PROVISIONAL SPECIFICATION.
Improvements in Adjustable Spreading Nozzles for Horticultural
and other Purposes.
I, EDWIN HAINES of Paddock Wood in the County of Kent, Mechanic do
hereby declare the nature of this invention to be as follows:-
According to my invention I construct nozzles for horticultural and other
purposes with the usual hole right through but in order to break up the stream
of liquid I insert a somewhat conically shaped plug in the nozzle provided with
two or more helical grooves on the outside. The inside of the delivery end of
the nozzle is fashioned to correspond somewhat with the end of the plug and
the latter is so arranged as to be capable of being moved further or nearer the
delivery end of the nozzle by means of a screw or otherwise. The nozzle may
be combined with a valve or cock or not. If a valve be used I prefer to have
an eccentric boss cast in one with the end of the nozzle and have a screwed cap
thereon with a hole away from the centre so that when the cap is screwed up
such hole does not come in line with the delivery hole of the nozzle but in such
manner that say half a turn back will bring the two holes in a line and allow.
the stream of liquid to pass through the nozzle.

COMPLETE SPECIFICATION.
Improvements in Adjustable Spreading Nozzles for Horticultural
and other Purposes.
I, EDWIN HAINES of Paddock Wood in the County of Kent Mechanic do
hereby declare the nature of this invention and in what manner the same is to be
perforined to be particularly described and ascertained in and by the following
statement :-
According to my invention I construct nozzles for horticultural and other
purposes with the usual hole right through but in order to break up the stream of
liquid I insert a cone or somewhat conically shaped plug in the chamber of the
nozzle provided with two or more grooves on the outside. The inside of the
delivery end of the nozzle is fashioned to correspond more or less with the end of
the plug and the latter is so arranged as to be capable of being moved further from
or nearer to the delivery end of the nozzle by means of a screw or otherwise.
On the accompanying sheet of drawings I have illustrated some nozzles con-
structed according to my invention of which
Figure 1 is a sectional elevation of a spreading nozzle with a simple form of shut
off valve.
Figure 2 is a plan view showing the shape of the top of the conically shaped
plug which has three helical grooves of an angular section and
Figure 3 is a plan section of the plug on line W X Figure 1.
Figure 4 is a plan view showing the shape of the top of a modification of plug
having four angular helical grooves and
Figure 5 is an elevation of same.
Figure 6 is a plan view of top of another modification of tapered plug with two
partly circular grooves and
Figure 7 is an elevation thereof.

page_text: Figures and are respectively plan of top and elevation of another plug with
two angular grooves.
Figure 10 is a plan of the top of a plug having four angular grooves.
Figure 11 is a sectional elevation of a nozzle having a plug the top of which is
shown in plan in Figure 10 and
Figure 12 is a plan section of the plug on line YZ Figure 11.
Figures 13 and 14 are respectively a plan and sectional elevation of a plug
having a central hole for conveying the water or liquid to a transverse hole whence
it issues to the partly circular grooves.
Figures 15 and 16 are respectively plan of top and elevation of a slightly modified
form of nozzle to that shown in Figures 6 and 7.
Figures 17 and 18 are respectively plan and sectional elevation of modification of
plug in some respects similar to those shown in Figures 4 and 5 and 13 and 14.
Figures 19 and 20 are respectively sectional elevation and plan of the shell of a
nozzle with a movable slide in the cap in lieu of using an eccentrically mounted
screw cap as shown in Figure 1.
Referring to Figures 1, 2, and 3 the chamber of the nozzle A is provided with
the usual through hole B and in order to break up the stream of liquid I insert a
somewhat conically shaped plug C provided in this case as aforesaid with three
grooves g. The inside of the delivery end of the nozzle A is fashioned to
correspond somewhat with the end of the plug C and the latter is provided with a
screw thread so as to be capable of being moved further.or nearer the delivery end
of the nozzle in same.
The spindle c is for the purposes of turning the plug and adjusting the spray.
The nozzle A may as shown be screwed on the outside of its upper eccentric boss
and have a correspondingly screwed cap D thereon with a hole E away from the
centre so that when the cap D is screwed down such hole does not come in line with
the hole B of the nozzle but in such manner that say half a turn back will bring
the two holes in a line and allow the stream of liquid to pass through the nozzle in
a continuous spray.
The cap D is provided with a washer F to prevent leakage when the valve is
closed.
In Figures 4 and 5 the plug is provided with a hole g going through the spindle c
and communicating by a transverse hole g² shown in dotted lines with the outside of
the plug and interior of the nozzle.
In Figures 6 and 7 and 8 and 9.the screw on the plug is partly filed away on
each side and communication to the grooves is thus effected.
Referring to Figures 10, 11 and 12 the nozzle A is shown.without a valve..
In Figures. 13 and 14.the plug C is shown provided with a central hole g' going
through the spindle c and communicating by the transverse hole g³ to the grooves g
and interior of the nozzle. The grooves are made through the screwed parti and
streams of water also flow by them as well as the stream by the central hole.
Figures 15 and 16 as aforesaid illustrate a slightly modified form of plug to that
shown in Figures. 6 and .7.
Figures 17 and 18 show a plug which is provided with the central hole g',
transverse hole g² and grooves g..
Referring to Figures 19 and 20 the nozzle A. is provided with a cap D similar to
that described with reference to Figure 1 but instead of mounting the cap
eccentrically to the centre of the nozzle, it is mounted concentrically and has a
slide C mounted in a dovetailed slot in the top as shown or otherwise and when
inserted in such dove-tailed slot or groove the tongue e formed by two saw cuts in
the end of the slide C¹ is bent down and thus prevents said sliding piece from
slipping out and being lost.
In Figure 20 the valve is shown open but in order to close it the cap D is
slightly unscrewed, the slide is drawn up until stopped by the stop or tongue e
coming into contact with the side of the cap, the latter is then screwed down and
seating itself on the washer F prevents the egress of the liquid.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A spreading nozzle for horticultural and other purposes having an adjustable
cone or more or less tapered plug with grooves for causing the liquid passing
through to break up into spray when discharged substantially as described and
shown.
2. The constructions of nozzles with valves as shown.
3. The constructions of cones or tapered plugs as shown.
