    Abstract: A drive apparatus for reversible movements of an actuator is provided with a drive element made from a shape memory alloy with one-way effect. The drive element acts upon a lever rotatable about an axle in opposition to the force of a resetting element, wherein the lever can be used as a coupling member for converting a deformation of the drive element into a movement of the actuator. The drive element is a winding with a plurality of turns of a wire, wherein the turns are fixed and arranged mechanically parallel between an anchor point and the lever so that the lever is rotatable about the axle by means of a deformation of a turn, and the tractive force acting upon the lever by means of the drive element results from the individual forces of the turns of the winding acting mechanically parallel upon the lever. The diameter of the wire is advantageously approximately equal to the standardised diameter of the crystalline grain of the shape memory alloy in the austenitic state.

    Abstract: A percussion tool such as a hammer head comprises a housing for receiving a tool. A rotary drive mechanism rotates the tool about a longitudinal axis. A strike bolt is arranged for impacting against the tool. A cylinder sleeve is mounted coaxially with the longitudinal axis. A piston is slidable within the sleeve and is arranged to impact against the strike bolt. An impact drive mechanism is provided for imparting sliding movement to the piston toward the strike bolt. The impact drive mechanism comprises a wobble drive member mounted for longitudinal reciprocal movement and for rotary movement about an inclined axis disposed at an acute angle relative to the longitudinal axis. The wobble drive member is operably connected to the cylinder sleeve and to the rotary drive means to be driven thereby about the inclined axis so as to be longitudinally reciprocated. Thus, the rotary forces and impacting forces are derived from the same source.

    Abstract: When the hammer drill spindle and chuck are driven forward with the mode selection collar positioned to allow axial movement of the chuck and spindle, the annular ratchet is driven by the spindle through a one way roller clutch so it rides up the sloping surfaces of the fixed annular ratchet and then drops off the tooth corners to deliver a hammer blow of a magnitude determined by the operator pushing on the tool. If the rotation is reversed the clutch prevents rotation of the clutch input and prevents injury to the operator. If the selection collar is moved to lock the lugs in the detent notch of the cam surface the drill can be rotated either direction with the hammer action always locked out.
