An Improved Apparatus for the Inhalation of Condensed Air and
the Exhalation into Rarefied Air for Curing Diseases of the
Respiratory Organs and Air Tubes of the Human Body.
I, JOHN PITT BAYLY, of 18 Fulham Place, Paddington, in the County of
London, Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, (a communication to me from abroad by
August Gübel, of Bad Ems, Prussia, in the German Empire, Engineer,) to be
5 particularly described and ascertained in and by the following statement :-
My invention relates to an apparatus for the inhalation of condensed air in every
conceivable manner and the exhalation into rarefied air, for curing diseases of the
respiratory organs and the air tubes of the human body, in a manner shown by the
accompanying sketches and description.
DESCRIPTION OF THE DRAWINGS.
The contrivance which is represented on the Sheet I, in total and on the
Sheets I and II, in its several chief parts consists of two separate systems, a) for
the production and the inhalation of condensed air, 6) for the rarefaction of the air
and the exhalation into the same, which act quite independently of each other, the
effect of which however can be combined for the patients.
On account of their great length they are represented in two parts on Sheet I, of
which it must be understood that the lower part of the left margin belongs to the
right margin of the upper part. There are then found on the left all the machines
and apparatuses for the condensed air, on the right all the machines and apparatuses
for the rarefied air. The motive power and the pneumatic pumps are exactly of
the same construction for both purposes. The machine A inhales the air out of the
open air by means of the tube a, the air having to run through the expansion which
is filled with wadding in order to leave behind particles of dust. It is condensed
and pressed under the regulators C and C', where it receives a pressure corresponding
to the pressure of the weights. In order to make it possible that the same pump A
delivers air of different pressure to the regulators C and C', there is inserted
between the latter a regulating valve. Instead of two regulators, three and more
can be put in operation to receive air of any degree of compression. From the
regulators C and C", the air passes through the warming apparatuses E, and E', and
enters into the tubes g, and ', which now contains condensed and warmed air of
lifferent pressure. The machine B lifts the air from the regulators D and D'
communicating by means of a tube supplied with a regulating valve r, in the same
nanner as in C and C, and leads it into the open air. The tubes and ¹, are
connected with these regulators and consequently contain air rarified to different
legrees. Instead of two regulators there may be three or more in order to obtain
arified air of various degrees.
Machine M compresses a smaller quantity of air to a higher degree than
achine A and forces it into the reservoir W which is provided with a manometer
nd a regulating safety valve, and from which it goes into the tube m.
The machines A and B, with the regulators C and D, are represented on the
heet II.
A square basis supports two vessels G, G', enlarged at the top in form of a wreath
ontaining two moveable cylinders K and K', which are closed at the top, but open
the bottom. They are sufficiently heavy to produce a pressure of a water column
40 cm. they are suspended to a wire which goes over the roll H. Beneath
ery cylinder there are two pipes, one with a suction valve, the other with a
rcing valve. The suction tubes stand on a common pipe which leads to the open

page_text: air and which has an expansion filled with chemically purified wadding through
which the air drawn up must pass.
The forcing tubes also stand on a common pipe which leads the compressed air
into the regulators C and C. The disk H is fastened to an axle tree, which resting
on two supports can turn round on its axis and carries a cog wheel in front. This
motion causes alternately one of the cylinders K K to rise, whilst the other is
pressed down by its own weight. When the vessels G G¹ are filled with water, the
air enters as soon as the cylinders go up. On their coming down the air is
condensed and forced into the regulators C and C'. The compression it receives
depends on the weight that bears on the cylinders of the regulators C, C, and
through the heating apparatuses E, E', it receives a temperature to render it fit for
respiration through the mouth and passes then through the tubes g, g' to be
inhaled.
The piston P of the machine is put in motion by the pressure of the high water
service.
The regulator C for the condensed air consists of a vessel i, which is open at the
top, and in which a cylinder k can go up and down along a bar which regulates its
movements; beneath it are two tubes, one to admit the air, the other to carry it
away. When the vessel i contains water, the air introduced beneath the cylinder k
cannot escape and tries to lift the latter and receives a compression proportionate
to the weight which bears on this cylinder. A manometer with coloured water
indicates the pressure. To prevent the cylinder k from being lifted out of the water,
it is provided with a valve which at a certain height opens itself to let any further
supply of air escape.
The regulator D for the rarified air consists of a vessel which is open at the top
and contains a cylinder, the lower part of which has a number of holes and the top
of which supports a tube for admitting the air from the pipes h; a pipe
communicating with the machine B ends beneath the cylinder.
