Abstract
A screen wiping apparatus comprises a crank which is coupled through a pivot pin to a crank arm, which may for example be part of a screen wiper arm, the pivot pin providing an articulation between the arm and the crank whereby to provide non-circular wiping. The pivot pin has a head joined by a first cylindrical portion to a second cylindrical portion of smaller diameter than the first, the head and the two cylindrical portions being coaxial with each other. The first cylindrical portion of the pivot pin passes through a sleeve fitted transversely in the crank, while the second cylindrical portion extends through the crank arm. At least one ring carried by the crank is immobilised against rotation with respect to the crank.
