A headlamp wiper assembly, for spraying and wiping headlamps including one or more wiper arms and blades fixed to pivot about a common axis with the wiper blade consisting of a backing strip having key slots therein and an open aperture at one end, along with a multifarious wiping element having a plurality of T-shaped projections for fitting in the key slots in the backing strip and a projection at the end thereof for buttoning the backing strip to the wiping element upon stretching the wiping element. The wiping element is provided with a plurality of angularly related wiper facets for engaging with and cleaning the headlamp. The assembly is provided with a drive shaft interconnected to oscillate the wiper arm and blade through a bracket assembly, the end portion of the drive shaft being provided with a nozzle means having one or more openings and oscillates with the wiper arms and blades and sprays the headlamps adjacent the wiping element as they oscillate. The assembly is provided with crank assembly for translating the rotary motion of a motor to the necessary oscillating motion of the drive shaft to drive the wiper arms and blades through one or more wiping cycles. The angularly related wiper facets on the wiper blade lay over in overlapping relationship in a trailing position with respect to the washer spray to more effectively clear the headlamp surface. |
