Abstract
A collapsible elevator for a package elevating wrapping machine comprises a base member, a package supporting member and a pair of spring-biased rods. The rods resiliently engage the package supporting member to maintain it in a package elevating position relative to the base member, yet permit it to be resettably collapsed relative to the base member upon exertion of a defined force on the package supporting member. The package supporting member comprises a top plate and two downwardly extending spaced supports which have notches in their lower ends for receiving the spring-biased rods. The supports define surfaces which taper inwardly toward the top plate to facilitate resetting the elevator. An electrical switch is coupled to the base member and a switch actuating rod is coupled to the package supporting member and adapted to activate the electrical switch upon collapse of the elevator. The package elevating wrapping machine is shutdown upon a signaled elevator collapse to substantially reduce the possibility of damaging the machine by the jam condition which caused the collapse of the elevator.
