COMPLETE SPECIFICATION.
New or Improved Gasifying Apparatus for Incandescence
Spirit Lamps.
.I, GUSTAV TRESENREUTER, of 15 Brunnenstrasse, Berlin, in the Empire of
Germany, 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 a gasifying apparatus for incandescence spirit lamps in
which the heat from the heating flame is communicated to the gasifying tube only,
the spirit reservoir remaining unaffected by such heat, and in which the heating
flame burns without smell and no special heating jacket is required.
The accompanying drawing represents a sectional elevation of a gasifying
apparatus constructed in accordance with my invention.
b is a gasifying tube the upper part of which is surrounded by a chamber a. The
lower part of the gasifying tube b, which contains the wick d, is fixed in the bottom e
of a cylinder g open at the top and connected with the spirit reservoir f by a screw
or otherwise. The cylinder 9 contains a pump h, the suction opening of which
passes through the bottom e of the cylinder g and is covered with a ball valve 2.
5 is the piston of the pump h, connected by a rod 3 to one end of a lever h4
and pressed constantly downwards by a spring 6. To the lower part of the
pump is connected a small pipe i which passes upwards through the cylinder g
and opens at its upper end into the lower part a¹ of the chamber a.
The chamber a is furnished with air holes a 2, and an injector k, the part of which
lying outside of the chamber a is furnished with air holes k 6, and is connected by
a small tube k2 with the upper end of the gasifying tube b. A tube 3 forms the
front part of the injector and opens into the ring k 4 surrounding the gasifying
tube b. The upper part of this ring is furnished with holes k 5.
The gasifying apparatus acts in the following manner. The outer arm of the
double lever 4 is pressed downwards, raising the piston / 5, and drawing spirit out
of the reservoir through the opening and past the valve 2 into the pump h.
The lever 4 is then released and the piston h5 is pressed downwards by its
spring h6 forcing the spirit out of the pump h up through the tube i into the lower
part al of the chamber a, where it is ignited and forms a starting flame which heats
the spirit that has been drawn up into the tube by b the wick d and commences the
vaporization of the said spirit. The chamber a thus serves as a cup for the spirit
from which the starting flame is produced.
When spirit vapour has been produced in the tube b, a part thereof passes through
the small pipe k 2 into the outer end of the injector k, through the nozzle thereof
into the tube k 3 and into the ring burner 4 drawing with it air through the
perforations k 6 of the injector. This mixture of air and vapour is ignited at
the holes k 5 by the flame of the spirit burning at a and then serves to maintain the
tube b at a proper heat for vapourizing the spirit supplied to it by the wick d.
The heating flame thus produced burns without smell because the combustion is
perfect by reason of the atmospheric air drawn in through the holes k 6 of the
injector.
The arrangement of the chamber a causes the heat radiating from the gasifying
flame burning at the holes k 5 to be thrown back upon the heating tube b and such
heat is not communicated to the spirit reservoir f which is further protected from
such heat by the part of the heating tube b which lies within the reservoir f being
surrounded by the cylinder o.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The gasifying apparatus for incandescence spirit lamps which consists of a
chamber a, a gasifying tube b, the lower part of which dipping into the spirit
reservoir is surrounded by a cylinder g, and a heating device composed of an
injector and perforated ring or burner k4 combined, arranged and operating,
substantially as described with reference to the accompanying drawing.
