SCREEN CURTAIN Application and February 20,1928; "SerialNo, 255,546.

My invention relates to Windowscreens 1 Against thetop 9 of thewindow' frameis which serve to protect buildings against the entry of mosquitoesand similar vermin and fthe objects of my invention are, first, to have *the screen, conveniently, on the inside of the window, second, to be able to remove it by I an operation as simple as that of lowering and raising a window shade, third, to have the window completely protected by the 1o screen, when it is closed, so that no objectlonable insects can enter at any point of the Window, fourth, to allow thevuse of a screen which can be washed-and kept clean like i o) any other cloth fabric, fifth, to provide a screen which can be .made attractive and which, in colorand design, can-be kept in harmony with the interior decorations, sixth, to have a screen that does not requlrejmount- Zing and dlsmounting between seasons, and

'seventh, to have the screen completely re-- .gmoved from sight and protected from dirt when it is not in use. i V y To attain these objects I use the mechanism .and arrangement illustrated in the accom-v panying drawing in which: V
