Film Reels Refer to REELS Film Rewinders 'T' HIS device is used for rewinding films after they are run through the projectors, and are made in two general patterns, the bench and fire-proof enclosed type. The bench or open rewind is made in one piece types with the dummy and geared end complete in one unit, and others are made so that they can be clamped to a bench or shelf, while some are permanently fastened by means of bolts. Some are made with plain bearings and some have their spindles mounted on ball bearings. They range in price from $5.00 to $15.00. The enclosed rewinds are made in various patterns, both hand drive and motor drive models. The motor drive type is generally automatic in its operation, stopping at the end of the film or should the film break. Some are made with plain bearings and some have their spindles mounted on ball bearings. Some motor drive types also have multiple speed ranges and accommodate either one or two-thousands foot reels. One type recently brought on the market also has a detachable grinding and polishing attachment for aiding the operator in keeping his equipment in first class shape as well as keeping his arc lamp in good working order. The prices range from $50.00 to $160.00 complete. Atlas Metal Works, 2601 Alamo Street, Dallas, Tex. Automatic Film Rewinder. Harrisburg, Pa. BASS CAMERA COMPANY, 179 W. Madison Street, Chicago, 111.

International Fire Equipment Corporation, W. New Brighton, N. Y. Pyrene Manufacturing Company, 560 Belmont Avenue, Newark, N. J. Fire Prevention for Projectors TMPORTANT equipment has been developed which it is said definitely prevents a film fire in the projection machine. This equipment is a safety control device, that is easily installed and which is operated on the regular line voltage. The main control unit and dowser are mounted on the cone of the lamphouse and act as the main light cut off, taking the place of the regular dowser. The dowser is operated from five distinct points of contact, covering every avenue through which a fire could start in the projector while it is in operation or at a standstill with the film in it. All contact points are very sensative, and the dowser is instantaneous in its action, yet does not depend upon springs to actuate it. An arm with a loop and idler are so mounted as to engage with the upper film loop, another arm and idler is so mounted to engage the lower loop, an auxiliary idler is mounted so that it rides the film between the take-up sprocket and lower magazine valve rollers. These three points of contact with the film offer protection against fire from the following causes: film break at any point in the projector; loss of lower loop; loss of upper loop; mutilated perforations, i. e. : perforations in such condition that film will not ride properly through projector; failure of film to pass properly through projector from any cause; failure of film to take-up properly; bad reel in lower magazine; takeup belt breaking. Now there are other avenues by which a film fire can start, and the inventors of the device have apparently overlooked nothing in the way of safety. The entire projector is protected by a governor which is driven by one of the gears of the projector head, and this causes the dowser to actuate in case the following occurs; drive belts breaking;
