Gas Lamps.
1 OSCAR SEEGRÜN of Berlin in the Kingdom of Germany do hereby declare the
nature of this invention to be as follows:-
The lamp burns with a downward flame and is supplied with air heated in manner
substantially as hereinafter described.
The Gas entering by a vertical pipe (to the under end of which the round or half
round burner is attached) passes through a cock or tap, below the tap a small reservoir
is placed composed of two conical parts into which the gas enters through several
small holes. This conical reservoir serves also as a reaction valve. When the pressure
of the gas within the pipe becomes too high the valve is lifted from its seat and the
opening for the passage of the gas is reduced.
The spherical or semispherical burner (made of steatite or other suitable fire proof
material) is provided with a horizontal row of small holes through which the gas
passes and is burned. Above the burner a cup or goblet is provided (within the pipe)
serving to reduce the pressure of the gas & also to catch the dust and soot contained
in the gas and thus preventing any obstruction in the holes of the burner.
The pipe with the burner is surrounded by two cylindrical compartments through
which the air passes to, the flame by vertical or horizontal tubes and in passing is
heated by the burning gas.

Gas Lamps.
! OSCAR SEEGRÜN of No. 64 St. Georges Road Warwick Square London in the
County of Middlesex 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 the class of Gas Lamps known as regenerative. A circular
case formed of one or more compartments comprise the body of the lamp to the under
side of which is attached the glass globe by flanges and suitable fastenings, through
the body of the lamp a supply pipe passes to the lower end of which is fixed the
burner which projects below a cylinder or open mouthed extension of the body of the
lamp, this cylinder is provided with a casing or formed entirely of fire proof material,
passing from top to bottom of the body are tubes open at their ends through which
the heated air passes from the burner, in the walls of the body holes are provided to
admit fresh air to the burner, by this arrangement the fresh air is heated before
reaching the flame resulting in a more complete combustion of the gas than would
otherwise be the case, to regulate the supply and pressure of gas. I place a
regulating chamber at a convenient position on the supply pipe the gas passes into
this chamber through a small opening and passage and through a larger opening into
a larger chamber and from thence into a smaller moveable chamber through small
holes therein any increase in the pressure of gas will act on this chamber raising it'
and with it two balls in such a manner that the openings through which the gas
passes are lessened in size and the pressure regulated.
In the accompanying drawings Fig. 1 is a sectional elevation of the lamp Fig.
vertical and horizontal section of the burner Fig. 3 a vertical section of the regulating
chambers and Fig. 4 a horizontal section of the body of the lamp on line ab (Fig. 1).
The same letters of reference referring to identical parts in all Figs. A is the supply
pipe through which the gas passes into the regulator through the small opening a and
thence through the larger opening to the enlarged chamber e from thence through
the small holes e into the moveable chamber d (the space shewn at is a receptacle
for dust or other impurities in the gas) any increase of pressure will cause the
chamber to rise and with it the two balls and has above described the gas now
passes to the burner B and the products of combustion and heated air passes off
through the tubes F the supply of air to the burner is through holes I in com-
partment G from thence through holes I' to compartments H thence through holes 111
to the open mouthed extension or cylinder E above the burner, the tubes F passing
through chambers G and H the heated air in them naturally warms the fresh air in
those compartments, the under part of the burner serves as a dust collector the
opening a closed by screw y is for cleaning purposes.

page_text: 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. In a regenerative gas lamp the round and flat burner B fixed on the under end
of pipe A in combination with the cylinder E and the vertical tubes F passing
through the compartments G and H and heating the air directed to the flame
through the holes I I' I".
2. The application of the regulator Fig. 3 with the. moveable tube d and the back.
stroke valves composed of the balls g and h.
