COMPLETE SPECIFICATION.
Improvements in Stoves.
I ARTHUR WYNDHAM MARTIN of Gorebrook House, Hyde Road, Gorton in
the County of Lancaster, Surgeon, 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:-
My said invention relates to improvements in the stoves described in the
Specification left with my application for a Patent No. 16122 of A.D. 1893 and
has for its object a stove of a simpler and cheaper construction than the one
described therein.
I find that when using a fuel receptacle perforated at the bottom and sides the
circulation of air between the cylindrical surface of the fire receptacle and the
casing of the furnace to some extent absorbs and minimises the radiant heat and
if a suitable air space is left between such a fuel receptacle and the casing it is
possible to largely prevent the overheating of the casing which by burning or
overheating the surrounding external air causes the unpleasant odour known as
burnt air usually encountered in stove heated apartments.
The accompanying drawing illustrates a stove made in accordance with my said
invention in which a is the external casing of the stove closed by a cover b which
may be hollow having a sand luted joint at 6'. c is a hollow base supported by
feet c'. The cover if hollow and the base may be perforated to enable air to
circulate therein. e is an ash tray having orifices e' for the admission of air which
is regulated by the sliding covers e. f is a diaphragm with an opening f¹ for the
admission of air to the interior of the stove and to allow ashes or dust to fall from
the bottom of the fuel receptacle to the ash tray. g is the fuel receptacle
perforated at the bottom and sides and having projections 92 near the top to keep
it central in the stove. h is the exit for the products of combustion. i is an air
chamber surrounding the fuel receptacle g. The air space is in my present
invention much greater than in my former one for the reason hereinbefore stated.
The exact capacity of this air chamber may be varied somewhat but in practice !
find that the best proportion between the diameter of the air chamber and that of
the fuel receptacle is that shown in the drawing.
The fuel receptacle rests on feet or projections y' on the diaphragm f. to allow
the air to freely circulate up the sides. In lieu of feet the base of the fuel
receptacle may have a projecting rim with parts cut away.
In some.cases an inner hinged lid k may be provided as in my former invention.
The supports k¹ for the lid k are not continuous round the casing in order that the
projections g of the fuel receptacle may pass.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I claim nothing described or claimed in the Specification left with my
application for a Patent No. 16122 of A.D. 1893 but 1 declare that what I
claim is,
In a stove the combination of the single casing a and the fuel receptacle o
perforated at the bottom and sides and surrounded by such an air circulating
snacs i as will materialle minimise the ection of the boat radiating from the fuel
