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 :-
T
This invention relates to improvements in humidifiers for moistening or saturating
air in mills, weaving sheds, factories, and other buildings, and consists of an
improved water dispersing nozzle and the manner of constructing the eduction
vanes or outlets. My invention in connection with the dispersing nozzle consists
in placing before the orifice, through which water passes, a pin which divides the
current into a very large cone shaped spray, which, when placed in the cylindrical
casing of the humidifier, induces a current of air through it, which is washed and
moistened by coming in contact with the particles of water, thereby issuing cool or
warm according to the temperature of the water. My improved dispersing nozzle
consists in an adjustable projecting pin disposed in front of the orifice, the said pin
being of a diameter equal to the diameter of the outlet of the jet, and having a
flat face at right angles with the current of water issuing from the jet. The other
part of this invention relates to the form of the eduction vanes or outlets for the
purpose of further breaking up the particles of water as the same issues from the
humidifier.
Fig. 1 is a sectional elevation of my improved dispersing nozzle.
Fig. 2 is a sectional plan through line A. B.
Fig. 3 is an outside elevation of Fig. 1, and
Fig. 4 is a part sectional and outside elevation of a humidifier with my
improvements applied.
C is the casing or cylinder of the humidifier; D the water inlet; E the filter ;
F water return pipe, and G the distributing tray or outlet from the apparatus.
The water dispersing nozzle consists of the body H coupled to the filter E by the
pipe I and the nut J. The body H of the dispersing nozzle is provided internally
with the stand pipe K which leads to the outlet Z of the nozzle. Between the
inner wall of the body H and the outer wall of the stand pipe K is fixed the
metallic filter L consisting of perforated gauze; the upper and lower ends being
held in position by the rings M to form a tight joint to prevent sediment that may
accumulate in the cavity N passing under same. The upper end of the body H is
enclosed by the cap or cover O screwed thereon, the joint being effected by the
pliable ring P. The underside of the body H is provided with the screwed stem R
on which is mounted the arm S, which is secured thereto by means of the nut T ;
the lower end of the latter forming the outlet Z of the nozzle. In the arm S is
mounted the adjustable projecting pin V secured by the screw U. The pin V is,
by preference, of a diameter equal to the diameter of the outlet of the nozzle Ź
with a flat face at right angles with the current of water issuing from the said
nozzle or jet. This particular size and form of pin V splits up the water issuing
from the nozzle or jet Z to a degree of fineness which has never been attained
hitherto by jet of this character having only a single stream of water.
I would
have it understood that I do not limit myself to the diameter of the pin V, or in
the flatness of the face, as a variation in these points may take place without
destroying its complete usefulness, but the effect is not so good as when the said
pin V is of equal diameter to the outlet of the nozzle Z. An important part of
this invention is that the sharp edge of the flat face on the outer diameter of the
pin V meets the outer diameter of the jet of water at its smallest diameter, and

page_text: close up to the mouth of the jet Z where the velocity is the greatest. In all other
jets where a projecting edge has been presented to the water current it has been of
a much larger diameter than the orifice of the jet Z, and the water has been divided
in the centre and expanded before being split up. Water is supplied to the body H
by the pipe I into the cavity N and through the perforated metallic filter L, and
rises up the outside of the stand pipe K and flows down the centre of same to the
nozzle or jet Z. In the distributing tray or outlet G attached to the lower end of
the casing or cylinder C I mount the angular deflectors W for the purpose of
further breaking up the spray and arresting surplus water in its outlet from the
humidifier; the surplus water Howing down the inclined bottom of the distributing
tray G to the water return or outlet pipe F. The angular deflectors W are
secured in any convenient manner to the sides or frames X, which may be made in
a complete ring, in halves, or other segments for ready removal if desired.
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 combination with apparatus for humidifing air and the nozzle Z for
discharging water therein, the use of the adjustable pin V of equal diameter to
the diameter of the orifice or outlet Z of the nozzle and provided with a flat upper
surface with sharp edges at right angles to the current of the flow of the water to
meet the outer diameter of the jet of water at its smallest diameter and fixed close
up to the mouth of the jet where the velocity is the greatest, substantially as
described.
2. In combination with the casing or cylinder C and the distributing tray or
outlet G, the use of the angular deflectors W, substantially as described and for
the purpose specified.
3. The combination, construction, and arrangement of parts composing the
improved humidifying apparatus as hereinbefore described and as illustrated in the
annexed drawings.
