PROVISIONAL SPECIFICATION.
Improvements in Regenerative Gas Stoves.
I, FREDERICK SIEMENS, of No. 10, Queen Anne's Gate, Westminster, in the
County of London, Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to regenerative stoves suitable for warming apartments, in
which gas is consumed in open flames supplied with heated air, but these flames are
concealed so as not to hurt or annoy the eye by their great brilliancy while the
heat radiated from them is reflected into the apartment. I provide a concave
reflector, preferably of polished copper having its surface corrugated, and near the
upper part of this reflector, I place a horizontal gas pipe from which gas issues by
small horizontal tubes forming a flame or series of flames under a horizontal
reflecting plate. The products of combustion pass up in front of the edge of this
plate, behind a downwardly projecting flange which conceals the flame, and then
they descend behind a fresh air passage which is formed behind the reflector, after
which they ascend again to a chimney. The fresh air, entering at the lower part
of the passage behind the reflector, becomes heated as it ascends, and goes in a
highly heated condition to supply the gas flames, causing very complete combustion
of the gas and the evolution of great heat which is reflected into the apartment.
Air passages may be formed behind or at the sides of the channels for the products
of combustion, so that, by conduction from them, air may be heated for supplying
the apartment or for being led to other apartments.
Dated this 6th day of April 1891.

COMPLETE SPECIFICATION.
Improvements in Regenerative Gas Stoves.
I, FREDERICK SIEMENS, of No. 10 Queen Anne's Gate, Westminster, in the
County of London, 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:-
My invention relates to regenerative stoves suitable for warming apartments,
in which gas is consumed in open flames supplied with heated air, but these flames
are preferably concealed so as not to hurt or annoy the eye by their great brilliancy,
while the heat radiated from them is reflected into the apartment, as I shall
describe referring to the accompanying drawings.
Figs. 1 and 2 are vertical sections, on planes at right angles to each other, of
one form of regenerative. gas stove according to my invention;
Figs. 3 and 4 are similar sections of a stove with extended air heating flue
surface.
A is a horizontal gas pipe, which may extend across the whole width of the stove,
as shewn in the drawings, and which has projecting from it a number of small tubes
forming a flame or a row of flames directed horizontally or nearly so under a
plate B. The products of combustion pass up in front of the edge of the
plate B and behind or downwardly projecting flange C which, as shewn, may
conceal the flames preventing them from being seen in front of the stove, or
which may be arranged with glass, ceramic material or mica to transmit more or
less of the light. The products of combustion pass over the plate B, then descend
D:631

page_text: a passage D and ascend E, as indicated by the arrows, and proceed to a chimney
Alue F, either directly as shewn in Figures 1 and 2, or after passing through a helical
flue Gas shewn in Figures 3 and 4.
In front of the passages. D E is fixed a concave reflector H, preferably of
corrugated..copper polished, so that light and heat radiated from the flames above
are reflected by it into the apartment. Fresh air, entering by apertures K at the
bottom, ascends within the stove becoming heated by contact with the external
surfaces of the flue D, and the internal surface of the reflector H. The air
thus heated passes through openings LL' to supply the flame on its upper side,
the lower side of the flame receiving a supply of air more or less heated by
ascending in front of the reflector H. Fresh air also enters by apertures Kat
the hottom and, ascending within the stove, becomes heated by contact with the
flue E, and issues into the chamber through apertures M in the upper part of the
stove. In the form of stove shewn in Figures 3 and 4, besides the air heated in
the lower part, additional air entering the upper part by some of the perforations M
above a partition P is heated by passing along the surface of the helical flue G
and issues by apertures N or by an opening O at the top of the stove. W is a
trough for water to supply vapour for moistening the heated air, and a similar
trough may be arranged in connection with the form of stove shewn in Figures 1
and 2.
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 :-
A regenerative gas stove in which light and heat radiated from open gas flames
are reflected, and air is heated by contact with the surfaces of the reflector and
passages for the products of combustion, part of this air going to supply the flames,
substantially as described with reference to the accompanying drawings..
