Window construction

Claim 2

A window construction for mounting in a generally rectangular building wall opening having upper, lower and side bounding surfaces; said window construction comprising a generally rectangular frame for approximate conforming location in said opening; said frame including a pair of side members for extension along said side bounding surfaces and upper and lower members for extension along said upper and lower bounding surfaces; a pair of inner and outer flanges on each of said side members extending toward the adjacent side bounding surface, width compensating angle bars extending along each of said flanges and having an edge groove in one wall adjustably receiving the associated flange for movement of its other wall into facing engagement with the adjacent side bounding surface, and a thickness compensating strip extending along each of said angle bars and having an edge groove adjustably receiving the other wall of the adjacent angle bar for movement along the adjacent side bounding surface toward and away from said frame.

Claim 3

A window construction according to claim 1, in combination with a channel-shaped top piece engaged about said upper frame member and vertically adjustable thereon for movement toward the upper bounding surface of said wall opening.

Claim 4

A window construction according to claim 1, in combination with weather stripping carried by each of said angle bars on its other wall for interposition between the latter and the adjacent side bounding surface.

Claim 5

A window construction according to claim 1, in combination with a lower height compensating strip of angular cross section haviNg one strip wall secured to the lower frame member and the other strip wall in facing engagement with the lower bounding surface of said building wall opening.

Claim 6

A window construction for mounting in a generally rectangular building wall opening, having upper, lower and side bounding surfaces; said window construction comprising a generally rectangular frame for approximate conforming location in said opening; said frame including a pair of side members for extension along said side bounding surfaces and upper and lower members for extension along said upper and lower bounding surfaces; a pair of inner and outer flanges on each of said side members extending toward the adjacent side bounding surface, width compensating angle bars extending along each of said flanges and having an edge groove in one wall adjustably receiving the associated flange for movement of its other wall into facing engagement with the adjacent side bounding surface, a thickness compensating strip extending along each of said angle bars and having an edge groove adjustably receiving the other wall of the adjacent angle bar for movement along the adjacent side bounding surface toward and away from said frame, a lower height compensating strip of angulate cross section having one strip wall secured to the lower frame member and its other strip wall in facing engagement with the lower bounding surface of said building wall opening, and a channel-shaped top piece in embracing engagement about the upper frame member and vertically adjustable thereon toward the upper bounding surface of said building wall opening.

Claim 7

A window construction for mounting in a generally rectangular building wall opening, having upper, lower and side bounding surfaces; said window construction comprising a generally rectangular frame for approximate conforming location in said opening; said frame including a pair of side members for extension along said side bounding surfaces and upper and lower members for extension along said upper and lower bounding surfaces; a pair of inner and outer flanges on each of said side members extending toward the adjacent side bounding surface, width compensating angle bars extending along each of said flanges and having an edge groove in one wall adjustably receiving the associated flange for movement of its other wall into facing engagement with the adjacent side bounding surface, a thickness compensating strip extending along each of said angle bars and having an edge groove adjustably receiving the other wall of the adjacent angle bar for movement along the adjacent side bounding surface toward and away from said frame, a lower height compensating strip of angulate cross section having one strip wall secured to the lower frame member and its other strip wall in facing engagement with the lower bounding surface of said building wall opening, and a channel-shaped top piece in embracing engagement about the upper frame member and vertically adjustable thereon toward the upper bounding surface of said building wall opening.

Claim 8

A window construction according to claim 5, said top piece comprising a top wall for facing engagement with the upper bounding surface of said building wall opening, inner and outer walls depending from said top wall on the inner and outer sides of said upper frame member, a lower flange on the lower edge of one of said inner and outer walls extending toward said upper frame member, and a lip on said lower flange extending obliquely upwardly and away from said frame, said top piece being integrally fabricated of resilient material for gripping engagement with said upper frame member.
