Improvements in Lawn Sprinklers.
I, CLEMENT COWARD, of 188, Grove Street, Liverpool, in the County of
Lancaster, Metal Merchant, do hereby declare the nature of this invention to be
as follows:-
This invention has for its object a water sprinkler or distributor for lawns and
other purposes. The invention comprises a socket or nozzle which may be screwed
to the end of a hose or on to a standard of suitable construction, a bracket supported
on said socket or nozzle, and a rotatable distributor or disc mounted concentrically
with the said nozzle on the bracket. The rotatable distributor is formed in a
peculiar manner being made with its centre projecting concentrically downwards
towards the nozzle, and the remainder of the under-face where the water impinges
formed of a series of blades or flutings of unequal length, some of these flutings
being quite short and others extending to near the centre of the disc. The disc by
preference revolves on a pointed pivot on the end of the bracket, a set screw engaging
a groove in the bracket, keeping the disc in place. The water issuing through
the nozzle impinges directly on the disc which owing to the peculiar form of the
flutings or blades is made to rapidly revolve, and the water is deflected being dis-
tributed in a spray over a considerable area. The fineness of the spray and the
angle of deflection may be varied by adjusting the distance of the disc from the
nozzle which is effected by mounting the bracket on the nozzle in an adjustable
manner so that the bracket can be raised or lowered as required. The nozzle may
have a projecting arm to support the bracket if desired, and avoid excessive vibration,
and also by having lateral projections with grooves at intervals for engaging the
bracket the said bracket may be adjusted so that its distributor or disc may be fixed
concentrically with the nozzle or eccentrically therewith.

I, CLEMENT COWARD, of 188, Grove Street, Liverpool, in the County of
Lancaster, Metal Merchant, 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 has for its object a lawn sprinkler or distributor for lawns and
other purposes..
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which,
Figure 1 is a general view of the sprinkler;

page_text: Figure 2, a sectional elevation; and
Figure 3, an inverted plan of the face of the distributor or disc against which
the water from the nozzle impinges.
The invention comprises a socket or nozzle A which may be screwed to the end
of a hose or on to a standard of suitable construction, a bracket B supported on said
socket or nozzle, and a rotatable distributor or disc mounted concentrically with the
said nozzle on an arm B' of the bracket. The rotatable distributor C is formed in a
peculiar manner, being made with its centre c projecting concentrically downwards
towards the nozzle A, and the remainder of the under face where the water impinges,
formed of a series of blades or flutings c of unequal length and unequal depth,
some of these flutings being quite short and others extending to near the centre of
the disc forming spiral curves. The disc C by preference revolves on a pointed
pivot b at the end of the arm B', a set screw D engaging a groove in the bracket and
keeping the disc in place. The water issuing through the nozzle A impinges directly
on the disc C, which owing to the peculiar form of the flutings or blades is made to
rapidly revolve and the water is deflected, being distributed in a spray over a consider-
able area.
The fineness of the spray and the angle of deflection may be varied by
adjusting the distance of the disc C from the nozzle A, which is effected by screwing
the nozzle A into the bracket B and locking the nozzle therein by means of a nut E.
By loosening the nut and screwing the bracket up or down, the bracket can be
raised or lowered as required. The bracket may have a projecting support B² to
support the bracket arm B' and avoid excess of vibration, the arm locking itself on
the support by spring pressure. By having lateral projections with grooves Fat
intervals for engaging the bracket arm, the said arm may be adjusted so that its
distributor or disc may be fixed concentrically with the nozzle or eccentrically
therewith.
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 lawn sprinkler, comprising a socket or nozzle for water, and a rotary con-
centric water distributor or disc fluted on its under face, and located above and facing
the nozzle outlet in proximity thereto, whereby the water issuing through the nozzle
will impinge directly on the disc and rotate it, the water being deflected in a spray
over a considerable area, substantially as described.
2. In a lawn sprinkler, a rotary spray distributor or disc, a bracket for supporting
the disc, and a nozzle on which the bracket is adjustably mounted in such a manner
that the distance of the rotary disc from the nozzle can be adjusted substantially as
and for the purpose described.
3. In a lawn sprinkler, and in combination, a bracket supported on the nozzle,
having a lateral extension or support projecting therefrom, and a springy bracket arm
carrying the distributor against which the water impinges and is deflected in the
form of spray, the said bracket arm being adapted to lock firmly against the
extension by exerting spring pressure thereon substantially as described.
4. In a lawn sprinkler, forming the under face of the distributor or disc against
which the water from the nozzle impinges with blades or flutings, substantially as
and for the purpose described.
