Complete Specification Left, 16th Oct., 1896-Accepted, 12th Dec., 1896
I, JULIUS MOELLER, of No. 14 Palmer Street, Westminster, in the County of
London, Manager, do hereby declare the nature of this invention to be as
follows:-
In my Specification No. 9070 of 1895 I described various ways of mounting
incandescent gas burners on springs so as to provide against shaking or vibration
such as might cause the very fragile mantle to give way.
According to my present invention, instead of supporting the burner on springs
placed beneath it, I suspend it by springs in such a way as to give it freedom for
lateral as well as vertical play. When the burner is in a lantern as for instance
for street lighting, a cross or disc on which the burner is carried is suspended by
light extensible springs from the upper part of the lantern frame, and when there
is a chimney of more or less height or weight above the burner, I prefer to steady
it by connecting its upper part by light extensible springs to the suspending springs
or their points of attachment. In like manner the arms of a chandelier which
carry the burners are suspended by light extensible springs from the gas pipe
which projects down from the ceiling. According to a modified arrangement, the
gas pipe descending from the ceiling is divided into two parts both closed at
their ends and connected by a blade spring of zig-zag form, the gas flowing
from the upper to the lower section of the pipe through a flexible by-pass
pipe.
'Whenever springs are used as above described it is necessary to connect the
burner pipe which is carried by the springs to the fixed pipe by a connection
which will admit of their relative play, such as a piece of flexible tubing.
I prefer, however, to employ whenever the fittingswill admit of it, a connection
of the following kind.
The one section of pipe terminates with a bell, the other terminates in a cup
which is larger than the bell and is charged with suitable liquid such as oil or
glycerine.
The bell of the one section being partly immersed in the liquid contained in
the cup of the other section, there is a sealed junction admitting of relative
play of the two sections both horizontally and vertically.

COMPLETE SPECIFICATION.
Improvements in Incandescent Gas Lamps.
I JULIUS MOELLER of No. 14, Palmer Street Westminster in the County of
London, Manager 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 my Specification No. 9070 of 1895 I described various ways of mounting

page_text: incandescent gas burners on springs so as to provide against shaking or vibration
such as might cause the very fragile mantles to give way.
According to my present invention instead of supporting the burner on springs
placed beneath it, I suspend it by springs in such a way as to give it freedom for
lateral as well as vertical play.
The accompanying drawings shew the application of my present invention to
street lamps and suspended chandeliers.
Figure 1 shews in elevation, partly sectional the mounting of an incandescent
burner in a street lantern which may be subject to shocks and vibration resulting
from traffic.
Figure 2. shows in elevation also partly sectional the mounting of a chandelier
carrying two or more incandescent gas burners and suspended from a ceiling subject
to shock or vibration from movements on the floor above. As shewn in Figure 1,
a cross piece or disc A on which the burner B is carried is suspended by bent
wires C attached to the bottom of a tube D which is suspended by a light
extensible spring E from a cross piece or wires F fixed in the upper part of the
lantern frame L.
The tube D enclosing the spring E serves to protect it against over heating or
injury by the hot products of combustion passing upwards, and therefore, it is
preferably made of glass, ceramic or other material which is a bad conductor of heat.
When there is a chimney G such as is shewn exceeding in height or weight an
ordinary glass, I prefer to steady it by connecting its upper part by light extensible
springs H to the suspending wires C. I suspend, as shewn in Figure 2, the arms K
of a chandelier by light extensible springs E' from the gas pipe M which projects
down from the ceiling.
When springs are used as above described, it is necessary to connect the pipe of
the burner B which is carried by the spring or springs to the fixed pipe M by a
connection which will admit of their relative play.
For this purpose the one section of the pipe is made to terminate with a b N
the other section with a cup P which is larger than the bell and is charged with
suitable liquid such as oil or glycerline, or water with oil floating on it. The
bell N being partly immersed in the liquid contained in the cup P there is thus
constituted a junction sealed by liquid against escape of gas, but admitting of
relative play of the two sections of pipe both horizontally and vertically.
Instead of connecting the burner pipe to the gas supply pipe by the liquid seal
joint above described, the connection inay be made as shewn in Figures 3 and 4.
In this construction both sections of the pipe are made to terminate in discs N
and P which are connected together by flexible leather or other suitable gas tight
material Q applied in the same manner as in forming the hellows of a dry gas
meter.
The two sections of pipe are thus connected by a gas tight junction admitting of
their relative play both horizontally and vertically.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed I declare that what 1
claim is
i. In incandescent gas lamps exposed to shaking or vibration, dividing the gas
pipe into two parts connected by a bell in a cup containing liquid and suspending
the burners by light extensible springs, substantially as described.
2. In substitution for the hell and cup for connecting the two parts of the gas
pipe a joint formed by leather or other flexible gas tight fabric attached to discs
fixed on the ends of the pipes substantially as described.
