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.

What is claimed is: 1. A panel clamp comprising: a. a base having a longitudinal axis and a first surface with spaced-apart cam abutment locations on opposite sides of the longitudinal axis; b. opposed clamp halves each having: i. a cam surface adapted to abut a corresponding cam abutment location

What is claimed is: 1. A panel clamp comprising: a. a base having a longitudinal axis and a first surface with spaced-apart cam abutment locations on opposite sides of the longitudinal axis; b. opposed clamp halves each having: i. a cam surface adapted to abut a corresponding cam abutment location on the first surface of the base; ii. a clamping surface adapted to abut a side of a panel positioned between opposed clamp halves; iii. an arm extending closer to the longitudinal axis of the base than the cam surface; c. a retainer deposed on an opposite side of arms from the base; and d. a cinching mechanism connected between the base and the retainer adapted to pull the arms toward the base to rotate the opposed clamp halves on the cam surfaces to cause clamping action. 2. The panel clamp of claim 1 wherein the base further comprises a structure for mounting the base to a support. 3. The panel clamp of claim 2 wherein the support comprises a door jam. 4. The panel clamp of claim 2 wherein the support is a floor or ceiling. 5. The panel clamp of claim 1 wherein the panel comprises a glass panel or plate. 6. The panel clamp of claim 5 wherein the glass panel or plate is a shower door. 7. The panel clamp of claim 5 wherein the glass panel or plate is an interior or exterior building door. 8. The panel clamp of claim 1 wherein the longitudinal axis is several inches long. 9. The panel clamp of claim 1 further comprising a gasket deposed adjacent a clamping surface of a clamp halve to abut a side of a panel. 10. A clamp for gripping the edge of a glass plate without needing a notch or hole in the glass plate comprising: a. first and second clamp halves having opposed glass plate clamping surfaces in generally first and second spaced-apart planes defining a glass plate clamping region, opposed extensions with edges extending inwardly towards each other from the two planes; and opposed cam edges extending in generally the same direction from the same side of each clamp halve and on outside sides of the two planes; b. a base plate having a surface into which the cam edges come into abutment; c. a member positioned from the base plate relative to the edges of the opposed extensions; d. a cinching mechanism between the base plate and the member that, when operated, moves the member towards the base plate which, in turn, moves the clamp halves on the cam edges to provide clamping action. 11. The clamp of claim 10 in combination with a glass plate. 12. The combination of claim 11 wherein the glass plate is a transom. 13. The combination of claim 11 further comprising a second clamp adapted for use on the glass plate. 14. The combination of claim 11 wherein the glass plate comprises a door. 15. The combination of claim 14 wherein the door is a building door. 16. The combination of claim 14 wherein the door is a shower door. 17. The clamp of claim 10 further comprising a hinge between the clamp halves and the base plate.
