Illustrates a method of controlling a number of clocks which was patented by J. A. Lund in 1876 and used on the Victorian railways in 1892. In this method the hands of the ordinary mechanical clock are corrected every hour by a signal transmitted form a master clock.

[edit] How it works

The device for correcting the hands is mounted at the top of and in front of the dial; it consists of two pivoted arms attached to the armature of an electro-magnet. Exactly at the hour the signal arrives from the master clock, the armature is pulled down, and the two arms close together, scissors-like, grasping the minute-hand and forcing it to the central position.
