An Improved Disinfecting and Deodorising Apparatus.
I, JOSEPH THOMAS FREESTONE, of 1 Kerfield Terrace, New Ferry in the County
of Chester, Chemist, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a disinfecting and deodorising apparatus in which the
disinfecting and deodorising is effected by slowly evaporating, by heat, a suitable
Hiquid containing eucalyptus, terebene or the like, the object being to provide a
simple and cheap apparatus in which an ordinary night light or fairy lamp may be
used as a source of heat and in which the liquid to be evaporated is supplied continu-
ously and automatically to an evaporating dish containing the disinfectant.
According to my invention I construct such apparatus as follows;-
The evaporating dish is carried by suitable supports some distance above the base
of the apparatus wbich is adapted to hold the night light or the fairy lamp, as the
case may be, and the heat from the latter heats the evaporating dish and slowly
evaporates the liquid therein. The liquid for replenishing the evaporating dish is
contained in a conical reservoir closed with the exception of an outlet at the apex
thereof; the evaporating dish is about half filled with the liquid, and the conical
reservoir is filled, then inverted and placed with the outlet in the liquid in the dish,
the outlet being closed by means of the finger until it is below the level of the
liquid in the dish. The reservoir is supported in this position, the outlet being of
course sealed by the liquid in the dish. The lamp is now lighted, and as the
disinfectant liquid in the dish is evaporated its level of course falls and as a result
the outlet of the reservoir is unsealed, air is thus allowed to enter and a corre-
sponding amount of disinfectant escapes and so replenishes the supply to the dish.
In this way a slow but continuous evaporation is ensured and an effective and
economical distribution of the disinfectant results; the night light or fairy lamp in
addition to supplying heat serves its usual purpose as an illuminant, so that the
apparatus is particularly useful in a sick room.

An Improved Disinfecting and Deodorising Apparatus.
I, JOSEPH THOMAS FREESTONE, formerly of i Kerfield Terrace, New Ferry in the
County of Chester, but now of 1 Alexandra Terrace, Bedford Road, Rock Ferry
in the County of Chester, Chemist, do hereby declare the nature of this inven-
tion 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 to a disinfecting and deodorising apparatus in which the
disinfecting and deodorising is effected by slowly evaporating, by heat, a suitable liquid

and cheap apparatus in which an ordinary night light or fairy lamp may be used
as a source of heat and in which the liquid to be evaporated is supplied continuously
and automatically to an evaporating dish containing the disinfectant.
According to my invention 1 construct such apparatus as follows;-
The evaporating dish is carried by suitable supports some distance above the base
of the apparatus which is adapted to hold the night light or the fairy lamp, as the case
may be, and the heat from the latter heats the evaporating dish and slowly evaporates
the liquid therein. The liquid for replenishing the evaporating dish is contained
in a conical reservoir closed with the exception of an outlet at the apex thereof; the
evaporating dish is about half filled with the liquid, and the conical reservoir is filled,
then inverted and placed with the outlet in the liquid in the dish, the outlet being
closed by means of the finger until it is below the level of the liquid in the dish.
The reservoir is supported in this position, the outlet being of course sealed by the liquid
in the dish. The lamp is now lighted, and as the disinfectant liquid in the dish is
evaporated, its level of course falls and as a result the outlet of the reservoir is unsealed,
air is thus allowed to enter and a corresponding amount of disinfectant escapes and so
replenishes the supply in the dish. In this way a slow but continuous evaporation
is ensured and an effective and economical distribution of the disinfectant results ;
the night light or fairy lamp in addition to supplying heat serves its usual
purpose as an illuminant, so that the apparatus is particularly useful in a sick
room.
I have illustrated my invention in the accompanying drawings, in which Fig. I is
an elevation in section on the line A. A., Fig. II an elevation, and Fig. III a plan
in section on the line B. B. Throughout the drawings the same parts are indicated
by the same reference figures.
1 is the evaporating dish which is supported by three uprights 2 carried from a
base 3; the base has a central depression in which a glass fairy lamp is placed. The
fairy lamp consists of three portions, a lower glass or cup 4, an inner container 5 to
hold the night-light 13, and a coloured glass shade 6. The conical reservoir 7,
which is preferably made of glass, is supported by a ring 8 carried by the
uprights 2.
The glass cup 4 is provided with ribs 9 which support the shade, and between
which air enters to support combustion.
I also find it convenient to supply a cork 10 with a wire handle 11 attached,
which can be used, instead of the finger, to close the mouth of the container when
it is inverted; the cork and handle are attached to the apparatus by a chain.
A series of holes 12 in the outer cylindrical part of the evaporating dish serve
as exits for the heated air.
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 ;-
1. The improved disinfecting and deodorising apparatus which consists of an
evaporating dish supported over a fairy lamp or other source of heat, and into
which a reservoir, containing the disinfectant or deodorising liquid, dips so that
its outlet is sealed by the liquid in the dish; substantially as described and
illustrated.
2. The improved disinfecting and deodorising apparatus, substantially as described
and illustrated in the drawings.
