As soon as the stiffeners reachthe position shownigi'2,-they would jamagainst the upper bar of the window frame and a further winding of the shade would become imposslble. It is, therefore, obvious-that should the operator of the window shade lose his grasp on the pull cord-and allow the shade totravel up the window unchecked, it would stop as soon as the stiifeners came Contact with the-upperbar ofthewindow frame. this c i e i new p bli y he new of supplementary or additional, stiffeners,

With a View to remoying the stiifeners from t e h e o de to e ean he lat e ew -y Wither iew to epla g h tiffen in a' new shade, the shade has bgQILPI'GVidQd with a slit l4 intheglower edge of the bottom 11mm wh chsl t,ex e dsr nwa d y t ch: en

'By positioning one of such devices in the'center of the bottom edge of the shade or, at either endof the same, it is apparent that when theshade reaches the raised position, the member 18 will wedge between the bottomedge of the upper bar of the window frame and the top of theishadeiroller, thus preventing the further winding of the shade.

It is further apparent that this device niightibe fdiiined of a material inherently resilientin itself so as to make the insertion of the res-ilient member 17 unnecessary.
