Improvements in Instantaneous Water Heaters.
1, 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 or oils,
from one or more burners situated at the base of the apparatus. The heating
products passing upwards, between and around two cylindrical boilers; each of
these cylindrical boilers being connected together with a flat spiral tube, to permit
the heating products to travel in a spiral direction before it exhausts itself in its
action at the top of the said apparatus.
The cold water enters at the base of the outer cylindrical boiler, and rises to the
top of the said boiler and down a pipe into the spiral tube flowing downwards to
the bottom of the said tube; thence through a tube into the base of the inner
cylindrical boiler rising to the top and down a pipe and out by the outlet spout,
and thereby become heated to a high temperature by the time the water falls into
the bath or any other vessel.
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 and the like.
My invention is constructed with an inner and an outer cylindrical vessel con-
nected together by pipes and a flat spiral tube fixed between the two aforesaid
cylindrical vessels, in order to form a circulating boiler.
If the heat is produced from the combustion of gas, I attach to the apparatus a
gas valve box and water supply valve. To the gas valve box I connect a stop
cock with the usual connecting piece and union. At the top of the cock plug I fix
a small cock with tube which acts as a "pilot" light, and passed in through an opening
to ignite the various burners inside the apparatus. The gas valve is constructed
with a stop valve inside so as to regulate the supply; this said gas valve is con-
nected to a rod and the rod to a lever bar with a valve on the lever bar beneath
the water supply.
The lever is connected at the opening in the valve box by an india rubber tubular
hinge fixed to a projecting taper tube in the valve box and the lever by being
tightly secured by any ordinary binding material in order to prevent the water
passing into the gas valve.
The opening of the gas valve is regulated by the flow of water from the supply
valve forcing the valve on the end of the lever down and raising the gas valve
which permits a good supply of gas to pass into the burners; but when the water
fails or is turned off the gas valve closes thereby shutting off the gas to prevent the
base of the boiler from being destroyed by carbonising.
This apparatus may be used as a circulating boiler for the hot water to ascend
and in that case the hot water pipe would be connected to the top of the inner
cylindrical vessel.
It will be understood that the foregoing is given by way of illustration and
that the shapes, materials and parts may be varied in many ways within the scope
of my invention.

Improvements in Instantaneous Water Heaters.
1, WILLIAM JOHN RIGHTON, of 376 Euston Road, in the County of London,
Zinc Worker, 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 or oils,
from one or more burners situated at the base of the apparatus. Heating products
pass upwards, between two annular boilers; each of these annular boilers being
connected together with a flat spiral tube, to permit the heating products to travel
in a spiral direction.
The cold water enters at the base of the outer annular boiler, and rises to the
top of the said boiler and down a pipe into the spiral tube flowing downwards to
the bottom of the said tube; thence through a tube into the base of the inner
annular boiler rising to the top and down a pipe and out by the outlet spout heated
to a high temperature.
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 for the purpose of
supplying hot water to baths and the like.
I attain these objects by the illustrations in the accompanying drawing, in
which :-
Fig. 1 is an elevation of the apparatus ;
Fig. 2, is a transverse section of the gas valve, and a part of the water valve in
elevation;
Fig. 3, is a transverse section of the outer and inner annular boilers and the
spiral and other tubes to connect together the various parts in order to form a
circulating boiler. The arrows indicate the travel of the products of combustion.
Similar letters refer to similar parts throughout the views.
My invention is constructed with an annular vessel a and an inner annular
vessel d, connected together by a pipe e, a spiral flat tube f (fixed between the two
aforesaid annular vessels) and a tube h with a union g, in order to form the
circulating boiler. At the base of the annular vessel a I form the inlet i, and at
the top of the inner annular vessel d I fix a pipe c connected with outlet b. It is
preferred to illustrate this invention by the operation of the heat produced from
the combustion of gas from several burners fixed beneath the boiler at the base of
the apparatus, in connection with a gas valve box land a water valve s. To the
gas valve box I connect a stop cock v with the usual connecting piece and union t.
At the top of the plug I fix a small cock with tube u which acts as a pilot light, to
ignite the several burners inside the perforated cylinder. The gas valve box is
constructed at the base with circular shoulder k¹ and above the said shoulder rises
and falls the stop valve k. The valve k is connected to a rod m and the rod m to a
lever bar n, with a valve p beneath the water valve s. The lever n is connected
to the taper tube which projects from the valve box 1, by an india rubber tubular
hinge o, being secured by any ordinary binding material, in order to prevent the
water passing into the gas valve box l.
A cap is provided at the top of the valve box l.
The opening of the gas valve k is regulated by the flow of water from the
valves on the valve p on the end of the lever n so that the water as it passes
through the valve s. forces down the valve p and raises the valve k and permits a
good supply of gas to pass through the pipe into the burners; but when the
water fails or is turned off the valve k closes thereby shutting off the gas, to
prevent the base of the boiler from being burnt.
This apparatus may be used as a circulating boiler for the hot water to ascend

page_text: and in that case the hot water pipe would be connected to the top of the inner
annular vessel d. In this case any fuel may be consumed, either in a vessel, stove
or furnace, or the like.
It will be understood that the foregoing may be varied in many ways within the
scope of my invention.
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. In a circulating boiler, the combination of the annular vessels a and d, with
the pipes e and h, the flat spiral tube f, inlet i and outlet b, substantially as herein
described and according to Fig. 3, in the accompanying drawing.
2. In a regulating gas valve, the combination of the valve k, opening or
shoulder k¹, rod m lever n valve p with hinge o, valve box 1 and water valves,
substantially as herein described and according to Figs. 1, and 2, in the accom-
panying drawing.
