PROVISIONAL SPECIFICATION.
Instrument for Preventing Water Pipes from Bursting.
1, HENRY EDWARD BURNET of 50 Queen's Road Peckham, S.E. Collector of
Queen's Taxes do hereby declare the nature of this invention to be as follows:-
It consists of a length (or lengths) of suitable elastic material (such as india
rubber, cork &c.) protected & strengthened by another thin material such as sheet
metal or canvas, of such dimensions that it may be inserted within the pipe to be
protected without materially diminishing the supply of water..
The lengths of the material may be flat, round, half round, or any suitable shape
& should in most cases extend as near as possible the whole length of the pipe to
be protected.

COMPLETE SPECIFICATION.
Instrument for Preventing Water Pipes from Bursting.
I HENRY EDWARD BURNET of 56 Queen's Road Peckham in the County of
Surrey Collector of Queen's Taxes 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 relates to a method and means for preventing the bursting of
water pipes when the water in such pipes becomes frozen and will be found to be
equally effective time after time when frequent frosts cause frequent freezing of the
water in the pipes.
My present invention consists of a length (or lengths) of suitable elastic material
(such as and advantageously cork) protected and strengthened by a covering or
partial covering of another thin material such as thin sheet metal canvas etcétera
the "preventer "thus constructed being of such dimensions that it may be inserted
within the pipe to be protected without materially diminishing the supply of water.
The lengths of the material may be flat round half round or any other suitable
shape in cross section and should in most cases extend as near as possible the whole
length of the pipe or pipes to be protected.
The said material for protecting and strengthening the said elastic material may
be sheet lead sheet compo tinned lead wire canvas or the like and may be perforated
with holes at any suitable distance from one another or have a slit or slits in it
which slit may extend the whole length of the instrument or have both slits and
holes therein.
I would here remark that I do not consider india rubber to be the most advan-
tageous elastic material for my purpose as it is liable to foul or affect the water.
The said instrument or "preventer "may be kept in position inside the pipe to
be protected by one or more arms or projections formed thereon or attached to it
or by a tube or tubular shaped piece of metal inserted within the pipe to be
protected together with the said instrument the said tube or tubular shaped piece
of metal may extend the whole or part of the length of the instrument.
And in order that my present invention may be easily understood and readily
carried into practice I will proceed to further describe my said invention with
reference to the drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
The several figures of the drawings annexed illustrate various ways of carrying
out my invention...

Figure 7 shows an oblong shaped "preventer" inserted in the pipe A.
A represents the pipe to be protected, B the elastic substance, C the strengthening
and protecting material.

•
D the slit (or one of the holes or slits) in the covering, E the projections on the
instrument or
65 preventer to keep it in position within the pipe these projections
may be at the end or ends of the instrument or at intervals along its length or
they may extend the whole of its length.
Ein Figure 2 represents a tube or tubular shaped metal inserted into the pipe
to be protected (together with the instrument or preventer B C) either part or
the whole of its length to keep the said instrument in position.
The operation is as follows:-
i. of frost the expansion caused by the freezing of the water compresses and
contracts the elastic material B within the covering Cor compresses the covering C
together with the material B and so avoids bursting the pipe A.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I would remark that I
herein make no claim whatever to india rubber alone inserted in a water pipe but
what do claim is :-
1. The combination of cork with a covering or partial covering of flexible sheet
metal or other suitable material together forming a "protector or instrument for
inserting in water pipes to prevent same bursting when the water is frozen therein
substantially as and for the purposes herein before described and set forth.
2. The combination of any suitable elastic material with any suitable flexible
metallic or other suitable covering or partial covering such combination forming a
protector or instrument to insert in water pipes to prevent same bursting when the
water is frozen in same substantially as and for the purposes hereinbefore described
and set forth.
