A. c. 1920's. A rare dual purpose time lock. Less than fifty were made with this being the only known example. This timer contains two conventional Seth Thomas 72 hour Type T movements and one modified Type T movement that has a 7 hour duration. Type T movements were the smallest coffin style movements made for Yale. A day/night switch is provided to engage the 7 hour movement during the day time hours. This lock would fulfill two functions. The first to act as a normal overnight/weekend time lock and the second to secure the vault for short period of times during the day. the 7 hour timer could be set for intervals as short as 15 minutes. Case #242. The first two movements consecutively numbered T2494, T2495, special timer movement T2445. To see another Yale with modified Type T movements click here.
