PROVISIONAL SPECIFICATION.
Improvements in Pipes for Sanitary and other Purposes.
I, WILLIAM DEEMING, of Summit, Littleborough, in the County of Lancaster,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention refers primarily to earthenware or stone-ware pipes such as drain
pipes and the like though if desired it may also be applied to iron or other pipes
used for similar purposes and is designed with the object of providing an
inexpensive and easily made watertight and airtight joint between the ends of
two pipes.
The socket end and plain end of the pipes are made with a groove or recess either
in one or both into which a cement or suitable composition may be run when the
two parts of the pipes are in position.
In the form I at present prefer the socket on one pipe is formed with a groove
either rectangular oval circular V shaped or otherwise and the end of the other
pipe which fits into the socket has a corresponding groove or a series of small
grooves or indented rings which fit inside the socket. In large pipes the outside
lip only may be required. In some instances the flange forming the lip of groove
may be upon the small end of the pipe and fit into the socket on the other or two
flanges may be thrown onto the small end of the pipe and the socket end made
plain or otherwise formed to present a groove or grooves inside the socket into
which cement or composition in a liquid or semi-liquid state can be run to form a
joint.
Each socket is formed with two three or more holes or a single slot into which
the cement or composition is run when the pipes are laid in position.
When the joints are being made a little clay may be laid at the bottom of the
joint and on the pipe outside the socket to prevent the cement running out of the
joint before it sets.
The cement this run in forms a strong compact airtight and watertight joint which
will prevent the escape of either water or foul gases.

COMPLETE SPECIFICATION.
Improvements in Pipes for Sanitary and other Purposes.
1, WILLIAM DEEMING, of Summit, Littleborough, in the County of Lancaster,
Manufacturer 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 refers primarily to earthenware or stone ware pipes such as drain
pipes and the like though if desired it may also be applied to iron or other pipes
used for similar purposes and is designed with the object of providing an
inexpensive and easily made watertight and airtight joint between the ends of
two pipes.
The socket and spigot ends of the pipes are made so that when placed together
a groove or recess is formed into which a cement or suitable composition may
be run.
It will be fully illustrated in the annexed drawings in which sectional elevations
of my improved joint are shown in several forms,

page_text: I at present prefer one of the forms of joint shown in Figs. 1. 2 and 3 in which
both the socket and spigot ends of the pipe are formed with a groove or
recess A moulded therein which may either be rectangular, oval, circular, V, or
other shape.
In Fig. 4 the groove or recess A is formed by the shoulder B B moulded upon
the socket end and spigot end respectively.
In Fig. 5, the groove or recess A is formed in the socket end only.
In Fig. 6, the groove or recess A is formed in the spigot end only.
In Fig. 7, the socket end is made plain and a shoulder or projection B is formed
upon the spigot end which forms the groove or recess A.
In Fig. 8, the socket end is made with a lip or shoulder B¹ which when the spigot
end is inserted forms with it the recess A.
In each instance the groove or recess A is filled with a hard setting cement C
such as Portland cement run into the recess when the pipes are put together.
Each socket is formed with two three or more holes or a single slot into which the
cement or composition is run when the pipes are laid in position.
On the spigot end of the pipe in either of the joints shown in the drawings a
lip c may be formed to prevent the cement running out of the joints before
it sets.
The cement C thus run in forms a strong, compact, airtight, and watertight joint
which will prevent the escape of either water or foul gases.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
A pipe for sanitary or other purpose having a joint with a recess to receive a hard
setting cement formed as described and shown in either of the Figs. 1, 2, 3, 4, 5, 6,
7 or 8, of the drawings.
