Improvements in Vaporizers.
I, HARRY DE BACON PAGE, of Chatham, in the County of Morris, State of New
Jersey, United States of America, Manufacturer, do hereby declare the nature of
this 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 relates generally to vaporizers or censers used for vaporizing
or evaporating medicinal substances, perfumes, incense and similar substances
and relates particularly to the form of vaporizers more specially designed for
vaporizing cresylic acid, or vapo-cresolene" in a sick room for the treatment of
diseases of a zymodic character, such as diphtheria, whooping cough, asthma and
other similar diseases.
The object of my invention is to provide a construction which will accomplish
all the results made possible by previous vaporizers but in a more satisfactory
manner, and yet which will be cheaper, simpler and more durable.
I attain this object by the mechanism illustrated in the accompanying
drawings in which
Fig. 1 is a side elevation of my improved vaporizer, the upper portion of which
is in mid section.
Fig. 2 is a side elevation of the vessel E, and of the bell G with the perforated
and threaded thimble H.
Referring to Figs. 1 and 2, the ring shaped base or foot A, the upright frame
or standard B, and the lamp C which fits into the base A, may be constructed in
any suitable or convenient manner; or other well known devices may be used
for holding the cup or basin and the vessel over the flame or source of heat.
1) is a cup or basin in which the liquid to be vaporized is placed. This basin
is set on the top of an open vessel having raised sides or edges a so that when
the vessel D) is placed thereon an air chamber F is formed beneath it within the
vessel E. The edges of the basin are turned slightly down at in order to fit
over the edges a of the vessel E and retain the basin in place thereon. The
bottom of the vessel E is formed with an opening c, preferably in the center.
The sides of the vessel E are drawn down below this opening so as to form a
short tube or throat e which is threaded as at e¹ to correspond with the threads
on the thimble hereafter described. The sides of the vessel are perforated at
intervals with small openings d d for the escape of gases from the air chamber F.
G is a metal bell the top of which is spun or pressed into a closed tube or
thimble, which corresponds in size to the inner diameter of the open tube or
throat e of the vessel E. Near the top of this thimble are a number of perfora-
tions and below the perforations and between the perforations and the bell the
outer walls of the thimble are threaded as shown at h¹ to correspond with the
threads on the inner walls of the throat e of the vessel E. The bell G and
the vessel E are then put together by screwing the tube e upon the thimble H,
first passing the said thimble H through the ring of the standard B where a
ring is used for supporting the vessel E and the basin D). Instead of being
threaded the tube e may be made with corrugations and the thimble H with

page_text: corresponding corrugations so that when the thimble is pressed into the tube the
corrugations on the thimble will spring into the corrugations on the tube and
thus securely fasten the two parts together. When the lamp C which stands
directly beneath the bell G is lighted, the heat passes upward from it through
the bell and the thimble and through the perforations H into the chamber F.
On entering this chamber the gases flow in diverging directions through the outer
wall of the chamber where they pass through the openings d d. The bell G,
the chamber F and the openings d d together form a flue through which the
heat from the flame is drawn and is evenly distributed over the entire under
surface of the basin D, thus insuring the heating of the entire surface of the
basin at a steady and even heat and preventing the heating of one part to a
temperature greater than the other parts.
The bell and the vessel of my improved form of vaporizer can be easily joined
by the manufacturer or the purchaser by screwing or pressing them together by
hand. When the parts are thus joined there is no danger of the thimble loosen-
ing and becoming lost. I also find that the construction of my vaporizer
involves less labor, material and expense than other forms of vaporizers which
have been used. Other advantages will readily suggest themselves to persons
familiar with the old forms of vaporizers.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is:-
A vaporizer consisting of the combination of the basin as 1), for contain-
ing the substance to be vaporized; a cup shaped vessel, as E, adapted to support
the basin and deep enough to form an air chamber beneath it and having its
walls prolonged into an open tube, as e, around an opening, as c, in its bottom,
and having the walls of said tube threaded; a bell, as G, arranged beneath said
vessel and having a thimble, as H, extending upward therefrom, the walls of said
thimble being perforated near the top and being threaded between the perfora-
tions and the bell to correspond with the threads on the tube e; and a frame or
standard adapted to uphold the vessel E and bell G above a source of heat, sub-
stantially as and to the effect set forth.
A vaporizer consisting of the combination of the basin, as D, for containing
the substance to be vaporized; a cup shaped vessel, E, adapted to support the
basin and deep enough to form an air chamber beneath it and having its walls
prolonged into an open tube, as e, around an opening, as c, in its bottom, and
having the walls of said tube corrugated: a bell, as G, arranged beneath said vessel
and having a thimble, as H, extending upward therefrom, the walls of said thimble
being perforated near the top and having corrugations between the perforations
and the bell to correspond with the corrugations on the tube e; and a frame or
standard adapted to uphold the vessel E and bell G above a source of heat, sub-
stantially as and to the effect set forth.
