A release mechanism for a vehicle escape sash employs a latch mechanism of novel construction, with parts configured as keeper, hinged latch member, and sash bar. The keeper has a keeper flange that projects upward from a web of the keeper, and has a generally cylindrical undercut recess at its juncture with the web. The recess defines a latch seat. The latch member has a sash plate mounted to the window sash rail and a latch plate hingedly connected to the sash plate. A depending flange on the latch plate has a cylindrical head at its free end that fits into the keeper recess and makes continuous rolling contact therewith when the keeper and latch member are latched together. The sash bar is mounted onto the latch plate and extends inwardly over the latch member, the keeper, and the sash subframe. The sash bar both serves as a cover and as a release handle.

Bus window release mechanism

A multi-glazed window unit of the type wherein parallel panes of a light transmitting material are sealed in a spaced apart relationship and the atmosphere between the sealed panels is treated to remove moisture therefrom. A housing containing a desiccant is positioned between the sealed panes along one outer edge of the unit. The housing is divided into two zones, the first zone being open to the atmosphere so that any moisture present in the atmosphere at the time the unit is sealed is immediately removed therefrom by the desiccant in this zone, and a second zone that is shielded from direct exposure to the atmosphere whereby the desiccant in this zone remains in a condition to remove moisture from the atmosphere which may penetrate the seal at a later time.
