Title: Dual blade wiper

Abstract: There is disclosed a dual blade wiper for a windshield wiper or squeegee in which the wiper is separated along its length into two blade portions except for its ends; at the ends the blade is not separated but at least one of the ends has a slot which communicates with the space between the 2 blade portions; the blade edges are preferably rounded on the ends rather than having the conventional tapered configuration. The construction of the blade, the flexure characteristics of the material and the forces present during motion of the wiper cause the blade portions to separate and come together in the reciprocating action of the windshield wiper, thereby drawing water or moisture into the space between the blade portions and ejecting it from the slot communicating with the space between the blade portions.
