Sargent & Greenleaf, Rochester, New York - 2 movements

In 1874 S&G introduced their Model #2 time lock. This was their first time lock-only model that operated directly on the bolt work of the safe. Their Model 1 operated by disabling the safe's combination lock.

Below is very early and rare example of an S&G model #2 time lock, 1876. Any time lock made before 1880 is quite rare. This lock is nearly identical to the original time lock invented by James Sargent and first put on a vault door in 1874. Only a few of the first production run of this lock had the black enamel dials. The Model 2 had many changes over the years of it's production from 1874 through 1927. Erroll's book divides these changes into 15 styles through this period. This example is the fourth type of Model 2 or #2[4]. Although made for just over one year it was the first time lock to get a large production run, thought to be between 150 to 200. One of three known completely intact examples. Formerly from the Harry Miller collection. Another example is in the John M. Mossman collection in the Museum of The General Society of Mechanics and Tradesmen, New York, NY. Case #531, movement #535. file 101

Compare this example to the other S&G model #2 locks on the next page. Also compare to a similar rare vintage model #3 with the same dial and case features.
