Hackney Road, London E., Hydraulic & Gas Engineer, do hereby declare the
nature of our invention for AN AUTOMATIC HOT WATER CISTERN REGULATOR FOR
REGULATING THE TEMPERATURE, USE OF HEATING FUEL, & WATER SUPPLY TO HOT
WATER CISTERNS, URNS, KETTLES ETC, to be as follows:-
In the construction of this invention we employ either a piston & cylinder, or
other means actuated by the expansion of water, air, or any inetal or substance so
arranged as to open & close our cold or hot water supply, or both, by the means
above described or to regulate the supply of gas or other fuel. The expansion
force as above specified is so employed, & arrangements made, so as to act as a
check to the water supply, or fuel supply, & may be fitted inside or outside the hot
water cisterns or tanks.

An Automatic Hot Water Cistern Regulator.
We ADOLPHE EMILE HUBERT of 15 Bloemfontein Road Uxbridge Road
London W. Architect & Sanitary Engineer, and WILLIAM WALKER FYFE
50 Tuilerie Street Hackney Road London E. Hydraulic and Gas Engineer, do
hereby declare the nature of our invention for "AN AUTOMATIC HOT WATER
CISTERN REGULATOR" 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 automatic.hot water cistern regulator for regulating
temperature, regulating the use of heating fuel, regulating water supply to hot
water cisterns, urns, kettles and so forth, the effect being the operating of a valve
or check to open or close the same against a passage or source of supply or escape.
In carrying out our invention we employ either a piston and cylinder or other
means actuated by the expansion of water, air or any metal or substance so arranged
as to open and close either the cold or hot water supply or both or to regulate the
supply of gas or other heating fuel. The expansion force of the water or air or of
the metal or other substance is employed, as will be hereinafter more fully described,
in such manner as to act as a check to the water supply or the fuel supply and the
apparatus is so arranged that it may be fitted either inside or outside the hot water
cistern tank or urn as may be convenient or it may operate the valve or valves to
regulate the supply of heated liquid or refrigerating medium from a container to a
system of heating, or cooling pipes.
In the accompanying sheet of drawings Fig. 1 shows partly in vertical section a
regulator constructed according to this invention and as applied to an urn or other
vessel for regulating the supply of gas or heating fuel, such as hydro-carbon oil or
other like gaseous, or liquid fuel to its burner.. Figs. 2 and 3 are transverse
sections of the apparatus at lines A, B, and CD.
Fig. 4 shows an arrangement of the apparatus adapted to a hot water cistern for
regulating the supply of hot or cold water and in this case the interposition of an
electrical current is employed to operate the supply or discharge valve.
Figs. 5, 6 and 7, show modifications of the apparatus.
a Fig. 1 represents the bottom sheet of an urn, or hot water cistern, bis metal
block with gas passage c and a bulb or chamber d, for mercury, when the heat rises
to a certain degree the rising mercury will close the gas passage c at c¹, e are screw
unions, is a burner of suitable kind.

sequent upon the rise in temperature will close the circuit in the mercury. g
and the armature will be attracted to the electro magnet i so operating the
lever (pivoted at ¹ to a standard or arm) to open or close the valve as the case
may be whether of the fuel supply or of the cold water supply or. for supply of
water at a given temperature to open the discharge valve l.
.In Fig. 5 is shown a mercury column which may have a graduated scale or not
and to the mercury bulb d is connected one wire of an electric circuit and the other
wire of the circuit is connected to a contact piece m inserted in the upper end of
the column and when the mercury rises or falls consequently upon elevation or

and as will be well understood by any.clectrician.
Fig. 6 represents a float n in a mercury bulb d which by rise or fall of
tomperature will elevate or lower the piston o in tube g to act directly upon or
to close a current to operate a lever of a valve for the regulation or supply to or
from the container.
Fig. 7 represents a mercury bulb, or bulb for hot water, spirit, compressed air, or
other similar medium, for operating a piston (not shown) but that will be capable
of operating by float or otherwise within the tube g, to rise and fall and operate a
valve through suitable connections for the purposes set forth.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
+
Firstly. The improved means of and apparatus for automatically regulating
supply or discharge either of fluid contents, whether gaseous or liquid or of liquid
fuel to cisterns or containers or chambers as herein set forth and shown by the
drawings. .
Secondly. In combination with the mercury bulb and tube g, the electric circuit
for operating an electro magnet armature to operate the supply or discharge valve
or valves as herein set forth and shown by the drawings.
