ABSTRACT:
A window sash balance shoe for use in a tiltable window assembly. The window sash balance shoe is capable of adjusting the frictional force between a window sash and the walls of a guide track sufficient to allow said window sash balance shoe to maintain its vertical position in the guide tracks along the range of vertical positions, but insufficient to prevent the window sash balance shoe from being raised or lowered. The window sash balance shoe has a body having a transverse bore within which a friction adjustment cam resides. As the friction adjust cam is rotated it causes the body to expand within the guide tracks. The window sash balance shoe additionally provides a connector for receiving a pivot bar of a window sash and a connector for receiving a tension device or spring. The connector for receiving a tension device is a hook having a notch formed in the convex side of the hook. The notch provides a point at which the end of the tension device can stretch over the hook and rest within the notch.
