Complete Specification Left, 19th Jan., 1900-Accepted, 10th Mar., 1900
I, EDMOND PESTEL, of Crony, in the Department of Aisne, in the Republic of
France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide a simple and efficient acetylene gas
apparatus, and the invention consists in a generator and a holder of special
construction, which may be arranged separately from one another, or combined
together, one within the other.
In carrying out the invention, I provide a vessel to contain water or other
suitable liquid, and which is capable of being closed with a gas-tight cover.
Through this cover a charging tube for, say, calcium carbide, is inserted, which
extends downwards into the liquid, and is provided at bottom with an inclined
shield.
The vessel is provided at the side with a gauge glass, which also serves as a
relief valve in case of need, and at top with a pipe by which the gas produced
is conveyed to the holder.
This holder consists of a reservoir or tank, and a hell or gas holder. At the
bottom of the tank is a closed box, which is termed a washer. This box is con-
nected with the pipe from the generator by a coil surrounding the bell, this end
of the coil forming a dip pipe, which dips into a sealing liquid in the box.
The box is provided with a filling pipe for the sealing liquid from outside the
tank, and with a gas-outlet pipe entering the bell, above the level of the sealing
water in the tank.
An outlet or service pipe also projects into the bell, above the seal water
level.
All the vessels and tanks will be provided with suitable means for discharging
their contents when desired.

Improvements in Acetylene Gas Apparatus.
I, EDMOND PESTEL, of Crony, in the Department of Aisne, in the Republic of
France, Manufacturer, 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 that class of apparatus in which acetylene gas is
generated, by making use of the well-known reaction of water, or an aqueous
liquid, upon an alkaline-earth carbide, such as carbide of calcium.
The object of this invention is to provide a simple and efficient acetylene gas

page_text: apparatus, and the invention consists in a generator and a holder of special
construction, which may be arranged separately from one another, or combined
together, one within the other.
In the accompanying drawings, which partake somewhat of the nature of
diagrams,
Fig. 1 shows one type of my apparatus, consisting in the generator and gas-
holder separate; and
Fig. 2 a second type of apparatus, with the generator and gasholder combined
together.
The generator is composed of a receiver A, suitably supported upon legs a,
and capable of being closed by a cover B, secured by means of the bar and screw b
or by any other means.
The cover B is traversed by a tube of fairly large diameter C, penetrating into
the interior of the receiver a certain distance below the surface of the liquid,
which the receiver holds, and which serves for the introduction of the carbide,
when required.
At its lower extremity, the tube carries an inclined piece c, forming a screen,
and preventing the bubbles of gas from escaping by the tube C, vet allowing the
carbide, which is introduced by its upper end, to fall into the interior of the
receiver A. At one point in its side, the receiver is provided with an open-
ended tube D, which serves to shew the height of the liquid in the inside, and
serves also as a safety valve in case of an abnormal production of gas.
The receiver A is provided, at its lower end, with an emptying device a', which
serves to empty the water and the residue of the reaction.
The gasholder is formed of a vessel E, and a bell F; the gas coming from the
generator, traverses first a spiral G immersed in the water of the vessel E, then
bubbles through the washer H, and is conducted by the tube h into the bell F.
This washer H can, by means of the tube ¹ be filled with water, or a suitable
washing liquid, provided to purify the gas. It can be emptied by a tube ²;
the gas which fills the hell Fescapes by a tube I to the mains or services. The
bell F is provided with a manometer M, and the vessel E can be emptied by an
opening provided with a plug N.
In my second type of apparatus the generator and the gasholder are united
in a single apparatus.
The generator consists of an annular vessel A1; the central portion G¹ thus
formed, constitutes the vessel of the gasholder
The introduction tube for the carbide has a position identical with that which
it has in my first type of apparatus. It is placed at some point in the cover
of the annular vessel, and carries a screw to prevent the exit of the bubbles of
gas. The rest of the apparatus, the working of the gasholder, the spiral for
cooling, the washer, etc., are identical with those in the first model.
I would here remark with regard to my system of apparatus that I do not
intend to confine myself to the exact details of construction above described, as
any changes which do not alter the general arrangement may be made. It is,
for instance, possible to have a plurality of tubes for the introduction of the
carbide, and the upper end of these tubes may be closed in any suitable manner.
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-
An acetylene gas-producing apparatus substantially as above described with
reference to the accompanying drawings.
