ABSTRACT:
A power-operated riveting tool which includes a unidirectional rotational power source having a rotational output along a rotation axis; and a power-driven riveting attachment for mounting onto the rotational power source, wherein the riveting attachment includes rivet holding and pulling apparatus mounted for axial translation along a work axis between extended and retracted positions, the rivet holding and pulling apparatus having a rearwardly extending threaded shank integrally formed therewith, the rivet holding and pulling apparatus being restrained from rotation about the work axis; transmission apparatus for selectable operation by the rotational power source, and threadedly engaged with the threaded shank along the axis, operation of the rotational power source causing rotation of the transmission apparatus about the work axis in a first direction, thereby to cause a linear translation of the threaded shank and thus the rivet holding and pulling apparatus along the work axis in a corresponding first axial direction, from the extended to the retracted position; and windable resilient return apparatus associated with the transmission apparatus and which, when the rotational power source is operated so as to rotate the transmission apparatus, is operative to be wound, and which, when the transmission apparatus is disengaged from the rotational power source, is operative to rotate the transmission apparatus in a second, reverse direction, thereby to cause a corresponding linear translation of the rivet holding and pulling apparatus in a second axial direction, thereby to return the rivet holding and pulling apparatus from the retracted to the extended position.
