1. A mechanism adapted for controlling the reciprocating movement of a first planarly slidable window panel and a second planarly slidable window panel with each panel independently slidable between fully raised, lowered and intermediate positions independently of one another within a common sliding plane, said mechanism comprising a first rotatable operating arm and means for changing rotational movement of said arm into reciprocal movement of said first panel, a second rotatable arm and means for changing the rotational movement of said second arm into a reciprocal movement of said second second panel, a common pivotal shaft for both said arms, a sector gear secured to each arm, for causing rotation of the respective rotatable arms on rotation of said sector gears, both said sector gears mounted for rotation independently of one another on said common pivotal shaft, and means for driving each sector gear independently of the other sector gear to reciprocate the windows independently of one another, each said driving means including a pinion gear in mesh with a respective one of said sector gears, and a unitary structural plate for mounting said pinion gears and said common pivotal shaft, and wherein said unitary structural plate is configured to secure said entire mechanism to a flat wall, said plate including a central socket area for said pivotal shaft, said wall and opposed sockets spaced from said shaft for said pinion gear mountings.
