Abstract
Abstract A lawn sprinkler for a garden hose is provided and consists of a pair of oppositely extending tubular arms rotatable with respect to a tubular base member, a pair of nozzles each mounted on an arm, a device for adjusting the position of each nozzle with respect to each arm and a pair of water deflectors. Each water deflector is adjustable with respect to each nozzle to receive a jet of water obliquely for purpose of giving motion to each arm and directing the jet of water in any desired direction.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
181 words
A lawn sprinkler for a garden hose which comprises: (a) a tubular base member having an upwardly extending central tubular leg and a hose connector at one end for supplying pressurized water from said garden hose through said base member; (b) a pair of oppositely extending tubular arms having a downwardly extending central tubular leg, said downwardly extending central tubular leg mounted on said upwardly extending central tubular leg of said base member so that said arms are rotatable with respect to said base member; (c) a pair of nozzles with orifices, each said nozzle mounted adjustably on each said arm and including means mounted adjustably in each said orifice whereby the water from the orifice can be variably directed relative to said nozzle; (d) water deflector mounted on said means mounted in each said orifice whereby water issuing from said means mounted in each said orifice will strike said deflectors to move said arms rotatably and deflect the water in a predetermined path, and (e) means for adjusting the position of each said nozzle with respect to each said arm.
Claim 2
Dependent Claim
181 words
A lawn sprinkler for a garden hose which comprises: (a) a tubular base member having an upwardly extending central tubular leg and a hose connector at one end for supplying pressurized water from said garden hose through said base member; (b) a pair of oppositely extending tubular arms having a downwardly extending central tubular leg, said downwardly extending central tubular leg mounted on said upwardly extending central tubular leg of said base member so that said arms are rotatable with respect to said base member; (c) a pair of nozzles with orifices, each said nozzle mounted adjustably on each said arm and including means mounted adjustably in each said orifice whereby the water from the orifice can be variably directed relative to said nozzle; (d) water deflector mounted on said means mounted in each said orifice whereby water issuing from said means mounted in each said orifice will strike said deflectors to move said arms rotatably and deflect the water in a predetermined path, and (e) means for adjusting the position of each said nozzle with respect to each said arm.
Claim 3
Dependent Claim
122 words
A lawn sprinkler for a garden hose as recited in claim 1, wherein the means for adjusting each said nozzle with respect to each said arm comprises: (a) a 90° elbow fitting rotatably attached to end of said arm; (b) a pin mounted transversely within said end of said arm adjacent said elbow fitting; (c) an elongated threaded shaft having one end held captive to said pin with other end extending outwardly from said end of said arm and through side of said elbow fitting; and (d) a nut threadably mounted to free end of said threaded shaft so that said elbow fitting can be turned vertically to axis of said arm in any desired position and locked thereto by said nut.
Claim 4
Dependent Claim
95 words
A lawn sprinkler for a garden hose as recited in claim 1, wherein said means mounted in each said orifice comprises: (a) a cap having a circular socket therein; (b) a ball having a passage therethrough, said ball formed at one end of said ball mates with said socket in said cap so that said tubes can be positioned at any angle with respect to said cap; and (c) a set screw adjustably mounted transversely through said cap adjacent said ball of said tube so that said tube can be locked in any desired position.
Claim 5
Dependent Claim
150 words
A lawn sprinkler for a garden hose as recited in claim 1, wherein the means for adjusting the position of each said nozzle with respect to each said arm comprises: (a) a first 90° elbow fitting attached to end of said arm; (b) a pipe attached to said first elbow fitting; (c) a second 90° elbow fitting rotatably attached to end of said pipe; (d) a pin mounted transversely within said end of said pipe adjacent said second elbow fitting; (e) an elongated threaded shaft having one end held captive to said pin with other end extending outwardly from said end of said pipe and through side of said second elbow fitting; and (f) a nut threadably mounted to free end of said threaded shaft so that said second elbow fitting can be turned hoiizontally to axis of said arm in any desired position and locked thereto by said nut.
