Improvements in Geysers, and in Means for Obtaining Constant
Supply of Water thereto and therefrom as desired.
We EMILE ALEXANDRE PORCHER of 52 Rue d'Hauteville, Paris, France,
Hardware Merchant, and JOSEPH WINTERFLOOD of 39 Thornhill Road,
Barnsbury, London, Engineer do hereby declare the nature of this invention to be
as follows:-
This invention has for object improvements in geysers and in means for obtaining
constant supply of water thereto and therefrom as desired.
For the purpose of my invention I attach to or form part of a geyser a supply
cistern in which is a stop or ball cock in connection with the main or surface supply
in order that the supply to the geyser is independent of any head of water which
heretofore has acted injuriously to geysers as now constructed.
The introduction of a supply and automatic shut off enables the present geysers
to be furnished with a draw off pipe for the supply of water therefrom to any lower
part of a building instead of limiting said supply to a vessel in proximity to it.
The supply water can first feed the geyser and then should the draw off tap be
closed the water from the geyser can flow into the cistern and lift the ball to shut
off the feed.
Dated this 19th day of March 1895.

Improvements in Geysers, and in Means for Obtaining Constant
Supply of Water thereto and therefrom as desired.
We, EMILE ALEXANDRE PORCHER, of 52 Rue d'Hauteville, Paris, France,
Hardware Merchant, and JOSEPH WINTERFLOOD, of 39 Thornhill Road,
Barnsbury, London, Engineer, 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 has for object improvements in geysers and in means for obtaining
constant supply of water thereto and therefrom as desired.
For the purpose of this invention, we attach to or form part of a geyser a supply
cistern in which is a stop or ball cock in connection with the main or service pipe
in order that the supply to the geyser is independent of any head of water which
heretofore has acted injuriously to geysers as now constructed.
The introduction of a supply and automatic shut off enables the present geysers
to be furnished with a draw off pipe for the supply of water therefrom to any
lower part of a building, and in certain cases to a slightly higher level than that of
the geyser, instead of limiting said supply to a vessel in proximity to it.

page_text: The supply water can first feed the geyser and then should the draw off tap be
closed, the water from the geyser can flow into the float chamber and lift the ball
to shut off the feed, or by a first or direct supply to the geyser, the water can be
directed to the cistern for action on the float for shutting off the supply, or it can
be directed to an extension pipe for delivery at a slightly higher level.
Referring to Figure 1 of the annexed drawings, A is the outer casing. B a supply
cistern therein. Ca float in said cistern for governing the action of the valve D
of the inlet or service pipe E, said pipe E terminating in the cistern B for feeding it.
F is a branch pipe leading to a down-flow pipe G by which the geyser is filled,
said pipe G being attached to a tube H provided with a valve J which is lifted by
the pressure of the inflowing water to pass the bulb K and enter the chamber
between the outer casing A and inner casing L, and thence by an overflow into
circular, depending vessels M, M, until it enters the two boxes N, N, which are
connected by a cross pipe P. Each box is provided with a baffle plate Q, Q, to
check a sudden inrush of water. When the geyser becomes full of water, the
additional inflow backlashes or reacts in the branch F and fills the cistern, this lifts
the float C and automatically shuts off the valve D and stops the supply from the
service pipe E. R is an inner vessel into which water from one of the boxes N
can flow by the pipe S. T is the draw off tap which when opened allows the water
to flow out of the geyser, this causes the float C in the cistern to lower to reopen
the valve D for a fresh supply, said supply being continuous until the draw off
tap T be again closed for the inflowing water to rise in the cistern B to lift the
float C which again closes the valve D. By this arrangement, the action of filling
the geyser, shutting off the supply of water, and of reopening the valve for å
fresh supply is automatically performed.
With the draw off tap, we purpose using a depending or side branch U to lead
to some lower part of a building to enable water to be drawn out of the geyser at
any place below and other than where the geyser is fitted.
The rod V of the valve J has also a valve W at its lower end for governing the
passage of gas from the feed pipe X to the burner Y said rod being pressed down
by a spring to keep the lower valve W on its seating except when the pressure of
water flowing through the tube H into the geyser lifts the valve J at which time
only is the lower or gas valve W opened, so that should the water either to the
geyser or from the geyser be shut off from any cause, the gas flame becomes
simultaneously extinguished except to a small flicker or pilot light for fully
regulating the burners when the water next flows from and into the geyser.
According to Figure 2, a slight modification is introduced.
In this arrange-
ment, the cistern B and float C in the geyser are retained, but instead of the
branch F being in a piece with the flow down pipe G, said branch F is in coD-
nection with the draw off tap by the pipe Z, so that the cistern B is only used for
reception of water after the geyser is filled, and then by the water rising in the
cistern for lifting the float the valve D becomes shut and stops the supply.
The branch pipe F in this modification has a three way tap a at the junction b,
aud said tap a can be turned for water to flow into and from the cisteru B, or be
turned for water after passing through the geyser to enter the extension pipe c and
be carried to a slightly higher level than that at which the geyser is fitted, such as
for a shower bath, the pressure of water from the main or head of supply being
sufficient for this purpose.
It may be here observed that the apparatus is relieved of all strain from the
pressure of a head of water because the inlet water can only flow into it when
the float lowers to open the valve D, such as when the water is being drawn off
by the tap T, or by the pipe U for supplying water to a lower part of a
building.
The apparatus is intended for water heating purposes by gas flames, and to
effect this the lower part of the tube H is connected with the gas inlet X for
charging the chamber d, and in order to prevent escape of gas to the burner Y,
unless the water be first allowed to flow into the apparatus, the water valve J has

