An Improved Process for Producing Gas for Burning and
Lightening Purposes.
We, KASIMIR STATTLER, of 32, Heimgasse, Metal Caster, and ANTON STREJZ, of
49, Himbergerstrasse, Manufacturer, both in Vienna, in the Empire of Austria, do
hereby declare the nature of this invention to be as follows:-
Acetylene gas has been used hitherto for lightening purposes, but it had the
inconvenience that the gas could be burnt incompletely under deployment of a
disagreeable odour, smoke and soot in spite of all perfections of the process and the
appertaining apparatuses and lamps.

Our invention relates to a process for mixing the acetylene gas with other gases in
order to rarefy or dilute the acetylene gas so that it may burn in any burner with a
brilliant flame without any smoke and soot.
Besides by this rarefaction the danger of explosion is less than with pure
acetylene. This is produced by mixing to the carbide of calcium such substances
from which produces carbonic acid.
Many experiments have proved that such a gas for burning and lighting purposes,
can be obtained by mixing to the carbide of calcium, calcium bitartaricum and tartrate
of potash or bicarbonate of soda and tartaric acid, or any other substances
from which carbonic acid may be obtained by one, two or several of such substances
and to which mixture is added water in drops.
This admixtion drop by drop is advantageously or preferable to produce as much
gas as is necessary for the combustion.
But when the gasometer or vessel for the reception of gas permits we may add at
once as much water as is necessary for producing the whole desired quantity of gas.
We may also mix one of the substances mentioned above with tartaric acid and
water (instead of carbide calcium) and add to it water and carbide of calcium.

Lightening Purposes.
We, KASIMIR STATTLER, of 32, Heimgasse, Metal Caster, and ANTON STREJZ, of
49, Himbergerstrasse, Manufacturer, both in Vienna, in the Empire of Austria, 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:
Acetylene gas was used hitherto for lightening purposes in a different manner; but it
had always the inconvenience that the gas could be burnt but incompletely under
deployment of a disagreeable odour and under deployment of smoke and soot, in
spite of all perfections of the process and the appertaining apparatus and lamps.
This invention relates to a process for mixing the acetylene gas with pure,
indifferent, not burning gases in order to rarefy or dilute the acetylene gas so that
it may burn in any burner with a brilliant flame without any smoke and soot.
Besides by this rarefaction the explosibility or danger of explosion is less than with
pure acetylene. This rarefaction is produced by admixing to the carbide of calcium
such substances from which produces successively carbonic acid.
.
Many experiments have proved that such a gas for burning and lightening purposes
can be obtained but by admixing to the carbide of calcium: calciumbitartaricum and
tartrate of potash or bicarbonate of soda and tartaric acid or any other substances
containing carbonic acid, from which carbonic acid is successively produced, and to
which admixture is added water by and by in drops. This admixion drop by drop is
advantageously or preferable to produce but as much of gas as is necessary for the
successive combustion.
...
But when the gasometer or vessel for the reception of gas permits we may add at
once as much water as is necessary for producing the whole desired quantity of gas.
We may also mix one of the substances mentioned above that is, tartaric acid with
the water (instead with calcium carbide) and add it with the water by and by to the
carbide of calcium. We prefer the following proportions: for one pound carbide
of calcium 2 grains of calcium bitartaricum and 2 grains of tartrate of potash, or
2 grains bicarbonate of soda and 2 grains of tartaric acid, that is, 4-4 grains
of these substances for each pound of carbide of calcium.
When we employ more than two substances we must observe also these proportions.
For three substances we take (when tartaric acid is omitted) 4 grains of the other
substances together, that is, 2 grains from the one and 1 grain of each of the other
ones, when we employ tartaric acid and omit one of the other substances, we take
1 to 1 grains of each of the substances; when we employ all substances, we take
1-1 grains of tartaric acid and 1 grain of each of the other substances.
When we employ besides other substances, we observe nearly the same proportions.
But it is obvious that these proportions may be varied at will without departing from
the nature of this invention.
Having now particularly described and ascertained the the nature of my said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. A process for producing an improved gas for burning and lightening purposes,
burning without smoke and odour with a brilliant flame consisting in rarefying the
acetylene gas by mixing with pure indifferent not burning gases, which rarefaction
is obtained by adding to the carbide of calcium two, three or more of the following
substances: calciumbitartaricum, tartrate of potash, bicarbonate of soda, tartaric

page_text: acid, or any other substances from which produces successively carbonic acid, and
where the gas is produced by the simultaneous or separate admixing of water,
substantially as described for the purpose specified.
2. In a process for producing gas for burning and lightening purposes, the
combination of the various proportions of the ingredients, substantially as fully
described in the above specification for the purpose specified.
