Patent number: 4134234Abstract: This invention relates to an improved weather strip and balance assembly for nonremovable windows in which the weather strip is made of a compressable, high impact material with ridges thereon to mount the sash. The ridges also mount and enclose the balance springs and pulley blocks with the sash cord coupled thereto for counter-balancing the weight of the sash. The sash cord is directed out from behind the weather strip through an opening therein to connect to the sash through an anchor. The length of the sash cord at the connection of the sash is adjustable to adjust the tension of the balance system applied to the sash. The assembly is readily assembled in said jambs of a window frame by securing the same thereto, such as by screws. The assembly is manufactured, shipped and stored without tension thereon to eliminate warpage and displacement of parts.Type: GrantFiled: February 2, 1978Date of Patent: January 16, 1979Assignee: Celotex CorporationInventor: Edward H.
