PROVISIONAL SPECIFICATION.
An Improvement in or applicable to Rain-water, Ventilating, Soil,
Stack, Drain, and like Pipes.
I, JOHN GEORGE PAWSEY, of Wakering Avenue, Friars Park Estate, Shoe-
buryness, Essex, Plumber, do hereby declare the nature of the said invention
to be as follows:-
This invention relates to an improvement in or applicable to rain water pipes,
ventilating pipes, soil pipes, stack pipes, drain pipes, and the like, and has,
for its object, to enable an effective jointing of lengths of such pipes to be
secured in a ready and reliable manner and so as to absolutely prevent the
stopping from falling out or from being so affected by ordinary influences as
to allow of the escape of noxious gas or the like.
To this end, the invention consists in the formation of one end of each pipe
length with concentric tubular parts together forming an annular socket adapted
to contain the stuffing or joint forming material and also to receive the adja-
cent end of the pipe length to be connected in such manner as to cause the stop-
ping to form a joint both between the inner side of the inserted pipe end and
the inner tubular part of the socket and between the outer side of the inserted
pipe end and the outer tubular part of the socket, thus locating the pipe length
in a cushion of the stopping or joint forming material, and forming a double
or U-like joint which absolutely prevents the stopping from falling out or from
being driven out by any internal pressure and forms an hermetic joint prevent-
ing the escape of any noxious fumes from the pipe through the joints.
The improved joint also enables the stopping material to be inserted into the
socket before the pipe end to be connected is inserted thereinto and so enables
all parts of the joint to be thoroughly well got at and charged with the stop-
ping before the pipe end to be connected is inserted and pushed home.
The inner tubular part of the socket is preferably made a little lower than
the outer tubular part thereof so as to ensure the inner joint being well and
sufficiently packed, and, should a liquid or semi-liquid stopping material be
used, in vertically disposed pipes, to ensure the same running up to the top of
the inner joint and effectually filling the latter so as to prevent the lodgment of
any matter between the parts of the inner joint. The inner tubular part of the
socket is also bevelled off so as to offer no impediment to the passage of
anything falling down the pipe.

I, JOHN GEORGE PAWSEY, of Wakering Avenue, Friars Park Estate, Shoe-
buryness, Essex, Plumber, 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 relates to an improvement in or applicable to rain water pipes,
ventilating pipes, soil pipes, stack pipes, drain pipes and the like, and has for
its object to enable an effective jointing of lengths of such pipes to be obtained
in a ready and reliable manner; the improvement being particularly applicable
to vertically arranged pipes and being adapted to prevent the joint stopping
material from falling out or from being so affected by atmospheric or other
ordinary influences as to allow of the escape of noxious gases ascending or liquid
matters descending such pipes.
On the accompanying drawing, Figure 1, represents in sectional elevation a
pipe formed in accordance with the invention; Fig. 2, represents a plan thereof;
and Fig. 3, represents a sectional elevation of two pipe lengths showing the
improved joint.
To the end aforesaid, the invention consists in the formation of one end of
each pipe length with concentric tubular parts, a, b, which together form an
annular socket, c, adapted to receive the adjacent end, d, of the pipe to be con-
nected and also to contain the stopping or joint forming material, e, in such
a manner as to cause the stopping to close both the space between the inner
side of the inserted pipe end and the inner tubular part, b, of the socket,
and also that between the outer side of the inserted pipe end and the outer
tubular part, a, of the socket, thus locating the inserted pipe end in a cushion
of the stopping, e, which forms a double or U-like joint which absolutely pre-
vents the stopping from falling out or from being driven out by any internal
pressure and forms an hermetic joint preventing the escape of any noxious
gases or the like.
The improved joint, especially in its application to vertically arranged pipes,
is of special advantage in enabling the stopping material to be inserted into
the socket before the pipe end to be connected is inserted thereinto, so enabling
all parts of the joint to be thoroughly well got at and charged with the stop-
ping before the pipe end to be connected is inserted and pushed home. .
In such pipes, the inner tubular part, b, of the socket is preferably made a
little lower than the outer tubular part, a, thereof, so as to ensure the inner
joint, should a stopping be applied in a liquid or semi-liquid condition, being
well and sufficiently packed, and to ensure the same running up to the top of
the inner joint and effectually filling the latter. The inner tubular part of the
socket is also preferably bevelled off at its inner top edge so as to offer no impedi-
ment to the passage of anything falling down the pipe and to prevent the lodg-
ment of any matter between the parts of the inner joint.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
-
In rain-water, ventilating, soil, stack, drain and like pipes: the formation
of one end of each pipe length with concentric tubular parts which together form
an annular socket adapted to receive the adjacent end of the pipe length to be

page_text: connected and also to contain the stopping or joint forming material in such
manner as to cause the stopping to close the spaces between the inserted pipe
end and the inner and the outer tubular parts of the socket so as to locate the
inserted pipe end in a cushion of the stopping which forms a double or U-like
joint, as set forth.
