WILLIAM MARTINDALE, of No 10, New Cavendish Street, Portland Place, in the
County of Middlesex, Pharmaceutical Chemist "IMPROVED APPARATUS FOR
INHALING MOIST AIR OR MEDICATED VAPOUR"
My Invention has reference to apparatus for inhaling moist air or medicated
vapour Many arrangements of apparatus for this purpose are at present in use,
but so far as I know they are all more or less open to objection on the following
grounds, that is to say -Some involve undue exortion on the part of the user, some
are complicated and expensive, and in some the au inhaled does not pass through or
agitato the medicated liquid so as to become efficiently impregnated with the
medicine Now iny Invention is designed to produce a simple, cheap, and efficient
inhaling apparatus, where the air shall be duly charged with the medicine, whilst
the exertion on the part of the user is reduced to a minimum To this end I
employ a wide mouthed vessel, I call a receiver, in conjunction with a cover mainly
of conical or tapering form terminating in a mouth-piece, the icceiver and cover
when together constituting an inner chamber and an outer chainber, the latter
usually of annulai form The two chambers communicate with each other through
openings a short distance below the level of the liquid with which the apparatus
is changed, and whose surface is in the outer chambei exposed to the air
The receiver and cover may be either separable or permanently connected
In one arrangement inside the mouth of the receiver a short distance from the
top is a ledge for the upper portion of the apparatus to rest upon, that portion
being in this case separate and removeable It may be made capable of being
attached to the receiver by a bayonet catch The upper portion or cover near or at
its base is either pierced with holes or indented, or it may be plain, the holes or
indentations being then made in the ledge inside the mouth of the receiver on
which this upper portion or cover rests A larger hole or indentation may be made
at one point of the base or circumference of the upper portion or cover of the
apparatus for the purpose of allowing a thermometer to be passed into the liquid
contained in the receiver, or the receiver may have a spouted aperture to admit of
the thermometer being passed into it, and the thermometer may be safely packed
within the apparatus when made with a removeable mouth-piece The top of the
upper portion is shaped into a mouth-piece with a suitable aperture, or the mouth-
picce may be made capable of being detached, and may have either a simple aperture
or contain a double valve arrangement

page_text: The apparatus may be covered with a woollen cover to prevent the rapid lowering
in temperature of the fluid contained in it
In a modification of the apparatus the base of the upper portion may be con-
tinued below the row of holes, so as to be placed in and to rest on the bottom of
the receiver, which in this case may be an ordinary gallipot, the sides of which will
rise somewhat above the row of holes
As already stated instead of making the apparatus with the upper portion or
cover removeable, the latter may be in one with or permanently connected to the
receiver
When charged for use the apparatus should be filled with water or medicated
liquid of the requied temperature, until the holes establishing communication
between the two chambers are slightly below the surface of the liquid, the distance
being adjusted to suit the user When he inhales by the mouth-piece, the air he
will inspire (and this with ease) will have passed through the liquid in the
apparatus with a gurgling noise, and will have become pioperly medicated
