US Patent 7493673 Notchless glass plate clamp

An apparatus and method for clamping a panel, such as a glass panel, with no notch or drilled hole. The apparatus includes a base and two opposite opposing clamp halves. The lower edges of the clamp halves have downwardly extending cam surfaces. Inwardly extending arms are formed near the bottom of the clamp halves. A retainer is positionable above the arms and base. A machine screw is turned to pull the retainer to pull the arms towards the base and force the cam surfaces against the base. This causes convergence of the clamp halves by the geometry of the cams.
