Abstract
A locking and dead bolt locking device associated with the upper rail or frame portion of a window or door sash slideable in a fixed frame, having a latching arrangement engaging a horizontal rail portion and a dead bolt arrangement engaging the frame and mounted on an upper portion of the sash. The latching arrangement includes a tongue latch portion operable normal to the plane of the window and with the dead bolt being integrally carried thereby. When closed, the tongue portion of the latch engages a striker plate of said rail while the deadbolt is engaged with the frame to prevent opening of said latch. Simultaneously, the sash is secured with respect to the frame thereby providing a dual means for securing the sash in a close position in said frame.
