ABSTRACT:
A device for the extraction of the base of a broken light bulb from the socket without further breakage of any remaining glass or deformation of the bulb base member or the socket. A hollow elongated conical cylinder with a series of slots or slits at the apex of the cone is inserted into a light bulb base. A threaded cylindrical rod is screwed into threads inside the conical cylinder, causing the apex of the cone to expand and engage the inside of the light bulb base. When securely engaged, the entire device is turned to cause the light bulb base to be come disengaged from the light socket.
