improvements in Spray Jets for Liquids.
We, THOMAS EDWARD WILSON, of No. 3, Rue de la Digue, Lille, France, Engineer,
and PAUL KESTNER, of No. 40, Boulevard Vauban, Lille, 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:-
Our said invention relates to improvements in the construction of jets for converting
liquids into spray, for watering purposes, cooling liquids by subjecting them in a finely
comminuted form to the action of air, cooling or humidifying air, precipitating smoke
fumes or dust, producing a circulation of air, or for other purposes for which spray
producing devices are useful.
Referring to the accompanying drawings which illustrate our said invention
Figure 1 is a sectional elevation and
Figure 2 is a sectional plan of one form of our said invention.
Figure 3 is a Fectional elevation and
Figure 4 is its corresponding sectional plan of another form of our said invention.
In Fig. 1A is the jet chamber into which the liquid is admitted along the passage 1
tangentially from an inner chamber B cominunicating with the supply pipe Y.
This
tangential admission of the liquid into the jet chamber induces a centrifugal action
and causes the liquid to escape from the jet X in the form of spray or rain. A second
tangential chamber as indicated by dotted lines may be provided symmetrically
with the passage or several such tangential passages inay be provided. The jet
chamber A may be made of any shape provided it has an axial orifice X.
The form shown in Figs. 1 and 2 is suitable for breaking up liquids into the form
of rain for example for the purpose of cooling water.
The form shown in Figs. 3 and 4 is more particularly suitable for small jets for
converting the liquid into the very finest spray. In this form the jet chamber A pro-
vided at its base with a tangential admission passage. An axial orifice X is
provided for the exit of the liquid. The lower chamber B which communicates with
the supply pipe Y contains a sieve or strainer D for keeping back any solid matter
which might stop up the orifice of the jet. As in the case of the forin first described
there may be a second tangential admission passage as indicated in dotted lines at ³
or there may be several such.
Either of the two forms of our said invention as above described may be used to
form combinations of superposed jets, for example in the form shown in Fig. 1 the
chamber B may communicate with a pipe passing concentrically through the orifice X
and feeding a second jet which in turn inay feed a third one.
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. A liquid spraying jet having a jet chamber fed by one or more tangential

page_text: 2. A spray jet for liquids having in combination a jet chamber A an internal
chamber B and one or more tangential passages such as r connecting the two
chambers substantially as hereinbefore described and shown with reference to Figs. 1
and 2 of the accompanying drawings.
3. A spray jet for liquids consisting of a jet chamber A in combination with an
outer chamber B₁ and one or more tangential passages 2 connecting the two chambers
substantially as hereinbefore described and shown with reference to Figs. 3 and 4 of
the accompanying drawings.
4. In combination with a tangentially fed jet chamber such as described with
reference to Figs. 3 and 4 a sieve or strainer D substantially as and for the purpose 1
set forth and shown.
