  • Patent number: 4003624
    Abstract: The peripheral edges of the metal eyelet that is embedded in the end of the insulator of an electric lamp base are recessed behind a notched portion of the insulator which prevents the eyelet from being accidentally snagged and "lifted" or otherwise deformed during subsequent bulk processing and shipment of the bases. The notched protective portion of the insulator is formed during the molding of the insulator by making the contactor portion of the eyelet smaller than the corresponding part of the die cavity and centrally positioning the eyelet within the cavity so that the insulating material is forced into the space between the peripheral edges of the contactor portion and the side walls of the molding die.Positioning and retention of the eyelet in the proper location within the cavity is automatically achieved by means of three spaced radially-extending lugs that are located at the bottom of the molding die and form a pocket which receives eyelets that are fed into the die.
