A Brief History of S&GThe Sargent & Greenleaf Story—Over a Century of SecuritySargent & Greenleaf prides itself on a tradition of quality and innovation which stretches back to 1857. It was thenthat James Sargent, a bright and inventive young sales agent for Yale & Greenleaf Lock Manufacturers, made thedecision to build a lock that would offer security far surpassing that of any device available of the time. The resultof his resolve and genius was Sargent’s Magnetic Bank Lock, the first successful key changeable combination lock. The lock gainedalmost immediate acceptance from safe manufacturers and the United States Treasury Department, bringing financial stability andpaving the way for James Sargent to continue bringing new ideas and products to the security industry.In 1865, one of Mr. Sargent’s former employers, Halbert Greenleaf, became his equal partner in the firm of Sargent &Greenleaf. A manufacturing facility was built in Rochester, New York, and the company remained in that city until 1975. James Sargentwas never one to rest on the success of past achievements. In 1868, he invented Sargent’s Automatic Lock, bringing refinements to theoriginal Sargent’s Magnetic Bank Lock.Then, in 1873, using parts from locks and a pair of eight-day kitchen clocks, Mr. Sargent created the first time lock to beinstalled 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.In 1880, Mr. Sargent connected one of his combination locks to a delay timer, creating the first Time Combination Lock, alock that would remain locked for a predetermined amount of time after the combination was dialed. This was the forerunner of today’sSargent & Greenleaf Timebination.These inventions are just a sampling of the numerous advancements and innovations in security hardware that can beattributed directly to James Sargent.
