An Electric Clock Running Since 1870

An electric clock, made by Daniel Drawbaugh, a pioneer electrical inventor, which is now running at Carlisle, Pa., has continued to operate since 1870 without winding. The pendulum, weighing forty-five pounds, is operated by an ordinary electromagnet and a permanent magnet armature, the current in the electromagnet being reversed as it passes the armature. It is expected to run one hundred years before needing renewal of any parts.
