Abstract
A wiper drive assembly (20) disclosed is particularly adaptable for use with angularly skewed vision blocks (22) of an armored car. A hollow guide (28) of the assembly includes elongated first and second guide portions (30,32) that are adapted to extend alongside the vision blocks and which receive respective first and second wiper supports (70,104). Each wiper support has an extension that projects through a slot in the associated guide portion so as to allow mounting of the arm of an associated wiper (24,26). One of the wiper supports has its extension provided with a slidable connection (86) to a continuous drive loop which is preferably in the form of a chain (34) received by a pair of sprocket type sheaves (36,38). Driving of one of the sheaves moves the chain so as to drive the first wiper support (70) in a reciprocal manner. An elongated connector of the drive assembly is preferably embodied by a wire (118) that extends between the first and second wiper supports within the guide portions in a guided relationship so as to move the second wiper support (104) along with the first wiper support in a reciprocal manner.
