Abstract
A fine angular adjustment is provided between a windshield wiper arm and a windshield wiper drive shaft without changing the standard drumhead or drive burr carried by said drive shaft. Provision is made for fine adjusting the angular orientation of the arm by increments of one degree. In two embodiments, the mounting head of the arm is in two parts with the first part fixed to the drumhead of the drive shaft and the second part having incremental teeth being spring urged into contact with mating incremental teeth on the first part, such that actuating the spring separates said incremental teeth of the two parts making it possible to rotate the second part relative to the first part in approximately one degree increments. Another embodiment provides for offset openings in the mounting head with flutes in each opening being offset from a centerline a predetermined amount such that assembly of the mounting head on a drumhead in one or the other of said openings will provide the arm with one degree increments of orientation.
