Antifreeze self-spraying and -warming windshield wiper

A wiping member for sweepingly cleaningly engaging a windshield pane of an automobile and for use with power means which laterally displace said wiping member over said windshield in a cyclic back and forth movement, said wiping member including:

• (a) an elongated bead, to cooperate with said power means;
• (b) an elongated blade, integrally dependent from said bead and defining two transversely spaced lips forming a lengthwise first channel therebetween, said first channel being generally U-shape in cross-section and defining a first flooring, merging with said bead and interconnecting said lips, the free end tips of said blade lips defining therebetween a first mouth opposite said first flooring, said lips being resilient for bendingly yieldingly engaging said windshield transversely at their tips;
• (c) an elongated, thermally conductive casing, being of generally U-shape in cross-section and enclosed within said first channel and directly contacting in operative position said lips and said first flooring, said casing defining two side legs and a second flooring interconnecting said side legs thereof, a second elongated channel defined between said casing side legs, a second mouth defined by said second channel between the tips of said casing side legs opposite said second flooring, said second mouth extending short of said first mouth whereby said second channel opens into said first channel through said second mouth;
• (d) heat generation means attached to said casing for heating said casing;
• (e) first securing means, to fixedly secure said casing within said first channel in its said operative position;
• (f) a fluid pipe, enclosed within said second channel and directly contacting in operative position said second flooring and side legs;
• said pipe to be force fed with a heat-vector fluid, said pipe including a number of radial through-bores for through passage of said force-fed fluid from said pipe transversely radially outwardly therefrom;
• said radial through-bores being in register with said second mouth to open therethrough, into said first channel, for fluid escape therefrom through said blademouth toward said windshield;
• and
• (g) second securing means, to fixedly secure said fluid pipe within said second channel in its said operative position;
• wherein said casing and said fluid pipe extend for substantially all the length of said wiping blade;
• said bead, blade and pipe are each made from a heat-conducting material;
• wherein upon energizing of said heat-generating means said casing and subsequently, said fluid pipe, blade and bead are concurrently warmed, for wiping member use in sub-freezing climates.
