Complete Specification Left, 26th Feb., 1895-Accepted, 30th Mar., 1895
I, George FREDERICK STRAWSON, of Horley, Surrey, Inventor, do hereby
declare the nature of this invention to be as follows
This invention is for a combined nozzle for spraying liquids and a swivel joint
upon which it works.
The swivel consists of two hollow hemispheres of metal or other material placed
together at their edges and held together by a screw passing through at right angles
to the edges of the hemispheres. These edges are suitably grooved and washered to
hold them watertight. At the same time they can be revolved upon each other
upon the axis of the screw. Out of the hollow vessel thus constructed are two or
more openings, one to allow the liquid to enter the cavity, the other to allow it to pass
out at a tangent into a spraying nozzle which is fixed on any suitable part of the
vessel.

I, GEORGE FREDERICK STRAWSON, of Horley, Surrey, Inventor, 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 is for a combined nozzle for spraying liquids and a swivel joint
upon which it works.
The swivel consists of two hollow hemispheres of metal or other material placed
together at their edges and held together by a screw passing through at right
angles to the edges of the hemispheres. These edges are suitably grooved and
washered to hold them watertight. At the same time they can be revolved upon
each other upon the axis of the screw. Out of the hollow vessel thus constructed
are two or more openings, one to allow the liquid to enter the cavity, the other to
allow it to pass out at a tangent into a spraying nozzle which is fixed on any suitable
part of the vessel.
to explain my meaning reference is made to the accompanying
The better
drawing in which
Fig. 1 is an elevation.
Fig. 2 is a section.
Fig. 3 is a section of a button or plug for changing the character of the stream.
In the drawing it will be seen that the swivel arrangement is effected by forming
the ball in two parts A and B, the part A. having the tube attached which at the
other end is preferably so formed as to admit of the ready attachment of a rubber
tube from the reservoir. The portion B. has a screwed projection to take a cap C.

page_text: the opening in which may be of any desired form, or other similarly shaped caps
having openings of modified form may be used according to the character of the
required spray or stream.
The portion B. is held by the screw D. which is free to rotate in the hole in the
part A. and as the division between the two parts is made at an angle of or about 45°.
with the axis of the supplying tube, and the delivery nozzle on part B. is also
at or about 45° with the plane of division, it is readily seen that a spray may be
thrown at right angles to the supply tube whilst by giving the part B. a half
turn on the axis of rotation (which of course coincides with the centre of the
screw D.) the nozzle C. will be brought in alignment with the supply tube and
the jet or spray will take a direction accordingly.
By a quarter turn or any other proportionate movement a proportionate
angle between the direction of the supply tube and the direction of the spray
is produced.
Leather washers E. are used to produce a water-tight fit.
An internal button F. Fig. 3. may be dropped in the cavity G. which has the
effect of modifying the character of the jet depending on which end lies nearest the
nozzle.
One end of the button it will be noticed is of a convex form, whilst the other. is
concave.
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. The construction of a swivel joint and nozzle composed of two hemispherical
parts, the dividing plane between which is formed at such an angle to the axis of
the delivery and supply openings that the spray delivery may be directed at any
angle with the supply pipe, from a right angle, to finally, in alignment therewith,
by the rotation of one hemisphere upon the other substantially as described and
illustrated.
2. The combination with the above of a loose button formed with one end convex
and the other concave and having a central hole, so that the character of the spray
or jet may be modified thereby substantially as described and illustrated.
