Method of and Apparatus for the Automatic Supply or Delivery of
Perfume and similar Liquids by Means of Internal Pressure.
I, AUGUST HAUSDORF of Tiefenbach, Böhmen, in the Empire of Germany,
Doctor, 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 present invention relates to a method of and apparatus for the automatic
supply or delivery of perfume or similar liquids such as for example hair-wash
as employed by hair-dressers, fluids or liquids for disinfecting purposes etc.
The said apparatus is simple in construction and cheap and easy to manufacture.
The improved apparatus is illustrated by the accompanying drawings in
which :-
Fig. 1 is an elevation-partly in section-of one arrangement of the same, and
Fig. 2 is a section taken along the line - of Fig. 1.
The apparatus consists of a vessel a made of any suitable material such as thin
glass or metal which is formed or provided with a hollow extension b of any
desired shape. This extension has a fine perforation and has inserted in it a
plug or stopper d. The latter is (advantageously) ground in and is formed with
a slot or groove e which can be caused to coincide or communicate with the
perforation by rotating the plug about its longitudinal axis, whereby the interior
of the vessel a is placed in communication with the passage or outlet c and
consequently with the atmosphere.
The liquid (such as perfume, disinfectants etc.) to be supplied or delivered is.
placed in the vessel a, and is mixed with a suitabe quantity of ether.
On now taking the vessel a in the hand, and bringing the groove e in the plug
into connection with the perforation in the extension b the animal heat of the
hand will cause the ether to become vaporised and the ether gases or vapours will
exert a pressure upon the liquid contained in the vessel a in such a manner as to
cause said liquid to be ejected through the groove e and aperture c.
It is to be clearly understood that the vessel a and the extension b may be of
any desired form and that the accompanying drawings are merely illustrative of
one particular arrangement of the apparatus.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is --
1. The hereindescribed method of automatically supplying or delivering perfume
and similar liquids by means of internal pressure by mixing the liquid to be
delivered with a suitable quantity of ether which is caused to become vaporized
by the animal heat of the hand and acts to expel the liquid from out of a vessel
substantially in the manner and for the purposes herein before set forth.
2. An apparatus or device consisting of a vessel such as a having an extension
such as b formed with a perforation such as c and in which extension there is
fitted (by grinding in) a plug d provided with a groove or slot such as e said groove
being adapted and arranged by rotation of the plug about its longitudinal axis to
be brought into coincidence or connection with the perforation c of the extension b
so as to form communication between the interior of the vessel and the outer air

illustrated by way of example in the drawings hereunto annexed.
