Improvements in Inhalers.
I SIDNEY JORWERTH MANSEL-HOWE of Londesborough House Godstone in the
County of Surrey Physician do hereby declare the nature of this invention to be as
follows
:-
This invention relates to improvements in inhalers and it is designed for medical
purposes more especially for the inhalation of vapours arising from volatile medica-
ments when it is necessary to inhale vapour resulting from the chemical union of
two simple vapours.
My improved inhaler is especially adapted for use where it is desirable that such
chemical union should take place between vapours arising from 'two medicaments
having chemical affinity the one for the other but is capable also of being used
where the vapours from two medicaments have no chemical affinity the one for the
other of them.
My improved inhaler consists of a vessel which has two chambers one for the
reception of one of the medicaments, and the other for the reception of the other
medicament intercommunicating by one or more hole or holes in the partition
between them, and arranged in such a way that on inhalation the vapour proceeding
from one chamber must pass thro' the medicament or substance unpregnated with
the medicament in the other chamber.
Preferably I form my improved inhaler as follows, one of the chambers of the
vessel is superimposed on the other and they are divided by a perforated diaphragm
at the point of division between the chambers. The vessel is constructed to form
a neck so that the body of the vessel presents an hour glass, dumb-bell or double
bell appearance, and it may be formed of glass, porcelaine, or other suitable material
and is open at its upper and lower ends.
The top of said vessel is provided with a removable cover in the shape of a
dome. A tube leading from the upper portion of said dome to form a conduit
through which the vapour or vapours is or are inhaled.
Into the lower end of said vessel is fitted a perforated base having suitable studs
or feet upon the under side thereof to afford free access of air into the body of
said vessel.
The medicaments are preferably placed in the two chambers of the said vessel in
the manner following, the medicament which is most readily volatilized being
placed in the lower chamber, and the other of said medicaments in the upper
chamber. Pummice sponge or other porous material may be inserted in the chambers
when the medicament employed is in a liquid form.
Upon applying suction to the open end of the before mentioned tube, vapour
arising from the medicament in the lower chamber passes by any of the perforations
in the diaphragm through the medicament in the upper chamber and in this way
chemical union of the two vapours better produced.

Improvements in Inhalers.
I SIDNEY JORWERTH MANSEL-HOWE of Londesborough House Godstone in
the County of Surrey, Physician 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 improvements in inhalers and it is designed for medical
purposes more especially for the inhalation of vapours or volatile principles arising
from medicaments when it is necessary to inhale a vapour or a volatile principle
resulting from the chemical union of two distinct substances.
My improved inhaler is especially adapted for use where it is desirable that such
chemical union should take place between volatile principles arising from two
medicaments having chemical affinity the one for the other, but it is capable also of
being used where the vapours from two medicaments have no such chemical affinity
the one for the other.
My improved inhaler consists of a vessel which has two adjacent chambers one
for the reception of one medicament and the other for the reception of the other
medicament, such chambers intercommunicating by one or more hole or holes in
a partition between them, and the said vessel being arranged in such a way that on
inhalation the vapour or volatile principle contained within the chamber further
removed from the mouthpiece must of necessity pass through the chamber
containing the medicament or substance unpregnated with the medicament in the
other chamber.
In the accompanying drawing I have illustrated the form of the inhaler which
I preferably adopt. As will be seen one of the said chambers A is superimposed
on the other chamber B and they are divided by a perforated diaphragm C at the
line of separation between the chambers.
The vessel X is constructed in its central portion to form a neck N so that the
body of the vessel presents an hour-glass, dumb bell or double bell appearance,
and it may be formed of glass, porcelain, or other suitable material, and is open
at its upper and lower ends. The top of the vessel X is provided with a removable
cover D in the shape of a dome. A tube E leading from the upper portion of the
said dome to form a conduit through which the vapour or vapours is or are inhaled.
Into the lower end of the said vessel X is fitted a perforated base F having suitable
studs or feet G upon the under side thereof to afford free updraught or inspiration
into the chambers of the vessel X and being attached thereto by suitable joints.
The medicaments are placed in the two chambers A and B of the vessel X in
the following manner-the medicament which is the more readily volatilized being
placed in the lower chamber B and the other of the said medicaments in the upper
chamber A. When the medicament or medicaments is or are in a liquid form,
pummice, sponge, or other porous material may be inserted in the respective
chambers.
Upon applying suction to the open end of the before mentioned tube E, air is
drawn in through the apertures or perforations in the base F into the chamber B
and carries the volatile principles of the medicament in that chamber, through the
perforations in the diaphragm C into the chamber A. When chemical affinity
exists between the medicaments in the chambers A and B, these unite in chemical
union, the vapour of the newly formed compound being inhaled through the mouth-
piece E.
When however no such chemical affinity exists the volatile principles
contained in chambers A and B intermingle only and are inhaled through the
mouthpiece E in this way.
In this invention as described and illustrated it will be found that such medica-
ments are brought into immediate contact with each other and most favourably tend
to promote chemical union between them when chemical affinity exists.

page_text: 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,
An inhaler consisting of a vessel which has two adjacent chambers, one for the
reception of one medicament and the other for the reception of another medicament,
such chambers intercommunicating by one or more hole or holes in a partition
between them and such vessel being arranged in such a way that on inhalation the
vapour proceedling from the more volatile medicament contained in the chamber
nearer the inlet of air (perforations in the base F on plan) must pass through the
second chamber containing the second medicament.
