Telegraph Machine
Backed by Law's Gold
Indicator Company and Western Union Edison opened a shop in Jersey
City. Edison worked on many forms of advancement for telegraphy. Edison
realized the true power of the companies backing him when Western Union
just bought out a competitor who was out selling them for a variation
of the printing telegraph. By the summer of 1870 Edison had taken out
seven patents relative to telegraphic communication. Then Edison was
asked to join the technical staff and improve on Callahan's stock
printer. Of course, Edison agreed. Weeks later Edison demonstrated a
device to the bored of directors, a new ticker which worked far better.
Edison was paid $40,000 for the invention.
On his own, in 1871 Edison started full scale production of stock
tickers. He even employed 150 men to make a large order recieved from
Western Union. Then He opened a small third party factory with George
Harrington, making the Edison & Harrison firm. This new partnership
aid at manufacturing automatic printing telegraphs. Some of Edison's
current side tracks include perfecting the phonograph and improving the
telephone.
