I, JOSEPH WINTERFLOOD, Engineer, of 173, King's Road, Camden Town, County
of London, do hereby declare the nature of this invention to be as follows:
-
This invention relates to certain improvements in water heaters of the kind
known as geysers specially designed to constitute a rapid heating of water in small
yet continuous streams for domestic and other purposes, whereby the application
of heat to the water receptacle cannot take place until a water supply has been
introduced. to it.
For the purpose of this invention I construct a hollow corrugated cylinder which
stands vertically within an outer cylinder. The top face of the said corrugated
cylinder is made convex and the lower edge of said corrugated cylinder rests upon
the outer surface of a hollow frustum of a cone which terminates at its base in
the outer cylinder. The corrogated cylinder is perforated near its lower edge
with a series of holes and near its top with a few holes for the purpose of which
is hereafter mentioned.
Above the corrugated cylinder I fix a bossed plate into a groove round the outer
cylinder.
The top surface of this plate is convex and the plate has narrow strips extracted
from it near to its edge and also a hole stamped in its centre, to allow the water
pouring from a pipe projecting over the plate, to flow through it on to the top of
the corrugated cylinder and run down the sides of the corrugated cylinder and
outer cylinder, into a receptacle formed by the junction of the cone and outer
cylinder.
Above this junction a spout is fixed to the outer cylinder forming an outlet for
the hot water and thus a continual water course is formed.
In the lower part of the outer cylinder I place a gas reservoir containing a
number of gas jets, the said reservoir being in connection with a gas cock fixed on
the outer cylinder.
Directly above this gas cock I fix a water cock to the outer cylinder connected
with a branch tube to the pipe projecting over the bossed plate. The keys or
spanners or handles of the gas and water cocks are so constructed and arranged
that the gas cock cannot be turned on until the water cock has been turned on
and the water cock cannot be turned off or closed until the gas cock has been
turned off; this locking gear arrangement being as follow,
When both cocks are closed, the key of the water cock rests against the key
of the gas cock in such a manner as to lock the gas key which now cannot be
turned to open the gas cock until the key of the water cock has been turned to
open the water cock.
The gas key acts in a similar manner on the water key when both cocks are
open, preventing the water cock being shut until the gas cock is shut.
I provide a small tube leading from the gas inlet to a gas jet for the purpose
of a pilot light which should always be left alight.

plate into the ventilation pipe.

Improvements in Geysers.
I, JOSEPH WINTERFLOOD, Engineer, of 173, King's Road, Camden Town, County I
of 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 certain improvements in or applicable to water heaters
of the kind known as geysers, specially designed to constitute a rapid heating 1
of water, for domestic and other purposes whereby the application of heat to the
apparatus cannot take place until water has been introduced thereto and the water
cannot be cut off from the apparatus until the gas is turned off.
For the purpose of this invention, I construct a hollow corrugated cylinder to
stand vertically within a cylindrical casing or jacket. The top face of the
corrugated cylinder is convex and the lower edge rests upon the outer surface of a
hollow frustum of a cone which spreads to its base to the diameter of the cylindrical
jacket, this junction forming the water receptacle.
The corrugated cylinder is perforated by a number of holes near its lower edge
and a few holes near its top and above it is a convex bossed plate fixed in a groove 2
in the cylindrical jacket, the said plate being perforated by a hole in its centre
and a series of slots near its edge. A pipe projecting over the bossed plate leads
from a water cock and forms the inlet for the water which flows upon the bossed
plate and issuing through the perforations of same runs down the sides of the
corrugated cylinder and cylindrical jacket into the receptacle formed by the
junction of the cone and cylindrical jacket as aforesaid and then out of the spout
fixed to the cylindrical jacket just above the said junction.
A gas reservoir containing a number of Brays burners is situated in the lower
part of the apparatus, such that the products of combustion pass upwards through
the cone into the interior of the corrugated cylinder, then through the perforations:
of same and bossed plate into the flue pipe which is attached to the top of the
apparatus.
A gas cock is connected to the gas reservoir by a short tube.
The gas and water cocks are fixed to the cylindrical jacket in such a manner
that the spanner or key of the water cock rests against that of the gas cock, prevent-
ing the gas cock being turned on until the water cock is turned on, similarly when
the apparatus is in action, the gas key rests against the water key preventing the
water cock being turned off until the gas cock is turned off.
The gas key is shaped as indicated on Figs. 2 & 3 so that when the gas and
water keys are opened full, the water key can be partially turned back, thus
enabling the operator to obtain water at a high temperature.
For the purpose of this invention and as shewn on the annexed drawings of
which Fig. 1 is the sectional elevation of my improved water heater, and Figs. 2
and 3 are perspective views of the arrangement of the gas and water cocks when
out of and in action respectively, I construct a hollow corrugated cylinder A, which

