Abstract
This sliding sash drive assembly includes a rack gear for the sash and a drive unit adapted to be mounted on the window frame and having a driven spur gear. An L-shaped engagement lever is mounted at its vertex on the housing and carries on its short leg a rack guide adapted to embrace the rack gear so that, as the long leg of the lever is moved, the guide moves the rack to a position at which the rack meshes with the spur.
