An integrally-formed sash portlight for installation through a side-wall opening in the cabin or hull structure of a marine vessel has an inwardly-projecting, rectangular, spigot portion within which a rectangular light or screen can be selectively fitted. The spigot portion is provided along the inside top with a side-to-side groove within which an upper marginal edge portion of either the light or framed screen can be received, selectively, and along the inside bottom with a vertically opposed side-to-side seat for the seating reception, selectively, of a lower marginal edge portion of the light or screen, said seat being angularly inclined along its length in the downward direction from inside to the outside, and said lower marginal edge of said light and screen being beveled to the same angle as said seat so as to be in substantially face-to-face contact therewith upon installation in the portlight frame, whereby water impinging on the outside of said light when installed in the portlight frame will be shed downwardly and outwardly of the vessel in which the portlight is installed.
A sash portlight for marine use, comprising, in combination, a rectangular frame member, said frame member being integrally formed with a tubular spigot portion defining a rectangular through opening, said tubular spigot portion having integrally formed therewith, about its outer periphery, a perpendicularly-outwardly-extending flange, a rectangular sash light receivable within the said rectangular through opening, said flange comrising a perpendicularly-inwardly-extending top portion and opposed perpendicularly-inwardly-extending side portions serving as abutment surfaces for marginal outer surface portions of said sash light upon installation in said frame member, means defining a longitudinal groove at the inside upper wall portion of said spigot portion and comprising said perpendicularly-inwardly-extending top portion of said flange, means along the inside lower wall portion of said spigot portion and extending upwardly thereof for seating a lower marginal end portion of said rectangular sash light upon its installation in said frame member, said seating means being vertically opposed to said longitudinal groove means, the width of said longitudinal groove and the top-to-bottom overall height of said sash light being such as to permit the insertion of an upper marginal portion of said light upwardly within said longitudinal groove and a lower marginal portion thereof over said seating means for placement in abutment with said abutment surfaces and, after subsequent downward movement, in abutting engagement with said seating means for the retention in place of said sash light in said frame member, said seating means comprising a rectangular upper end portion merging, at the outside, with a longitudinally-extending, downwardly and outwardly-directed, beveled surface portion extending through to the outer surface of the bottom portion of said flange, said sash light being beveled along its lower edge to define an angle of inclination substantially equal to that of said beveled surface portion, whereby, upon the seating of said sash light in place upon its installation in said frame, its beveled edge will seat face-to-face in abutting engagement against said beveled surface portion of said seating means.
