PROVISIONAL SPECIFICATION.
Apparatus for Heating Water by an Ordinary Fire.
I, FRANK WALDEBRAND WALBRAND-EVANS, of Christ Church, Oxford,
Clerk in Holy Orders, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus whereby an ordinary fire is rendered available
for heating a large quantity of water, such as that required for a bath. For this
purpose, provide a kettle, preferably furnished with a safety valve and also
with a vacuum valve, and having a bent steam pipe extending from its upper part.
I suspend this kettle on an ordinary fire by a chain or cord which passes over a
pulley and has attached to it a weight less by a certain amount than the weight
of the kettle and its contents; or, instead of a pulley, a lever may be used, the
kettle being attached to the one arm and a counterweight to the other.
To the bent steam pipe I connect, by a screw union or otherwise, a pipe which
dips down into the water contained in a bath or other vessel of considerable
capacity. When the water in the kettle boils, the steam passes to the bath or
other vessel and heats the water therein, and, when a certain quantity of the water
in the kettle has boiled off so that the counterweight overbalances it, then the
kettle is raised from the fire, thus preventing such damage as might result from
deficiency of water in the kettle.

I, FRANK WALDEBRAND WALBRAND-EVANS Christ Church Oxford, Clerk in
Holy Orders, 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 an improved apparatus for heating water by an ordinary
fire and the object is to provide a simple & ready means for heating water by an
ordinary fire & the same is carried out as follows reference being had to the annexed
drawings in which
Figure 1, is a front elevation showing my apparatus.
Figure 2, side elevation to enlarged scale of heater & connecting tube.
a is the heater or kettle having the lid b. c is a cord connected to the heater
or kettle a at d and passes over the pulley e and has the weight or counterpoise f.
9 is a tube adjustably connected by the screw thread h & nut i to the tube j
which enters the tank or vessel k containing the water to be heated. The heater
or kettle a containing the water to be boiled is placed upon the fire and the steam
then passes down the tube ; & heats the water in the tank or vessel k. The
weight is for the purpose of raising the heater or kettle a from the fire / when
the water in same has boiled away to the desired amount thus preventing burning

upon the fire after the water in same has been boiled away.
Having now particularly described & ascertained the nature of my inven-
tion & in what manner the same is to be performed I declare that what I
claim is
1
.1.
1. In apparatus for heating water of the class herein described, the combination
and arrangement of the various parts substantially as described and illustrated
herein.
2. In apparatus for heating water a heater or kettle connected to a counterpoise
or weight so that when, the water in the heater or kettle has been boiled away or
evaporated to the desired amount, the heater or kettle will be raised or removed
from the heating surface or fire substantially as described & for the purpose set
forth.
