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:
The invention consists of an inhaling apparatus constructed so as to be used
either for inhaling hot filtrated air or dry or wet vapours of any suitable medicinal
product or both.
The base of the apparatus consists of two portions which are intended to contain
a reserve of medicinal products to be used with the apparatus. The said base
carries a cylindrical casing having a laterally extending portion and containing
an alcohol-lamp. The cylindrical casing is provided with openings and carries the
boiler traversed by the stove which provided with a cover which latter when
shut causes the lamp to be extinguished.
The boiler is provided with a double wall forming an air-gap around the inner
portion which contains the water to be vaporised.
The inner portion is provided with a safety-valve. The steam produced in the
said inner portion is used either in the left portion of the apparatus or in the right
one or in both at the same time if two persons use the apparatus at once.
The left portion of the apparatus consists of a cock connected by one tube to the
inner portion of the boiler, by a second tube to the water bag or receptacle and by a
third tube to the infusing vessel.
If water is to be filled into the boiler the water receptacle is first withdrawn and
the second tube then allows the water to escape and to indicate that the same has
reached the desired level in the boiler.
In the infusing vessel there are provided two sieves intended to carry material
to be fused and prevent it falling down into the cock. The top of the infusing
vessel carries a removable horizontal tube to which is affixed an adjustable carrier
which supports a glass-tube and a drop-cup,
If steam is produced in the boiler and if the cock is open, the said steam is
caused to traverse the material contained in the infusing apparatus and to escape
from the removable tube through the glass-tube into the mouth of the person
using the apparatus.
The right-hand portion of the apparatus is constructed as follows:
The air-gap of the boiler is connected by means of a tube to an air-filter in which
a suitable sterilizing material is contained. The said tube and filter are placed
in line with the tube connecting the air gap with the chamber or laterally extend-

page_text: ing part of the base for the purpose of rendering the working of the apparatus
easy to understand, but in reality the said air filter tube and filter are placed at
any other point of the circumference of the air-gap of the boiler for the purpose
of causing the air entering this filter to circulate within the air-gap before escaping
into the said tube.
The aforesaid connecting tube between the air-gap and the chamber has
arranged parallel thereto a steam-tube. The said steam tube is connected to a tube
of the boiler and has a cock intended to put the right-hand portion of the apparatus
in or out of action; The said chamber which is provided with a condensed steam
receptacle and a blow off cock, there is provided a vertical tube in the bottom of
which a perforated box is arranged for the purpose of containing a suitable
medicine through which the steam will be obliged to pass before escaping through
the tube and flexible pipe into the mouth of the patient. The vertical tube con-
tains a series of superposed conical partitions provided with suitable holes for
causing the steam passing the said tube to take an irregular course, and to be
thereby cooled.
The conical partitions are connected with one another and with the top-piece
by means of a rod, so that when the top-piece is withdrawn the said partitions are
also withdrawn to allow the tube to be easily cleaned.
The top-piece is a valve-box in which a return-valve and a blow-valve are
arranged. The return valve is formed of a star-shaped plate which is free to move
up and down and is guided by its points. The blow-valve is formed of a disc
which is also free to move up and down. Over the latter valve there are provided
several openings. The cover of the top-picce is removable.
The nozzle of the top piece is provided with a flexible pipe to which a mouth-
pieco is affixed.
If steam is produced in the boiler and if the cock in the steam tube is open,
the steam entering the casing or chamber through the tube causes a suction to be
produced in the connecting tube, and the air, entering the filter and circulating
in the air-gap to pass with the said steam through the medicine contained in the
receptacle therefor, the conical partitions and the return valve to the flexible
pipe and mouth-piece.
In some cases the flexible pipe will preferably be provided with a water-pot
receptacle fixed to an intermediate pipe inserted substantially in the middle of
the length of the said flexible pipe.
In a modified form of the medicine tube the said tube is combined with
a concentrical inner tube and with a cover having suitable openings. The
medicine is placed between the tubes and the steam entering the latter is thrown
back by the cover upon the said medicine and then escapes through the openings
into the vertical tube in the manner above described.
When the vapours escaping from the infusing apparatus are to be mixed with
a pulverized liquid the tube leading from such apparatus is then combined with
suction pipe plunging into a glass containing the liquid medicine and placed in
the drop-cup. This device works in the well-known manner for inhaling steam
and a pulverized liquid.
In a modified form of condensed steam pot the latter is provided with several
openings over which a screen is arranged the purpose of which is to control the
openings. These openings are intended to allow the steam which may enter the
pot to escape.

