Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
193 words
In a sprinkler head having an impelleR and a nozzle tube rotatable about an upright common axis; improvements in imparting intermittent rotation to the nozzle tube including, a circular disc mounted on and rotatable with the nozzle tube in overlying rotation to the impeller, an angular member projecting from the disc and having a depending outer end portion disposed within the circumference of said impeller and revolvable within an annular path concentric to the rotational axis thereof, a striker pivotally mounted on the impeller for relative swinging movement about an upright axis into the path of the outer end portion of the angular member so as to impart rotational movement intermittently to said nozzle tube through said disc, a pin upstanding from said impeller for pivotally supporting the striker and having its upper end in spaced contiguity to said disc for confining said striker against upward displacement, said striker being in the form of a block having an opening in its inner end portion for mounting on the pin, and upstanding stop means carried by said impeller for limiting pivotal movement of said striker block in the direction of rotation of said impeller.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
24 words
The combination defined in claim 1 wherein the opening of the striker block is offset transversely toward the direction of rotation of the impeller.
