the City of London; Patent Agent and Engineer, for an Invention of
"IMPROVEMENTS IN INHALATION CHAMBERS." A communication from abroad

PROVISIONAL SPECIFICATION left by the said Walter Alfred Barlow at:
the Office of the Commissioners of Patents on the 17th January 1882.
WALTER ALFRED BARLOW of 6 St. Paul's Churchyard in the City of London.
Patent Agent and Engineer "IMPROVEMENTS IN INHALATION CHAMBERS." A
communication from abroad by Messieurs L'Encausse et Canésie of Paris France.
The object of this Invention is improved construction of chambers for inhalation
purposes and consists of:-A chamber in which is placed a cylinder made with its
surrounding portion of perforated iron plates and fixed to the floor of the
chamber.
At the top of the said cylinder is a tank' which may be continually cooled by
means of a tap and an overflow pipe.
A funnel in the middle of which is a steam pipe is placed inside the cylinder
and at the bottom side of the funnel a waste pipe is fixed. Between the funnel
and the perforated plate is a space with which an exhaust pipe is in
communication.
"
The steam is passed on to medicinal substances of which a certain part is carried
away and arrives to the funnel through the steam pipe and passes through the
holes made in the cover of the funnel and comes into contact with the cold tank,
the water of condensation falls to the bottom of the funnel and is driven off by
means of the waste pipe the steam not condensed passes through the holes of
the perforated iron plate of the cylinder and is diffused in the inhalation chamber.
The gases produced by breathing of persons under the treatment in the chamber
being heavier than steam in its gaseous state will fall to the bottom of the chamber
and will be carried away by means of the exhaust pipe..
This apparatus may be used as stated or be fitted to the room of a "Turkish "
or vapour bath.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Walter Alfred Barlow in the Great Seal Patent Office on the
17th July 1882.
WALTER ALFRED BARLOW of 6 St. Paul's Churchyard in the City of London
Patent Agent and Engineer "IMPROVEMENTS IN INHALATION CHAMBERS." A
communication from abroad by Messieur L. Encausse et Canésie of Paris, France.
The object of this Invention is improved construction of chambers for inhalation
purposes. In order that the said invention may be readily understood I have
hereunto annexed a sheet of drawings wherein is represented this improved
construction of inhalation chamber.
A is a chamber in which is placed a cylinder B made with its surrounding
portion of perforated iron plate C, and fixed to the floor of the chamber A.
At the top of the said cylinder is a tank D which may be continually cooled by
means of a tap R and an overflow pipe S.
A funnel E in the middle of which is a steam pipe G is placed inside the cylinder
and at the bottom side of the funnel a waste pipe H is fixed. Between the
funnel E and the perforated plate C is a round space K with which an exhaust
pipe M is in communication.
The following are the advantages of this new construction. The steam is passed
into medicinal substances of which a certain part is carried away and arrives to the
funnel E through the steam pipe G and passes in through the holes made in the
cover N of the funnel and comes into contact with the cold tank D; the water of
condensation falls to the bottom of the funnel E and is driven off by means of the
waste pipe H; the steam not condensed passes through the holes of the perforated
iron plate C (perforated from a to b) and is diffused in the inhalation chamber.
The gases produced by breathing of persons under the treatment in the chamber
being heavier than steam in its gaseous state will fall to the bottom of the
chamber and will be carried away by means of the exhaust pipe M and through
the space K.
The height of the cylinder B is about two feet eight inches. This invention
provides an inhalation chamber of the best construction and the apparatus may be
used fitted to the room of a "Turkish
or vapour bath.
"
Having now described the nature and particulars of the said Invention I
claim
An inhalation chamber with an apparatus B as described in combination with
pipes therein with the funnel E, the iron plate M and the cooling tank D constructed
and operating as and for the purpose herein set forth.
In witness whereof I' the said Walter Alfred Barlow have hereunto set my
hand and seal this Fourteenth day of July in the year of our Lord One
thousand eight hundred and eighty two.
