Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 126 words
A signalling device used on a fishing rod comprising: a housing; said housing having means for effecting carriage thereof by said fishing rod, and having chamber means for replaceably supporting bi-terminal electrical batteries and lamp; magnetic switch means responsive to magnetic signal means; said magnetic switch means effecting an electrically conducting engagement between said batteries and said lamp to produce a sensible signal; wherein said magnetic signal means include means selectively adjustable for infinitelY controlling the movement thereof, and comprises a rotatable pulley system having a magnetic pulley and a simple pulley engaging fishing line of said fishing rod; said selectively adjustable means comprises a slidable member in captive engagement with said carriage means and said pulley system, said engagement compressibly maintained by spring means there-between.
