The first time lock for bank vaults

Sargent & Greenleaf prides itself on a tradition of quality and innovation which stretches back to 1857. It was in 1873, using parts from locks and two kitchen clocks, James Sargent created the first time lock to be installed on a bank vault door.

He personally connected the time lock to the vault door of the First National Bank in Morrison, Illinois, on May 26, 1874. This lock continued to secure the vault for nearly forty years until the bank was remodeled and a larger vault was built.

James Sargents’ tireless efforts and clear vision of what makes for good security were responsible for the success of his young company. These same qualities continue to drive Sargent & Greenleaf today.
