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

The illustrations above are the original patent issued June 20, 1911 to W. H Taylor, an employee of Yale for the Y-361.

Model Y-361, c. 1915. The Y-361 was the successor design to the T-361 which in turn succeeded the T-Movement Automatic used in Ely Norris Cannonball safes (so named because of their overall ball-like shape). Uses consecutively numbered Seth Thomas pie shaped Type Y movements. These movements were unique to this style of time lock which, in turn, was unique to this style of safe making this time lock quite collectible. The lock contained a key wound bolt motor which would withdraw the safe door bolts when the timers would permit. In the picture one can see all the associated hardware that was connected to the lock - combination lock, slides, door bolts. A sister lock to this one, a two movement version, was concurrently produced and designated the Y-261. It has very limited success and only one example is known to have survived.

Last picture shows roughly how the components were positioned. Of the three thousand time locks produced about three hundred survive. The photos below show the actual safe from which this lock was removed. Cannonball type safes were one of the most popular models made and many time lock companies made locks that could work in this type of safe such as Diebold, Banker's Dustproof, as well as Yale's LS31 and Triple L . 6 1/8" dia. x 3"d.
