Improvements in Apparatus for Humidifying Air.
I, JOHN JAMES MANN, of 11, Boulevard des Italiens, Paris, France, Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to apparatus for humidifying air, the object being to
improve the action and construction of such apparatus.
My improved apparatus consists of a cylinder open at both ends as usual, within
which is a nozzle or jet throwing a fine spray against the inside of the cylinder
beneath which is a dish and a spreading cone dispersing the fine spray into the
room. The cylinder is formed or provided with a coned or trumpet mouth at its
lower end all round the bottom edge of which I form or fit a gutter which catches
any water running down the inside of the cylinder and its coned or trumpet
mouth end prevents such water from dripping from the edge of the
latter a pipe or duct, fish-backed on its inner side, carries off the water from this
gutter into the bottom of the dish. The lowest part of the dish forms a shallow
gutter around a vertical tube open at top and bottom and placed centrally in the
apparatus extending up through the apex of the spreading cone; and at the
lowest part of the dish is an escape pipe for the water collecting in or on the inner
surfaces of the apparatus or covering from the above named fish backed pipe or
duct.
The nozzle is arranged centrally in the cylinder immediately above the upper
end of the tube above described; it consists of a small barrel or case, or the like
having a small opening at its lower end and connected to a suitable supply of
water under pressure. Projecting for a short distance into this barrel or body is
a small spindle having at its upper end a head or shoulder of such a size as to
fit the aforesaid opening; this spindle is held by a suitable spring in a casing or
box beneath in such a position that a second shoulder on the spindle is just below
the opening in the nozzle, this last named shoulder causes the water issuing from
the nozzle to be broken up into spray.
The spindle below the spring box has a screw thread thereon, and a nut is pro-
vided to adjust the position of the shoulder below the orifice of the nozzle.
The spindle is further provided with a dome cone or other cover protecting the
upper end of the central open tube above named and preventing water from
falling thereon.
From the end of the spindle hangs a cord chain or equivalent device provided
with a suitable handle, and thus by pulling this handle the head of the spindle
can be brought down into the orifice of the nozzle which it exactly fits and thus
clear out dirt from the orifice. The head of the spindle may be further so elongated
that when the cord is pulled down, not only will the orifice be cleared of dirt but
the flow of water can be stopped altogether by hooking or fixing the handle or
cord when drawn down.

page_text: When the handle is released the spring will return the lower shoulder on the
spindle into place to form the spray.
I further propose in some cases by duplicating the shoulders and bodies of the
above nozzle (or by duplicating other jets in any known way) to form two sprays
in the cylinder the one below the other, and my invention consists in such cases in
providing an internal cylinder concentric with the ordinary cylinder and so
arranged therein that the lower spray impinges on the inside of this internal
cylinder.
The use of this internal cylinder prevents the formation of drops of water which
have hitherto diminished the utility of a double spray in one cylinder, and which I
have found are formed by the mingling or crossing of the sprays in the cylinder.
In the case of duplicating the nozzle above described I may pass the spindle
through a packing or stuffing box in the top of the lower nozzle.
A gutter will be provided round the lower edge of this internal cylinder whether
it is splayed out or not, to catch the water from both surfaces of the internal
cylinder.
In some cases I also splay outwards the lower end of the internal cylinder above
named to form a spreading cone for dispersing the upper spray, the inner spray
being dispersed by the usual cone on the dish beneath.
The upper spreading cone may form the mouth or outlet for the lower spray, or
the said cone may be at such distance above the flaring mouth of the lower spray
as to deliver the two sprays in more distinctly separate strata or planes having
unhumidified air between them, which can take up excess of moisture from either
spray.

Improvements in Apparatus for Humidifying Air.
I, JOHN JAMES MANN, of 11, Boulevard des Italiens, Paris, France, 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 relates to apparatus for humidifying air, the object being to
improve the action and construction of such apparatus."
The invention will be readily understood from the following description on
reference to the accompanying drawings the four figures of which illustrate in
sectional elevation various ways of carrying the said invention into practice.
My improved apparatus consists of a cylinder 6 open at both ends as usual,
within which is a nozzle or jet at a (see Fig. 1) throwing a fine spray shown by
the dotted line x against the inside of the cylinder beneath which is a dish
and a spreading cone c¹ dispersing the fine spray into the room. The cylinder b
is formed or provided with a coned or trumpet mouth 6* at its lower end, all round
the bottom edge of which I form or fit a gutter 6** which catches any water
running down the inside of the cylinder b and its coned or trumpet mouth 6, and
prevents such water from dripping from the edge of the latter, a pipe or duct d
fish-backed (ie. with a sharp edge) on its inner side, carries off the water from
this gutter into the bottom of the dish c. The lowest part of the dish c forms
a shallow gutter around a vertical tube 61 open at top and bottom and placed
centrally in the apparatus extending up through the apex of the spreading cone c¹ ;

