Improvements in Nozzles for Spraying Water and other Liquids.
We, LAWRENCE. FARRAR GJERS, of Woodlands Road, and JOSEPH HUTCHINSON
HARRISON, of 2, Exchance Place, both in Middlesbrough-on-Tees, in the County
of York, Engineers, 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..
This invention relates to a nozzle through which water or other liquid can
be projected under pressure in such a way that it is broken up into minute
particles or spray for the purpose of cooling it or for other purposes where a
spray is desired
The object of our invention is to provide a nozzle with two or more openings
or jets for the projection of water or other liquid arranged at such angles with
each other that the streams of water or other liquid issuing from them impinge
upon each other at one and the same point, such streams being thereby broken
up into minute particles or spray Hot water or other liquid thus formed into
spray and thereby exposed in a finely divided condition to the atmosphere will
be cooled
And in order that our invention may be clearly understood and readily carried
into effect, we will proceed to describe the same with reference to the accom-
panying diawing, in which Fig 1 is a plan view, and Fig. 2 a cross section of
a form of nozzle constructed for the purpose of this invention Fig 3 18 an

In the drawing the nozzle takes the form of an inverted cone a in the bollow
part of which are holes or openings 6 baranged in such a way that the jets of
water on other liquid forced through them impinge on one another with such
force that the water or other liquid is broken up into fine drops or spray
nozzlo may have two, three of any greater number of openings or jets, but
we prefer two only as giving the best results and the angle at which the streams
from such openings or jets stuke each other may be varied to suit the form
which the volume of spray is deaned to take, for instance a smaller angle gives
a higher spray whilst a large angle gives a lower and broader spray The
nozzle is provided with a screw thread c for fixing into a suitable pipe such as d
though which the hot water or other liquid is projected under pressure, the
top part e being cunted to allow of its being turned with a spanner. The inverted
cone a, is pierced by two round holes beach carefully rounded at the underside
to pass the water or other liquid more freely. These holes are both centred on
the same centie line of the nozzle as shown in plan in Fig 1 and are at equal
distances from the point of the inverted cone a as shown in Fig 2, that is aie
placed directly opposite each other, and are so drilled that the centre line through
Pach cuts tuo vertical centie line of the nozzle at the same point making with
it an angle of about 45° These holes may be made rectangular as well as
round o be otherwise varied in shape.
It is found in practice that by using two holes only the water is better bioken
up and they can be made larger than if three or four holes were used, thereby
not being so liable to get choked up by any dirt or gut in the water, a laigei
number of holes being in every case less effective for the purpose of our inven-
tion than a smaller number of such holes.
But we do not restrict ourselves to the use of a cone as shown in the drawing,
and which is to be taken as representative only of what is suitable for the
purpose, as for instance the object of our invention could be attained by jets
projected at the proper angle to get the requisite impingement without regard
to the exact shape or contour of the nozzle from which they are so projected.”
Having now particularly descubed and ascertamed the nature of our sand
invention and in what manner the same is to be performed, we declare that what
we claim 18
The means fe spraving water and other liquids by which the said water or
other liquid is projected under pressure through holes or jets at such angles
with each other that the streams impinge upon one another and are broken up
into minute particles or spray, substantially as and for the purpose herein before
described with reference to the accompanying drawing
