This invention'relates to a window opener and one object of the invention is; to provide a device of this characten-by meansv of which either an upper or a lowersash may be, easily i 5 moved in an opening direction. It often hap pens that a window sash will be purposely fitted very tightly in its frame' or becomes swollen during damp weather and cannot be readily opened but by employing; a device 1 such as illustrated in the accompanying drawings either an upper or a "lower sash maybe easily moved in an opening directlon. Another ob ect of the inventionis to so or inarring the sash or adjacent portions of a window frame.
