COMPLETE SPECIFICATION.
Invisible Adjusting Apparatus for Electroliers and Gaseliers
and the like.
I, MORITZ WEIDLICH, Architect, of 12, Albertstrasse, Wurzen, 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 invention described hereunder, and illustrated in the accompanying draw-
ing, relates to a contrivance applied to apparatus employed for lighting, such as
gaseliers and the like, in which the lengthening, or shortening of the gaselier,
or other apparatus fixed in a vertical position, that is to say, the keeping it in a
higher, or lower position, is effected with the simplest means the mechanism
provided for this purpose being quite out of sight, by which contrivance it is
further possible to dispense with the chain, and weights, which are certainly
in no way ornamental and to essentially simplify the whole apparatus.
The invention will be understood by the following description, with the assis-
tance of the accompanying drawing, in which
Fig. 1 is a vertical section of the adjusting apparatus applied to a gaselier.
Fig. 2 is a similar view in connection with an electrolier.
Figs. 3 and 4 are cross-sections of Figs. 1 and 2.
Fig. 5 is an external view of a lighting apparatus of the kind in question.
Figs. 6, 7, and 8 illustrate various forms of teeth.
The adjusting apparatus consists substantially of two tubes R and R¹, the one
inserted in the other, the inner fixed tube R being furnished towards the free
end with a pin r (see Figs. 1 and 2).
In the tube R', a suitably strong casing his fixed, the latter being slit from top
to bottom and cut out from the slot line so as to form teeth z and lodgments i.
When the apparatus is adjusted, the pin r of the tube R lies in the incisions
made in the casing and thus keeps the apparatus in the position desired as
regards height.
It is not, however, absolutely necessary that the pin should be placed in the
inner tube and the toothed casing connected with the tube R', the arrangement
can be reversed with equally satisfactory results.
Further, with lighting apparatus, in which it is not necessary to draw the
material to be burned through the rods of the adjusting apparatus, a solid rod
may be employed in place of the tube R.
Whatever the further form of the apparatus may be, the essence of the inven-
tion is that the apparatus is raised, or lowered, and kept at the desired height,
by means of tubes R R adjustable (movable) one within the other and furnished
with recesses or lodgments i and a pin r.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
Adjusting contrivance for gaseliers and similar lighting apparatus to be fixed

page_text: vertically, the distinguishing feature of which is that the raising or lowering of
such apparatus is effected by means of tubes R R¹ adjustable one within the other,
and retained in the desired position by means of catches or lodgments i and
a pin r.
