page_text: We, FREDERICK WILLIAM LOXTON, Surgeon's Assistant, and AUGUSTIN MCSWINEY,
Engineer, late of 147 Queen Victoria Street, in the City of London, but now of 139
Hanbury Street, in the County of Middlesex, do hereby declare the nature of our said
invention 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 to manufacture a compact, cheap, efficient and
convenient inhaler, capable of being carried in the pocket at all times, and ready for
immediate use.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of our invention; Fig. 2 is a sectional elevation on the line ab.
Fig. 3 is a top view, and Fig. 4 is a separate elevation of the movable glass neck and
mouth piece.
c is a cylinder or tube formed of metal or other suitable substance. is a per-
e is another diaphragm of perforated metal,
manent diaphragm of perforated metal.
which rests upon a narrow ring of metal, soldered to the cylinder; or such ring or
ledge may be formed in the cylinder itself by spinning. The diaphragm e is movable,
and is retained in position by the mouthpiece f, forined of glass, or other suitable
substance.
The space g, between the two diaphragms, is filled with saw-dust, or other small
cubes or granules of wood of an absorbent nature, which receives, absorbs, and retains
the drugs, or other medical substances or materials, that may be prescribed by the
Physician for inhalation.
When using the inhaler, the external air ascends through the lower diaphragm, and
passes upwards through the interstices among the particles of wood, the air becoming
thereby impregnated with the vapour arising from the absorbed drugs and other
substances, and such medicated air passes inwards through the upper diaphragm e,
and through the mouthpiece for the usual purposes of inhalation.
Our improved inhaler is readily recharged, when exhausted, by pouring the
medicinal substances on the top of the fixed diaphragm and can be emptied by simply
removing the mouthpiece and diaphragm e, and refilling, as above described.
In this specification the word "cylinder" is intended to include other sectional
forms, such as square, hexagonal, elliptical, or other forms; the diaphragms and
mouthpiece being modified accordingly.
:-
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
1. The manufacture and use of inhalers consisting of a cylinder c, fitted with

page_text: perforated diaphragms d and e, and mouth-piece f, substantially as herein before
described and shewn on the drawings.
2. In combination with inhalers the application and use of saw-dust or granulated
wood, for absorbing drugs and medicinal preparations, substantially as and for the
purposes herein before described.
3. The general, combination, arrangement, and construction of the several and
respective parts, together forming our invention of an inhaler, substantially as herein
before described and shewn on the drawings.
