PROVISIONAL SPECIFICATION.
Improved Means for Disinfecting, Deodorizing, or Perfuming
the Air.
1, MARTIN SAMUEL SHARP of Penge Villa, 25 Ashburton Road, Southsea, in
the County of Hampshire, late Captain The King's Own Royal Lancaster
Regiment, Military Train, and Reserve of Officers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improved means for disinfecting or deodorizing and
consists of an evaporating apparatus for continuously feeding (by atmospheric
pressure) a fibrous body contained in a suitable receptacle covered with a perforated
lid so as to ensure an automatic evaporation of any volatile liquid for disinfecting,
deodorizing, or perfuming the air. The apparatus I propose to employ is composed
of a bulb of glass or other suitable material for holding the liquid: this bulb
terminates in a cylindrical neck which latter reaches nearly down to a cupola
embossed in the centre of a saucer made of metal or other suitable material such
saucer having in its centre a circular convexity around the edge of which is
soldered a band of metal at the base of which one or two holes are made for the
ingress of air and the egress of the liquid contained in the aforesaid bulb. It is
into this band and almost touching the cupola that the mouth of the neck of the
bulb falls when the apparatus is closed or working.
The neck of the bulb is cemented into a metal tube, having a notch at its base,
and which is long enough to touch the bottom of the saucer; and it is soldered
round its upper rim to a convex metal plate (having a round hole in its centre)
which serves as a cover to the saucer. This cover is perforated and is attached to
the upper rim of the saucer by a hinge, and is kept closed either by a deflection of
the opposite part of the rim of the cover, or by a tongue of metal acting as a
spring and cut from the handle which is soldered to the upper and lower rims of
the saucer. The cover when opening or shutting moves the bulb with it. There
may be an inner perforated cover fitting close to the outer one and revolving round
the tube so as to partially or completely close the perforations in the outer one,
and moved by means of two little knobs on the edge of the inner one, and
protruding through slots on the edge of the outer cover so as to modify the
evaporation. At the bottom of the saucer is placed a piece of lamp wick or other
fibrous substance so as to surround the aforesaid circular band in the centre of the
saucer and which fibrous material is fed (by atmospheric pressure) with liquid from
the said bulb, the neck of which may be corked for travelling. The apparatus
without a handle may be screwed to a bracket or with a handle may be fixed to a
frame to hold the roll of paper for w.c's.
In order to catch any drops resulting from a too rapid evaporation or "sweating,"
a piece of woollen cloth may be stuck to the bottom of the saucer outside, or a
second plate with turned up rim may be attached thereto.

the Air.
I MARTIN SAMUEL SHARP, of Penge Villa, 25 Ashburton Road, Southsea in
the County of Hampshire, late Captain The King's Own Royal Lancaster
Regiment, Military Train and Reserve of Officers, do hereby declare the nature of
this invention and in what mauner the same is to be performed to be particularly
<described and ascertained in and by the following statement :—
This invention relates to improved means for disinfecting, deodorising or
perfuming the air, and consists of an evaporating apparatus continually feeding a
fibrous body contained in a suitable vessel covered with a perforated lid so as to
ensure an automatic evaporation of any volatile liquid for disinfecting, deodorising
or perfuming the air.
The apparatus I propose to employ is composed of a vessel terminating with a
.neck, which latter reaches nearly down to a cupola embossed in the centre of a
saucer made of metal or other suitable material, such saucer having in its centre
a circular convexity around the edge of which is soldered a band of metal, at the
base of which latter one or two holes are made, for the ingress of air and the egress
of liquid contained in the aforesaid vessel. It is into this band, and almost touching
the aforesaid cupola, that the mouth of the neck of the vessel falls when the
apparatus is closed or working.
The neck of the vessel is cemented into a metal tube having a notch at its base,
which is long enough to touch the bottom of the saucer and is soldered round its
upper rim to a convex metal plate (having a round hole in its centre) which serves
as a cover for the saucer. This cover is perforated and is attached to the upper
rim of the saucer by a hinge, and this cover is kept closed by a suitable fastening.
The cover when opening or shutting moves the aforesaid vessel with it.
There may be an inner perforated cover fitting close to the outer one, and
revolving round the tube, so as to partially or completely close the perforations in
the outer one, and moved by means of two little knobs on the edge of the inner
cover, such knobs protruding through slots in the outer cover; this arrangement
being intended to modify the evaporation.
In the inside of the saucer is placed a lamp-wick or other fibrous substance, so as
.to surround the aforesaid circular band, in the centre of the saucer, which fibrous
material is fed with the liquid from the said vessel.
The neck of the vessel may be corked for travelling.
In order that my said invention may be more clearly understood, I will now
proceed to describe the same with reference to the accompanying sheet of drawings
in which Fig. 1 shews front elevation of an appliance constructed according to this
invention Fig. 2 section through line A B Fig. 1.
The same letters denote the same parts in both the views.
a shews a hollow ball, made preferably of glass, provided with a neck b, c shews
'a shallow vessel or saucer, on to which is hinged a cover d, perforated with small
.boles as shewn in Fig. 1. To the under side of the said cover, a tube e is soldered,
at the bottom of which are one or more notches n. Into this tube the neck bis
cemented. A portion of the bottom of the vessel c is made convex as shewn at f,
and round this convex portion f is soldered a band of metal g, provided with a
hole; shews an upright piece of metal or other suitable material, to fix the
appliance against the wall or other surface; k shews a spring tongue, to lock the
cover b in position when closed, as shewn at Fig. 2, but of course any other suitable
fastening might be used for this purpose.

page_text: The dotted lines at Fig. 2 shew the cover d as it would appear when opened,
ready to charge the ball a with fluid, shews a piece of cotton wick or other
absorbent material, placed at the bottom of the vessel e.
Instead of having a ball a, as shewn, it is obvious that I may have a reservoir of
other form. I may also have more than one hole in the metal band h.
The action is as follows:-
Having charged the reservoir a, when in the position shewn in dotted lines at
Fig. 2 with the desired fluid, I then close the appliance, as represented at Figs. I
and 2, and after a short time the fluid will slowly evaporate from the wick 4,
through the perforations in the cover d and become diffused into the atmosphere,
thus deodorising, disinfecting or perfuming the apartment in which the appliance is
placed, the wick being continually supplied with fresh liquid until the reservoir a
is exhausted.
I may if found desirable place a second perforated cover, capable of revolving,
fitting close to the outer one, so that the former may be turned round in order to
partially or completely cover the perforations of the latter, so as to prevent too
rapid diffusion of the fluid.
In order to catch any drops resulting from a too rapid evaporation or sweating,
a piece of woollen cloth m may be stuck to the bottom of the saucer c, or a second
plate with turned up rim may be attached thereto.
The above described appliance will be found particularly suitable for hanging in
water-closets and like places; also in hospitals for disinfecting or deodorising the
air; or when charged with perfumes will be found suitable for hanging in drawing-
rooms or other apartments for perfuming the air, as an appliance made as above
described may be made very ornamental for this purpose.
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. The improved means for disinfecting, deodorising or perfuming the air
substantially as hereinbefore described and represented on the accompanying sheet
of drawings.
2. In means for disinfecting, deodorising or perfuming the air: an inverted
reservoir, in combination with a neck, extending into a band of metal, having a
hole or holes therein, fitted into the bottom of a vessel, provided with a perforated
cover; such vessel being furnished with a wick or other absorbent material; all
substantially as and for the purposes set forth.
