Abstract
A locking system for a window sash comprises a lock handle assembly, reciprocating rod members connected to the lock handle assembly, and rotatable cam assemblies connected to the rod members. Each cam assembly has a cam element which upon reciprocation of its respective rod element moves into and out of a cam keeper which is mounted on an adjacent window sash. Each rod member has a rod tip which moves into and out of a channel provided in the window frame. In a first operation of the lock handle assembly, the rod members are reciprocated inwardly to rotate the cam elements out of their respective cam keeper and to move the rod tips partially out of the frame channels which allows the window sash to be moved vertically within the channels. A further operation of the lock handle assembly moves the rod tips entirely out of the channels to allow the window sash to be tilted.
