PROVISIONAL SPECIFICATION.
An Improved Means or Method of Forming the Joints in
Earthenware Pipes.
We JOHN JOHNSTON GREEN and WILLIAM OATES of the Firm of Oates and
Green Limited of Claremount, Halifax in the County of York, Sanitary Engineers
do hereby declare the nature of this invention to be as follows :-
In constructing our improved joint for pipes we form in the socket end of the
pipe a shoulder or inner socket going all around the said socket and into this inner
socket we insert the spigot end of an adjoining pipe the arrangement being such
that the inner surfaces of the two pipes are lineable or level. We also form
a joint made of Stanford's or other suitable composition, consisting of two rings
the outer edges of which are flush with the outer edge of the socket but in
accordance with our invention an annular space is left between the inner edges
of the two rings and the outer edge of the additional inner socket and into this
space we pour cement, a suitable form of opening or aperture being made in the
socket end of the pipe in which to pour the said cement.
This form of joint
which comprises three features viz., the additional shoulder or socket, the Stanford
or other suitable form of joint, and the annular space for receiving cement, forms
a new combination and will be found very effective in practical use.

An Improved Means or Method of Forming the Joints in
Earthenware Pipes.
We, JOHN JOHNSTON GREEN and WILLIAM OATES, of the Firm of Oates and
Green, Limited, of Claremount Halifax in the County of York, Sanitary Engineers,
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 :-
Our invention refers to prior Letters Patent granted to us on the 24th day of
November, A.D. 1894 No. 22,773.
In order that our present invention may be more clearly understood, we will
make reference to the accompanying sheet of drawings illustrative thereof.
In constructing our improved joint for pipes, we form in the socket end of the
pipe A a shoulder or inner socket B arranged to be all around the said socket and
into this inner socket B we insert the spigot end of an adjoining pipe C the arrange-
ment being such that the inner surfaces of the two pipes are lineable or level as
shewn at D. We also form a joint consisting of rings E and F made of Stanford's
or other suitable composition the outer edges of the two rings being made flush or
level with the outer edge of the socket A but in accordance with our present
invention an annular space G is left between the inner edges of the two rings E

page_text: and F and the outer edge of the additional inner socket B and into this space G
we pour cement through the aperture H. This form of joint which comprises
three features namely:-The additional shoulder or socket B the Stanford or other
suitable joint E, F, and the annular space G for receiving cement forms a new
combination and will be found very effective in practical use.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
The means or method of forming the joints in earthenware pipes by the
combination of the additional shoulder B with a Stanford or other suitable
joint E, F, and annular space G for receiving cement, arranged and combined
substantially as illustrated in the drawings.
