Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
A runnerhead for a throwing wheel, said runnerhead comprising a plate member having a face and at least one vane receiving channel formed in said face for receiving a throwing vane, and locking means for locking said throwing vane in said vane receiving channel, said locking means including a locking pin hole for receiving a locking pin, said locking pin hole having an axis and being formed in said plate member and extending along said axis angularly inwardly from said face; the improvement comprising a locking pin release channel means formed in said plate member contiguous with said locking pine hole and spanning said locking pin hole for allowing a locking pin to be removed from said locking pin hole in a direction other than along said axis.
Claim 2
Dependent Claim
