PROVISIONAL SPECIFICATION.
Improvements in Jointing Earthenware Sewerage Pipes.
I, FRANK SARGENT MAYO, of 22, Boscombe Road, Uxbridge Road, in the
County of Middlesex, Sanitary Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to jointing earthenware or stoneware sewerage pipes; its
objects being, first, to guard against leakage of liquid from the sewer, secondly,
to ensure that the axes of the pipes, even when the pipes are laid by an unskilful
workınan, shall form a continuous line, thirdly, to provide an unyielding joint, and,
fourthly, to effect economy in the manufacture.
In carrying out this invention, a flange is formed on each end of the pipe. The
lower parts of the flanges of two adjacent pipes are laid in a trough, a cover being
placed over the upper parts of the flanges. The cover contains two holes side by
side. Liquid cement is poured into one hole; the confined air escaping through
the other. When the cement becomes set, the pipes, trough and cover are held
firmly together; the joint being fluid-tight.
The flanges and the edges of the trough and of the cover may be roughened,
bevelled or recessed for strengthening the joint. Other parts of the same may be
Hlared or hollowed out for the reception of plastic clay to prevent the escape of the
cement while in the liquid state.
The cover may, in certain cases,
may be substituted for the flanges.

COMPLETE SPECIFICATION.
Improvements in Jointing Earthenware Sewerage Pipes.
I, FRANK SARGENT MAYO, of 22, Boscombe Road, Uxbridge Road, in the
County of Middlesex, Sanitary Engineer, 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 jointing earthenware or stoneware sewerage pipes; its
objects being, first, to guard against leakage of liquid from the sewer, secondly, to
ensure that the axes of the pipes, even when the pipes are laid by an unskilful
workman, shall form a continuous line, thirdly, to provide an unyielding joint, and,
fourthly, to effect economy in the manufacture.
The accompanying diagram shows two joints made in accordance with my
invention; one joint being in section and the other in side elevation.
In carrying out this invention, a flange, such as a, is formed on each end of the
pipe A. One of these flanges may be a composition band. The lower parts of the
flanges of two adjacent pipes are laid in a trough B, a cover C being placed over
the upper parts of the flanges. The cover may contain two holes side by side, and
liquid cement may be poured into one hole; air escaping through the other.
Or the cement may be applied with a trowel. When the cement D becomes
set, the pipes A, trough B and cover C are held firmly together; the joint being
fluid-tight.
The flanges of the pipes and the edges of the trough B and of the cover C may
be roughened, bevelled or recessed for strengthening the joint. Other parts of the
same may be flared or hollowed out for the reception of plastic clay, or the parts

page_text: may be dipped in composition, to prevent the escape of the cement while in the
liquid or plastic state.
The cover may, in certain cases, be dispensed with, and projections on the pipe
may be substituted for the flanges.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I would have it understood
that I am aware a straight pipe with a band of composition on each end has been
claimed before, and that a joint comprising two rings of cement has also been
claimed, I do not therefore claim either of these features, but what I do claim is :-
1. The improved method of jointing sewerage pipes substantially as herein
described.
2. Enclosing the flanged ends of two adjacent sewerage pipes by a trough and
cover, and filling in the space between the parts with cement, substantially as herein
described.
3. A pipe-joint comprising a trough and a cover substantially as herein described
with reference to the accompanying diagram.
