Improvements in Heat Radiators or Reflectors for Gas, Oil, and other
Stoves.
I ALFRED DAVID SMITH of 30 College Road Walthamstow in the County of
Essex, Commercial Clerk, do hereby declare the nature of this invention to be as
follows:-
My invention relates to heat radiators or reflectors adapted specially for use on
or in connection with gas oil or other stoves, with the object of deflecting the heat
arising from the stove in any desired direction.
It consists essentially in the use and arrangement of one or more deflectors in
such a manner upon the stove as to receive and radiate the hot air ascending there-
from in whatever direction or directions may be required, and at the same time to
prevent loss of heat by the escape of hot air through the flue or otherwise without
useful effect.
In carrying out my invention I propose to place upon or attach to the upper end
of the chimney or flue of a stove a horizontal flange or plate of metal or other
suitable material, having an opening formed in it corresponding to that of the flue.
Attached to or formed in one piece with the horizontal plate, and preferably at an
acute angle thereto, I provide a deffector for the purpose of directing the hot air as
required, the space included by the angle of the two surfaces being closed in at the
sides by metal or other suitable plates.
In operation the radiator having been fixed upon the upper end of the flue or
chimney, and the stove being in use, the hot air rises through the flue or chimney
and passing through the openings formed in the bottom of the radiator impinges
upon the deflector, whereby it is thrown out of its vertical course into a direction
varying according to the angular inclination of the deflector to the radiator.
By another arrangement I may cause the hot air to be deflected in two different
directions at the same time. To effect this the sides of the horizontal plate are
bent up vertically, the deflectors which are placed between the vertical sides being
made either in one piece bent across the centre at a suitable angle, or in two equal
parts attached together in a V-form by a hinge or other joint, and arranged in
position with the angle or joint approximately over the centre of the flue, for the
purpose of diffusing the heat in different directions.
By this arrangement the hot air passing up the flue and through the openings
formed in the radiator is received and concentrated between the side plates and the
deflectors, whereby it is diffused with its maximum effect in the radial directions
determined by the angular inclination of the deflector to the horizontal plate or
radiator.
I may adapt my improved radiator to the existing forms of radiators by inserting
one or more inclined surfaces within the air-chamber whereby the heat would be
diffused into the apartment in any desired direction or I may construct my radiator
in the shape or form of an inverted cone for this purpose.

I, ALFRED DAVID SMITH, of Elswick, Banchovy Road, Blackheath, in the
County of Kent, late of 30 College Road, Walthamstow, in the County of Essex,
Commercial Clerk, 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 invention relates to heat-radiators or reflectors adapted specially for use on
or connected with gas, oil or other stoves, with the object of deflecting the heat
arising from the stove in any desired directions.
It consists essentially in the use and arrangement of one or more deflectors in
such a manner upon the stove as to receive and.radiate the hot air ascending there-
from in whatever direction or directions may be required, and at the same time to
prevent loss of heat by the escape of hot air through the flue or otherwise without
useful effect.
In order that my invention may be more clearly understood reference is had to
the accompanying drawings illustrating my invention, upon which
Figure 1 is a perspective view of one form of my improved radiator applied to an
oil stove Figure 2 being a modification of the same.
Figure 3 shews the radiator arranged in the form of an inverted cone, and
Figure 4 illustrates a radiator arranged reversibly upon a pivotted spindle.
In carrying out.my invention I may place upon or attach to the upper end of the
chimney or flue of a stove, a horizontal flange or plate of metal or other suitable
material A provided with an opening B corresponding to that of the flue as shewn
on Figure 1. Attached to or formed in one piece with the horizontal plate A and
preferably at an acute angle thereto, I provide a flat or curved deflector C for the
purpose of directing the hot air as required, the angular space included between
the two surfaces A and C being closed in at the sides by metal or other suitable
plates A. The deflector C may be made reversible by mounting it upon a
horizontal spindle pivotted in the sides as shewn on Figure 4 in dotted lines.
In applying my invention to existing stoves I may arrange to dispense with the
horizontal flange or plate and avail myself of the existing grid, and I may also
arrange to pivot or hinge the deflector so that the heat may be deflected to either
side as may be desired.
In operation the radiator having been fixed upon the upper end of the stove or
chimney, and the stove being in use, the hot air rises through the 'flue or chimney
and passing through the openings formed in the bottom of the radiator impinges
upon the deflector C whereby it is thrown out of its vertical.course into a direction
varying according to the angular inclination of. the deflector C to the radiator.
By another arrangement shewn,on Fig. 21 may cause the hot air to be deflected
in two different directions at the same time.
To effect this the deflectors C are placed between the vertical sides A' being
made either in one piece bent across the centre at a suitable angle, or in two equal
parts attached together in a V-form by means of a hinge or other joint D, and
arranged in position with the angle or joint D approximately over the centre of
the flue for the purpose of deflecting the heat in different directions.
By this arrangement the hot air passing up the flue and through the openings
formed in the grid is received and concentrated between the side plates A', and the
deflectors C whereby it is diffused with its maximum effect in the radial directions
determined by the angular inclination of the deflector C to the grid or radiator.
I may adapt my improved radiator to the existing forms of radiators by inserting

page_text: one or more inclined surfaces, curved or otherwise, within the air chamber, whereby
the heat would be deflected throughout the apartment in any desired directions;
or I may construct my radiator as shewn on Figure 3, in the shape or form of an
inverted cone or dome E, for the same purpose.
In the application to a gas or other stove having no flue, the radiator may be
arranged on any part thereof conveniently situate for receiving and deflecting the
maximum of heat in the desired directions.
Having now particularly described and 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. A heat radiator for oil, gas, or other stoves, consisting of the arrangement of
a deflector Cupon and at an angular inclination to the top flange or grid of the
flue, as described with respect to Figure 1 of the accompanying drawings.
2. Heat radiators for stoves consisting of a rectangular or other case open at
front and back and having vertical or inclined sides, a V-shaped plate or double
deflector formed of two hinged or jointed, flat or curved plates, arranged between
the vertical sides, with the joint or angle situate approximately over the centre of
the flue, for the purpose specified and as shewn on Figure 2.
3. Heat radiators for stoves comprising a hinged or pivotted deflector capable of
turning between closed ends, arranged to fit upon the flue, as and for the purposes
described with reference to Figure 4 of the accompanying drawings.
4. Heat radiators for stoves constructed, combined and arranged as described
and for the purposes set forth.
