We, GEORGE ARTHUR GOYDER, Analytical Chemist, and the Honorable DAVID
MURRAY, Member of the Legislative Council, both of Adelaide, in the Province of
South Australia, do hereby declare the nature of this invention to be as follows:-
The object of our invention is to provide a simple implement for producing a liquid
spray for use in the following ways or purposes, amongst others:-1, in watering
gardens; 2, for fountains, revolving lawn waterers; 3, spray condensers for cylinders
of steam engines; 4, spray for chemical works; 5, insecticide spray; 6, shower bath;
7, scent spray; 8, light or heat jets; 9, and for any other purposes requiring a liquid
spray.
Our invention consists in an open pipe containing a "spiral director" so arranged
and grooved that any liquid introduced into the ingress end of the nozzle must pass
through the spiral grooves and so acquire a rotary motion which will cause it to issue
from the nozzle as a spray; the egress end of the nozzle being reduced in size unless
a coarse spray is required.
The nozzle may be either straight, curved or angled.
The large end of the nozzle may be either plain, notched, bulbous or screwed for
attachment to the supply pipe.
*
The spiral director" may be situated anywhere along the inside of the nozzle ;
and the grooves may be made either (1st) in the tube walls with a solid plug running
part of the length of the grooves, but with the grooves extending beyond the plug in
both directions; or (2ndly) the grooves are made in the plug which fits closely
in the nozzle.
"
The grooves of the "spiral director may be round, half round, square, angular or
of other convenient shape forming a screw, which may be of any pitch, and on the
principle of either the common or archimedian screw. The screw may consist of any
number of grooves.
The egress end of the nozzle may taper with a straight, convex or concave section,
and either in a gradual or sudden manner partly reentering.
The egress end of the nozzle may be made either in one piece with the rest of the
tube, or detachable, or as one or more detachable fittings provided with different sized

page_text: orifices; and these fittings may be screwed on suitable studs which may be further
provided on the nozzle.
Or the egress end may be part of a tube which screws or slides over the main tube,
so that the distance from the "spiral director" to the effluent orifice may be varied.
A filtering chamber may be provided where necessary between the nozzle and the
supply pipe.
The nozzle may be used in conjunction with hydraulic or mechanical pressure or
with a pump, syringe or reservoir.
The nozzle may be made of metal, alloy, glass, earthenware or other suitable
material.
The advantages of a nozzle fitted with our invention are that, without introducing
any complicated parts, the liability to choke is obviated.
*
"
In every case the core or spiral director may be used either fitted or fixed in
position, as may be preferred. The core or "director "may be fitted with a ring or
screw, and by that means hung up and preserved from loss when not in use.
The position of the "director may, if required, be fixed in various ways; for
instance, by the shoulder, or by a gradual reduction of the tube, or by a slot in the
tube with a corresponding projection in the "director;" but it is not essential that
there should be any fixing.
On the end of the nozzle (in order, when required, to prevent the spray spreading
too widely) there may also be fitted a secondary piece of pipe. This may be either in
one piece with the nozzle, or screwed on with a thread or sliding on with a spiral
slot, to regulate the length of pipe projecting beyond the nozzle. The projecting
length should be not more than three times the diameter of the tube, and may be
shorter as circumstances require.

Improvements in and Connected with Nozzles for Producing Spray.
We, GEORGE ARTHUR GOYDER, Analytical Chemist, and the Honorable DAVID
MURRAY, Member of the Legislative Council, both of Adelaide, in the Province of
South Australia, 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 :-
The object of our invention is to provide a simple implement for producing a liquid
spray for use in the following ways or purposes amongst others :-1, in watering
gardens; 2, for fountains, revolving lawn waterers; 3, spray condenser for cylinders
of steam engines; 4, spray for chemical works; 5, insecticido spray; 6, shower
bath 7, scent spray; 8, light or heat jets; 9, and for any other purposes requiring
a liquid spray
Our invention consists in an open pipe containing a spiral director' so arranged
and grooved that any liquid introduced into the ingress end of the nozzle must pass
through the spiral grooves and so acquire a rotary motion, which will cause it to issue
from the nozzle as a spray; the egress end of the nozzle being reduced in size, unless
a coarse spray is required. The nozzle may be either straight, curved or angled.
The large end of the nozzle may be either plain, as in Fig. 4, notched, as in Fig. 3,
bulbous, as in Fig. 1, or screwed, as in Fig. 2, for attachment to the supply-pipe.
The spiral director' may be situated anywhere along the inside of the nozzle, and
the grooves may be made either (1st), in the tube-walls with a solid plug running
part of the length of the grooves, but with the grooves extending beyond the plug in
both directions; or (2ndly), the grooves are made in the plug which fits closely in
the nozzle.
The grooves of the spiral director' may be round, half round, square, angular or
of other convenient shape, forming a screw which may be of any pitch and on the
principle of either the common or Archimedian screw. The screw may consists of
any number of grooves.
The egress end of the nozzle may taper with a straight, convex or concave section,
and either in a gradual or sudden manner, or partly re-entering, as shown in
Fig. 4.
The egress end of the nozzle may be made either in one piece with the rest of the
tube, or detachable, or as one or more detachable fittings provided with different-
sized orifices; and these fittings may be screwed on suitable studs which may be
further provided on the nozzle.
Or the egress end may be part of a tube which screws or slides over the main
tube, so that the distance from the spiral director' to the effluent orifice may be
varied.
A filtering chamber may be provided, where necessary, between the nozzle and the
supply-pipe.
The nozzle may be used in conjunction with hydraulic or mechanical pressure, or
with a pump, syringe or reservoir.

In every case, the core or spiral director' may be used either fitted or fixed in
position, as may be preferred. The core or director' may be fitted with a ring or
Screw, and by that means hung up and preserved from loss when not in use.
The position of the director' may, if required, be fixed in various ways; for
instance, by the shoulder, or by a gradual reduction of the tube, or by a slot in the
tube with a corresponding projection in the 'director;' but it is not essential that
there should be any fixing.
On the egress end of the nozzle (in order, when required, to prevent the spray
spreading too widely) there may also be fitted a secondary piece of pipe. This may
be either in one piece with the nozzle, or screwed on with a thread or sliding on with
a spiral slot, to regulate the length of pipe projecting beyond the nozzle. The pro-
jecting length may be of various sizes, from the same diameter as the tube, with a
length about three times the diameter, to twelve times the diameter of the tube, with a
length twelve times the diameter. The wide secondary pipe is used for producing a
soft spray and the narrow one for the reverse.
Figs. 1 to 8 are sectional veiws shewing different modes of fastening the nozzles to
their supply-pipes, as also differently shaped egress apertures. The shaded part in
each figure shows the director.'
Figs. 9 to 13 and Fig. 16 show transverse sections of some of the various shapes in
which the 'director' can be made.
Figs. 14 and 15 are perspective views of a 'director' of the shape shown in Fig. 9.
Figs. 1 to 3 show the supplementary piece of pipe for limiting the spread of the
spray.
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 wo
claim is :-
1. In a spray-producing nozzle, a spiral director, having any number of grooves or
apertures, substantially as described.
2. In a spray-producing nozzle, grooves or apertures made in the sides of the
nozzle and a core or plug fitted or fixed therein, substantially as described.
3. The use, in combination with a director such as referred to in claims 1 and 2,
of a sliding or telescopic nozzle, substantially as herein described, whereby a coarser
or a finer spray is produced upon the nozzle being moved nearer towards or further
from the director.
4. The use, in combination with a director such as referred to in claims 1 and 2, of
a supplementary tube arranged and operating substantially as herein described for
limiting the spread of the spray.
