Improvements in Regenerative Gas Lamps.
I LÉON SOMZEÉ in care of Messrs. E. Bede & Co. of 37 Rue Philippe le Bon
Brussels, in the Kingdom of Belgium, Civil Engineer, do hereby, declare the nature
of this invention to be as follows:-
This invention relates to that class of gas lamp usually known as regenerative
lamps and consists in the following improved construction thereof. The improved
lamp differs from others in the more rational combinations of the different parts. It
is designed to possess a constant feed whatever the conditions of the surroundings.
The improved lamp is designed to stand higher temperatures than those of other
systems and consequently give better light.
The air feed is specially constructed to avoid disturbance by draughts and to pass
in one direction only, the movement of the gas and air feed being in contrary direction,
the combustion is not so rapid, and the luminosity increased. Each part which comes
under the influence of the heat of the flaine is constructed of cast iron of certain
thickness so that the temperature remains uniform and not be subject to sudden rise
or fall.
A further improvement consists in the device for preventing arrival of water or
foreign matter into the burner. In the improved lamp there is arranged in the gas
feed pipe a widened chamber in which the lower pipe embouches through a conical
nozzle with lateral openings as well as an opening above.
The interior parts of the lamp are made of enamelled cast iron adapted to with-
stand the effects of great and rapid variations of temperature. They comprise a
heater with inclined walls on which the products of combustion play before passing
to the chimney, and which terminates above in a cylindrical pipe. On the lower end
of the beater is an enamelled plate forming a reflector, and provided around its
periphery with a series of small holes by which part of the air passes into the globe
attached under said plate. A dome covers the heater resting on the said plate and
terminating above near the base of the chimney. The gas feed pipe passes down the
centre and is provided with the means, before described for preventing passage of
water etc. into the burner. It terminates below in a burner with radial orifices to
project the gas in a horizontal plane. The main portion of the air which has passed
the heater arrives through a cylindrical tube surrounding the burner and passes down
to the like through a double metallic gauze which covers the said air tube above the
burner.
The lower rim of the air tube forms the flame spreader and the double gauze has a
great influence on the quality of the flame.

Improvements in Regenerative Gas Lamps.
I LÉON SOMZEÉ in care of Messieurs E. Bede & Cie. of 37 Rue Philippe le Bon,
Brussels in the Kingdom of Belgium, 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 :—
This invention relates to that class of gas lamp usually known as regenerative
lamps and consists in the following improved construction thereof.
A regenerator with inclined walls terminating in a cylindrical tube integral there-
with, said tube having cast thereon an annular projector or guide for the flame for

page_text: circulation of heated air, said tube being closed by a double metallic gauze projecting
from the orifice; also in the combination with a generator of a plate of enamelled
iron having a series of holes in its periphery for passage of air into the globe and
carrying an exterior casing or dome integral with the chimney and leaning on an
annular support on said regenerator whereby the hot air is prevented from passing
direct into the chimney; also of a gas feed pipe cut in two parts connected by a
sleeve the upper part terminating below in a hollow conical enlargement the lower
part provided above with a projecting nozzle; and lastly the construction of the
essential parts of the lamp, subject to heat or exterior influence of cast iron enamelled
within and without.
Reference being made to the accompanying drawings in which Fig. 1 is a sectional
view of the lamp, Fig. 2 plan view of top of the regenerator and Fig. 3 an
elevation of the regenerator; the lamp comprises heater M with walls I on which
the products of combustion play before passing to the chimney and which terminates
below in a cylindrical_pipe D¹. On the lower end of the heater is an enamelled
plate H forming a reflector and provided around its periphery with a series of
small holes O by which part of the air passes into the globe attached under said
plate. A dome E integral with the chimney C covers the heater resting on the
said plate H and against the annular support N near the base of the chimney. The
gas feed pipe T passes down the centre and is provided with the sleeve M' for
preventing passage of water etc. into the burner. It terminates below in a burner B
of lance form as shown in the drawing. The flame projector D cast with the
cylinder D¹ is fed with heated air and is ring shaped. The flame receives therefore
the advantage of the radiation of heat from the projector so that the whole surface
of the flame is rendered active and the light thrown out in a horizontal plane.
The lower end of the tube D¹ is closed by a double metallic gauze which projects
somewhat from the orifice of the tube so as to fill up the space between the flame and
the edge of the projector.
This arrangement has a great influence on the quality of the flame.
The globe G supported on the annulus K is of the smallest size compatible with
the burning of the flame. Passages R allow of air passing from within the dome E
down to the interior of the cylindrical part D thence through the gauze to the
flame. The arrows show the movement of the gas and air 6 heing cold air, c gas,
d hot air.
The gas feed pipe may be protected from the heat by a covering of asbestos.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
In regenerative lamps.
1. A regenerator with inclined walls terminating in a cylindrical tube integral
therewith said tube having cast thereon an annular projector or guide for the flame
for circulation of heated air, said tube being closed by a double metallic gauze
projecting from the orifice.
2. The combination with a regenerator of a plate of enamelled iron having a series
of holes in its periphery for passage of air into the globe and carrying an exterior
casing or dome integral with the chimney and leaning on an annular support on said
regenerator whereby the hot air is prevented from passing direct into the chimney.
3: A gas feed pipe cut in two parts connected by a sleeve the upper part terminating
below in a hollow conical enlargement the lower part provided above with a pro-
jecting nozzle.
4. The method of constructing the essential parts of the lamp subject to heat or
