April 16, 1927 EXHIBITORS HERALD 47 Why do you book the best pictures available? New Control Device Offers Protection Against Film Fire The fact that most projection room fires are film fires which start in the projector during exhibition of the picture makes it highly important that some method be employed to prevent these fires, which always result in a property loss and at times the loss of human life. The Sentry Fire Control is a new device for preventing film fires in projectors. It appears adequately to fulfill all claims made for its efficient operation. It is simple in construction, positive in its action, easy to install and does not interfere with operation of the projector. The Sentry Control is operated on low voltage through a small step-down transformer. A dowser is mounted on the cone of the lamp house and acts as the main light cut-off, taking the place of the regular dowser. The “Sentry” 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 with film in it. All contact points are very sensitive, and the dowser is instantaneous in its action. A pivoted apron is mounted so that it comes in contact with the upper film loop. An auxiliary idler is mounted so that it rides the film between the take-up sprocket and lower magazine fire valve rollers. These two points of contact with the film offer protection against fire from the following causes ; A. — 'Film break at any point in projector; B. — ^Loss of lower loop; C. — Mutilated perforations, i. e., perforations in such condition that film will not ride properly through projector; D.— Failure of film to pass properly through projector from any cause ; E. — Bad reel in lower magazine ; F. — Failure of film to take up properly from any cause. Now there are other avenues by which a film fire can start, and the young men who are responsible for the Sentry device have apparently overlooked nothing. Idlers mounted on arms ride the motor drive belt and take-up belt. Failure of either belt (such as jumping or breaking) causes contact through mercury switches instantly operating the dowser. Failure of current supply to motor results in instant actuation of the dowser. This winter has seen a number of Film Fire prevention devices demonstrated, but most of them only protected at one point and some of them not at all. I have seen several demonstrations of the Sentry device and it always functioned perfectly. I understand that the device has been approved by Underwriters Laboratories and has the endorsement of several insurance companies and fire marshals. EARL J. DENISON.
