I, CARL GUSTAV WENDSCHUCH, of 11, Struvestrasse, Dresden, Germany, Mer-
chant, do hereby declare the nature of this invention to be as follows:-
The present invention relates to a disinfecting apparatus for apartments and
other places and it has especially for its object the construction of a regulatable
disinfecting apparatus provided with a cylinder composed of the disinfecting
material itself and in which a slow evaporation is provoked by means of an
exciting liquid.
The apparatus consists of a vessel made of glass, porcelain, or other analogous
This
material which is cylindrical at both ends and barrel shaped at the centre.
vessel can be secured to a plate capable of being hung upon the wall and which
has two metallic bands, capable of embracing the vessel above and below its
central swollen out or barrel shaped part, screwed or nailed to it at each side.
The vessel is closed at its lower end, whilst, at its upper end, it is provided,
round its circumference, with small openings of oval form; a cover having a button
or knob on top covers the vessel and this cover is pierced with holes of the same
shape as the openings in the vessel. The cover can be turned round, at will, to
such an extent as to wholly or partially open or close the openings in the vessel.
In the vessel is placed a cylinder having its material prepared with a solution
consisting of formaldehyde and which contains some ozonated wadding; it gives
off, in the air, some watery vapours of formaldehyde which are produced slowly
at the ordinary temperature but more rapidly when this temperature is increased
by the action of an aromatic and antiseptic exciting liquid called "ozonine"
placed upon the wadding of the cylinder aforesaid.
At the bottom of the elongated openings cut in the vessel at its upper end and
which can be opened and closed at will so as to produce a more or less powerful
disinfection, the vessel is made with openings which serve to liberate slowly the
vapours of formaldehyde which form continually in the interior of the
apparatus provided with the exciting liquid, thereby producing a
manent disinfection of less intensity and at the same time preventing the
apparatus charging itself to a dangerous extent with vapours.
per-
For suppressing the characteristic odour of the vapours of formaldehyde the
exciting liquid employed consists essentially of an aromatic liquid rich in ozone
and called ozonine.

An improveu Regulatable Disinfecting Apparatus.
I, CARL GUSTAV WENDSCHIUCHI, of 11, Struvestrasse, Dresden, Germany, Mer-
chant, 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:-
The present invention relates to a disinfecting apparatus for disinfecting and
purifying the atmosphere in rooms, offices, workshops, hospitals, closets, and
other places and it has especially for its object the construction of a regulatable
disinfecting apparatus, provided with a cylinder composed of the disinfecting
material itself, in which a constant but slow generation of gas is provoked by
means of an exciting liquid.
And in order that my said invention may be more readily understood and
carried into effect or practice, reference is made to the accompanying sheet of
drawings whereon:-
Fig. 1 shows the improved apparatus complete and ready for use.
Fig. 2 is a view of the disinfectant holding vessel or receptacle of the apparatus.
Fig. 3 shows the removable cover for said receptacle, and
Fig. 4 is a view of the cylindrical deodorizer.
On the drawings like reference letters refer to like parts throughout all the
figures. The letter A designates a substantially cylindrical receptacle, B indicates
the cover therefor; C and C₁ are thin metal bands for securing the receptacle A
to a board D or the like and E represents the deodorizer proper.
The improved apparatus is composed of a receptacle A preferably made of glass
or china and the central part of which is bulged as shown. The outer surface of
said receptacle is preferably provided with ribs a a and a¹, a¹, above and below
said bulge, said ribs forming grooves between them to hold the attaching metal
bands C and C¹, for securing the receptacle to a small board D or its equivalent
which may be hooked to the wall of the room or elsewhere as desired.
receptacle A has a series of circular openings G, for the purpose hereinafter de-
scribed, and above said openings G, there is another series of elongated openings
or windows F.
The
The cover B for said receptacle has a corresponding number of similar win-
dows F adapted to register with windows F or to shut the latter more or less
as may be required by the more or less purified state of the atmosphere.
The cylinder E, the material of which consists of wood wool, filaments of plants
or such like mixed with concentrated formic aldehyde and which is filled up with
wadding to receive the exciting fluid evolves wet formaldehyde vapours into the
atmosphere, said vapours being slowly produced at ordinary temperature but
more rapidly when this temperature is increased, by the action of the aromatic
and antiseptic exciting liquid called " ozonine "and which, as already stated, is
placed upon the wadding inserted in the cylinder E. This
" ozonine is com-
posed of fir-wood oil, eucalytus oil, sapool (mixture of tar and carburetted hydrogen)
and turpentine oil.
The foregoing apparatus, termed the "International Room-deodorizer" is
intended to deodorize or to disinfect and to purify the atmosphere within the
rooms, which result is obtained by the evaporation of cylinder E, inserted in the
glass or china receptacle A.
For producing a more or less efficient disinfection I have but to turn the
cover B of the receptacle A in order to cause the windows F¹ to register more or
less perfectly with the windows F, while the openings G provide for a slow
evolution of the formaldehyde gases, constantly produced within the apparatus, as

page_text: it is charged with the exciting fluid, whereby a continuous disinfection is pro-
duced and the apparatus prevented from being filled with an excessive charge
of gases.
The ozonine neutralizes the characteristic odours of the formaldhyde vapours.
The apparatus may be constructed and the various parts thereof arranged as
shown on the accompanying drawings but it is to be understood that any suitable
construction and arrangement of the parts may be adopted without departing from
the scope of the invention. I therefore do not confine myself to the precise form
of the apparatus shown, so long as the peculiar features of the invention be
retained.
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 consider novel and desire to claim is:--
1. In a regulatable disinfecting apparatus, the combination with a suitable
receptacle having a plurality of windows at its upper part of a removable cover
for said receptacle having a corresponding number of windows a suitably shaped
disinfecting substance inserted into said receptacle and means for causing the
said substance to evolve disinfecting gases, substantially as set forth.
2. In a disinfecting apparatus of the class described, the combination with a
substantially cylindrical receptacle having a central bulge and a plurality of win-
dows at its upper part of a removable cover for said receptacle having a corre-
sponding number of windows adapted to register with the former or to shut the
same, a disinfecting substance of cylindrical shape inserted into said receptacle, a
wadding inserted into the interior of the disinfecting substance after being
sprinkled with an exciting aromatic and antiseptic liquid for promoting the
evolution of disinfecting gases from said substance and means for permitting a con-
stant flow of the gases into the atmosphere and preventing the apparatus being
overcharged with the gases, substantially as set forth.
3. In a disinfecting or deodorizing apparatus, the combination with a sheath
or lining made of a disinfecting substance, of wadding or the like inserted into
said sheath and sprinkled with an aromatic and antiseptic fluid adapted to cause
disinfecting gases to evolve from said sheath, substantially as and for the purpose
set forth.
4. The improved regulatable disinfecting apparatus, constructed and arranged
substantially as herein before described and shown on the drawings annexed.
