PROVISIONAL SPECIFICATION.
Improvements in or relating to the Construction of Sewers.
I, THOMAS HENRY VERCOE, of 14 Walham Grove, Fulham, London, S.W.,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of the present invention is to economise material and labour in the
construction of sewers; further, sewers constructed in accordance with my invention
as hereinafter described, will not be liable to percolation by sewage, as frequently
happens in brick built sewers.
According to my invention, I propose to substitute for the usual brick built
sewer, a sewer constructed in sections, each section being built up of segmental
lengths of glazed stoneware, the meeting edges of which are so shaped as to fit into
one another and form with the aid of cement fluid tight joints. The ends of the said
segmental lengths are also so shaped as to produce on the end of the section built
up therefrom a socket or annular groove for making a joint with the adjacent
section.
The sewer thus constructed will be enclosed in concrete in the usual manner.
My invention may also be substituted with economical advantage for the larger
sizes of glazed stoneware pipes.

I, THOMAS HENRY VERCOE, of 14 Walham Grove, Fulham, London, S.W.,
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:-
The object of the present invention is to economise material and labour in the
construction of sewers; further, sewers constructed in accordance with
my invention,
as hereinafter described, will not be liable to percolation by sewage, as frequently
happens in brick built sewers.
According to my invention, I propose to substitute for the usual brick built
sewer, a sewer constructed in sections, each section being built up from segmental
lengths of glazed stoneware or analogous non-porous material, the meeting edges
of which are so shaped as to fit into one another and form, with the aid of cement,
fluid tight joints. The ends of the said segmental lengths are also so shaped
that the ends of the segmental lengths composing one section will fit into the ends
of those composing the adjacent section, the joints being made fluid tight by
cement.
The usual centres will be employed in building up the sewer sections, and the
sewer will be enclosed in concrete in the ordinary manner.

My invention may also be substituted with economical advantage for the larger
sizes of glazed stoneware pipes.
In the accompanying drawings in which similar letters refer to corresponding
parts in all the figures:-
Fig. 1 is a transverse section and. Fig. 2 is a side elevation of one section of a
sewer constructed according to my invention.
Fig. 3 is an end view of Fig. 2 looking from the right.
Fig. 4 is a transverse section shewing a modified form of joint for connecting the
edges of the segmental lengths, and
Fig. 5 is an elevation on a reduced scale shewing the connection between two
sections of the sewer.
The
Each section A, which may be of any convenient length, is built up from the
segmental lengths a of glazed stoneware or analogous non-porous material, the
meeting edges of 'the said segmental lengths being so shaped as to fit into one
another as shewn at b, the joints being made. fluid tight by means of cement.
bottom segmental length is preferably formed with a flat base a¹. On the end of
each segmental length there is provided or formed a flange e whereby a joint, made
fluid tight by cement, is formed with the corresponding segmental length of the
adjacent section. I prefer that the segmental lengths a should be arranged as
shewn in the drawings, i.e. so that their ends break joint with one another, this
arrangement considerably strengthening the sewer. Any convenient number of
segmental lengths a may be employed for each section A, the number depending
principally upon the sectional area of the sewer; in the case of very small sewers,
each section might be built up from two segmental lengths only.
Provision for house connections may of course be made in the segmental lengths
when necessary.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
1. A sewer constructed in sections, each section being built up from segmental
lengths of glazed stoneware or analogous non-porous material the meeting edges of
which are so shaped as to fit into one another and form with the aid of cement
fluid tight joints, substantially as described and illustrated.
2. A sewer constructed substantially as illustrated in the annexed drawings.
