Improvements in Devices for Lighting Gas Lamps and the like.
I GUSTAV HECKERT, Doctor, of Lindwurmstrasse 6, Munich in the Empire
of Germany, 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 provide means for permitting the lighting of
gas jets in the interior of lanterns and the like from outside said lanterns without
any door or the like in the latter requiring to be opened.
The new device for this purpose is represented in the annexed drawings in Fig. 1
in longitudinal section and in Fig. 2 in side elevation together with the lighter. It
consists of a pipe bent in U form which starting inside the lantern at D beginning
from the burner tube B, bends downwardly, comes forth out of the lantern through
the sleeve J and then turns up again so as to re-enter the lantern and end on a level
with and alongside in close proximity to the burner. The upward free arm of the
Ushaped tube E is provided with holes or slits S lying at suitable distances apart
above one another. If now the gas pipe leading to this tube, and simultaneously
that leading to the burner, is opened and if, by means of the lighter the gas coming
forth through the lower slits of the tube E lying outside the lantern is inflamed, a
so called running flame will be lit, that is to say, each flame kindles automatically
the gas jet which comes forth through the slit or orifice next above, and the upper-
most flame then lights the gas issuing from the burner, whereupon the supply of
gas to the tube E may be cut off.
This lighting or fuse tube may also be arranged in such a manner as to branch
off from the burner tube outside the lantern, before entering the latter through a
suitable lateral orifice and ending near the burner.
In the annexed drawing a construction is illustrated which renders it possible to
regulate the gas feed by the aid of one gas cock only in such a manner that the gas
is allowed to pass either to the main burner only or to the main burner and fuse
burner simultaneously. For this purpose two passages F and G are arranged
within the body of the gas cock A of which either only one or both can, by having
a correspondingly spacious bore to the plug of the cock, be placed in communication
with the gas supply pipe. The one of these passages G is, by means of a pipe C,
within the pipe B, in connection with the main gas burner, whilst the other
passage F communicates by means of the outer pipe B with the fuse burner. If
now the main gas burner is to be lit, the plug of the cock is turned so that the gas
supply communicates with the main burner as well as with the fuse burner.
Application of the lighter to the fuse burner will cause a running flame on the fuse
burner whereby the lighting of the main flame is effected. After this is done the
plug is turned so that only the passage G remains in communication with the gas
supply pipe, whilst the passage F to the fuse burner is closed (position of the cock
shown in dotted lines in Fig. 1) consequently only the main burner continues
burning. For extinguishing the lamp, the plug is turned so that both passages F
and G are closed.
The lighter K by which such lamps are preferably lit is shown in Fig. 2 and
consists of a lamp such as ordinary lighters have, surrounded by a casing K' in the
end of which is an orifice K2 with a funnel L which will allow of its being easily
guided and placed on the fuse tube E when the lamp is to be lit and which also,

page_text: during this manipulation, places itself closely against the lower edge of the
socket J so that even in wind the lighting will be effected without difficulty.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
:—
1. A device for applying light to gas jets without direct access to said jets
comprising a fuse tube E placed in communication with a gas supply pipe and
extending from an accessible place for lighting to the burner to be lit, this fuse
tube being provided with suitable slits or holes S adjacent to one another for issue
of gas to produce a running flame along the fuse tube when a light is applied to its
accessible end substantially as set forth.
2. The construction of fuse-tube in U form, substantially as set forth.
3. The combination with the fuse tube described in Claim 1, of a gas cock
having two passages F and G arranged in its body, one of said passages com-
municating with the main burner and the other with the fuse tube so that by
turning the plug of the gas cock, both passages, or only that leading to the main
burner, are set in communication with the gas supply pipe.
4. The lighter K having at its top an orifice and a funnel L adapted to admit
the fuse tube E projecting out of a lantern through a sleeve J and to be placed
closely against the lower edge of the said sleeve J substantially as described.
