The Optical Lantern and Cinematograph Journal (Nov 1904-Oct 1905)

252 THE OPTICAL LANTERN AND CINEMATOGRAPH JOURNAL. ALTERNATIVE METHODS OF PREVENTION. Other methods of preventing names at the projection aperture from reaching the reels of film have been proposed, such as a non-inflammable plate of considerable size arranged above the projection aperture, and extending rearward and to the sides for a considerable distance. Such a plate will sometimes prevent a flame at the projection aperture from reaching the film on the supply reel ; but it is by no means as certain in its action as the magazines already mentioned, for the film above the plate is fully exposed, and if the flame rises above the edge of the plate it may strike the exposed film and set fire to the entire reel. Another device which has been proposed to prevent the transmission of a flame from the projection aperture to the film reels consists of a pair of flat tubes or guides extending above and below the projection aperture, and made of noninflammable material, the idea being that, in the small space afforded by these guides for the passage of the film, a flame will be extinguished. As a rule, this device operates successfully ; but as the reels themselves are exposed, a flame flaring up suddenly at the projection aperture may reach one of the film reels in spite of the guides. ENGLISH V. AMERICAN METHODS. A plan of preventing fires from the use of moving picture apparatus that has been adopted in England to a considerable extent is to inclose the entire apparatus in a fireproof box large enough to contain the operator also, and to lock the operator in during the exhibition. This plan has the merit of making operators careful ; but many grounds of objection to it are obvious, and American operators of moving picture apparatus are unwilling to be locked in such a box while giving an exhibition. Considered from all points of view, the most satisfactory and thoroughly reliable means for rendering moving picture apparatus safe is a fireproof magazine for the film supply reel, and a similar magazine for the take-up reel. Such magazines answer all the requirements and have the advantage of being readily portable, and of being easy to apply to any standard moving picture machine. Baxter Morton. We haue others!
