a fixed glass secured to the transom window frame; and
a hinge disposed between the vent glass and the fixed glass, the hinge comprising:
an upper hinge member affixed to the vent glass of the transom window,
a lower hinge member affixed to the fixed glass of the transom window and fixed to the transom window frame,
a hinge cover secured between the upper hinge member and the lower hinge member and engaging the lower hinge member, and
a spring element positioned between the upper hinge member and the hinge cover and acting between the upper hinge member and the lower hinge member,
wherein the upper hinge member includes a first pivot member cooperable with a corresponding second pivot member of the lower hinge member, and wherein each of the upper hinge member and the lower hinge member includes a stop surface that limits a pivot range of the upper hinge member relative to the lower hinge member,
wherein the upper hinge member further includes a first spring seat on a side of the upper hinge member opposite from the pivot member, and the hinge cover includes a second spring seat, the spring element being secured between the first spring seat and the second spring seat, and the hinge cover being secured in position by the spring element urging the hinge cover into engagement with the lower hinge member, and
wherein the upper hinge member is pivotable relative to the lower hinge member between a closed position and an open position, and wherein in the closed position, the spring element is positioned to bias the upper hinge member toward the closed position, and in the open position, the spring member is displaced over center to bias the upper hinge member toward the open position.
9. A transom window according to claim 8 , wherein the first pivot member comprises a rail, and wherein the second pivot member comprises a follower.
10. A transom window according to claim 8 , wherein the hinge cover comprises a stop arm extending from a position adjacent the lower hinge member toward the upper hinge member, a distal end of the stop arm being disposed in a pivot path of the upper hinge member.
11. A transom window according to claim 8 , wherein each of the upper hinge member and the lower hinge member comprises at least one adhesive cavity, and wherein the upper hinge member is secured to the vent glass by an adhesive and the lower hinge member is secured to the fixed glass by an adhesive.
12. A transom window according to claim 8 , wherein the lower hinge member comprises a cover seat shaped substantially corresponding to an outside perimeter of the hinge cover, wherein the hinge cover is positioned in the cover seat.
13. A multi-piece hinge pivotably connecting a top member and a bottom member, the hinge comprising:
an upper hinge member securable to the top member;
