ABSTRACT:
A tool handle assembly embodying an axially-extending torque-applying tool shank disposed for axial and rotative movement in a double-spring clutch in a handgrip. The clutch consists of two axially-aligned springs disposed in opposite ends of a chamber formed in the handgrip. The shank is movable axially within a connecting sleeve arrangement provided between the shank and the springs and the springs and the handgrip which is such that when the shank is selectively moved to one extreme axial position and the handgrip is turned, the one spring clutch will apply torque to the shank and permit free reversal in the opposite direction; when the shank is selectively moved to its other extreme position and the handgrip is turned, the other spring clutch will apply torque to the shank in a reverse direction and permit free reversal in the opposite direction; and when the shank is selectively moved to an intermediate position one spring clutch will function to apply torque to the shank when the handgrip is turned in one direction and then the other spring clutch will function to apply torque when it is turned in the opposite direction, there being no free-reversal.
