Improved Incandescent Spirit Vapour Lamp with Vapour Generator.
We, RICHARD BEESE, of 13, Gluckstrasse, Dresden, Germany, Architect, and
ALBIN PERLICH, of 34, Lauensteinerstrasse, Dresden-Striesen, Germany, Civil
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:-
The present invention has for its object a lamp for producing and burning
spirit vapour.
The spirit is sucked up from a reservoir into a vaporizing chamber by means
of wicks. The walls of this vaporizing chamber are at first heated by means of
an auxiliary flame, which extinguishes after the walls are heated to such an
extent as to set up and maintain constant vaporization. The spirit vapour is
mixed with air within a mixing chamber, beneath which a drum is provided
with air passages, which latter can be opened more or less according to the
amount of air required for a perfect combustion. The mixture of air and spirit
vapour is then ignited at the upper, perforated burner end, which supports the
incandescent mantle or other medium. We prefer to employ self igniting
incandescent mantles. For extinguishing the lamp a valve, ordinarily closing a
passage between the vaporizing chamber and the spirit reservoir, is lifted allowing
the vapour to escape directly into the reservoir.
In order to make our invention more readily understood we have illustrated
it on the accompanying sheet of drawings, Fig. 1 of which shows a vertical
sectional elevation of the entire arrangement, in which the inner air regulating
drum is not shown.
Fig. 2 is a detail sectional view on line 1-1 of Fig. 1,
Fig. 3 shows the air regulating device in elevation,
Fig. 4 is a horizontal section on line 2-2 of Fig. 3 and
Fig. 5 is a top view of the deflecting and heating disc.
The hollow body a is screwed to the upper part of the reservoir containing
the spirit to be vaporized. Into this hollow body a extend a number of tubes 6
containing the wicks e, the lower ends of which dip into the spirit. The upper
ends of the tubes open into the annular vaporizing chamber d and the upper
ends of the wicks lie flush with the bottom surface of this chamber or extend
only very little into the chamber. Within the circular space e, enclosed by
the said chamber d, a tube f is provided, having its lower end closed, and being
provided with a perforated cap fl. This tube f is connected with the vaporizing
chamber by means of a hollow bridge or tube g. The lower end of the said tube f
extends partways into the air regulating device. This latter consists of a drum i
(Fig. 4) snugly fitting into the outer drum h open at the upper end, provided
with a bottom and a number of longitudinal slots k. The inner drum i likewise
is provided with corresponding slots. A pin / fastened to the inner drum i and

page_text: projecting through a slot m in the drum h permits of the drum i being revolved
the length of the said slot m, thereby more or less closing the slots in the two
cylinders.
"
Above the described parts a cylindrical chamber, the mixing chamber n is
provided, the upper end of which carries the burner with the incandescent mantle
or Auer filament." A body o having three passages of, o², o³ is provided at
the junction of the burner p with the mixing chamber n, the stem of which
body is connected with or runs out into the base y for securing the incandescent
mantle holder r. The burner top plate p contains a large number of small
holes s set in a circle and a second circular row of holes of somewhat larger
diameter arranged concentrically with the first row of holes. u is the deflecting
and heating disc, which is provided with holes w, the burner top plate having
corresponding holes v¹.
The working of the lamp takes place in the following manner: To give the
vaporizing chamber d its initial heating the heating ring w is provided, against
which a flame is directed. The spirit to feed this flame is filled into the
receptacle. The heat of the heating disc w soon is transmitted to the walls
of the vaporizing chamber d and causes the spirit sucked up by the wicks_c_to
be vaporized. The vapour takes its way through the tube g, through the holes
in the cap f¹ and into the mixing chamber n, where it is mixed with the air,
which ascends into the mixing chamber », passing around the bridge or tube g.
The mixture of vapour and air now passes through the passages o1, 2, 3 and
through the holes s, tv and and strikes the inner surface of the incandescent
mantle, where it is ignited and heats the mantle to a white glow. The mantle
holder and the disc u soon attain a high heat which is transmitted to the body o,
thence to the wall of the mixing chamber and to the walls of the vaporizing
chamber, which then is kept at a temperature high enough to maintain
constant vaporization. The auxiliary flame a extinguishes after consumption of
the small amount of spirit contained within the receptacle . For extinguishing
the lamp it is only necessary to lead the vapour into the atmosphere or into the
reservoir. This latter arrangement is preferable, as no disagreeable odours can
arise, as is the case in the first arrangement. For this purpose we provide a
tube y the upper end of which opens into the vaporizing chamber and the lower
end of which is angularly bent as is clearly shown in Fig. 1. The front end of
this bent portion is adapted to serve as seat for the plug valve z, provided with
a stem z¹ and a knob 22. Ordinarily this valve is screwed or pushed tight upon
its seat, but when the lamp is to be extinguished, the valve is to be lifted, as is
shown in the drawing and the vapour now takes its course through the tube y
into the hollow body a and in the spirit reservoir.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:-
1/ In an incandescent spirit vapour lamp the combination of a spirit reservoir,
a number of tubes, extending into the upper part of the reservoir and holding
enclosed the suction wicks, the upper ends of which extend into the vaporizing
chamber, a horizontal tube connecting the vaporizing chamber with a vertical
tube provided with a perforated cap, the air admitting receptacle and the mixing
chamber, connecting the said air admitting receptacle with the burner head,
the parts being constructed arranged and working substantially as described.
2/ In an incandescent spirit vapour lamp means for extinguishing the lamp
consisting in the combination of the tube y, connecting the vaporizing chamber
with the reservoir, and the valve z, as set forth.
3/ In an incandescent spirit vapour lamp means for heating the incandescent
mantle holder and adjacent parts consisting in the combination of the burner
head p, the concentrically arranged rows of holes and t, the deflecting and

page_text: heating disc
as described.
the holes v, v and the incandescent mantle holder r",
substantially
4/ In an incandescent spirit vapour lamp means for starting vaporization con-
sisting in the combination of the heating ring w, secured to the outer wall of the
vaporizing chamber and the spirit receptacle r¹ as set forth.
