PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Preventing
Water and Gas Pipes from Freezing.
I, ROBERT GILL THWAITES, of 1, Wrangthorne Terrace, Royal Park, Leeds,
Tinplate Worker, and Gas Stove Maker, do hereby declare the nature of this
invention to be as follows:-
The object of my invention is to prevent the freezing, indoors, of water and .
gas pipes.
In carrying out my said object, I effect a continuous circulation of the water in
the cistern by connecting what is known as the "outlet" pipe to a boiler having a
pipe connecting it with the cistern, the water from the cistern being fed to the
cylinder and boiler, and up to the bath or lavatory in the ordinary way.
The boiler (connected with the "outlet" pipe and cistern) is provided with a
suitable gas heating arrangement, so that when the fires are out for the night, the
necessary temperature to maintain the free or continuous circulation aforesaid can
be obtained.
A tap may be provided adjoining the "outlet" pipe to the boiler for stopping
the continuous circulation when not required.
Dated this 11th day of January 1892.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Preventing
Water and Gas Pipes from Freezing.
I, ROBERT GILL THWAITES, of Wrangthorne Terrace, Royal Park, Leeds,
Tinplate Worker and Gas Stove Maker, 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 :-
The object of my invention is to prevent the freezing, indoors, of water pipes.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a general view showing my improvements applied.
Fig. 2, is an elevation partly in section showing boiler and gas heating arrange-
ment therefor.
In carrying out my said object I effect a continuous circulation of the water
in the cistern A by connecting, by means of pipe B, what is known as the
"outlet" pipe C (from the cylinder) to a boiler D having a pipe E connecting
it with the cistern A, the water from the cistern being fed to the cylinder and
boiler and up to the bath or lavatory in the ordinary way. F is the supply pipe
to the cylinder and G supply pipe to the cistern A.
The boiler D consists of a copper shell D' (corrugated or plain) enclosed in a
cast iron shell D' pivotted or otherwise secured upon a circular gas stove H, H¹ are
ledges for the shell D' to rest upon.
The copper shell D' is constructed with an internal chamber D³, which is filled
with asbestos balls or pieces made to the shape of walnuts or other suitable

page_text: shape. D is the boiler inlet pipe connected with pipe B, and D is the boiler
outlet pipe connected with the pipe E, to the cistern. J is the gas pipe.
By connecting a pipe K from the outlet pipe C to the supply pipe F the apparatus
can be used for hot water purposes.
L, M, N, and P are the necessary taps. When using the apparatus for hot water
purposes the taps L and P should be opened and the tap M closed. When using
the apparatus to prevent freezing of the pipes the tap L should be closed and the
taps M and P opened.
The tap P is for stopping the continuous circulation when not required.
When the fires are out for the night the necessary temperature to maintain the
free or continuous circulation aforesaid can be obtained by lighting the stove or
leaving it burning if already lighted. If preferred, an oil stove may be used instead
of a gas one, or where gas is not available.
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. Preventing water pipes from freezing by effecting a continuous circulation of
warm water through the cistern and pipes conducting the water to and from the
cylinder or boiler, substantially as set forth.
2. The construction of boiler heated by gas, or oil such as, and for the purposes,
shown and described.
