EDMUND ALDERSON SANDFORD FAWCETT, 1, Victoria Street, Westminster,
London, S.W., Civil Engineer, do hereby declare the nature of this invention to
be as follows:
A combined stopper and connector for sewers, drains and the like, formed of
(1) A spigot and socket stoneware, fireclay, or earthenware, pipe sealed at the
socket end with a disc or plate of the same or other suitable material, the disc or
plate being partially cut through or made thin in a circle or other suitable shape
in such a manner that when required the disc or plate or a portion thereof may
be readily broken out or off leaving the pipe and socket intact for the continuation
of the sewer or drain or for any other purpose required.
Or (2) the eye or junction of the drain or sewer may be sealed with a similar
disc or plate without the use of a spigot and socket pipe.

A Combined Stopper and Connector for Sewers, Drains and the like.
I, EDMUND ALDERSON SANDFORD FAWCETT; 1, Victoria Street, Westminster,
London, S.W., Civil Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:
―
The principal object of this invention is to make provision for house connections
to drains but the invention is also applicable for stopping the ends of drains or
branches which may afterwards have to be continued and in other cases in which
access to the interior of a pipe is necessary.
For these purposes it is usual either to plug the end of the junction or pipe by
cementing or claying a disc into the socket. The clay however is apt to dissolve
and in chipping away a cemented stopper there is great danger of injuring the
socket.
According to this invention the end of the branch or pipe to which a connection
may afterwards have to be made is closed with a disc preferably made in one piece
with the pipe or socket a notch being formed around the disc so that it may be
readily broken off leaving the pipe or socket intact for the continuation of the
drain or the like.

page_text: The drawing is a longitudinal section of a junction pipe made according to this
invention.
a is the pipe, a¹ its socket, the branch and 6' its socket, c is the disc made
in one piece with the socket b and closing its end. is a notch made all around
the end of the socket bl. A similar notch may also be made inside.
In cases where the pipes are to be salt glazed a hole should be made in the disc c
to allow of the circulation of the fumes. After firing this hole is closed by
cementing in a stopper e as shown.
Although I prefer to make the disc e in one piece with the socket or pipe it may
be cemented in. The socket in this case should be made longer than usual and a
rebate formed beyond the notch to receive the disc or the notch d may be made
around the junction of the pipe band the socket so that the whole socket with
the disc in it can be removed leaving the end of the pipe b to receive the socket of
the next pipe.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I am aware that pipes and conduits have been longitudinally notched so that
the upper part can be removed and I make no claim to this but what I claim is :-
1. A pipe closed at one end by a disc and having a notch in it around the
disc.
2. A pipe substantially as described and shown in the drawing.
