PROVISIONAL SPECIFICATION.
An Improved Method of and Apparatus for Ventilating Buildings
Ì, FRIEDRICH ERNST GATCKE, of 15 Marktstrasse, Altona Bahrenfeld in
the Empire of Germany, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved method of and apparatus for ventilating
buildings, and has for its special object to ventilate or cool rooms, especially
factory workshops, boiler rooms and the like. According to my invention
I provide a winged wheel or fan or similar rotary body in the interior of the
room or apartment to be supplied with fresh air, while fresh air is duiven under
pressure against such wheel or 10tary body, in such a manner that the fan or the
like against the vanes or wings of which the air current 18 forced, is caused to
rotate and thereby to distribute the fresh supply of an all over the room and
thoroughly mix the same with the air of the room.
For examplo in a boiler room the aforesaid fan on winged wheel is rotatably
Arranged in front of and above the boiler, and against the vanes of the said fan
fresh air is forced under pressure from outside the room through a suitable pipe.
The air distributed by the wheel will supply the stoker with cool air without
exposing him to open draught.
This improved method of ventilating is far superior to those, by which air 18
sucked into the room by means of mechanically evolved blowers or fans, since
such sucked in an 18 distributed by the blower or ventilator inside the room
oper only to a restricted degree and in an inefficient manner. On the other
hand this improved method of ventilation differs from the usual methods of
distributing freshly supplied air inside the room, in that up to the present time
it has not yet been attempted to cause the fresh an, supplied under pressure,
to act as a motor for its own distribution, the latter being arranged neither within
o outside the wall of the 100m but in the room itself, thus utilizing the air
itself indirectly for its own distribution. The advantage of this is that the
distributing body inside the room does not require any mechanical power to dive
it other than the an pressure and therefore occupies comparatively little space,
and that nevertheless moving and not stationary surfaces are present inside the
room to be ventilated, which surfaces distribute the fresh air not on one side
only or upon a limited space but all over the room, thus thoroughly mixing the
freshly supplied air with the air of the room, without any persons within the room,
being exposed to draught injurious to health.
The number of fans or distributing bodies to be provided in a room is dependent
upon its size and other local conditions. Moreover the number of fans, the
construction thereof and the places at which they are situated may, without
difficulty, be so arranged that the distribution of the air does not take place
arbitrarily but is effected in such a manuer as appears most suitable for the
purpose.

I, FRIEDRICH ERAST GATCKE, of 15 Markstrasse, Altona Bahrenfeld, in
the Empue of Germany, Manufacture, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertamed in and by the following statement :-
This invention relates to an improved method of and apparatus for ventilating
buildings, and has for its special object to ventilate o cool 100ms, especially
factory workshops, boiler rooins and the like.
According to my invention I provide a winged wheel or fau or similar rotary
body in the interior of the 100m or apartmont to be supplied with fresh air, while
fiesh air is diven under pressure against such wheel or rotary body, in such a
manner that the fan or the like against the vaues or wings of which the air current
is forced, is caused to rotate and thereby to distribute the fresh supply of air all
over the room and thoroughly mix the same with the au of the room.
In order that my invention may be more fully understood I will now proceed to
describe the same in detail and for that purpose shall refer to the accompanying
drawing which shows one form of causing out the invention.
A fan or winged wheel a is rotatably manged for example in a boiler room R
in front of aud above the boiler B and against the vanes of the said fau fresh air
18 forced under pressure from outside the room through a suitable pipe b. The air
distributed by the wheel will supply the stoker with cool air without exposing him
to open draught.
This improved method of ventilating is far superior to those, by which air is
sucked into the room by means of mechanically revolved blowers or fans, since
such sucked in air is distributed by the blower or ventilator inside the room
proper only to a restricted degree and in an inefficient manner. On the other
band this improved method of ventilation differs from the usual methods of
distributing freshly supplied air inside the 100m, in that up to the present time it
has not yet been attempted to cause the fresh air, supplied under pressure to act
as a motor for its own distribution, the latter being arranged neither within or
outside the wall of the room but in the 100m itself, thus utilizing the ant itself
indnectly for its own distribution. The advantage of this is that the distributing
body inside the room does not requne any mechanical power to drive it other than the
an pressure and therefore occupies comparatively little space, and that nevertheless
moving and not stationary sui facca are present inside the room to be ventilated,
which sm faces distribute the fresh air not on one side only or upon a limited space
but all over tho room, thus thoroughly mixing the freshly supplied air with the air
of the room, without anyone within the room, being exposed to diaught injurious
to health.
The number of fans or distributing bodies to be provided in a room depends
upon its size and other local conditions. Moreover the number of fans, the
construction thereof and the places at which they are situated may, without
difficulty be so arranged that the distribution of the air does not take place
arbitrarily but is effected in such a manner as appears most suitable for the
purpose.
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. An improved method of ventilating buildings, rooms, and the like consisting
in driving fresh air under pressure against a winged wheel or fan or similai otary
body in the interior of the room or apartment to be ventilated, iu such a manner,

page_text: that the distributing means against which the air current 18 forced is caused to
rotate or move and thereby to distribute the fresh supply of air all over the 100m
and thoroughly mix the same with the air of the room, substantially as set forth
2. Apparatus for ventilating buildings, rooms and the like consisting of an air
distributing means such as a winged wheel, fan or suitable rotary body arranged
in the room to be ventilated and adapted to be set in motion by the ventilating an
itself supplied under pressure through a suitable conduit and directed against the
Baid air distributing means, substantially as specified.
