An Improved Apparatus for Producing Vapour or Gas from Liquid
Hydrocarbons..
1, ADOLPHE ISIDORE VAN VRIESLAND of 78, Sarphatistraat, Amsterdam in
the Kingdom of Holland, Merchant, 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 has for its object an apparatus for the automatic production of
vapour gas from air and liquid hydrocarbons.
The apparatus is shown in the accompanying drawings in vertical section. The
invention consists essentially as follows:-
A reservoir a is provided in its bottom with a pipe 6 projecting into the reservoir
and serving as an air supply shaft, whilst on the cover a pipe c is arranged having
a narrowed nozzle or exit spout d. A sheath or covering e formed of the most
absorbent material possible is drawn over the air shaft b and projects above the
pipe 6 to a certain extent, sufficient rigidity being given to its upper part by
means of stiffening bars or wires f attached to the shaft to enable it to stand
freely.
'
The reservoir a is filled up to a certain level with liquid hydrocarbon or with a
substance saturated therewith in such a way that the sheath e draws up the hydro-
carbon by capillary attraction and evaporates it into the chamber formed by the
pipe c. Sufficient air is drawn in by means of the pipe b, to produce enough
vapour, the inflowing air during its passage being saturated with hydrocarbon
vapour and the combustible mixture produced escaping from the nozzle d.
The resulting draught has a suction action and thereby assists the evaporation
of the hydrocarbons which is increased by the sheathe having exposed or uncovered
evaporating surfaces at both sides.
i
The upper edge of the air pipe b is somewhat curved inwards in order to prevent
any drops of liquid which may become separated from the sheath e from falling
into the air pipe. Such drops are caught by the inwardly curved edge 9 and again
returned to the sheath e.
If the combustible mixture produced is to be conveyed to a distance, this can be
effected by having a greater difference of level between the air inlet and gas outlet,
that is to say a greater draught, or by conducting air under pressure into the air
shaft b.
The apparatus hereinbefore described may be advantageously employed for
producing vapour or gas in large quantities, as the evaporation of the hydrocarbon
produced on the inner surface of the sheath e by the air under pressure in no way
impedes the free evaporation on the outside of the sheath e, but rather assists the
latter in consequence of its suction action.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for producing vapour or gas from air and liquid hydro-carbons,
characterised by a sheath of absorbent material uncovered at both sides of its
unna

part of the hydrocarbon reservoir allows as much air to enter as is necessary for
producing a suitably combustible gas mixture, substantially as hereinbefore set
::forth.

the improved apparatus for producing vapour or gas from liquid hydrocarbons,
substantially as described and illustrated.
