Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A cowl mounted windshield cleaner assembly comprising: an elongated casing formed of two longitudinally extending, substantially symmetrical, integral half shells having planar mating surfaces, each half shell comprising a unitary member having an open semicylindrical chamber intermediate its ends and an open box-like chamber at each end, the semi-cylindrical chamber and the box-like chambers of each half shell being open to the planar mating surface of the respective half shell, the two half shells in assembled relationship having the several chambers aligned with each other to form a closed cylindrical chamber intermediate the ends of the casing and closed substantially box-like chambers at each end thereof, a drive motor positioned in the cylindrical chamber and having a drive shaft projecting from each end thereof and extending into the end box-like chamber, windshield wiper blade oscillation means supported in each box-like chamber, and drive means contained within each box-like chamber interPosed between the motor and oscillation means to drive the latter in wiper blade oscillation movements.
