Improved Apparatus for Producing and Utilizing Acety
Cab.
I, GUSTAVE TROUVÉ of 14, Rue Vivienne, Paris, France, Electrician, 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 relates to improvements in the apparatus for lighting by means of
acetylene gas forming the subject of a previous Application for Letters Patent
dated December 7th 1895 No. 23521.
The present improvements consist :-
1st. In a novel arrangement of condenser for collecting the aqueous vapours
carried along with the gas and for cooling the gas to a certain extent;
2nd. In the application to the generator of a siphon for preventing the escape
into the atmosphere of the gas generated in excess.
In order that the invention may be readily understood I have illustrated the
improvements in the apparatus, by way of example, in the accompanying drawing
which represents a vertical section of the improved combined generator and lamp.
The generator c which may be of glass or metal is closed by a metal cover c¹
(instead of by an india-rubber stopper) supporting a condenser n filled with very
small beads n', preferably of glass, or with any porous material or substance
capable of absorbing moisture, the beads or porous material being retained
between perforated metal plates n. The condenser n is traversed by a siphon
formed by a tuber passing up the inner side of generator c and terminating at its
upper end at a point near the burner and having its lower end at a suitable height
above the removable bottom d of the generator. This removable bottom dis
connected to the body portion e by means of a bayonet joint or other suitable
connection. Upon the bottom d a wire cage e is supported at a suitable height
therefrom by a frame of cross wires s, instead of being suspended as formerly,
frames being either attached or not to the cage. In this manner accidental
falling of the cage and precipitation of the carbide crystals into the liquid is
avoided. A too sudden and excessive production of gas is thus prevented. The
tuber is united and communicates by an aperture t with a tube u whose lower end
opens near the bottom d of the container c so as to form a siphon. In this manner
when the pressure of gas in the generator c depresses the level of the liquid until
it reaches the open lower end of tube r, the gas produced in excess will pass up
said tube to the burner instead of escaping into the atmosphere and imparting
thereto its penetrating odour. Immediately the gaseous pressure is reduced, the

page_text: liquid rises in the generator c and seals the tubes rt. Instead of two tubes as
described, a single tube may be used but of larger sectional area so that the gas
may rise therein simultaneously with the descent of the column of water.
When the apparatus is used not as a lamp but as a generator, the tuber instead
of leading to a point above the burner, which would be omitted, would connect
with the gas outlet pipe above the cock w.
Such are substantially the improvements which I have made in my apparatus
of which the forms, dimensions, details, accessories, and materials, may vary
according to the nature of the application.
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 :-
In a combined generator and lamp for producing and utilizing acetylene gas
for lighting purposes, the combination of the receiver supporting a condenser
filled with beads or porous material in a divided condition and a safety siphon
with a cage for containing the carbide supported by a frame at the proper height
within the receiver into which it is introduced from the bottom all substantially as
hereinbefore described and for the purpose specified.
Dated this 23rd day of October 1896.
