An Improved Raising and Fixing Arrangement for the Burner
Galleries of Lamps.
I OTTO WOLLENBERG, Metal Goods Manufacturer, of 11 Luckauerstrasse,
invention
Berlin in the Empire of Germany, do hereby declare the nature of this
to be as follows:-
In an apparatus constructed iaccording to this invention there are fastened to the
burner body and at both sides of the burner, guides in which slide, up and down
toothed rods to the top of which the gallery is secured the motion being kept
vertical by pins and slots. Toothed sector wheels mounted on a common spindle
engage in the said toothed rods to operate the gallery..
In order to maintain the gallery in its raised position until it is desired to lower
it a fixing arrangement is provided comprising a catch or stop spring which as the
gallery is raised is forced outwards by a cam on one of the toothed sectors and
allows a projecting pin on the corresponding sliding toothed rod to pass, it after
which the further turning of the sector disengages the cam which permits the said
spring to place itself underneath the said projecting pin and prevent it from falling
until the turning of the sector again causes the cam to displace the supporting
spring to allow the aforesaid pin to pass and the gallery to be lowered.

COMPLETE SPECIFICATION.
An Improved Raising and Fixing Arrangement for the Burner
Galleries of Lamps.
1, OTTO WOLLENBERG, Metal Goods Manufacturer, of 11 Luckauerstrasse,
Berlin 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 :-
In an apparatus constructed according to this invention there are fastened to the
burner body, and at both sides of the burner, guides in which slide up and down
toothed rods to the top of which the gallery is secured, the motion being kept
vertical by pins and slots. Toothed sector wheels mounted on a common spindle
engago in the said toothed rods to operate the gallery.
In the accompanying sheet of illustrative drawings
Fig. 1 is a vertical section of a lamp fitted with this invention in its normal
position.
.
Fig. 2 is a vertical section showing the burner gallery in its raised position.
Fig. 3 is a horizontal section through the toothed rods d in Fig. 2 and
Fig. 4 is a detail view.
Guide sleeves.cfixed at both sides of the burner to the burner body, are provided,
in which slide up and down toothed rods d to the top of which the gallery is

page_text: secured, the motion being kept vertical by pins working in slots in the guides c.
Toothed' sector wheels rotated' by a finger spindle engage in the toothed' rods d
to operate the gallery.
In order to fix the gallery in the highest position (Fig. 2) the bent band spring k
is fastened to the top end of the guide sleeve c. The free end of this spring rests
continuously on the inner side of the sleeve c. On the inside of the toothed
sector ha wedge shaped ridge is formed having its lowermost end projecting
more and being rounded off!
When in raising the gallery the key and therefore the toothed sectors h are
rotated, the wedge-shaped ridges / engage with the band springs k and press them
sideways away from the sleeve sufficiently to allow the guide pins on the
toothed rode d to pass freely. When raised to the highest position the toothed
sectors come above the springs k so that the latter fall back again' on to c. The
pins now rest, as shown in Fig. 2; on the upper edge of the springs & thus looking
the parts in their raised positions.
To lower the gallery the key is-rotated so that the wedge-shaped ridges 1-again
release the springs & and allow the pins to pass. The play of the spring can
be limited by a catch m. The moving and locking mechanisms can be also provided
separately instead of conjointly, as in the arrangement described.
F
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A locking arrangement for such lifting arrangements of the burner galleries
for lamp, as are actuated by toothed rods and tooth sectors; characterised by, the
toothed sector being provided with.a' releasing wedge for the locking, spring &
of the gallery, substantially as described. ·
2. Raising and fixing arrangements for the burner galleries of lamps, constructed
and operating substantially as described with reference to the drawings.
