PROVISIONAL SPECIFICATION.
An Improved Inhaler.
JOHN JOSEPH HARTNETT, M.D. 6 Grosvenor Street, in the County of London,
do hereby declare the nature of this invention to be as follows:-
My invention consists in an improved inhaler which is intended for outdoor use
and is therefore made very portable and of a convenient shape and size for carrying
in the pocket.
The shell of the inhaler is made preferably of a cylindrical form and shaped
somewhat like a small cigar. It is provided with a mouth piece, which when not
in use is covered by a vulcanite or other cap provided for the purpose. The shell
is filled with flannel, cotton wool, or other suitable absorbent material which is
charged with the desired mendicaments, or inhalants, and which serves at the same
time to filter the air which passes therethrough of fog or noxious gases.
I provide for regulating the size of the inlet opening for air so as to vary at
will the quantity of medicated air inhaled. For example I form in the end
plate a curved slot, and I provide a cap or disc for fitting over or on said end
plate, said cap or disc having formed therein two three or more holes. By turning
the cap, one, two, or more of said holes can be brought opposite to the slot, or all
of the holes can be closed.
This little instrument can be carried in the pocket fully charged, and can be
used at any moment, after removing the cap from the mouth piece.

SPECIFICATION.
An Improved Inhaler.
1, JOHN JOSEPH HARTNETT, of 6 Grosvenor Street, in the County of London,
Doctor of Medicine, 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 inhaler. The object of my said invention
is to construct an improved inhaler, that is to say a device for enabling a vapour
or volatile substance to be inhaled. The said device is intended for out-door use
and is therefore made very portable and of a convenient size and shape for carrying
in the pocket.
In order that my said invention may be clearly understood I will now proceed to
describe, by way of example, one construction of the same, with reference to the
accompanying drawings, wherein
Figure 1 is a longitudinal central section of the inhaler,
Figure 2 is a plan thereof; and
Figure 3 is a longitudinal central section of a cap hereinafter referred to, which
is employed to protect the mouthpiece of the inhaler.
Like reference-letters indicate corresponding parts throughout the drawings.
A is the shell of the inhaler, which is of the same size as a small cigar, or there-
abouts. It is filled with flannel, cotton wool, or other suitable absorbent material B,
which is charged with the desired medicaments or inhalants; the material thus

and filters the air, at the same time, of fogs or other noxious constituents.
A' is the mouth piece of the inhaler. A* A³ are screw threads formed upon the
exterior of the shell A...
C is a cap of vulcanite, or of other suitable material, internally screw-threaded to
engage with the screw-threads A' on the shell A, so that the cap can be placed
over the mouth-piece A¹ to protect it, when the apparatus is not in use.
D is a cover which is screwed on to the screw-threaded portion A* of the shell A,
at the opposite end to the mouthpiece. D'D' are perforations in the said cover.
D' is a plate adapted to rotate upon the said cover about a suitable centre-pin or
other retaining device, and provided with holes D³ which are so arranged that by
turning the plate they may be brought into line with the perforations D' in the
cover, as in Figure 1, or may be moved out of line with the said perforations D¹ as
indicated in Figure 2. By suitably adjusting the plate D' to vary the position of
the holes therein relatively to the perforations in the cover, the quantity of

medicated air drawn through the inhaler may be regulated at will.
the plate D to close the perforations D₁ and after putting the cap C over the
mouth piece, the inhaler can be carried in the pocket fully charged ready for use
at any moment, and with its contents preserved from deterioration.
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. A tubular inhaler, charged with medicated material, and provided at one end
with a mouth-piece, and at the other end, with a device for varying the amount of
opening of air passages thereat, substantially as hereinbefore described for the
purposes specified.
2. The tubular inhaler and its appurtenances substantially as hereinbefore described
with reference to the accompanying drawings, for the purposes specified.
