An improved linkage mechanism for the opening and closing of a transom-type window, allowing for the window sash to fit tightly within the window frame in a closed position while, on the other hand, allowing for maximum open space for escape through the window frame when the window is opened. A tight fit between the sash and frame of the window is accomplished by having flanges on the sash and linkage means which causes the window sash to be first translated away from the window frame upon opening, providing enough clearance for the window to then be pivoted to an open position on a pivotal axis disposed away from the frame. The linkage is also designed to allow for maximum open space for individuals to escape through the window frame in an open position and a latch mechanism for holding the window in the full-open position for escape.

An improved linkage supporting and positioning a window sash in relation to a window frame, comprising: a window frame track member which is affixed to said window frame; a moveable sash support member upon which the window sash is attached; an upper linkage means having one end pivotally connected to said frame track member and the other end pivotally connected to said sash support member; a slide, slidably connected to said frame track member; a lower linkage means having one end pivotally connected to said slide and the other end pivotally connected to said sash support member at a joint removed from the connection of said support member with the upper linkage means; a stabilizing linkage pivotally connected on one end to the frame track member and on the other end to the lower linkage means; and whereby the window sash affixed to said moveable support member is both translated away from the window frame and pivotally rotated to effectuate the opening and closing of said sash in relation to said window frame allowing for both tight sealing upon closing and a maximum escape opening per length of a window frame, upon opening.
