Improvements in and relating to Apparatus for Moistening the Air
in Spinning and Weaving Mills and other places.
I, DESIRE VISTE and ETIENNE Daw, both of 7, Rue de Bapaume, Lille (Nord),
in the Republic of France, Engineers, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to an apparatus for ventilating and rendering moist the
air of spinning and weaving mills, that is to say it is intended to produce a hydro-
metric degree of artificial moisture according to the requirements of the different
branches of the textile industry and of all other more or less closely allied trades.
Our apparatus is preferably made in zine which is covered with a coat of enamel.
It consists of three principal parts; a cylindrical body, a water overflow or receiver,
and a pulveriser.
The apparatus is preferably suspended from the roof of the room or the like by
means of two rods which support the body by means of the lugs.
The water overflow or receiver is fixed to the body by means of vertical rods, in
such a manner as to leave between the said water receiver and the cylindrical body
sufficient space for the exit of the moistened air. Small spherically shaped nuts
permit a separation of the parts to be readily effected.
The cylindrical body comprises an external envelope and a central conical
vessel or truncated cone, the height of which is capable of regulation.
The external envelope is provided at its upper part with a perforated crown,
through which perforations the air is able to penetrate into the annular space left
between the inner and outer parts of the body. The conical or inner part is
intended to reduce the diameter of the jet produced by the pulveriser, located in
the axis of the apparatus. This conical part is, as already explained, capable of
regulation as to height, in such a manner as to permit the diameter of the jet of
spray to be reduced at will.
The mobility of the conical part in the vertical direction is assured by fixing
upon the internal surface of the envelope, upon generating lines, U-shaped slide-
ways, and, upon the external surface of the truncated cone, slides which remain
constantly engaged in the said slide ways. The slide ways are turned down hori-
zontally at their upper portion so as to form lugs, and the slides are continued
upwardly by screw threaded rods, which traverse these lugs and received winged
nuts. By screwing or unscrewing more or less these nuts, which have a fixed
bearing upon the lugs, the conical vessel is raised or lowered.
The water overflow or receiver is formed by a kind of basin, the conical bottom
of which serves to receive the surplus water, and is provided for this purpose, at
its lower portion, with a pipe, for running off such water. Within the overflow or
receiver rests an upwardly directed conical part, which constitutes the receiver
about half way up the cone is fixed a vertical annular flange, forming
proper;
baffle plate for the spray of water. In addition the cone has two crowns of
perforations through which the water is able to pass into the overflow or receiver.
From the lower edge of the external envelope and from the upper edge of the
a

page_text: basin or receiver, two truncated cones start, these being approximately parallel one
with the other and forming an annular channel through which the moistened air
may escape from the apparatus in an upwardly sloping direction.
The pulveriser arranged in the axis of the apparatus, is connected with the water
supply pipe. This pulveriser, which may readily be removed, comprises three
parts; a socket, a rod and a nozzle. The socket is connected with the supply pipe
by means of a branch pipe on the socket. The lower end of the rod forms a screw
having one or more threads serving to divide the water current into jets having a
rapid gyratory-motion upon their reaching the nozzle. The upper portion of the
rod forms a stopper for the socket and is formed with wings which facilitate
screwing and unscrewing. The nozzle screwed upon the lower extremity of the
socket, forms a cavity having either a flat or rounded bottom and provided at the
centre with a small opening, through which the water escapes into the conical part
of the cylindrical body.
As regards the construction, we reserve to ourselves the right to simplify it by
fixing the conical part rigidly to the interior of the envelope. In the same
manner, we may arrange a lid or covering above the apparatus, but in such a
manner as to permit air to enter freely and so as not to interfere with the manipu-
lation of the pulveriser. The nozzle of this latter may, as already stated, be
spherical, parabolic, or flat in shape.

Improvements in and relating to Apparatus for Moistening the Air
in Spinning and Weaving Mills and other places.
We, DESIRE VISTE and ETIENNE DAW, both of 7, Rue de Bapaume, Lille (Nord),
in the Republic of France, Engineers, do hereby declare the nature of this inven
tion 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 an apparatus for ventilating and rendering moist the
air of spinning and weaving mills, that is to say it is intended to produce a hygro-
metric degree of artificial moisture according to the requirements of the different
branches of the textile industry and of all other more or less closely allied trades.
Our apparatus presents none of the disadvantages of similar appliances at present
in use; it is simple in construction and practical in its operation.
In the accompanying drawing we have represented, by way of example, one
constructional form incorporating the distinctive characteristics of our invention.
Figure 1 is an external elevation of the apparatus.
Figure 2 is a vertical section taken upon the line 1-2 of Figure 1.
Figure 3 is a longitudinal section through the pulveriser.
Figure 4 shews different forms of joint or nozzle for the pulverizer.
Figures 5 and 6 represent, upon a larger scale, by means of a vertical section
and a horizontal section respectively, the method of connecting the external
cylindrical envelope of the apparatus and the central conical part.
Our apparatus is preferably made of zinc which is covered with a coat of enamel.
It consists of three principal parts; a cylindrical body a a water overflow or
receiver b and a pulveriser c.
The apparatus is preferably suspended from the ceiling of the room or the like

