A compact, internal-external gripper apparatus for use with an industrial robot utilizes a sliding block actuated toggle linkage to apply an input force to a pair of finger supports in a fully enclosed housing. Pressure is selectively supplied to each end of the sliding block to reciprocably move it along an internal way system with a unidirectional spring assist in the workpiece clamping position.
