Claim:
1. A latch for a tilt window comprising a locking mechanism with a rack defining proximal and distal ends and comprising a plurality of teeth positioned between the ends, the rack proximal end connected to the locking mechanism, a bolt affixed to the rack distal end for securing the window within a sash; the locking mechanism including a handle defining a post, a gear defining a post and a plurality of teeth, the gear post offset relative to the handle post, a cam having a timing device formed on an exterior surface thereon, the cam frictionally contacting the gear via the gear post, whereby manually engaging the timing mechanism produces adjustable rotation of the cam and the gear, resulting in cooperative enmeshing of the rack teeth with the gear teeth, whereby rotating the handle from a first position to a second position causes corresponding rotation at the cam and the gear, and whereby rotating the handle from a second position to a third position causes the gear to retract the bolt, the handle orientation at the second position different from the handle orientation at the third position.
