Claim:
A window operating system for use with a casement or awning window, said window having a frame and a sash, said sash being movable between a closed position and an open position, said system comprising at least one actuator located on one side of said frame and operable to open and close said sash, the at least one actuator having a universal screw, said actuator functioning as a hinge as well as an actuator, a hinged support on said frame on a side directly opposite to said actuator, a crank assembly mounted on said frame, said crank assembly having a crank extending therefrom on an inner side of said frame, said crank assembly being located on said frame at a different location from said actuator, said crank being rotatable in one direction to operate said actuator to open the sash and in an opposite direction to operate said actuator to close said sash, there being at least one lock mounted on said frame with a keeper for each lock being mounted on said sash, said at least one lock being connected into said system to be operated by said crank to lock said sash within said frame in a fully closed position and to open said at least one lock to allow said sash to move from said fully closed position to a fully open position, wherein said at least one lock has a universal screw that is connected to rotate as said crank rotates, said actuator and said at least one lock being synchronized to operate in sequence, wherein said actuator, at least one lock, and crank assembly are individual modules connected to be operated by said crank, said crank being a single crank, wherein said at least one lock has a disk that is pivotally mounted on said at least one lock with a pivot arm being pivotally mounted on said disk, said pivot arm being pivotally connected to a clasp that is pivotally mounted on said at least one lock to release and receive said keeper as said crank is rotated, said disk being connected to pivot as said universal screw of said at least one lock rotates, thereby causing said pivot arm to pivot relative to said clasp and causing said clasp to pivot to release or receive said keeper of said at least one lock respectively, and wherein the pivot arm pivots relative to the disk and the clasp pivots relative to the at least one lock.
