Abstract
Abstract A removable window applicable to single or plural hung sash designs and particularly to metallic construction. The window includes a casing having jamb channels in which are positioned balance assemblies to be rigidly positioned therein with respect to translational or longitudinal movement. The sash rides on the surface of the balance assembly through guide members which are deformable and the opposite edges of the sash include lower guides which are positioned in the jamb channels remote from the balance assemblies to be guided therein. The sash cords of the balance assemblies have hooks which ride beneath the lower guide means on the sash which hook is turned with pivoting of the sash on the lower guides to lock the sash cords in position in the jamb channels as the window is removed. The sash are removed by pivoting the window away from the balance assemblies through the deformable guide means at the upper edge and tilting the sash to release the lower guides from the jamb channels. Weatherstripping on the window casing and on the sash seal the edges of the sash and the tops and bottoms of the same to provide an airtight window assembly.
