Year: 1862

page_text: LETTERS PATENT to John Savory, of the Firm of Savory and Moore, of
'Bond Street, in the County of. Middlesex, for the Invention of "A.
NEW OR IMPROVED APPARATUS FOR THE INHALATION OF MEDICINAL POWDERS
OR VAPOURS FOR THE TREATMENT OF DISEASES OF THE THROAT AND LUNGS.".
A communication from abroad by Dr. John Roberts, resident at Paris,
in the Empire of France.
Sealed the 16th June 1863, and dated the 18th December 1862.
PROVISIONAL SPECIFICATION left by the said John Savory at the
Office of the Commissioners of Patents, with his Petition, on the
18th December 1862.
I, JOHN SAVORY, of the Firm of Savory and Moore, of Bond Street, in the
County of Middlesex, do hereby declare the nature of the said Invention for
"A NEW OR IMPROVED, APPARATUS FOR THE INHALATION OF MEDICINAL POWDERS OR
VAPOURS FOR THE TREATMENT OF DISEASES OF THE THROAT AND, LUNGS," a com-
munication to me from abroad by Dr. John Roberts, resident at Paris, in the
Empire of France, to be as follows:-
This Invention consists of an apparatus, by means of, which medicinal
powders and vapours of all descriptions suitable to diseases of the throat and
lungs may be administered by the-medium. of inhalation.
The apparatus is to be constructed as follows:-I propose.to. mount on a

page_text: standard a vertical air tube, the lower part being closed. At or near the bottom
of this tube a number of perforations are to be made, which are to be enclosed
by a collapsible india-rubber air vessel; the top of the tube supports a mouth-
piece, formed either in wood or metal, at the side, and in communication with
which is a hollow globe or vessel having an opening for the insertion of the
powder, the opening being closed by means of a screw cap; the globe or
vessel receives the air tube at its lower part, and the powder is prevented from
falling into the tube by a ball or non-return valve; the communication
between the powder receptacle and the mouthpiece is established by the
medium of wire gauze, which prevents any particles of powder, except of the
finest nature, from entering the mouthpiece.
The operation of the apparatus will be easily understood. The patient
applies the mouth to the mouthpiece, and suddenly compresses the india-
rubber air vessel, whereby the powder is blown or forced into the lungs or
bronchial tubes, whether aided or not by inhalation.
In order to act upon vapours, such as the vapour of stramonium or resinous
vapours, it is only necessary to provide a vessel containing water and the
desired substance for inhalation, and to apply a spirit lamp to raise the tem-
perature sufficiently to obtain evaporation; a tube ascends from the top of
the vessel to the mouthpiece, the air tube enters the mouthpiece in the form of
a funnel or horn, the open end being nearest the mouth of the patient, and
being in some cases furnished with a rose. The operation is similar to that
in the former example, vapour being expelled from the apparatus into the
throat and lungs.

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Savory in the Great Seal Patent Office on the 18th
June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SAVORY, of the Firm of Savory and Moore, of Bond Street, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Savory, Her special licence, that I; the said John Savory, my
executors, administrators, and assigns, or such others as I; the said John

page_text: Savory, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "A NEW OR IMPROVED APPARATUS
FOR THE INHALATION OF MEDICINAL POWDERS OR VAPOURS FOR THE TREATMENT OF
DISEASES OF THE THROAT AND LUNGS," a communication to me from abroad by
Dr. John Roberts, resident at Paris, in the Empire of France, upon the con-
dition (amongst others) that I, the said John Savory, my executors or
administrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Savory, do hereby declare.
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement:-
This Invention consists of an apparatus, by means of which medicinal
powders and vapours of all descriptions suitable to diseases of the throat and
lungs may. be administered by the medium of inhalation.
The instrument or apparatus.consists of a receptacle of glass, metal, or any
other suitable material, into which are introduced impalpable powders, also
certain liquids, such as chloroform, creosote, &c. The powder or the vapour
of liquids are forced out of the receptacle by means of an india-rubber bottle
containing air, connected by an elastic tube. On the opposite side of the
receptacle is fitted a tube of ivory or glass perforated at its extremity with
small apertures to convey the powder or vapour into the throad and chest.
I will now proceed to describe the best means I am acquainted with for
carrying the said Invention into practical effect, as follows:-I mount on a
standard a vertical air tube, the lower part being closed. At or near the
bottom of this tube a number of apertures or perforations are to be made,
which are to be enclosed by a collapsible india-rubber bottle or air vessel;
the top of the tube supports à mouthpiece, formed either in wood, ivory, or
metal; at the side of and in communication with which is a hollow globe or
vessel having an opening for the insertion of the powder, the opening being
closed by a screw cap; the globe or vessel receives the air tube at its lower
part, and the powder is prevented from falling into the tube by a ball or non-
return valve; the communication between the powder receptacle and the

page_text: mouth piece is established by the medium of wire gauze, or other perforated
fabric, which prevents any particles of powder, except of the finest nature,
from entering the mouthpiece.
The mode of using the instrument is as follows:-Having introduced the
powder or liquid into the receptacle, the mouthpiece is put into the mouth
nearly to the throat, the mouth being kept wide open; then a full inspiration
should be taken, and at the same instant the .india-rubber. bag should be
pressed quickly; by these means the powder or vapour will be made to
penetrate to the throat, larynx, windpipe, and air passages of the lungs.
In order to act upon vapours, such as the vapour of stramonium or resinous
vapours, it is only necessary to provide a vessel containing water and the
desired substance for inhalation, and to apply a spirit lamp to raise the tem-
perature sufficiently to obtain evaporation; a tube ascends from the top of the
vessel to the mouthpiece; the air tube enters the mouthpiece in the form of a
funnel or horn, the open end being nearest the mouth of the patient, and
being in some cases furnished with a rose. The operation is similar to that
in the former example, vapour being expelled from the apparatus into the
throat and lungs.
I simplify the foregoing apparatus, when desired, by dispensing. with the
stand, and using the collapsible bottle, the flexible tube, the receptacle, and
the mouthpiece, as described, the object and results being the same.
To render the application of medicinal powders to the lining membrane of
the throat and chest more general, it has become necessary to simplify the
process, and provide the public with a cheap instrument for that purpose.
This instrument may be used with great advantage in the treatment of
affections of the throat, larynx, trachea, and air passages of the lungs; also
in some forms of deafness. The instrument enables medical men to admi-
nister by way of respiration a great variety of remedies in exact doses. The
powders or vapours to be used with this instrument must vary according to
the nature of the disease. On this point the medical attendant will decide.
From the foregoing description, the apparatus, which is of simple construc-
tion, will very readily be understood, as well as the method of its application
and the objects it is intended to effect. I would remark, in conclusion,
that I do not restrict myself to the precise details I have expressed, as it is
obvious that the same may be modified without in any way departing from the
principles on which the said Invention is based; but what I claim and desire
to be secured to me by the herein in part recited Letters Patept, are, the
general arrangement and combination of parts as herein specified, or any
others substantially to all intentsand purposes the same, constituting "An

page_text: Apparatus for the Inhalation of Medicinal Powders or Vapours for the
Treatment of Diseases of the Throat and Lungs," as herein set forth.
In witness whereof, I, the said John Savory, have hereunto set my hand
and seal, this Seventeenth day of June, in the year of our Lord One
thousand eight hundred and sixty-three.
