ABSTRACT:
An improved mechanical cork puller wherein the pivot holes of the lever arms receive and pivot about one or more ribs formed on the inner surfaces of the opposed pairs of support ears, resulting in no visible sign of a pivot support on the outer surfaces of the support ears. The support ears have an inwardly diverging taper providing free meshing movement between the toothed sectors of the lever arms and the cork puller shaft. To manufacture, elongated rib members are initially die-cast on the inner surfaces of the support ears and thereafter cut away to the desired length to form the pivot support for the lever arms. As cast, the inner surfaces of the support ears diverge outwardly and thereafter the outer ends of the support ears are bent toward each other so that the inner surfaces thereof diverge inwardly. The lever arms are thereafter assembled by merely forcing fitting them into place between the support ears.
