I, JOHN MORGAN, of Pontardawe, R.S.O., Swansea, in the County of Glamorgan-
shire, Inventor, do hereby declare the nature of this invention to be as follows;-
My invention relates to improvements in stoneware drain pipes which is con-
structed as follows:-
Inside the socket and on the shoulder of the pipe a projection is formed with
a slight taper outward from the shoulder to its point. The length of said pro-
jection to correspond with the length from the spigot end to the collar. A groove
is made in the face of the projection.
A small hole is made in the socket midway between the said projection and the
socket end.
I form a collar on the pipe, at
with the length of the projection.
or grooved. The collar must not
being placed inside the socket.
a distance from the spigot end to correspond
The face of the said collar to be corrugated
be raised above the pipe to prevent it from
I form another collar at a point on the pipe so that its face will nearly come
in contact with the end of the socket when the spigot end of the pipe is pushed
home. This collar is to have its face corrugated, and it is to be raised above the
surface of the pipe, so as to be about a quarter of an inch more in diameter than
the inner side of the socket.
MODE OF MAKING THE JOINT.
A fillet of plastic clay or cement is laid on the spigot end and against the one
collar and a similar fillet is also laid against the face of the other collar.
The spigot end of pipe is then inserted in the socket and pushed home, when
the plastic fillet of clay or cement on the end will be pressed into the groove
and around the projection making it water-tight.
Similarly the fillet of clay or cement placed around the pipe and against the
face of collar, will, when the pipe is pressed home into the socket, fill up the
space between it and the inner side of the socket, and the space between the face
of the collar and the end of the socket, thus rendering the outer end of socket
water-tight. The space left between the fillets of clay or cement is then to be
filled with neat Portland cement grout, through hole in crown of socket.

in and by the following statement: --
My invention relates to improvements in stoneware drain pipes which is con-
structed as follows:-
:
And in order that my invention may be thoroughly understood, I now proceed 5
to describe the accompanying drawing thereof, reference being had to letters and
figures marked thereon.
Inside the socket a¹ and on the shoulder of the pipe f a projection a is formed
with a slight taper outward from the shoulder to its point. The length of said
projection to correspond with the length from the spigot end to the collar d. 1
A groove is made in the face of the projection.
The depth from the invert of the pipe to the commencement of the projection a
is to correspond with the thickness of the metal in the spigot end, so as to form
a true invert when making the joint and the diameter of the opening at the
butt end of the projection is to be slightly larger than that of the spigot end, 1
including the thickness of the metal, that is to say; the spigot, when resting on
the invert of the projection «, will have a clear space between it and the sides
and soffit of the said projection.
A small hole c is made in the crown of the socket midway between the said
projection and the socket end.
I form a collar d on the pipe, at a dist. ce from the spigot end g to correspond
with the length of the projection a. The face of the said collar to be corrugated,
or grooved. The collar must not be raised above the pipe to prevent it from
being placed inside the socket.
MODE OF MAKING THE JOINT:-
A fillet of plastic clay h or cement, is laid on the spigot end and against the
collar d. The spigot end of pipe is then inserted in the socket and pushed home;
when the plastic fillet of clay or cement on the end will be pressed into the
groove and around the projection a, making it water-tight; the whole forming a
true invert.
A fillet of clay or cement is also laid at the end of the socket, thus rendering
the outer end water-tight. The space left between the fillets of clay or cement
is then to be filled with neat Portland cement j grout, through the hole or holes o
in crown of socket.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is
1. The drain pipe substantially as fully above described in this specification
and illustrated on the accompanying drawing.
2. in a drain pipe, the combination and arrangement of the collar d, grooves
clay or cement fillets and i, with filling grouted in with Portland cement j,
substantially as herein described and according to the accompanying drawing.
3. In the flange of a drain pipe, the projection u with a groove b formed inside
the socket a¹, substantially as herein described and according to the accompanying
drawing.
