Improvements in Instantaneous Water Heaters (Geysers) and
Automatic Valves for the same.

This invention is an improved instantaneous water heater, or
geyser," in which
the water is caused to travel over a larger surface and at a higher rate of speed,
with a view to increasing the rapidity and efficiency of the heating and to lessen
the deposit of lime or "fur"; a rising water course at the top allows free passage
and exit for the steam; and which is fitted with an improved automatic valve
wherein the flow of water opens the valve and allows the gas to pass to the burner
and when the flow ceases the pressure or weight of the water contained in the valve
and the geyser closes the valve and shuts off the gas.
The water heater or geyser" is constructed in the usual way with an outer
double cylinder or water jacket and one or more inner water jackets of cylindrical
or conical form, arranged concentrically or otherwise.
The various tubes or connections which convey the water from the supply into
the outer and inner water-jackets are so arranged that the water is projected in a
direction parallel or concentric with the sides of the double cylinders or water-
jackets.
The force of water entering in this direction causes the whole of the water in
the water-jackets to rotate or revolve, and this motion has the effect of keeping the
inside of the waterjackets clean and free from "fur," while at the same time
causing the water to travel over a larger surface and absorb mòre heat than if it
passed directly through the water jackets.
To allow free passage for the steam the top edge of the double water jackets is
made with a slight rise from one side to the other, the outlet being arranged at
the highest part and the inlet preferably at the lowest. Any steam generated in
any part of the water jackets would naturally rise to the highest point and thence
escape with the water into other water jackets or cylinders or into the open air
as may be desired.
The automatic valve for controlling the supply of gas according to the flow of
water is attached to the lower part of the geyser and is constructed as follows:
A cylindrical encasement has at one end (at the side) an inlet for the cold water
from the main and at the other end an enlargement, slots or holes through which
the water passes into the geyser.
Between this inlet and outlet is a moving piston or disc having a rod attached
the other end of which is connected with the gas valve. The gas chamber has an
inlet and outlet separated by a seating on which the gas valve rests when closed.
Between the water inlet and the gas valve is a cone, tube or diaphragm of india-
rubber or other flexible material, which being connected in effect at one end to the

page_text: interior of the water chamber and at the other end to the upper side of the gas
valve separates the water and gas chambers.
A collar, flange or tube is arranged on the gas valve to facilitate this connection
and also to leave a certain portion of the gas valve exposed to the water which fills
the india rubber tube or cone, such exposed portion being smaller in area than
the water piston described above.
When the cold water is turned on the pressure on the greater area of the water
piston overcomes that on the smaller exposed area of the gas valve and forces the
piston as far past the enlargement or holes as is necessary to allow the water to
pass into the geyser. . The connecting rod or wire raising the gas valve admits the
gas to the burner.
On the flow of water ceasing or being reduced below a safe quantity the pressure
or weight of the water contained in the geyser and the valve acting on the other
side of the water piston and the exposed part of the gas valve forces them down
in their original position and so shuts off the gas.
This valve does not require any weights or springs, the pressure of the water
alone moving it in each direction and it can be arranged vertically, horizontally
or in any position most convenient for the purposes of connection.

Improvements in Instantaneous Water Heaters (Geysers) and
Automatic Valves for the same.
I, THOMAS EUSTACE BARRALET, of "Dunkerry," Sidney Road, New Southgate,
London, Secretary, 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 is an improved instantaneous water heater or geyser, in which
the water is caused to travel over a larger surface and at a higher rate of speed,
with a view to increasing the rapidity and efficiency of the heating, and to to lessen
the deposit of lime or "fur"; a rising water course at the top allows free passage
and exit for the steam; and which is fitted with an improved automatic valve
wherein the flow of water opens the valve and allows the gas to pass to the burner
and when the flow ceases the pressure or weight of the water contained in the
valve and the geyser closes the valve and shuts off the gas.
Referring to the annexed drawings, Figure 1 shews the apparatus in section,
Fig. 2 shews the rising water course, Fig. 3 is a plan of the top, Fig. 4 shews
method of directing the water into the chambers, and Fig. 5 is an enlarged section
of the automatic valve.
The water heater or geyser is constructed in the usual way, with an outer double
cylinder or water Jacket (d) and one or more inner water jackets (g, g) of cylindrical
or conical form, arranged concentrically or otherwise.
The various tubes or connections (f, f) which convey the water from the supply
into the outer and inner water jackets are so arranged (c, c¹, c) that the water is
projected in a direction parallel or concentric with the sides of the double cylinders
or water jackets.
The drawings at Fig. 4 indicate several methods of effecting this; by a bent
tube (e), perforations in the side of a tube with closed end (c¹), a baffle or check in
the interior of the water jacket (e) etc.
The force of the water entering in this direction causes the whole of the water con-

