I JOHANN JANKA of Tischlergasse No. 1107-II Prague, Austria, Plumber, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in "spray" ventilators for living and other
rooms which differ from the others hitherto in use for their simple construction and
easy operation; they can be regulated and the water enters the spray producer already
filtered so that the atomizer is not stopped up by any matter suspended in the water.
It consists essentially in a U shaped tube of any desired section one leg of the tube
opening in to the room to be ventilated and the other leg being in communication
with the outer air. A single pipe supplies the atomizers with the necessary water,
the pipe branching off shortly before reaching the atomizers in the legs. Two spray
producers are used one to introduce fresh air into the room and the other one to suck
air out of room to be ventilated.
My improved spray producer consists essentially in a hollow pear shaped vessel
fixed to the water pipes by a short tube like projection; on the lowest point the vessel
is provided with a round hole in which works a conical pin which when in its highest
position completely fills the hole so that no water can escape. If the pin be lowered
a little by a rack and pinion arrangement the rack being on the pin itself and the
pinion on a spindle reaching through the side of the vessel and provided with a
button a small annular opening will be produced round the conical pin through which
the water will be forced in a conical ring of spray. The more the pin is lowered
the wider the ring will become and the more water will be emitted. The force of the
water and in consequence the draught produced can therefore be regulated or entirely
shut off by the button.
A further improvement is the cleansing or filtering of the water before it reaches
the atomizer to prevent the atomizer from being stopped up. At a convenient place
the water supply pipe is cut and a piece of tubing of an inner diameter equal to the
outer diameter of the supply pipe and having at one end a left handed at the other a
right hand female screw thread is screwed onto the ends of the supply pipe. Into

page_text: this tube is placed a vertical wire into which are fixed two or more fine meshed wire
sieves of the same diameter as the tube, the lowest one resting on the edge of the
supply tube and having the widest meshes while the others are gradually finer the
finest meshed being at the top. At a certain distance from and underneath the tube
surrounding the sieves a little cock is provided and underneath this a stop valve of
the supply pipe. If the tube is adjusted and the stop valve opened the water will
pass through the sieves and will reach the spray producer almost filtered the solid
matter remaining against the sieves. If the sieves are to be cleaned the stop valve is
shut and the outlet cock opened when the water standing above the same will run out
and carry the dirt accumulated against the sieves down and out with it. If it be
desired to take the sieves out and clean them thoroughly the larger tube is screwed
down and passed over the smaller one when the sieves can be removed. If desired
an extra sieve can be arranged inside the pear shaped vessel of the spray producer.
Through the outlet cock also water may be drawn off at any time for domestic or
other purposes.
The water from the spray producers is run off through a tube let into the bend of
the shaped tube.
The ventilator may be double acting with a spray producer arranged in each leg so
that if one only is playing the air is sucked from the room if the other only is playing
fresh air is introduced and when both are playing at the same time the air is sucked
from the room and fresh air introduced. Both spray producers may in this case also
be supplied by one water supply pipe.
The ventilator may be either horizontal or vertical and is susceptiblée of other
modifications.

page_text: I, JOHANN JANKA of Prague, Austria, Plumber, 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 relates to improvements in "spray" ventilators for living and other
rooms which differs from the others hitherto in use through their simple construction
and easy operation; they can be regulated and the water enters the spray producer
already filtered so that the atomizer is not stopped up by any matter suspended in the
water. Fig. 1 of the accompanying drawings represents a vertical section of a venti-
lator provided with my improvements. It consists essentially in a U shaped tube A A¹
of any desired section, one leg of the tube opening into the room to be ventilated
and the other leg being in communication with the outer air. A single pipe B supplies
the atomizers E and F with the necessary water the pipe B branching off shortly
before reaching the atomizers in the legs D. Two spray producers F are used one
to introduce fresh air into the room and the other one to suck air out of room to be
ventilated.
Fig. 2 represents a spray producer in vertical section and consists essentially in a
hollow pear shaped vessel a fixed to the waterpipes C or D by a short tube like
projection ; on the lowest point the vessel a is provided with a round hole o in which
works a conical pin c which when in its highest position completely fills the hole o so
that no water can escape. If the pin c be lowered a little, by a rack and pinion
arrangement d and the rack being on the pin itself and the pinion on a spindle
reaching through the side of the vessel and provided with a button d, a small annular
opening will be produced round the conical pin c through which the water will be
forced in a conical ring of spray shown in Fig. 2 a representing a horizontal section on
the line y of figure 2. The more the pin c is lowered the wider the ring will become
through which the water is forced and the more water will be emitted. The force of
the water and in consequence the draught produced can therefor be regulated or
entirely shut off by the button d.
Figs. 9, 9 a, 10, 10a, 10 b, represent modifications in the construction of the atomizer
differing from the above described construction essentially in the handling and
construction of the conical pin c. If the conical pin c fig. 9 is in its highest
position the hole o of the atomizer is perfectly free and the water passes through
in an unbroken jet. When the pin c is lowered it will enter the hole o only leaving
an annular opening around it see fig. 9a which is a plan of fig. 9 through which
the water is forced in form of a cone and finely atomized. By lowering or raising the
pin the annular opening and the amount of water passing is regulated. The
opening o is closed entirely by lowering the pin so far that its upper part which is
wider in diameter than the opening o rests on the latter.
A further modification is represented in fig. 10. Here the conical pin c is screwed
into the rod c¹ through the opening o which is of smaller diameter than the lower part

