PROVISIONAL SPECIFICATION.
Improvements in Water Heating Apparatus.
I, JOSEPH WINTERFLOOD, Gas Engineer, of 173, Kings Road, Camden Town,
London, N.W., do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in water heating apparatus for domestic
and other purposes, and consists of the combination of a water heater, a ball valve
and a thermostat or thermostatic regulating device.
The ball valve regulates or controls the water supply to the water heater being
fitted to a water chamber arranged in the upper part of the heater, the opening
and closing of the draw off tap causing the opening and closing of the ball valve
and consequently allowing and checking respectively the supply of water to the
heater.
The thermostat regulates or controls the gas supply being fixed in any suitable
part of the heater and arranged with arms and levers operating same according
to the temperature of the water to open or close a gas valve controlling the gas
way to the heating device or burner.
J. WINTERFLOOD.
I, JOSEPH WINTERFLOOD, Gas Engineer, of 173, Kings Road, Camden Town,
N.W., London, 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 improvements in water heating apparatus for domestic
and other purposes, and consists of the combination of a water heater, a ball valve
and a thermostat or thermostatic regulating device.
The ball valve regulates or controls the water supply to the heater being fitted
to a water chamber arranged in the upper part of the heater, the opening and
closing of the draw off tap causing the opening and closing of the ball valve and
consequently allowing and checking respectively the supply of water to the heater.
The thermostat regulates or controls the gas supply being fixed in any suitable
part of the heater and arranged with arms and levers operating same according
to the temperature of the water to open or close a gas valve controlling the gas
way to the heating device or burner.
As shewn in the accompanying diagrams of which Figure 1 is a section eleva-
tion and Figure 2 an outside elevation, of my improved water heating apparatus;

page_text: I employ a water heater consisting of two or more double cylindrical casings,
the outer double casing 1 being of greater depth than the inner double casing
or casings 2.
Within the innermost double casing there is a cylindrical boiler 3.
An inlet 4
is arranged in the outer casing 1 and an outlet 5 is arranged in the boiler 3.
A cross stay 6 is fixed in the upper end of the outer casing, connecting the
various chambers so that a continuous water-course is formed from the outer
double casing 1 through the inner double casings 2 to the boiler 3.
A water chamber 7 is arranged in the upper part of the heater, being in con-
nection with the boiler 3 by a tubular stay 8. A ball 9 is placed in this chamber
being fixed to a rod 10 which operates a valve 11, opening or closing same accord-
ing to the fall or rise respectively of the ball which is so constructed as to float
on the water.
The said valve 11 controls the water way to the heater so that when the
operator opens the draw off tap 12 in the outlet of the heater the valve 11 simul-
taneously opens in consequence of the lowering of the level of the water and
therefore the fall of the ball.
If the operator now closes the draw off tap 12 the level of the water will rise
in the heater and on filling the double casings and the boiler the water flows
into the ball chamber 7 and raises the ball, the valve 11 simultaneously closing
in consequence thereof thus checking the supply of water to the heater."
The heating device may consist of a gas reservoir 13 upon which stands a
number of atmospheric or other gas burners.
The supply of gas is regulated or controlled by a gas valve 15 the stem of
which is connected to a rod 16 arranged with arms and levers so that the said
gas valve 15 is opened and closed by the action of the operating rod of the
thermostat 14.
The thermostat may be arranged in any suitable part of the water-course of
the heater.
In the accompanying diagram the thermostat is shewn securely fixed through
the outer double casing of the heater under the boiler, the operating rod 22 of
the themostat being hinged to a lever 20.
The said lever 20 is pivoted to a bearing 21 which is securely fixed to the outer
tube or stationary part of the thermostat, the lever 20 is also hinged to an arm 19
which is hinged to a second lever 17 this second lever 17 being pivoted to a
bearing 18 which is securely fixed to the outer casing of the heater. The said
lever 17 is connected to a rod or spindle 16 leading to the gas valve 15.
In the operation of the thermostatic regulating device the increase of the
temperature of the water operates the thermostat thereby actuating the levers to
close the gas valve, the decrease of the temperature of the water operates the
thermostat to actuate the levers in an opposite direction thereby opening, the
gas valve.
A small adjusting screw coupling 23 is arranged in the spindle 16 of the gas
valve, consisting of a sleeve fitted over a collar on the spindle and arranged to
screw on to the lower end of the upper part of the spindle connected to the
lever 17; the purpose of this coupling is to regulate the gas valve according to
the degree of temperature at which the water is required, for instance if the
water is required at a higher degree of temperature the adjusting coupling
must be screwed up somewhat thereby shortening the length of the spindle 16.
It now requires a greater expansion of the inner tube of the thermostat to close
the gas valve and therefore a higher degree of temperature of the water.
Having now particularly described and ascertained the nature of this invention
and the manner in which the same is to be performed I declare that what I
claim is:-
The improvements in water heating apparatus consisting of the combination
of a water heater, a ball valve regulating or controlling the water supply to the

page_text: heater, and a thermostat or thermostatic regulating device regulating or con-
trolling the gas supply substantially as and for the purpose herein set forth
described and illustrated.
