PROVISIONAL SPECIFICATION.
An Improved Method of and Appliance for Administering Medicines
and Stimulants by Inhalation.
I, DANIEL NICHOLS, of 48 Shakespeare Street, Manchester, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows: :-
My invention relates to an improved method of and appliance for administering
medicines and stimulants by inhalation.
The ordinary mode of inhaling is to inspire through a mouthpiece or tube the
vapour arising from a hot liquid contained in a vessel to which air is admitted
through another tube. This mode if the liquid be highly heated produces n
scalding sensation in the throat because the steam or vapour inhaled is not
sufficiently moist.
The improved method consists in drawing the atmosphere to be inhaled through
a liquid such as a drug or wine or spirit which is preferably heated by dilution
with boiling water whereby the indrawn air becomes more or less saturated before
inhalation.
The improved appliance which I prefer to employ for the purpose above named
consists of a glass or other suitable vessel with a mouthpiece or tube the
inner end of which is at or near the top of the bottle and above the liquid
contents.
The inner end of another tube by which air is admitted to the vessel is below the
surface of the liquid and preferably close to the bottom while the outer portion of
the tube is curved or carried off some distance so that it is impossible for the
person using the inhaler to breathe upon the end of the inlet tube and re-inhale
the air expired from the lungs.
By the use of my improved appliance stimulants may be administered without
passing through the stomach of the invalid and doctors or others attending cases of
infectious diseases may be protected from infection by inhaling air passed through
a disinfecting liquid.
Dated this 4th day of November 1891.

COMPLETE SPECIFICATION.
An Improved Method of and Appliance for Administering Medicines
and Stimulants by Inhalation.
I, DANIEL NICHOLS, of 48 Shakespeare Street, Manchester, in the County of
Lancaster, Engineer, 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 :-
My invention relates to an improved method of and appliance for administering
medicines and stimulants by inhalation.
The ordinary mode of inhaling is to inspire through a mouthpiece or tube the
vapour arising from a hot liquid contained in a vessel to which air is admitted
through another tube. This mode if the liquid be highly heated produces a
scalding sensation in the throat because the steam or vapour inhaled is not
sufficiently moist.
The improved method consists in drawing the atmosphere to be inhaled through
037

page_text: a liquid such as a drug or wine or spirit which is preferably heated by dilution
with boiling water whereby the indrawn air becomes more or less saturated before
inhalation.
The improved appliance which I prefer to employ for the purpose above named
consists of a glass or other suitable vessel with a mouthpiece or tube the inner
end of which is at or near the top of the bottle and above the liquid contents.
The inner end of another tube by which air is admitted to the vessel is below
the surface of the liquid and preferably close to the bottom while the outer portion
of the tube is curved or carried off some distance so that it is impossible for the
person using the inhaler to breathe upon the end of the inlet tube and re-inhale the
air expired from the lungs.
In the accompanying drawing I show a convenient form of my improved
inspirator or inhaling appliance in which a is the glass vessel, 6 the mouthpiece the
inner end of which is near the top of the vessel a, ce are two cork or other suitable
washers for making an airtight joint between the vessel a and tube b, d is the other
tube by which air is admitted to the vessel the inner end of this tube being below
the surface of the hot liquid and reaching nearly to the bottom of the vessel, e is a
cork or other washer for making an airtight joint between the vessel and the
tube d.
The person using the inhaler applies his mouth to the tube band by inspiring
draws air through the tube d and through the hot liquid in the vessel a the air thus
becoming more or less saturated and reaching the mouth and throat of the patient
in a heated and moistened condition.
By the use of my improved appliance stimulants may be administered without
passing through the stomach of the invalid and doctors or others attending cases
of infectious diseases may be protected from infection by inhaling air passed through
a disinfecting liquid.
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. The improved method of administering medicines and stimulants by drawing
the atmosphere to be inhaled through a liquid preferably hot whereby the indrawn
air becomes heated and more or less saturated before it reaches the mouth of the
patient substantially as herein specified.
2. The improved inspirator or inhaling appliance the chief feature of novelty in
which consists in placing the end of the air inlet tube below the surface of the
liquid in the vessel so that all the indrawn air has to pass through and is heated and
moistened by the liquid substantially as herein set forth.
