PROVISIONAL SPECIFICATION.
An Improved Vaporizing Apparatus for Vaporizing Medicinal
Compounds and the like.
I, ARTHUR MARSHALL CHAMBERS, of Thorncliffe, in the County of York, Colliery
Proprietor, do hereby declare the nature of this invention to be as follows:
-
This invention relates to a new or improved apparatus by which liquid or other
substances can be kept at about a uniformn temperature, so that they are vaporized
regularly and equally, and the speed of such vaporization can be regulated so
that it is more or less rapid, as may be desired.
The apparatus is more especially applicable to the gradual vaporization of
medicated liquids or compounds in cases of asthma or the like diseases, the
curative vapour being gradually and uniformly disseminated through the air
which the patient has to breathe, and the operation being continued gradually
and automatically by night as well as by day.
In order to put my invention in operation, I take a base, of tin plate or other
suitable metal or material, preferably circular in plan.
In the centre of this base I make a circular opening, into which fits freely a
circular depressed holder or receiver-preferably stamped up from tin plate or
other sheet metal, and having at one side a ring or handle by which it can be

size as to receive freely the lower end of a candle of a kind such as are well known
and largely used as "Pyramid Night-lights," which when once lighted are capable
of giving, without attention, a steady flame for many hours.
Upon the outer circumference of the base described, I form or attach a vertical
cylinder, also preferably of tin plate, which surrounds the light described, except
on one side which is open for a sufficient height for the purpose of introducing and
removing the holder containing the light; and at the back of the cylinder I make
or attach a handle by which the entire apparatus can be easily and conveniently
carried about.
Round the upper part of the vertical cylinder, above the opening at its side, I
make a series of openings, preferably in the form of vertical slits,-at equal
distances apart, and round them I fit a second outer cylinder having similar open-
ings, which can be turned round upon the inner cylinder, so that the openings
through both coincide, or so that they are closed, the moveable outer cylinder
acting as a regulator.
In the upper open end of the main cylinder I fit a dish or receptacle for the sub-
stance or substances to be heated and vaporized. This is made in the shape of a hollow
bowl or basin of sufficient depth, a flange or rim round its upper edge fitting upon
and being supported by the upper edge of the main cylinder.
The bowl may be made of any suitable material, but I preferably make it of
copper of such thickness-especially at the bottom-that the heat from the candle
below only passes through it sufficiently readily to keep the contents at just
the required temperature for their slow and uniform vaporization.

page_text: When the apparatus is to be used, the substance to be vaporized is placed in
the copper bowl, and the holder having the lighted candle fitted into is is placed
in the recess in the base. The bowl is thus heated and kept hot, and the intensity
of the heat can be regulated and varied by suitable adjustment of the perforated
outer cylinder, by means of which more or less of the heated air can be allowed
to pass out.
The apparatus is very simple, cheap, portable, and easily used, and it is very
effective for the purpose required.
An Improved Vaporizing Apparatus for Vaporizing Medicinal
Compounds and the like.
I, ARTHUR MARSHALL CHAMBERS, of Thorncliffe, in the County of York, Colliery.
Proprietor, 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, and accompanying drawing, that is to say:-
This invention relates to a new or improved apparatus by which liquid or other
substances can be kept at about a uniform temperature, so that they are vaporized
regularly and equally, and the speed of such vaporization can be regulated so
that it is more or less rapid, as may be desired.
The apparatus is more especially applicable to the gradual vaporization of
disinfecting substances, or of medicated liquids or compounds in cases of asthma
or the like diseases, the curative vapour being gradually and uniformly dis-
seminated through the air which the patient has to breathe, and the operation
being continued gradually and automatically by night as well as by day.
The accompanying drawing is in illustration of my invention. Figure 1 is
a side view, and Figure 2 a front view of the apparatus. Figure 3 is a section of
the evaporating dish, and Figures 4 and 5 are a plan and side view of the candle
holder.
In order to put my invention in operation, I take a base a, of tin plate or other
suitable metal or material, preferably circular in plan.
In the centre of this base I make a circular opening, into which fits freely
a circular depressed holder or receiver 6-preferably stamped up from tin plate
or other sheet metal, and having at one side a ring or handle c by which it can
be readily lifted in or out of the opening in which it fits. This holder is of such
a size as to receive freely the lower end of a candle d of a kind such as are well-
known and largely used as "Pyramid Night-lights," which when once lighted are
capable of giving, without attention, a steady flame for many hours.
Upon the outer circumference of the base a described, I form or attach a vertical
cylinder e, also preferably of tin plate, which surrounds the light described, except
on one side which is open for a sufficient height for the purpose of introducing
and removing the holder containing the light; and at the back of the cylinder
I make or attach a handle g by which the entire apparatus can be easily and
conveniently carried about.
Round the upper part of the vertical cylinder, above the opening at its side,
I make a series of openings, preferably in the form of vertical slits,--at equal
distances apart, and round them I fit a second outer cylinder h having similar

page_text: openings i, which can be turned round upon the inner cylinder e, by means of
a stud or handle k, so that the openings through both coincide, or so that they
are closed, the moveable outer cylinder h acting as a regulator.
In the upper open end of the main cylinder I fit a dish or receptacle / for the
substance or substances to be heated, and vaporized. This is made in the shape of
a hollow bowl or basin of sufficient depth, a flange or rim m round its upper edge
fitting upon and being supported by the upper edge of the main cylinder.
The bowl may be made of any suitable material, but I preferably make it of
copper of such thickness-especially at the bottom, as shown in Figure 3-that
the heat from the candle below only passes through it sufficiently readily to keep
the contents at just the required temperature for their slow and uniform vaporiza-
tion.
When the apparatus is to be used, the substance to be vaporized is placed in
the copper bowl, and the holder having the lighted candle fitted into it is placed
in the recess in the base. The bowl is thus heated and kept hot, and the
intensity of the heat can be regulated and varied by suitable adjustment of the
perforated outer cylinder, by means of which more or less of the heated air can
be allowed to pass out.
The apparatus is very simple, cheap, portable, and easily used, and it is very
convenient and effective for the purpose required.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The apparatus for vaporizing, and disseminating the vapour of, medicinal or
disinfecting liquids, consisting of recessed base a, chamber e having lateral open-
ing f and openings i regulated by adjustable cover h, moveable dish for the liquid,
supported on chamber e, and moveable holder b fitting in base a and carrying
candle d, the flame from which transmits an easily regulated and continuous
heat to the contents of the dish as described and shown.
