PROVISIONAL SPECIFICATION.
Improvements in Jointing Stoneware or Earthenware Sewerage
Pipes.
I, FREDERICK HENRY BROOK of 171 Queen Victoria Street in the City of
London, Brick and Tile Merchaut do hereby declare the nature of this invention to
be as follows:-
This invention relates to sewerage pipes and has reference more particularly to
the making of the joints, at the time the pipes are laid, by means of cement being
run into the annular space or spaces between socket & spigot, by or through holes
in the socket commonly called "grouting holes."
The object of this invention is to ensure a more complete ring or layer of
cement being formed and to allow of a stiffer grout or liquid cement being used if,
preferred.
In carrying out my invention I form the sockets of the pipes with a hole or
holes at or below the side of the socket, instead of at the top only, and I may also
have one or more holes intermediate between that which is lowest, (or nearest the
bottom) and the top, where there will also be one or more holes.
When the pipes are in position for the sealing of the joints I proceed to introduce
the cement grouting or other suitable fluid cement, into or through the lowest hole,
till that segment of the annular space is full up to that hole or the hole or holes
next above it. I then so plug or close the hole as to prevent leakage of the cement
when poured in, but not to prevent air escaping, and, if there are any more holes
between that & the top I continue to fill from the next hole above, completing the
grouting operation through the topmost hole after similarly filling at and up to the
other intermediate holes, (if any) and those on the other side.
Or 1 may fill from the lowermost hole or any intermediate hole by means of a
feeder or funnel or tube or equivalent device the open outer end of which may be
as high or higher than the top of the socket as a kind of spout by which means the
liquid cement will rise around the annular space to the top, escape of the air being
provided for and taking place through the topmost hole or through the lower holes
also, till they are plugged or filled up as and when the cement rises up to them.

Improvements in Jointing Stoneware or Earthenware Sewerage
Pipes.
I, FREDERICK HENRY BROOK of 171 Queen Victoria Street in the City of
London, Brick and Tile Merchant, 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 improvements in or connected with sewerage pipes and
has reference more particularly to the making of the joints at the time the pipes are

page_text: laid, by means of cement being run into the annular space or spaces between socket
and spigot by or through holes in the socket commonly called "grouting holes."
The object of this invention is to ensure a more complete ring or layer of
cement being formed and to allow of a stiffer grout, or liquid cement, being used,
if preferred.
I will now proceed to describe my invention by the aid of the accompanying
drawings.
Fig. 1 is a view of the socket end of a drain pipe constructed in accordance
with my invention.
Fig. 2 is a sectional view of socket of one pipe and spigott of another placed
therein.
Similar parts being similarly lettered throughout.
In carrying out my invention I form in any suitable manner the sockets with one
or more holes in addition to and below those at the top, commonly or usually
made and shewn at B, B' in Figs. 1 & 2.
In Figs. 1 & 2 two additional holes, A, A' are shewn & this is the number I
usually prefer, but in the larger diameters of pipes I may have other holes around
the socket, varying in number according to the size of the pipe and the degree of
fluidity of the cement employed to make the joint.
When the pipes are in position for the sealing of the joints I proceed to
introduce the ceinent grouting or other suitable fluid cement, into or through one
of the lowest holes till that segment of the annular space between the feeding hole
and the corresponding hole on the opposite side is filled with cement.
In cases
where a spout or funnel C is used for pouring in the cement, I may continue
feeding until the cement rises above feeding hole A to any desired extent. I then
so plug or close the hole in any suitable way as to prevent leakage of cement, but
not to prevent air escaping, and I complete the grouting operation through the
topmost hole after similarly filling at and up to the other intermediate holes (if any)
and those on the opposite side.
Or I may fill from the lowermost hole or any intermediate hole, by means of a
feeder or funnel or tube or equivalent device, the open outer end of which may be
as high or higher than the top of the socket as a kind of spout, as shewn in Fig. 2
at C. By this means the liquid cement will rise around the annular space to the
top, escape of air being provided for, and taking place through the topmost hole, or
through the lower holes also, till they are plugged or filled up, as and when the
cement rises up to them.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In sewerage or drain pipes the perforating of the sockets at one or two or
more points, in addition to the topmost part of the sockets substantially as and
for the purpose hereinbefore described and as illustrated by the accompanying
drawings.
2. In sewerage or drain pipes the methods of making or sealing the joints
substantially as and for the purpose hereinbefore described.
