Improved Joint for Drain Pipes and the like.
I THOMAS WILLIAM YARDLEY Architect of Weston Street Swadlincote
Burton-on-Trent in the County of Derby do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in and relating to pipe joints and is
designed to provide for the connection of lengths of sewer pipes of stoneware or
earthenware or the like, by means of tongue and groved socket to prevent leakeage
and is much easier to fix also, the pipes can be removed or taken out without
breaking them.
The socket portion of my pipes is made with a loose or removable piece which
is arranged to be on the top side of the socket when they are being laid. A groove
runs round the inside of the socket and also around the under side of the loose
peice and the top part of the Bocket is cut away so that the spigot end of the pipo
with its head or enlargement may be lowered vertically into the socket and thus
any length of piping may be so laid one length after the other by lowering them
vertically and without moving them end wise into the sockets which is now the
custom.

Improved Joint for Drain Pipes and the like.
I, THOMAS WILLIAM YARDLEY, Architect, of Weston Street, Swadlincote,
near Burton-on-Trent, in the County of Derby, do hereby declare the nature of
my said 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 has for its object improvements in pipes which I call tongued and
grooved pipes and has particular reference to the formation of the socket end of
pipes which offers great facility for joining the lengths together and for making
the joints and for examination and repairs.
In explaining my invention I will refer to the accompanying sheet of drawings
which will enable ine to make the parts better understood and by the help of
which others will be able to adapt the invention to the various circumstances
met with in practise.
Figure 1 shows the exterior view two pipes A and A' joined together according
to my invention and the left or socket end at of the pipe A is ready to receive the
next length of pipe.
Figure 2 is a broken off section through the jointed part of the pipes A and A¹.

page_text: Figure 3 shows a modification of the formation of the socket a and spigot a².
Figure 4 is a view of the socket end a' of one of the pipes with the loose piece a
lifted out of its position.
Figure 5 is a view of the under side of the loose piece a*.
The socket portion of my pipes is made with a loose or removable piece a' which
is arranged to be on the top side of the socket when they are being laid. A
groove a runs round the inside of the socket and also round the under side of the
loose piece a as shown at Figure 5 and the top part of the socket is cut away
at a as seen in the end view Figure 4 so that the spigot end of the pipe with its
bend or enlargement a may be lowered vertically into the socket and thus any
length of piping may be so laid one length after the other by lowering them
vertically and without moving them end wise into the sockets which is now the
custom. The groove as may be made as large as is desired so as to receive a
quantity of plastic cement, clay or other sealing material after which the loose
piece a may be lowered into its position and also sealed with cement or other
plastic material. This loose piece a' may be removed at any time to examine tho
joint and the joint can be examined before it is placed in position. The formation
of the socket may be varied to suit the material whether earthenware or composition
or metal but the shapes given in section at Figures 2 and 3 will generally be found
sufficient though I do not limit myself to them and the lip a niay be made
much less if desired.
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 :-
The improvements in pipes consisting essentially of a socket having an opuning
at the top so that the spigot end of the next pipe may be lowered vertically into
its position and there locked by the bend a and lip a with the covering piece
to seal the joint, all substantially as horein set forth and as shewn upon the
accompanying drawings.
