  • Earring clutch
    Patent number: 4928367
    Abstract: An earring clutch defined by a hollow metallic shell filled with an elastomer material. An axial bore extends diametrically through the shell, with each end of the bore terminating at a respective flanged opening. The bore receives the post of an earring in frictional, releasable engagement. To form the clutch, a hollow, apertured shell is submerged in a liquid elastomer material. A vacuum is drawn on the liquid causing the liquid to replace the air in the shell. The shell is removed from the liquid, the liquid elastomer material allowed to harden, and an axial bore then drilled through the hardened elastomer material.
