1, KARL SCHULZE, of Weierlingen, in the Empire or Germany, Inysician, do
hereby declare the nature of this invention to be as follows:-
My invention has for its object an improved apparatus for administering suitable
vapours for curing or alleviating diseases of the ear, throat, or other parts of the
body.
The improved apparatus consists of a stand carrying a small vessel or boiler
provided with an opening, closed by a screw or stopper, by which it can be filled,
a safety valve, and two pipes to the outer ends of which india rubber tubes are
fitted.
The boiler is supplied, through the opening described, with a decoction of the
medicinal herbs or other liquid the vapour of which is to be used, and a spirit lamp
in a frame below the boiler is lighted.
As soon as the liquid boils, the outer end of the india rubber tube fitted upon one
of the pipes which leads from the top of the boiler is applied to the car, nose, or
nostrils, or other part to be treated, a suitable nozzle being first fitted upon its
outer end. Or a tube having a very fine bore may be used, (resembling the ordinary
auricular catheter).
The other pipe fixed upon the boiler has its outer end also provided with an
india rubber tube, whilst its inner end dips nearly to the bottom of the boiler.
The outer end of this india rubber tube is provided with an elastic bulb having
above and below it a valve, so that by alternately compressing and releasing the bulb
air is forced through the pipe into the liquid in the boiler, and thence, together with
the vapour with which it becomes saturated, to the part to be treated.
A second equalizing bulb is preferably used above the first. By regulating the
quantity of air, the vapourized air can be supplied more or less warm, and more or
less saturated.
When it is desirable that the vapour should be supplied at a determined and
regular temperature for a certain time, a cup or dish supported upon three feet, and

page_text: nearly filled with sand is fitted into the frame below the boiler, the frame being
heightened by means of a separate ring provided with a handle, so that the bottom of
the boiler dips into the hot sand bath. In this way if the flame below the sand
bath is not too large, the liquid may be maintained at any desired temperature below
boiling point, and an even and regular heat is communicated to the air as it is forced
through the liquid.
In order that any condensed water may not pass through the dischargo nozzle,
a bulb is formed upon the tubo near the latter, which serves as a reservoir for such
water, the pipe from the boiler entering the bulb for a short distance so that the
water cannot flow back.
By the improved apparatus, compressed air saturated with the warm vapour of
the required medicinal decoction is easily and safely supplied to the part to be
treated.

page_text: COMPLETE SPECIFICATION.
An Improved Apparatus for Administering Vapours for Medicinal
Purposes.
I, KARL SCHULZE, of Weferlingen, in the Empire of Germany, Physician, do
hereby declare the naturo 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, and accompanying drawing, (that is to say):
My invention has for its object an improved apparatus for administering suitable
vapours for curing or alleviating diseases of the car, throat, or other parts of the
body by forcibly directing into the nose, or into the outer or inner organs of the ear,
tho vapours, from a decoction of medicinal herbs.
The accompanying drawing is in illustration of my invention, figure 1 being a side
view, figure 2 a section and figure 3 a view from above of the apparatus.
The improved apparatus consists of a stand A carrying a small vessel or boiler B
provided with an opening C closed by a screw or stopper, by which it can be filled a
safety valve D, and two pipes F and G, to the outer end of which india rubber tubes F¹
and G, are fitted as shown in figure 1.
When the apparatus is to be used the boiler B is supplied through the opening C,
with a decoction of the medicinal herbs or other liquid the vapour of which is to
be used, and a spirit lamp E in the stand below the boiler is lighted. As soon as the
liquid in B boils, the outer prolongation H of the tube F' is applied to the ear, nose,
or nostrils, or other part to be treated, a suitable nozzle being first fitted upon its
outer end. Or an induction tube having a fine boro may be used, (resembling the
ordinary auricular catheter) and shown in figure 4.
The other pipo G fixed to the boiler has its outer end also provided with an india
rubber tube G, whilst its inner end dips nearly to the bottom of the boiler. The
outer end of this india rubber tube G' is provided with an elastic bulb having above
and below it a valve, so that by alternately compressing and releasing the bulb air
is forced through the pipe G into the liquid in the boiler B, and thence through F, F,
and H, together with the vapour with which it becomes saturated, to the part to be
treated. A second equalizing bulb is preferably used above the first.
By regulating the quantity of air, the vaporized air can bo supplied more or less
warm, and more or less saturated.
When it is desireable that the vapour should be supplied at a determined and
regular temperature for a certain time a cup or dish (shewn in figure 5) supported
upon three feet, and nearly filled with sand is fitted into the frame below the boiler,
the stand A being heightened by means of a separate ring provided with a handle
(as shewn in figure 6); so that the bottom of the boiler dips into the hot sand bath.
In this way, if the flame below the sand bath is not too large, the liquid may be
maintained at any desired temperature below boiling point, and an even and regular
heat is communicated to the air as it is forced through the liquid.

page_text: In order that any condensed water may not pass through the discharge nozzle H,
a bulb K is formed upon the tube near the latter, which serves as a reservoir for such
water, a small glass tube L entering the bulb for a short distance so that the water
cannot flow back.
By the improved apparatus, compressed air saturated with the warm vapour of
the required medicinal decoction is easily and safely supplied to the part to be
treated.
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
The apparatus for the introduction of compressed air into a boiling liquid, so as
to mingle with such air the vapours from the liquid, and to convey the mixture under
pressure to the desired place, substantially as and for the purpose described and shewn
in the drawing.