page_text: stands vertically within a cylindrical casing or jacket B. The top face of said.
corrugated cylinder A is convex and the lower edge rests upon the outer surface
of a hollow frustum of a cone C which spreads to its base to the diameter of the
cylindrical jacket B, this junction forming the water receptacle.
The corrugated cylinder A is perforated by a number of holes near its lower edge
and a few holes near its top, and above it is a convex bossed plate D, fixed in a
groove round the cylindrical jacket B. The said bossed plate D being perforated
by a hole in its centre and a number of slots near its outer edge.
A pipe E projecting over the bossed plate D leads from a water cock F and
a spout G is fixed to the cylindrical jacket B, just above the junction of the cone C
and cylindrical jacket B.
A gas reservoir H containing a number of burners K is situated in the lower
part of the apparatus and a tube J is connected to it which leads from a gas cock L.
The gas cock L and water cock F are fixed to the cylindrical jacket B in such
a manner that when the apparatus is not in action the spanner or key M of the
water cock F rests against the spanner or key P of the gas cock L, so that the
operator to obtain hot water must first turn the key M of the water cock F, before
he can turn the key P of the gas cock L, again, when the apparatus is in action
the gas key P rests against the water key M and the operator to close the water
and gas ways must first turn the gas key P to close the gas way before he can turn
the water key M. to close the water way.
The gas key P is shaped as indicated on Figs. 2 & 3 so that when the gas and
water cocks L and F are opened full the water key can be partially turned back
thus enabling the operator to obtain water at a high temperature.
The water course through the apparatus is as follows: When the operator
turns on the key M, the way is opened for the water which passes through the
water cock Fand the pipe E. It then flows upon the bossed plate D and issuing
through the perforations of same, streams down the sides of the corrugated cylinder Ä
and cylindrical jacket B into the receptacle formed by the junction of the cone C
and the cylindrical jacket B and then rises to the level of the spout G and flows
out of same at any degree of temperature up to boiling according to the degree
of opening the gas and water cocks.
The products of combustion from the burners K, pass upwards through the
cone C into the interior of the corrugated cylinder A, then through the perfora-
tions of same, passing upwards between the corrugated cylinder A and cylindrical
jacket B and through the slots in the bossed plate D to the flue pipe R which is
attached to the top of the apparatus to carry away the superfluous products of
combustion.
The heated products of combustion in coursing through the apparatus are taken
up by the water streaming down the sides of the corrugated cylinder A and
cylindrical jacket B. The heat being imparted to the water and the superfluous
products of combustion passing through the flue pipe comparatively cold.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improvements in water heating apparatus consisting of the arrangement
of the gas and water cocks wherein the keys or spanners are so shaped and fixed
relatively to one another that the gas key cannot be turned to open the gas cock
until the water key has been turned to open the water cock and the water key can-
not be turned to close the water cock until the gas key has been turned to close the
gas cock, for the purpose herein set forth and illustrated.
2. The improvements in water heating apparatus consisting of a hollow per-
forated corrugated cylinder A with convex top and made to rest upon a hollow
frustum of a cone C affixed to a cylindrical jacket B, and a perforated bossed
plate D for the purpose herein set forth and illustrated.
3. The improvements in water heating apparatus consisting of the combination
