Abstract
A portable self-piercing riveting system includes a pneumatically driven driver which forces a self-piercing rivet through a workpiece. An anvil carried on a pivotal clamp is moved into operative alignment with the driver on the blind side of the workpiece to receive and set a rivet. The clamp is part of a linkage mechanism which moves the anvil into and out of operative position. When the anvil is in an operative position to receive and set a rivet, the linkage mechanism is in a locked position whereby the impactive force received by the anvil is not transmitted to an actuator for the linkage mechanism.
