Improvements in Humidifiers.
I, JOHN TAYLOR of the firm of Dowson, Taylor and Company "Limited," of
Blackfriars Bridge, Manchester in the County of Lancaster, Fire Engineers, do
hereby declare the nature of my said 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 humidifiers for moistening or saturating
air in mills, weaving sheds, factories, and other buildings, and consists in an improved
arrangement or construction of apparatus by means of which any desired degree of
humidity of the air may be obtained.
Fig. 1 is a sectional elevation of my improved humidifying apparatus through
line A B in Fig. 2 wherein the water is propelled in a downward direction. Fig. 2 is
a plan of same.
Fig. 3 is a side elevation of propelling nozzle.
Fig. 4 is a sectional elevation of filter for water supply pipe.
Fig. 5 is a part section of apparatus showing position of separating plates or
regulators to vary fineness or quality of the spray.
Fig. 6 is a sectional elevation of my invention wherein the water is propelled
in an upward direction.
Fig. 7 is a plan of Fig. 6.
Fig. 8 is a side elevation of my invention wherein the water is propelled in a
horizontal direction and
Fig. 9 is a sectional plan of same.
In all the figures the same letters are employed to indicate corresponding parts.
A is the air inlet tube of any convenient length according to the area or space
over which the humidifying apparatus is to operate; B is a casing or cylinder,
which may be disposed below, above, or on the side or end of the air supply
pipe A; C the adjustable propelling nozzle; D the dispersing or pulverizing grid;
E separating plates or regulators; the water supply pipe; G the filter; H water
return pipe, and I distributing trays or outlets from the apparatus.
This apparatus consists of the air inlet tube A, to which is attached the casing or
cylinder B. The latter is secured to the distributing trays or outlets I, which may
be of any convenient or desired length according to the area or space the apparatus
is intended to operate over. The distributing trays or outlets I are provided with
the conoid or prism L for dividing the same to direct the treated air in both
directions along the distributing trays or outlets. To the outside of the air tube A
is fixed the filter G; the latter being supplied with water from a pump or other
source under pressure by means of the supply pipe F and valve J. To the outlet K
of the water filter G is attached the pipe F, which extends across the air inlet
tube A. From the pipe F¹ is suspended the propelling nozzle C, provided with the
adjustable.conical pin M attached to the screwed nut N mounted on the threaded
end O. The latter is secured to the nozzle C by means of the arms P. The
conical pin M is adjustable for the purpose of altering or regulating the impact of
water delivered in the wire or other dispersing grid D fixed in the casing or
cylinder B. The latter is fitted with the sliding door Q to allow of the conical
pin M being adjusted as required. The distributing trays or outlets L are fitted
with the separating plates or regulators E, the latter being mounted on the pivots R,
and operated by means of the levers S by the rod T. When it is desired to
produce a finer spray of humidified air it is effected by pushing up the rod T until
the separating plates or regulators E assume the position shown in Fig. 5, by

page_text: which the area of the outlets are decreased and the breaking up surface
increased.
For the purpose of preventing or minimising the risk of the nozzle C
being choked with deleterious matter that may flow with the water the filter G is
provided consisting of the internal tube U filled with sponge or other filtering
medium W. The internal tube U is attached to the cap or plug V constructed to
close the entrance to the cavity or chamber X between the outside of the internal
tube U and the inside of the outer tube or casing G. The cap or plug V is screwed
into the metallic fixing or end Y; the joint being made by the pliable washer Z.
Water is admitted from the supply pipe F through the openings C₁ and through
the sponge or filtering medium W as indicated by the arrows.
After the water
has passed the full length of the internal tube U it falls down the cavity or
chamber X to the outlet pipe F¹ and away to the propelling nozzle C. The upper
end of the filter G is closed by the metallic end D'.
In the modification of this invention shown in Figs. 6 and 7 the underside of the
casing or cylinder B is fitted with the circular dish or air inlet A, on which is
mounted the conoid or prism L, for the purposes hereinbefore set forth. In this
arrangement the water is propelled in an upward direction into the dispersing or
pulverizing grid D in a conical sheet, with the effect that the water at its outer
edge is pulverized or broken up into a fine spray, the fine particles of which unites
with and passes away with the atmospheric air drawn in the dish A on the lower
end of the casing or cylinder B. Water that is not broken up sufficiently fine to
unite with the current of atmospheric air drops or falls back into the dish A and
passes through the perforated bottom of the conoid or prism L and away by the
pipe H. The humidified air is delivered by the outlet pipes I, which may be of
any desired form or length. The pipes 1 are provided with the separating plates
or regulators E for the purpose previously set forth.
In the modification shown in Figs. 8 and 9 the casing or cylinder B is fitted or
secured to the end of the inlet tube A, and the water is propelled in a horizontal
direction into the dispersing or pulverizing grid D in a conical sheet so that its
outer edge may be pulverized or broken up as before specified. In this arrange-
ment the outlet tubes I are divided by the conoid or prism L to direct the current
of humidified air in each direction. The air inlet tube A. may be open to the room
or pass through the wall A' to the outside of the building to supply fresh
atmospheric air.
This apparatus operates as follows:-Water is admitted through the pipe F
and filter G to the pipe F¹, from whence the propelling nozzle C throws it in a
conical sheet into the dispersing grid D, with the effect that the outer edge of the
water is pulverized or broken up into a fine spray, the finer particles of which unites
with and passes away with the atmospheric air drawn through the tube A without
materially reducing the efficiency of the propelling power of the machine. The
tube A may be supplied with air from the room in which the apparatus is located,
so as to be continually treating the same over and over again, or one or both ends
of the air tube A may be carried to the outside of the building for the purpose of
receiving and delivering a fresh supply of humid air. Water that is not broken
up sufficiently fine to pass away with the air drops to the bottom of the trays I or
the dish A and passes through the perforated bottom of the conoid or prism L and
away by the outlet pipe H to the tank from which the pump draws or otherwise.
The bottom of the distributing trays or outlets I are inclined as shown to ensure
of water that drops therein from the humidified air returning to the outlet
pipe H.
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. In apparatus for bumidifying air the method of pronelling water in a conical

page_text: will be pulverized or broken up into a spray sufficiently fine to unite and pass away
with the air drawn through the apparatus, substantially as described.
2. Apparatus for humidifying air consisting of the inlet or inlets A, casing or
cylinder B, adjustable propelling nozzle C, water pipe F', dispersing grid D, conoid
or prism L, return water pipe H, and the outlets I with or without the separating
plates or regulators E, substantially as described.
3. In combination with apparatus for humidifying air the particular construction
of the water filter G, substantially as and for the purpose specified.
4. The respective combinations, constructions, and arrangements of parts composing
the improved humidifying apparatus as herein before described aud as illustrated in
the annexed drawings.
