To understand the manual, one must first understand the machine. Unlike a standard time clock that stamps start and end times, the Calculagraph was a duration computer . It measured the elapsed time between two events, typically the start and finish of a manufacturing operation. The Cal-6B, a robust electromechanical model, allowed a worker or supervisor to press a lever, which would stop a precisely governed escapement mechanism and print the calculated time (e.g., “0H 14M”) directly onto a job card. The manual’s opening pages do not boast of features; instead, they state a problem: How to eliminate the subtraction errors and wasted clerical time inherent in manual time-sheet calculations. The solution, as the manual meticulously outlines, is the Cal-6B. Symptom: The timer runs slow
