We, ERNST ACKERMANN and JOSEF KIEFER both of No. 12 Mariahilferstrasse in
the City of Vienna in the Empire of Austria, Engineers, do hereby declare the
nature of our said invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
Our invention relates to important improvements in apparatus for producing water
spray and rendering the air damp or humid; and consists in finally dividing the
fine jets of water issuing from a rose and rendering the air humid, not, as has
been so often attempted by allowing jets of water to impinge on a conical tip or
a resistance with spherical or spheroidical surface or by causing two jets of water
to impinge on each other at an acute or obtuse angle, but by forcing each of the
jets in an inclined direction so that the suctional action of the finely divided water
or spray will draw in a current of air which becomes impregnated with the finely
divided particles of the water.
Figure 1 is a vertical section of our improved apparatus.
Figure 2 is the elevation of the one end.
Figure the elevation of the other end.
The casing a is preferably of cylindrical form into which the ends or covers bb¹
are screwed and made watertight.
The end is provided with a central boring and a projecting part c_with_female
screw threads for screwing the apparatus onto the water supply pipe. Two three or
more small tubes d are let into the end b, the open ends of which are on the one.
hand in communication with the space within the walls of the ventilating tube g,
and on the other hand with a piece of tubing d¹ closed at e and arranged in the
interior of the cylindrical casing, the open end of the said piece of tubing d
being snugly and airtight fitted into the central boring of the end or cover b¹. On
the outside of the end or cover b₁ and across the boring we arrange several thin
plates pin such manner that they form a pyramid with star-shaped notched
surfaces and located with the base centrically over the open end of the piece of

cover b. The tapered borings frun in inclined direction through the end or cover b' so
that the outlet is directed exactly into the angle. formed by each two of the walls of
the plates p.
The aforedescribed apparatus is screwed onto the water supply pipe by means of
the screw threads in c and appropriately placed in the ventilating tube g.
The operation of the apparatus is as follows:
The water from the service pipe enters the apparatus at c and fills the same,
streams through the inclined tapered borings f in fine jets with a velocity corre-
sponding to the pressure in the service pipe and impinges against the angle
formed by the plates p where it is reduced to spray and sucks up the air passing
through the tubes d and the piece of tubing d. Air is continually sucked in
through the tubing d d, is thoroughly saturated with water and led off to the desired
point.
It will be understood that our improved apparatus can also be employed for leading
off spent or bad air and that the water used is by no means lost as it can be
appropriated for domestic and other purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we claim:
•
In apparatus for reducing water to spray and rendering air humid, for ventilating
purposes:
1. The arrangement for finely dividing water or reducing the same to spray by
causing fine jets of water to impinge against the angles of a pyramid with notched
surfaces and star shaped base, substantially as described and shown.
2. In. devices as described in the foregoing claim the air feed in which the air
sucked in passes tubes arranged within the water chamber and ending at the basis of
the pyramid, substantially as described and shown.
