According to David & John Erroll’s book, “American Genius, Nineteenth-Century Bank Locks and Time Locks,” The manufacturer Yale and Towne only built 13 of these locks, “Yale offered a Type DD and Type EE, combining two Ds or Es in concert. While none of these is known to survive, records show that Yale did sell three Type DDs in March 1890 and thirteen Type EEs between November 1889 and December 1891.” American Genius, page 246.
The Lock here offered is a model EE and has the serial number 13, see picture #16.
This 72 hour safe-time-lock is equipped with six American Waltham Watch Co. pocket watch movements size #14, model 84. The cluster on the right has the movements with the serial numbers 4’527’406, 4’527’408, and 4’527’409; the serial numbers on the movement-cluster on the left are, 4’527’318, 4’658’574, and 3’509’511. The movements in the cluster on the right seem to have the original movements with consecutive serial numbers, the cluster on the left seem to have some of the movements replaced. The damascening pattern to decorate the movements is called “Hillside.”
This time-lock is based on Emory Stockwell’s patent with number 363’920, issued on May 31, 1887, see picture #19-20.

History:
The “Great Burglary,” the robbery of the Northampton National Bank in Northampton, Massachusetts on January 26, 1876, did not start at the bank but shortly after midnight at the cashiers private residence. After being tortured and threatened to be killed by the seven burglars, he revealed the combination to the safe. The robbers stole $1,6 million in cash, bonds, and other securities. This robbery went down as the biggest in US history.
The banking industry was clear from this point on; the weakest link in the security system was no longer the locks, but the human element. Bankers would need a lock that could not just keep the robbers out, but the bankers themselves in order for them to be safe. The safe time lock was the answer. The safe time lock was already invented but not used as the needed clock works of the time were not very reliable. If the clock failed, the safe could not be opened the next morning. Redundancy was needed in case the clockwork failed. Only the most reliable movements were used in time locks. The time lock offered here is the only one of 13 ever sold which survived and the only one ever built with six movements. (April 29, 2023, Update: A second Sextuple safe time lock has been found as the author learned. This Yale type EE or Sextuple lock has the serial number 7.)
