He was about to shake him when he caught sight of a mechanism on a table near the telegraph instrument. He waited to see what would happen. When the hand of the clock pointed to the hour, the instrument got busy and one lever threw open the key while the other sent the signal over the wire.
The inspector seized the sleeping boy, roused him and “fired” him. That is why the first of Edison’s numerous inventions was never patented.
