Liberty Ignition Company

The Liberty Ignition Company incorporated on May 3, 1919 with 7500 shares and a capitalization of $100,000.

A large brass base plug with a nickel alloy electrode angled to repel oil and a steatite ceramic insulator that has great strength and low thermal expansion. It is unclear if two varieties exist. Their advertisements claim to use steatite stone as well as a steatite ceramic that is fired from clay and probably made by the Federal Corporation. The unique shape makes it a desirable collectable.

The “Liberty” name is also associated with Mosler, Casey-Hudson, and the Liberty Spark Plug Company.

Patent number 1,347,874 was issued to James E. Rich. Filed March 5, 1919 and issued July 27, 1920.
