ABSTRACT:
These tools efficiently and rapidly remove a snap ring and clips by initially applying a torque thereto along the length of the flat portion of the clip or along the annular length of the ring. When such rings and clips are thus stressed to a limited degree they exhibit resilient twisting or torsion about such axis. The tools are adapted to then displace the portion of the smap ring or clip that provides a locking action on the groove to which the ring or clip was attached in a direction in part at least perpendicular to the wide flat surface of the portion of the snap ring or clip in the vicinity of that then resiliently twisted portion of the ring or clip and so move that portion of the ring that initially provided locking action on the groove therefor in a direction parallel to or along the wider initial plan or surface of the snap of the snap ring or clip surface. Such movement controllably and readily disengages the locking portion of the snap ring or clip. The ring or clip is then controllably moved transversely to the plane of the flat surface thereof to completely remove the ring. The tools also serve to similarly control such snap rings or clips during installation thereof.
