Improvements in Apparatus for Supplying Rooms with Filtered and
Moistened Air.
1, EDWIN BREADNER, of Grosvenor Buildings, Deansgate, Manchester, in the County
of Lancaster, 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 :-
This invention has for its object to provide means whereby filtered and moistened
air can be introduced into and distributed in rooms in any desired volume and degree
of coolness.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a longitudinal section through line A--B Fig. 3, and Fig. 2 is a cross
section line C-D Fig. 1 of my improved apparatus. Fig. 3 is a plan thereof and
Fig. 4 shows the same in a small scale, applied inside a room.
In carrying out my invention and referring to the figures generally I form an air
shaft a containing a removable filter medium b, b' in connection with a spray brush c
and one or more draft fans d. The upper end a' of the said air shaft a see Fig. 4
is suitably in communication with the atmosphere, while the lower end contains the
aforesaid removable filter medium b, b¹ in a perforated basket e filled with coke bor
it may consist of a series of removable sieves or perforated partitions b¹ or a com-
bination of both coke b and sieves or perforated partitions suitably arranged. In
order to permit the removal of the said filter 6, 61 for cleaning or renewing purposes
I form the air shaft a on its side with a suitable door f and at its bottom with a drain
pipe 9 for the purpose of suitably running off the waste water. In connection with
the said air shaft a and its filtering mediums b, I employ one or more fans d suitably
rotated and secured thereto for the purpose of drawing fresh air through the same
and into the room where the air requires cooling and moistening. In drawing in
the air as described the same is moistened by means of a spray of water projected
onto the same by a brush c suitably rotated and fixed adjustably in a water tank h.
The brush c and tank h are mounted at the side of the air shaft a at a level above that
of the filter medium b, b' so as to moisten the ingoing air before it has reached the
filter medium 6, 61. The water tank his formed with an overflow i and is furnished
with a ball tap k which selfactingly admits the required quantity of water. In order
to moisten the air as required more or less spray of water can be produced by either
raising or lowering the brush c by means of screws l.
In connection with the fan or fans d I employ in some cases a perforated pipe or
pipes m by means of which the air can be distributed at any desired point in
the room.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is:
An apparatus for supplying rooms with filtered and moistened air, consisting of an
air shaft a containing a filter medium 6, 6¹ in connection with a rotary spray brush c
and one or more fans d, adapted to draw air through the said shaft a, which air is
moistened and purified respectively, by the spray brush c and filter medium b, b¹,
substantially as and for the purpose specified.
Dated this 13th day of September 1890.
