15,008. Hagedorn, W. June 28, 1911, [Convention date]. Theatrical appliances.-Pictures are projected by a kinematograph f on to a translucent screen c, in front of which a plate-glass sheet a is placed. Wings g and front scenery k are placed, as shown, in front of the glass sheet, so that the screen c is viewed through openings in the scenery. The wings g have scenery painted on the back as well as on the front and the back is strongly illuminated. Thus the spectators see this scenery on the back of g by reflection in the plate a, and the figures on the screen seem to be moving about between the wings g and other wings apparently at m.
