Electrical power cord and appliance using same

An electrical appliance or machine including an electrical power cord comprising a plug having prongs for insertion in an electrical outlet, an electrical insulating tubular member disposed about the plug, said plug and said tubular member being relatively movable, spring means disposed between the tubular member and the plug and compressed while the prongs are inserted in the outlet so as to bias the plug in a direction away from the outlet, means disposed on the tubular member for releasably interlocking the tubular member and the plug when the prongs are inserted in the outlet, wire coil means disposed on the tubular member, magnetically susceptible trip means disposed between the tubular member and the plug for movement in response to energization of the wire coil means, manually operable switch means on the appliance or machine and operably associated with said cord for passing an electrical current through the coil means while the prongs are inserted in the outlet to move the trip means in a manner to disengage the interlocking means and allow the spring means to eject the plug from the outlet.

An electrical power cord comprising a plug having prongs for insertion in an electrical outlet, a magnetically susceptible member fixedly mounted on the plug, an electrical insulating tubular member disposed about the plug and having wire coil means disposed thereon, said tubular member and plug being relatively movable, manually operable switch means operably associated with said cord for passing an electrical current through the coil means while the prongs are inserted in the outlet to effect movement of the magnetically susceptible member relative to said tubular member in a manner to eject the plug from the outlet.
