Total Claims: 13
Claim 1
Independent Claim
330 words
A sprinkler of the type having a water inlet housing supporting an outlet nozzle assembly thereon for pivotal movement about a substantially vertical support axis in such manner that water supplied to said housing is discharged through said outlet nozzle assembly as a water jet having a discharge axis inclined to said support axis and a flow deflecting assembly adapted for intermittent engagement with said water jet to cause incremental rotation of said outlet nozzle assembly about said support axis, characterized in that said flow deflecting assembly includes a support structure and flow deflecting means supported thereby for movement between an engaged position in which said deflecting means engages said water jet to deflect said jet to one side of said nozzle to maintain said flow deflecting assembly in said engaged position and cause said nozzle to pivot about its support axis in the forward direction, and a disengaged position in which said deflecting means is disposed remote from said water jet, said flow deflecting means including a deflecting blade assembly having a forward deflecting face engageable with said water jet so as to cause said forward pivoting of said outlet nozzle assembly and a reverse-deflecting face engageable with said water jet to cause deflection thereof for deflecting said water jet to the other side of said nozzle to cause said flow deflecting assembly to move to said disengaged position and driving vane means associated with said deflecting blade assembly and adapted to engage said water jet simultaneously with said deflecting blade assembly to move the latter through said water jet, the parts being so made and arranged that said forward-deflecting face is arranged at the leading end of said deflecting assembly and said reverse-deflecting face is disposed at the trailing end of said deflecting blade assembly, whereby engagement between said reverse-deflecting face and said water jet subsequent to engagement between said water jet and said forward-deflecting face causes said disengagement between said flow deflecting assembly and said water jet.
Claim 2
Dependent Claim
330 words
A sprinkler of the type having a water inlet housing supporting an outlet nozzle assembly thereon for pivotal movement about a substantially vertical support axis in such manner that water supplied to said housing is discharged through said outlet nozzle assembly as a water jet having a discharge axis inclined to said support axis and a flow deflecting assembly adapted for intermittent engagement with said water jet to cause incremental rotation of said outlet nozzle assembly about said support axis, characterized in that said flow deflecting assembly includes a support structure and flow deflecting means supported thereby for movement between an engaged position in which said deflecting means engages said water jet to deflect said jet to one side of said nozzle to maintain said flow deflecting assembly in said engaged position and cause said nozzle to pivot about its support axis in the forward direction, and a disengaged position in which said deflecting means is disposed remote from said water jet, said flow deflecting means including a deflecting blade assembly having a forward deflecting face engageable with said water jet so as to cause said forward pivoting of said outlet nozzle assembly and a reverse-deflecting face engageable with said water jet to cause deflection thereof for deflecting said water jet to the other side of said nozzle to cause said flow deflecting assembly to move to said disengaged position and driving vane means associated with said deflecting blade assembly and adapted to engage said water jet simultaneously with said deflecting blade assembly to move the latter through said water jet, the parts being so made and arranged that said forward-deflecting face is arranged at the leading end of said deflecting assembly and said reverse-deflecting face is disposed at the trailing end of said deflecting blade assembly, whereby engagement between said reverse-deflecting face and said water jet subsequent to engagement between said water jet and said forward-deflecting face causes said disengagement between said flow deflecting assembly and said water jet.
Claim 3
Dependent Claim
75 words
A sprinkler according to claim 1, characterized in that said driving vane means includes a plurality of spaced-apart vanes arranged to sequentially engage said water jet upon movement of said deflecting blade assembly through said water jet and there being provided vane adjustment means operable to vary the number of vanes which will in operation engage said water jet whereby the time of engagement between said deflecting means and said water jet may be varied.
Claim 4
Dependent Claim
111 words
A sprinkler according to claim 1, characterized in that said support structure includes a pivot arm supported for pivotal movement on said nozzle assembly about an upwardly extending axis, said pivot arm when supporting said deflecting means in said engaged position being restrained against forward rotation relative to said outlet nozzle assembly whereby when said deflecting means is in said engaged position said pivot arm and said outlet nozzle rotate in unison in a forward direction about said support axis, and said pivot arm being free to pivot relative to said nozzle assembly in the reverse direction to said disengaged position upon engagement between said water jet and said reverse-deflecting face.
Claim 5
Dependent Claim
92 words
A sprinkler according to claim 2, wherein said deflecting blade assembly includes a forwardly-deflecting part formed as a sector of a cylinder and supported pivotally about a sector axis which extends substantially parallel to the cylinder axis and substantially in the direction of said discharge axis and wherein said driving vanes extend between said axis and said deflecting blade and are arranged to deflect a portion of said water jet in a direction tangential to said sector axis so as to cause said deflecting blade assembly to pivot about said sector axis.
Claim 6
Dependent Claim
71 words
A sprinkler according to claim 3, wherein there is provided selectively engageable lock means operable to prevent said pivot arm pivoting in said reverse direction relative to said nozzle assembly, whereby in operation when said reverse-deflecting face is engaged with said water jet said reverse deflection of said water jet will cause said nozzle assembly and said pivot arm to pivot in unison about said support axis in the reverse direction.
Claim 7
Dependent Claim
90 words
A sprinkler according to claim 5 wherein said lock means is engaged by co-action, resultant from forward rotation of said nozzle assembly, with a selectively positionable first stop member mounted on said inlet housing and wherein said lock means is adapted to be disengaged upon co-action, resultant from reverse rotation of said nozzle assembly, between said nozzle assembly and a second selectively positionable stop member mounted on said inlet housing such that the relative positions of said first and second stop members determines the sector of operation of said sprinkler.
Claim 8
Dependent Claim
66 words
A sprinkler according to claim 5, wherein said lock means is adjustable so as to provide limited movement of said pivot arm away from said nozzle assembly in said reverse direction, whereby in operation said reverse-deflecting face may move part-way out of engagement with said water jet so as to reduce the reaction between said face and said jet and the speed of second reverse rotation.
Claim 9
Dependent Claim
81 words
A sprinkler according to claim 7, wherein said lock means includes an abutment member mounted on said outlet nozzle and movable between a locked position and an unlocked position, said abutment member when in said locked position being spaced from the pivot mounting of said pivot arm and adapted when the latter is disposed in said engaged position to interfere with said pivot arm in such manner as to prevent pivotal movement of the latter relative to said outlet nozzle assembly.
Claim 10
Dependent Claim
61 words
A sprinkler according to claim 8 wherein said abutment member is associated with a linkage assembly supported on said outlet nozzle assembly, said linkage assembly including contact means adapted upon rotation of said outlet nozzle assembly to co-act with a respective one of said stop members to move the abutment member in the respective direction to its locked or unlocked position.
Claim 11
Dependent Claim
72 words
A sprinkler according to claim 3, wherein said pivot arm is pivoted at its end remote from said deflecting means about an upwardly extending pivot axis disposed adjacent to said support axis and inclined thereto in such manner that during pivotal movement of said pivot arm from said engaged position to said disengaged position, said free end moves sideways and upwards so as to be biased by gravity towards said engaged position.
Claim 12
Dependent Claim
33 words
A sprinkler according to claim 10, wherein an adjustable biasing spring means is connected between said pivot arm and said nozzle assembly and adjustable to urge said pivot arm towards said engaged position.
Claim 13
Dependent Claim
51 words
A sprinkler according to claim 1, wherein said inlet housing supports said outlet nozzle assembly by means of a ball and socket joint and there being provided adjustment means interposed between said ball and said socket whereby the angle between said support axis and said discharge axis may be selectively varied.
