PROVISIONAL SPECIFICATION.
An Improved Apparatus for Expeditiously Heating and Boiling
Water.
I, WILLIAM AGGERS, of the City of Auckland, in the Colony of New Zealand,
Upholsterer, do hereby declare the nature of this invention to be as follows:-
The objects of my invention are to provide a portable and cheap apparatus for
expeditiously heating and boiling water, which at the same time is simple in con-
struction, occupies little space, is cleanly in use, and easily operated.
In order that the nature of my invention may be understood and for the purposes
of Provisional Protection I will now proceed to describe the same.
My apparatus consists principally of three parts.
First, when ordinary illuminating gas is used as the heating agent, a circular or
other suitably shaped gas burner which I prefer to be a Bunsen burner, or where
the said gas is not easily obtainable I use kerosene, methylated spirits, or other
suitable inflammable liquid and for this purpose provide a burner of novel construc-
tion. This latter burner is made preferably of cast iron and consists of a receptacle
and cover both of a circular shape. The said receptacle is divided radially into
equal alternate blank parts and chambers. These chambers are filled with asbestos
mineral cotton or other suitable non-combustible absorbent and thoroughly saturated
with an inflammable liquid. The said cover is provided with alternate openings
and blank parts corresponding with the chambers and blank parts of the receptacle
and is capable of revolving around a stud or pin provided for that purpose in the
center of the said receptacle and thus to regulate the flame by wholly or partially
uncovering the chambers. When the said chambers are wholly uncovered, the
cover is automatically raised by lugs provided for the purpose, thus admitting the
necessary amount of air to ensure perfect combustion.
The second part of my apparatus consists of an upper and lower receiver made
preferably of copper for containing the water to be heated. The upper receiver is
circular in form is fitted with a cover, and has a flue passing through its center,
which carries off the waste gases, and at the same time assists in heating the water.
The lower receiver is annular in form, but so constructed as to contain a small body of
At or
water while presenting a large heating surface to the flame from the burner.
near the top of this receiver is fixed a cock for the withdrawal of the heated water.
I sometimes find it advantageous to use more than one of these receivers and in that
case place them one inside the other. Immediately above the lower, and between
the said receivers I provide a flat cylindrical vessel furnished with transverse
passages through which the water from the upper receiver passes to the lower by
pipes provided for that purpose. This vessel is made preferably of copper and
slightly smaller in diameter than the lower receiver, thus leaving an annular space
for the exit of the heated gases to the flue in the receiver above. I also provide
pipes from the lower to the upper receiver for the escape of the steam generated,
and a pipe to allow the air to escape from the lower receiver when being charged.
The third part of my apparatus consists of an outer casing made of iron by
preference, of such form as entirely to surround the lower receiver and of a diameter
large enough. to leave an annular space around the same for the passage of the
heated gases to the flue. This casing, which is painted black outside to reduce
radiation of heat, also forms a support or stand for the upper and lower receivers,
and at its lower part is provided with legs, the spaces between which permit the

the apparatus are provided..

