page_text: Improvements in Apparatus for Generating acetylene Gas.
I, JEAN REIBEL, of 24, Rue de Lavalette, Angouleme, in the Republic of
France, Builder, do hereby declare the nature of my said invention to be as
follows:
-
This invention relates to an apparatus for generating acetylene gas without
any appreciable development of heat and in an automatic manner, to suit the
demand of gas required for use.
The first point is achieved by causing the carbide fragments to fall, one by one,
into a large volume of water.
The second point is attained by a simple transmission device controlled by the
descent of the bell shaped slide cover of the gas holder.
The apparatus comprises a gas generator and a gas holder.
The gas generator is composed of two sheet iron boxes of parallelopiped shape
placed on top of one another with an interposed layer of felt.
The gas holder comprises a cylindrical receptacle and a cylindrical slide cover.
An interior tube, arranged along the axis of the slide cover, serves for carrying
off the gas.
The carbide is enclosed in a receptacle, which has the shape of a truncated
rectangular pyramid. This extension in a downward direction is necessary, in
order to prevent the fragments from being wedged up as they descend. The
carbide rests upon the curved sheet iron base of the receptacle and, subsequently
passes upon an endless leather band passing over rollers movable around their
axes. The sections radiating about a point gradually increase in the downward
direction.
The endless leather band serves to draw the carbide toward the discharge
opening. As the carbide is drawn along, it arrives between two guides the
distance of which from one another increases gradually toward the discharge
orifice.
The carbide fragments fall into the box and pass into a conduit which conveys
them right into the water.
In this box a large volume of water is stored. If no special provision were
made, the moisture set free by evaporation and passing through the orifice, would

against by pouring into the conduit on top of the water, a liquid of lesser density
and not subject to act upon the carbide. The liquid chosen for the apparatus,
herein described, is petroleum-oil.
The conduit has two angular bends. Thus, when the carbide comes in contact
with the water, the disengaged gas is prevented from leaving through the orifice.
A few bubbles; only, traverse the petroleum layer. The remainder escapes above
the water surface.
The gas is collected at the upper part of the cylinder by means of a tube.
This tube which is made sufficiently wide to avoid variations of pressure in the
generator re-descends across the volume of water.
The communication between the gas meter and the gas generator is established
by means of an india rubber tube.
The automatic device comprises: 1. The endless leather band and its support.
2. The transmission device.
The support for the endless leather band is composed of a series of rollers
turning on points, and of one larger roller, the whole supported by a cast iron
frame; a tightening roller ensures the adherence between the large roller and the
endless leather band. On the axis of this roller a ratchet wheel is keyed.
The ratchet wheel is moved by a pawl carried. by a lever. The movement of
the bell shaped slide cover is transmitted to the lever by means of a connecting
rod. In order to attain that the movement of the endless leather band may not
commence, until the bell shaped slide cover in its descending movement has
reached a certain point, the connecting rod is provided at its lower part with a
slotted guide, and the lever is stopped at one point of its course by a catch.

The lever is likewise provided with a slot-guide which permits of adjusting the
lengths of the lever arm.
The upper box carries besides the carbide receptacle two cylindrical receivers.
The small receiver which is closed by a screw plug, serves for the introduction
of petroleum oil into the gas generator by means of a cock, and tube.
The larger receiver serves for the introduction of water by means of a tube and
cock. At the bottom of the box a discharge cock of the same dimension as the
cock in the water pipe is arranged, which serves to expel the water charged with
lime and impurities.
In order to fill the gas generator with fresh water, it is only necessary to
open the said cocks.

fitted and adjusted to each other by means of screws and bolts, ensuring a tight

I, JEAN REIBEL, of 24, Rue de Lavalette, Angouleme, in the Republic of
France, Builder, 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 an apparatus for generating acetylene gas without

demand of gas required for use.

The second point is attained by a simple transmission device controlled by the
descent of the bell shaped slide cover of the gas holder.
The apparatus comprises a gas generator and a gas
illustrated in the accompanying" sheet of drawings in which
Figure 1 is an elevational view of the entire apparatus.
Figure 2 a vertical section on line X Y Figure 1.
Figure 3a horizontal section on line & y Figure 2, and
Figures 4 and 5 are details hereinafter referred to.

