of Middlesex, India Rubber Manufacturer, do hereby declare the nature of this.
invention to be as follows:-
The invention has for its object an improved inhaler which involves no waste of
drug or preparation, is easily cleaned and is always ready for use.
For this purpose I employ a pot of any suitable shape and material and
preferably provided with a handle. This pot is also provided with a cover fitting
over the top thereof; this cover is provided with a central short tube or opening
through which is passed an india rubber inhaling tube the lower end of which
latter is formed with a thickened rib or ring around the same so that by drawing it
up against the interior of the cover a tight joint is made at such part.
The cover is also preferably provided with air holes or provision may be
otherwise made to admit air so as to allow the vapour to be drawn off freely.
The pot is provided with a central holder to receive a small bottle or jar to
contain the drug or preparation and this guide is so formed as to give free access of
the hot water in the pot to the exterior of the bottle or jar.
In using the inhaler the bottle or jar is supplied with a drug or preparation, the
pot is supplied with a quantity of hot water and the bottle or jar is placed in its
holder in the hot water: the cover is then placed over the pot and the patient
applies the free end of the rubber tube or a mouth piece fitted thereto to his
mouth when he will be enabled to inhale the vapour given off.
The cooled water can be readily thrown away after first removing the bottle or
jar from the pot and a fresh supply of hot water can be placed in the pot from
time to time as may be required.

COMPLETE SPECIFICATION.
Improvements in Inhalers.
I, JAMES GEORGE INGRAM of Felstead Street, Hackney Wick, in the County
of Middlesex, India Rubber Manufacturer do hereby declare the nature of my
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement
The invention has for its object an improved inhaler which involves no waste of
drug or preparation, is easily cleaned and is always ready for use.
For this purpose I employ a pot of any suitable shape and material and preferably
provided with a handle. This pot is also supplied with a cover fitting over the
top thereof; this cover has a central short tube or opening through which is passed
an india rubber inhaling tube the lower end of which latter is formed with a
thickened rib or ring around the same so that by drawing it up against the interior
of the cover a tight joint is made at such part.
The cover is also preferably provided with air holes or provision may be
otherwise made to admit air so as to allow the vapour to be drawn off freely.

page_text: The pot is provided with a central holder or guide to receive a small bottle or
jar to contain the drug or preparation and this holder or guide is perforated or so
formed as to give free access of the hot water in the pot to the exterior of the
hottle or jar.
In using the inhaler the bottle or jar is supplied with a drug or preparation, the
pot is supplied, with a quantity of hot water care being taken that the hot water
shall not reach the top of the bottle or jar when placed therein, the bottle or jar is
placed in its holder in the hot water, the cover is then placed over the pot and the
patient applies the free end of the rubber tube, or a mouth piece fitted thereto, to his
mouth when he will be enabled to inhale the vapour given off. The cooled water
can be readily thrown away after first removing the bottle or jar from the pot and
a fresh supply of hot water can be placed in the pot from time to time as may be
required. If desired the inhaler may be placed on a hob or fire or in an oven to be
kept hot and always ready for use.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
Figure 1 is a vertical section and Figure 2 is a plan of my improved inhaling
apparatus. Like parts are indicated by similar letters of reference.
In carrying my invention into effect I employ a pot a of any suitable shape and
material provided with a handle a', and cover a fitting over the top of the said
pot. This cover a² has a central opening through which is passed an india rubber
inhaling tube b the lower end of which is formed with a thickened rib or ring b¹
around the same so that by drawing it up against the interior of the cover a² a
tight joint is made at such part. In some cases I fit the cover a' with a short
guiding tube through which passes the india rubber tube b. The cover a is also
preferably provided with air holes a³ to admit air so as to allow the vapour to be
drawn off freely or other convenient means may be employed.
The pot a is provided with a central holder or guide c to receive a small bottle
or jar d, shown in dotted lines in Figure 1 and in full lines in Figure 2 which
contains the drug or preparation to be inhaled and this holder or guide c is
perforated as shown or is otherwise formed so as to give free access of the hot
water in the pot a to the exterior of the bottle or jar d.
In using the inhaler the bottle or jar d is supplied with a drug or preparation
and the pot a is partly filled with hot water, care being taken that the hot water is
not high enough to enter the bottle or jar when placed therein. The bottle or jar
is placed in its holder c in the hot water, the cover a is then placed in position and
the patient applies the free end of the tube or mouth piece b¹ fitted thereto to his
mouth when he will be enabled to inhale the vapour given off.
The cooled water can be thrown away after first removing the bottle or jar d
from the pot and a fresh supply of hot water can be placed in the pot from time to
. time as may be required.
By the use of my apparatus a great saving is obtained compared with the
usual method of mixing the drug or preparation with the hot water which when
cool is thrown away:
Having now particularly described and ascertained the nature of my said inven
tion and in what manuer the same is to be performed I declare that what
I claim is :-
1. An inhaler consisting of a pot provided with a closely fitting perforated
cover having a central hole through which is passed a tube having a rib or flange
around its lower end to form a tight joint said pot containing a holder or guide so
formed that the hot water may have free access to the exterior of the bottle or jar
placed therein containing the desired drug or preparation substantially as herein
shown and described.

page_text: 2. The peculiar arrangement and combination of parts forming an inhaler
substantially as herein shown and described.
