November 27, 1926 MOVING PICTURE WORLD 243 Film Cleaning (Continued from preceding page) secure such a solution and are using it daily in our department with excellent results. At this stage we were able to enlist the co-operation of the manufacturer then making the best machine on the market. He agreed over an extended period to exploit certain of our ideas and make any changes necessary to carry them out. We are pleased to say that the expriments have resulted in a cleaning machine which really does the required work quickly and inexpensively. We find that our operators can clean twelve to fifteen reels an hour. As they come oft the machine, they are handed to the in WHY PAY MORE?

Dupe Negatives Of the finest quality, on special duping stock perfected by Eastman Kodak Co., solely for this purpose. Made by the firm which thoroughly understands its handling through experience gained in three years of continuous use in making millions of feet of the finest dupe negatives ever produced. Why risk printing from original negatives when Dupe Negatives of equal or better quality can be made so cheaply ?

The actual machine, is made by the Dworsky Film Machine Corporation, 520 West 48th St., New York City. The film is first passed through a bath of the wash solution, contained in a trough A, about eight inches being submerged at a time. Felt brushes submerged in the liquid brush both sides of the film. The film then travels up through a series of four rubber wipers at B suspended on a spring suspension at the same angle, which wipe the film very much in the manner that a window cleaning "squeegee" wipes the water from a freshly washed window pane. The film then passes between flannel strips fed from reels Rl and R2 and slowly driven in an opposite direction to that in which the film is traveling. The points of contact with these strips are arranged at offsetting points, so that the tension of the film is sufficient to polish it thoroughly on both sides. The film then passes through two rubber rollers at C, which simply pull the film through the machine. The film is then wound on a reel by an automatic take-up similar to the take-up on the lower magazine of a projection machine. The entire operation requires about 4J/' minutes to the thousand foot reel of film. The solution tank holds approximately one quart of the cleaning fluid, which is drained off into a filter after every seventh or eighth reel. After passing through the filter, the fluid can be used as often as it is thoroughly filtered and freed from the dirt that it carries after it has cleaned the seven or eight reels. By actual measurements, this filter from a day's work of one hundred reels of film has caught 14 cubic inches of dirt. I will repeat that the hopes of ultimately having available a satisfactory plant for clean ing film has been the goal toward which I have been striving for years. During these years of what you might classify as research there have been many machines considered and tested, many wash solutions analyzed, and every system with which we could come in contact investigated. Many of them have merit, and almost all of them offer in some manner a remedy for dirty film. In most instances, the plants that were investigated were operated by their owners as cleaning plants, and their business was confined to cleaning film and not to selling equipment for film cleaning. In such cases it meant the loss of time to transport film to and from our plant to theirs. This research work included a very careful study of various types of machines which were on the market and recommended for exchange use but which we found after a very careful analysis did not accomplish the result we desired. In analyzing a machine we found : First, in developing capacity, you must bear in mind the greater the speed of operation, the greater the possibilities of film damage. We have minimized damage by using large aluminum rollers with wide flanges to guide the film and by the elimination of sprockets. A gravity switch controls the motor so that, should the film break, the machine is stopped immediately. There are no buffs or fast rotating polishers to heat the film should it become stationary, and there are no sprocket teeth to injure it, or idler rollers to crease or mark it. We may safely claim that film which has received such treatment is so smoothly polished on either side that, besides being clean and transparent, it is able to pass through the projector v/ith the least possible friction.
