COMPLETE SPECIFICATION.
Improved Acetylene Gas Burner.
I, GUSTAVE GEISSELER, of Neuveville, Canton of Bern, Switzerland, 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:-
This invention for an improved acetylene gas burner has for its object to
provide a burner which shall effectually withstand the heat of the flame and
shall not become clogged or rapidly worn out with the passage of gas and heat
of the flame.
In the accompanying drawings Fig. 1 is a plan and Fig. 2 is a vertical sec-
tion through the-line - Fig. 1 of an acetylene gas burner constructed accord-
ing to this invention.
:
The burner proper B is made out of very hard material, preferably of precious
stone, bored through at A, set into a metal stopper M which is screw threaded
at 1 and thus adapted to be screwed into the end of the gas pipe on which the
burner is generally placed. On a rim C of the stopper M is placed a cap E
of metal or other suitable material, provided with a hole F corresponding to
the orifice A of the burner, but a little larger than that orifice. A certain
space is left between the bottom G of the cap and the upper part of the burner,
and the cap may be provided with a certain number of openings such as a, b, c,
allowing the outside air to get into that space to be drawn with the gas going
out at A. The gas flame is therefore produced at the outside part of the hole F
and it is the part of the cap where that hole is which is usually burnt by the
heat of the flame, so that it will be sufficient to replace the cap now and then
involving only a small expense, the burner itself lasting almost indefinitely.
The use of precious stone such as for example sapphire, ruby, garnet, etc., for
the fabrication of the burner, makes it last very long, and a needle or a wire
may be run through the hole to clean it without running the risk of enlarging
or spoiling it.
:
The burner which is the object of this application may have very different
forms and dimensions. The manner of fixing the stone may also differ; for
example, the bored precious stone may be set as they are in watchmaking or
simply held between two metal pieces screwed one into the other, or the one
on the other, etc.; the forms or dimensions of the cap, as well as the material
used for its making, may differ.
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:
1.. An acetylene gas burner composed of the burner proper of hard material,
bored through, on which is placed a removable cap bored with a hole corre-
sponding to the orifice of the burner, and provided with openings to let the

page_text: outside air enter, being meant for protection of the burner against the action
of the gas flame.
:
2. In the burner above claimed: the burner proper made of precious stone
and bored through substantially as described.
