Metal Worker do hereby declare the nature of my invention for AN APPARATUS
FOR INSTANTANEOUSLY HEATING WATER to be as follows:-
I construct two cylindrical metal bodies of various diameters in such a manner as
to form a spiral water course from bottom to top of apparatus or I apply a grooved
perforated tray to allow small drops of water to run over outer side of inner
cylinder I also convey part of water to be heated from top of apparatus to
bottom by circular water troughs covered at tops varying in diameter and provided
with airholes the water is conveyed from one to another by tubes and into a disc
and finally into a perforated tray and down a spiral or plain conical body and
drawn off at bottom and is heated by gas jets fastened into a metal font or may
be heated by spirit oil or any artificial incans.

page_text: I WILLIAM JOHN RIGHTON of 376 Euston Road in the County of Middlesex
Metal Worker, do hereby declare the nature of my invention for "AN APPARATUS
FOR INSTANTANEOUSLY HEATING WATER" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement-
I construct an apparatus for instantaneously heating water with an outer casing
composed of two metal cylinders of different diameters one within the other and
with the space between formed into a spiral water course. The water to be heated
is supplied to the bottom of the spiral water course and passes from it at the top
into a circular covered water trough formed as a screw down which it flows to a
hollow disc shaped water chamber above the burners and then (it may be after
passing through another ring shaped covered chamber of larger diameter) it is
received into a hollow ring perforated at the bottom from which it flows on to and
trickles over the exterior of a conical metal chimney below which tho burners are
placed. The conical chimney is surrounded by a cylindrical casing of a diameter
equal to that of the base of the cone and the hollow ring covers over the space
between the top of the cone and the top of the cylinder.
The heated water passes off through an outlet pipe from the lower part of the
space between the conical chimney and the cylinder.
Preferably employ burners adapted for burning gas but burners adapted for
burning oil or spirit or other substance might be employed. When gas is used
I also so arrange the gas and water cocks that the gas cock cannot be turned fully
on unless the water supply cock has been previously opened.
In the Drawing hereunto annexed 1 have shewn the way in which I prefer to
construct the apparatus.
Figure 1 is a vertical section and Figure 2 a side elevation of the apparatus-
the other figures shew plan views of some of the various parts.
A is the outer water casing formed of two metal cylinders one within the
other and with the space between divided into a spiral water course by a spiral
division A as shewn at Figure 1. B is a cold water inlet cock by which water is
supplied to the bottom of the spiral water course. C is an outlet spout conducting
the water from the top of the spiral water course into a small well or funnel D at
the top of the covered water trough E-this trough as will be seen is made in the
form of an Archimedian screw. is a dome shaped water chamber into the upper
G. G. arc
part of which the water passes from the bottom of the screw trough E.
pipes by which the water is led away from the bottom of the chamber F and into
a ring shaped chamber H. F' is a division plate within the chamber F. The
central portion only of this plate is perforated as shewn at Figure 1-so that all
water passing from the upper to the lower compartment of the chamber F descends
on to the centre of the disc which forms the bottom of the chamber.
From the bottom of the chamber H the water passes by a series of pipes I into
a hollow ring J which is perforated at the botton. Through the perforations the
water is allowed to descend on to the exterior of a conical metal chimney K. which
is above the burners O, M is a cylindrical casing surrounding the chimney K-The
perforated ring J forms a cover to the space between this cylinder and the conical
chimney. -N is an outlet by which the heated water can flow away from the
bottom of the casing M.

page_text: If desired two or more such conical chimneys and cylindrical casings with hollow
annular chamber covering over the top of the space between the two may be used
one above the other.
In this case a chamber F may be placed in the centre of each chimney to
partially obstruct the upward passage of the heated gases from the burner through
the chimney and prevent them from rising upwards in a straight course.
0, 0, are gas burners carried by a hollow inetal font or box to which gas is
supplied through a gas cock P. This cock I place as shewn just below the water
cock and make the lever arm or key by which the plug of the water cock is turned
to come down in front of the arm of the gas cock when both cocks are closed so
that the gas cock cannot be opened until the water supply cock has been proviously
turned on. Q is a small bye pass or pilot cock which can be opened independently
of the water cock. When the heater is to be used gas should be turned on at this
cock and the gas lighted at the small nozzle Q which stands out from it, before
turning on the main gas cock. When the main gas cock is turned to turn on
the gas the lighted jet is by the turning of the cock brought into a position in
which the flame from it is projected through an opening in the sheet metal foot or
stand of the apparatus-so that the gas is ignited at the burners immediately that
gas is turned on to them.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
First. The construction of apparatus for heating water with an outor water
casing divided into a spiral water course substantially as described.
Second. The combination of an outer water casing and screw formed covered
trough through which tho water to be heated is caused to flow after it has been
passed upwards through the water casing.
Third. The coned or arched chamber with its perforated inner division plate Fi
to obstruct the heated gases from the burners from rising upwards in a straight
course.
Fourth. The conical chimney R with its cylindrical casing M and hollow annular
cover J perforated at the bottoin to allow water to trickle down from it on to the
conical chimney.
Fifth. The arrangement of the gas and water cocks substantially as described so
that the gas cock cannot be turned on without previously turning on the water
cock.
Sixth. The construction of apparatus for heating water substantially as herein
before described and illustrated in the Drawing annexed.
