PROVISIONAL SPECIFICATION.
Improvements in or connected with Drain Pipe Joints and
the like.
I, JAMES WEATHERLY of 39 High Street, Lambeth in the County of Surrey,
Potter do hereby declare the nature of this invention to be as follows:
--
In carrying out my invention I make the socket of the pipe tapered shape and
as the thickness of the shoulder of the pipe is the same as the thickness of the pipe
at the spigot end it so forms a level invert.
By the addition of a small inner flange at the extreme end of the socket which
extends around the lower half of the socket a groove is formed for the reception
of cement, grout, or other jointing material. By means of the said inner flange the
jointing is prevented from slipping back or falling out and the spigot is firmly
bedded on the lower half of the pipe leaving easy access to the top part of the
joint in the usual manner thereby securing a tight joint.

Improvements in or connected with Drain Pipe Joints and
the like.
I, JAMES WEATHERLY, of 39 High Street, Lambeth, in the County of Surrey,
Potter, 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 :-
In carrying out my invention I make the socket of the pipe tapered shape and
as the thickness of the shoulder of the pipe is the same as the thickness of the pipe
at the spigot end it so forms a level invert.
By the addition of a small inner flange at the extreme end of the socket which
extends around the lower half of the socket a groove is formed for the reception
of cement, grout or other jointing material. By means of the said inner flange
the jointing is prevented from slipping back or falling out and the spigot is firmly
bedded on the lower half of the pipe, leaving easy access to the top part of the
joint in the usual manner thereby securing a tight joint.

page_text: A flanged is made in the socket end b at its outer end; it extends half way
round the socket.
When making the joint the lower part of the socket is lined with cement or
jointing material, the spigot end of the pipe is laid in place and pressed down;
afterwards the upper part of the socket is filled. The taper form facilitates that
complete filling of the socket which is necessary to form a sound joint.
The flange d serves two purposes; it aids in centering the spigot end of the
next pipe which rests upon it so that a level invert may be formed at the shoulder c
and it aids in retaining the cement or other jointing material in the taper socket,
so the joint can be made in the manner described which it could not be if the
cement or jointing material were not effectually supported in the socket beneath
and around the spigot end which the socket receives.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. A pipe with a tapering socket and a flange in the socket passing around it on
its under side and operating substantially as described.
2. A pipe joint substantially as described and shown in the drawings.
Dated this 16th day of October 1895.
