Improvements in Incandescent Gas Light Burners.
I, ADOLF ROSENTILAL, of l'eterstrasse 22, Cologne, Germany, Merchant, do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in incandescent gas light burners and
has for its object to overcome the danger to the mantle arising when the chimney
is taken off which frequently leads to the destruction of the mantle, on account
of the chimney adhering so firmly to the gallery that a certain effort is required
to remove it therefrom.
To avoid this I construct the burner so that the chimney can be removed together
with the gallery, while the mantle is left on the burner. To facilitate this I
put on the burner tube a disc with a centre rim on which the burner gallery is
lodged centrically.
I may also use advantageously, as a connection between the burner gallery and
the burner glass, a vase or cup which replaces the connecting metallic parts as
used in other known systems. This glass vase or cup is either arranged so that
a rim projecting towards the outside carries the burner gallery or that a rim
projecting towards the inside serves the same purpose. According to whether
one or the other plan is adopted the glass vase will have a lesser or greater
diameter.
In order to increase the possibilities of application of the burner, with the
abovementioned construction, I arrange within the burner a socket into which
the mantle-support is fixed and which can be unscrewed out of the burner together
with this support. Convenient removal and exchange of the mantle-support (of
iron or magnesia) is rendered possible, while in other constructions it may be
necessary to drill it out, in a rather laborious manner.

I, ADOLF ROSENTHAL, of 88, Ritterstrasse, Berlin, S., in the Empire of Ger-
many, formerly of Peterstrasse 22, Cologne, Germany, Merchant, do hereby

page_text: formed, to be particularly described and ascertained in and by the following
statement:—
The removing of the glass cylinder of lamps for incandescent gas light is often
connected with the risk of damaging the mantle as the glass cylinder is in
many cases held fast by the pinching arrangement of the so-called gallery in
such a manner that the application of force and the striking of the cylinder
against the mantle or its holder cannot be avoided.
This improvement serves for the prevention of such unintended and destructive
knocks. For this purpose the gallery so formed that in removing the glass
cylinder from its place it will remain in connection with the latter while the
mantle is secured in its normal position by means of a holder arranged con-
centrically to the longitudinal axis of the burner and being thereby completely
isolated and out of contact with the glass cylinder.
In the annexed drawing Figs. 12 and 3 represent different forms of con-
struction of the invention partly in longitudinal sections through the burner while
Fig. 4 shows the fastening of the mantle holder on the burner tube.
In all cases an annular base b provided with a horizontal flange is secured on
the burner tube a. This base supports the gallery consisting of a cylinder
receiving shell d notched to make it elastic a horizontal ring disc e and a notched
vertical rim f. According to the position of the flange c on the interior or
exterior side of the projecting vertical rim of the shell da contact with the
jagged rim of the gallery or with the interior side of the lower rim of the glass
cylinder will be effected leaving sufficient intermediate space. Both forms are
illustrated by Fig. 1 and 2. In both cases the base is formed of glass while if
applied to the form of execution represented in Fig. 3 it consists of metal having
the form of a flat disc provided with a conical inner cylinder this disc being
supported by a plate supplied with holding teeth m and being rigidly con-
nected with the burner tube a.
The mantle support or rod k arranged axially to the burner tube is held by
a shell placed within the burner tube and preferably secured by a screw.
The lower end of the shell is supplied with a small axial boring for the intro-
duction of a thin pressure pin to ease the rod k should it require to be pushed
out for replacing.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In incandescent gas light lamps a removable gallery for holding the glass
cylinder formed of two concentric rings d f arranged at a certain distance apart
and connected at their lower edges by a horizontal perforated disc e projecting
to the inside, the interior ring a being notched to clamp the glass cylinder lean-
ing against the inner wall and resting upon the inner rim of the horizontal con-
necting disc e while the exterior ring f serves for the lifting of the glass cylinder
together with the gallery from the horizontal ring c of a base attached to the
burner-tube of the lamp and embracing the latter concentrically all substantially
as described.
2. In incandescent gas light lamps removable gallery for the holding of the
glass cylinder formed of two concentric rings d f arranged at a certain distance
and connected at their lower edges by a horizontal perforated disc e projecting
to the inside, the inner ring d being made elastic by means of notches at the
upper edge, the side surface serving to clamp the glass cylinder, which leans against
the inner wall and rests on the inner rim of the horizontal connecting disc e
while the exterior ring f serves for the lifting of the glass cylinder together with
the gallery from a concentric disc n connected with the burner tube of the
lamp and provided at the rim with several notches m bent upward forming
securing teeth which engage with small notches in the gallery disc e insuring
relatively the concentric position of all parts all substantially as described.

page_text: 3. In incandescent gas light lamps the embedding of the mantle holder k.
axially to the glass cylinder in a shell i placed in the centre axis of the burner
and provided at the lower end with a perforation all substantially as described.
