Abstract:
1. A clamping plate assembly for movement laterally into and out of engagement with a load including in combination: a main plate member having front, rear, upper and lower edges; an auxiliary plate overlying the main plate member and extending from the lower edge of the main plate member a predetermined distance toward the upper edge thereof and extending substantially from the rear edge of the main plate member to the front edge thereof, where the predetermined distance is a fraction of the distance between the lower and upper edges of the main plate member, with the auxiliary plate removably attached to the main plate member; and yieldable friction material over substantially the major portions of the auxiliary plate and the portion of the main plate member not covered by the auxiliary plate; wherein the thickness of the yieldable friction material on the portion of the main plate member is greater than the thickness of the auxiliary plate; and the thickness of the yieldable friction material on the auxiliary plate is selected to cause the exposed surface of the yieldable friction material on the auxiliary plate to be in the same plane as the exposed surface of the yieldable friction material on the main plate assembly.
