICATION.
Improvements in Couplings for Glass Tubes or for Tubes Lined
with Glass.
We DAN RYLANDS of Stairfoot near Barnsley in the County of York Glass
Bottle Manufacturer and ROBERT MORANT 236 Doncaster Road Barnsley
aforesaid Engineer, do hereby declare the nature of this invention to be as
follows:-
--
This invention consists of a socket union made in two parts one to work inside
the other in such a manner that either part can be made to work independently
as two ordinary sleeve sockets or both to be turned together as one ordinary
sleeve socket, the object being to draw the end of one pipe or tube tightly against
another pipe or tube by turning one part of the union instead of turning the tubes
as must be done when ordinary sleeve sockets are used. The union is made in two
parts, the smaller or tail part is made similar to an ordinary sleeve socket, but with
a small flange or projection at one end around or partly around the outside circum-
ference. The larger or head part is made similar as above described but instead of
the flange a circular chamber is formed at one end large enough to admit the flange
of the tail part and long enough to allow the end of the chamber to be lapped over
toward the inner circumference so securing both parts together in such a manner as
to allow either part to turn independently of the other. A suitable washer of
gutta percha, or india rubber or other suitable substance coated with shellac serves
to render the joint airtight.

Improvements in Couplings for Glass Tubes or for Tubes Lined
with Glass.
We DAN RYLANDS of Stairfoot near Barnsley in the County of York, Glass
Bottle Manufacturer, and ROBERT MORANT, 200, Doncaster Road, Barnsley
aforesaid, Engineer, 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:-
This invention consists of a socket union made in two parts, one to work inside
the other in such a manner that either part can be made to work independently
as two ordinary sleeve sockets, or both to be turned together as one ordinary
sleeve socket, the object being to draw the end of one pipe or tube tightly
against another pipe or tube by turning one part of the union instead of
turning the tubes as must be done when ordinary sleeve sockets are used.
In the accompanying drawings,
Fig. 1 is an elevation in section of our invention as applied to the jointing or
coupling-up of glass tubes.
Fig. 2 is an clevation of the same.
Fig. 3 is a sectional elevation illustrating the coupling-up of glass-lined iron or
metal tubes.
Fig. 4 is an end view of the coupling.
In Figs. 1, 2, 3, and 4, a is the internally-threaded tail part made in a similar
manner to an ordinary sleeve socket but with an annular flange or projection b
formed on it at one end around or partly around the outer circumference. The

page_text: larger or head part e, also internally threaded, is formed into a circular chamber
or enlargement at d large enough to admit the flange of the tail part and
long enough to allow the end of the chamber to be lapped over towards the inner
circumference, thus securing. both parts together in such a manner as to allow
either part to be turned independently of the other, or instead of the end of the
chamber being lapped over, an externally-threaded ferrule may be screwed into
the end of the chamber as shown at e (Fig. 3).
A suitable jointing washer of gutta percha, rubber, or other suitable substance
(which may be coated with shellac) serves to render the joint tight.
The manner of coupling-up two pipes by the above-described coupling is as
follows: The united couplings being screwed on to the end of the pipe (Fig. 1),
the jointing ring being placed in position as shown, the pipe y can now be screwed
into the tail part a till the end of the pipe comes into contact with the jointing ring.
The pipes being held stationary and the tail part being turned will result in the ends
of the two pipes being drawn together thus compressing the jointing ring and
making an efficient and pressure-tight joint. It will be seen that the same end can
be attained by turning the head portion as by turning the tail portion, and that the
coupling can be used as an ordinary sleeve socket.
Having now particularly described and ascertained the nature of our said.
invention, and in what manner the same is to be performed we declare that what
we claim is:-
1. The improved socket union for coupling glass tubes or tubes lined with glass
as herein described and illustrated.
