I CORNELIUS BENNETT HARNESS of 21 Holborn Viaduct in the City of London,
Electrician do hereby declare the nature of my Invention for IMPROVED

as follows:-

>
My Invention relates to an improved apparatus for facilitating the inhalation
of medicated vapour and is especially designed to provide improved means whereby,
the person using the apparatus will be able to regulate the supply of air to the
same in a very convenient and simple manner.
In carrying the said Invention into practice I provide a tube which may be of
block tin or other metal or material, a mouth-piece being provided therein midway
between the two ends. Each end of the tube is furnished with an internal screw-
thread designed to receive an externally screw-threaded piece secured to one end
of a wooden or other handle in such a manner that these handles may be screwed
to the tube or unscrewed therefrom at will. Each of these handles is tubular
and a rod extends through the same from end to end. The said rod also extends
through the externally screw-threaded piece and carries at this end a stud or disc
provided on its inner face with a washer of leather, india rubber or other suitable
material which is kept tightly pressed against the orifice by tlie action of a spiral
spring provided within each of the handles, the orifice being thus made air-tight.,
The other end of each rod is 'cohnécted with a stud or push piece projecting"
outside the other end of the handle in such a manner that by pressing upon
the same the person using the instrument can push the rods inward against the
action of the springs and so uncover the orifice of the externally screw-threaded
piece, this operation having the effect of allowing atmospheric air to enter the.
tube through this orifice, a small aperture in the periphery of the handle allowing
the outer air to enter the latter.
·
The material or compound whose vapour is to be inhaled is placed within the
central tube (which preferably contains sponge or similar substance for absorbing
the same) then the two handles are screwed tightly to the ends, access of the
outer air being prevented by the leather or other washers held in place by the
spiral springs as above explained. The person desiring to use the apparatus grasps
the two handles and pressing the two studs or push pieces at their ends thus
admits the cuter air and can then conveniently inhale the vapour by applying
his mouth to the mouth piece.

page_text: I, CORNELIUS BENNETT HARNESS, of 21 Holborn Viaduct, in the City of
London, Electrician do hereby declare the nature of my Invention for "IMPROVED
APPARATUS FOR FACILITATING THE INHALATION OF MEDICATED VAPOUR" and in
what manner the same is performed, to be particularly described and ascertained
in and by the following statement:-
My Invention relates to an improved apparatus for facilitating the inhalation
of medicated vapour, and its chief object is to provide means for enabling the
person using the apparatus to regulate or control the supply or admission of air
to the same in a very convenient, simple, and efficient manner.
My improved apparatus is illustrated in the accompanying Drawing, which
shows the same partly in elevation and partly in longitudinal central section.
a is a tube, which may be of block tin or other suitable metal or material, and
which is provided with a mouth-piece b midway between its ends. .A ferrule or
ring c, having an internal screw-thread, is soldered, or otherwise fixed, in each end
of the tube a. d. d are handles, of wood or other suitable material, each provided
with an externally screw-threaded piece e which fits into one of the rings or
ferrules c, so that the said handles' may be screwed to the tube or unscrewed
therefrom at will. Through each of the handles d is passed a rod f, one end of
which extends through the piece e and carries a plate or disc f¹. This plate or
disc is provided on its inner face with a washer g of leather, india-rubber or other
suitable material, so as to form a valve capable of closing the orifice or passage e¹
in the piece e. A spiral spring is placed upon each of the rods f so that it bears
at one end upon the end of a recess or cavity d¹ in the handle, and at the other
end upon a cap or. push-piece f2 fixed on the outer end of the said rod. This
spring tends to press the washer g against the end of the piece e and thus close the
orifice or passage e', thereby preventing the admission of air to the tube a through
the said orifice. The opening of the said valve is effected by pressing upon the
cap or push-piece f² and thereby forcing the rod f inward against the action of the
spring h.
A small aperture i is formed in each of the handles & for the admission of air to
the tube a when the said valve is opened.
The mouth-piece b has a perforated screw-cap b¹. This cap is made somewhat
larger in diameter than the other part of the said mouth-piece so that the latter
can be easily retained in the mouth; but the said mouth-piece may, if desired, be
made in any other suitable manner.
By providing the ends of the tube a with the ferrules or rings c, I ensure the
tightness of the joints between the said tube and the handles by forming a wider
surface for the said joints than would otherwise exist. I prefer to insert a ring
or washer of elastic material between the ends of the tube a and the handles d.
In preparing my improved apparatus for use, one of the handles d is removed
from the tube a, and the substance or compound, the vapour of which is to be
inhaled, is placed within the said tube (which is preferably filled with sponge,
cotton wick or other absorbent material); the said handle is then screwed tightly
to the end of the tube and the apparatus is ready for use, the said tube being kept
air-tight by the pressure of the valves upon their seats. The person desiring to
use the apparatus grasps. the two handles d and applies his mouth to the mouth-
piece b, then, by pressing one or both of the caps or push-pieces f³,
he opens
the
orifice or orifices e¹ for the admission of air to the tube a; he can then conveniently

page_text: inhale the
vapour of the substance contained in the tube and at the same time
regulate or control the supply or admission of air to the said tube by pressing
more or less upon the said caps or push-pieces.
I do not confine myself to the particular form of construction shown in the
Drawing, as it is obvious that the same may be somewhat modified, for example,
the rods for operating the valves are, in some cases, bent and arranged to project
through the handles on one side thereof, where they are provided with suitable
means for operating them.
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 above described improved apparatus having the handles screwed into the
tube and provided with valves and means for operating the same, substantially as,
and for the purpose, set forth.
