I GEORGE EDMUND ARNOLD, of the Patent Free-stone. Works, West Marina,
St. Leonards, in the County of Sussex, Manager of Works, do hereby declare the
nature of this invention to be as follows:-
My invention relates to an improved joint connection for sanitary drain, and
other pipes, and it has for its object facilitating the making of the joints of the
said pipes.
Instead of making each pipe with a spigot and socket end as is usual, I make a
half socket on each end of the pipe, the half socket on one end being on the opposite
side of the pipe to the half socket on the other end. Each half socket has a circum-
ferential groove formed in its inner face, and round the ends of the pipe where the
half sockets cease are small flanges of a suitable size to fit in the grooves in the
half sockets, so that when two pipes are joined together the small half flanges fit
and coincide with the half sockets, thus making a good and reliable joint, and one
that can be conveniently packed. I sometimes make the half sockets without the
grooves, and merely allow the half flanges to lie in the half sockets.
In laying these pipes they are so arranged that the half socket of 'the last pipe
laid is at the bottom where it can easily be packed or cemented ready to receive the
next pipe with its half socket at the top.

Improvements in the Joint Connections of Sanitary, Drain, and
other Pipes.
I GEORGE EDMUND ARNOLD, of the Patent Freestone Works, West Marina,
St. Leonards, in the County of Sussex, Manager of Works, 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 :-
My invention relates to an improved joint connection for sanitary, drain, and
other pipes, and it has for its object facilitating the making of the joints of the
said pipes.
Instead of making each pipe with a spigot and socket end as is usual, I make a half
socket on each end of the pipe, the half socket on one end being on the opposite side
of the pipe to the half socket on the other end. Each half socket has a circum-
ferential groove formed in its inner face, and round the ends of the pipe where the
half sockets cease, are small flanges of a suitable size to fit in the grooves in the half
sockets so that when two pipes are joined together the small half flanges fit and
coincide with the half sockets, thus making a good and reliable joint, and one that
can be conveniently packed. I sometimes make the half sockets without the grooves,
and merely allow the half flanges to lie in the half sockets. In laying these pipes.
they are so arranged that the half socket of the last pipe laid is at the bottom, where
it can easily be packed or cemented ready to receive the next pipe with its half
socket at the top.
In order that my invention may be fully understood I herewith append a drawing
illustrating it and the manner of carrying the same into practical effect.
Figure, I is a view in longitudinal elevation-partly in section-showing the joints
of pipes constructed according to my invention. Figure 2. is a view in end elevation
of a pipe showing the construction of the joint; and Figure 3. is a view in plan of a
pipe showing the formation of the respective joint ends thereof. Figures 4 and 52
are views in longitudinal elevation-partly in section-and plan, respectively, showing t
my invention, as applied and carried out with pipes of an eliptical section, and
Figures 6 and 7. are views in longitudinal elevation-partly in section-and plan,
respectively, of a modification, of my invention.
Throughout the several views similar parts are marked with like letters of a
reference.
Referring to Figures 1. 2. 3. 4 and 5: On each end of each length of pipe A is
formed a half socket A¹i.e., a socket extending round half the circumference of the
said pipe. The half socket on one end of the pipe is diametrically opposite to that
on the other end of the pipe, for a purpose that will presently be made clear.
In each half socket an internal circumferential groove a¹ is formed. On each end
of the pipe where the half sockets A' cease, are formed small flanges a. These
flanges are of a suitable size to fit freely within the grooves a in the half
sockets A¹.

page_text: In laying these pipes, each pipe is laid so that its open end onto which the next
pipe is to be fitted, bas the half socket at the bottom.
This half socket is then packed or cemented, and another pipe with its half socket at
the top-properly packed or cemented-is laid on to the end of the last pipe, the
flanges a a of each pipe fitting within the respective grooves a¹ a' of the pipes.
By this construction reliable joints can be easily and readily made and packed.
Figures 6 and 7. show a modification in which the flanges a and grooves a¹ are
dispensed with, the pipes being kept in place and locked the one to the other, by
interlocking pieces a³ a² formed on the ends of the half sockets A¹ as illustrated.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
1st. The improved construction of joint for sanitary, drain, and other pipes, as
hereinbefore described and illustrated by the accompanying drawing.
2nd. In a joint for sanitary, drain, and other pipes, the combination with the said
pipes, of the half sockets arranged on the ends of the pipes in the diametrically
opposite positions, the circumferential grooves therein, and the interlocking flanges,
all constructed, arranged, and operating, as and for the purpose set forth.
3rd. In a joint for sanitary, drain, and other pipes, the combination with the said
pipes of the half sockets arranged on the ends of the pipes in diametrically opposite
positions, and the interlocking pieces formed thereon, as and for the purpose set forth.
Dated this 24th day of January 1889.