The gas generator is composed of two sheet iron boxes B and B of parallelo-
piped shape placed on top of one another with an interposed layer of felt.
The gas holder comprises a cylindrical receptacle and a cylindrical slide cover.
An interior tube, arranged along the axis of the slide cover, and which has its
feed opening at K, serves for carrying off the gas.
The carbide is enclosed in a receptacle A, which has the shape of a truncated
rectangular pyramid. This extension in a downward direction is necessary, in
order to prevent the fragments from being wedged up as they descend. The
carbide rests upon the curved sheet iron base a and subsequently falls upon an
endless leather band y passing over rollers R, r, r
rmovable around
their axes v. The sections of the passage way open to the carbide, radiating about
point o Figure 2 gradually increase in the downward direction.
The endless leather band y serves to draw the carbide toward the discharge
opening O. As the 'carbide is drawn along, it arrives between two guides G G¹
Figure 3, the distance of which from one another increases gradually toward the
discharge orifice':'
The carbide fragments fall into the box B' and pass into a conduit C C which
conveys them right into the water.
In this box B₁ a large volume of water is stored. If no special provision
were made, the moisture, set free by evaporation and passing through the orifice O,
would attack the carbide, contained in the box B. This inconvenience is, however,
guarded against by pouring into the conduit C C, on top of the water, a liquid
of lesser density, and not subject to act upon the carbide. The liquid chosen for
the apparatus, herein described, is petroleum-oil.
The conduit C C has two angular bends. Thus, when the carbide comes in
contact with the water, the disengaged gas is prevented from leaving through
the orifice 0: A few bubbles only, traverse the petroleum layer at O¹. The
remainder escapes above the water surface:
The gas is collected at the upper part of the cylinder H, by means of the tube T.
This tube which is made sufficiently wide to avoid variations of pressure in the
generator, re-descends across the volume of water.

page_text: The communication between the gas meter and the gas generator is established
by means of an india rubber tube 0.
The automatic device comprises: 1. The endless leather band y and its support.
2. The transmission device.
The support for the endless leather band is composed of a series of rollers r
turning on points t, and of one larger roller R, the whole supported by a cast
iron frame; a tightening roller l ensures the adherence between the large roller R
and the endless leather band. On the axis Z of this roller R a ratchet wheel is
keved.
The ratchet Z is moved by a pawl I, carried by a lever Figure 4. The movement
of the bell shaped slide cover is transmitted to the lever P₁ by means of a
connecting rod P. In order to attain that the movement of the endless leather
band may not commence, until the bell shaped slide cover in its descending move-
ment has reached a certain point, the connecting rod P is provided at its lower
part with a slotted guide, and the lever P1 is stopped at one point of its course
by a catch u. A counterweight, n has the tendency of constantly bearing against
this catch.
The lever P¹ is likewise provided with a slot-guide which permits of adjusting
the length of the lever arm.
The upper box B carries besides the carbide receptacle A two cylindrical
receivers D and D¹.
The small receiver D' which is closed by a screw plug, serves for the introduc-
tion of petroleum oil into the gas generator by means of a cock, and a tube t¹.
The large receiver D serves for the introduction of water by means of the tube t
and cock V. At the bottom of the box B₁ a discharge cock V₁ of the same
dimension as the cock in the water pipe V is arranged, which serves to expel the
water charged with lime and impurities.
In order to fill the gas generator with fresh water, it is only necessary to open
the said cocks V and V¹.
The guides which serve to prevent the carbide fragments from falling to the
right or the left of the endless leather band, are made of sheet iron, Figure 5,
their lower part engaging with the orifice O, and the flanges s with grooves, pro-
vided in the upper part of the box B.
A double gauge N, communicating with the water and the petroleum, indicates
externally, their respective levels.
The overflow L is formed by a fixed tube provided with another tube l¹
which fits under friction into the former. This overflow device--in the case of
a generator of large yield-admits of a constant water current being supplied to
the generator.
The generator can be completely taken to pieces. All the constituent parts
are fitted and adjusted to each other by means of screws and bolts, ensuring a
tight connection between all the parts in contact.
The shape of the different constituent parts of the apparatus may of course be
varied without departing from the spirit of the invention.
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. The process of automatically producing acetylene gas by causing carbide
fragments to fall into the water after having passed through a liquid presenting
an inactive quality upon carbide, which latter liquid prevents the wet steam from
attacking the main bulk of the carbide not at once employed at the time of the
working.
2. The automatic device for carrying along the carbide fragments, consisting
of an endless belt, supported on rollers turning about their axes, the said belt

page_text: being moved by a lever, actuated by the descending movement of the bell shaped
slide cover of the gas-holder.
3. The apparatus for manufacturing acetylene gas substantially as described
with reference to the accompanying drawing.