page_text: and at the lowest part of the dish c is an escape pipe e for the water collecting
in or on the inner surfaces of the apparatus or covering and delivered from the
above named fish backed pipe or duct d.
The nozzle a is arranged centrally in the cylinder immediately above the
upper end of the tube 6' above described; it consists of a small barrel or case a,
or the like having a small opening at its lower end and connected to a suitable
supply of water under pressure. Projecting for a short distance into this barrel or
body a is a small spindle a¹ having at its upper end a head or shoulder a² of such
a size as to fit the aforesaid opening; this spindle a¹ is held by a suitable spring a
in a casing or box A beneath in such a position that a second shoulder a³ on the
spindle a is just below the opening in the nozzle a this last named shoulder a³
causes the water issuing from the nozzle a to be broken up into spray.
The spindle a¹ below the spring box A has a screw thread thereon, and a nut a³
or other suitable device is provided to insure the correct position of the shoulder a¹
below the orifice of the nozzle a.
The spindle a¹ is further provided with a dome a³ or cone or other cover pro-
tecting the upper end of the central open tube b¹ above named and preventing
water from falling thereinto.
From the end of the spindle hangs a cord as or chain or equivalent device pro-
vided with a suitable handle a', and thus by pulling this handle a the head a³
on the spindle a¹ can be brought down into the orifice of the nozzle a which it
exactly fits and thus clears out dirt from the orifice. The head a² of the
spindle a may be further so elongated as shown that when the cord is pulled
down, not only will the orifice be cleared of dirt but the flow of water can be
stopped altogether for any desired length of time by hooking or fixing down the
handle a or cord a when drawn down.
When the cord as or handle a is released the spring a will return the lower
shoulder 3 on the spindle a¹ into place to form the spray, the nut a³ or other
abutment ensuring the correct position of the said shoulder a³. The tube b¹ pro-
tects the cord as from the spray.
I further propose in some cases by duplicating the shoulders a² a³ and bodies a
of the above nozzle as seen at Figs. 2, 3 and 4 (or by duplicating other jets in
any known way) to form two sprays in the cylinder b the one below the other, as
shewn for example at xx, and my invention consists in such cases in providing an
internal cylinder 62 concentric with the ordinary cylinder b and so arranged therein
that one cone of spray, say the lower spray a¹, impinges on the inside of this
internal cylinder 68.
The use
of this internal cylinder 2 prevents the formation of drops
of water which have hitherto diminished the utility of a double spray in
one cylinder, and which I have found are formed by the mingling or crossing of
the sprays in the cylinder.
In the case of duplicating the nozzle above described I may pass the spindlo
through a packing or stuffing box a in the top of the lower nozzle.
In some cases I also splay outwards the lower end of the internal cylinder 63
as seen at Figs. 3 and 4 to form a spreading cone 63 for dispersing the upper
spray, the inner spray a¹ being dispersed by the usual cone c¹ on the dish c
beneath.
The upper spreading cone 63 may form the mouth or outlet for the lower spray
as seen at Fig. 3, or the said cone 63 may be at such distance above the flaring
mouth 4 of the lower spray so as to deliver the two sprays a¹ in more distinctly
separate strata or planes having unhumidified air between them, which can take
up excess of moisture from either spray.
A gutter f will be provided round the lower edge of the internal cylinder b²
whether it is splayed out or not, to catch the water from both surfaces of the
internal cylinder b³.
It is evident that the spray may be directed upwards if desired.

page_text: · 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:-
1. The combination of parts forming improved humidifying apparatus sub-
stantially as described with reference to Figs. 1, 2, 3 and 4 on the drawings
annexed.
2. The spraying device consisting of a nozzle or chamber in connection with a
supply of water under pressure the said nozzle or chamber having an opening at
the lower end into which extends a spindle provided with a head or shoulder
inside the chamber and a shoulder immediately beneath the opening held by a
spring in a suitable spring box in such a position as to give the desired degree of
fineness to the spray; a chain cord or the like being connected direct to the lower
end of the spindle substantially as and for the purposes herein before described.
3. The combination with a nozzle or nozzles emitting or forming two or more
separate sprays one beyond the other, of a casing provided with an internal
cylinder or cylinders or the like in such a manner that the upper spray impinges
on the casing and the lower spray or sprays upon the internal cylinder or cylinders
or vice versa, substantially as described.
