ABSTRACT:
Disclosed is a multiple position window latch which includes a latch housing attached to a top rail of a window sash. A stem extends through the latch housing and a latch handle is positioned above the latch housing and is attached to an upper end of the stem. A sweep cam is positioned within the latch housing and is attached to the stem. The sweep cam rotates into and out of the latch housing and engages a keeper on an adjacent window sash. An elongated slide is positioned beneath the latch housing and extends within the top rail toward an adjacent side of the window sash. A driving member on the stem, such as a plurality of gear teeth around a lower end thereof, engages a driven member on the slide, such as a plurality of gear teeth forming a slide. Rotation of the stem by the latch handle moves the slide within the top rail between a first position where a nose of the slide extends beyond the adjacent side of a window sash and into a locking hole in the window frame and the sweep cam is engaged with the keeper, thus locking the window sash in place, and a second position where the nose of the slide is removed from the locking hole and the sweep cam is removed from the keeper, thus allowing the window sash to be moved within the window frame.
