PROVISIONAL SPECIFICATION.
Improvements in Pipe Joints.
I BENJAMIN POWELL of 84 Bank Street South Melbourne in the Colony of
Victoria, Civil Engineer do hereby declare the nature of my invention. to be as
follows:-
.
This invention is applicable to pipes made of iron or other metal, earthenware
or other suitable material, and the object of the invention is to construct a pipe for
sewers, drains, electric conduits, water supply and other like purposes that with
ordinary care in laying down will effectually prevent leakage, and will maintain a
secure joint in subsiding ground.
The joint is so constructed, that although any portion of the pipe line may be
removed without destroying its continuity, they cannot be drawn asunder
longitudinally like the ordinary socket jointed pipes.
In order to render the description clear I annex a sheet of drawings, similar
letters refer to similar parts in any of the figures.
Fig. 1, vertical longitudinal section through the pipes.
Fig. 2, elevation of end of pipe.
I construct one half of each end of each pipe with a raised bevelled bead A, this
bead fits into a corresponding bevelled groove formed in a projecting flange B, also
made on one half of the end of the adjoining pipe.
The other half of each end of each pipe is constructed with a projecting flange
such as before mentioned and marked B, having an internal bevelled groove C,
formed in it, to receive the bevelled bead A, on the adjoining pipe.
A space D, is allowed between the adjacent parts of the pipes for jointing
material, this space may vary in width to suit the nature of the material used.
On the face or seat E, of each projecting flange B, I make a small groove F, to
form a key for the jointing material.
The proportions of the parts may be varied from those shown in the drawing,
and it will be seen that the pipe P, can be raised vertically from its position, by
virtue of this joint, which I call "The National Pipe Joint," without in any way
disturbing the adjacent pipes.

Improvements in Pipe Joints.
I, BENJAMIN POWELL of 84, Bank Street, South Melbourne, in the Colony
of Victoria, Civil Engineer 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 is applicable to pipes made of iron or other metal, earthenware or
other suitable material, and the object of the invention is to construct a pipe for
sewers, drains, electric conduits, water supply and other like purposes that with
ordinary care in laying down will effectually prevent leakage, and will maintain a
secure joint in subsiding ground. The joint is so constructed, that although any
portion of the pipe line may be removed without destroying its continuity, they
cannot be drawn asunder longitudinally like the ordinary socket jointed pipes.

page_text: In order to render the description clear i annex a sheet of drawings, similar
letters of reference indicate similar parts in any of the figures.
Fig. 1, vertical longitudinal section through the pipes.
Fig. 2, elevation of end of pipe.
Fig. 3, plan of joint at E.
Fig. 4, elevation of joint.
I construct one half of each end of each pipe with a raised bevellel bead A, this
bead fits into a corresponding bevelled groove formed in a projecting flange B, also
made on one half of the end of the adjoining pipe.
The other half of each end of each pipe is constructed with a projecting flange
such as before mentioned and marked B, having an internal bevelled groove C,
formed in it, to receive the bevelled bead A, on the adjoining pipe.
A space D, is allowed between the adjacent parts of the pipes for jointing
material, this space may vary in width to suit the nature of the material used.
On the face of seat E, of each projecting flange B, I make a small groove F, to
form a key for the jointing material.
The proportions of the parts may be varied from those shown in the drawing, and
it will be seen that the pipe P, can be raised vertically from its position, by virtue
of its joint, which I call "The National Pipe Joint," without in any way disturbing
the adjacent pipes.
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 improved pipe joint substantially as hereinbefore described and illustrated.
2. In the jointing of pipes, constructing each end of each length of pipe with a
semicircular flange B, having an internal groove C, and at the opposite side a
semicircular raised bead A, to fit into the groove C, of the adjacent pipe, the
faces E, of the abutting ends of flanges B, being provided with grooves F, to form
a key" substantially as hereinbefore described and illustrated.
