Improvements in Junctions and Connections for Drainage Pipes.
I, PETER HUTSON, of the City of Wellington in New Zealand Pipe and Tile
Manufacturer, do hereby declare the nature of my invention for "Improvements
in junctions and connections for drainage pipes," 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 the method of putting in junction and connections in
earthenware drain pipes, and provides a means whereby in existing drains a
junction can be inserted and connections made which are perfectly tight and do not
damage the drain already laid down. The usual practice where it becomes
necessary to put in a junction in an existing drain is to break out a length of
piping and by raising each end of the pipes remaining to insert the length making
the junction. This necessitates forcing the sockets of the pipes over the spigot
end and prevents a perfectly tight joint being made.
My invention consists in an earthenware belted collar made in two sections, and
having a projection on one half fitting into a recess on the other as shown and of
a double spigot ended junction. One section of the collar is placed under the ends
of the pipes to be joined, the socket of the pipe already in position being taken off
and when properly cemented the other half of the collar is placed over the ends of
the pipes to be joined and is then cemented. It is not absolutely necessary in all
cases to make collar in two sections. A collar may be made which will fit the
pipes after the socket end of the pipe already in position is taken off and by
slipping up the pipes sufficiently far will allow the new junction to be inserted and
can then be slipped into position covering the ends to be joined equally, and can
then be cemented and made perfectly tight.

of piping, and B B B the sockets or collars ordinarily used.

the subject of my invention in position.

position, CC being the collar, G G G G the space for cementing the connections,
and E being projection fitting into recess F.
Fig. 4 shows a cross section of the collar as applied to the pipes in position,
CC being the collar, EE the projections fitting into recesses FF, A A the pipe
and G G the space for cementing the connections.
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. An earthenware belted collar made cither in two sections or in one entire
piece with a double spigot ended junction substantially as described and specified.
2. An earthenware belted collar in sections with the recess and projection as
shown and described.
