Improvements in and relating to Inhalers.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to inhalers.
By an inhaler made according to this invention inhalations may at any moment
be effected, either through the nose or through the mouth, of air charged or not
with various vapours owing to the use of interchangeable vapourizing receptacles.
Besides the distinctive feature that it may be used at will as a buccal or as a
nasal inhaler, my improved device, as compared with the inhalers heretofore
employed, offers the double advantage that the vapourizing receptacles are inter-
changeable, which permits of the use of substances completely differing from each
other, and that the pieces of wad serving to filter the air are isolated from the
material designed for the inhalations, in consequence of which they are less liable
to become moistened and can be immediately renewed if such an accident should
occur.
The improved inhaler comprises a cylindrical receptacle made of metal and
presenting an open extremity and an embossed or depressed extremity; the latter
extends a few millimetres inwards and forms interiorly a cup having a closed
bottom and exteriorly a basin having a bottom pierced with holes. This receptacle
is introduced into a second or outer receptacle made of the same form, although a
little larger, and whose inwardly extending portion fits upon the open extremity
of the first receptacle, while the open extremity of the second receptacle is received
in the cup formed by the inwardly extending part of an exterior sleeve or nasal
extremity of the inhaler.
Into the other extremity of this sleeve is fitted the mouthpiece similar to that of
a cigar holder, differing from the latter only by the larger dimensions of its central
channel in order to allow the inhaled air and vapours to pass more easily, and by a
modification of its interior extremity whose diaineter has been slightly diminished
upon a small length in order to fix thereto various vapourizing receptacles of glass
or of metal.
If the material designed for the inhalations is liquid the first receptacle is filled
up to five-sixths of its height with a porous solid intermediary substance susceptible
of retaining the liquid which will be imbibed, and of giving it off in the form of
vapours to the current of air which traverses this receptacle at the moment of the
inhalation. As intermediary porous substance use is made of pumice stone reduced
to pieces of the thickness of a grain of buckwheat, or other substances capable of
fulfilling the same object as pumice stone.
Owing to their porosity and to the irregularity of their outlines the pieces of
pumice stone represent as many small open reservoirs intercepting empty spaces
which communicate with each other and in which the air circulates more or less
easily.
The imbibition of the intermediary porous substance takes place either by

page_text: instillations, by pouring the volatile liquid drop by drop upon the perforated basin
of the second or outer receptacle after the removal of a cotton plug, or by immersion
of the first or inner receptacle into the same liquid.
If the material intended for the inhalations is solid and in the form of large
pieces, such as camphor, it is introduced directly into the first or inner receptacle
after having been reduced to pieces of the size of a small pea; if it is in the form
of small crystals the sagging of the latter is prevented, so that there may be no
obstacle to the passage of the air, by the interposition of an inert material, which
is also pumice stone reduced to small pieces.
The receptacle thus charged either with solid material giving off vapour or with
intermediary porous bodies which are imbibed by instillations, is put in its place;
then cotton plugs are introduced into the before-mentioned basins, from which they
may be removed with the greatest facility in order to be replaced by dry plugs if
they should have become moist; lastly the mouthpiece is inserted into the open
extremity of the outer sleeve so as to press upon the depressed extremity of the
second or outer receptacle and to keep the whole in place.
When suction takes place through the mouthpiece the air traverses one of the cotton
plugs which filters the same, is charged with vapours as it passes between the pieces
of pumice stone previously imbibed, traverses the second cotton plug which retains
the condensed vapours, and thus arrives at the mouth with the volatile principles
which it carries along.
When it is desired to effect inhalations through the nose the nasal extremity of
the outer sleeve is introduced into both the nostrils or brought near their orifice,
and the air circulates in the opposite direction, the result obtained being however
the same.
In one of the before-described arrangements the vapourizing receptacle of glass
or metal differs from the vapourizing receptacle in the other arrangement by its
bottom, which is simply pierced with holes without extending inwards, by the mode
of imbibition which consists in immersing the receptacle into the volatile liquid of
which it takes up only the quantity retained by the porous material, and lastly by
the mode of closing which is effected, not by an external receptacle, but by
a diaphragm or sieve of wire gauze let into the receptacle so as to provide an
empty space for receiving the second cotton plug and the extremity of the mouth-
piece. The first cotton plug is introduced through the orifice of the nasal extremity
into the depressed part of the outer sleeve.
