Yale & Towne Manufacturing Co., Stamford, Connecticut - 3 movements, Type T-361

The T361, left was the antecedent to the Y361, right.

Model T-361, c. 1907. Sometime in 1906 the Consolidated Time Lock Company ceased production. Consolidated was the supplier of time locks for Ely Norris Safe Company's cannonball-style safe. Norris turned to Yale for a replacement. Yale's interim design for Norris was the T-Movement Automatic; a few were made in 1907, until  the T-361 lock was introduced as a replacement, and was itself a temporary model until the introduction of the Y-361 introduced in 1908.¹ The Model T361 contained three of Yale's smallest size 'T' movements and a key wound automatic bolt motor which would withdraw the safe door bolts when the timers would permit. Why did Yale choose to design a completely new movement and bolt dog mechanism in the Y-361 just a year or so later? It would seem logical and expedient for Yale to use an existing movement in current production, the T style rather than go to something entirely new. Perhaps this first design was not satisfactory, requiring the redesign. As a result very few of this type were made with only six known to survive. The last two photos show this lock next to its successor, the Y-361. 6 1/8" dia. x 3"d. Case #60, movement #T1510, T1511, T1512. file 151
