He had to be on duty from 7 p.m. to 7 a.m. and give a signal every hour to prove that he did not sleep. The signal every hour to prove that he did not sleep. The signals were made with astonishing exactness. One night an inspector arrived and saw Edison sleeping in a chair. 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 instruments got busy and one lever threw open the key while the other sent the signal over the wire. The inspectors seized the sleeping boy, roused him and “fired” him. That is why the first of Edison’s numerous inventions was never patented.