When the material adapted for the inhalations is viscous, like tar for instance,
use is made of a receptacle carried by the mouth-piece. It is formed of a metallic
tube whose depressed extremity and lateral walls are closed and lined with a bag upon
a portion of its height; these lateral walls are pierced with holes within a zone
comprised between the preceding segment and the section of the open extremity
of the receptacle which receives the mouthpiece, the second cotton plug and the
diaphragm or sieve of wire gauze. The air drawn is charged with vapours emitted
by the viscous substance and arrives in the mouth after having traversed the lateral
holes in the aforesaid receptacle.
This improved pocket inhaler is placed in its metallic case; by removing the
cover from this case the nasal extremity of the depressed sleeve may be introduced
into the nostrils, or simply brought close to the latter, to effect inhalations through
the nose without attracting attention, the device being concealed in the palm of the
hand. This arrangement enables the pocket inhaler to be used as a smelling
bottle.

1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 pocket inhalers.
By an inhaler made according to this invention inhalations may at any moment.
be effected, either through the nose or through the mouth, of air charged or
not with various vapours owing to the use of interchangeable vaporizing
receptacles.
In order that my invention may be properly understood I have represented it in
the accompanying drawing in which
Figure 1 shows an exterior view of my inhalers.
Figure 2 is a longitudinal section, showing a mouthpiece pressing upon a
complete vapourizing receptacle.
Figure 3 is a section through my inhaler, showing the monthpiece which carries
a simple vapourizing receptacle.
Figure 4 represents a section through a special receptacle for viscous materials,
carried by the mouthpiece like the receptacle shown in Figure 3.
Figure 5 represents the pocket inhaler placed in a metallic case in such a
manner that its nasal extremity projects on the removal of the cover from the
case.
Besides the distinctive feature that it may be used at will as a buccal or as a
nasal inhaler, my improved device, as compared with the inhalers heretofore
employed, offers the double advantage that the vaporizing receptacles are inter-
changeable, which permits of the use of substances completely differing from each
other, and that the pieces of wad serving to filter the air are isolated from the
material designed for the inhalations, in consequence of which they are less liable
to become moistened and can be immediately renewed if such an accident should
occur.
The inhaler shown in Figures 1 and 2 comprises a cylindrical receptacle V made
of metal and presenting an open extremity and an embossed or depressed extremity:
the latter extends a few millimetres inwards and forms interiorly a cup having a
closed bottom and exteriorly a basin having a bottom pierced with holes. This
receptacle V is introduced into a second or outer receptacle R made of the same
form, although a little larger, and whose inwardly extending portion fits upon the
open extremity of the first or inner receptacle V, while the open extremity of the
second or outer receptacle R is received in the cup formed by the inwardly
extending part of an outer sleeve E or nasal extremity of the inhaler.
Into the other extremity of this sleeve E is fitted the mouthpiece B similar to
that of a cigar holder, differing from the latter only by the larger dimensions of its
central channel in order to allow the inhaled air and vapours to pass more easily,
and by a modification of its interior extremity whose diameter has been slightly
diminished upon a small length in order to fix thereto various vaporizing receptacles
of glass or of metal like those shown in Figures 3 and 4.
If the material designed for the inhalations is liquid the receptacle V, Figure 2,
is filled up to five-sixths of its beight with a porous solid intermediary substance
susceptible of retaining the liquid which will be imbibed, and of giving it off in
the form of vapours to the current of air which traverses this receptacle at the
moment of the inhalation. As intermediary porous substance I use pumice stone

page_text: reduced to pieces of the thickness of a grain of buckwheat, or other substances
capable of fulfilling the same object as pumice stone such as porcelain wood or
the like.
Owing to their porosity and to the irregularity of their outlines the pieces of
pumice stone represent as many small open reservoirs intercepting empty spaces
which communicate with each other and in which the air circulates more or less
easily.
The soaking of the intermediary porous substance takes place either by
instillations by pouring the volatile liquid drop by drop upon the perforated basin
of the second or outer receptacle R, Figure 2, after the removal of the cotton
plug T, or by immersion of the receptacle V1, Figure 3, into the same liquid.
