COMPLETE SPECIFICATION.
An Improved Kerosine Regenerator Lamp.
I, ANTON FAULER, of Stuttgart, 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 -
The object of this invention is to avoid various inconveniences belonging to the
different models of kerosine regenerator lamps in use till now. One of these
inconveniences was, that the oil reservoir in which the kerosine or other liquid
hydro-carbon was to be vaporized, was to be heated by a spirit flame before the
lamp could be lighted properly. Another inconvenience arose from the fatilty
construction of the lamps by which either the evaporation or the combustion of the
gas became insufficient, the latter frequently causing explosions.
The improved lamp is shown in the annexed drawings in which
Fig. 1 is a vertical section through the lamp.
Fig. 2 is an elevation of the regulating cock for the oil inlet.
Fig. 3 is a longitudinal section of the said cock.
Fig. 4 shows the burner in combination with the oil-inlet on a larger scale.
Reference being made to Fig. 1 A is the oil reservoir of annular shape, placed
high above the flame, from which the oil or other liquid hydro-carbon flows through
the tube a through the filter filled with wick, the cock e the union d and the
U-tube to the piece h which is connected with the piece by the socket e.
From the piece the oil passes through the tube 7 to the burner. The tube /
is hollow only so far as the burner (see Fig. 4) and is there provided with a
number of holes, placed equally and radially to the middle of the burner. On this
tube the two burner discs m and n are screwed by their sockets. The upper
and the lower nuts m¹ n¹ are intended to be screwed down upon the discs for fixing
them. On the continuation of the tube the under part is kept solid, the screw
is continued to the end and there carries the under cup-shaped air conductor O. Here
the air is introduced from below through the globe p to the cup, which is always
connected with the glass by the movable ring q.
The oil having arrived in enters the bore of the pipe and quits it by the
small radial holes in the middle of the burner at r to the disc shaped wick which
sucks it up and carries it to the periphery of the wick and here the disc shaped
wick lying between the discs mand n may be lighted easily at its periphery by
a match.
The part t, partly cylindrical, partly conical is fixed to the under plate at the
bottom of the lamp body by sheathing. It serves for conducting air to the burner
from above, this air being sucked in between the outlet pipes u which carry off the
combusted products. The necessary air for the under part of the flame comes from
below through the cup o as above mentioned.
Hot air therefore comes from above and cold air comes from below to the
kerosine gas, issuing from the wick and thus this gas burns between two currents
of air with a fine, white, horizontal annular flame.
By the draught through the waste-pipes u and the chimney the flame at the
end is drawn upward. In consequence of a counter current of air, which circulates
through the small holes w arranged symmetrically round the lamp, a small
current of air is produced to the ends of the flame, which prevents the lamp from
smoking.
The regulating of the flame may be done easily by the cock cc¹ of peculiar
construction.

page_text: The communication of the filter with the opposite continuation of the conduit
is effected by a second cross-bore, vertical to the first, in the middle of the cone
The second bore is closed at the under side and in the wall is cut by a saw a very
fine capillary cleft along the length of the diameter of the under cock-bore. By
turning the cone this cleft may be opened as desired, only partially (Fig. 3)
and the oil flows in quantities as small as desired to the burner. By this means
the oil may be supplied to the flame of the burner in quantities corresponding
exactly with requirement and drops, which are very detrimental to a homogenous
formation of the flame, are not formed. In order to prevent the heating of the
kerosine reservoir, arranged round the funnel, a cylindrical cone is placed between
the reservoir and the funnel, the upper and under holes in which produce a circu-
lation of the air, heated by the funnel, and remove this heated air above. By the
respective holes ¹ in the hood of the lamp a circulation of the air round the
kerosine-reservoir is effected as well, so that the latter never reaches a temperature
sufficient for causing an explosion, as numerous practical experiments have already
proved.
A small hole a¹ in the closing cap of the oil reservoir allows of admission of air
for the easy flowing out of the fluid. By turning the hoody of the funnel the
holes may be diminished and the draught regulated accordingly.
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 :-
1. A regenerator lamp for liquid hydro-carbons, consisting of a reservoir of oil A
in combination with a filter a regulating cock e a tube connected with it ending
in a burner with a wick in the shape of a disc.
2. In the regenerator lamp for liquid hydro-carbons described in Claim 1, the
holes w for the inlet of air, in order to prevent the smoking of the lamp.
3. In the regenerator lamp for liquid hydro-carbons described in Claim 1, a
burner formed of a pin partly hollow and screw threaded to receive the two
discs m and which surround the wick s.
4. In combination with the regenerator lamp described in Claim 1, for liquid
hydro-carbons, the arrangement of filter and of the regulating cock c as herein
described.
