Improved Acetylene Gas Apparatus.
I, GUSTAV JACOBI, of No. 67, Holbein Strasse, Dresden, in the German Empire,
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 :—
My invention relates to an improved acetylene gas apparatus in which liquid
carbonic acid is made use of as the source of pressure and for the purpose of spraying
the water supply. In the process of lighting by aid of acetylene gas an essential
feature consists in the uniform supply of water to the generator, because the
development of gas from the carbide depends directly from the quantity of water
supplied. In apparatuses in which the supply of water takes place from above
through its own gravity, or in which the internal gas pressure regulates the supply of
water automatically, the development of gas is always irregular. In my improved
apparatus I make use of liquid carbonic acid as the motive force for the supply of
water. My apparatus consists of a generator B preferably of copper and tinned
inside, the lower cylindrical shaped part whereof stands in another vessel, which
vessel is filled with water. The vessel B is provided with a safety valve. The supply
of carbide to the vessel B is effected from above through a large opening. The
carbide is placed in a perforated container of tinned iron and this is then placed in
the cylindrical part of the vessel B. The opening can then be closed by means of a
lid which is fastened tightly down by means of screws or the like. The apparatus is
operated when the cock of the carbonic acid container is opened. The carbonic acid
then passes into the tube t. This tube t has two branches each provided with a stop
cock in order to regulate the admission of carbonic acid. One branch shown as the
left branch in the drawing passes down into the copper cylinder A. The carbonic
acid exercises pressure upon the water in this cylinder and forces it through the said
tuber into the generator B, the quantity being regulated by means of the stop cock.
The right limb of the tube t passes into the generator B. Before entering the
generator the tube t unites with the water tube r.
The combined part of the tube indicated in the drawing with the letter o is jointed
at the bend f so that the tube can be moved to one side when the generator B is to
be filled with carbide. At the end of the tube o the same is provided with a funnel-
shaped opening. The carbonic acid passing into the water divides the same and
distributes it over the carbide. The gas which is generated thereby passes into the
cylinder C, which is filled for one third of its depth with glass wool and has for its
object to arrest any solid or liquid substances carried away mechanically with the gas.
The gas then passes on through a number of ordinary gas pipes which are arranged
vertically upon a larger tube in order to effect the cooling of the gas.
condensed water runs off through an inclined pipe into a collecting vessel. Finally
the gas passes into the gasometer G. This gasometer possesses a manometer and is
provided with a container below for any condensed water which may collect therein.
The
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. Improved automatic apparatus for the production of acetylene gas, characterized
by the arrangement that liquid carbonic acid, escaping at a uniform pressure, forces

page_text: water out of a vessel into the gas generator, whilst at the same time a branch stream
of carbonic acid passes into the water before its entrance into the generator dividing
and distributing the same and spreading it uniformly over the carbide; the supply
of the said carbonic acid and water through the various tubes being regulated by
stop cocks, and the discharge upon the carbide effected through a funnel shaped
terminal piece on the tube so placed that it can be turned aside whilst the apparatus
is being filled with carbide; the whole arrangement being devised to secure that in a
given time the same quantity of water will always be supplied to the carbide so that
the quantity of gas produced will remain constant.
2. The improved apparatus for the production of acetylene gas by aid of water and
carbonic acid constructed and operating substantially as above described with reference
to the accompanying drawing.
