Abstract: A telephone booth wherein the sidewalls are box-like enclosures each having one or more advertising displays. The displays are illuminated by a light source located in the interior of each enclosure and the same light source also serves to illuminate the interior of the booth. The sidewall enclosures have an openable panel which permits the advertising displays to be changed from time to time as well as permitting access to the light source.

Abstract: 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.

Abstract: A safety release closure suitable for use in a mass transit vehicle which can be rapidly and efficiently removed either inwardly or outwardly in case of an emergency. The closure includes a removable sash that is mounted within a frame opening and secured in place by means of inside and outside deformable seals disposed between the frame and the inside and outside margins of the sash. The perimeter walls of the opening that face the sash are contoured so that the opening is wider across both edges than it is along the middepth region whereby the sash can be easily removed in both directions without it becoming wedged or otherwise jammed in the frame. Means for stripping the seals on both sides of the sash are provided for as are handle means which enable a person to pull the sash out of the frame after the seal has been removed.
