COMPLETE SPECIFICATION.
New or Improved Spirit Burner for Heating Purposes.
I, EDUARD LENT, of 3 Lebuser Strasse, Berlin, in the Empire of Germany,
Mechanician, do hereby declare the nature of the said 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 spirit burner for heating purposes the management of
which is very simple, and in which the flame is easily regulated.
The annexed drawing is a vertical section of a spirit burner constructed in
accordance with the invention.
a is a tripod, at about the middle of the height of which is fixed a ring-shaped
channel which serves as a reservoir for the spirit intended to be vapourized.
This reservoir is furnished with an opening (normally closed by a cover or plug c)
for the introduction of the spirit. At any convenient part of the circumference of
the reservoir b, and communicating therewith by a suitable passage is placed a short
tube d in which is arranged a regulating screw f the lower end of which is shaped
as a conical valve which fits against a seating in the lower end of the tube d, and
thereby closes, when desired, a small channel g leading therefrom to the vapourizing
chamber h. By opening or closing this conical valve more or less the passage of
spirit to the vaporizing chamber h can be regulated with great ease. The
vaporizing chamber his traversed by a tube i which supports at its lower end a
dish k, and is or may be furnished with one or more air openings 1.
The chamber is provided at its upper end with several fine perforations or
slits m which serve as burner openings for vapour produced from the spirit in the
chamber h. The bottom of this chamber has also a small opening to allow spirit
to pass, from the chamber h to the dish k.
The apparatus is used as follows:-
To commence the vaporization of the spirit the screw fis raised high enough to
allow sufficient spirit to flow out of the ring-shaped channel 6 through the channel g
into the chamber to completely saturate the asbestos wick n and to drop
therefrom into the dish k below. As soon as this takes place the spirit in the
dish is ignited, the chamber h is thereby heated, and the spirit contained therein
is vaporized. As soon as sufficient vapour issues from the openings m of the
chamber hit is ignited by the spirit burning in the dish k, and the size of the
flame can then be regulated by turning the screw f so as to increase or reduce
the supply of spirit to the chamber h.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
A spirit burner consisting of a cylindrical vaporizing chamber having a central
air conduit i provided or not with one or more air openings l, an asbestos-wick or
plate n, an outlet opening for the escape of spirit from the vaporizing chamber to
the dish below, outlet openings or slits m in the upper part of the vaporizing

page_text: chamber, and a dish k below such chamber, combined, arranged and operating
substantially as described.
