PROVISIONAL SPECIFICATION.
Improvements in Regenerative Gas Lamps.
I, JOSEPH DANISCHEVSKI of 116, Faubourg Poissonnièré, Paris, France,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to regenerative gas lamps and it has for its object to
dispense almost entirely with the regenerative chamber employed in this class of
lamp for heating the air and which usually occupies considerable space and being
opaque obstructs the light.
Reference is to be had to the accompanying drawings, forming part of this
Specification,
Figure 1 of which represents a central vertical section of my improved lamp.
Figures 2, 3, and 4 shew modified arrangements of the lamp.
In this improved lamp it will be seen that the usual regenerative chamber is
dispensed with, an air inlet a having a cover a' being provided in the hood c of the
chimney d which is made of transparent or translucid material, this air inlet pipe
being supported on the stem e rising from the burner tube to which it is attached
by screwing. The tube b is the gas-supply pipe the burner being between its upper
end and a cap carried by the stem e. The air inlet a leads through between the
double walls of a lenticular or other shaped metallic chamber which is also
supported upon stem and may be of simple or multiple arrangement the exterior
of which is licked by the flame for which it acts as a spreader, the incoming air
being thus heated.
An annular air passage g of scroll-like or tortuous cross-section with perforations,
admits air to the bowl which air becomes heated by contact with annulus g. The
latter may be replaced by the corrugated or gill-like ring shewn in Figure 3, the air
passing in the direction of the arrows becoming heated by the radiant heat. In
Figure 2 the air is heated in its passage between the outer shade H and the bowl G.
In this improved lamp, the air is sufficiently heated to produce a light equal to that
of any other regenerative gas lamp, the air inlets being so disposed that the flame is
surrounded on all sides.
I have indicated only the salient features of the lamp, as the details of construc-
tion may be varied; thus in Figure 2 the burner tube is enclosed by a perforated
casing for the admission of air. In this figure, A is the gas inlet pipe, B insulating
washers, C perforated air inlet casing, D point of emission of gas, E air inlet pipe,
Fair heater and flame spreader, G glass bowl. Several burners may be combined
in a single lamp so as to economically obtain a light of great intensity. Several
flame spreaders F may be superposed or combined in any manner.
In Figure 4, the burner tube instead of being a single tube, as in Figure 2, is
formed of two concentric tubes D' between which the gas passes to the burner, said
tubes being enclosed in a perforated casing containing gills I formed of corrugated
sheet metal, similar gills 1 being placed within the inner tube around the central
stem, both for the purpose of heating and regulating the air supply.
Dated this 1st day of November 1890.

Improvements in Regenerative Gas Lamps.
I, JOSEPH DANISCHEVSKI of 116, Faubourg Poissonniere, Paris, France,
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 gas lamps and it has for its object to dispense
almost entirely with the regenerative chamber employed in this class of lamp for
heating the air and which usually occupies considerable space and being opaque
obstructs the light.
Reference is to be had to the drawings accompanying the Provisional Specification
and forming part hereof:
Figure 1, of which represents a central vertical section of my improved lamp.
Figures 2, 3, and 4, shew modified arrangements of the lamp.
C
In this improved lamp it will be seen that the usual regenerative chamber is
dispensed with an air inlet a having a cover a being provided in the hood c of the
chimney which is made of transparent or translucid material this air inlet pipe
being supported on the stem e, rising from the burner tube to which it is attached
by screwing. The tube is the gas-supply pipe the burner being between its upper
end and a cap carried by the stem e. The air inlet a leads through between the
double walls of a lenticular or other shaped metallic chamber which is also
supported upon stem and may be of simple or multiple arrangement the exterior
of which is licked by the flame for which it acts as a spreader the incoming air
being thus heated.
In
An annular air passage of scroll-like or tortuous cross-section with perforations
• admits air to the bowl which air becomes heated by contact with annulus g. The
latter may be replaced by the corrugated or gill like ring shewn in Figure 3, the air
passing in the direction of the arrows becoming heated by the radiant heat.
Figure 2, the air is heated in its passage between the outer shade H and the bowl G.
In this improved lamp the air is sufficiently heated to produce a light equal to that
of any other regenerative gas lamp the air inlets being so disposed that the flame is
surrounded on all sides.
I have indicated only the salient features of the lamp as the details of construc-
tion may be varied; thus in Figure 2, the burner tube is enclosed by a perforated
casing for the admission of air. In this figure A is the gas inlet pipe B insulating
washers C. perforated air inlet casing D point of emission of gas, E. air inlet pipe,
F. air heater and flame spreader, G glass bowl; several burners may be combined
in a single lamp so as to economically obtain a light of great intensity.
Several
flame spreaders F may be superposed or combined in any manner. In Figure 4 the
burner tube instead of being a single tube as in Figure 2. is formed of two concentric
tubes D' between which the gas passes to the burner said tubes being enclosed in a
perforated casing containing gills I. formed of corrugated sheet metal similar gills I
being placed within the inner tube around the central stem both for the purpose of
heating and regulating the air supply.
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:
Constructing regenerative gas lamps substantially as set forth.
