Medicinal or other Matter.
I, JEHANGHIR CAMA, of No. 33 Adolphus Road, Finsbury Park, in the County of
Middlesex, Gentleman, do hereby declare the nature of this Invention to be as
follows:-
This Invention relates to improvements in apparatus for the inhalation or inspiration
of medicinal or other matter.
The apparatus consists of a tube or vessel of metal or other suitable material
having a diminishing neck provided with a screwed or other suitable formed stopper
or capsule.
In the bottom or other convenient part of the tube or vessel is an opening or
aperture which is closed by a valve opening inwards and kept in its seat by means
of a spring or weight.
Between the valve and the neck or outlet of the vessel is placed the material
embodying the substance intended for inhalation-This substance may be in the
form of a disc or washer having a central aperture, or it may be in a spongy or
porous form.
When it is desired to inhale, the stopper is removed and the neck of the apparatus
inserted into the mouth of the user, who after previously emptying the lungs, takes
a fresh inspiration admitting no air except that which is drawn in through the
vessel.
The air passing through the medicated substance, carries along with it particles of
the said substance through frictional contact therewith.
When the medicated matter is exhausted the larger end of the vessel may be
unscrewed, and the disc, washer, or spongy material be renewed.

Improvements in Apparatus for the Inhalation or Inspiration of
Medicinal or other Matter.
1, JEHANGHIR CAMA, of No. 33 Adolphus Road, in the County of Middlesex,
Gentleman 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 :-
This Invention relates to apparatus for the inhalation or inspiration of medicinal or
other matier and will be readily understood on reference to the accompanying
drawings, Figure 1 of which represents an elevation of the apparatus, Figure 2 a
longitudinal section thereof and Figure 3 a detail of a part hereinafter described.
The apparatus consists of a iube A of metal or other suitable material threaded
internally at each end. One end of the tube is closed by a screwed plug B having a
small perforation which is closed by a spring valve which is arranged to open
inwardly.
The other end of the tube A is closed by a screwed plug D which is also provided
with a spring valve d which serves io close the perforation e. Onto the plug D is
serewed the tapering mouthpiece E.
The material which has to be inhaled is enclosed within the tube A between the
plugs B and D and the user places the mouthpiece E in his or her mouth and inhales
as in the case of a person smoking a cigar, the springs C and d allowing air to enter
the tube and pass through the substance in the tube carrying with it particles thereof,
but preventing any passage in the opposite direction or any loss or escape by
evaporation or diffusion. This medicinal substance may be in the form of a disc or
washer having a central aperture or it may be in a spongy or porous form.
The kind of material of which the apparatus is made is of little importance, and the
shape is also subject to variation, but it is proposed to adopt such material and such
designs as will imitate a cigar or cigar holder, or such other smoking utensil as will
permit of its being used publicly without exciting attention or being conspicuous.
Having thus 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 :
1. In an apparatus such as described, the combination of a tube or receptacle A
with plugs B and D and valves C and d substantially as specified.
2. The combination of tube A closed by perforated plugs B D and mouthpiece E
substantially as specified.
Dated this 23rd day of November 1887.
