Abstract

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.

Claims

1. A wiper assembly for wiping a surface of circular convex shape, comprising:

an annular member with an inner diameter greater than the peripheral diameter of the surface and adapted to be disposed concentric with the surface;

a wiper arm, means oscillatably moving said wiper arm between two limiting pOsitions on the inner perimeter of said annular member;

a resilient wiper blade provided with two pins spaced longitudinally thereof; and

a holder spring hinge connected to said wiper arm and having formed therein a hole and a slot, said holder receiving said two pins in the hole and slot, respectively, for permitting limited rotation of said resilient wiper blade with respect to said holder and biasing said resilient blade to the surface.
