Improvements in Acetylene Gas Lamps.
I, SEPTIMUS RICHTER, of 25, Bärenschanzstrasse, Nuremberg, in the Empire of
(ermany, do hereby declare the nature of this invention and in what manner tho
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention relates to improvements in acetylene gas lamps particularly such
as are employed for pneumatic cycles and vehicles, the object being to construct
a lamp the carbide vessel of which is furnished by the cylinder of the tyre inflator,
and the lamp is constructed so that it can easily be fixed to a cycle or it can
be used as a hand lamp and taken to pieces. The cylinder of the pump which
contained the carbide can readily be converted to its original office for inflating
tyres.
Such being the nature and object of my said invention the following is a com-
plete description of same, reference being had to the accompanying drawings, in
which:-
Fig. 1 is a tyro inflator having the upper part of its cylinder broken away.
Fig. 2 is a section of the body of the lamp.
Fig. 3 represents the water supply ball or cistern.
Fig. 4 is a cross section through the cap which connects the pump cylinder when
employed for a carbide vessel to the lamp body.
Fig. 5 shews the lamp arranged as a hand lamp.
Fig. 6 is a view of the lamp arranged as a cycle or vehicle lamp in its position
on a cycle.
According to this invention the lamp consists of an inflator 1 (see Fig. 1) with
the piston removed therefrom, a lamp body 3 and a water supply ball or
cistern 4. The pump cylinder 1 is closed by a cap 6 when used for a carbide
vessel and has a projecting pipe 5 near the top. The upper part of the cap G
consists of two hollow cylindera arranged one inside the other, and through which
is the passage way or channel 7 (see Fig. 4). The gas box or guide 8 is con-
structed in a similar manner. The elastic ball acting as a water supply
chamber or cistern has a valve cock 9 for regulating the flow of water into the
carbide vessel.
When the inflator is converted into a carbide vessel the piston 2 is removed
and the pump cylinder is filled or charged with pieces of carbide, and the cap 6
is screwed down onto the top of the cylinder 1. The ball 4 for containing the
water is screwed to the projecting pipe 5 and the pipe 11 in the cap 6 is con-
nected to a pipe 12 of the drying chamber 8 by india rubber tubing 13. The
lump is now ready for use.
When the cock 9 is opened the water flows from the ball 4 through the pipe 5
into the cylinder 1 which constitutes the carbide vessel. The generated gas
passes through the openings 14, 15 and the channel 7 in the cap 6 and escapes
through the pipes 11 and 13 to the drying chamber 8, passes through the channel 17
therein and escapes through the burner and is ignited in the lamp body 3. By

page_text: passing through the various openings in the cap 6 and drying chambers 8 the gas
is dried and a quiet and steady flame results.
When it is desired to construct the lamp as a hand lamp (see Fig. 5) the drying
chamber 8 is screwed into the nut 18 on the cap 6 and the lamp body 3 is directly
fixed upon the carbide vessel 1.
If on the other hand a bicycle lamp is desired (see Fig. 6) the cylinder 1 is
fastened to the cycle frame by bands or clamps and the lump body 3 is fixed on
the ordinary lamp bracket fixed to the steering head of the bicycle.
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) In an acetylene gas lamp the combination of a pump cylinder 1 filled with
carbide, with a lamp body 3, an elastic ball 4 serving as a water supply chamber
and means for connecting the aforesaid cylinder to the lamp body and the water
ball.
(2) In an acetylene gas lamp the combination of a cylindrical carbide vessel
with a lamp body, an elastic water supply ball, a cap 6 fixed on the top of the
said cylinder and having a gas passage way 7 in its upper part and connected
by a nine 13 to a drying chamber 8 fixed to the said lamp body and enclosing a
channel 17 to guide the gas to the burner.
(3) In an acetylene gas lamp the combination of a cylindrical carbide vessel
with a lamp body, an elastic water supply ball, a cap 6 connected as foresaid to
a box 8 on the lamp body and a pipe 5 extending from the cylinder 1 and bearing
the water supply ball 4, a cock 9 being arranged between the said pipe and ball.
(4) In an acetylene gas lamp the combination of an inflator cylinder having a
projecting pipe 5 for connection with the water supply ball 4 through cock or
valve 9.
