Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
108 words
An intermittent drive sprinkler unit, comprising: a housing having an inlet end and an outlet end, an inlet in said inlet end for connecting to a source of water, an outlet at said outlet end, and passage means connecting said inlet to said outlet; a rotatable head mounted at said outlet end of said housing and including means defining said outlet for distributing a stream of water outward from said housing; a drive assembly including a turbine and a reduction drive train connecting the turbine to the head for rotating said head; means for intermittently interrupting said drive for causing said head to intermittently pause during rotation thereof.
Claim 2
Dependent Claim
108 words
An intermittent drive sprinkler unit, comprising: a housing having an inlet end and an outlet end, an inlet in said inlet end for connecting to a source of water, an outlet at said outlet end, and passage means connecting said inlet to said outlet; a rotatable head mounted at said outlet end of said housing and including means defining said outlet for distributing a stream of water outward from said housing; a drive assembly including a turbine and a reduction drive train connecting the turbine to the head for rotating said head; means for intermittently interrupting said drive for causing said head to intermittently pause during rotation thereof.
