  • Apparatus for mounting and stabilizing a tiltable window sash
    Patent number: 4644691
    Abstract: A window sash is mounted for downward and inward tilting by a pair of grooved spools which project laterally into channels formed in the side jambs of the window. The grooves in the spools track along vertical ribs formed in the channels and normally move freely along the ribs to permit free up and down movement of the sash. When the sash is tilted downwardly and inwardly, the side walls of the spool grooves frictionally pinch the ribs to restrict up and down movement of the sash and to help stabilize the tilted sash.
