improved means for Connecting Sanitary ripes.
I; JOHN EDWIN PLACE, of Long Marsh, Darwen, in the County of Lancaster,
Sanitary Pipe Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to socketted sanitary pipes, the object of the invention being
to ensure good joints and a true invert and to facilitate repairs of the drain formed
by my improved pipes.
The invention consists in forming in the socket of each pipe and in the lower part
thereof a semicircular seating of such shape as to form a locking bed for the spigot
end of the next pipe, the said spigot end being provided with a corresponding
semi-annular projection.
When joining two pipes together the spigot end of one pipe is slightly raised from
the level of the socket of the next pipe and pushed thereinto and then lowered so that
its semiannular projection beds into and is locked by the semi-circular seating in the
socket.
The seating and semi-annular projection are or may be applied to the pipe in
the manner usual in the formation of what is known as the "Stamford" joint.
The semi-circular seating of the pipe may be inclined or curved downwards and
inwards to draw the spigot end of the next pipe into its socket.
When the pipes are coupled together the space between the upper or plain
part of the socket and the plain part of the spigot may be filled in with cement
or the like. If the seating of the socket is curved it will allow of a slight
inclination of the next pipe if required, I may make the pipes with only half a socket
to contain the semicircular seating leaving a flange at the upper half of the pipe
against which the spigot end of the next pipe abuts and the joint in this case may be
made good say by filling in the angle formed by the flange and spigot end with
cement or other suitable material.

I, JOHN EDWIN PLACE, of Long Marsh, Darwen, in the County of Lancaster,
Sanitary Pipe Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
5 ascertained in and by the following statement :-
This invention relates to socketted sanitary pipes, the object of the invention

page_text: being to ensure good joints and a true invert and to facilitate repairs of the drain
formed by my improved pipes.
The invention will be clearly understood from the following description on reference
to the accompanying sheet of drawings on which
Fig. 1 shews the spigot end of one pipe near the socket end of another pipe (the
latter in section) and ready to be fitted together.
Fig. 2 shews a transverse section through the spigot end and a face view of the
socket.
Fig. 3 shews the two parts connected and cemented together.
Figs. 1 and 2 show modified forms of the joint.
Fig. 4 is a face view, and Fig. 5 a section shewing a further modification hereafter
more particularly referred to.
The invention consists in forming in the socket of each pipe seen at a on the
drawings and in the lower part thereof a semicircular seating such as a¹ of such
shape (see Figs. 1, 1A, 2A and 5) as to form a locking bed for the spigot end of the
next pipe shewn at 6 on the drawings, the said spigot end being provided with a
corresponding semi-annular projection such as b¹.
When joining two pipes together the spigot end of one pipe is slightly raised
from the level of the socket of the next pipe and pushed thereinto as seen by dotted
lines on Fig. 3, and then lowered so that its semi-annular projection 6¹ beds into and
is locked by the semicircular seating a¹ in the socket a as shewn by the full lines on
that fig.
The seating a¹ and semi-annular projection b¹ are or may be applied to the pipe
as illustrated in the manner usual in the formation of what is known as the
"Stamford" joint.
The semi-circular seating a¹ of the pipe may be inclined or curved downwards and
inwards as seen at Figs. 5A and 2^ to draw the spigot end of the next pipe (which is
correspondingly inclined or curved) into its socket.
When the pipes a and b are coupled together the space seen at c (Figs. 2 and 3)
between the upper or plain part of the socket and the plain part of the spigot may
be filled in with cement clay or other suitable material. If the seating a¹ of the
socket a is curved as seen at Fig. 1 it will allow of a slight inclination of the next
pipe if required.
may make the pipes with only half a socket a¹ (as seen at Figs. 4 and 5) to
contain the semi-circular seating b' leaving a flange a* at the upper half of the
pipe against which the spigot end of the next pipe abuts, and the joint in this case
may be made good say by filling in the angle cx formed by the flange a* and spigot
end with cement or other suitable material, as shewn by the dotted lines on
Fig. 5.
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 :-
The improved means for connecting sanitary pipes consisting in forming in the
socket end of each pipe and in the lower part thereof a semicircular seating of such
shape as to form a locking bed for the spigot end of the next pipe, the said spigot
end being provided with a corresponding semi-annular projection, substantially as
herein before described.
