Potter do hereby declare the nature of this invention to be as follows:-
This Invention has for its object improvements relating to the joints of stone-
ware pipes.
When it is intended. to, connect stoneware pipes by means of cement joints
I forin the same in the following manner; I line the sockets and I tip the ends of
the pipes with composition as is at present commonly practiced. I also provide
near the ends of the pipes a collar moulded in the stoneware and this collar is
made to support a ring of gasket or other pliable material against which when the
pipes are laid together the socket of the next pipe abuts.
.
In the side of each socket there is a hole or holes by which, the cement to
complete the joint is run into the cavity of the socket and between the tipped end
of the pipe within the socket and the gasket ring which closes the mouth of the
socket.
Advantages of this arrangement are that whilst the pipes are being laid there is
sufficient flexibility in the joints to admit of the pipes being accurately placed in
the positions required whilst afterwards à complete and impermeable closing of the
joints is effected. The joint also is one which is convenient for manufacture as
well as for use.

In order that my said Invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of portions of two stoneware pipes jointed together
in accordance with my invention.
Figure 2 is a longitudinal section of the same.
a is the socket it is tipped or lined with composition a¹ to make it truly
cylindrical within as is commonly practiced except that the lining is continued for
a shorter distance along the socket. a² is a hole provided through the socket.
b is the end entering the socket it has a collar b¹ moulded upon it and at b² it is
tipped with composition. c is a gasket ring which is interposed between the
collar b' and the end of the socket a, in such a manner that it closes the mouth of
the socket. d is cement which is poured in whilst sufficiently liquid to flow so as
to fill the cavity between the gasket ring c. and the composition lining and tip a¹
and 62. The cement is introduced when the pipes have been laid and finally
arranged in position.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination in a pipe joint of the parts a, a¹, b, b¹, b³, c and d substan-
tially as described.
2. My improvements relating to the joints of stoneware pipes substantially as
described.
