Improvements in Acetylene Gas-apparatus.
We, ALWIN EUGEN RICHARD SOHNEL, of 111, Lubeckerstrasse, Hamburg,
Electrical Engineer, and AUGUST RICHARD ZEHNER, of 39, Brunnenstrasse, Ham-
burg, 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:-
This invention relates to apparatus for generating acetylene gas more particularly
adapted for use as a lamp in any kind of carriage lantern, which lamp not only
can be extinguished or kindled by turning the gas cock with the same certainty as
can an ordinary gas lamp, but also is so constructed that the inconveniences due
to the troublesome after-evolution of gas are entirely avoided. These objects are
essentially achieved by the use of a cock which passes through the apparatus and
serves both for regulating the admission of water and the exit of gas and for
permitting the escape of the gas which is evolved after the apparatus has been
closed and the flame has been extinguished.
In the accompanying drawing a form of our improved acetylene apparatus is
shewn in section. It will be seen therefrom that the lamp consists of a water
container a provided with a screw-threaded cover A and with a charging tube x.
The container is otherwise completely closed except for the opening g in its bottom,
and is situated immediately above the vessel 6 in the lower part of which the carbide
holder o is fixed by the screw thread n on its lower end. The vessel b contains in
its upper part a purifying apparatus q constructed of perforated material t and
filled with a suitable purifying substance. The two containers and b thus
arranged one above the other are put into communication by means of the cock d
which is rotatable quite gas-tightly in the housing c formed for it in the cover of
the vessel b and the bottom of the vessel a, and may be tightened up by the washer e
and the lock nut f carrying the screw h. The cock has two transverse bores g
and the former serving for the admission of water and the latter for the exit of
gas; the bore
opens into the tube k which passes through the water container
and the cover A thereof and leads to the gas burner. The screw h which passes
through the nut f and through a longitudinal bore in the cock d, serves to regulate
the flow of water.
When the parts are in the relative position shewn in the drawing the water
into the tuber with which it communicates and which
passes through the bore
is fastened to the cover of the vessel b; thence it flows through the distributor p
The evolved gas passes
to be uniformly sprinkled over the carbide in the holder o.
first through the purifier 7 and then through the opening i, corresponding with
the transverse bore through the cock, and so to the burner.
There is a transverse bore through the cock at right angles to and opening
into the transverse bore i. By turning the cock through an angle of 90° this
bore communicates with the gas exit opening of the vessel b and the gas escapes
through the longitudinal bore m opening into the transverse bore i so that on
closing the water and gas passages and extinguishing the flame, the gas which is
afterwards evolved in the vessel b escapes into the open air. When the apparatus

page_text: is at work and the flame kindled the opening of the bore m is closed by the pro
jecting flange s, as will be apparent from the drawing.
This apparatus not only can be used like an ordinary lamp, but also possesses the
further advantage that the water and carbide containers are separate and can be
charged in a room without annoyance from escaping gas.
Furthermore all the parts are completely independent of each other and can
easily be interchanged, a matter of importance in the manufacture of the apparatus.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, we declare that what
we claim is:
―
1. An acetylene gas apparatus consisting of a water container separated from an
interchangeable carbide container, such as
a cock, such as d, serving to regulate the admission of water into and the exit of
by a housing such as c provided with
gas from the carbide holder and to discharge the gas produced after the extinction
of the lamp, substantially as described.
2. In an acetylene gas apparatus such as is referred to in Claim 1, a cock, such
as d, for simultaneously regulating the admission of water into and the exit of
gas from the carbide holder and for discharging the gas produced after the extinc-
tion of the lamp, which cock is rotatable in a housing, such as c and is provided
with two transverse bores, such as g and i, for the passage of water and gas
respectively, the said bore for the passage of gas having opening into it a longi-
tudinal bore such as m, which can be put into communication with the carbide
holder and the outer air to allow of the escape of gas when the passage for the
gas to the burner is closed and can be closed by a flange, such as s, when the passage
for the gas to the burner is opened, substantially as described.
3. In an acetylene gas apparatus such as is referred to in Claims 1
and 2 the arrangement for regulating the flow of water consisting in a pointed
screw, such as h, passing through a longitudinal bore in the cock and entering
the bore for the passage of the water, substantially as described.
