PROVISIONAL SPECIFICATION.
Improvements in Jointing Earthenware or Stoneware 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 ordinary straight earthenware or stoneware
sewerage pipes.
In carrying out my invention, I employ a short collar or ring of earthenware or
stoneware, the internal diameter of the ends being larger than the internal diameter
of the central part, which corresponds with the external diameter of the pipes to
be joined. The outer part of the collar or ring may be cylindrical or recessed.
The ends of the pipes are placed in the central part of the collar and caused to
abut, whereupon the annular spaces between the ends of the collar or ring and the
abutting pipes are filled with cement; a perfectly secure joint resulting.
The collar or ring may be made in a press or in a divided mould.

COMPLETE SPECIFICATION.
Improvements in Jointing Earthenware or Stoneware 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 ordinary straight earthenware or stoneware
Bewerage pipes.
In the accompanying drawings,
Fig. 1 represents in vertical section on the line x, x (Fig. 3) two ordinary
straight sewerage pipes jointed according to my improved method.
Fig. 2 is a corresponding side elevation.
Fig. 3 is a cross section on the line y, y (Fig. 2).
Fig. 4 is an end elevation of the collar or ring employed in making the joint.
Figs. 5 and 6 show a collar or ring of slightly different shape.
In carrying out my invention, I employ a short collar or ring A. A' A' of
earthenware or stoneware, the internal diameter of the ends A being larger than
the internal diameter of the central part A' A³, which corresponds with the
diameter of the pipes B to be joined. The outer part of the collar or ring A A'A'
may be cylindrical, as in Figs. 1 and 2, or recessed, as in Figs. 5 and 6.
The ends
of the pipes B are placed in the central part A' A' of the collar or ring, against
which they are caused to abut, whereupon the annular spaces between the ends A
filled with cement or
of the collar or ring and the abutting pipes B are
composition C; a perfectly secure joint resulting.
The collar or ring A A' A² may be made in a press or in a divided mould.

page_text: I am aware that sewerage pipes have already been joined by placing their ends
in short pipes or unions of larger diameter, such short pipes or unions having ends
unadapted for the reception of the ordinary jointing material, I therefore make no
claim to short pipes or unions of the kind above referred to, but
Having particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I do
claim is :-
1. In jointing ordinary straight earthenware or stoneware sewerage pipes, the
employment of a collar or ring of earthenware or stoneware having the ends of con-
siderably larger internal diameter than the central part, which corresponds with the
diameter of the pipes to be joined, the annular spaces between the ends of the collar
or ring and the pipes being filled with ordinary cement or jointing material,
substantially as herein described.
2. The improved earthenware or stoneware collar or ring for use in jointing
ordinary straight earthenware or stoneware sewerage pipes substantially as shown
in the accompanying drawings.
Dated the 28th day of March 1894.
