PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Moistening Air and
Freeing it from Dust.
A communication to me from abroad by JACOB MUNK, of Viaductgasse, 20,
Vienna, in the Empire of Austria, Engineer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane; in the County of
Middlesex, do hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in apparatus for moistening air and
freeing it from dust.
The improved apparatus consists of a revolving frame provided with a system of
surfaces of a porous material from which the water is evaporated, in combination
with a fan which is arranged inside the evaporating surfaces (or separate from
them, and connected by a suction pipe or by a compression pipe) and provided with
a water tank underneath the evaporator.
By any convenient motive power the fan is set in rapid revolution whilst the
evaporator is made to revolve slowly, and by the powerful stream of air passing
over the surfaces of the evaporator, which take up the water whilst passing
through the water tank, the water is evaporated in proportion to the warmth and
the quantity of the air, which carries the evaporated water or vapour along,
whilst the dust etc. suspended in the air passing through the evaporator is kept
back by the porous material of the wet surfaces and the air becomes thoroughly
damped and is entirely freed from dust. If the suction pipe of the exhauster or of
the fan is directed outward to a suitable locality an entire or partial change
of air is effected, as well as the moistening of the latter and the removal of the
dust from it.
The evaporator may be dispensed with if the air is to be cleaned only, and not
to be moistened simultaneously. In such case the air drawn by the fan may be
thrown against the surface of the water in the tank, which keeps back all parts of
the dust. Such an arrangement may consist of a double fan and two suction pipes,
and a closed case provided with openings directed against the surface of the
water.
The purified air is delivered through a pipe, and an entire or partial renewing
of the air can be obtained by bringing the suction pipes from any suitable external
locality.

Improvements in Machinery or Apparatus for Moistening Air and
Freeing it from Dust.
A communication to me from JACOB MUNK, of Viaductgasse, 20, Vienna, in the
Empire of Austria, Engineer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention and in what manner the
D017

page_text: same is to be performed, to be particularly described and ascertained in and by the
following statement and accompanying drawing, that is to say :--
1
This invention relates to improvements in apparatus for moistening air and
freeing it from dust.
In the accompanying drawing,
Figure 1 shews longitudinal and transverse sections of the apparatus.
Figure 2 shews a transverse section of a somewhat modified form and
Figure 3 shews longitudinal and transverse sections of another modification.
The improved apparatus consists of a revolving frame provided with a system
of surfaces (Figures 1 and 2) of a porous material from which the water is
evaporated in combination with a fan V which is arranged inside the evaporating
surfaces (or separate from them, and connected by a suction pipe or by a com-
pression pipe) and provided with a water tank underneath the evaporator.
In Figure 1A is the evaporator, W the water tank, V the suction ventilator
inside the evaporator or helical or centrifugal fan or air propellor; in Figure 2
A is the evaporator, W the water tank, and V the suction and compression fan
arranged outside the evaporator and connected therewith by a suction pipe. By
any convenient motive power the fan is set in rapid revolution, whilst the
evaporator is made to revolve slowly and by the powerful stream of air passing
over the surfaces of the evaporator which take up the water whilst passing through
the water tank, the water is evaporated in proportion to the warmth and the
quantity of the air, which carries the evaporated water or vapour along, whilst the
dust etc. suspended in the air passing through the evaporator is kept back by
the porous material of the wet surfaces and the air becomes thoroughly damped and
is entirely free from dust. If the suction pipe of the exhauster or of the fan or of
the suction and compression fan (Figure 2) is directed downward an entire or
partial change of air is effected, as well as the moistening of the latter and the
removal of dust from it.
The evaporator may be dispensed with, if the air is to be cleaned only, and not
to be moistened simultaneously.
-
In such case (as illustrated in Figure 3) the air draws by the fan may be thrown
against the surface of the water in the tank, which keeps back all parts of the
dust. Such an arrangement may consist of a double fan and two suction pipes,
and a closed case provided with openings directed against the surface of the
water.
The purified air is delivered through a pipe Z, and an entire or partial renewing
of the air can be obtained by bringing the suction pipes from any suitable external
locality.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The evaporating surfaces, consisting of a frame covered with a porous
material, in combination with. a fan, such as a centrifugal or helical fan or air
propellor which is arranged inside the evaporating surfaces (Figure 1) or at a
distance from it and connected therewith by a suction or compression pipe
(Figure 2), and a water tank W underneath the evaporator.
2. The suction and blowing fan (Figure 3) without the system of evaporating
surfaces, in combination with a water tank W, disposed underneath the blowing
openings, all substantially as described and represented in the drawing.
