Improvements in Devices for Raising the Burner-gallery in
Lamps.
We, FRITZ BAUDISCH and ERICH HEINE, both of 149, Koepnickerstrasse,
Berlin, S.O., Lamp Manufacturers, do hereby declare the nature of this inven-
tion 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 a simple and convenient device for raising the
burner galleries with appurtenances in lamps for lighting the same or other
purposes.
Referring to the accompanying drawing,
Fig. 1 is a vertical section of the respective portion of a lamp showing the burner
gallery as lowered.
Fig. 2 the same with the burner gallery raised.
Fig. 3 a horizontal section along line y Fig. 1.
In the lower portion of the burner is revolubly lodged a key a with its bit b.
The latter part carries at its free end a pin ce catching into a slit d of the
horizontal cross bar e. Said cross bar is bent with its ends bow-fashion around
the inner wick tube and carries at its extremities the vertical rods diametrically
provided opposite each other and guided in two tubes g secured in the burner
basket. These rods carry at the top a ring surrounding the outer wick tube.
A second ring i is detacheably connected, by a kind of bayonet closing through
overlapping hooks k, with ring h. Ring i carries at the top by aid of stays
the burner basket or gallery m. The slot d mentioned above is situated, corre-
sponding to the turning direction of key a, in the right half of cross bar e and
extends but for a short distance into the left half. The length of the key bit i
corresponds to half the height to which the burner gallery can be raised.
To give the latter its highest position, thereby laying the wick free for the sake
of commodious lighting of the lamp, merely the key a is turned for about 180 degrees
to the right.
Thereby the pin e describes a semi-circle and runs while lifting the relatively
connected parts efhiklm through slot d, first from left to right and after
exceeding the right angle that is to say the horizontal position of the key bit b,
from right to left as far as the end of the slot. The bit now assumes the
slightly inclined position shown in Fig. 2. and prevents, as the pin c cannot
advance further in slot d to the left, the raised parts from spontaneously
descending by their own weight. The sinking of the gallery can take place
only by turning back the key a into its former position.
In contradistinction to the known raising devices of this class with pin and slot
guiding, the improved device has the advantage, that the lifting of the gallery is
effected, not as in those, by the depressing of a hand lever, but by turning of a key
similar to the ordinary wick key. Such a key is more easily and securely handled
than a lever arm, which, according to experience, is always handled with a certain
amount of uncertainty and anxiety. By this reason the turning key is employed
almost exclusively in new constructions.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
A device for raising the burner gallery of lamps, in which the raising and fixing
of the gallery is so effected by means of a turning key a as to cause the pin c
connected to the lower end of the key bit to be turned for a little more than

page_text: 180 degrees upward, thereby taking along a vertically displaceable cross bar e
which carries the burner gallery m, said pin moving, during this process, to and fro
in an unilateral slot d of the cross bar, substantially as illustrated and described.
