Description:Excerpt from Journal of the Society of Motion Picture and Television Engineers, Vol. 57: This Issue in Two Parts; Part I, December 1951 Journal; Part II, Index to Vol; 57; July-December 1951 The design and proving of the light, fast-moving parts in business machine mechanisms has been a difficult and time-consuming job. Advances in this field, while continuous, have been obtained only at a high cost in time and labor. In our study of the action of these mechanisms, we had been limited to the current instrumentation methods and to others which we improvised to record time and movement. But we had felt for some time that if we could slow down or actually stop the normal, rapid motion of parts under study, then our engineering work would be greatly simplified. Five years ago our Engineering Group had a particularly perplexing problem which had been under study for several years and to which a number of solutions were submitted. The question was how could we choose the right one without extensive testing. A high-speed camera capable of exposing 3000 frames a second was procured and put to work on this problem. The camera quickly proved to the satisfaction of engineering the correct solution. An entirely new tool had been added to our engineering analysis. However, it was a problem to sell this method to all of our development groups. Today, our high-speed camera is very much in demand and our camera work has developed to the point where we take pictures in the morning and have them ready for analysis the afternoon of the same day. The high-speed camera like any other analyzing equipment can be used only to study or determine trouble if you know where to look for it. The mere shooting of pictures generally results in only exposing film of no value. If a machine is missing operations, you will have only approximately one second to film that operation and may have to shoot more than one roll of film to pick it up. Adding machine operations are rather complex. Let us briefly outline one of our typical operations so that our application of high-speed photography can be more readily understood. In the hammer section of an accounting machine, spring-energized hammers are used for printing on rubber platens or printer rolls.