page_text: by means of two vertical rods n which support the body a by means of lugs or
brackets n¹.
The water overflow or receiver b is fixed to the body a by means of vertical rods f,
in such a manner as to leave, between the parts b and a, sufficient space for the
exit of the moistened air. Small spherically shaped nuts f¹ permit a separation
of the parts to be readily effected. The cylindrical body consists of an external
envelope a and a central conical vessel or truncated cone a', the height of which is
adapted to be regulated.
The external envelope a is provided at its upper portion with a crown of perfora-
tions a², through which the air is able to penetrate into the annular space left
between the external envelope a and the conical vessel a¹. The conical vessel a¹
is intended to reduce the diameter of the jet produced by the pulveriser c arranged
in the axis of the apparatus. This conical part a' is, as already explained, capable
of regulation as to height in such a manner as to render it possible to reduce the
diameter of the jet of spray at will.
The mobility of the internal conical part a¹ in the vertical direction is assured by
fixing upon the internal surface of the envelope a, upon generating lines, U-shaped
slide ways e, and upon the external surface of the truncated cone a', slides i which
remain constantly engaged in the slide ways, as clearly shown in Figure 5 and 6
of the drawing.
The slide ways e are turned down horizontally at their upper portion so as to
form lugs e, and the slides d are continued upwardly by the screw-threaded
rods which pass through these lugs and receive thumb nuts g. By screwing or
unscrewing more or less the nuts g which have a fixed bearing upon the lugs e',
the conical part a' is raised or lowered.
The water overflow or receiver is formed by a kind of basin b the conical bottom
of which serves to receive the surplus water and which is provided, for this purpose,
at its lower point with a pipe 61 for running-off any such water. Within the
overflow or receiver rests a conical part 2 which forms the receiver
proper; about
half way up the cone is fixed upon it a vertical annular flange i forming a baffle
for the jet of water. In addition, the cone has two crowns of perforations o through
which the water is able to pass into the overflow or receiver.
From the lower edge of the external envelope and from the upper edge of the
basin b, proceed two truncated cones h and k which are approximately parallel
one with the other and form an annular channel through which the moistened air
may escape from the apparatus in an upwardly inclined direction.
The
The pulveriser c (Figures 3 and 4) arranged as shewn in the axis of the apparatus
is connected with the water supply pipe . This pulveriser, which may be readily
removed, consists of three parts; the socket e, the rod t and the nozzle m.
socket is connected with the supply pipe by means of the branch pipe c. The
lower end of the rod t forms a screw having one or more threads t¹ (preferably two
threads) intended to separate the current of water into jets having a rapid gyratory
motion upon their reaching the nozzle m. The upper portion of the rod t forms a
stopper or plug for the socket c and is formed with a thumb nut 2 which facilitates
screwing and unscrewing. The nozzle m screwed upon the lower extremity of
the socket c, forms a cavity having either a flat or rounded bottom (Figure 4) and
provided at the centre with a small aperture m¹ through which the water escapes
into the cylindrical body.
The apparatus acts in the following manner: The water under pressure which
arrives at passes through the pipe c' into the socket e of the pulveriser and is
projected against the conical rod t. The pressure forces the water to enter the
helicoidal conduits t' where it assumes a rapid gyratory motion, the jets are broken
up within the cavity of the part m, and the completely pulverised water escapes
through the aperture m' arranged in the axis of the apparatus.
The jet of water acts in the manner of an ordinary injector and sucks air into
the apparatus through the upper end which is open and through the perforations a
distributed around the envelope of the apparatus. A portion of this air, after

page_text: becoming mixed with water, that is to say after becoming moistened, escapes from
the apparatus through the annular opening; the water falling with force upon
the cone 62 and the flange i, is broken up into a mist or very fine spray and escapes
with the air carried along, whilst the surplus water runs down the cone and drops
through the perforations o into the receiver b from which it runs off through the
pipe 6. The vertical flange i of the receiver especially intended to break and stop
the water which would have a tendency to escape with the air.
The dry air entering at the top of the apparatus does not all mix with the water
to become moistened; a large part of this air passing into the circular space
between the parts a and a¹; this dry air being lighter than the moist air, and
mixing with such moistened air at its outlet from the annular channel between h
and causes a powerful ventilating action and effects, in a uniform manner, the
exit of the moist air from the apparatus.
Instead of taking air directly from the room or the like, we may take it from
without, in such a manner that whilst moistening this pure air, the vitiated air
of the room is renewed.
As regards the construction of our apparatus, we may, for the sake of simplicity,
fix the conical part in an invariable manner within the envelope a. In the
same way, a lid or covering may be arranged above the apparatus, but in such a
manner as to leave the admission of air free and not to hinder the manipulation of
the pulveriser. The nozzle of this latter may as already stated, be made of spherical
or parabolic form or may have a flat bottom, as shewn in Figure 4 of the drawing.
Finally we would point out that although our apparatus is intended more
especially for the textile industries, it is also extremely useful where the manu-
facture of paper, printing upon calicoes, fabrics or the like, the dyeing or dressing
of stuffs and numerous other manufactures are carried on.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. An air moistening apparatus comprising a pulveriser immovably arranged in
the axis of the apparatus, a part having the form of a truncated cone, the height of
which with respect to the issue of the jet leaving the pulveriser is capable of
regulation, an external envelope concentric with the truncated cone and forming
with this latter an annular space in which is set up a current of dry air when
mingles intimately with the moist air before leaving the apparatus, and a conical
receiver against which the jet is projected in such a manner as to transform the
water into a mist or very finely divided spray which mixes with the air drawn in
by the jet of the pulveriser, substantially as above described and represented in
the accompanying drawing.
the
2. In the air moistening apparatus described in Claim 1, a pulveriser the conical
rod of which forms with a socket c an annular space within which
water arrives under pressure, and which space terminates in one
or more helicodial passages dividing the water into jets having a rapid
gyratory motion, which jets are broken up within the cavity of a
nozzle of appropriate form and escape in a sprayed form through a small aperture
formed at the centre of this nozzle substantially as described above and represented
in Figure 3 of the accompanying drawing.
3. The air moistening apparatus constructed and arranged substantially as above
described and represented in the accompanying drawing.
