The first member is adapted to be mounted so that it may be driven in reciprocating manner about a pivot.

Claims5
A windscreen wiper mechanism comprising a wiper arm including first and second members mounted with respect to one another so as to permit axial movement of one member relative to the other to vary the length of the arm, mounting means being provided on said first member by means of which the arm may be secured to one end of a pivot by which it may be driven in reciprocating manner, and means being provided on said second member by means of which a wiper blade may be attached, a cam being mounted in fixed relationship to said pivot adjacent said end of the pivot and a fluid operated means being mounted upon the arm for movement therewith, said fluid operated means being controlled by a cam follower which when the arm is mounted on said pivot engages and follows the cam as the arm is moved on the pivot, said fluid means controlling axial movement of the second member relative to the first.
