Abstract : Fluid pressure mechanism for locking a movable rod or similar member in selected positions of adjustment. The mechanism includes a fluid housing having at least one annular rod-gripper element encircling a movable rod. Introduction of fluid pressure into the housing causes the gripper element to expand out of locking engagement with the rod. Removal of the fluid pressure force enables the gripper element to relax into locking engagement with the rod. In a preferred arrangement two rod-gripper elements are employed. The rod passes through the two gripper elements located in opposite side walls of the housing. (Author)
