Abstract
Abstract A sprinkler system characterized by a tubular, substantially square base assembly, and two tubular arm assemblies pivotally coupled to the base assembly. The base assembly is provided with a female coupling receptive to the end of a garden hose such that the base assembly can be pressurized with water. The tubular arm assemblies receive water from the base assembly and are provided with a plurality of sprinkler heads for directing the water as desired by the user. Preferably, the arm assemblies telescope so that their lengths can be varied.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
135 words
A sprinkler comprising: a base assembly including inlet means adapted to receive the end of a garden hose, a pair of outlet means, and primary manifold means for distributing water from said inlet means to said pair of outlet means, said pair of outlet means being pivotally attached to the remainder of said base assembly to permit independent pivotal motion; and a pair of arm assemblies associated, one each, with respective ones of said pair of outlet means, each arm assembly including a first tubular member having a lower end coupled to one of said pair of outlet means, a second tubular member having a lower end portion telescopically engaged with an upper end portion of said first tubular member, and a first sprinkler means coupled to an upper end of said second tubular member.
Claim 2
Dependent Claim
135 words
A sprinkler comprising: a base assembly including inlet means adapted to receive the end of a garden hose, a pair of outlet means, and primary manifold means for distributing water from said inlet means to said pair of outlet means, said pair of outlet means being pivotally attached to the remainder of said base assembly to permit independent pivotal motion; and a pair of arm assemblies associated, one each, with respective ones of said pair of outlet means, each arm assembly including a first tubular member having a lower end coupled to one of said pair of outlet means, a second tubular member having a lower end portion telescopically engaged with an upper end portion of said first tubular member, and a first sprinkler means coupled to an upper end of said second tubular member.
Claim 3
Dependent Claim
66 words
A sprinkler as recited in claim 1 wherein each of said pair of arm assemblies further includes a sleeve valve telescoped over said first tubular member proximate said first tubular member's upper end, said sleeve valve being provided with second sprinkler means which is activated by rotating said sleeve valve to align apertures provided in said sleeve valve with apertures provided in said first tubular member.
Claim 4
Dependent Claim
29 words
A sprinkler as recited in claim 2 wherein each of said pair of arm assemblies further includes a third sprinkler means provided proximate said first tubular member's lower end.
Claim 5
Dependent Claim
34 words
A sprinkler as recited in claim 3 wherein each of said pair of arm assemblies further includes clamping means for restricting the movement of said second tubular member relative to said first tubular member.
Claim 6
Dependent Claim
27 words
A sprinkler as recited in claim 4 wherein said first sprinkler means is coupled to said upper end of said second tubular member by an elbow joint.
Claim 7
Dependent Claim
42 words
A sprinkler as recited in claim 1 wherein said primary manifold means includes a first tubular manifold section coupling said inlet means to a first outlet means, and a second tubular manifold section coupling said inlet means to a second outlet means.
Claim 8
Dependent Claim
35 words
A sprinkler as recited in claim 6 further comprising secondary manifold means coupling said first outlet means directly to said second outlet means, such that a closed fluid path is created around the base assembly.
Claim 9
Dependent Claim
60 words
A sprinkler as recited in claim 7 wherein said primary manifold means and said secondary manifold means are coupled to said pair of outlet means with tubular segments engagng end portions of said pair of outlet means and said primary manifold means and said secondary manifold means, wherein said pair of outlet means may independently pivot on said tubular segments.
Claim 10
Dependent Claim
41 words
A sprinkler as recited in claim 7 further comprising an elastic member formed into a loop engaging the inner walls of said base assembly along said closed fluid path, said elastic member providing a biasing force holding said base assembly together.
