F. H. Richardson's bluebook of projection (1935)

THE FILM 185 equipped with a water pan or tank capable of holding not less than thirty-six square inches of water surface for each reel it is designed to hold. The tank should be connected with the water supply and controlled by an automatic valve that will maintain the water level, feed ing water automatically to the tank when the water surface drops down to a fixed, pre-determined point. Each tank should he supplied with an overflow, so that under no condition will the water ever reach the film. 1 [andling the Film (45) The audience should be the first consideration of the projectionist. Its ultimate safety is the thought uppermost in his mind every minute of the working day. Consequently when film shipments arrive his duty is to make a careful check to discover any likely faults such as loose splices, ripped sprocket holes, etc. ; if the film is dirty or streaked with oil it should be cleaned before being put into the projector so as to give patrons pleasing performances as well as safe ones. (46) If repairs have to be made on prints that have arrived from the exchange ostensibly in good condition, their character and location should be noted and a memorandum sent down to the theatre manager giving the time devoted to making the repairs. A copy of this memorandum should be sent to the exchange manager and if the repairs have been extensive and considerable time devoted to making them, a bill to the exchange would not be out of order. (47) Whenever an exchange fails to heed the complaint of the theatres and continues to ship out film without the proper inspection and repairs, the matter should be brought to the attention of other agencies which will compel the exchange to handle its film properly: to the local projection union, to the local theatre managers' organization, to local municipal authorities and to the home office headquarters of the film company.
