Improvements in or Applicable to Lamps.
I, SALOMON FALK, of the firm of Falk, Stadelmann & Company Limited, of
43, Farringdon Road, in the County of London, Manufacturer, do hereby declare
the nature of this invention (a communication from abroad by Messrs. Schwintzer
and Gräff of 13 Sebastian Strasse, Berlin, in the Empire of Germany, Lamp Manu-
facturers,) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention relates to improved mechanism for raising and lowering the galleries
carrying the chimneys of lamps and to improved guides for such galleries.
In carrying out my invention I provide the usual lifting key with a lever the free
end of which is adapted to engage with a cross bar connected to uprights upon which
the gallery is mounted and I arrange the said uprights to slide in guides rigidly
secured to the air screen or sieve.
To enable the said invention to be fully understood I will describe the same with
reference to the accompanying drawing in which, for the purpose of illustration, I
have shewn the invention applied to what is known as a central draught lamp.
Figure 1 is an elevation, partly in vertical section, through the burner and gallery
of the lamp, the parts being in their normal position.
Figure 2 is a view similar to Figure 1 showing the gallery raised, and
Figure 3 is a horizontal section on the line x, x, Figure 2.
a is the wick tube, 6 the perforated air screen or sieve, c the dome, d the chimney
gallery and e the lifting key, all of which parts are of the usual construction.
f is the lever which is secured to the inner end of the lifting key e, the free end of
the said lever engaging by means of a pin g in a slot h in the cross-bar i.
k, kare the uprights to which the cross-bar i is connected and upon the upper ends
of which the gallery is mounted.
With this arrangement it will be obvious that, assuming the parts to be in the
position shown in Figure 1, if the key be turned in the direction of the arrow, the
leverf moving with the key will raise the gallery into the position shewn in Figure 2,
the pin g sliding in the slot. The key when turned in the opposite direction will
lower the gallery.
The uprights carrying the gallery are advantageously of T-shape in cross section
as shown in the drawing and slide in vertical guides 1, 7 attached at their lower ends
to the screen or sieve and projecting upwards through the cone c as shown in
Figure 1 so as to project between the dome and the chimney when the latter is
applied.
It will thus be seen that no part of the guides projects below the bottom of the
burner.
By springing the lever so as to move the ping out of the sloth the gallery and
dome can be removed thereby enabling the sieve to be readily cleaned.
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 lamp burner, the chimney carrying gallery of which is adapted to be raised
and lowered by means of a lever having a pin working in a slot in a cross bar secured
to uprights upon which the gallery is mounted, substantially as described.
(2.) A lamp burner having a lifting gallery the guides of which are arranged to
project through the dome substantially as and for the purpose described.

adapted to be raised and lowered by mechanism substantially as hereinbefore described
and illustrated in the accompanying drawing..
