Abstract
A latch assembly for double hung windows also permits each of the sashes to be tilted inwardly with respect to the window frame assembly. The window latch assembly includes a keeper which is recessed within a lower rail of the upper window sash, and a latch which is recessed in the upper rail of the lower window sash and positioned such that the latch and the keeper are selectively engaged upon rotation of a sweeper cam. The sweeper cam also engages a slide translatable between a first position engaging one of the side rails of the window frame assembly, and a second position, retracted within the lower window sash and release the upper edge of the window sash from the window frame assembly.