page_text: of the pin e so that the opening o will be closed when the pin c is lifted and opened
when the pin c is lowered when the water will be forced out through the annular
opening forming.
The raising or lowering of the pin c which works in a guide y may be effected by
means of a pivotted lever system as represented in Fig. 9 or,preferably by the
mechanism represented in figure 10, 10a, 10 b. In this mechanism a tube d is soldered
to the side of the atomizer a into which tube fits watertight a pin to this pin is fixed
inside the atomizer a bent lever i to the end of which is pivotted the rod c¹. The tube d
is provided with a slot where the bent lever i passes into the atomizer. When the
pin is turned by the handle m or otherwise the lever i will either raise or lower the
rod c carrying the conical pin c: If an atomizer of such construction be used in
ventilator tubes the pin may be turned from the outside by a lever', and rod h with
knob kat bottom as represented in figure 8.
A further improvement is the cleansing or filtering of the water before it reaches
the atomizer to prevent the atomizer from being stopped up. This arrangement is
constructed as follows:-At a convenient place the water supply pipe B is cut and a
piece of tubing W, fig: 3 of an inner diameter equal to the outer diameter of the
supply pipe Band having at one end a left handed at the other aright hand female
screw thread, is screwed onto the ends of the supply pipe B. Into this tube W is
placed a vertical wires onto which are fixed two or more fine meshed wire
sieves S, S', S² of the same diameter as the tube W the lowest one resting on the edge
of the supply tube B and having the widest meshes, while the others are gradually
finer, the finest meshed being at the top. At a certain distance from and underneath
the tube W surrounding the sieves, a little cock H is provided and underneath this a
stop valve J of the supply pipe B. If the tube W is adjusted and the stop valve J
opened the water will pass through B and W through the sieves S, S¹, S², and will
reach the spray producer almost filtered the solid matter remaining against the sieves.
If the sieves are to be cleaned the stop valve J is shut and the outlet cock H opened
when the water standing above H will run out and carry the dirt accumulated against
the sieves down and out with it. If it be desired to take the sieves out and clean
them thoroughly the larger tube Wis screwed down as in fig. 4 and passed over the
smaller tube B when the sieves can be removed. If desired an extra sieve can be
arranged inside the pear shaped vessel a of the spray producer. Through the outlet
cock H also water may be drawn off at any time for domestic or other purposes.
Although the water enters the atomizer in an almost pure condition it passes in the
latter through a further supplemental sieve and should the atomizer nevertheless
shecome stopped up with impurities it is only necessary to lower the conical pin c'to.
its utmost extent and the force of the water will carry away all accumulated
impurities:

The water from the spray producers is run off through a tube I let into the bend
of the U shaped tube.'

Figs. 5, 6, 7 are modifications of the ventilator..
Fig. 5 represents a ventilator the tubes A A' are close together to economise space.
Fig. 6 represents a double ventilator with a spray producer arranged in each leg so
that if the spray producer E only is playing the air is sucked from the room if only
is playing fresh air is introduced and when both are playing at the same time, the air
is sucked from the room and fresh air introduced. Both spray producers are in this
case also supplied by one water supply pipe B only.
Fig. 7 represents a double ventilator horizontally arranged either one above the other
or next to each other but it may be also vertically arranged and is susceptible of other
modifications.
