I, HERBERT JOHN DOWSING, of 24, Budge Row, Cannon Street, in the City of.
London, Electrical Engineer, do hereby declare the nature of this invention
to be as follows:-
In my Specifications No. 26249 of 1896 and 4786 of 1897 I have described
electric glow lamps applied for heating purposes, these being provided with
reflectors behind them inclined in such a manner as to reflect a large number of
the heat rays away from the lamps themselves. My present invention relates
to an electric stove in which arrangements of this kind are adopted.
1
On a base which is provided with switches and preferably contains safety
fuses I mount several electric glow lamps preferably having cylindrical glasses.
of considerable height and long filaments within them. Behind and at the sides
of these lamps, which are exposed in front I provide angular reflectors of the
kind above referred to and I cover the spaces behind them so that each angular
reflector with its back forms a triangular channel. Air ascending these channels
becomes heated and issuing from their upper ends is directed upwards and for-
wards by a sloping roof over the lamps.

I, HERBERT JOHN DOWSING, of 24, Budge Row, Cannon Street, in the City of
London, Electrical 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:-
-
In my Specifications No. 26249 of 1896 and 4786 of 1897 I have described
electric glow lamps applied for heating purposes, these being provided with
reflectors behind them inclined in such a manner as to reflect a large number of
the heat rays away from the lamps themselves. My present invention relates
to an electric stove in which arrangements of this kind are adopted as I shall
describe referring to the accompanying drawings.
Fig. 1 is a front view, Fig. 2 is a central vertical section and Fig. 3 is a
sectional plan on the line A A of Fig. 1.
On a base a having suitable sockets projecting from its upper side are fixed
several electric glow lamps b. Of these four are shewn in the drawing but

page_text: obviously there may be a greater or less number. They are preferably of elon-
gated shape containing long filament loops c...
-
The base a may contain safety fuses, and it has switches by which any one
of the lamps can be excluded from the circuit: Behind the range of lamps
there are arranged metallic reflectors d preferably of smooth bright copper which
as described in my previous specification are inclined at such angles that the
rays from any one of the lamps, are not reflected back on that lamp itself but are
distributed in a forward direction. Behind the range of reflectors d there is a
back e which with the reflectors form a number of vertical triangular channels f
which terminate a little below a sloping roof g. Air entering at the lower mouths
of these channels becomes heated as it ascends and issuing from the upper
mouths is deflected in a forward direction by the roof. Thus while heat is
radiated forwards from the lamps, and from the reflectors also, heated air is
directed forwards, so that the stove acts as if it were an open fire.
Obviously the design of the stove may be varied as desired. Thus the lamps
may be vertical and situated in a recess having ornamented sides like an ordinary
fire place, the lamps occupying the space usually occupied by the fire.
n
Having now particularly described and ascertained the nature of this
invention and in-what-manner-the-same is to be performed, I declare that what
I claim is-
An electric stove: consisting of, several elongated electric glow lamps situated
in front of inclined reflectors which, with a cover at the..back form triangular
channels-by-which-air-ascends becoming-heated_and_directed_forwards_by_ a
sloping roof substantially as described.
