Abstract: A snap-ring pliers for facilitating quick and easy engagement of the jaw portions thereof with the free ends of a snap-ring includes a pair of pivotally connected handles, and a pair of elongate jaws, one of which extends from each of the handles, with each of the elongate jaws defining a groove extending along the length of the jaw. In accordance with one aspect of the invention, each groove defines an elongate base portion recessed into the jaw and ramp portions laterally adjacent each side of the base portion, with the ramp portions being inclined from a face of the jaw toward the base portion of the groove to facilitate engagement of the jaws with the free ends of a snap-ring, even when the ends of the snap-ring cannot be seen. In accordance with another aspect of the invention, the jaws extend from each of the handles along a line which is at an angle relative to the pivot axis and to the plane in which the handles are pivoted.

Abstract: An apparatus and method for manipulating a fastening device such as a bolt or screw is disclosed. The apparatus comprises a handle which has a rotatable shaft inserted through the handle. A housing pivots about one end of the handle. A drive head is located in the housing and has an end which can be adopted to a socket or other device to fit the fastening device. The drive head pivots with the housing as the housing rotates about the handle. The longitudinal axis of the drive head can be aligned with the drive shaft, or the housing and drive head can be pivoted about the handle until the longitudinal axis of the drive head is perpendicular to the drive shaft, and a drive gear mechanically connects the drive shaft to the drive head. The drive shaft can be rotated to manipulate a fastening device at angles of 0.degree., 90.degree., and 270.degree. from the drive shaft.
