Model - Type 3, c. 1910. The Type 3 was designed to operate directly on the safe bolt works rather than with a a bolt motor as in the type 1. This lock is equipped with a rare long duration option of 120 hours rather than the standard 72 hours seen on all other versions. During this time some other manufacturers offered their time locks in an optional longer duration. Other examples are from Mosler and Yale. But it was expensive and moreover very few banks saw the need for these since 120 hours covers five full days. Only the largest vault doors would have used a four movement lock and these would nearly all be commercial banks rather than a private entity. This version was mounted to vault doors that used standard bolt work as illustrated below. That bolt work would have entered the case from the lower right hand side as seen in the fourth photo. Plain brass case with original acid-etched and beveled door glass. This is the only example of a long duration quad movement known to the author. Case #9043. 7"w x 4.25"h x 2.5"d. file 205
The photo below shows a Diebold round door with a four movement Diebold Type 1 time lock but used in an application that dogs the bolt work and the door using manually operated bolt actuation. This is a curious color combination since a brass colored Diebold lock would have been more in keeping with the design of the rest of the door. But this was obviously deliberate since the rest of the hardware is also silver colored.
