Abstract

A camming member (50) for power tongs, comprising a ring-shaped body (52) including a central opening (54) formed therein, the body (50) being rotatable about a point (10) within the central opening. A slot (57) in the drive member (53) being alignable with a slot (56) in the body (52). The drive member (53) is rotatable independently of the body (52). A detent and stop mechanism (63) is provided for allowing the body (52) and the drive member (53) to partially rotate relative to one another to a desired engaged position and then to maintain the engaged position as the camming member rotates. The body has a first cam surface (79) curving inward toward the point (10), and a second cam surface (80) curving inward toward the point. At least a portion of the second cam surface (80) being axially aligned with and offset from the first cam surface (79).
