PROVISIONAL SPECIFICATION.
A Pocket Inhaler or Respirator.
I WILLIAM WASHINGTON HOULDER of 10 Ossulton Villas, Southall in the
County of Middlesex, Chemical Manufacturer do hereby declare the nature of
this invention to be as follows:-
The pocket inhaler or respirator herein described consists mainly of a receptacle
or box (D, in drawing herewith) to which is fitted tubes E E E so joined together
and fitted with valves as to permit the air to be drawn through the receptacle and
its contents but cause the used air to be exhaled outside.
The
One of the valve-tubes is connected to a flexible tube with mouthpiece E long
enough to allow the inhaler to be carried in a breast pocket when in use.
receptacle is charged by placing within any sufficiently divided material which
allows free passage of air between its interstices, as shavings of paper or fine
shavings of wood, loosely packed, and soaked in the oil or liquid the vapor of which
is to be inhaled.
The body of the receptacle D. may be of any hard material not affected by
the vapors to be inhaled, as well as the tubes and valves E E E. The body
may be of any shape or size suitable for the pocket, allowing the air to traverse
two inches of the saturated shavings; but the shape is preferably like a rather flat
or oval canister with a lid fitted at the inhaling end or front for charging or
cleaning, and at the opposite end or back holes are perforated for admission of the
air traversing the saturated shavings. If made of oval sides the inhaler when in
use rests on one narrow side of its circumference while the valve-tubes project
upwards and through the opposite narrow side; but if the body be made cylindrical
with flat lid and bottom, I place the perforations part way up in the sides, but
sufficiently high from the bottom to retain any drainings and the valve-tubes
project through the lid. In any case the body may be plain in shape or orna-
mented. In the flattened or oval form, to retain the drainings, I fasten (adapted
to the shape of the box) a crescent shaped piece or ridge near the lid in front as
at C, and the perforations at the end opposite I keep from the low narrow side to
correspond.
The valve-tubes I keep mainly within the body of the inhaler, but two ends
project through, and are secured in suitable apertures on the top or side which acts
as such, one end being for the flexible tube to the mouth, the other for exit of air.
Or the lower end of the inhaling tube may alone pierce the body and the other
portions of the valve-tubes remain outside. The seats of the valves and covers
may be either of metal, wood, or cork made smooth and true. The valves may be
of any hard smooth substance sufficiently light to form no impediment to respira-
tion, yet heavy enough to work perfectly free unattached in their places and by
their own weight. For this purpose I prefer bone, ivory or vulcanite. The tube
to the mouth may be of any flexible impervious material fitted with suitable
mouthpiece and of any desired length.

The receptacle is charged by placing therein any sumciently suitable material
which allows a free passage of air between its interstices as shavings of paper or
fine shavings of wood, loosely packed and soaked in any suitable preparation, the
vapor of which is to be inhaled.

d the container & air chamber which may be of any suitable size, shape. &
material convenient for fitting in breast pocket. Within this container or air
chamber are fitted flap valves i & ¹ enclosed by tubes e & e² communicating with
each other by a third horizontal tube e'. These valves i & i¹ consist of a strip of
light material, loosely hinged to the tubes e & e². These valves i & i¹ are placed
so as when the user inhales, one valve i opens & allows air from inlet
to pass up
the tube e, at same time closing the other valve but when he exhales the valve i
in the tube e which communicates with the air chamber d is closed, and the outlet
valve opened, which excludes the exhaled air from entering the air chamber d &
allows same to pass out by port h. A flexible pipe f & mouthpiece / is connected
to the port which is in communication with the air chamber & container d. Within
the said air chamber and container I provide a receptacle c. to catch the condensed
vapour. j movable lid.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
(1.) The combined respirator and inhaler consisting of an air chamber and con-
tainer, of oval or other shape made of metal, indiarubber or other suitable material
provided with ports, flap valves & receptacle c flexible tube and mouthpiece, air
holes in outer casing substantially as described.
(2.) In respirators & inhalers the employment of flap valves i whereby the
vitiated air is prevented from entering the chamber d. and vitiating the air therein.
