PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Water or other Fluid.
I, LEWIS WALKER LEEDS, of 20, Thurlow Hill, West Dulwich in the County
of Surrey, Heating and Ventilating Engineer, do hereby declare the nature of
this invention to be as follows :-
This invention relates to apparatus for rapidly heating water or other fluid.
The fluid receptacle is practically of distended bellows form which may be cast
in a single piece or may be made up of a central pipe opening into reversely
inclined surrounding discs joined at their circumferences. Such receptacle is
provided with inlet and disharge pipes and is partially surrounded by a firebrick or
other refractory covering or casing. The receptacle is heated by gas, or other
heating medium, but preferably by the use of ordinary flat flame gas burners
located below and between the discs the arrangement being such that the heat and
products of combustion pass up between the discs over the central core and part
way down on the other side before being allowed to escape. This arrangement
secures the utilization of a great portion of the heat and also forming a species
of heat chamber or casing in which the receptacle will remain warm for a
considerable period after the flame has been extinguished. Where necessary
baffle plates may be inserted in the line of flow or if preferred a coil formed of one
or more pipes may be employed in lien of the discs.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating Water or other Fluid.
I, LEWIS WALKER LEEDS formerly of 20, but now of 12 Thurlow Hill, West
Dulwich in the County of Surrey, Heating and Ventilating 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 relates to apparatus for rapidly heating water or other fluid.
The fluid receptacle is practically of distended bellows form which may be cast
in a single piece or may be made up of a central pipe opening into reversely inclined
surrounding discs joined at their circumferences. Such receptacle is provided with
inlet and discharge pipes and is partially surrounded by a firebrick or other
refractory covering or casing. The receptacle is heated by gas or other heating
medium, but preferably by the use of ordinary flat flame gas burners located below
and between the discs, the arrangement being such that the heat and products of
combustion pass up between the discs over the central core and part way down on
the other side before being allowed to escape. This arrangement secures the
utilization of a great portion of the heat, and also forms a species of heat
chamber or casing in which the receptacle will remain warm for a considerable
period after the flame has been extinguished.
Where necessary, baffle plates may be inserted in the line of flow or if
preferred a coil formed of one or more pipes may be employed in lieu of the

page_text: In order that the invention may be clearly understood reference is made to the
accompanying drawing in which:
Fig. 1 represents a longitudinal vertical section of a water or fluid heater
constructed according to this invention.
Fig. 2 is a cross sectional elevation on line in Fig. 1, and
Fig. 3 is a plan view partly in section and partly in elevation.
Within the casing A which is preferably of refractory material (such as fire
brick or the like, and which may carry fibres of asbestos if desired) is mounted the
inlet and discharge pipe B which in turn carries the heating discs or drums C through
which the fluid to be heated is caused to pass, as indicated by the arrows, any direct
flow through the tube B being prevented by means of the baffle plates & b mounted
on a small spindle d or otherwise secured in position. The apparatus is preferably
heated by means of ordinary flat flame gas burners e e supplied from pipe E, said
burners being located below and between the discs and well back in the apparatus,
so that the heat will to a great extent travel up and over the pipe B before
passing to the escape flue D, the opening to which is preferably near the bottom
line of the discs.
It will be evident that a coil of pipe somewhat after the style of a coil boiler
may be employed in the heat chamber instead of the discs but the latter construction
is preferred.
am of course aware that coil boilers of many forms are well known, and also
that solid heating discs mounted on a water pipe intended to be heated by gas have
also been employed, and I make no claim to coil boilers per se or to solid heating
discs, but
Having now particularly described as 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. The improvements in apparatus for heating water or other fluid consisting in
the combination with the refractory casing of the inlet and discharge pipe
surrounded by heating discs through which the fluid is caused to flow, and means
for heating same, substantially as described.
2. In water or other fluid heating apparatus the combination with means for
heating, of a pipe provided with baffle plates and carrying hollow heating discs
opening into said pipe, all substantially as set forth.
3. The improved apparatus for heating water or other fluid, substantially as set
forth.
