ALFRED JAMES EADE 4 Gloucester Place Worthing Machinist and Gasfitter and
J. AMOS EADE of Edenbridge Kent Smith and Machinist do hereby declare the
nature of this invention to be as follows:-
Our invention consists in the constructing of a Water-Jet for spraying purposes
and is carried out in the following manner.
A hollow cone is provided constructed out of brass or other suitable material the
said hollow cone being open at its top & bottom for the passage of the water when
fixed on the tap or supply pipe-In the interior of the cone and commencing at the
angle formed by the sudden tapering of the cone toward the top are two or more
small grooves which terminate at the aperture at the top of the cone-These grooves
in the interior of the cone above referred to have the effect of producing as many
distinct and separate sprays of water as there may be grooves-When a spray for
long distances is required the angle of the interior of the cone which contains the
grooves may be made more or less acute as may be required.

page_text: An improved water Jet.
We, ALFRED JAMES EADE of 4 Gloucester Place Worthing Machinist and Gas-
fitter and AMOS EADE of Edenbridge Kent, Smith and Machinist, 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 water-jets or nozzles for spraying purposes the peculiar
feature consisting in so constructing them that although only provided with one
orifice the water issuing therefrom under sufficient pressure will be broken up into
spray such as has hitherto only been obtainable by means of a rose jet.
In the accompanying drawings Fig. 1 is an enlarged view in elevation of a jet with
a portion cut away to show the interior and Fig. 2 is a transverse section taken
through the line - on Fig. 1.
Fig. 3 shows a slightly modified form of jet and Fig. 4. is a cross section through
line w―w.
Fig. 5 also shows a modification.
The invention consists principally in contracting the nozzle until it forms a hollow
cone A truncated a short distance below the apex thus leaving the outlet orifice a.
When the nozzle made in the form shown in Fig. 1 the metal around the orifice is
purposely left sharp. The nozzle shown in Fig. 3 differs from that in Fig. 1 in
respect to the orifice which is in reality a short tube having grooves & cut at intervals
around its circumference the grooves being carried to the extreme edge of the orifice
so that at the points where the grooves end the orifice is as sharp as in Fig. 1. As
the water passes through the nozzle it is split up by the grooves into separate jets
which converge towards the outlet where they mect and the impact of the particles
causes the jets to be broken up and diffused as spray. The number of grooves is
immaterial provided each current is met by one from the opposite side of the nozzle,
it is important however that they should be continued to the outer edge of the orifice
as if the latter is left perfectly tubular for even a very short distance the particles of
water tend to issue parallel with each other and thus combine to form a single jet. Wo
can increase the number of grooves indefinitely until we obtain a practically plain
orifice such as is shown in Fig. 1 and this is a convenient form in which to manu-
facture the jet. In this case the interior of the cone is made elliptical at seen in
Fig. 2 and the sides c-c being narrowed exercise a directive influence on the
water similar to that exercised by the grooves b in the jet shown in Figs. 3 and 4.
To reduce the wearing action of the water the nozzle is prolonged beyond the actual
orifice a forming a countersunk recess. The nozzle might however terminate flush
with the orifice but the edge of the latter will be rendered too weak to resist the
wearing action of the water under pressure for any length of time. The jet shown
in Fig. 5 differs from those previously described inasmuch as the nozzle is solid at the

page_text: end and has holes d perforated at intervals near the outer edge of the cone. The
water issues from these holes in a series of converging jets which meet as they issue
from the nozzle and are broken up into spray. As the hollow nozzles shown in
Figs. 1 and 3 give results very similar to the nozzle in Fig. 5 it may be assumed that
the particles directed by the converging sides of the cone pursue intersecting paths
after leaving the nozzle and are thus broken up into spray.
The angle of the hollow cone may be varied according to the purpose for which the
spray is required. A nozzle with an acute angle such as is shown in Fig. 1 gives a
longer jet of spray than one with an obtuse angle such as is shown in Fig. 3, the
latter jet however would cover a greater area.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is :-
1. A water nozzle tapering internally towards the delivery end and having grooves
such as 6 terminating at the outlet A substantially as described and illustrated in the
accompanying drawings.
2. A water nozzle in which the metal or other material surrounding the discharge
orifice is reduced to a sharp edge either by means of grooves such as b as in Figs. 3
and 4 or by the conical formation of the interior of the nozzle as in Fig. 1
substantially as described and illustrated in the drawings.
3. The distribution from a single orifice of a stream of water in the form of spray
by employing a nozzle which causes the particles of water to issue from the discharge
orifice in converging streams which meet beyond the orifice substantially as
described.
4. A water nozzle having holes such as d for the purpose of discharging con-
verging jets substantially as described and illustrated in Fig. 5 of the accompanying
drawings.
5. A water nozzle constructed substantially as and for the purpose described and
illustrated in the accompanying drawings.
