I, JOSEPH HAMBLET, of Piercy Blue Brick, Tile and Pipe Works, West Brom-
wich, in the County of Stafford, Blue Brick, Tile and Pipe Manufacturer, do
hereby declare the nature of this invention to be as follows:-
This invention has reference to sewer blocks which are made of clay and baked
like bricks and are usually of tubular form and laid end to end to form the base
or bottom of a sewer, the sides of the sewer being built on and springing from
the inclined sides of the sewer blocks which sides are sloped to the proper angles
and the top of the sewer block is made hollowed in a trough shape to form the
bottom of the interior of the sewer. The said sewer blocks are flat at the bottom
so as to lie evenly together. It is very important that the joints formed by the
meeting ends of the sewer blocks should be properly made so as to effectually
prevent the sewage leaking through these joints, as when such leakage occurs
and continues for some time the ground under the sewer becomes softened and
then the sewer at that part is liable to sink and crack. This invention is designed
so as to effectually prevent leakage where the sewer blocks join together.
In carrying out this invention each of the sewer blocks is rebated down at one
end thus forming a projecting spigot like part which is adapted to fit into the
open socket like end of the next sewer block and is made of a shape in cross
section corresponding with the cross sectional shape of the sewer block but
smaller. In the upper part of the sewer block and near to the other end of the
same I provide one two or more small holes which are immediately over the part
in which the spigot like end of the next sewer block fits.
Before laying the sewer blocks together two bands of suitable jointing material
are placed round the spigot like end of the sewer block one of these bands being
as near as possible to the end of the spigot part and the other jointing band close
to the rebated or shouldered part thus leaving a channel or space all round the
spigot like part between the two jointing bands. The spigot like part of the
sewer block is then inserted in the open end of the next sewer block so that the
shoulder or rebate of the one sewer block comes close to the end of the next and
then suitable cement is poured through one of the said holes in the socket like
end of the sewer block and this cement runs down and round between the two
jointing rings and the two sewer blocks and fills up this space thus making a
perfect joint. Air escapes through one of the said holes whilst the cement is
being poured in the other hole. I thus form a perfect joint and prevent any
leakage of the sewage between where the sewer blocks join together.

the end of the next sewer block A. and then suitable cement is poured through
one of the holes or 2 in the socket like end of the sewer block A and this
cement runs down and round between the spigot and socket and fills up the space
as shewn in Fig. 3 so as to make a perfect joint. Air escapes through the hole ba
whilst the cement is being poured down the other hole b¹. I thus form a perfect
joint and prevent any leakage of sewage where the blocks are joined together.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. Sewer blocks of the kind herein referred to, for forming the base or bottom
of a sewer, made substantially as herein before described and illustrated by the
accompanying drawings so as to joint together spigot and socket wise and thus
prevent any leakage through the joints and sinking of the base of the sewer, as
set forth.
2. A sewer block of the kind herein referred to, for forming the base or bottom
of a sewer, said sewer block having at one end a rebate a and spigot part a6 and
at the other end a socket part a adapted to receive the spigot end of the next
sewer block, the upper part of the socket end having holes such as 6162 through
which the cement can be poured into the socket when jointing the sewer blocks
together, substantially as set forth.
