PROVISIONAL SPECIFICATION.
Improvements in or relating to the Joints of Sanitary, Earthenware,
and other similar Pipes.
We, J. DUCKETT AND SON LIMITED, of Mitre Sanitary Works, Burnley, in
the County of Lancaster, Sanitary Ware Manufacturers, and FRED SMITH
BUTTON of 13, Palatine Square, Burnley aforesaid, Civil Engineer, do hereby
declare the nature of this invention to be as follows:-
Our invention consists in improvements in or relating to the joints of sanitary,
earthenware, and other similar pipes, and particularly to that class of joint in which
rings or collars of bituminous cement or other suitable composition or material are
cast upon the exterior of the spigot ends and the inside of the sockets of the
earthenware or other pipes whereby a close fit is insured, when the spigot end is
inserted into the socket.
In carrying our improvements into effect, we cast the collars of bituminous
cement or other suitable composition or material as usual and by preference the
full depth of the socket and a corresponding depth on the spigot end of the pipe.
We form in each collar an annular groove or recess preferably undercut or dovetail
in cross section, so that when the spigot end is fitted into the socket, the two
grooves in the bituminous cement or like collars come together, and form an annular
channel, somewhat of the shape of the letter X in cross section. A hole (or holes)
is formed in the socket end of the pipe communicating through a hole (or holes)
made in the cement collar with the annular channel, and Portland or other suitable
cement is run through this hole to completely fill the annular channel, and effectually
close and seal the joint, as well as to form a key when set to unite the pipes firmly
together.
A feature of our invention is that the annular grooves or recesses do not
penetrate to the pipes through the collars of bituminous cement or like material
so that such collars are not interrupted or divided as in some joints of the same
class.
We do not limit ourselves to the X section, as the annular channel may be of
any other suitable form.

page_text: performed to be particularly described and ascertained in and by the following
statement :-
Our invention consists in improvements in or relating to the joints of sanitary,
earthenware, and other similar pipes, and particularly to that class of joint, in
which rings or collars of bituminous cement or other suitable composition or
material are cast upon the exterior of the spigot ends and the inside of the sockets
of the earthenware or other pipes, whereby a close fit is insured when the spigot
end is inserted into the socket.
In carrying our improvements into effect, we cast the collars of bituminous
.cement or other suitable composition or material as usual, and by preference the
full depth of the socket, and a corresponding depth on the spigot end of the pipe.
We form in each collar an annular groove or recess preferably undercut or dovetail
in cross section, so that when the spigot end is fitted into the socket, the two
grooves in the bituminous cement or like collars come together, and form an
annular channel somewhat of the shape of the letter X in cross section. A hole
(or holes) is formed in the socket end of the pipe communicating through a hole
(or holes) made in the cement collar with the annular channel and Portland or other
suitable cement is run through this hole to completely fill the annular channel, and
effectually close and seal the joint as well as to form a key when set to unite the
pipes firmly together.
A feature of our invention is that the annular grooves or recesses do not
penetrate to the pipes through the collars of bituminous cement or like material,
so that such collars are not interrupted or divided as in some joints of the same
.class.
We do not limit ourselves to the X section, as the annular channel may be of
any other suitable form.
For the purpose of more clearly explaining our invention, we have prepared a
drawing, which shews a section of our joint; and have placed letters of reference
:thereon.
A is part section of the spigot end of a pipe. B is part section of the socket of
a pipe. C. C are collars of bituminous cement cast on the spigot and in the socket
of the pipes. D is an opening through the socket of the pipe and through the
socket collar of bituminous cement, which is formed for the purpose of admitting
Portland or other suitable cement to the annular channel E: this latter is formed
preferably dovetail in section.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The method and means of jointing sanitary, earthenware or other similar
pipes, substantially as herein described, and as illustrated on the accompanying
.drawing.
