Abstract
One-piece member with a cam-shaped periphery serves as both a slide and a tilt-lock for a window sash which is slidable vertically in a window frame and is tiltable with respect to the window frame. A thin, flat, elongated spring leaf has its lower end attached to the combined slide and tilt-lock member and has a spirally wound upper end fastened to the window frame. The window frame conceals and protects the unwound length of this spring.
