Improvements in Instantaneous Water Heaters.
I, WILLIAM JOHN RIGHTON, of 376 Euston Road, in the County of London, Zinc
Worker, do hereby declare the nature of this invention to be as follows:-
-
My invention relates to an apparatus for the purpose of instantaneously heating
water, by the operation of the heat produced from the combustion of gas from
perforated tubes bent at the outer ends, situated at the base of the apparatus. The
heating products passing upwards, and through openings in and between a number
of corrugated cylinders, each of these cylinders sliding one into the other, and
held rigid by projecting pieces of metal sliding down the corrugations of the outer
cylinder, in any desired position. At the top I fit a lid or cover formed in the
shape of a reservoir, with a series of small perforations, and to each pair of holes
I drop a staple shape piece of wire for the purpose of spreading the cold water
from the supply as it passes through the aforesaid holes on to the corrugations in
the cylinders. In the centre of the said lid or cover I construct a perforated well
to fit inside and down into the centre cylinder, to permit the heating products
after it has travelled up and down and through the slots in the cylinders, and
when exhausted out by the perforations in the well. The fine sprays of cold water
flow down the corrugations of the cylinders and thereby become heated to a high
temperature by the time the water falls into the cistern at the base.
The object of my invention is to produce an apparatus by the combustion of gas
to give a continuous supply of water at a high temperature of heat, for the purpose
of supplying hot water to baths, or any other like purpose.
My invention is constructed with a cylindrical corrugated metal frame with one
or more slotted corrugated cylinders to slide down the inside of each other, with
pieces of metal rivetted in various positions to keep the whole rigid. At the base
I form an open conical shaped cistern with the outflow pipe projecting up in the
cistern and down on the centre gas supply pipe, for the purpose of the heated
water passing from the cistern down the pipe into a movable reservoir beneath the
burner tubes, and to escape into the bath from an outflow pipe fixed in the said
reservoir.
At the top I fit a reservoir lid or cover, with a series of small perforations with the
staple shaped pieces of wire, and the perforated well as herein before described.
If preferable I may construct my apparatus with cylinders with the slots or
openings, or the centre perforated well, and to place the inner cylinders in any
other position, such as an example :-I may form a centre corrugated cone attached
to the lid, and another cylinder resting on the top of the cistern, and open at the
top to permit the heat to travel up to the top, down again, and to exhaust itself
by passing through and out by the centre corrugated cone at the top.
The supply of gas at the base of the cistern is regulated by the cold water
supply passing through a valve and thereby lifts a gas valve by an arrangement
beneath to permit gas to supply itself to the burner when the cold water is turned
on; but directly the cold water supply is turned off the gas valve drops and cuts
off the supply of gas.
The mechanism for the aforesaid performance is constructed in a perpendicular
cylindrical tube attached between the cold water supply valve, and the gas cock
for the purpose herein described.

Improvements in Instantaneous Water Heaters.
1, WILLIAM JOHN RIGHTON, Zinc Worker, of 376 Euston Road, in the County 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 -
My invention relates to an apparatus for the purpose of instantaneously heating
water, by the operation of the heat produced from the combustion of gas, through
perforated tubes bent at the outer ends, situated at the base of the apparatus.
The heating products passing upwards, and through openings in and between a
number of corrugated or plain cylinders, each of these cylinders sliding one into
the other, and held rigid by projecting pieces of metal sliding down the corrugations
of the outer cylinder, in any desired position. At the top I fit a lid or cover formed
in the shape of a reservoir, with a series of small perforations, and to each pair of holes
I drop a staple shape piece of wire (or otherwise), for the purpose of spreading the cold
water from the supply as it passes through the aforesaid holes on to the corrugations
or sides of the cylinders. In the centre of the said lid or cover I construct a perforated
well to fit inside and down into the centre cylinder, to permit the heating products
after it has travelled up and down, and through the slots in the cylinders, and when
exhausted out by the perforations in the well; or these perforations may be omitted.
The fine sprays of cold water flow down the corrugations of the cylinders and thereby
become heated to a high temperature by the time the water falls into the cistern at
the base.
The object of my invention is to produce an apparatus by the combustion of gas to
give a continuous supply of water at a high temperature of heat, for the purpose of
supplying hot water to baths, or any other like purpose.
My invention is constructed with a cylindrical corrugated metal frame with one or
more slotted plain or corrugated cylinders to slide down the inside of each other, with
pieces of metal rivetted in various positions to keep the whole rigid. At the base I
form an open conical shaped cistern with the outflow pipe projecting up in the cistern
and down into a movable reservoir beneath, or to escape into the bath by a projecting
outlet from the cistern.
At the top I fit a reservoir lid, or cover, with a series of small perforations, with or
without the staple shaped pieces of wire, and the perforated well as herein before
described.
If preferable 1 may construct my apparatus with cylinders having slots, or openings;
or the centre perforated well, and to place the inner cylinders in any other position,
such as an example :-I may form a centre corrugated cylinder attached to the lid,
and another cylinder resting on the top of the cistern, and open at the top to permit
the heat to travel up to the top, down again, and to exhaust itself by passing through
and out by the centre corrugated cone at the top.
The supply of gas at the base of the cistern may be regulated by the cold water
supply passing through a valve and thereby lifts a gas valve by an arrangement beneath,
to permit gas to supply itself to the burner when the cold water is turned on; but
directly the cold water supply is turned off the gas valve drops and cuts off the supply
of gas. The mechanism for the aforesaid performance is constructed in a perpendicular
cylindrical tube attached between the cold water supply valve, and the gas cock
according to the patent granted to me No. 18682, bearing date December 21, 1888, for
the purpose herein described.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof reference being had to letters and figure
marked thereon.
Figure 1 represents the apparatus one half in elevation and the remainder in vertica
section. Figure 2 is a plan on line A, B. Figure 3 is a plan on line C, D. Figure

page_text: I carry out my invention as shown in Figures 1 to 5 in the following manner :-
For the base I construct a plain metallic cylinder m, with an open conical cistern t,
mounted on three legs. In the inside of the cylinder I fit a gas tube q with burners r,
jutting out on each side with the ends turned downwards into the conical cistern t;
and to the tube q, I connect a gas cock p with a jet o which operates when the handle n
is slightly turned on in order to supply gas to the jet o, and when alight is passed into

tion, and in what manner the same is to be performed, 1 declare that what I
