Abstract

198,815. Dickinson, F. W. March 17, 1922. Kinematograph picture films.-A film for projection is formed with a central rank of pictures a of standard area and with narrower side ranks of records b separated from the central rank by spaces c in which two or more lineal rows of perforations are provided. One row of perforations d serves for driving the film, and the other perforations f, which may be of any desired shape, serve to facilitate flexing of the film in the gate of the projector. The records b may be pictures or descriptive matter such as sub-titles or dialogue. Additional driving perforations may be provided along the margins at the outer edges c<1>.
