COMPLETE SPECIFICATION.
Process and Apparatus for the Production of Carburetted Air for
Incandescent Gas Light.
I, OSCAR KAINS, Bismarck Strasse 24, Hamburg, in the German Empire,
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 :-
The object of the present application is an invention by means of which a
rational lighting, totally independent of the gas-works, is attained in a simple,
easy safe and inexpensive manner.
The Hillenbrand's apparatus is made use of for the production of a sufficient
and uniform current of air for the mixture of the combustible vapours with the
carburetted air, in which apparatus a vacuum is produced by water, which enters
automatically at regular intervals. The outer air enters the vacuum, to thereupon
flow out of a gasometer in a uniform current and under constant pressure to be
lead where required. The mixture of the air current with the carburetted
hydrogen vapours is effected by passing the air current through a specially arranged
apparatus. This apparatus is shown in the annexed drawing, in which
Figure 1 shows the apparatus in a longitudinal section.
Figure 2 shows diagrammatically, the arrangement of the lighting plant
A series of chambers a are arranged in this apparatus, the walls or partitions
of which consist of wick-like absorbent woollen or other suitable fabric b which
absorbs the carburetted liquid, and imparts the vapours to the current of air passing
through the chambers.
A cheap product of petroleum refining, the specific gravity of which is 0.71,
is used as carburetted liquid. The apparatus consists of a hermetically closed
tank c preferably of sheet galvanized iron; wires d to which the above mentioned
wicks bare fastened, hanging down to the bottom of the said tank, a further layer
of wicks e being provided on top of the said wires. The air produced in Hillen-
brand's apparatus enters by means of the admission tube f into the apparatus, passes
through all the chambers and wick-like fabrics and leaves the apparatus through
the outlet or gas tube g in the form of a combustible gas. The carburetted liquid
is led into the apparatus either by the admission tube f or by a special admission
tube.
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 herein described process for the production of carburetted air for in-
candescent gas light, consisting in leading a current of air, which has been
produced in a suitable apparatus, through a tank whereby it becomes saturated
with combustible carburetted hydrogen vapours by passing through absorbent
fabric, saturated with a carburetted liquid, and from thence led to the place of
consumption as described and set forth.

page_text: 2. The nerein described apparatus used in connection with the process claimed
in Claim 1, consisting in a hermetically closed tank in which an absorbent wick-
like fabric is suspended at suitable intervals, the said tank being provided at
either end thereof with an inlet and outlet pipe substantially as herein described
and set forth.
