Improvements in and relating to Insertion Pipes and Joints for
Drains, Sewers, and the like.
HENRY JAMES WEAVER, C.E., Borough Engineer & Surveyor, of King's Lynn,
address Denmark House, Gaywood, King's Lynn, do hereby declare the nature
of this invention to be as follows:-
The insertion pipe is composed of ware glazed or unglazed, terra cotta or
iron and made in any size or capacity, and of two different lengths, the longest
of which may be a junction or plain pipe, the shortest length to have a deep
socket (with a slot in it) of sufficient depth to telescope the spigot end of the
junction or plain pipe, so as to easily insert it between the pipes already fixed,
then extend the inserted pipes leaving a space under the slot to receive a ring of
the same section to fill up that space, so that the inside surface of the inserted
pipes shall be smooth and even & without any obstruction throughout its whole
length. The joints to be made with cement, clay or other hard setting material:
The whole when put together to equal in length any pipe now made in terra-cotta
or iron; and which in my opinion there has not yet been the likes.

Improvements in and relating to Insertion Pipes and Joints for
Drains, Sewers, and the like.
I, HENRY JAMES WEAVER, C.E., Borough Engineer and Surveyor, of King's
Lynn, address Denmark House, Gaywood, King's Lynn, 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 pipes known in the sanitary business as insertion
junction pipes, and which are made of glazed or unglazed ware, terra cotta or
iron, and formed of any size or capacity.
I will now describe my invention with reference to the accompanying drawings,
in which:
Fig. 1 shews an elevation of a pipe constructed according to my invention and
showing the loose ring or 'making up piece" detached.
Fig. 2 shews a longitudinal section of Fig. 1 with the loose ring or "making up
piece in place.
Fig. 3 shows an outside elevation of the pipe complete with sealed joints.
The insertion pipe or junction consists of three different parts, the longer a of

which may be a junction or plain pipe and the other or shorter 6 has a deep socket
with an opening c in it to receive the ring or making up piece" d. The
elongated socket is of sufficient depth to telescope the spigot end of the junction
or plain pipe a, so as to enable the entire length, that is lengths a and b together,
to be easily inserted between two ordinary pipes already laid down or fixed. When
thus inserted the longer part a is extended to engage with the adjoining pipe
and the spigot end of the socket 6 is inserted into the other adjoining pipe in a
manner as to leave a space under the slot c to receive the ring d to fill up the
space, said ring & being of similar section as the body of pipe a, so that the inside
surface of the inserted pipes shall be smooth and even, and without obstruction.
throughout their whole length. The joints are then sealed with cement a, or
clay or other hard setting material. The whole, that is parts a b and d, when put
together, may equal in length any ordinary pipe now made in terra cotta, iron or
other material.
I would explain that in my insertion pipe, which as before stated, may be
made as a plain pipe or with a junction or junctions attached, the objectionable
split" or "half collar" now used is avoided. The whole space between the
inside of the elongated socket 6 and the "making up piece" or ring d which is
dropped into the elongated socket, can readily and with certainty be completely
filled with jointing cement and an absolutely watertight joint can be made
without difficulty, which may be finished on the outside by completely covering
the top of the "making up piece" or ring d with cement flush with the outside
of the elongated socket or by a fillet of cement as shewn at a.
A perfectly true invert may be obtained by projections e being made on the
elongated socket on which the spigot of pipe a rests. The "making up piece" or
ring & may also be provided with a projection f centrally half round its circum-
ference on which it can rest on the socket.
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) In a main pipe for sewage or other purposes, the elongated socket pipe b
having an opening such as c, as herein described and set forth..
2) In a main pipe for sewage or other purposes, the elongated socket pipe b
having a slot e to receive a ring or making up piece" such as d, as herein
described and shewn.
3) The combination of the pipe a with the elongated socket pipe b, the slot e
and the ring or "making up piece" d and the mode of fixing same together with
cement or the like, as herein described and set forth.
Dated this 10th day of March 1900.
