PROVISIONAL SPECIFICATION.
An Appliance for Scenting, Deodorising, and Disinfecting Rooms
and other Places.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Analytical Chemist, of
96 Amhurst Park, Stamford Hill, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
In Specification of my Patent No. 6249 of 1891 I have described an appliance
for automatically purifying or scenting the air of dwelling rooms and other
apartments and destroying unpleasant smells and my present invention is in
connection with the same subject.
I use a block of an absorbent material such as plaster of paris for soaking up
the perfume or volatile disinfectant or other purifying liquid and I provide a
cavity in the block of a size to contain a suitable measure of the liquid thus
dispensing with the necessity of using a separate reservoir for the disinfectant
or other fluid and any other means of charging the block. It is of advantage,
whatever material is used, to first of all thoroughly dry it by the application
of heat.
The shape that I prefer is a long cylindrical block with a cavity extending from
about the centre to the top surface.
In charging the absorbent block this cavity should be filled with the perfume
or disinfectant or other agent and in due time the whole of it is soaked up. The
cavity is to be refilled from time to time as found necessary.
Such a contrivance as I have described automatically gives off the vapour of
the agent with which it is charged and the surrounding atmosphere is thus
perfumed, disinfected, or purified.
The porous block thus charged may be suspended in any convenient position
where the air can obtain free access to it and for this purpose it may be provided
with an eye or it may be held in a frame or cage.
Dated this 1st day of January 1892.

COMPLETE SPECIFICATION.
An Appliance for Scenting, Deodorising, and Disinfecting Rooms
and other Places.
I,, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Analytical Chemist, of
96 Amhurst Park, Stamford Hill, in the County of Middlesex, 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 :-
In Specification of my Patent No. 6249 of 1891 I have described an appliance
for automatically purifying or scenting the air of dwelling rooms and other
apartments and destroying unpleasant smells and my present invention is in
connection with the same subject.
I use a block of an absorbent material such as plaster of paris for soaking up the
perfume or volatile disinfectant or other purifying liquid and I provide a cavity in
the block of a size to contain a suitable measure of the liquid thus dispensing with
the necessity of using a separate reservoir for the disinfectant or other fluid and
any other means of charging the block. It is of advantage, whatever material is
used, to first of all thoroughly dry it by the application of heat.
The shape that I prefer is a long cylindrical block with a cavity extending from
about the centre to the top surface.

page_text: In charging the absorbent block this cavity should be filled with the perfume or
disinfectant or other agent and in due time the whole of it is soaked up. The
cavity is to be refilled from time to time as found necessary.
Such a contrivance as I have described automatically gives off the vapour of the
agent with which it is charged and the surrounding atmosphere is thus perfumed,
disinfected, or purified.
The porous block thus charged may be suspended in any convenient position
where the air can obtain free access to it and for this purpose it may be provided
with an eye or it may be held in a frame or cage.
The block as above stated may be of plaster of paris, or instead of using plaster
of paris to make the absorbent block a variety of materials may be used as for
examples, a mixture of plaster and sawdust, or a mixture of plaster and coke, and
before charging with the disinfectant or perfume, the blocks may be burnt if
desired in order to render them more absorbent.
Among other materials that may usefully be employed are magnesia and
carbonate of magnesia pressed into blocks of suitable shape and size. They are
extremely absorptive and very suitable for use with such disinfecting substances as
sanitas oil which are not wholly volatile and also undergo further oxidation when
exposed to the air.
A block measuring about 4 inches in height, 1 inches in diameter and with a
cavity holding about 10 cubic centimetres, is convenient for use but of course
both the size and shape as also the capacity of the cavity may vary within wide
limits.
The blocks may be charged at first either by repeatedly filling the cavities with
the perfume or disinfectant to be used or they may be immersed in the same liquids
until they are saturated therewith. Or, again, they can be charged only to &
limited extent at first and be further charged from time to time for example once a
week by filling the cavities with the perfume or disinfectant.
As illustrating the absorptive capacity of various blocks I may state that I have
ascertained that a block of plaster and sawdust in equal proportions by volume and
weighing about 100 grms. after burning will readily soak up more than 58 grms. of
oil of eucalpytus. A magnesia block weighing 46 grms. will readily soak up more
than 100 grms. of sanitas oil and a block of plaster and sawdust (unburnt) weighing
about 140 grms. will readily soak up about 50 grms. of sanitas oil.
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 :-
Blocks of absorbent materials provided with cavities for charging or recharging
same with liquid perfumes, disinfectants or air purifiers for the purpose of auto-
matically purifying or scenting the air and destroying unpleasant smells.
