A wiper assembly for wiping a circular or convex surface such as that of a headlight, search light, or side mirror of a vehicle, having an annular member mounted outwardly adjacent to and coaxial with a periphery of the surface, a pivot shaft rotatably mounted outwardly adjacent to the surface, a wiper arm attached to the pivot shaft and extending into the annular member, the extremity of which is oscillable within the annular member, a spring-hinge holder attached to the oscillating end of the wiper arm, a resilient wiper blade which is held by the spring-hinge holder and caused thereby to conform to the surface at all times and to the inner perimeter of the annular member when the wiper arm is at or near a limit of its oscillation, and a means of oscillably driving the pivot shaft. |
