Incandescent Gas Lamp.
I, RICHARD BEESE, Buildmaster, of 13, Gluckstrasse, Dresden, Saxonia,
Germany, 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 consists of a new and improved incandescent gas lamp in which
the flame burns from under so that the shadows cast by the frames of lamps, in
which the flame burns from above are eliminated and possessing other advantages
hereinafter set forth.
From the accompanying drawing, which shows a longitudinal section of a lamp
and forms a part of this specification it will be seen that I employ a gas leading
pipe a having on its end the nozzle d. The gas passing through said pipe and
nozzle enters a Bunsen tube e into which the air is lead by the cross tube f.
Hermetically secured to the said tube e is the burter h which latter has
integrally formed therewith a cylindrical depending closed collar r (as shown)
and which collar provided with a fluted end grips the end of a glass chimney or
cylinder m. Said collar is also provided with cross tubes h, similar to those
located in the Bunsen tube e aforesaid and through which air is directly conducted
to the flame.
The cylinder m carries a socket i which has one end bent upwardly and out-
wardly adapted to rest upon and grip the upper edge of the said cylinder, while
its lower end is perforated to allow the passage of the air to the flame and bent
inwardly forming a groove adapted to receive a ring p, to which latter is secured
the upper end of the stocking 1. The lamp is surrounded from the nozzle d to
the burner with a concentric body g in which the mouths of the said cross tubes
are fastened and which is secured at its lower end by a hermetical coupler o to a
glass bell-jar n. The burnt gases gathering in the bell-jar pass upwardly and
through the body g into a waste pipe 6 concentrically surrounding the supply
pipe a.
By this construction it will be seen that the air passing to the flame as also
that air lead into the Bunsen, tube is heated by the outward flow of the hot burnt
gases, while the incoming gas is also warmed by the same through the concentric
arrangement of the waste pipe about the gas leading pipe, thus giving great
essential advantages in the effectiveness as well as substantially reducing the
cost of the flame in addition to its freedom from shadows.
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:
1. An incandescent gas lamp having a downwardly burning Bunsen flame a
stocking in connection therewith, a glass cylinder surrounding the same, a glass
bell-jar enclosing said cylinder and being in air tight connection with a waste
nine for the burnt gases. substantially as described.

II. An incandescent lamp having a stocking, a ring secured to said stocking
and adapted to rest in a groove formed in the lower end of socket, said socket
having its upper end adapted to rest upon and grip the upper end of a glass
cylinder substantially as described.
III. An incandescent gas lamp having a Bunsen tube, fresh air supply pipes in
connection therewith and a waste pipe adapted to draw the burnt gases by and
around air pipes and heat the incoming air, substantially as described.
IV. An incandescent gas lamp having a supply pipe and a waste pipe con-
centrically arranged thereabout adapted thereby to heat the incoming gas sub-
stantially as described.
V. In an incandescent gas lamp the combination of a stocking 7 provided with
a ring 2, with the inwardly bent lower end of the socket i, as and for the purpose
specified.