If the material intended for the inhalations is solid and in the form of large
pieces, such as camphor, it is introduced directly into the receptacle V, Figure 2,
after having been reduced to pieces of the size of a small pea; if it is in the form
of small crystals the sagging of the latter is prevented so that there may be no
obstacle to the passage of the air, by the interposition of an inert material, which
is also pumice stone reduced to small pieces.
The receptacle V thus charged either with solid material giving off vapour or
with intermediary porous bodies which are soaked by instillations, is put in its place,
as shown in Figure 2; then the cotton plugs T and T₁ are introduced into the
before-mentioned basins, from which they may be removed with the greatest
facility in order to be replaced by dry plugs if they should have become moist; lastly
the mouthpiece B is inserted into the open extremity of the outer sleeve E so as to
press upon the depressed extremity of the second or outer receptacle R and to keep
the whole in place.
When suction takes place through the mouthpiece B the air traverses the
cotton plug T which filters the same, is charged with vapours as its passes between
the pieces of pumice stone previously soaked, traverses the cotton plug which
retains the condensed vapours, and thus arrives at the mouth with the volatile
principles which it carries along.
When it is desired to effect inhalations through the nose I introduce the nasal
extremity of the outer sleeve E into one or the other nostril or bring it near their
orifice, so that the air will circulate in the opposite direction, the result obtained
being however the same.
or
The vaporizing receptacle V₁ shown in Figure 3 which may be made of glass
metal, differs from the vaporizing receptacle V represented in Figure 2 by its
bottom, which is simply pierced with holes without extending inwards, by the
mode of imbibition which consists in immersing the receptacle into the volatile
liquid of which it takes up only the quantity retained by the porous material, and
lastly by the mode of closing which is effected, not by an external receptacle, but
by a diaphragm or sieve C of wire gauze let into the receptacle so as to provide
an empty space for receiving the cotton plug T' and the extremity of the mouth-
piece. The cotton plug T is introduced through the orifice of the nasal extremity
into the depressed part of the outer sleeve E.
ย
When the material adapted for the inhalations is viscous, like tar for instance,
use is made of a receptacle V", Figure 4, carried by the mouthpiece, like the
receptacle V, Figure 3. It is formed of a metallic tube whose depressed extremity
and lateral walls are closed and lined with a bag S upon a portion of its height;
these lateral walls are pierced with holes within a zone comprised between the
preceding segment and the section of the open extremity of the receptacle which
receives the mouthpiece B the cotton plug and the diaphragm or sieve C of
wire gauze. The air drawn is charged with vapours emitted by the viscous
substance and arrives in the mouth after having traversed the lateral holes in the
receptacle V".
Figure 5. represents the pocket inhaler placed in its metallic case M; by
removing the cover M' from this case the nasal extremity of the depressed
sleeve E may be introduced into the nostrils, or simply brought close to the latter

page_text: to effect inhalations through the nose without attracting attention, the device being
concealed in the palin of the hand. This arrangement also enables the pocket
inhaler to be used as a smelling bottle.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
First. A pocket inhaler made of two metallic tubes V and R depresse or
embossed to the shape of a re-entering basin and having a perforated bottom at
one of their extremities, one being fitted in the other so as to form a receptacle,
the perforated basins serving to receive cotton plugs and the whole being covered
by a sleeve E depressed or embossed at one extremity to form a nasal adjutage
and receiving at its other end a mouthpiece B.
Second. An inhaler comprising a sleeve E provided with a mouthpiece B and
containing a receptacle V having a perforated bottom which is closed by a
removable diaphragm or sieve C of wire gauze.
Third. In an inhaler the employment of a receptacle V covered by a sack in
order to be soaked with viscous medicaments, and provided with lateral holes for
the passage of air.
Fourth. In an inhaler the employment of pieces of porous materials, such as
pumice stone, porcelain, pieces of wood or the like, that is to say of various
absorbent materials in irregular pieces which allow the air to pass between
them.
Fifth. The improved pocket inhaler in combination with a case M. which permits
it to be used as a smelling bottle in order to effect secret nasal inhalations without
showing the device, the latter being enclosed in a case and adapted to be concealed.
