We, HENRY ALBERT GALLIERS and FREDERICK KLAERR both of Inkerman Street,
St. Kilda, in the Colony of Victoria, Plumbers and Gasfitters, do hereby declare the
nature of this invention to be as follows:-
This invention relates to that class of apparatus which is commonly used for heating
water in bath rooms. It is different to most of them in this, that the water comes
into direct contact with the heated air produced by the combustion of the gas, instead
of into indirect contact, through the medium of a metal plate, and it is different in
this also, that the gas is not mixed with atmospheric air prior to combustion, as it
is in the Bunsen burner now almost universally used for this purpose, but is burnt as
supplied by the gas company. We wish it understood however, that there is no
novelty in these two points of difference with the ordinary apparatus, but that we simply
call attention to them as a preliminary to explaining wherein the essence of our
invention lies, because we believe that the two peculiarities noticed cannot be
satisfactorily retained except by the use of that which forms the essence of our
invention. That essence lies in the use of wire gauze preferably in the form of
concentric tubes or cylinders down which the water to be heated trickles, meeting as
it falls, the upward current of heated air produced by the combustion of the gas at
the burners. There are other and subordinate improvements in our apparatus, but
this wire gauze is its most important novelty.

page_text: We HENRY ALBERT GALLIERS, and FREDERICK KLAERR, both of Inkerman Street,
St. Kilda, in the Colony of Victoria, Plumbers and Gasfitters, 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 relates to that class of apparatus which is commonly used for heating
water in bath-rooms. It is different from most of them in this that the water comes
into direct contact with the heated air produced by the combustion of the gas instead
of into indirect contact, through the medium of a metal plate, and it is different in this
also that the gas is not mixed with atmospheric air prior to combustion as it is in the
Bunsen burner now almost universally used for this purpose but is burnt as supplied
by the gas company. We wish it understood however that there is no novelty in these
two points of difference from the ordinary apparatus but that we simply call attention
to them as a preliminary to explain wherein the essence of our invention lies because
we believe that the two peculiarities noticed cannot be satisfactorily retained.except
by the use of that which forms the essence of our invention. That essence lies in the
use of wire gauze preferably in the form of concentric tubes or. cylinders down which
the water to be heated trickles, meeting as it falls the upward current of heated air
produced by the combustion of the gas at the burners. There are other and
subordinate improvements in our apparatus, but this wire gauze is its most important
novelty.
We will now refer to our drawings in order to shew exactly how we make our
apparatus and how we prefer to apply the wire gauze.

invention.

In these Figures A A are the concentric gauze tubes made preferably of copper
wire and supported at their upper ends between the joints of the tapering rings A' as
shown in Figures 2 and d. Their lower only being souned bus the sorian of sino
2

page_text: the central one of which is supported on the lower screwed end of the central rod A³.
The outer upper tapering ring A' is soldered to the inner bottom edge of the water
receiving dish B which is furnished with a gauze bottom B¹ and an outer annular
chamber B2 from which the water enters the receiving dish through the holes B³ as
shewn Cand are the water pipes leading from the annular water jacket D which
surrounds the gauze tubes. The former of these pipes leads to the central dish and
the latter to the annular chamber. E is a conical shaped hood for leading the heated
water which drips from the outermost gauze tube to the annular chamber E' from
which the water overflows through the holes E on to the conical distributing dish E³
which leads the water to near the top edge of the fire box F³ thus filling the
lowermost hot water chamber F and from thence through the opening F into the
bath. Or if desired the hot water may be taken from it through tap F2. Above the
conical tube 3 which forms the fire box and inner surface of chamber F is placed the
dish G made preferably of copper. This dish has spouts G¹ leading from its side to
take the hot water dripping from the inner gauze tubes into the annular chamber E¹.
G are partitions crossing the conical hood E. H is the metal bottom of the apparatus
supported on the legs H. J is the gas supply cock leading to the transverse pipe J¹
into which are fitted the burners J2 as shewn in Figures 2 and 3, or such burners may
be formed with the branch pipes J leading from the central pipe J and such pipes
being furnished with burners Js as shewn in Figures 10 and 11. The plug of cock J
is fitted with the pilot light and cock J³ which is attached to the plug of the water
supply cock K the pipe K from which supplies the cold water to the annular water
jacket D as shewn. I is the cover for the top of the apparatus fitted with the central
knob L' which is made with a hole quite through it to allow the waste gases to pass
out from the apparatus.
In Figures 8 and 9 the alternative construction of the lower part of the water
heater is shewn and in this the annular chamber F descends quite to its bottom end so
as to form a water jacket over the whole surface of the fire box 3 and further a
pocket piece F is arranged over the aperture F¹ so as to retain the water around the
fire box at a high level.
The mode of operation is as follows:-The pilot light is first lit and then swung
into the apparatus over the burners J or J. The act of swinging in the pilot light
opens the gas supply and lights said burners and opens the water supply cock K so as
to supply cold water to the annular chamber D which fills. As it fills the water
becomes warm and flows upward through pipes C and C into the receiving dish B
from whence it passes through the gauze bottom B₁ which evenly distributes it over
the top ends of the gauze tubes A A whose ends being secured between the joints of
the wedge rings A' allow very fine apertures to lead the water to the gauze tubes down
which it trickles and is brought into direct contact with the heated air ascending
through the spaces between and around said gauze tubes. The water from the outer
tube is led to the annular chamber E' and from the inner tubes into the dish G from
which it is led by spouts G¹ to said chamber E. From the chamber E' it passes out
through holes E2 and flows down the conical plate E to near the top edge of the fire
box and into the annular chamber F from whence it passes out through the out-
flow opening F¹ into the bath. Or if preferred the hot water may be drawn off by the
tap F
"We would have it understood that we do not confine ourselves to the precise
manner herein described and explained for using the perforated gauze, as it may be
used in other forms besides that of tubes or cylinders nor do we confine ourselves to
the means set forth for supporting the top ends of such tubes, nor to the means for
supplying cold water and carrying away the hot.
Having now particularly described and ascertained the nature of our invention and
in what manner the same is to be performed we declare that what we claim is :-
First. The use of wire gauze preferably in the form of concentric tubes or cylinders
within a suitable casing in such a manner as that the water to be heated trickles down

page_text: the
gauze and is while trickling brought into direct contact with the heated air arising
from a gas burner at or near the bottom of the apparatus substantially as herein
described and explained.
Second. The combination of the outer water jacket D with the gauze tubes A
supported in their position by the parts marked A1 A2 A3 and B substantially as hercin
described.and explained and as illustrated in our drawings.
.
Third. The combination of the parts marked E, E¹ E2 E3 F F and G to G² forming
the final heating receiving chamber for the water substantially as herein described and
explained and as illustrated in our drawings.
