PROVISIONAL SPECIFICATION.
Improvements in Earthenware Pipes and the Means of Connecting
the same.
I, TOM STREET, Clerk of Works, of 292, Kilburn Lane, West Kilburn, in the
County of London, do hereby declare the nature of this invention to be as
follows:-
―:
My invention relates to improvements in earthenware pipes and the means of
connecting the same, and consists of bevelled rings formed in the inside of the
flange with a key to connect the rings together; and at the spigot end of the said
pipe on its periphery I construct corresponding bevelled rings and key, for the.
purpose of these said rings fitting the rings in the inside of the flange when the
pipes are being connected together. On the outside of the flange holes are made
of any suitable shape which appear uppermost as the pipes are laid in their bed,
and into these holes I pour Portland or any other cement, which runs around the
spigot end of the pipe, and the flange between the rings, to fix or connect the pipes
together.
The object of the keys which are placed between the holes in the inside of the
flange and the top side of the spigot, is to ensure the cement passing around the
pipe and flange, and to make a good and solid joint.
A groove is formed at the shoulder in the inside of the flange, for the purpose
of making a clay joint before the cement joint is formed.
The rings and keys may be constructed in earthenware, Portland cement, or any
other suitable material.

COMPLETE SPECIFICATION.
Improvements in Earthenware Pipes and the Means of Connecting
the same.
1, TOM STREET, Clerk of Works, of 292, Kilburn Lane, West Kilburn, in the
County of London, 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 :-
My invention relates to improvements in earthenware pipes and the means of
connecting the same, and consists of bevelled rings formed in the inside of the
flange with a key to connect the rings together; and at the spigot end of the
said pipe on its periphery I construct corresponding bevelled rings and key for
the purpose of these said rings fitting the rings in the inside of the flange when
the pipes are being connected together. On the outside of the flange holes are
made of any suitable shape which appear uppermost as the pipes are laid in their
bed, and into these holes I pour Portland or any other cement, in a liquid state,
which runs around the spigot end of the pipe, and the flange, between the rings, to
fix or connect the pipes together.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Figure 1 represents an elevation of the pipe d and the flange e, with a spigot
end fitted into the flange e, and is illustrated by dotted lines, and by a part of the

page_text: figure broken off in order to show the said part in section. At the spigot end 1
form the rings c, and b, and connect these rings together by the key a. In the
interior of the flange e, I construct a bevelled ring to correspond with the ring b
and a ring to correspond with the ring e, so that they fit into each other; the
cement is then poured into the holes so as to fill up the whole of the cavity i
around the pipe and inside the flange. Figure 2 is the inside of the flange e under
the holes h, to describe the key a¹ to connect the rings and together. The
key is fitted above the corresponding key a when the pipes are connected
together.
The object of the keys a, and a', which are placed between the holes in the
inside of the flange e and the top side of the spigot, is to ensure the cement passing
around the pipe and flange and to make a good and solid joint.
A groove g is formed at the shoulder in the inside of the flange for the purpose
of making a clay joint before the cement joint is formed.
The rings and keys may be constructed in carthenware, Portland cement, or of
any other suitable material.
I am aware that rings on the spigot and inside the flange of pipes have been used
before but I am not aware that the rings have been connected by keys as herein
before described.
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. The key a to connect the rings, and c, on the spigot of the pipe, substantially
as herein described and according to the accompanying drawing.
2. The key a to connect the rings, and ", in the flange of the pipe, substantially
as herein described and according to the accompanying drawings.
3. The combination of the keys between the holes h, in the inside of the flange
and the top side of the spigot, to ensure the liquid cement passing around the pipe
and flange to make a good and solid joint, substantially as herein described and for
the purpose set forth.'
