Improvements in Incandescent Lamps for Burning Gasified Paraffin,
Volatile Hydrocarbons, and the like.
We, PAUL KINDERMANN, Manufacturer of 68 Möckernstrasse, JOSEF
BLUMENTHAL, Merchant of 20 Wilhelmstrasse both of Berlin Germany and
FRANZ WLACH Merchant of 13 Lorbeergasse, Vienna, Austria, do hereby
declare the nature of our invention and in what manner the same is performed
to be particularly described and ascertained in and by the following statement :-
The object of the present invention is to provide a lamp for burning gasified
paraffin, volatile hydrocarbons, or the like fluids and for producing light by means
of the incandescent bodies used in connection with incandescent gas lighting.
And in order to render the present Specification more easily intelligible reference
is had to the accompanying drawing which shows a lamp constructed according
to the invention in vertical section.
The body of the lamp A is provided at the top with a nozzle B over which
the burner is screwed or slipped. The nozzle B is provided with a cover a having
a very fine central perforation and with a sleeve a, extending downwards and
enclosing said fine perforation, said sleeve forming a guide for the rode having at its
upper end a needle point c adapted to extend into the perforation band to close
or regulate the opening of the plate a. The rode is bent round at its lower
end and provided with a hoss f having internal screw thread, into which a screw
spindle & fits, said spindle being prevented from axial movement in its bearing
in the body of the lamp, so that on turning the spindle the rod e will be raised
or lowered. The sleeve a is provided with perforations along its length so that
by varying the position of the rod e in the said sleeve, one, two or more of the
said openings will be laid free and allow more or less gas to pass into the sleeve
and through the opening or perforation b.
The burner which screwed or otherwise attached to the nozzle B consists of
the sleeve G having perforations g at its lower part through which the air passes
after the usual manner of a Bunsen burner. The top of the tube G is provided
with a conical closure cap D having perforations over the whole of its mantel,
and having a sieve, indicated by dotted lines E arranged behind such perforations.
In the crown of the conical closure D and extending downwards towards the
tube G is a spike h for the purpose hereinafter described. The suction wick L
for the fluid is arranged around the sleeve a in the manner shown in the
drawing, and suitable means are provided for pouring the fluid into the reservoir
or body of the lamp.
The device operates in the following manner :-
The fluid drawn up by the wick passes through the openings of the sleeve a
and is gasified by the heat of the burner, passes then through the perforation b
into the Bunsen burner tube G, where it is inixed with the requisite quantity of
air. The mixed air and gas pass upwardly through the sieve E and perforations
of the conical cap D where they are ignited and cause the incandescent body
placed over the cap to burn incandescently with an intense white glow.
The cap D and the spike h serve to absorb the heat produced at the burner and
conduct the same through the tube G to the plate. a of the nozzle B where it
serves to gasify the fluid being fed to the said nozzle by means of the wick L.
The amount of fluid gasified and the amount of gas fed to the burner may be
regulated by means of the needle point c.

page_text: Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is performed we declare that what we
-claim is :-
:-
In a lamp for burning gasified paraffin or other similar substances, such as
volatile hydrocarbons, the combination of a burner tube G suitably attached to the
body of the lamp and having air holes as specified, and a conical cap to said
burner, having its mantle perforated throughout, a sieve device arranged at the
back of said perforations, a spike in the crown of said cap extending downwardly,
a gasifying chamber under the burner tube G and means for transporting the
fluid from the reservoir of the lamp to said chamber substantially as described.
