Abstract
A balancing arrangement for double hung windows is disclosed including a spring arrangement supported by a spring holder installed in a window jamb and a balance shoe installed in a window sash. A leaf spring is supported to engage a detent in the balance shoe installed in the top window sash, whereby displacement of the top sash when closed is prevented to maintain the seal between the bottom and top sashes at the horizontal center of the window when the bottom sash is lowered for closing against the compression force of a weather stripping seal at the horizontal center. The opening of the top sash is unaffected, other than a slightly greater force being required to bypass the leaf spring and detent arrangement.
