Abstract: A hand held plastic rod gripping tool 25 is especially adapted for forcefully pushing thin cylindrical plastic rods into a resident pivot joint site between two modular links of a conveyor belt. Plastic pivot rods are difficult to insert manually because they are thin, and easily flexed, making them hard to grasp frictionally in the fingers at a stiff short section for forceful axial insertion. Also some conveyor modules require the rods or the modules to be distorted for snapping in over a barrier ridge thus requiring more force for initial entry. The tool 25 has a cylindrical knurled 26 hand grip body, of a diameter that permits a firm grasp, through which extends an axial passageway, typically a slot 27, for entry of the rod. A manually movable gripper assembly 45 is generally laterally movable to frictionally contact a rod 10 held within the tool body. Within an interior channel 49 at an acute converging angle 50 toward a rod 10 the gripper 45 is spring biassed 46 to move toward the rod surface.

Abstract: A pneumatic system for absorbing and storing the recoil force of an electromagnetic riveter, and for positioning the elements of the machine where desired for optimal operation, includes a set of recoil cylinders connected between a base plate and a support plate on which the riveter is mounted. When the electromagnetic actuator of the riveter is energized and the recoil mass of the riveter is repelled away from the driver, the recoil cylinders absorb and damp the energy of recoil, and then the stored energy in the recoil cylinders acts to restore the recoil mass to its starting position. A set of damping cylinders prevents the recoil mass from slamming against the mechanism at the end of its return stroke. A set of pop-back cylinders holds the electromagnetic riveter at an elevated position wherein the end of the driver is clear of the top end of a shuttle having several stations, one of which holds a rivet die.
