Improvements in Apparatus for Volatilizing Medicaments, Disinfec-
tants and the like.
I, VINCENZO CERVELLO, of No. 38, Via Torremezza, Palermo, in the Kingdom
of Italy, Professor, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
The apparatus forming the subject of this invention is designed to impregnate
the air in living-rooms with vapours in definite proportions of such medicaments
disinfectants and the like as are capable of volatilizing either from the solid
or from the liquid state at a temperature not exceeding 100° C.
The capability of the apparatus to impregnate to any desired degree is due
to the medicaments being volatilized by contact with a surface heated by steam
at atmospheric pressure, that is at a practically constant temperature, so that
a definite quantity of a certain medicament develops a definite amount of vapour
within a certain definite time.
If the cubical capacity of a room has been ascertained it will be an easy
matter by the aid of this apparatus to distribute exactly the quantity required
of the volatilized medicament.
Furthermore the operation of the apparatus is such as to enable it to work
for several hours without any attention to it providing means are provided for
returning the steam, which heats the walls of the apparatus, in a condensed
form without allowing the condensation water to come into contact with the
medicaments requiring to be volatilized.
Referring to the accompanying drawing:
Figure shows a side elevation of one form of my apparatus.
Figure 2 is a plan thereof, and
Figure 3 is a longitudinal vertical section of the apparatus.
The casing a provided with a handle b is formed with air-holes g, h and with
a front opening f for the introduction of the spirit lamp c. The lamp is
arranged to burn for several hours and has two wicks or a duplex burner d and e
operated by spindles d* and a* and rack and pinion wheels.
The upper portion of the casing a contains the water boiler i, having a flat
top-plate j, which is heated from below. The top-plate j is formed with a

page_text: centrally arranged dome k closed at top by a rubber stopper l. Through the said
stopper a thin glass pipe m is introduced the lower end of which never dips
into the water of the boiler i and which extends upwards so far (to 60 cm. and
more) as to cause, as before mentioned, the steam to condense inside this pipe
and finally return into the boiler without wetting the outside of the pipe m.
The substance, or substances, to be vaporized, is, or are, placed upon the plate i
and is, or are, distributed in the various sectors o surrounding the dome and
limited by the ring n.
The apparatus is used in the following manner:
First the boiler is filled with water to about 8 to 9 tenths of its capacity
whereupon the stopper 7 is inserted into the opening of the dome & taking care
that the lower end of the pipe m does not descend into the water. Then the
ring n is placed around the domek and the proper quantity of the substance, or
substances for volatilization, is, or are, distributed over the plate j within the
sectors of the ring n.
The two wicks or burners d and e are then lit and allowed to burn until the
water is brought to boiling after which one of the flames is extinguished and
the other lowered so far as to keep the water just boiling until the substance or
substances are completely volatilized.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
An apparatus for volatilizing medicaments (disinfectants) in definite propor-
tions, characterized by the fact that the substance, or substances, for volatilization
is, or are, distributed upon a surface of a boiler heated by convenient means
and the contents of which pass as steam through a long vertical pipe where it
is condensed by the outer atmosphere and returns into the boiler without being
allowed to mix with the volatilized substance.
