PROVISIONAL SPECIFICATION.
An Improved Pipe for Conveying Water, Soil, Gas, Waste and other
Products.
I, REGINALD FREDERICK YORKE of Barham, Canterbury Electrical Engineer,
do hereby declare the nature of this invention to be as follows :-
I construct my improved pipe in the following way :-
First I provide a cylindrical frame-work of metal, preferably iron, which may be
in the form of spiral wire hooping or iron netting. Then I arrange a core and also
a suitable mould vertically, and I insert the cylindrical frame-work midway
between the mould and the core, provision being made to keep the frame-work at
the top end of the mould.
I now fill up the remaining space between the core and the mould with concrete
or composition. The broken stone or material is first put in and then the liquid
cement is forced in under pressure, so as to avoid flaws and to ensure perfect
contact between the cement and broken material and the cylindrical framework.
Of course if preferred the concrete can be mixed first and then inserted under
pressure.
The mould and core being removed, the result produces, when set and dry, an
exceedingly strong pipe due to the combination as described of concrete and iron,
the former giving rigidity, and the latter strength and tenacity. This pipe will be
found capable of resisting considerable external or internal pressure and it can be
used advantageously in place of iron or steel pipes which are more expensive.

statement :-
1. construct my improved pipe in the following way
First I provide a cylindrical frame-work of metal, preferably of iron, which may
be in the form of spiral wire hooping or iron netting. Then I arrange a core and
also a suitable mould vertically and I insert the cylindrical frame-work midway

page_text: 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 herein before described process of making pipes, consisting in constructing
under pressure a pipe of concrete in combination with a metal frame.
2. Pipes of compressed concrete with a metal frame through the centre.
