Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 199 words
A hollow, sealed golf club comprising; an elongated, cylindrical, transparent hollow tube, said tube having filling means, a hand grip, said hand grip having means to attach said hand grip to a proximate end of said tube, a hollow golf club head, said hollow golf club head having means to attach said club head to a distal end of said tube opposite said proximate end, said tube and said golf club head being internally connected and partially filled with a flowable material, said tube having at least two externally controlled valve means, said valve means separating said tube and said head into at least three compartments, said valve means having a first and second position, said first position allowing said flowable material to pass through said valves, said second position not allowing said flowable material to pass through said valves, said transparent tube having indicia to indicate the proportions of said flowable material in each of said compartments; said filling means, said hand grip, said hollow golf club head, said externally controlled valve means, said compartments, said indicia and said flowable material cooperating together to allow said flowable material to be captured in visible variable proportions in said compartments.
Claim 2
Dependent Claim 199 words
A hollow, sealed golf club comprising; an elongated, cylindrical, transparent hollow tube, said tube having filling means, a hand grip, said hand grip having means to attach said hand grip to a proximate end of said tube, a hollow golf club head, said hollow golf club head having means to attach said club head to a distal end of said tube opposite said proximate end, said tube and said golf club head being internally connected and partially filled with a flowable material, said tube having at least two externally controlled valve means, said valve means separating said tube and said head into at least three compartments, said valve means having a first and second position, said first position allowing said flowable material to pass through said valves, said second position not allowing said flowable material to pass through said valves, said transparent tube having indicia to indicate the proportions of said flowable material in each of said compartments; said filling means, said hand grip, said hollow golf club head, said externally controlled valve means, said compartments, said indicia and said flowable material cooperating together to allow said flowable material to be captured in visible variable proportions in said compartments.
