PROVISIONAL SPECIFICATION.
A New or Improved Apparatus for Disinfecting or Odorizing
Purposes.
I CHARLES CARROLL LEATHERS, of 9 Rue de la Chaussee d'Autin, Paris,
France, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved apparatus for disinfecting or
odorizing purposes, and consists in providing an apparatus for distributing a
continuous current of suitably odorized air, for the purpose of disinfecting, or
destroying the germs in, the atmosphere of hospital wards, theatres, and similar
places.
According to my invention, I provide a suitable chamber or case divided into
two compartments, in one of which I place a perforated metal or other cylinder,
open at one end for the free access of the odorized air to the atmosphere.
In the other end of this perforated cylinder is a revolving fan working in suitable
bearings, and driven by means of an electro-motor or other suitable motive power,
which is stored in the second compartment. If desirable, I can dispense with this
second compartment, and obtain the power requisite for rotating the fan, from any
suitable outside source.
The space around the perforated cylinder, in the first compartment, will be
packed with sawdust chalk, earth, fibre, cotton-wool, or similar substance or
material, impregnated with any suitable deodorizing or disinfecting substance.
In lieu of packing the space around the cylinder with dry material impregnated
with liquid or other deodorizing substance, I may provide a chamber beneath the
revolving fan, and fill same with a liquid deodorizing substance, which can be
conveyed to the fan by capillary attraction or in any other suitable manner.

COMPLETE SPECIFICATION.
A New or Improved Apparatus for Disinfecting or Odorizing
Purposes.
I CHARLES CARROLL LEATHERS, formerly of 9, Rue de la Chaussee d'Antin,
Paris, France, and now of 122 to 124 Charing Cross Road, London, Merchant, 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:
My invention relates to a new or improved apparatus for disinfecting or odorizing
the foul air in hospital wards sick roums, theatres, and the like and consists of a
receptacle or chamber in the centre of which is arranged a fan rotated by a small
motor electric machine fitted in the rear end of the chamber and revolving within
a perforated metal casing preferably of cylindrical shape, fixed in the front part of
the said chamber. The space around the said perforated casing may be packed
with sawdust, earth, tow, cotton, wool, or other similar material impregnated with
any suitable odorizing or disinfecting substance, the fan driving a volume of the
surrounding air in contact with the disinfectant when after being saturated, the
Price 271

page_text: same returns into the atmosphere of the room where the apparatus is fixed in order
to be replaced by a fresh volume of contaminated air. Or I may instead pour
liquid disinfectant in the bottom of the chamber below the perforated cylinder up to
any suitable height.
In the accompanying drawings,
Fig. 1 is a front elevation, and Fig. 2 a plan with the cover open of my improved
disinfecting, odorizing or medicating apparatus.
Fig. 3 is a section at right angles to Fig. 1.
Fig. 4 is a diagrammatic view shewing the apparatus in position in a room or
chamber.
Like letters of reference indicate corresponding parts throughout the figures.
My apparatus consists of a box or receptacle B divided by a perforated
partition (Fig. 3) into two chambers c and c¹ (Fig. 2) and covered by a hinged
lid m, a handle h (Figs. 1 and 3) being provided for convenience of carriage. In
the front chamber c is arranged a cylinder C of wire gauze or perforated metal
fixed in the centre of the said chamber. A fan F is mounted on an axis s rotated by
the dynamo-electric motor machine D placed in the rear chamber c or by any other
suitable motor, this fan moving just in front of the partition p and being furnished
with a central conical extension a of wire gauze or perforated metal, containing any
suitable porous textile or other material impregnated with any suitable disinfecting,
odorizing or medicating substance. The chamber is closed at the top and is
furnished with three openings closed by screws d through which the disinfectant,
deodorizer or medicating substance is poured in a liquid form upon the textile or
other packing P stuffed around the perforated cylinder C.
The front opening in the box B is protected by a guard g, while the same box
is furnished with two openings at the side covered by wire gauze or perforated
metal panels. As the fan Frevolves, it exhausts the air through the panels p
and as this air is drawn outwards through the plate p, it is brought in contact with
the material P, thus disinfecting, odorizing or medicating the same according to
the
purpose in view.
Fig. 4 shows the apparatus in position against a wall, supported by the brackets b.
Below the same is arranged a resistance and switch-board f carrying a sinall
incandescent lamp and by means of which the intensity of the electric current from
the battery to the apparatus can be regulated.
K. is a cord formed of insulated wires and connected at one end to the
terminals of the apparatus and by strands to the terminals of the switch
board as shown, this cord carrying at its other end a contact piece v whereby the
apparatus may be inserted into any suitable electric circuit such as used to supply
electric lamps or the like. The terminals are connected to the motor as shown in
Fig. 3.
In the case of public buildings or wherever the air is very foul, I connect the
box B with the outer atmosphere by means of a pipe fixed at one end to the
back thereof, while its other end passes through the wall of the building to which
this apparatus is fixed and leads outside to an angular pipe or hood.
The fresh air is drawn from the outside through this pipe and is disinfected or
odorized in the box by contact with the material impregnated with the disinfectant
or odorizer, while the foul air is exhausted through the side panels and exits through
the same pipe.
I may also form a receptacle below the fan and fill the same with the disinfecting,
odorizing, or medicating liquid which is raised to the top of the apparatus by
means of suitable wicks, fibres, or other material extending along the inner sides
of the box.
One of the chief advantages of my system is that the air is thoroughly filtered
on its passage through the perforated panels p' and plate p, and that it is so
distributed into the room or chamber as to create no draught whatsoever, so that
any person sitting in close proximity to the apparatus, will not be inconvenienced

page_text: thereby, as is the case with ordinary ventilators. The conical piece a may in some
cases be filled with perfume so as to counteract the smell of the disinfectant taken
up by the air.
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. In apparatus for disseminating liquid disinfectants, odorizers, medicaments or
the like, the arrangement of a central perforated receptacle through which the air
filtered and saturated with one of the above substances is expelled by a distributing
fan driven by an electric or other motor, the whole being enclosed in a casing
furnished with side panels through which the foul air is drawn in order to be
conveyed to the perforated receptacle aforesaid substantially as herein described
and shown in the drawings.
