Improved Apparatus to be Used for Inhaling Vapor of Chloride
of Ammonium.
1 JAMES WILLIAM POWNALL of 17 Bishop Street Moss Side Manchester in the
County of Lancaster Cashier do hereby declare the nature of this invention to be as
follows
The object of my invention is to improve the apparatus employed for inhaling the
vapour of chloride of ammonium by so constructing the same that the length of the
ubing shall be considerably reduced, the combination of the acid and ammonia gases
shall be rendered almost instantaneous whereby the quality of the vapour is improved,
and the possibility of corrosion of any portion of the apparatus by the acid or the
ammonia shall be removed.
I use three glass vessels one for the water, one for the hydrochloric acid, and one
for the ammonia liquor. They are however arranged and connected in a special
manner,
and the vessels or chambers for the acid and the ammonia liquor are of a
novel construction.
These vessels or chambers are entirely made of glass and are cylindrical in form with
flat ends. From the centre of the end intended for the bottom rises a hollow tube
passing upwards an i inwards to within a sufficient distance from the opposite end of
the chamber (intended for the top) to allow a free passage of air, without allowing
any finid to escape through the tube which is open at top and bottom.
In the top part of the chamber near to the outer elge thereof a hole is drilled or
formed so as to allow of the in-ertion of a small glass fimnel by which fluid may he
poured into the chamber and also to admit a current of air as hereinafter described.
These chambers fit upon the arms of a iwo branched glass syphon pipe or tube the
stem of which in turn is fitted into the stopper of a bottle or vessel containing water,
to near the bottom of which the said stem extends.
In the same stopper is also fixed a shori glass tube which only passes into the
bottle without touching the water, and to the outer portion of this is attached an
india rubber tube with a glass or other mouthpiece.

page_text: The joints between the acid and ammonia chambers and the two branched pipe,
and between the latter and the stopper of the water bottle are made gas and liquid
tight by short pieces of india rubber tubing and it will be evident that, owing to the
peculiar construction of the acid and ammonia chambers neither of these liquids can
come in contact with these india rubber packings or with any thing else but the
interior of the glass chambers, and hence no corrosion can take place.
This apparatus is used as follows: the water vessel being filled to a convenient
height, and the stopper and two branched pipe properly fixed, one of the glass
chambers is fitted onto the upper end of each branch, and these two chambers are
charged with hydrochloric acid, and dilute ammonia respectively to such a level as
will cover the bottom end of the glass funnel but not reach up to the top of the
central tube.
Suction being now applied to the mouthpiece attached to the water bottle air will
be drawn in through the two glass funnels bubbling through the acid and ammonia,
and displacing the gases which will simultaneously pass along the two branch-pipes,
and mingling in the stem the combined gases will then pass through the water in the
form of vapor which is thus inhaled.

Improved Apparatus to be Used for Inhaling Vapor of Chloride
of Ammonium.
I JAMES WILLIAM POWNALL of 47 Bishop Street Moss Side Manchester in the
County of Lancaster Cashier do hereby declare the nature of this invention and in
the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
what manner
The object of my invention is to improve the apparatus employed for inhaling the
vapor of Chloride of Ammonium by so constructing the same that the length of the
tubing shall be considerably reduced, the combination of the acid and ammonia gasses
shall be rendered almost instantaneous whereby the vapor is improved, the possibility
of corrosion of any portion of the apparatus by the acid or the ammonia shall be
removed, and the formation of deposit within the tubes prevented.
I use three glass vessels one for the water, one for the hydrochloric acid, and one for
the ammonia liquor. They are however arranged and connected in a special manner,
and the vessels or chambers for the acid and the ammonia liquor are of a novel con-
siruction.
These vessels or chambers are entirely made of Glass and are cylindrical in form
with flat ends-From the centre of the end intended for the bottom rises a hollow
tube (A) passing upwards and inwards to within a sufficient distance from the
opposite end of chamber (intended for the top) to allow a free passage of air, without
allowing any fluid to escape through the tube which is open at top and bottom.
In the top part of the chamber near to the outer edge thereof a hole (B) is drilled
or formed so as to allow of the insertion of a small Glass funnel by which fluid may
be poured into the chamber and also to admit a current of air as hereinafter described.
These chambers fit upon the arms of a two branched glass syphon pipe or tube (C)
the stem of which in turn is fitted into the stopper of a bottle (E) or vessel containing
water, to near the bottom of which the said stem extends.
In the same stopper is also fixed a short glass tube which only passes into the
bottle without touching the water, and to the outer portion of this is attached an
india rubber tube (D) with a Glass or other mouthpiece.
The joints between the acid and ammonia chambers and the two branched pipe and
between the latter and the stopper of the water bottle are made gas and liquid tight
by short pieces of india rubber tubing and it will be evident that owing to the peculiar
construction of the acid and ammonia chambers neither of these liquids can come in
contact with these india rubber packings nor with anything else but the interior of
the glass chambers and hence no corrosion can take place. Further the Chambers
being removable at will from off the branches of the stem no formation of deposit can
take place within the tubes.
This apparatus is used as follows-the water vessel (E) being filled to a convenient
height and the stopper thereof properly fixed one of the Glass chambers is fitted on

page_text: to the upper end of each branch of the two branched stem these two chambers are
charged with hydrochloric acid and dilute ammonia respectively by means of Glass
funnels placed in the air holes (B. B.) to such a level as will cover the bottom end of
the funnel but not to reach up to the top of the tubes A A. The funnels are then
removed and the Inhaler is ready for use.
Suction being now applied to the mouthpiece of the tube D attached to the water
bottle, air will be drawn through the holes B. B. on to the surface of the acid and
ammonia and displacing the Gasses which will simultaneously pass along the
tubes A A and the two branched pipe and mingling in the stem the combined Gasses
will pass through the water in the form of vapor which is thus inhaled.
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
The use of the Glass chambers or Bottles for the acid and ammonia made arranged
and connected as described.