page_text: tained in the water jackets to revolve or rotate, and this motion has the effect
of keeping the inside of the water jackets clean and free from "fur," while at the
same time causing the water to travel over a larger surface and absorb more heat
than if it passed directly through the water jackets.
To allow free passage and exit for the steam, the top edge of the double water
jackets (g, g) is made with a slight rise from one side to the other, the outlet being
arranged at the highest part and the inlet preferably at the lowest (Fig. 2). Any
steam generated in any part of the water jackets would naturally rise to the highest
point and thence escape with the water into other water jackets or cylinders or
into the open air as may be desired.
The automatic valve for controlling the supply of gas according to the flow of
water is attached to the lower part of the geyser, and is constructed as follows
(Figs. 1 and 5).
A cylindrical or dome-shaped encasement has at one end (at the side) an inlet
for the cold water from the main (a) and at the other end an enlargement, slots or
holes, through which the water passes into the geyser by the connection (s).
Between this inlet and outlet is a moving piston or disc (b) having a rod attached
the other end of which is connected with the gas valve (t).
The gas chamber has an inlet (k) and outlet (7) separated by a seating on which
the gas valve rests when closed.
Between the water inlet (a) and the gas valve (t) is a cone, tube or diaphragm
of india-rubber or other flexible material (r), which being connected in effect at
one end or at the outer edge to the interior of the water chamber, and at the other
end or in the centre to the connecting rod or the upper side of the gas valve,
separates the water and gas chambers.
When the cold water is turned on the pressure on the piston (b) forces it as
far past the enlargement or holes as may be necessary to allow the water to pass
into the geyser. The connecting rod or wire raising the gas valve admits the gas
to the burner (m). A pilot jet or slight leak through the valve leaves a small
flame to avoid any escape of unburnt gas.
On the flow of water ceasing or being reduced below a safe quantity the pressure
or weight of the water contained in the geyser and valve acting on the other
side of the piston (b) and the surface of the cone or diaphragm (r) forces them
down into their original positions and so shuts off the gas.
This valve does not require any weights or springs, the pressure of the water
alone moving it in each direction, and it can be arranged vertically, horizontally
or in any other position which may be most convenient."
The water after passing the valve enters the outer double cylinder or water
jacket of the geyser (d) through the bent or perforated tube (c, c³) which gives it
the rotatory motion already described, enters the water jackets (g, g) by the
channel (e) and the tubes or connections (f, f) which are provided with the deflect-
ing inlets (e, e¹, c), leaves the water jackets by the outlet at the highest part
(Fig. 2) and passes by the channel (e¹) into an inner reservoir or boiler (h).
Having become heated by the gas at the burner (m) it runs out at the spout (j)
into any receptacle which may be placed to receive it."
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. A geyser or water heater with the parts arranged as shewn in the annexed
drawings and working in the manner and for the purposes described.
2. A geyser in which the water is projected or injected into the chambers or
cylinders in such a manner as to cause the contained water to revolve or rotate.
3. The construction of the double cylinders or water jackets with a rising or
sloping top edge, substantially as shewn in Figure 2 of the annexed drawings and
described herein.
4. The automatic valve for controlling the supply of gas according to the flow

page_text: of water, with a piston which is forced out of place by the flow, and a flexible cone
or diaphragm which is acted on by the pressure or weight of the water contained
in the valve and geyser to close the gas supply when the flow of water ceases or is
reduced below a safe amount, substantially as shewn and described.
