An Improved Arrangement of Apparatus for Evaporating Liquids in
Closed Places for Inhalation Purposes.
I, FRANZ HARTMANN, of Hallein, Austria, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved arrangement of apparatus for evaporating
liquids in closed places for inhalation purposes, and whereby the evaporation is very
rapidly effected and the volatile matters to be inhaled are brought to a state of very
fine division.
The improved apparatus consists mainly of a frame serving as a support for
branches, brushwood, straw or the like, over and down which a thin stream or
streams of the liquid to be evaporated is or are caused to flow, and whereby the
liquid, in its descent, is spread in a very thin film-like condition over a very large
extent of surface, whereby it is caused to be rapidly evaporated as aforesaid.
In the accompanying drawings,
Fig. 1. represents a perspective view of the apparatus; and
Fig. 2. represents a variation or modified form of the container of the liquid to
be evaporated.
a, represents the said supporting frame, which may be made entire or as a folding
frame, but is preferably so made as to be capable of being easily taken to pieces.
It is constructed with uprights a, which may be vertically disposed or inclined
towards one another, stayed by cross bars b, and adapted to support at their upper
ends a plate or frame c, which, in turn, serves to support a vessel d, containing the
liquid to be evaporated.
At suitable intervals, the uprights a, are pierced with holes a', or are otherwise
equivalently adapted to support branches of trees-particularly of the coniferæ
order, or brushwood, or straw, or the like in such a manner as to cause the branches
or the like to extend into the space bounded by the supporting frame, so as to form
a body f, below the container d, and within said space, which presents a large
extent of surface to the liquid to be evaporated.
The liquid container d, may be of a bowl-like form, as represented, or of any
other convenient or suitable shape, and is fitted below the level of the plate c and
above that of the body f, with a tubular extension which is perforated with tine
apertures serving to distribute the liquid to be evaporated in fine streams generally
over the body; over and down which it then spreads, dripping from layer to
layer, thus becoming exposed and spread over a very large extent of surface, so
that rapid evaporation thereof ensues and the air of the locality becomes quickly
saturated with the volatile material to be inhaled.
Any unevaporated liquid dripping from the body f, may be collected in a dish or
vessel into which the apparatus may be set, and which may be fitted with a waste
pipe g', enabling such liquid to be readily drawn off and replaced in the container d,
9,
for re-use.
As will be readily understood, this apparatus may readily be set-up, and can be
as readily taken apart, and permits of ready exchange or renewal of the parts of
the liquid distributing bade f

An Improved Arrangement of Apparatus for Evaporating Liquids in
Closed Places for Inhalation Purposes.
1, FRANZ HARTMANN, of Hallein, 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 :-
This invention relates to an improvel arrangement of apparatus for evaporating
liquids in closed places for inhalation purposes, and whereby the evaporation is
very rapidly effected and the volatile matters to be inhaled are brought to a state
of very fine division.
The improved apparatus consists, mainly, of a frame serving as a support to
branches, brushwood, straw or the like, over and down which a thin stream or
streams of the liquid to be evaporated is or are caused to flow, and whereby the
liquid, in its descent, is spread in a thin film-like condition over a large extent of
surface, whereby it is caused to be rapidly evaporated as aforesaid.
On the drawings accompanying my Provisional Specification,
Fig. 1, represents a perspective view of the apparatus, and
Fig. 2, represents a variation or a modified form of the container of the liquid to
be evaporated.
a, represents the said supporting frame, which may be made entire or as a folding
frame, and is preferably so made as to be capable of being easily taken to pieces.
It is constructed with uprights a, (which may be vertically disposed or inclined
towards one another) stayel by cross bars b, and adapted to support, at their upper
ends, a plate or frame c, which, in turn, serves to support a vessel d, for containing
the liquid to be evaporated.
At suitable intervals, the uprights a, are pierced with holes a', or are otherwise
equivalently adapted to support branches of trees, particularly of the coniferæ
order, or brushwood, or straw or the like, in such a manner as to cause the branches
or the like to extend into the space bounded by the supporting frame, so as to form a
body f, below the container d, and within said space, which presents a relatively
large extent of surface of the liquid to be evaporated.
The liquid container d, may be of a bowl-like form, as representel, or of any
other convenient or suitable shape, and is fitted, below the level of the plate c, and
above that of the body f, with a tubular extension d', which is perforated with fine
apertures serving to distribute the liquid to be evaporated in fine streams generally
over the body, over and down which it then spreads, dripping from layer to layer,
thus becoming exposed over a very large extent of surface, so that rapid evaporation
thereof ensues and the air of the locality becomes quickly saturated with the volatile
material to be inhaled.
Any unevaporated liquid dripping from the body f, may be collected in a dish or
vessel 9, in which the apparatus may be set, and which may be fitted with a waste
pipe g, for enabling such liquid to be readily drawn off and replaced in the
container d, for re-use.
As will be readily understood, this apparatus may be readily set up, and can be

page_text: as readily taken apart; and it permits of ready exchange or renewal of the parts
of the liquid distributing body f
The detrimental effect of acids on existing forms of vaporising apparatus, is
entirely obviated in the abovedescribed improved apparatus.
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:-
The herein before described apparatus for rapidly evaporating inhalation liquids,
the same being characterized by a body f, consisting of branches, brushwood, straw
or the like, supported by the uprights of a frame a, adapted to carry a vessel d,
from which the liquid to be evaporated descends and is distributed generally over
the bodyf, by which the liquid is spread in thin films over a relatively large
extent of surface and its evaporation is facilitated, as set forth.
