Improvements in Connecting the Carbide Reservoirs of Acetylene
Gas Generators.
I, WILHELM SCHUBERT, of No. 61, Adalbert Strasse, in the City of Berlin, in
the Kingdom of Prussia, and German Empire, Civil Engineer, 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:-
Most acetylene gas apparatuses are, as is well known, of complicated construc-
tion. The reason for this is, that in order to enable the gas to be generated
continuously, the generating apparatus must be so constructed, that immediately
one carbide reservoir is emptied, another can be set in its place.
According to the present invention the carbide reservoir is connected with the
gas-holder proper by means of short pipes, caused to firmly press one against the
other, and so make a tight joint, by means of a bayonet joint coupling device.
The arrangement is such that the carbide reservoir can be disconnected from
the gas-holder by a single manipulation, and another reservoir substituted..
On the accompanying drawing an acetylene gas generator is shown provided
with the new arrangement.
Fig. 1 is an elevation, and
Fig. 2 a vertical section of the apparatus.
The gas-holder proper consists of a vessel a, divided by a partition wall 6 into
two chambers, a water chamber e and a gas chamber d. These two chambers are
connected together by a pipe c¹, the gas from the chamber being led away to
the place of consumption through the pipe . f is a short pipe, provided with
a screw cap, through which water may be supplied to the apparatus." e is a water
gauge, fixed in socket pipes communicating with the water chamber c.
The carbide reservoir g (of which two are shown on the drawing, only one,
however, being necessary) consists of a small cylindrical vessel, closed by a
screw cover g, in which is a network basket or the like to hold the carbide. This
basket is supported on brackets, leaving a space below for sediment to collect.
Each of such carbide reservoirs is provided above and below with two short
connection pipes h, k respectively, which fit to and make a close joint with two
similar pipes i, l, fixed on the wall of the gas-holder. All these connections or
pipes are provided with closing devices or cocks h¹, 1, 2, 7, so that when the
latter are turned, there is no communication with the gas chamber. The carbide
reservoir can then be removed without any escape of gas taking place.
packing rings for effecting a tight joint.
are
The water enters the carbide reservoir through the lower passage, and the gas
generated escapes through the upper passage into the gas chamber d.
In order that the joints between the carbide reservoir and gas chamber connec-
tions may be secure, a bayonet joint device is arranged between the two connec-
tion pipes- 7. This consists of a rotary handle m, secured to a bracket affixed to
the wall of the gas chamber; and of a socket », provided with a slot, affixed to the
wall of the carbide reservoir. The said slot is bent round at right angles at its

page_text: inner end, so that when the handle m is pushed in and turned, it passes into the
angular portion of the slot, drawing the gas chamber and carbide reservoir firmly
together, and effecting a tight joint between the parts hi and kl.
To remove the carbide reservoir it is only necessary to turn back the handle m,
when the empty reservoir may at once be replaced by a new one.
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
1 claim is:-
:-
An arrangement for rapidly changing the carbide reservoirs of acetylene gas
generators without escape of gas, consisting in the carbide reservoir and the gas
chamber being each provided with short connecting pipes fitting together and
making a close joint and provided with stop cocks or the like; the said joint being
effected by means of a locking device, comprising an internal member secured
to the one vessel, provided with a rotary handle, fitting into an external member
or socket affixed to the other vessel, provided with a bent slot, whereby on the
parts, being put together, the said. handle and slot engage and form a bayonet joint
fastening, all substantially as and for the purposes hereinbefore set forth.
