COMPLETE SPECIFICATION.
Apparatus for Production of Acetylene Gas.
REGINALD HADDAN of the Firm of Herbert Haddan & Co. Patent
Agents, of 18 Buckingham Street Strand W.C. London in the County of
Middlesex do hereby declare the nature of this invention a communication to
me from abroad by Aniano Boter known as Aniano Boter y Carreras of Barcelona
in the Kingdom of Spain Manufacturer 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 an apparatus for the production of acetylene gas by
the reaction of water upon calcium carbide in such a manner that the quantity of
calcium carbide which must be brought into the water is previously micasured for
producing in an intermittent manner determined quantities of the gas as wanted
for use.
Referring to the drawings
Fig. 1 is an elevation partly in section of the apparatus.
Figs. 2 and 3 are detail views of modifications.
a closed receiver A
The apparatus is composed of a gas-generator formed by
which encloses in its interior another receiver B B for the water necessary for the
production of the gas. At C in the interior of the apparatus and above the
receiver B is arranged a support formed by horizontal and inclined boards in
such a
manner that there is alternately a horizontal and an inclined board.
Upon each of the horizontal boards a is placed a parcel P which encloses a
determined quantity of calcium carbide.
The cover of the receiver A is traversed by an axle D on the upper part of
which is arranged a ratchet wheel E; on the under part of the axle D and in the
interior of the apparatus is fixed a rotatory arm or rod F.
G is the bell of the gas holder for the gas produced; this bell carries an
arm H H' the part H' of which is bent and provided with a slit in which is engaged
the gudgeon of the rotatory lever K¹ which forms the pawl of the wheel E.
The gas generator is connected with the gas holder by the pipe I; the gas
holder is connected with the supply pipe by the pipe 1.
The operation of the apparatus is as follows;-
On each of the horizontal boards a is placed a parcel P which contains a
determined quantity of calcium carbide and in the interior of the receiver B is put
a determined quantity of this carbide; the production of acetylene gas begins and
passes through the pipe I fills the gas-holder G in order to be carried away
through the pipe I¹; when the gas being used allows the bell of the gas holder to
sink, the slide H¹ operates the gudgeon K the lever K turns the wheel E and the
rod F pushes one of the parcels P upon the next inclined board 6 whence it falls
into the water contained in the receiver P, producing thus a new quantity of
acetylene gas which lifts the bell G; the arm H' operates the gudgeon K in the
contrary direction moving the lever K¹ over the next tooth of the wheel E which
is held from revolving backwards by the pawl O. When the bell G again sinks to
a certain limit another parcel P falls and thus successively until the wheel E has
made a complete revolution.
The parcels P could be replaced by boxes containing the carbide, or by any
other analogous system. A mechanism as shown in Fig. 2 might be used consisting
of a box M which can turn round the trunnions Q and which is retained by the
bar R K. A certain number of these boxes filled with carbide beiug arranged in

page_text: the gas generator A. the arm F by lowering the bars RR' allows the boxes to fall
over successively and empty their contents of carbide into the water receiver.
In Fig. 3 is shown another box arrangement; in this case the bottom of the box
is hinged at Z and is provided with a projection X which can be retained by the
hook at the extremity of a lever operated at the other extremity by the arm F
of the gas generator. In the two boxes Figs. 2 and 3 carbide can be placed in
pieces or in mass formed previously.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
An apparatus for the production of acetylene gas provided with mechanism
causing up and down movement of the bell of a gasometer to produce rotatory
movements of a rod or lever placed in the interior of a gas generator and causing
the successive falling of determined quantities of carbide of calcium into the water
contained in the interior of the said gas generator all substantially as described aud
illustrated and for the purpose set forth.
Dated this 23rd day of July 1896.
