ABSTRACT:
A windscreen wiper drive linkage has a wiper blade mounted on the end of a blade arm by means of a pivotal connector allowing shifting of the position of the blade relative to the end of the arm in a radial direction relative to the center of rotation of the arm. Such radial shifting of the blade is actuated by a second arm pivoted at one end of the blade-carrying connector and at the other end to an actuating crank which is driven by a pivotal arm linkage from a drive crank to the main blade arm. As the drive crank rotates in a to-and-fro manner the linkage, comprising two reversing links pivotally attached to an idler, drives the actuating crank for rotation to displace the blade radially relative to the center of rotation of the blade arm.
