Abstract
1438255 Load clamping CASCADE CORP 20 May 1974 [7 June 1973] 22437/74 Heading B8H [Also in Division F1] In a load clamping mechanism comprising opposed gripping arms at least one of which is moved by a fluid-powered ram, a coiled compression spring is interposed between relatively extensible contractible parts of a rod assembly of the cam, to provide a limited amount of play in the arm structure. Fig. 1 shows a plan view of the arms 12 and 14 gripping a cylindrical roll, while Fig. 2 shows an enlarged view of one of the rams, 32 and the compression spring 86 mounted on the rod assembly 50 such that when the rod has been extended or contracted by the desired amount, it is still capable of limited extension or contraction due to the compression of the spring without using the hydraulic system.
