Improved Apparatus for Supplying Fresh, Cool, or Warm and
Moistened Air to Enclosed Spaces of any kind.
I, MICHAEL KUGLER, of 4, Bajza-utcza, Budapest, in the Kingdom of Hungary,
Railway 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:-
The object of the present invention is an apparatus for supplying fresh, cold
or warm air to houses, residences, railway trains and the like, which consists
essentially of a bell 6 (Figures 1 and 2) serving as an air pump, which immersed
in a reservoir of water a, is moved up automatically maintaining the water seal,
and sinks by its own weight which can be varied as desired. By means of this
special method of propulsion and this special arrangement the bell used as an air
pump is specially suited for the purpose of conveying air into dwellings, rooms, and
the like, and has the advantage of effecting a uniformly still motion of the water
in which the bell air pump works. The water cannot splash or foam and thus
cause the air to become too moist as the bell slowly operates, pressing on the
contacts of air in the globe only by its own weight. Consequently there is
always a uniform state of pressure in the air-pipe.
In the device moreover there are two such bell air pumps in connection with
one another, operated from the same shaft, therefore is also attained a uniform
loading of the motor, producing a continuous current of air in the pipe.
The device is illustrated in the accompanying drawing in which:-
Figure 1 is a cross section.
Figure 2 is a view from above
Figure 3 is a detail.
Figure 4 shews the method of applying the apparatus to a dwelling house.
Figures 5 and 6 shew its application to railway carriages, and
Figure 7 its application to the cabins of ships.
The bells b b are provided within with a pipe conducting the air and projecting
above the level of the water, which pipe is fitted with a suction valve f; there is
also an air pipe h provided with a pressure valve i.
As shewn, the bell is suspended by the cords which again is secured to a
crank disc o. This effects the regular working of the apparatus for producing
a given pressure of air, the motor being driven as fast as desired; the bells 6 can
be weighted as desired, and the bell, merely pressing down in consequence
of its own weight, and thus perfectly uniformly, operates upon the air enclosed
which causes the level of water in the reservoir a to rise higher than within the
bell. There cannot be, however, as is unavoidable when the working is by a
crank or the bell is rigidly connected to the pulley, an alternately quicker and
slower pressing down of the bell. If the motors be rigidly joined to the bell,
a quiet uniform current of air of equal pressure by means of contact with the
walls of the bell could not be attained and the result would be that the water would
be churned up, and the working and usefulness of the pump be impeded.
There is another advantage which the apparatus offers which is not to be under-
DR77

page_text: valued, namely that owing to the free fall of the bell, the motor can never be
overloaded or a loading of the motor be required as in case of a rigid connection
may easily happen because the difference between the outer and the inner level of
the water in case of a too fast downward pressure of the bell by means of the
motor (in consequence of a rigid connection) is changed exceedingly quickly,
which would of course result in increased and undesirable pressure, and the
increase of power applied damages the apparatus. In the improved not rigid
suspension of the bell the apparatus is much more independent of the strength
of the motor of whose number of rotations it is independent, causing uniform
pressure and minimum disturbance of the water.
To the tube g a long suction pipe can be connected, conducting from the
place (garden, wood and the like) whence the fresh air is to be taken. The
pressure tube h conducts to the rooms which are to be supplied with air:
Or the suction valve f can be located directly on the cover of the bell (Figure 3)
which does away with the suction pipe g.
In Figures 4 to 7 are illustrated examples of special applications of this
apparatus.
Figure 4 shews the cross-section of a house.
The apparatus is placed in the cellar. The suction pipe g is passed through the
wall into the outer air, but the pressure pipe h on the other hand is conducted
into the house and passes into the room where the air can flow out freely as
required.
The pressure pipe branches off at c one branch conducting to the heating
chamber d where air can be warmed in winter and be conducted thence into the
room through the tube e.
In place of d or near d a refrigerating apparatus can be arranged where the air
can be cooled in summer, the required air is led through the passages k.
In Figures 5 and 6 the application of this apparatus to railway carriages is
illustrated, where the heating of the air takes takes by means of steam.
Figure 7 shews the same device applied to a ship.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
Apparatus for supplying fresh, cold or warm air to houses, residences and holds
or cabins of steamers and the like characterized by a freely falling bell serving
as air-pump which dips into a reservoir of water is raised by machinery under
canstant water seal and uniform air pressure inside the globe, the said bell being
supplied with pipes for supplying and taking away the air having suitable valves
for the purpose of obtaining a uniform pressure and moistened air, substantially
as described.
