VODE LEIE SPECIFICATION,
Improvements in Apparatus for use in Disinfecting by means of
Antiseptic Liquids.
I CHARLES HERSCHER of the firm of Geneste Herscher & Cie. of 42, Rue du
Chemin Vert, Paris in the Republic of France, Engineer, 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 :-
This invention has for its object a disinfecting apparatus, which, by pulverising
or atomising an antiseptic liquid, will disinfect those places which have become
contaminated by a sick person being in them, or which have become injurious
owing to a contagious affection or from any other cause.
To attain the desired object, it must not be thought that it will suffice to employ
heat alone, or even superheated vapour, which, in ordinary apartments, would
seriously spoil the wall papers, paintings, etcetera. The action of gaseous
disinfectants is not sufficiently efficacious, and, when such is employed, all openings
have to be carefully stopped up, the operation is also a prolonged one and the parts
must be subsequently exposed to the open air for 12 hours at least before the rooms
can be again occupied.
A much preferable method is that which consists in sprinkling the walls, ceilings
and floorings with a disinfecting solution, but subject to the condition that all points
of the contaminated parts are thoroughly reached, and that with the least possible
quantity of antiseptic solution.
We attain this double object by means of the apparatus forming the object of
the present invention and by the use of which the liquid discharged into a
pulveriser or atomiser escapes with force, mixed with compressed air, and in the
form of very fine rain or rather of a cloud.
The invention will be best understood by reference to the accompanying sheet of
illustrative drawings on which-
Figure 1 is a vertical section of the apparatus.
Fi
igure 2 a section across the suction and discharge conduits of the air pump.
Figure 3 a section on an enlarged scale of the pulveriser or atomiser.
Figure 4 an exterior view of the apparatus mounted on a truck.
The apparatus is composed of a reservoir generally of a cylindrical form having
two compartments A and B divided by a horizontal partition F. A tube E places
these two compartments in connection with each other.
To the cover of the compartment A an air pump C is fitted, the piston D of
which is formed preferably of a cover of leather drawn between two metallic parts.
This piston is actuated by hand by means of the lever I, one extremity of which is
hinged to the end of the support J and the piston rod H is jointed to this rod I.
The suction and discharge conduits T are shown in detail in Figure 2 which is a
section on the line y of Figure 1.
The suction part d has an orifice closed by a spring valve f, which is capable of
being regulated. The discharge part e contains a ball valve e which opens at the
desired moment the side orifices, whereby communication with the reservoir A is
established. The body of the pump is besides pierced with openings o which place
it in connection with the exterior when the piston is at the end of its travel.
A tube G used for lifting the liquid penetrates to the bottom of the reservoir B
and tomminator

discs is pierced with a conduit of very small diameter placed in an oblique direction,
so that they can be easily got at with a needle. The tube g is closed by a screw
stopper J. The antiseptic liquid which is brought through this tube traverses in a
zig-zag direction through the discs and is obliged to pass successively through all
the inclined conduits before arriving by means of conduit to the pulveriser or
atomiser k properly so called. In practice there will result by this arrangement a
great economy in the quantity of liquid injected and a remarkable facility in
rendering that quantity sufficient without being excessive.
The compressed air enters by the tube h and gushes out by the divergent orifice
of the cap k, thereby pulverising or atomising the liquid contained in the part
around the fitting.
On the wall of the reservoir B a tubular funnel K is fitted with a tap operated
by a handle L. The bottom of the reservoir which is slightly conical is supplied
with an emptying tap R. Finally the apparatus may be transported from one place
to another by holding the handle S so that it can then rest on two wheels Q.
Figure 4 shows the same apparatus hung in a framework of a two wheeled
truck Q:
The air pump, Figure 4, is a little different from that shown in Figure 1. The
body of the pump at its upper part is open to the free air and the piston carries the i
suction valve. The discharge valve e is at the bottom of the body of the pump.
Our apparatus may be applied for disinfecting the walls of private houses, of
public establishments, of barracks, of hospitals, of ships, as well as those of stables,
stalls, etcetera, and also vehicles which are used for transporting wounded or sick
persons, it may also be used for disinfecting railway upholstery, etcetera, fittings,
sanitary establishments, contaminated dwellings, etcetera.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is-
1. The improvements in disinfecting apparatus by which an antiseptic liquid can
be, as it were pulverised or atomised, which consists in the employment of
reservoirs A and B, communicating with each other by means of the tube E, in
combination with an air pump C, the evacuating orifices a and b, and the pulveriser
or atomiser P as has been described with reference to Figures 1 and 2 of the
drawings.
2. In an apparatus for disinfecting the walls of contaminated places, the
pulveriser or atomiser P, consisting of the tube g having discs i pierced with
oblique conduits, the tube having its conical nozzle and cap & with divergent
orifice, and finally the communication channel 1, substantially as hereinbefore
described and shown.
3. The wheeled apparatus for use in disinfecting the walls of contaminated places,
which consists of the reservoirs A and B, an air pump open at its upper part the
piston of which carries the suction valve, and the lower part the discharge valve in
combination with tubes M and N, the pulveriser or atomiser P, and the wheeled
truck S Q, all substantially as hereinbefore described and shown.
