Abstract
Flash fire-valves are designed to eliminate all danger of serious film fires in projectors during projection caused by broken or tom sprocket-holes, bad patches, worn out mechanism, etc. The operation of the valves makes it impossible for fire in the projector during the process of projection to get into either film magazine, and limits the length of film that can burn in the projector to about 18 inches, or just what is threaded through the mechanism.
