COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus for the Production of
Acetylene Gas.
I, MAX FOURNIER, Engineer, of 3, Dresdenerstrasse, Dresden, in the Empire of
Germany, 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 improvements in or relating to apparatus for the production of
acetylene gas has for its object to provide an acetylene gas apparatus with automa-
tically regulated supply of calcium carbide, the characteristic feature of which is that,
in case of diminution of the quantity of gas in the gasometer, the gasometer effects
an automatic supply of calcium carbide by means of a sliding apparatus, actuated by
tension or pressure.
The supply of calcium carbide is regulated by placing the material above the
generator in separate boxes, bags or the like, in a special case by means of the different
covering sides of which it is held over a slanting inlet shaft.
The sliding apparatus being actuated by the gasometer, gradually releases the
covering sides; the respective covers fall under, and the particular carbide. holders
drop through the inlet shaft into the generator.
In the accompanying drawing by way of example an acetylene gas apparatus
with such automatically regulated supply of the calcium carbide, is illustrated.
Fig. 1 is a longitudinal sectional elevation of gas generating apparatus constructed
according to this invention.
Fig. 2 is an end elevation with the feeding arrangement in cross section.
Fig. 3 is a plan of Fig. 1 and
Fig. 4 illustrates a modified form of apparatus for actuating the feeding arrange-
ment.
a indicates the gasometer, b a guide roller by means of which the gasometer bell a
is guided in the known manner on the rail c. d represents the generator which is
connected with the gasometer by means of a gas pipe e. Above the inlet shaft f which
is widened at the top in the form of a funnel, is arranged a case or box y consisting
of separate compartments in which the boxes, bags or the like h containing the
calcium carbide are placed, the boxes being prevented from falling out by means
of the folding covers the nose pieces i¹ of which lie on projections k of a sliding
regulator l.
The regulator is connected with a lever mechanism n n¹ by means of a pin m or
the like; this mechanism rotating round the pivot o. If there be a diminution in
the quantity of gas in the gasometer a projection or pin p on the rod p¹ which is
connected with the gasometer presses against the lever mechanism n n¹ causing it to
rotate around o in the direction of the arrow and to produce a movement of the
regulator thus moving the projection of the regulator 1, which are located below
the cover nose pieces to keep the covers closed, into a new position in relation to
the cover nose-pieces and allowing of the unfolding of all the covers and a falling
down of the whole carbide holders.

page_text: In order, however, that the falling of the carbide holders into the generator may
be effected only gradually and proportionately to the diminution of gas in the
gasometer, the projections k on the regulator / are increased in size continuously in
the direction of the gasometer, or eccentrically arranged of different widths and at
different distances apart, so that the sinking of the gasometer bell at any time only
causes one of the carbide holders to fall into the generator, as in consequence of the
generation of gas which immediately ensues, the gasometer ascends again.
As shown by Figs 2 and 3 several cases g for holding the calcium carbide reservoirs
may be provided.
When several cases are used the opening of the covers in succession is effected by
the pushing or displacement of two regulators 1, 1, the regulator being actuated
by a projecting piece 12 on the regulator l. In the modification shown in Fig. 4 the
displacement of the regulator or regulators and is effected by pressure. For this
purpose the gasometer or a guide rod branching off therefrom is furnished with an
obliquely shaped additional piece or projection which presses against a rollers of
the one regulator. The projections of the other regulator or regulators must only
stand in reversed position below the cover nose-pieces as in the case of the first
described form of carrying out the invention.
Having now particularly described and ascertained the nature of my said.
invention and in what manner the same is to be performed, declare that what
I claim is
1. In an acetylene gas apparatus, an apparatus which automatically regulates the
fall of calcium carbide into the generator in such a manner that the sinking of the
gasometer bell effects, with the assistance of a lever mechanism, the movement of a
regulator or provided with projections, of different widths or at different distances
apart below the cover nose-pieces for effecting the closing of the covers of a case
containing the calcium carbide holders, substantially as described.
2. A further form or modification of the apparatus for automatically regulating the
supply of the calcium carbide mentioned under Claim 1, in which the regulator
or is actuated by pressure through an additional piece r, from the gasometer,
substantially as described.
