COMPLETE SPECIFICATION.
An Appliance for Automatically Purifying or Scenting the Air
of Dwelling Rooms and other Apartments, and Destroying
Unpleasant Smells.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Past Vice President of the
Society of Public Analysts, 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 :-
According to this invention I use an absorbent material such as saw-dust, flour,
kieselguhr, magnesia, sand, chalk, cotton wool, cotton waste &c., for soaking up a
large quantity of a perfume or volatile disinfecting or purifying agent such as
"sanitas oil and I enclose the same in a suitable envelope constructed so that
the volatile emanations may have free access into the surrounding air. I form
the envelope of wire gauze and preferably employ two such envelopes the one
inside the other, there being an annular space between the two, so that if any of
the "sanitas oil or other volatile agent should by any chance condense on or
otherwise obtain access to the outside surface of the inner envelope it cannot
come into contact with the outer envelope which is thus preserved clean and free
from stickiness.
The absorbent material impregnated with the active agent may be placed loose
in the inner envelope or it may preferably be first of all incased in a bag of
muslin, gauze, or other suitable material, and the bag be then placed in the
envelope or cage of wire gauze or other suitable perforated material. The cage
thus prepared may be soldered or otherwise attached at one end to a stand or
tray having a handle or flange so that it may be placed upon tables &c. or the
apparatus may be fitted with eyes or other attachments by means of which it may
be affixed to the doors or walls of rooms &c.
The cage may be open at the upper end or be fitted with a perforated lid.
It is obvious that the shape or form as also the material of the apparatus may
be considerably varied and I give a drawing of one convenient form with a
description of its several parts.
Figure is an elevation, Figure 2 a vertical section and Figure 3 a plan of the
apparatus.
A is the tray or base A' a flange around the edge of the tray which serves as
a handle. Ban upright cylinder of wire gauze secured at its lower end to the
tray. C, an inner cylinder of wire gauze also secured to the tray. D a perforated
lid covering the top of the outer cylinder B.
EE are eyes by which the apparatus may be affixed to a door or wall. F is a
bag of muslin or other openwork fabric containing absorbent material impregnated
with the perfume or purifying agent.
If sawdust be employed as the absorbent material it can be caused to take up
or absorb so much "sanitas oil riz. more than its own weight so that it will
remain effective for many months but in order to renew the efficiency when
desired or necessary, the lid on the top of the cage may be temporarily removed
and a further quantity of sanitas oil "be introduced into the absorbent material
by means of a syringe or pipette or otherwise.
It is obvious that any perfume or any chemical agent that is compatible with the
absorbent material may be used in the way I have described but for purifying
the air I prefer to employ "sanitas oil because it is sufficiently volatile and
its vapour, in contact with hygroscopic moisture, gives rise to the formation of

page_text: peroxide of hydrogen (a very active oxidising agent) at the same time that the
air is rendered aseptic.
The apparatus may be used to advantage not only in dwelling rooms, lavatories,
closets, cellars, hospitals and sick rooms but also for the treatment of asthma and
those lung and throat affections in which advantage is known to be conferred by
a so-called pine treatment. "Sanitas oil" represents the active principles which
are generated naturally in a pine forest and by placing such an apparatus
as I have described in a room, the air is kept charged with the same volatile
principles.
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
"
1. An appliance for automatically purifying or scenting the air of dwelling
rooms and other apartments and destroying unpleasant smells such appliance
consisting of saw dust or other absorbent material impregnated with "sanitas oil
or other volatile purifying or perfuming agents contained within a casing or
recptacle of wire gauze or other suitable perforated material which is surrounded
by an outer perforated casing with an air space between the casings substantially as
described.
2. The combination of the base or stand the outer cylinder of wire gauze rising
up therefrom and the inner cylinder for containing saw dust or other porous
material impregnated with sanitas oil or other volatile purifying or perfuming
agents.
