IMPROVED APPARATUS FOR CONVERTING LIQUIDS INTO SPRAY FOR VENTILATING PURPOSES
Year: 1884

page_text: I CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent, do hereby
declare the nature of the said Invention for "IMPROVED APPARATUS FOR
CONVERTING LIQUIDS INTO SPRAY FOR VENTILATING PURPOSES" and in what
mauner the same is to be performed to be particularly described in and by the
following statement:-
This Invention relates to improved apparatus for converting water and other
liquids into spray to be employed in combination with air blast or ventilating
apparatus for moistening the air in enclosed or partly enclosed spaces.
Fig. 1 of the accompanying Drawings shews a side view of the apparatus, Fig. 2
a plan of the jet pipes without the spraying discs or plates, Fig. a plan of the
complete apparatus.
Figs. 4 and 5 shew a vertical section and plan of a modified arrangement in which
the jets are arranged on an annular supply pipe, while the spraying discs are
replaced by a trough shaped ring. Figs. 6 and 7 shew the arrangement of the jets
on a rectangular system of supply pipes. Fig. 8 shews a curved form of the
supply pipes. Fig. 9 shews the application of the spraying apparatus in
combination with an air propeller in a ventilating shaft; Fig. 10 shews the
spraying apparatus combined with a blowing cylinder and Fig. 11 shews the
combination thereof with an ordinary ventilating fan.
The apparatus shewn at Figs. 1, 2 and 3 consists of a branched arrangement of
supply pipes a on which are fixed cocks b having, at their upper ends, nozzles with
very small holes; in place of cocks, simple nozzles may be used.
The liquid supplied under pressure at c issues in very fine jets from the cocks or
nozzles b, and impinges against the convex discs d, suspended from a framing e.
The curvature of the discs d is optional, but it is advantageous to make it
approximately parabolical, in order to effectually convert the jet into very fine
pray or mist.
If this apparatus be placed over the discharge opening of a fan or blowing
machine, such as shewn at Figs. 10 and 11, or other device for producing a current

page_text: of nir, such as the helical air propeller indicated in dotted lines in Fig. 9, the air
blast will carry the fine spray or mist along with it into the locality in which the
air requires to be moistened.
In place of the separate curved discs for each jet, may be employed a
continuous convex ring, such as shewn at d¹, Figs. 4 and 5, the cocks or nozzles b¹
being in this case arranged on a ring shaped supply pipe a', corresponding.in
diameter to that of the ring . The latter is carried by supports e' at the requisito
height above the nozzles for causing the liquid jet to be effectually converted into
fine spray on impinging thereon. In the arrangements shewn at Figs. 6 and 7, the
pipes a² as also the spraying plates are of rectangular form, two or more
thereof being arranged one within the other.
With the curved arrangement of supply pipe a³, Fig. 8, may be used either
separate spraying discs, as at Fig. 1, or a continuous spraying plate having a
configuration similar to that of the pipe, or there may be two concentric ring
shaped spraying plates corresponding respectively to the nozzles at the outer
curvatures and those at the inner curvatures. In all the above cases it is to be
understood that the spray produced is to be used in combination with an air blast
or a current of air with which it becomes intimately mixed and is thereby carried
into the locality to be ventilated with moist air; and it is of advantage to place
the apparatus directly over the discharge opening of a suitable blowing machine or
fan, as shewn at Figs. 10 and 11, or over the orifice of an air flue leading from such
blowing apparatus, so that the spray is brought in contact with the air current
while this is still concentrated and of its full force. Steam ejectors may also be
used for producing the blast in combination with this spraying apparatus.
-By-the-above described-means, the liquid, whether it be water or a chemical
solution, will be uniformly distributed in the form of spray or mist throughout the
locality to be ventilated, and the subdivision thereof being so fine, and its
admixture with the air so perfect that the formation of drops is effectually avoided,
the air being rendered uniformly moist throughout the locality, which is of great
importance, for instance, in spinning mills for preventing the breaking of the
fine threads. The apparatus is also applicable with great advantage for medicinal
purposes, any desired substance such as disinfectants, or substances to be inhaled,
such as sea water, mineral waters, and the like, being mixed with the water supply
that is converted into spray, and thus supplied to the air of the sick room.
Having thus described the nature of this Invention and in what manner the
same is to be performed, I claim :-
First: The construction of apparatus for converting liquids into fino spray or
mist for ventilating purposes, wherein fine jets of liquids are made to impinge upon
discs or plates so as to be converted into fine spray or mist which is at once
mingled with a blast or current of air, which carries it into the locality to bo
supplied with moistened air.
Second: The construction of apparatus herein described. with reference to
Figs. 1, 2, and 3 of the Drawings, consisting of a branch supply pipe a having cocks
or nozzles b, the fine jets of liquid issuing from which are made to impinge against
the convex plates d so as to be converted into spray thereby.
Third: The construction of spraying apparatus herein described with reference
Fig. 3 and 4 of the Drawings consisting of the annular supply pipe with
cocks or nozzles b' the jets from which impinge against an annular convex or flab
plato d'
Fourth The modified construction of spraying apparatus, with rectangular
supply pipes and spraying plates herein described with reference to Figs. 6 and 7
of the Drawings.
Fifth The modified construction of spraying apparatus with curved supply pipe
and either separate or continuous curved or circular spraying herein described with
Common to thing of the Drawings

page_text: Sixth: The combined arrangements of spraying apparatus such as is referred to
in the preceding claims with apparatus for producing blasts or currents of air
substantially as herein described
