COMPLETE SPECIFICATION.
An Improved Dry Air Inhaler and Injector to Enable the Inhalation
and Injection of Atmospheric Air and Gases Heated to High
Temperatures by Human Beings and Animals.
I LEWIS ABRAHAM TALLERMAN of The Langham Hotel Portland Place
London W. 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 :-
The object of this my invention is to provide an apparatus by means of which
may be inhaled or injected into the human or animal body at temperatures raised
or lowered at will dry atmospheric air, compressed air & gases, whether
medicated or non-medicated saturated or comingled with other gases or respirable
substances under pressure or otherwise also fumes or smoke arising from the
combustion of mineral & vegetable matter.
And wherewith the temperature of the said air and gases may be goverened &
regulated so that it may be maintained or gradually or quickly raised or lowered
or varied at will during the time that the process of inhaling or injecting is being
carried out & by the said gradual raising of the temperature to enable the use
of the beforementioned iuhalants & injections without risk or danger to the
patient.
Also to enable any moisture introduced respired into or through any cause
whatever present in the apparatus to be evaporated or otherwise expelled before
or during the time the process of inhaling or injecting is being carried out thereby
drying the said air gases or other contents of the apparatus.
Also to enable the disinfection of the said air gases or other inhalants and
injections by subjecting them to the action of extreme heat.
I construct my apparatus in the following manner, riz.,- construct a copper
receiver A of convenient form and size preferably cylindrical and of about
28 inches in length and 16 inches in diameter to hold the air gas or other
inhalant or injection to be used. This receiver may be bell-shaped oval or other
convenient shape and its dimensions larger or smaller. I do not confine myself to
the use of copper any other suitable metal or material may be used in the con-
struction of both the receiver and the fittings of the apparatus and the forms,
and proportions of both may be varied.
B
One end of the receiver if cylindrical is closed by an air-tight metal cap
having a projecting metal tongue at the bottom thereof which tongue passes
through a loop projecting from the bottom of the receiver and serves as a pivot on
which the said cap called the valve-cap can move when open. When closed it is
fastened to a lug on the top of the receiver by a fast running screw C.
At the top or side but preferably at the opposite end fastened to the receiver
preferably by a tourniquet is a tube or funnel or trumpet shaped fitting D
projecting outwards and upwards of metal or other suitable material divided into
three sections called the inhaling chambers.
The centre section is formed by two screens of wire net E placed midway in
the said fitting and three inches apart, it has a door or slide and forms the
chamber F in which the dry air gases and other inhalants and injections in
passing through may be medicated or saturated and in which vapourization or
volatilization inay be carried out.

page_text: Volatilization and evaporation or vapourization of medicaments and other
substances for inhalation or injection may also be carried out in the receiver which
presents greater facilities for quickening both processes by reason of the greater
cubic contents thereof permitting the exposure of a greater medicated surface to
the action of greater and more direct dry heat and also by reason of the superior
outlets G. H. I. for ventilation and regulating the temperature by continuous or
intermittent currents according as the said outlets may be opened or closed.
At the top of the inner inhaling chamber riz., that section next to the receiver is
a metal outlet tube G about 2 inches high having an outlet one inch in diameter
which closed with a metal stopper or key this when opened in conjunction with a
similar tube on the bottom H of the receiver induces a continuous current for the
purpose of ventilation evaporation and the replacement of air removed from the
receiver during the process of inhaling and injection and a freer circulation of
bented dry air from the receiver to the inbaling chambers is promoted.
Two panels J one on each side of the receiver act as ventilators when required
and close by slides or doors.
The outer inhaling chamber K has a thermometer L the bulb of which passes
into the interior the scale showing on top indicates the temperature therein.
When the apparatus is used as an inhaler an ordinary oral nasal or ora-nasal
piece M or tube or cannula or other fitting suitable or convenient for the purpose
is connected with the outer end of the inhaling chambers and the air or gas may be
compressed when required by use of the pumping gear described hereafter for the
purpose of injecting. A pressure gage N at the top of the receiver indicates the
pressure within.
The receiver may be heated by gas O oil spirit or electricity, preferably by
gas applied to the bottom thereof and the inside temperature is indicated by a
thermometer P as in the inhaling chambers before described.
To raise the temperature the valve-cap B and outlet tubes are closed and the
gas is turned full on until the required temperature is registered. To lower the
temperature the reverse of the foregoing operation is carried out, viz.,-the outlets
are partly or entirely opened as also the valve-cap and the gas turned down.
If it be desired to maintain a certain temperature attention must be paid to
the manipulation of the valve-cap and the opening and closing of the before
mentioned outlets will be regulated in accordance with the movements registered
by the thermometer.
When the apparatus is used as an injector for the valve-cap used for the
inhaler is substituted a similar air tight copper cap Q having a small copper
cylinder R open at both ends fitted in the centre on the inner side thereof so
that when closed the small cylinder is in the interior of the receiver and projected
towards the centre. A brass piston rod S of about three-quarters of an inch in
diameter passes from the outside through the centre of the cap into the small
cylinder and at the end of the piston rod so passed through a disc of wood T
or other suitable material is fixed.
The rod is then pushed forward thereby forcing the air out of the small cylinder
into the receiver and consequently forcing almost as much heated air as was
displaced from the cylinder through the funnel. The piston rod is then drawn
back and the vacuum caused by this pumping operation is filled by air admitted
from the outside into the receiver through one of the outlet tubes which admitted
air is at once heated by mixing with a large volume of hot air.
I do not confine myself to this pumping gear but may substitute for it any
suitable ordinary pumping gear worked by a lever from the outside.
To the outlet at the end of the inhaling chambers is fitted a tube pipe cannula.
rose or other fitting suitable for the purpose of injecting hot dry air and gases
medicated or non-medicated smoke and fumes the results of combustion volatilization
or evaporation.
When used as an inhaler the patient is seated or lying and inspires through
the oral or nasal or cra-nasal piece at the end of the outer inhaling chamber

page_text: at a temperature commencing at 100 degs. Fah. which is gradually raised in the
manner before described. When used as an injector the injection is forced
through the mouth nose or anus or any artificial opening or aperture natural or
artificial by the pumping operation before described and the temperature is raised
and regulated in a similar manner.
Volatilization vapourization and evaporation is effected by the exposure of
medicaments and other substances in vessels trays or saturated fabrics or other
material placed in the inhaling chambers or hung on frames or otherwise con-
veniently placed in the receiver.
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
1. A dry hot air inhaler and injector for human beings and animals the system
of heating and ventilating which, enables moisture introduced by respiration or
otherwise to be evaporated therefrom before and during the process of inhaling or
injecting substantially as herein before described.
2. A hot dry air inhaler and injector by means of which atmospheric air
compressed air and gases medicated or non-medicated may be gradually heated
to any required temperature and maintained thereat for any desired time or the
temperature may be raised and lowered and regulated at will during the process
of inhaling and injecting thereby enabling the use of the highest degree of heat
that can be borne by each patient to be ascertained and used without risk or
danger substantially as herein before described.
3. An inhaler and injector in which is volatilized or evaporated or vapourized
by dry heat medicaments and other substances wherewith to charge or saturate the
atmospheric air gas or other inhalant or injection to be used the degree of heat
being regulated at will and raised or lowered or maintained at the temperature
most suitable for quickening or retarding the process of volatilization and
vapourization before and during the process of inhalation and injection sub-
stantially as hereinbefore described.
