COMPLETE SPECIFICATION.
An Improved Inhaler.
We, ARTHUR MATTHEWS PADDON, of Westminster Chambers, 9 Victoria
Street, in the City of Westminster, Associate Member of the Institution of Civil
Engineers, CHRISTIAN EMMANUEL HEDMONDT, of 131 St. Mark's Road, Notting
Hill, in the County of Middlesex, Vocalist, and HENRY LEMPRIÈRE PRINGLE,
of 56 Bartholomew Road, Camden Road, also in the County of Middlesex,
Vocalist, 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 invention has for its object the production of an improved inhaler, more
particularly for the use of vocalists, but which will also be beneficial to others
suffering from hoarseness, &c.
In carrying our invention into effect we use a receptacle of any desired size and
which may consist of a phial either of thin glass, preferably non-transparent, or of
thin metal, in order to allow the contents being affected by the warmth of the hand
of the person using the inhaler. The orifice of the phial should not be less than
one fourth of the maximum transverse sectional area of the phial itself, and it is
preferably closed with a gas-tight ground glass hollow stopper luted with pure
glycerine to keep a tight joint.
The lower portion of the phial is to be filled to the extent of about three-
sevenths to one half of the entire capacity of the phial with manganese dioxide
(MNO2) in a finely subdivided form or fine powder. This is to be hyper-
saturated with the strongest solution of ammonia (NH3) till a small excess is
observable. This excess is to be poured off and the saturated dioxide left in a
solid and level form at the lower part of the phial.
A thin film or diaphragm of cotton wool or other equivalent material is then
spread over its surface. Platinized pumice is then taken in quantity to fill the
remaining space in the phial; this pumice is to be in granular form, preferably
about the size of pearl barley, and it is supersaturated with chloric ether. The
excess of chloric ether having been drained from the pumice, the latter is then
inserted in the phial over the ammoniated manganese dioxide and the phial is to be
filled therewith to the neck. A small plug of cotton wool is then inserted in the
phial to keep grit from the pumice away from the stopper. The phial is then
closed with the stopper.
The volatile ammonia, rising through the pumice, mixes and combines with the
fumes of chloric ether, and the mixed vapors are inhaled by the person using the
inhaler, with the result of removing hoarseness and generally clearing the voice.
For medicinal purposes eucalyptus oil may be substituted for the chloric ether
to an extent not exceeding one fifth of the chloric ether otherwise used; the
proportion of ammoniated manganese dioxide not being in any case reduced.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1. The improved inhaler substantially as herein described.
2. In an inhaler, the combination in a phial, of a lower stratum or body of
ammoniated manganese dioxide and an upper stratum or body of granulated
platinized pumice saturated with chloric ether, substantially as herein described.

granulated platinized pumice saturated with chloric ether and with or without a
proportion of eucalyptus oil, substantially as herein described.
