A storm window assembly is provided for easy installation upon the exterior surface of the frame of a prime window of a building. The assembly is comprised of four track-like pathways adapted to slideably engage four storm window sashes and a screen sash. The pathways are of progressively larger rectangular perimeter going from the exterior to the interior borders of the frame, thereby permitting easy removal of the sashes for cleaning purposes. The several sashes have about half the height of the frame, and are arranged in a manner to create a dead air space within the assembly. A flange and associated resilient gasket is disposed outwardly from the frame in a manner to permit weatherproof abutment with the frame of the prime window without need for caulking.

A storm window assembly adapted to be installed in abutment with the exterior surface of the frame of a prime window of a building, said assembly comprising: (a) a rectangular frame, the sides of which are comprised of a pair of parallel long jamb members having upper and lower extremities, and shorter header and sill members in facing horizontal disposition at the upper and lower extremities, respectively, of said jamb members, said sides defining interior and exterior borders of the assembly and being comprised of four lengths of an aluminum extrusion having been cut and joined at 45 degree angles at the corners of the frame, (b) first, second, third and fourth storm window sashes of sequentially increasing size, and a screen sash, said sashes being of rectangular shape and having heights of about half the height of said frame measured between the sill and the header, the upper extremities of said sashes having paired laterally directed bearing posts which engage said jambs to permit vertical sliding movement of the sash within the jambs and permit removal of the sashes from the jambs by the manual lifting of the lower extremity of the sashes in the direction of the interior border in pivotal movement about said bearing posts followed by the tilting of the upper extremity of the sash within a vertical plane, the lower extremities of the sashes having paired latch means which slideably engage said jambs, (c) said aluminum extrusion being comprised of: (1) an interior flat border surface, (2) an exterior flat border surface spaced apart from said interior border surface in a plane parallel thereto but displaced therefrom laterally with respect to the long direction of the extrusion, (3) a connecting wall extending between said interior and exterior border surfaces, (4) first, second, third and fourth track means adapted to slideably receive said bearing posts and having lower extremities closed by said connecting wall, and open upper extremities, said first track means lying adjacent said exterior border surface and said second, third and fourth tracks lying in contiguous succession, placing the fourth track adjacent the interior border surface, said succession being a stepwise array wherein each track is laterally displaced from adjacent tracks, and (5) a flange strip disposed on the opposite side of said connecting wall from said track means and disposed between said interior and exterior border surfaces in parallel disposition thereto, (d) the fourth lengths of said aluminum extrusion constituting the sides of said frame being interconnected in a manner whereby the first, second, third and fourth track means of each side are in vertical coplanar alignment, directing the open upper extremities of the track means toward the center of the frame, thereby forming continuous rectangular first, second, third and fourth pathways which accommodate said first, second, third and fourth storm window sashes, respectively, and said screen sash sharing said first pathway with said first storm window sash.
