page_text: An Improved Sliding Socket Drain Pipe.
HORACE WILLIAM SWAIN, Rock House, Stapleton Road, Bristol, Jeweller and
Tailor, do hereby declare the nature of this invention to be as follows:-
A pipe made of iron or clay with a flange, and a loose or sliding socket.
On the one end of the pipe there is a flange about three quarters of an inch
deep, on the edge of the flange, and equally arranged there are two or more
raised portions of clay or iron about half an inch long and a quarter of an inch
thick called keys; along this pipe a socket about three inches deep is meant
to slide and to be fixed close up to the flange.
On the inside of the socket there are two or more grooves made with a right-
angle return, the number of grooves in the socket corresponding to the number of
keys on the edge of the flange. As the-socket is slid along the pipe to the flange,
the grooves in the socket are brought opposite to the keys on the edge of the
flange, and then by passing the keys down the grooves and turning the socket, the
keys pass into the right-angle returns in the socket, and so become locked, thus
preventing the socket from slipping back or getting out of place whilst the joint
is being made.
Dated this 31st day of May 1898.
An improved Sliding Socket Drain Pipe.
HORACE WILLIAM SWAIN, Rock House, Stapleton Road, Bristol, Jeweller and
and Fancy Dealer, 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 consists of an improvement on drain pipes with fixed sockets.
The pipe herein referred to has a flange, key-pieces, and a loose socket with key-
ways to suit the key-pieces on the barrel of the pipe.
The accompanying drawings shew the nature of my invention and on reference
to them it will be seen that Figure 1 shews a plan of the flange a at the end of the
barrel of the pipe, and the key-pieces 6 which are moulded or cast on the barrel
of the pipe at a distance required at the back of the flange a.
Figure 2 shews the pipe with the loose socket c in position.
Figure 3, shews a plan of the loose socket c, the back portion of which is
D

page_text: flanged downwards, with key-ways cast or moulded in the flanged portion to suit
the position of the key-pieces b on the barrel of the pipe on Fig. 1.
This pipe instead of having a socket end will have a flanged end as shown by a
on Figure 1; at a distance behind the flange a, "which would be determined by the
thickness of the flanged portion of the loose socket c, Figure 3," there will be key-
pieces cast or moulded to the barrel of the pipe as shown by on Figure 1. Along
the barrel of the pipe the loose socket c Fig. 3, of sufficient diameter at one end
to cover the flange a on Figure 1 will pass, the other end of the loose socket c on
Figure 3 will be flanged downwards so that it will pass over the barrel of the
pipe only but not over the flange. In the flanged end of this socket there will be
key-ways cast or moulded as shown by letter on Figure 3. These key-ways will
be made in a corresponding position to the key-pieces b on Figure 1.
When the pipe is inserted in its position the loose socket c, with the key-ways d,
will be slid along the barrel of the pipe the key-ways d passing over the key-
pieces b, until the socket c, is close up to the back of the flange a.
The socket
can then be turned either to the right or the left hand until a solid portion of the
socket c, is brought to bear against the key-pieces b, in this way it will thus become
locked, and so prevented from moving backwards whilst the joint is being made.
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 key-pieces on Figure 1.
