WILLIAM HENRY MURRAY Chemist Assistant 15 Mayfield Villas Merton Road
Wandsworth Surrey and THOMAS JAMES KINSLEY, Gentleman of 108, Gaisford
Street, Kentish Town, in the County of Middlesex do hereby declare the nature of
this invention to be as follows:-
An apparatus, "which is to be used for the purpose of vaporising" medicinal,
disinfectant, perfuming and other substances consisting of a double metal cone
connected at its base.
In the enclosure formed by the inner and outer metal cones it is proposed to
use a heat producing power.
-
The inner cone is to be made of a heat conducting metal, and hollow, so as to
contain the flask or bottle holding the substance to be vapourised; and will terminate
at a certain height above the outer cone.
The outer cone is to be made of a non-heat conducting metal.
The heat used may be either gas, oil or spirits of wine.

COMPLETE SPECIFICATION.
An Improved Apparatus for Vapourizing Medicines, Disinfectants,
Perfumes, and other Substances.
We WILLIAM HENRY MURRAY of 15 Mayfield Villas Merton Road Wandsworth in
the County of Surrey Chemists Assistant and THOMAS JAMES KINSLEY of 108
Gaisford Street Kentish Town London Gentleman 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 consists of an apparatus or contrivance for vapourizing by heat
(such as from the flame of a gas or other suitable burner or lamp-for instance a
spirit lamp) any suitable medicines chemicals or chemical compounds for medicinal
purposes or otherwise such as disinfectants and perfumes etcetera or for vaporizing
or burning any other substances or materials as desired (for instance insect destroyers
microbe killers etcetera etcetera) and for which it may be suitable.
The chemicals or ingredients are contained in a kind of flask or holder of any
suitable material (but advantageously made of glass) and this holder or vessel is
placed in the centre part of the apparatus or contrivance which forms the subject
matter of the present invention and which we will now proceed to fully describe with
reference to the accompanying sheet of drawings-so that the said invention may be
fully understood and readily carried into practice.
Figure 1 represents a side view in elevation of the said apparatus or contrivance
and heated by a gas jet on the well known "Bunsen" burner principle.
Figure 2 is a vertical central section of Figure 1.
Figure 3 is a plan of Figure 1 with the double shield or cover removed.
Figure 4 is a similar apparatus only heated by a spirit lamp instead of by a gas jet
as in Figures 1 to 3.
a is the bottom or supporting frame mounted on legs a¹ and carrying the gas pipe b
the turned up end 6' of which forms the burner.
Upon this frame a is placed the flask c or other convenient vessel which contains
the chemicals or ingredients to be vapourized and over this flask c is placed the double
Pring f21

page_text: casing d and e the inner part d of which completely covers the flask or vessel c.
and forming an annular space between said inner case d and the outer wall e
and top e¹.
The burner or heat producer is mounted in this annular space x between the inner
casing d and the outer casing e-and air to support combustion is admitted through
suitable openings below while the products of combustion can escape through suitable
openings and f¹ in the casing or outer wall e these holes fand f¹ being of such a
size that a warm body of air is retained in the space x.
The flame from the burner thus produces a constant heat (subject to regulation)
around the flask or chemical holder c and so vapourizes the contents which pass
out up the passage or chimney d¹ into the room or compartment in which the apparatus
is in use.
Figure shows an equivalent apparatus only the heat producer in this case is a
spirit lamp the reservoir or vessel g for holding the spirits forming the base or stand
upon which legs a' of the apparatus are mounted.
All the other parts are identical or equivalent to those previously described.
It will be obvious that the apparatus may be made any size and proportions
or dimensions according to requirements and any suitable material or materials
may be used in the construction thereof-though it may be mentioned that brass
or copper will be found very advantageous for forming the parts d d¹ and e e¹
which latter may be formed all in one part as shown or in separate parts if
desired.
The form or shape of the apparatus may also be varied if desired.
The arrangement of the shield or wall d between the burner or heat producer
and the vessel c containing the chemicals etcetera is of great importance and forms
an essential feature of our present invention.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. An apparatus for vapourizing chemical or other ingredients having a double
metal covering or hood substantially as and for the purposes hereinbefore described
and illustrated in the drawings annexed.
2. An apparatus for vapourizing chemical or other ingredients in which a gas or
other suitable burner or heat producer is arranged and acts in the space formed
between the inner and outer walls of a double cover or hood-the vessel containing
the ingredients etcetera to be vapourized being within the inner wall and thus
having a wall or covering interposed between same and the burner or heat
producer.
3. In an apparatus for vapourizing chemical or other ingredients-the com-
bination of a gas or other burner or heat producer with a double cover or hood
substantially in the manner and for the purposes herein before set forth.
4. An apparatus for vapourizing chemical or other ingredients in which the vessel
containing said chemicals etcetera has a complete shield or cover interposed between
same and the flame from the gas burner or other heat producer substantially in the
manner and for the purposes hereinbefore set forth.
