Sargent & Greenleaf, Rochester, New York - 3 movements, Model Triple D
Sargent & Greenleaf introduced their Model A, B, and C, in 1889. In 1896 S&G introduced the Model D, a smaller version but still using the same "L"-sized movements to fill a need for a more compact design fitting into smaller safe doors.
The snubber lever works and drop bolt are particularly nicely engraved in the early run of this model.
In this example the case remains the same jeweled bronze finish, but all of the snubber bar and drop bolt assemblies have lost their decoration.
By the 1920's Art Deco became popular and found its way into safe and vault design resulting in a sleek satin case, snubber and bolt drop assembly finish.
A. Model Triple D, later 6303, c. 1896. This is a smaller version of the Triple B. It's dimensions being 6.5" x 5" x 2.75" compared to the model Triple B size of 7.75" x 5.75" x 3.5". This example very early in the production run. All of the snubber components and drop bolt are fully decorated. All snubber bar parts including the four bolts that secure the assembly are stamped #11, the back of the case and door lock are also stamped #11, but the front lip of the case and bolt are #124, movements #2378, #2379, #2380. file 274
B. Model Triple D, later 6303, c. 1910. This is a smaller version of the Triple B. It's dimensions being 6.5" x 5" x 2.75" compared to the model Triple B size of 7.75" x 5.75" x 3.5". S&G was still using the gold jeweled case but by this time all of the snubber bar and drop bolt decoration had ceased. Case and bolt #D-610, movements #6257, #7418, #9180. file 135
C. Model Triple D, later 6303, c. 1920's. Same as above, but in later version of silver satin finished case. By this time the jeweled bronze case became an option with the satin case finish now more in keeping with contemporary "Art Deco" designs emerging on safe and vault door designs. The two comparison photos show it against the lock Model Triple B. It still used the same sized movements as the larger model, the "L" sized movement, but with a more compact bolt dog configuration. Case and bolt #908, movements #7848, #2010, #6940. file 117