page_text: Improvements in Apparatus for Facilitating the Inhalation of
Medicinal Vapours.
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 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 an inhaling apparatus constructed so as to be used
either for inhaling hot filtrated air or the dry or wet vapours of any suitable
medicinal product or both, and is illustrated in the accompanying drawings, in
which
Figure 1 is a vertical section through the apparatus.
Figures 2 and 3 show in side-view and plan a modified construction of the
mouth-piece.
Figures 4 to 7 show modifications of several portions of the apparatus shown
in Figure 1.
In all the figures of the drawings like letters of reference refer to corresponding
parts.
The base of the apparatus consists of two portions A and A which are intended
to contain a reserve of medicinal products to be used with the apparatus. The
said base carries a cylindrical casing B₁ containing an alcohol-lamp C. The
case B is further provided with a laterally extending portion B² hereinafter
referred to. The cylindrical casing B¹ is provided with openings 6 and carries
the boiler B traversed by the flue B3 which is provided with a cover b³, which
latter when shut causes the lamp to be extinguished.
The boiler 1 is provided with a double wall forming an air space 6+ around the
inner portion which contains the water to be vaporized.
The inner portion 63 is provided with a safety-valve 6. The steam produced
in the said inner portion 63 is used either in the left hand portion of the apparatus
or in the right hand one or in both at the same time if two persons use the apparatus
at once.
The left hand portion of the apparatus consists of a cock D D¹ connected by a
tube d to the inner portion 63 of the boiler, and by a second tube d³ to the water
bag or receptacle E, and by a third tube ³ to the infusing vessel F.
If the boiler 63 is filled with water the water receptacle E being first withdrawn,
the tube then allows water to escape and to indicate that the same has reached
the desired level in the boiler.
In the infusing vessel F, there are provided two sieves f¹ and 2 intended to
carry material to be infused and prevent it falling down into the cock 1) D. The
top of the infusing vessel carries a removable horizontal tube G to which is affixed
an adjustable carrier 9 which supports a glass-tube H and a drip-cup I.
If steam is produced in the boiler and if the cock D D is open, the said steam
is caused through passage d³ to traverse the material contained in the infusing
apparatus and to escape from the removable tube G through the glass-tube H
into the mouth of the person using the apparatus.
g' is a screw cap adapted to be screwed upon the tube G when said tube is not
in use.
The right-hand portion of the apparatus is constructed as follows:
The air-space or gap b4 of the boiler B is connected by means of a tube K¹ to an
air-filter K in which a suitable sterilizing material k is contained. The said tube K¹
and filter K are placed on the drawing in line with the tube L, for the purpose
of rendering the working of the apparatus easy to understand, but in reality the

page_text: said air filter tube K and filter K are placed at another point of the circum-
ference of the air-space of the boiler, for the purpose of causing the air entering
the filter K to circulate within the air-gap before escaping into the said tube L.
The aforesaid tube L connects the air-gap 6 with the chamber B2 in which a
steam tube M' is arranged parallely to the tube L. The said steam tube M¹ is
connected to a tube B5 of the boiler and is provided with a cock M² intended to put
the right-hand portion of the apparatus in or out of action; b+ is a blow-off cock.
On the casing B, which is provided with a receptacle S for condensed steam is
provided a vertical tube in the bottom of which a perforated box N is
arranged for the purpose of containing a suitable medicine through which the steam
will be obliged to pass before escaping through the tube and the flexible pipe Q
into the mouth of the patient. The vertical tube O contains a series of superposed
conical partitions of, 02, 03, of provided with suitable holes for causing the steam
passing the said tube O, to take an irregular course in the manner shown by the
arrow in the drawing and to be thereby cooled.
The conical partitions o', o², 0³, o, are connected with one another and with
the top-piece I by means of a rod 01, so that when the top-piece P is withdrawn
the said partitions o¹, 02, 03, 04, are also withdrawn to allow the tube O to be easily
cleaned.
The top-piece P is a valve-box in which a return-valve p³ and a blow through
valve 22 are arranged. The return valve p¹ is formed of a star-shaped plate which
is free to move up and down and is guided by its points. The blow through
valve 2 is formed of a disc which is also free to move up and down. Over the
said valve there are provided sevoral openings 2³. The cover 12 of the top-piece P
is likewise removable.
The nozzle 1 of the top piece is provided with a flexible pipe Q to which a
mouth-piece R (Figure 1) or R1 (Figures 2 and 3) is affixed.
If steam is produced in the boiler and if the cock in the steam tube is open, the
steam entering the casing B2 through the tube M¹ causes a suction to be produced
in the connecting tube, L and the air, entering the filter K and circulating in the
air-gap 4, to pass with the said steam through the medicine contained in
receptacle N, the conical partitions o¹ 0 0³o and the return valve p' to the flexible
pipe Q and mouth-piece R.
In some cases the flexible pipe Q will preferably be provided with a water
receptacle q, fixed to an intermediate pipe Q inserted substantially in the middle
of the length of the said flexible pipe Q as shown in Figure 4.
In a modified form of the medicine-tube N¹ Figure 5, intended to replace the
perforated tube N of Figure 1, the outer tube thereof is combined with a con-
centric inner tube and with a cover N° having suitable openings 3. The
medicine is placed between the tubes N and ¹ and the steam entering the latter
as shown by the arrow 1 is thrown back by the cover N2 upon the said medicine
and then escapes through the openings into the vertical tube O in the manner
above described with reference to Figure 1.
Figure C shows how the tube G may be arranged when the vapours escaping
from the infusing apparatus F are to be mixed with a pulverized liquid.
The said tube G is then combined with a suction pipe G¹ dipping into a glass I',
containing the liquid medicine and placed in the drip-cup I. This device works
in the well-known manner for inhaling steam and a pulverized liquid.
In a modified form of condensed steam pot or receptacle S the latter is provided
with several openings s over which a screen s¹ Figure 7 is arranged, the purpose
of which is to control the openings s. These openings are intended to allow the
steam which may enter the pot S to escape.
