Complete Specification Accepted, 23rd Nov., 1888
I ALFRED EVANS FLETCHER of No. 57 Gordon Square London in the county
of Middlesex Chemist, do hereby declare the nature of this invention to be as
follows:-
The object is to provide a stove to be used in heating air for warming buildings
and for other purposes where heated air is required such stove being so constructed as
to impart most of the heat generated by combustion to the air to be heated and so as
to effect uniform heating and be easily supplied with fuel.
A stove under my invention consists essentially of a combustion chamber sur-
mounted by a fuel container, an annular smoke and products of combustion uptake
surrounding the fuel container and an annular down-take for the air to be heated
surrounding the smoke and products of combustion uptake.
The combustion chamber is provided with a grate beneath which is an inlet for
air to support combustion. The fuel container has a charging door at or near the top.
The smoke and products of combustion uptake opens to the combustion chamber at
the bottom and to a smoke stack chimney or flue at the top.
The air heating annulus is made with an inlet way at the top and opens at the
bottom to an upcast delivery pipe or draught inducer leading to the spaces or
chambers to be heated.
The inflowing air to be heated is by preference filtered through a woollen cloth.

manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-

air to be heated is by preference filtered through a woollen cloth.
That my invention may be clearly and readily understood 1 have appended hereto
a vertical section of a stove illustrative of my invention. a combustion chamber

bustion uptake. d annular downtake for air. e fire grate. regulator for air to
support combustion. g charging door for fuel. smoke stack. i inlet for air to be
heated. jupcast for heated air leading to the spaces or chambers to be heated. The
arrows show the direction of the currents.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
