Abstract
A riveting tool of the kind having an elongate, headed, mandrel on which a plurality of tubular rivets are supported as a column, and which can be gripped and reciprocated relative to an abutment by reciprocable gripping jaws so as to draw the head of the mandrel through each rivet supported in turn by the abutment, and having a mechanism for feeding the column of rivets towards the head of the mandrel, has both the rivet feeding mechanism and the gripping of the mandrel by the jaws operated pneumatically, each respectively being under the control of a manually operable valve. In order to avoid the possibility of the feeding mechanism being actuated at a time when the mandrel is not gripped by the jaws, the valves are interengaged with a detent arranged to prevent opening of the valve which controls the rivet feeding mechanism when the valve which controls the jaws is closed.
