CLOCK No. 16


ELECTRICAL CLOCKS - IMPULSE TYPE
Clock No. 16

The difference between this Master clock and the Clock No. 12 is that it has a pendulum of a length to give half second beats and contacts for providing half-minute pulses only in the secondary circuits.  It is however, provided with a time piece dial, the movement of which is similar to that of the other secondary electrical dials.

This clock is intended for use in sorting offices and on smaller installations where there is no need for the seconds impulse.

The details of the pendulum maintaining mechanism and synchronizer are similar to those of Clock No. 12.

Superseded by Clock No. 36.
