1921 - '''Harrington-Seaberg Machine & Electric Company''' was founded as a partnership by Fred Harrington and Severin Seaberg.

1922 - They received a contract for installing traffic signals in and around Chicago and another for Los Angeles.

1923 - They formed a corporation, '''the Harrington-Seaberg Fire Alarm Telegraph Co.'''. Later that year they changed the name once more to '''the Harrington Seaberg Corporation'''.

1925 - They take over the Magnetic Sign Flasher Company of Davenport

1926 - Axel Carlson listed as Vice President and Seaberg as president (what happened to Fred Harrington?)

1928 - They move to new building at 202 20th St. in Moline, IL, sales peak at $260,117.

1929 - Company sold to Gamewell Corp for $369,960 in shares and cash. (note the year - great move selling the company before the stock market crash, bad move accepting shares as partial payment?). Seaberg agreed to remain with the company as general manager. Shareholders at time of sale were:
- Severin Seaberg
- Carl Bergstedt
- Fred Harrington
- Carl Johnson
- George Strombeck
- James P. Pearson
- Carl Seaberg
- E.G. Swanson

The Gamewell Corp (of New York) was also the parent company for Eagle Signal Company.

1930 - Eagle Signals starts advertising that they are the exclusive distributor for Harrington-Seaberg signals.

As late as 1959 the Eagle Signal company resided at the old Harrington Seaberg building (202 20th St.).

As of 2002, there existed a Harrington Signal Company at 2519 4th Ave., Moline, IL - any relation?

== Controllers ==
Co-Ordiplex Traffic Control System
A name later adopted by Eagle for their line of controllers. Designed to have coordinated centralized control over the local controllers, hence the name, a master timer is in the main signal office or cabinet with local timers at each intersection connected via a 4-wire interface to the main timer to ensure they do not get out of synch. or quickly recorrect if they do.

Features of H-S controllers:
Sliding Scales or Percentages instead of Rigid Step adjustments
Speed or Time gradients clearly marked on the controller
Go indications are adjustable from 15% to 85%
Amber interval is, by default, 2 to 10 seconds
-Extended Amber available by special order
Ability to manually control intersections seperate of the system
Special control for Fire and Police emergencies

Installed in about 1925 in the Loop District of Chicago.

=== Induction Disc Drive Traffic Signal Controller ===
Can operate eight standard four-way signals equipped with 50W bulbs. Simply designed and uses no worm or belt-drive transmission.
