ANTHONY BELL, of the Town and County of Newcastle-on-Tyne, Physician and
Surgeon. IMPROVEMENTS IN APPARATUS FOR RENDERING AN ATMOSPHERE

MEDICAMENTS FOR THE PURPOSES OF RESPIRATION AS A CURATIVE OR PALLIATIVE
AGENT IN PULMONARY OR OTHER AFFECTIONS, PART OF WHICH INVENTION IS

The object of my Invention is to administer to a person suffering from diseases or
disorders of the throat, chest, or other parts affected, the remedial agent in such a
manner that it may be applied directly with little or no distress to the most
enfeebled patient.
"
The means I employ to carry out my Invention are as follows:-A wheel or set
of vanes or blades for the purpose of charging the atmosphere with dry medicaments
is keyed upon an axle supported in a suitable frame, with a hopper or receptacle
attached to contain the medicaments intended to be used. The said wheel when
in action revolves with the said hopper. A stream of air is directed upon the dry
nedicaments carried by the said wheel by means of a tube or pipe proceeding from
a fan or blower, and then passes along a flexible or other suitable tube to the patient's
mouth and is respired.
.
The fan and the wheel (which may have a grooved or plain periphery) or set of
vanes or blades are when in action made to revolve by any ordinary means, and

page_text: the quantity of medicaments discharged by the wheel on to or in a line with a
stream of air regulated by a suitable regulator.
To render the air or atmosphere antiseptic before it is discharged with the curative
agent I cause it to pass through an antiseptic or purifying medium previous to its
employment as a inedicated vehicle.
When the above described apparatus is to be used for the purpose of rendering
air in a room antiseptic I disconnect the medicament wheel, and placing the said
apparatus in communication with the air or atmosphere set it in motion by any
approved means; but if a tube leading from the outer air be attached to the instru-
ment fresh air would be rendered antiseptic. This would be of great advantage in
the treatment of diseases of a typhoid character, or of such surgical cases as present
a foul or malignant character.
It is evident from the foregoing that not only may the atmosphere of a room or
chamber be charged with an antiseptic, but it may be perfumed or charged if
required with an agent producing when respired a healing, soothing, stimulating,
absorbent, or other desirable effect upon the patient; these different effects may be
obtained by charging the aforesaid hopper with the requisite ingredients, and
leaving the mouth of the tube piece free to discharge its stream into the room.

ANTHONY BELL, of the Town and County of Newcastle-on-Tyne, Physician and
Surgeon. "IMPROVEMENTS IN APPARATUS FOR RENDERING AN ATMOSPHERE
ANTISEPTIC AND CHARGING IT IN DETERMINATE PROPORTIONS WITH DRY
MEDICAMENTS FOR THE PURPOSES OF RESPIRATION AS A CURATIVE OR PALLIATIVE
AGENT IN PULMONARY OR OTHER AFFECTIONS, PART OF WHICH INVENTION IS
ALSO APPLICABLE FOR THE PURPOSE OF RENDERING AIR IN A ROOM ANTISEPTIC."
My Invention relates to treating and applying air for curative and other purposes.
By its ineans a current of air may be rendered antiseptic (with or without previous
warming), charged with a dry medicament or medicaments in any suitable pro-
portion, and administered to a patient; or the air rendered antiseptic, but not
medicated, may be discharged into a room or apartment to render the atmosphere
therein antiseptic for surgical or other purposes. A fan or blower suitably driven
draws air through carbolic acid or other anti-septic or purifying medium, and causes
it to pass thence through a pipe, tube, or channel, which when the air is to be
charged with dry medicaments is provided with a hopper or receptacle arranged to
contain the medicament or medicaments and means for operating such hopper or
receptacle, so as to ensure the discharge therefrom into the pipe, tube, or channel,
through which the air rendered antiseptic, as aforesaid, passes from the fan or blower
of the requisite proportion of dry medicament.
Referring to the accompanying illustrative Drawings, Fig. 1 is a sectional side
elevation of apparatus for carrying out my Invention.
Fig. 2 is a plan also in section.
Fig. 3 is an elevation or end view.
Fig. 4 is a side elevation in section through the fan and air delivery tube.
A is a drum containing a coiled spring, which being wound up gives motion by a
chain or wire cord to the fusee B, and thence by a train of toothed wheels and
pinions C, C', and C², to a small fan D enclosed in a case E having a pipe El pro-
jecting from it with an inlet for the air at F. When required the air is warmed
as it enters, and this may be effected by means of a spirit lamp placed underneath
the inlet.
G is a diaphragm or screen of gauze properly saturated with carbolic acid or other
anti-septic or purifying medium to render the air passing through it anti-septic,
and fixed to the inlet branch of the fan case by an ivory ring or cap H which inter-
cepts the conduction of heat from E³.
The air drawn through the gauze by the fan D is forced along the delivery pipe J
(preferably of brass) into a flexible tube K fixed to the end of the pipe J and
terminating in a mouth piece for the patient.
The dry medicament is contained in a hopper or receptacle L which is closed by
a lid at top, and at bottom is perforated with a small hole. This hopper is able to
work freely in a case or guide formed upon the delivery pipe J, being supported by
a light spiral spring M upon which it rises and falls.
A small hammer N working upon a spindle O (having a spring coiled upon it) is
caused to strike successive blows upon the lid of the hopper L at regular intervals
by a tail lever P on the spindle O, which is alternately pressed down and liberated
by small studs fixed in the rim of the spur wheel C', the number of which studs
determines or regulates the intervals between the blows of the hammer N. At each
blow the hopper L is forced down upon the spring, and the concussion discharges a
small quantity of the dry medicament through the hole in the bottom of the hopper
into the centre of the current of air passing along the pipe J from the fan, and it is
carried forward mixed with the air into the mouth of the patient.

page_text: When the air is required only to be rendered antiseptic the hopper is not charged
with medicament, or the apparatus may for such purpose be constructed without
the hopper L, hammer N, and its operating gear, the operation of the fan blast and
other parts remaining the same. is a small cup designed to contain chloroform,
nitrate of amyl, or similar substances not required to be passed through the gauze
in cases where such applications may be necessary.
Having described the nature of my said Invention, and explained in what manner
the same is to be or may be performed or carried into practical effect, I hereby
declare that what I consider to be novel and original, and therefore claim as the
Invention secured to me under the Letters Patent hereinbefore in part recited
is,―
1. The method, substantially as hereinbefore described with reference to the
accompanying Drawings, of rendering air antiseptic and charging it with dry
medicaments for the purpose of respiration as a curative or palliative agent in
pulmonary or other affections.
2. The method, substantially as hereinbefore described with reference to the
accompanying Drawings, of rendering air in a room anti-septic without charging it
with dry medicament.
3. The improved apparatus constructed, arranged, and operating as described and
shewn for the purposes specified.
In witness whereof, I, the said Anthony Bell, have hereunto set my hand
and seal, this Nineteenth day of April, in the year of our Lord One
thousand eight hundred and eighty.