page_text: connected to it the rod V of the gas valve W which can only rise from its seating
when the valve J rises under pressure of the inflowing water from the pipe G.
To prevent gas passing into the bulb K, the valve J and the collar of the gas
valve W have a short length of india rubber tubing e affixed.
The gas burner Y is of the swing kind to admit of its being brought out from
the stand in any suitable manner for lighting it, and to regulate the consumption
the pipe X is provided with a tap g.
The lower part of the casing L has a cone shaped barrel h to narrow the neck i
for centralizing the heat arising from the flames against the bottom of the vessel R
from which heated products spread outwardly and imparts heat to the annular
vessels M, M, as well as to the vertical sides of the central vessel R and the
vertical walls of the inner casing L thence after striking against the bottom of the
boxes N, N, and the connecting pipe P the fumes pass out from the apparatus by
the flue into the atmosphere or by a chimney as desired.
k is a pipe for leading the condensation of the annular vessels M, M, and central
vessel R into the trough from which it trickles down the pipe m.
The features of novelty in this invention are:-
1. The apparatus is relieved of all pressure of a head of water.
2. Water can only enter the apparatus when the float automatically lowers.
3. The water supply is automatically shut off when the apparatus is filled.
4. The apparatus can never overfill."
5. Water can be drawn from the apparatus to supply lower apartments without
necessitating attention.
6. Water can be withdrawn from the apparatus at a distance from it and at a
higher level than that of the apparatus on adjustment of a tap.
7. No gas can pass to the burner unless the water be already flowing through
the apparatus.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A geyser or water heater with the parts arranged as shown on the annexed
drawing and acting in the manner and for the purposes described.
2. In a geyser or water heater, a contained cistern with float for opening the
feed and for automatically closing a water supply valve by back action after such
water has filled the geyser substantially in the manner set forth.
3. In a geyser or water heater, a contained cistern with float for automatically
opening water feed, and for automatically closing said feed after geyser is filled, or
for continuous flow to a slightly higher level.
4. In a geyser or water heater, a tap such as a in a branch F for leading the
float water to tap T or U, or for permitting water to pass by pipe c to a slightly
higher level than that of the geyser, as set forth.
5. Providing means by which water can be supplied to an outlet above the level
of a geyser in combination with the means for supplying water from the geyser at
the same or at a lower level or levels, as described.
