PROVISIONAL SPECIFICATION.
Improvements in or connected with Gas Heated Water Heaters or
Boilers.
I, EDMOND WALTER TYRRELL RICHMOND, of Academy Street, Warrington, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to water heaters or boilers heated by gas, and has for
its object, mainly to provide a construction of heater in which the heat shall be
efficiently employed, while, at the same time the container for the water to be heated
shall consist, mainly of a simple iron casting or vessel.
According to this invention, I combine or arrange in connection
with a gas heated oven, stove, or similar apparatus-say at the side or back-
a simple vessel or cistern of iron, preferably cast iron, in which the water is held
and heated, and having upon its bottom projections, pins or similar formations, on
which the gas jets play. The burner is disposed below the bottom of the vessel
or cistern, and below the burner is a fire-brick tile, or refractory material air being
admitted to the burner through suitable openings. Then up round the sides of the
water vessel or cistern, fire brick or refractory walls are carried, leaving a suitable
space between their inner surfaces, and the surface of the vessel or cistern; and
these spaces are in open communication with the flame or burner space below, and
the gases of combustion pass up within them all round the sides of the water vessel
or cistern, and thus, practically the whole vessel is enveloped with flame and heated
gases; rendering thereby the heated area large and efficient. The side walls
specified are enclosed in cast iron casings and held firmly in place thereby, and the
top of the gas spaces is enclosed in, and the vessel or cistern enclosed at the top by
a suitable cover.
The water vessel or cistern is made in different forms; and, in one arrangement,
is narrow as regards width, and extended out in the longitudinal direction, so as to
obtain large heating surface, compared with the volume of its contents. Also, in
some cases, it is provided with flow and return branches or pipes, where a circulating
arrangement of heating apparatus is required, and is provided-if necessary--with a
supply, regulated by a float or ball cock, or equivalent means.

Boilers.
I, EDMOND WALTER TYRRELL RICHMOND, of Academy Street, Warrington, in the
County of Lancaster, 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 reference to water heaters or boilers heated by gas, and has
for its object, mainly, to provide a construction of heater in which the heat shall be
efficiently employed, while, at the same time, the container for the water to be heated
shall consist, mainly, of a simple iron vessel.
According to this invention, I combine or arrange in connection with a gas heated
oven, stove, or similar apparatus-say at the side or back-a simple vessel or cistern
of iron, preferably cast iron, in which the water is held and heated, and having upon
its bottom, projections, pins, or similar formations, on which the gas jets play. The
burner is disposed below the bottom of the vessel or cistern, and below the burner
is a fire-brick tile,. or refractory material, air being admitted to the burner through
suitable openings. Then up round the sides of the water vessel or cistern, fire
brick or refractory walls are carried, leaving a suitable space between their iuner
surfaces, and the surface of the vessel or cistern; and these, spaces are in open
coinmunication with the flame or burner space below, and the gases of combustion
pass up within them all round the sides of the water vessel or cistern; and thus,
practically, the whole vessel is enveloped with flame and heated gases; rendering
thereby the heated area large and efficient. The side walls specified are enclosed
in a cast iron casing and held firmly in place thereby, and the top of the gas
spaces is closed in; and the vessel or cistern is enclosed at the top by a suitable
cover.
The water vessel or cistern is made in different forms; and, in one arrangement
is narrow as regards width, and extended out in the longitudinal direction, so as to
obtain large heating surface, compared with the volume of its contents. Also,
in some
cases, it is provided with flow and return branches or pipes, where
a circulating arrangement of heating apparatus is required, and is provided-
if necessary with a supply, regulated by a float or ball cock, or equivalent
means.
An apparatus according to this invention, is shewn in the annexed drawings in
Figures 1 and 2 in longitudinal and cross section respectively.
In the drawings a represents the metal of the side of any ordinary form of gas-fire,
or stove, to which the water heater referred to is applied. b is the cast iron casing in
which the cistern or water vessel is fitted and supported, this casing being cast or
fitted on to the body a. c is the open cistern or water vessel, having flanges c¹
which close the gas heating space at the top. The cistern has pins c² on its bottom,
on which the gas flames of the heating burner impinge; and a cover c³ closes or fits
over the top of the vessel c.
d is the fire brick or the refractory walls, carried up along the sides and ends,
and over the bottom of the casing b; and e represent the spaces upon which the
heating gases pass. f is the gas burner, which is introduced into the casing b
through an aperture 6¹ in front, which opening admits air to it; and h is a ball-cock
for supplying the cistern cwith water, and i the tap below for drawing off hot water
from it. are apertures at the upper edge of the sides of the casing b for the outlet
of dead gases.
The operation will be seen from the drawing, namely, the flames of the gas

C, and
use at once, at will) first impinge on the pins c² and bottom of the cistern
then pass up through the heating spaces e, between the cistern metal or body
and fire brick linings d, and thence out at the top through the openings. k.
In case of the gas heated boiler or heater described being employed as a separate
thing, the case b, of course, would be without any connections at the side, and
would rest on a suitable support.
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 :-
or
1. The herein described improvement connected with gas heated boilers
heaters, consisting of a cistern or vessel, as c, having a gas burner f below, and
fire brick or refractory walls d around its sides and ends, with a gas space between
the said vessel and walls, and a casing benclosing and carrying said walls and
burner; substantially as and for the purposes set forth.
2. The gas heated water boiler or heater consisting of the parts, and arranged
and adapted to act as shewn in and set forth with reference to the drawings.
