I, PETER BUCHER, of No. 4, 18. Mannheim, in the Empire of Germany, do
hereby declare the nature of this invention to be as follows:-
This invention relates to an acetylene generator, in which the calcium carbide
located in a perforated, exchangeable receptacle, is-by the aid of a rotatable
lever-forcibly passed from below into a generating vessel open at its base and
filled with water, and in which latter vessel the carbide is decomposed. After
the decomposition has been effected, the carbide receptacle is again moved out of
the generating vessel and the lime residues are removed from the carbide
receptacle.
In the improved apparatus, a generating vessel, closed at its top, is separated
from the water receptacle by a partition wall.
In the said receptacle is arranged a double lever in the extremities of which
the exchangeable perforated carbide receptacle is placed. The fixing of this
receptacle upon the lever may be effected in any suitable manner. In the
present case the receiver is made box-shaped, so that, after the removal of the cover,
it may be easily filled with calcium carbide. By means of a knob or of a handle,
arranged on the said lever, the latter may be placed at will, in either its operative
or inoperative positions. When occupying the inoperative position, the carbide
receptacle lies outside the water, so as to admit of its being inserted in or removed
from the double lever. After the insertion of a newly filled carbide receptacle,
the said lever is so turned, that the carbide receptacle is moved into the genera-
ting vessel.
The acetylene gas generated by the decomposition of the carbide, passes into
the dome, arranged at the upper part of the generating vessel, from which the
gas is conveyed by a tube into the gasometer.
Instead of using one single carbide receptacle, two or more may be employed,
adapted to be actuated in the same manner by levers and to be alternately intro-
duced into the generating vessel, in order to obtain a continuous working of
the apparatus.
The apparatus may be worked by hand or may be so connected with the gaso-
meter, that by the movement of the gasometer-bell or cover the levers, carrying
the carbide receptacles are caused to turn.

page_text: I, PETER BUCHER, of 24 & 25, J Street, Mannheim, in the Empire of Germany,
Manufacturer, formerly of 4, 18, Mannheim, in the Empire of Germany, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
:-
The present invention relates to an improved acetylene gas generator in which
the calcium carbide contained in a perforated exchangeable container, is forced
from below, by means of a turnable lever, into the generating compartment filled
with water, in which the carbide is decomposed.
After decomposition, the carbide container is taken out of the generating
vessel and the residue of lime removed.
I will now describe my invention with reference to the accompanying drawings
in which an apparatus constructed according to this principle is represented, in
a perspective view.
In the drawing the separating wall is constructed as shewn detached from
the bottom of the tank, thus allowing access to the inner compartment, for the
water placed in the outer compartment, and for the carbide holder f.
In the receptacle a, two angular levers, (only one of which is shewn) are
mounted near the two side walls, on the axle, which latter rotates in bearings
formed in the side walls of the receptacle.
The two angular levers have eyes or spiral shaped coils at their extremities
into which is placed the carbide container f provided with central pins at the
two end surfaces. This container consists of a perforated cylinder with a sliding
or other suitable door or cover for admission of carbide. These levers with
coiled ends render an extremely easy, and sure insertion and removal of the
container possible. This mode of fastening the latter is not, of course, essential,
any other suitable mode of fastening being applicable. The levers can also
be of any other shape, for example, arched. The arrangement of the angular
levers has the advantage that the carbide container which, as is well known, is
the principal factor in the generation of acetylene gas, can always be brought
into speedy contact with the water contained in the generating compartment c,
since this peculiar lever arrangement, always and in every case, forces the carbide
container to remain above the layer of residue formed in every generator, a
chance of its failing to act or to generate gas being entirely precluded.
As shewn in the modification represented in the drawings, the container fis
of a cylindrical shape, so that it can easily be filled with calcium carbide when
the cover has been removed. By means of an external handle h, attached to the
axle of the levers or by any other suitable arrangement, the levers, can at
will, be brought into the position marked in full or into that marked in dotted
lines on the drawing. In the position marked in dotted lines, the carbide con-
tainer can be placed outside the water so that it may be inserted into or
removed from the ends of the levers a. After inserting a carbide holder filled
afresh, the levers are turned in such a manner, that the said holder f is brought
from below into the generating compartment c as shewn in dotted lines, the said
container being adapted to be held in that position by means of a counter-
weight attached to the handle h.
The gas generated by the decomposition of the carbide, accumulates in the
upper part of the generating compartment whence the water is displaced in
due proportion, as the gas is generated.

page_text: The generating compartment is provided with a dome d from which the gas
is conducted through the tube g.
Instead of one single carbide holder, two or more may be employed, which are
alternately inserted into the generating compartment, in order to render a
continuous service possible.
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 improved acetylene gas generator characterised by a perforated carbide
container for the reception of calcium carbide, which container is exchangeable
and fastened to the levers in such a manner, that by turning these levers, it
is forced from below to enter the generating compartment e partly filled with
water.
2. In an improved acetylene gas generator as described in the first claim, the
combination of the tank, partition b, dome d, angular levers, having curved
extremities, carbide container f, axle r, handle h, generating compartment c, and
outlet pipe g.
