COMPLETE SPECIFICATION.
Improvements in Water-spraying Apparatus for Moistening Air.
I, ANDREA MATOSSI, of Corso Brescia, 9 and 11, Turin, in the Kingdom of
Italy, Manufacturer, do hereby declare the nature of this invention, and in
what manner the same is to be performed, to be particularly described and as-
certained in and by the following statement, and accompanying drawings, that
is to say:
The present invention relates to apparatus for pulverizing water injected
under pressure, in order to moisten or humidify the surrounding air in weaving
sheds and the like; and it has for its object certain improvements, one part of
which renders the action of the pulverizing injectors adjustable as desired, and
much more effective, whilst the other part insures the better pulverization of the
water, and cleaning of the injector, than has been possible in apparatus of the
kinds heretofore known and used.
The accompanying drawing is in illustration of my invention.
Figure 1 being a general view (in vertical elevation partly in section) of the
complete apparatus constructed according to the present invention; and
Figure 2 shows (on a larger scale) a vertical elevation, partly in section, of
the improved injector.
The general form of the apparatus being that illustrated in Figure 1 (which corre-
sponds very nearly with the form most commonly adopted) the first part of the
present improvements consists in making the lower dish C, (which serves to
receive the drops of water which are not sufficiently pulverized) and is arranged
under the conoidal refracting surface e against which the jet of water is directed,
not as in the apparatus generally used fixed permanently to the body of the
apparatus, but connected to the latter by a sufficient number of bolts b round the
outer edge. It is thus moveable and adjustable vertically as desired, and conse-
quently allows the regulation of the pulverization of the water, and the discharge
of the latter into the surrounding air, in a more less finely divided state. It is
also possible the pressure of the water which is supplied being constant-to
give the desired humidity to the surrounding air, diminishing it or increasing
it by simply raising or lowering respectively the dish described above in relation
to the body of the apparatus, thus diminishing or increasing the annular dis-
charge orifice between the edge of the said dish and that of the base of the body
of the apparatus.
If this variation in the position of the dish be made uniformly round its entire
circumference, the humidity or moistening will also he varied equally on all
sides; but if it is desired that the humidity should be greater on one side of the
shed or room than on the other it is sufficient to adjust the dish so that it is
somewhat lower on that side. which is rendered easy by the simple manipulation
of the bolts b. which are made sufficiently long for the purpose. The present in-
vention therefore, affords two real and very important advantages which cannot be
obtained by the apparatus heretofore known.

page_text: The second part of my present improvements has for its object a greater
effectiveness and certainty in the pulverization of the water and in cleaning the
orifice of the jet; and it consists in a novel construction of the parts of the
pulverizer P (Figure 2). The latter is composed of the body p, upon which are
screwed on one side the pipe p' for admitting water under pressure, and on the
other the arm 2, to which is attached the fixed end of a helical spring r the other
end of which is hooked to the end of the lever L. A weight may, if desired, be
used instead of the spring. The lever is pivotted at 3 upon a support s carried
by the pipe p', and it also carries a pin 12 to which the moveable spindle p of
the pulverizer is connected, and, finally, it can be moved, when necessary, and
in any required manner, by its free end.. The spindlet passes through a
stuffing-box e into the interior of p, and is used to close the hole o (which is of
considerable relative diameter) at the bottom of p. with its lower end t', which
serves as a valve upon the seat through which the hole o is made. Upon the outer
surface of the valve are formed several radial straight or curved grooves d
for the ejection in numerous finely-divided streams, of the water admitted from
p into the body by means of a helicoidal groove h. The combination of the
conducting and directing grooves and produces in itself a very effective
pulverization of the water, which is afterwards increased and rendered perfect
by the breaking and refraction of the jet against the conoidal surface C and on the
curved edges at u and at the bottom of the body of the apparatus, (Figure 1).
These latter have also served to retain any drops of water not completely pul-
verized, or becoming deposited on the inner walls of the apparatus, making them
flow into the bottom of the dish C, whence they are discharged by the central
pipe a. The pipe, which is provided with a valve for cutting off the supply,
conducts the water to the pipe pl which admits it into the pulverizer. The latter
is carried in the apparatus and is fixed there by screws and double nuts m on p
and non pl in the usual manner. Its method of construction evidently allows it
to be adapted to any existing apparatus of every kind.
It is absolutely impossible that the hole o should become obstructed, for its
section is much smaller than that of all the grooves d together. And, if one of
the latter should become obstructed, it is only necessary to move the lever L by
pulling it down a few times with a simple hooked stick or the like, or a small
chain applied to its free end; at each movement the spindle is raised. and lifts
the head or valve t¹ from its seat, allowing a large current of water to pass under
strong pressure, which washes and cleans thoroughly the grooves , and easily
and quickly carries away all deposit.
The present improvements render the apparatus to which it is applied
greatly superior to those ordinarily used. In the first place, by its means the
pulverization of the water, and the distribution of moisture, can be regulated and
adjusted either evenly or unevenly as desired round the apparatus. Moreover,
the cleaning of the pulverizer is much easier and more certain than in the
systems heretofore adopted, and which may be classified as follows; 1-By the
use of an instrument or point for cleaning; 2.-By a single small hole;
3. By several very small holes. In the first case, the cleaning instrument is 4
very often broken in using it, especially if it meets any hard substance, a grain
of sand, for instance. In the second case, and still more in the third case, ob-
struction is always more readily produced, whilst it is more difficult to remove,
for it is necessary in this case to take to pieces the entire apparatus at very great
inconvenience; the cost of the workman entrusted with keeping the apparatus 5
in order, there always being a number of the latter in a single factory; of the
stoppage, sometimes for a considerable time, of the machines under the apparatus
which is being cleaned, since a ladder or equivalent means are required to get at
it of irregularity in the production from the surrounding machines on account
of the absence of the moisture round the apparatus which is being set right. 5
All these objections are evidently overcome when apparatus provided with the
present improvements is made use of.

page_text: Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:―
In injecting and water-pulverizing apparatus for moistening the surrounding
air, the pulverizer consisting of a moveable valve, having straight or curved
radial grooves arranged above a hole of sufficient diameter in the bottom of the
injection chamber into which the water under pressure is introduced by a
helicoidal groove; a dish below the bottom of the apparatus to receive the water
not sufficiently pulverized, the dish being moveable and adjustable vertically in
relation to the body of the apparatus, and capable of being arranged either parallel
with, or inclined to, the lower edge of the latter; so that the most perfect pulveri-
zation of the water is obtained, with a greater or less distribution of the pul-
verized water through the annular opening between the edge of the dish and the
body of the apparatus, and consequently a humidity greater or less in degree in
the shed or room; a distribution, either uniform or unequal, of the pulverized
water, and consequently a humidity varying to a corresponding extent in the
different parts of the shed or room; and finally, an absolutely easy and certain
method of cleaning the pulverizer without any objectionable influence upon the
work of the machines in the neighbourhood of the apparatus; substantially as
described and illustrated.
