Abstract: A window construction having slidable and swinging hinged sashes is disclosed. The pivot arrangement for each sash is constructed for swinging of the sash about a vertical axis. Each sash is usually confined within the frame of the window by a pressure urged sash balance. The sash balance is constructed so that the sash may be moved against the sash balance to position it for swinging away from the frame. A removable T-shaped locking element is received in a channel provided in the jamb adjacent the pivot arrangement of the sashes. One member of the pivot arrangement is disposed within the jamb and has a vertical pivot pin formed thereon. The other member of the pivot arrangement receives one edge of the window pane and has a receptical complementary in shape to the pivot pin. The inner member of the pivot arrangement has a tab portion which cooperates with the locking element to keep the sash secured to the frame. Removing the locking element permits removal of the entire sash from the frame.
