PROVISIONAL SPECIFICATION.
An Improved Joint or Coupling for Earthenware Pipes.
We, WILLIAM OATES and JOHN JOHNSTON GREEN, of the Firm of Oates &
Green, Limited, Claremount, Halifax, in the County of York, Sanitary Engineers,
do hereby declare the nature of this invention to be as follows:-
This invention relates to a new form of joint or coupling for earthenware pipes.
According to one form of our invention the socket is provided with two small
holes in which to pour cement. The inside of the socket is made with a bevil edge
and a corresponding bevil edge on the spigot leaving a space between to be filled
up with cement.
According to another form, the bevilled part is dispensed with and a horizontal
aperture formed, whilst a third method consists in having two recesses in the end
of the spigot, an incline being formed between the two recesses. The cement is
poured through the holes into these recesses and in all the three methods double
joints are formed.

COMPLETE SPECIFICATION.
An Improved Joint or Coupling for Earthenware Pipes.
We, WILLIAM OATES and JOHN JOHNSTON GREEN, of the Firm of Oates &
Green, Limited, 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:-
This invention relates to a new form of joint or coupling for earthenware pipes.
In order that our invention may be clearly understood we will make reference
to the accompanying sheet of drawings, wherein Fig. 1 is a longitudinal section of
an earthenware pipe used for drainage purposes, and Fig. 2 a cross section through
line A, B, in Fig. 1.
According to our invention we form a bevelled part C in the socket end of the
pipe, and a corresponding bevelled part D at the outer end of the said pipe; and
there also formed indents or recesses to receive clay or packing E. At one portion
of the socket end of the pipe we form a projection F for the end of an adjoining
pipe to rest upon. The projection F is preferably made bevelled on its innerside
as shewn at G so that a space H is left to allow the cement or other material to
find its way around the pipe. There is also an annular space left at I which is
filled with liquid cement through the aperture or opening J. The joint of the pipe
is made increasingly secure by a ring of clay or cement L.
By joining pipes in the manner shewn herein they are made perfectly watertight,
and by the use of the projection F the inner end of the pipe cannot sink and break
the joining as is now commonly done.

page_text: 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 :-
Firstly. The formation of the bevelled parts C, D, together with the recess for
the reception of clay or packing E in earthenware pipes.
Secondly. Earthenware pipes formed with the projection F employed in the
manner and for the purposes described.
Thirdly. In earthenware pipes the formation of the recess for the reception of
cement all as described.
