Abstract
A pair of sweep locks and a corresponding pair of tilt latches are combined and mounted together on an upper rail of a lower sash. The tilt latches and sweep locks are then interactively engaged so that locking the sweep locks latches the tilt latches, and unlocking the sweep locks leaves the tilt latches latched. Unlocked sweep locks allow manual unlatching of tilt latches, and relocking of sweep locks automatically relatches tilt latches.
