PROVISIONAL SPECIFICATION.
Improvements in Stoppers for Stoneware Pipes, Gullies, Traps, and
Junctions.
We, GEORGE MARLOW REED, of 4, Byron Villas, Bound's Green, in the County
of Middlesex, Agent, and WILLIAM HENRY KNIGHT, of 12, Feriestone Road,
Hornsey, in the same county, Sanitary Engineer, do hereby declare the nature
of this invention to be as follows:
When laying drain pipes, certain junctions have to be left for connection to the
drains from houses which are to be subsequently built. Traps and gullies are
also provided with what are termed sight holes, by which a rod or other appliance
may be inserted, to remove an obstruction in the diain or connection with the
sewer.
All these openings have to be closed by stoppers, which have to be removed
for any of the purposes above named
Hitherto these stoppers have been liable to be forced out of their seating by
back pressure of any kind in diain trap, gully, or junction, a result which is
obviously inconvenient, as the object in having a trap is thus overcome, and sewer
gas escapes.
Now the object of the present invention is to provide a simple and efficient
stopper for stoneware pipes, junctions, traps, gullies, or other appliance where
such a stopper might be required, which will be able to resist the back pressure
before referred to, and which will not piesent any difficulty in making a con-
nection where required
In carrying out this invention, across the mouth of the socket or other orifice,
side bars are formed, which slightly overlap the socket
Where there is no socket, a shallow recess 18 formed, so that there will be a
space below the bars.
The stopper 18 formed with an oval head, the smaller diameter being equal to
the diameter of the stopper or plug, and slightly less than the distance between
the bars
Means will be provided whereby the stopper may be turned in its seat, whereby
the ears formed by the larger diameter will be brought under the bars, which
will thus firmly hold the stopper against any back pressure.
In junctions and other places where a connection is to be made, the bars will
be so formed that they may be readily knocked off with a gentle blow from a
hammer, without destroying the continuity of the wall of the socket.
Dated this 23rd day of December 1898.

Junctions,
We, GEORGE MARLOW REED, of 4, Byron Villas, Bound's Green, in the County
of Middlesex, Agent, and WILLIAM HENRY KNIGHT, of 12, Ferrestone Road,
Hornsey, in the same county, Sanitary Engineer, do hereby declare the nature
of this invention and in what manner the same 18 to be performed, to be particu-
larly described and ascertained in and by the following statement:
When laying pipe sewers, certain junctions have to be left for connection to the
drains from houses which are to be subsequently built Traps and gullies are
also provided with what are termed sight-holes, by which a rod or other appliance
may be inserted, to remove an obstruction in the drain, or connection with the
Bewer.
All these openings have to be closed by stoppers, which have to be removed
for any of the purposes above named
Hitherto, these stoppers have been liable to be forced from their seating by
the back pressure of gas or water in the diain, trap, gulley, or junction, a result
which is obviously inconvenient as the object in having a trap is thus overcome,
and sewer gas escapes
Now the object of the present invention is to provide simple and efficient
means for stopping stoneware pipes, junctions, traps, gullies, or other appliances,
where such stopping might be required, and which will be able to resist the back
pressure before referred to, and which will not present any difficulty in making
a connection when required.
In carrying out this invention, across the mouth of the socket or other orifice,
side bars are formed, which slightly overlap the socket
Where there is no socket, a shallow recess is formed, so that there will be a
space below the bars.
The stopper 18 formed with an oval head, the smaller diameter approximating
to the diameter of the stopper or plug, and slightly less than the distance between
the bars
Means will be provided whereby the stopper may be turned in its seat, so that
the ears formed by the larger diameter of the oval will be brought under the bars,
which will thus firmly hold the stopper against any back pressure.
The bars will be so formed that they may be readily knocked off with a gentle
blow from a hammer, without destroying the continuity of the wall of the
socket, when it is desired to make a connection.
In the accompanying drawings,
Fig 1 shows in elevation, partly in section, a socket provided with the stopper.
Fig 2 18 a plan view of the socket, and
Fig. 3 18 a top plan view of the stopper.
Fig 4 shows in elevation, partly in section, a pipe end adapted to receive a
stopper, and
Fig. 5 is a plan view of the same.
Fig 6 is a side view, and
Fig 7 a plan view of the stopper for the same.
Refening now to Figs 1, 2, & 3, A 18 the pipe, and B the socket Across the
mouth of the socket, are formed the bars C, which partly overhang the socket
The stopper proper is formed with a circular part D, which (when in position)
rests on the bottom of the socket, and with a more or less oblong or oval head E.
The smaller diameter of the oval approximates to the diameter of the part D, and

the oval, which approximates to that of the socket, enter under the bars C, when
the stopper is turned round by the handle F, and thus hold the stopper securely
in position.
In order to make a tight joint, a packing is employed, which may consist of
a ring of bitumen, or other suitable material, cast on the part D of the socket,
while a similar ring is cast in the socket, the two rings fitting accurately one
within the other.
This packing is necessitated from the fact that, during firing, the stoneware
warps more or less, and true circles or surfaces cannot be obtained without the
packing
Referring to Figs. 4 to 7, in adapting the invention to a pipe end, a recess
is formed in the wall of the pipe, near the end, with bars

across, as in the
The stopper is slightly modified in shape, though, for all practical purposes, it
is the same as before.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same 18 to be performed, we declare that what
we claim is :-
The means for stopping stoneware pipes, gullies, traps, and junctions, and
consisting of bars formed across opposite sides of the mouth of a socket or pipe
end, a stopper proper formed with lugs to take under the bars, and packing
between the stopper and the socket, as and for the purpose herein shown and
described.
