Model Triple P, c. 1895. This lock used the largest movements made by Yale, the size 'M' movement. The 'P' designation is used for the three movement version of the lock that was employed with an external bolt motor. The four movement version was designated as Quadruple N. According to a Yale catalog from the late 1800's the Triple P was a special order item only. The release for that motor is located in the bulged area at the bottom of the lock (see second photo) as opposed to the Triple M which had the conventional bolt dog for manually operated vault door bolts. These were Yale's largest time locks for use with large safes equipped with automatic bolt motors. In nearly all respects it is identical in appearance to Yale's most popular time lock, the Triple L, which used the next smaller movement in size, the 'L' size to control smaller automatic bolt motors. Case #114, movements #1799, 1800, 2124. 7" x 6 1/4"h x 3 3/8"d. file 171

Below a Triple P mounted to a Diebold vault door on top of the bolt motor mechanism.
