Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
188 words
An electrical adapter comprising a pair of symmetrical insulating members formed to a predetermined shape to fit the configuration of a hook means; a bus bar means fixedly mounted on the outer surface of each symmetrical insulating member at a predetermined location, the location being positioned to provide electrical contact with an electrical contact means upon suspension of a load means from a lift means integral with the hook means; a terminal means having a pair of leads integral therewith, the terminal means leads being electrically connected to the bus bar means; a plurality of slots formed in the bus bar means, said slots being provided to remove any corrosion from the electrical contact means; an electrical lead means electrically connected to the terminal means at one end of the lead means and electrically connected to an electrical plug connector at the other end of the lead means, the electrical plug connector being provided to electrically connect to a mating electrical plug connector integral with a power supply of the lift means; and means mounted in each symmetrical insulating member to secure the adapter on the hook means.
Claim 2
Dependent Claim
188 words
