page_text: I, WILLIAM OLIPHANT, of 21, Clifford Street, in the County of the City of
Glasgow, North Britain, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to provide a simple, effective and automatic
instantaneous water heater.
In carrying out my invention, I provide a tank of any suitable shape and size in
which there is carried a coil of pipes, and a burner or series of burners according
to the size of the tank. A pipe leading from the main or any other source of
supply is connected to a valve which in turn is connected to another pipe leading
to the tank. The valve spindle herein is connected to the stop cock or valve
through which the gas passes and is so constructed that as the water is turned on
it opens the valve and allows it-the water-to pass into the tubes in the tank.
So soon as the valve opens, the gas is automatically turned on, when it finds its
way into the burner. A pilot burner, which is provided for the purpose is then
lit, when the burner or burners inside the tank become lit and the water circulating
through these tubes becomes heated and passes out at the opposite end through
an outlet provided for the purpose. Baffle plates are provided on the burners so
as to spread the flame.
So soon as the flow of water is stopped, the gas in a similar manner is instantly
shut off again.
In place of having the gas turned on and shut off automatically as described,
I may provide a hand cock for this purpose.
Dated this 6th day of April 1898.

page_text: and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement;
My invention has for its object to provide a simple, effective and automatic
instantaneous water heater.
In carrying out my invention, reference being made to the accompanying
drawing, I provide a tank A of any suitable shape and size in which there is
carried a coil of pipes B, and a burner or series of burners C according to the size
of the tank A. A pipe D leading from the main or any other source of supply is
connected to a valve E which in turn is connected to another pipe F leading to
the tank A. The valve spindle e herein is connected to the stop cock or valve G,
through which the gas passes, by means of a weighted arm or lever H, and is
so constructed that as the water is turned on it opens the valve E and allows it
―the water to pass into the tubes B in the tank A. Simultaneously with the
opening of the valve E the stop cock or valve G, through which the gas passes,
from the pipe K is also opened and the gas is automatically turned on, when it
finds its way into the burner or burners Č. A pilot burner I, which is provided
for the purpose is then lit, when the burner or burners C inside the tank A become
lit and the water circulating through these tubes B becomes heated and passes out
at the opposite end through an outlet J provided for the purpose, or a bye-pass may
be provided for lighting the burners. Baffle plates are provided on the burners
so as to spread the flame.
So soon as the flow of water is stopped the gas in a similar manner is instantly
shut off again by the falling of the weighted arm or lever H.
In place of having the gas turned on and shut off automatically as described
I may provide a hand cock for this purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I wish it to be understood
that I am aware that it is not novel to construct a water heater with a coil of pipes
enclosed in a casing and heated by gas burners, nor to employ an automatic
device, consisting of two valves connected together, for controlling the supply of
gas by the flow of the water to be heated, and I make no general claim to either
of these features, but I declare that what I claim is:
-
In water heaters, the general arrangement, combination, and operation of the
parts, substantially as described and illustrated on the accompanying sheet of
drawings.
