Abstract

676,930. Windows. PERRY, A. E., PERRY, M. G., and PERRY, J. V. Sept. 8. 1950, No. 22182/50. Class 20(iii). In a double hung sash window the upper sash 5 is connected to the lower 6 at each end by a spring 12 and flexible member 14 passing over a stationary pulley 15. When both sashes are fully closed, as shown, the springs are tensioned and it is necessary to lock the lower sash to the sill by a catch 18. On release of the catch the lower sash rises until the tension in the spring is relieved whereupon the lower sash remains in that position and the upper sash remains closed. Thereafter the sashes balance one another and as the lower is raised the upper is lowered. The upper sash can be held open independently of the position of the lower sash by means of a detent.
