Abstract

A self-tightening clamp adapted on closure to suspend a sheet of glass where the clamp includes a stirrup and levers pivotally mounted on the ends of the stirrup with a sheet engaging stud at the end of each lever positioned above the pivot point of the lever. An arm is pivotally mounted at one end to the end of each lever and at its other end is pivotally connected to a suspension link. Guides are associated with the stirrup and the suspension link to assure that the stirrup will move vertically with respect to the suspension link during opening and closing of the clamp. Stops are associated with the stirrup to limit pivotal movement of the levers towards each other and to limit movement of the studs towards each other whereby when the clamp is fully closed, the studs are spaced apart slightly less than the width of the sheet with which they are to engage so as to embed slightly into the sheet.
