PROVISIONAL SPECIFICATION.
Improvements in Metallic Pipes and Tubes for Conveying Water
or other Aqueous Liquids to Prevent Bursting by Frost, and
Machinery for Effecting the said Improvements.
I, STEPHEN JOHN NEWMAN, 155, Upper Thames Street, London, Iron Merchant,
do hereby declare the nature of this invention to be as follows:-
According to this invention one or more plaits or folds is or are formed laterally
and longitudinally in a metallic pipe or tube, for conveying water or other aqueous
liquid, to allow of the expansion of such pipe or tube under the pressure of the
water or other liquid contained therein when such water or other liquid is frozen,
thus preventing the bursting of such pipe or tube.
I prefer to make such plaits or folds in the pipes or tubes by passing the latter
through rollers which have suitable grooves and recesses formed therein of any
suitable shape to produce such plaits or folds, but the latter may, if desired, be
formed either by stamping, hammering, or in any other convenient manner, and
may be either internal or external, and of any suitable section, while the pipes or
tubes may be of any desired shape.
Dated this 1st day of September 1894.

Improvements in Metallic Pipes and Tubes for Conveying Water
or other Aqueous Liquids to Prevent Bursting by Frost, and
Machinery for Effecting the said Improvements.
I, STEPHEN JOHN NEWMAN, 155, Upper Thames Street, London, Iron Merchant,
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 :-
According to this invention one or more plaits or folds is or are formed laterally
and longitudinally in a metallic pipe or tube for conveying water or other aqueous
liquid to allow of the expansion of such pipe or tube under the pressure of the
liquid contained therein when such liquid is frozen thus preventing the bursting of
such pipe or tube. The plaits or folds may be of any suitable section and either
external or internal while the pipe or tube may be of any desired shape.
Figures 1 and 2 of the accompanying drawings shew views in elevation and
cross section of a pipe or tube made according to my invention having a single
plait or fold a formed therein and
Figure 3 is a section of a pipe or tube having two such plaits or folds.
The plaits or folds may be produced either by hydraulic or other pressure when
making the pipe or by subsequently passing the pipe or tube between rollers having
Pine R17

page_text: suitable grooves and recesses formed therein for that purpose, or they may be
produced by stamping, hammering, or in any other convenient manner. I therefore
make no claim to any particular means for producing such plaits or folds and I
hereby disclaim so much of the title of my present invention as relates to
machinery for effecting the same.
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
As a new article of manufacture a metallic pipe or tube having one or more
plaits or folds formed therein all substantially in the manner and for the purpose
hereinbefore specified.
