Window frames.-A fireproof projecting room for kinema theatres is provided with projecting and viewing apertures closed by transparent fireproof windows having inclined edges so as to form smoke-tight joints, the windows being hinged to open inwardly and having safety shutters. The apertures 2 in the front wall of the projecting room have fixed frames 4 containing window frames 5, which have inclined edges. The upper edges are hinged and the lower edges are provided with knobs 9. The windows 5 close of their own weight and are recessed to allow slidable safety-shutters 10 to be mounted in guides on the face of the wall.
