A communication from MAURICE PARKER BARKER, Gentleman, of Watertown,
Codington County, South Dakota, United States of America.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Member of the Institution of Mechanical 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 improvements in nozzles particularly intended for
spraying water from hose although adapted for use wherever it is desired to
spray or comminute jets of water, air, gas, steam or other medium, and has for its
object to provide a device of this character which will effectually spray or comminute
the jet or column of water or other medium issuing from the nozzle without
interrupting or retarding the flow in the least.
In carrying out the invention the principle of the pneumatic paradox or
aspirating action of currents of air or liquid is employed, which principle it is well
known, will retain a valve on its seat under pressure of gas or liquid, only allowing
a film to escape around the periphery of the valve.
In carrying my invention into practice I preferably provide a bell mouth nozzle
having a central jet opening of relatively small diameter and adapt to this opening
a sphere or ball with means for preventing its loss or entire separation from the
nozzle without, however, necessarily retaining it at all times in the path of the
escaping jet, thus rendering it possible to make a spray or solid jet with the same
nozzle.
Referring to the accompanying drawings:
Figure is a perspective view of a nozzle constructed in accordance with my
present invention.
Figure 2 is a sectional view longitudinally of the same.
Figure 3 is a side elevation with the sphere or ball out of the bell mouth to
permit of the projection of a solid jet.
Like letters of reference indicate the same parts in all the figures.
The length, diameter or capacity of the nozzle, of course, has little to do with
the invention, hence for convenience, I have illustrated it as embodied in an ordinary
garden hose nozzle of small size, such as is adapted to be held in the hand, or
be mounted in a holder in vertical position to give the effect of a fountain.
The nozzle proper lettered A is screw threaded at the base a for attachment
to the hose or water supply pipe and at the forward or outer end is formed into a
bell mouth B of convenient size for the reception of a sphere or ball C.
This sphere or ball should fit well down within the mouth of the bell to secure
the best results and is preferably formed of rubber.
Bridging the bell mouth is a frame for preventing the loss of the sphere or ball
and in the preferred construction this frame is formed by two wires D bridging the
bell mouth and bent out at the side to form a seat in which the ball may rest out
of line with the jet opening as illustrated in Figure 3 to permit of the projection of a
solid jet from the nozzle.
In operation when a spray is desired the ball is dropped into the bell mouth and
the water turned on, the result being that the ball is held within the bell mouth_as
before explained and the water escapes around the same in a fine spray. The
effectiveness of the device is increased by forming a series of inclined notches G
n the surface of the sphere or ball which cause it to rotate very much more rapidly
han would otherwise be the case, thereby equalizing the spray and projecting it
na most perfect and regular cone.

page_text: The device is simple having no parts liable to get out of order or be broken
with ordinary use, facts which at once commend it to the public, and further, it
allows the full volume of water to escape in the form of spray, a result which
cannot be accomplished with the ordinary spraying nozzle depending as they do
upon obstructions tending to hold the water within the supply pipe or hose.
The field of utility of the present invention it will be seen is not limited to hose,
but extends to any of that large class of devices and apparatus in which it is
desired to comminute or spray a jet of air, gas, water or other medium for any
purpose whatever.
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 distributing nozzle having a bell mouth with a loose sphere or ball fitting
within said bell mouth substantially as described.
2. A distributing nozzle having a bell mouth with a loose sphere or ball fitting
said bell mouth and the frame for preventing the loss or entire separation of the
ball from the nozzle; substantially as described.
3. A distributing nozzle having a bell mouth with a loose sphere or ball fitting
in said bell mouth and the frame bridging said bell mouth bent out at the side to
hold the ball out of the path of the jet issuing from the nozzle; substantially as
described.
4. A distributing nozzle having a bell mouth with a loose sphere or ball fitting
in said mouth and provided with surface irregularities to equalize the spray :
substantially as described.
5. A distributing nozzle having a bell mouth with a loose sphere or ball fitting
in said mouth and provided with inclined recesses in its surface; substantially as
shown and set forth.
Dated this 5th day of August 1892.
