page_text: A communication to me from Dr. LEON STEINER, Civil Engineer, of Rue Academiec,
2, Bucarest, Roumania.
I, EDMUND EDWARDS, of the Firm of Edwards and Co., Chartered Patent Agents
and Engineers, of 65 and 66, Chancery Lane, in the County of Middlesex, 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, and
accompanying drawing, that is to say :-
This invention relates to improvements in acetylene generators, and it has for its
object to provide a generator so constructed and arranged that it occupies as little
space as possible. This is of special importance in cases where the apparatus is
designed to supply the gas directly to a lamp, such as a street lamp, or the like.
The present invention consists essentially in an acetylene gas apparatus, which can
be entirely placed in the lower part of an ordinary street lamp.
The invention is illustrated in the accompanying drawings, in which
Figure 1 is a vertical section through the lower hollow part of a lamp;
Figure 2 a horizontal section on the line x-x of Figure 1;
Figure 3 a side view of the upper part of the apparatus ;
Figure 4 a side view; and
Figure 5 a plan view of the carbide vessel.
In the interior of the gasometer is attached to the gasometer shell a a carbide
holder b in such a manner that it is immersed into the water of the gasometer when
the shell descends. Thus the generation of gas is regulated according to the rate of
its consumption, as the tank is immersed more or less according to the pressure of
the gas.
When the pressure reaches a sufficient degree, the tank is entirely drawn
out of the water and the formation of acetylene ceases.
The carbide tank b consists of several separated partitions 61, 62, 63. . ., (Figures
4 and 5), provided with perforated or sieve bottoms, which are arranged at different
levels, so that the carbide is attacked gradually by the water for the purpose of pre-
venting any excessive formation of gas.
The shell a is provided with a detachable cover e to which is attached the carbide
tank b. The cover is fixed to the shell by means of a pivotted bow d, d¹, whose
hook dengages with a pin on the shell, thereby pressing the cover down to the shell.
The tightening may be made in any suitable manner, for instance by means of an
india-rubber ring.
The highest position of the shell is limited by a stop.

If used for street lamps, the apparatus is so constructed that it can be placed
entirely in the lower hollow part of the lamp, the latter being accessible by a door f.
In this case the shell a is connected to the gas-pipe of the lamp by means of a
flexible intermediate piece such as a hose pipe, or its equivalent.

page_text: 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. An acetylene apparatus, characterized by a carbide tank b attached to the
shell a in the interior of the gasometer, in such a manner that it dips into the
water of the gasometer, when the shell descends, substantially as described, and
for the purposes set forth.
2. In apparatus of the kind mentioned in Claim 1, a carbide tank b composed of
several separate partitions, 61, 62, 63, the perforated or sieve bottoms of which are
arranged at different levels, so that the carbide may be attacked successively by the
water, substantially as described.
3. In apparatus of the kind mentioned in Claim 1, a shell a provided with a
detachable cover e, to which is attached the carbide tank b, the cover being fixed to
the shell by means of a pivotted bow, d, d¹, substantially as described and for the
purposes set forth.
4. In apparatus of the kind mentioned in Claims 1 and 2, the combination of
the gasometer c with a rising pipe h which serves as a safety valve, substantially as
described.
5. The combination of an apparatus of the kind mentioned in Claims 1, 2,
and 3, with a street lamp, the apparatus being placed in the lower hollow part g
of the lamp, the latter being accessible by a door f, substantially as described and
for the purposes set forth.
