  • Patent number: 4212311
    Abstract: A manually operable eyelash curler including a pair of curved arms housed within a stationary frame, which when mechanically depressed along the outermost curved portion, drives a movable, non-electrically heated eyelash compressing element into intimate contact with a stationary electrically heated eyelash compressing element, a centrally-disposed battery pack to provide the electrical energy to heat the electrically heated eyelash compressing element, a first electrical switch which arms the electrical circuit, and a second electrical switch operably associated with one of the curved arms to energize the electrically heated eyelash compressing element when the curved arm is manually depressed.
