IBM and its predecessor companies made clocks and other time recording products for 60 years. Beginning with the 1911 formation of the Computing-Tabulating-Recording Company and culminating in the 1958 sale of the IBM Time Equipment Division to Simplex Time Recorder Company, IBM manufactured and sold such equipment as dial recorders, job recorders, recording door locks, time stamps and traffic recorders. This device, which resembles a wider version of the classic IBM Type A Time Stamp, was used for recording and stamping the time on mail, documents or job tickets. |