On the air being drawn by the machine, from the regulators D, D', and the
tubes,, the water contained in the vessels, will rise in the cylinders in proportion
to the rarefaction. There is, besides, on the cylinders a pipe provided with two
valves opening inwards. The latter receive their pressure from suitable weights
placed ou a suspended scale, so that they will not open until the rarefaction has
gone beyond the degree proportionate to the weight. By this means an exact and
self regulating limitation of the rarefaction has been obtained. The compression
of the air is also here indicated by means of a manometer filled with coloured
water.
The condensed air is warmed by means of the apparatus Ed represented on
Sheet II, in Figures 1 and 2. It consists of a cylinder E with an upper and
lower antechamber communicating by means of a number of tubes, through which
the condensed air has to pass in order to come to the tubes g, '. Two tubes
connect the cylinder E with a small reservoir d which is provided with a safety
valve. The steam produced in this reservoir, by means of a heating apparatus,
passes through the upper tube into the cylinder, between the two tubes, where it
yields its warmth, and condensed into water, runs back, through the lower tube,
into the basin to be again evaporated, and returns to the cylinder, and by this
constant circulation warms the air in the tubes. The cylinder is provided with two
valves, the one of which opening outwards, allows the air to escape from the space
around the tubes, when the steam enters the other opening inwards, allows the air
to enter when the process of heating is finished to prevent the tubes from being
damaged by rarefaction.
In order to mix some medicine with the condensed air the latter is led either
through a bottle F with two necks to Figure 4 of Sheet III, in which the medicine
in question has been made to drip on cotton, or through a bottle F¹, with three
necks to Figure 3, in which any liquid can be intermixed with the air by means of
a volatizer. The bottles are in vessels containing water and which can be warmed
by means of suitable gas burners. These bottles for the medicine volatilized can

compressed and heated air enters through an india rubber tube and the glass tube 1
into the reservoir F. Through another glass tube 3 to which is fixed the inhaling
tube with a valve and it passes towards the inhaling person.
The air which is in machine M is compressed to a higher degree comes through
tube m into the india rubber tube 2 and from there passes through a small glass
tube which latter has a pointed end.
Facing this pointed end is the equally pointed top of tube 4 the lower end of
which reaches into the medicine.
tube, at the same time sucking up the liquid coming from tube 4 and volatilizing
A sharp draught of air rushes out of the upper
same.
The current of air passing through the receiver takes with it the volatilized
medicine.
The tubes and h, have at suitable intervals openings to which the pipes leading
to the mouthpieces are fastened. The vessels destined for the reception of the
bottles F and F with the warming apparatus are fastened to the wall just below
them. There are besides single and double valves for the introduction of the
condensed air and the removal of the exhaled air; by a slight pressure of a finger
they permit the establishment of a connection with the condensed air as well as with
the rarefied air, the mouthpiece is joined to those valves.
When the machines A. and B as well as P are put in motion, provided all tubes
and bottles are in their proper places, several persons can at the same time perform
the following:-1. Inhale condensed air of different tensions and exhale into the
open air.
2. Exhale into air rarefied to different degrees. 3. Inhale air of
different degrees of compression intermixed with volatilized medicine and exhale
into the ordinary air. 4. Inhale air of different degrees of compression intermixed
with solutions volatilized and exhale into the ordinary air. 5. Inhale air of different
degrees of compression and exhale into air rarified to different degrees. 6. Inhale
air of different degrees of compression intermixed with medicine volatilized and
exhale into air rarified to different degrees. 7. Inhale hot air of different degrees of
compression with or without medicine and exhale into rarified air.
The pipes g, g', although covered with a material which is a bad heat conductor,
will partially give up to the surrounding air the warmth of the air passing through
them, so that the temperature of the compressed air coming out through the
penings will be gradually inferior, the more distant these openings are from the
varming apparatus. A selection of suitable wrappings and an arrangement which
permits an easy removal and replacing of these wrappings will render it possible to
egulate this diminution of warmth within certain limits and thus provide every
atient with a temperature best suited to his condition.
Having now particularly described and ascertained the nature of my said inven-
on, and in what manner the same is to be performed, I declare that what I
laim is :-
1. The combination of the apparatus for the inhalation of condensed air in every
onceivable manner and the exhalation into rarefied air, for curing diseases of the
espiratory organs and the air tubes of the human body, in a manner substantially
herein described and according to the accompanying drawings.
2. To vary the combination of the apparatus, either the shapes, materials
proportions of the various parts for the purpose substantially as herein set
rth.
