Abstract

A double hung window has upper and lower window sashes in a window frame including a header, sill, and a vertical jamb on each side. The upper sash is pivotally connected to the frame header for inward pivotal movement on a horizontal axis. The lower sash is pivotally connected to the upper sash for reverse pivotal movement on a parallel horizontal axis, whereby to fold the lower sash up and under the upper sash. A tape balance atop the frame applies a lifting force to the lower sash. Grasp and inward pull of a handle pulls lower and upper sashes inward from a dead center condition, thereby enabling the tape balance to effectively assist in pulling the sashes upward. A screen, separate from the window sashes, is removably mounted on the outer face of the window frame.
