Abstract: A window frame assembly made of hollow profiles where the components are welded together to form a channel or passage for a balance shoe, wherein the balance shoe is characterized by having the side walls of the balance shoe recessed so as to accommodate flash that may be encountered at the weld seam of the welded components.
Abstract: A pivotable window sash assembly includes a pivot bar which engages a balance shoe for holding the sash to a master frame. The shoe has a recess in which a locking member is rotatably mounted. The locking member includes an exposed keyway which is selectively aligned with at least one slot in the shoe located at the recess. The pivot bar has an arm which functions as a key for fitting in the keyway and has at least one projection extending outwardly from the arm for fitting in each slot when the slot and keyway are aligned.
