Combination sash lock and tilt latch and slidable window vent stop
A sash window fastener includes: a latch assembly; a lock assembly mounted upon the meeting rail; and a stop assembly mounted to the master frame. The lock assembly includes a pivotable cam to engage a keeper on the master frame to lock the window, and a pivotable follower arm, which interconnects with the latch assembly within the meeting rail, so cam rotation that drives arm rotation also causes translation of the latch. The cam occupies: an extended position to secure the cam to the keeper, with the latch tongue engaging the master frame to prevent tilting, also being positioned below a stop assembly protrusion to redundantly lock the window; a first retracted position permitting sliding of the window; and a second retracted position permitting tilting of the sash window. A slidable stop on the stop assembly dampens sliding sash window movement and subsequently acts as a vent stop.
