IMPROVEMENTS IN INHALERS FOR MEDICINAL PURPOSES
Year: 1886

page_text: We, JAMES STURROCK Cashier Bank Street Dundee N.B. GEORGE DUNCAN
MCDOUGALD Chemist, High Street Dundee N.B. do hereby declare the nature
of our invention for IMPROVEMENTS IN INHALERS FOR MEDICINAL PURPOSES to
be as follows:
The object of this invention is to provide an apparatus for the quick and more
convenient production of the vapour of diffusable bodies for the purpose of
inhalation.
This we effect by enclosing in one or more hermetically sealed tubes or capsules
of glass or other suitable material the diffusable bodies and placing them in a
suitable crushing box so that when desired the tubes may be broken and made
to discharge their contents in the box and thus produce vapour to be used for the
purpose of inhalation.
The crushing box may be made in a variety of shapes to suit taste or convenience
as to portability, but it consists essentially of parts brought together by the action
of a screw or other device so as to break the inclosed tubes and retain their
contents for the production of vapour within the apparatus which vapour is
conveyed to the mouth by a tube.
When operating on substances which are diffusable with difficulty a small heater
or steam generator may be attached to the apparatus and the apparatus may
be placed over a vessel containing hot water, in this way moist and hot air will
be supplied which will assist in volatilization.

JAMES STURROCK Cashier, Dundee Advertiser Office Bank Street, Dundee &
GEORGE DUNCAN MACDOUGALD Analytical Chemist, High Street Dundee do
hereby declare the nature of our invention for IMPROVEMENTS IN INHALERS FOR
MEDICINAL PURPOSES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of our invention is an apparatus for the instantaneous production of
the vapour of Diffusible Bodies, for the purpose of inhalation.
Our apparatus for effecting this consists essentially of two parts. First of Tubes
or Capsules of Glass, or other suitable material to contain the diffusible bodies.
Second of a receptacle or box, for holding these tubes made of wood vulcanite, or
other suitable material and provided with a screw, and one or more studs, for the
crushing of the tubes. As a matter of convenience the box may be made to contain
a seperate and detached receptacle for holding the tubes, but this is not absolutely
essential to our invention.
We do not limit ourselves to any relative size or form of parts as these may be
modified considerably without departing from the nature of our invention, but
a convenient form and relative dimensions of parts are shown in our drawings.
Fig. I is a side elevation of our apparatus. Fig. II is a section of same
through A. B, Fig. L A A A is the box. B is the screw which may either form
a handle to the apparatus as shewn in our drawings, or be a short stud and which
is used for crushing the tubes in conjunction with studs C C. DD is a section of
the separate and detached tube holder, which is shown in plan at Fig. 4, with one
tube in position at E. Fig. 3 is a plan of the apparatus. Fig. 5 is a section and
end view of sealed tubes enveloped in bibulous material.
In Figs. I. II & III at F F F is shown a vessel which may be used as a boiler
for the production of steam to assist in the vaporization of difficultly diffusible
bodies, and which is connected with the apparatus by means of a tube made of any
suitable material. In the same figures at G G G is shown the mouth piece through
which the vapours are inhaled. To operate our apparatus the top of the box is
unscrewed at H H Fig. II and one or more tubes are placed in the receptacle. The
top is again screwed on, and the apparatus is ready for use. The tubes are shown
in position at Fig. II I. I.
When it is desired to use the inhaler the handle or stud B is turned. This
causes the receptacle with tubes to rise and the tubes to be pressed against the
studs CC with sufficient force to break the tubes, thus allowing the contents to be
absorbed by the bibulous material in which they were enveloped. On applying
the mouth to mouthpiece and inhaling the air or steam is drawn through the
passages K K K Figs. II & IV and so volatilizes the substances presented to it by
the bibulous material.
In the event of our apparatus being constructed without a separate receptacle,
the tubes are placed in recesses in the box itself and are broken by the screw
handle or stud in a similar way.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and the method of operating the same, we wish it to be distinctly understood
that we do not confine ourselves to the use of two recesses in the tube receptacle
or box, one or any desired number may be used without departing from the nature
of our invention, and what we claim is,
The use of sealed tubes containing diffusible bodies in combination with a
crushing box or apparatus substantially as and for the purposes described.
