COMPLETE SPECIFICATION.
Improvements in Incandescent Gas Lamps.
1, JULIUS MOELLER, of No. 14 Palmo Street, Westminster, in the County of
London, Engineer, 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 :-
When incandescent gas burners such as I have described in my previous
Specification No 10587 of 1894 are employed for lighting streets or other localities
subject to vibration or shaking, the incandescence mantle, which is very fragile, is
apt to give way owing to the vibration conveyed to it through the burner and the
post or other frame which supports it and the pipe which leads to it. The object
of my present invention is to provide against the communication to the mantle of
such shaking or vibration as might cause it to give way, and I effect this by
providing an elastic support for the buruer as Isball describe referring to the
accompanying drawings.
Fig. 1 is an elevation partly in section of a burner similar to that described in
my previous Specification No. 10587 of 1894, with elastic support according to my
present invention
Fig. 2 is a sectional plan on X X of Fig. 1.
Fig 3 is an elevation, partly in section, showing a modification, and
Fig. 4 is a plan on Y Y of the supporting frame for the springs.
Fig. 5 shew's a modification in which a single spring is employed and
Fig. 6 is a part section of an elastic diaphragm support.
Referring st to Figs. 1 and 2 which show the elastic support applied to
existing burners, I fix on the shoulder just above the stop cock an annular plate P
having several stud pins S, of which four are shewn, fixed in and projecting up
from it, each of these being surrounded by a helical spring. On these springs rests
another annular plate Q having holes through which the pins S freely pass On
the plate Q rests the frame F of the gallery which caries the upper part of the
burnel.
The outer tube G of the burner being free to slide on the inner tube H. and also
the top of the cential tube C, which supplies the kindling burner D, being free to
slide in the hole which it enters, the gallery and burner with the mantle supported
on it rest entirely on the springs, and thus any vibration or shaking of the parts
below is deadened before reaching the mantle.
As shown in Figs. 3 and 4, the burue only, and not the gallery, is supported ou
the springs. For this purpose a frame plato P with arms projecting into an
internal groove of the gallery, has holes through which freely pass the stud pins
which are fixed in and project down from the upper plate Q. The helical springs
interposed between P and Q deaden the vibrations which might otherwise be
communicated to the burner and destroy the fragile mantle M.
As shewn in Fig. 5 a single_helical sping is interposed between P and Q, and
in Fig. 6 an elastic diaphragm T, which may be a disc of thin sheet metal circularly
corrugated, carries the burner, a collar K of which rests upon the middle of the
diaphragm whilst the outer edge of the diaphragm rests on an internal ledge of the
gallery.
Obviously, springs of forms other than those shown might be interposed between
the plates P and O.

page_text: Having now particularly described and ascertained the nature of this inven
tion and in what mauner the same is to be performed, I declare that what I
claim 18:-
In combination with an incandescent gas burner, an elastic support, which may
be a spring or springs, interposed between the vertically sliding part of the burner
and the stationary pipe on which it slides, substantially as and for the purpose set
forth.