COMPLETE SPECIFICATION.
An Improved Apparatus for Expeditiously Heating and Boiling
Water.
I, WILLIAM AGGERS of the City of Auckland, in the Colony of New Zealand,
Upholsterer, 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 :-
I
The objects of my invention are to provide a portable and cheap apparatus for
expeditiously heating and boiling water, which at the same time is simple in con-
struction, occupies little space, is cleanly in use, and easily operated.
In order that my invention may be most easily understood I will now proceed to
describe the same, and for that purpose shall refer to the accompanying sheet of
drawings on which similar letters of reference indicate corresponding parts through-
out the several views.
Fig. 1, is a sectional elevation of my apparatus.
Fig. 2, is a section on the line 1-2 (Fig. 1).
Fig. 3, is a section on the line 3-4 (Fig. 1).
Fig. 4, is a view of the center part of the lamp on an enlarged scale.
Fig. 5, is a section on the line 5-6 (Fig. 4).
Fig. 6, is a plan of the lamp.
.
Fig. 7 is a section on the line 7-8 (Fig. 4).
'
My apparatus consists principally of three parts: First, when ordinary
illuminating gas is used as the heating agent, a circular or other suitably shaped
gas burner, which I prefer to be a Bunsen burner; or when the said gas is not
easily obtainable. I use kerosene, methylated spirits, or other suitable inflammable
liquid and for this purpose provide a lamp A. (Figs. 1, 4, 5, 6 & 7) of novel
construction.
.
This lamp A is made preferably of cast iron, and consists of a receptacle.a, and
cover a¹, both of a circular shape. The receptacle a, is provided at its upper part
· with a number of radial and equi-distant depressions or air channels a', thus forming
between them the radial flanged openings or apertures a. The vessel a, is
supplied with inflammable liquid through the aperture a' in a channel a³. The
apertures a, are filled with asbestos, mineral cotton, or other suitable absorbent
(as shewn in Fig: 5) the lower portion of which dips into and absorbs the liquid in
the vessel a. The said cover a', is provided with alternate openings and blank
parts corresponding with the apertures and depressions of the receptacle a, and is
capable of revolving round a stud or pin a³, provided for that purpose in the center
of the receptacle a, and thus of regulating the flame by wholly or partially
uncovering the apertures a*.
When the cover a', is revolved the apertures a, are uncovered and the said cover
is raised by sliding up the inclined faces of the lugs a", thus admitting the necessary
amount of air to the sides of the apertures a to ensure perfect combustion.
'
The second part of my apparatus consists of an upper receiver B and lower
receiver C-made preferably of copper, for containing the water to be heated. The
upper receiver B. is circular in form, is fitted with a cover b; and has a flue b¹,
passing through its center, which carries off the waste gases from the lamp A; and
at the same time forms heating surface for heating the water. The lower receiver C
is annular in form, but so constructed as to contain a small quantity of water while

page_text: presenting a large heating surface to the flame of the lamp A. At or near the top
of this receiver is fixed a cock c, for the withdrawal of the heated water.
I sometimes find it advantageous to use more than one of these receivers C, and
in that case place them one inside the other, leaving annular spaces for the passage
of the heated gases. Immediately above the lower receiver C, and between the
same and the upper receiver B, I provide a flat circular vessel D (Fig. 1 and
shewn by dotted lines in Fig. 2). This vessel D is furnished with transverse
passages dd, through which the water from the upper receiver B passes in a zig-zag
course to the lower receiver C. The said vessel D is made preferably of copper
and slightly smaller in diameter than the lower receiver C, thus leaving an annular
space for the exit of the heated gases.
I provide pipes c' c', from the lower receiver C to the upper receiver B for the
escape of the steam generated in the receiver C, and a pipe d', for the escape of
the steam from the vessel D. These pipes also allow the air to escape from the
several vessels when the apparatus is being charged with water.
The third part of my apparatus consists of an outer casing E made of iron (by
preference) of such form as entirely to surround the lower receiver C and of a
diameter large enough to leave an annular space around the same for the passage
of the heated gases to the flue. This casing which is painted black outside to
reduce the radiation of heat, also forms a support or stand for the upper receiver B
and lower receiver C, and its lower part is provided with perforations which
permit the admission of air to the lamp.
Suitable handles b, for conveniently lifting or carrying the apparatus are
provided.
In employing my apparatus for heating water the method of operating is as
follows:
The water to be heated is poured into the upper receiver B filling the vessels D
and C. The lamp A having been charged with kerosene or other suitable liquid, is
ignited. The heated gases pass inside and outside the vessel C as shewn by the
arrows, impinge on the vessel D, follow the direction of the arrows, impinge upon
the bottom of the receiver B and find an exit up the flue 61. The water in the
vessel C soon boils or becomes heated when it may be drawn off by the cock c³.
The withdrawn water is replaced by water from the receiver B circulating
through the strainer & backwards and forwards through the zig-zag passages d,
down the pipe c³, into the vessel C. By passing the water over this extended
heating surface it is heated or boiled in its passage from the receiver B to the
cock, and though the contents of the receiver B may be comparatively cool a
continuous supply of heated or boiling water may be obtained from the cock, as
long as the supply is maintained in the upper receiver B.
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 an apparatus for expeditiously heating and boiling water a vessel such as C
having supply pipe such as o³, & cock c³, substantially as and for the purposes
