Tesla Electric Light & Manufacturing
Nikola Tesla formed the Tesla Electric Light & Manufacturing company in April 1887. Based in Irving street, Rahway, New Jersey, the company started after Tesla left Thomas Edison's employment following a disagreement over payment. Tesla planned to sell and license his patent and innovations. Tesla invented an arc lamp of high efficiency; electromagnets or solenoids and a clutch mechanism controlled the carbon electrodes and it had an automatic fail-switch. The company earned money, but most of the capital gained went to the investors. Ultimately, financial investors disagreed with Tesla on his plan for an alternating current motor and eventually[when?] relieved him of his duties at the company.
Tesla had already been issued the following patents:
- U.S. Patent 334,823 - Commutator for Dynamo Electric Machines - 1886 January 26 - Elements to prevent sparking on dynamo-electric machines; Drum-style with brushes.
- U.S. Patent 350,954 - Regulator for Dynamo Electric Machines - 1886 October 19 - Automatic regulation of energy levels; Mechanical device to shift brushes.
In 1887, after Tesla had founded his company, the US Patent Office issued the following patents to him:
- U.S. Patent 335,786 - Electric arc lamp - 1886 February 9 - Arc lamp with carbon electrodes controlled by electromagnets or solenoids and a clutch mechanism; Corrects earlier design flaws common to the industry.
- U.S. Patent 335,787 - Electric arc lamp - 1886 February 9 - Arc lamp's automatic fail switch when arc possesses abnormal behavior; Automatic reactivation.
- U.S. Patent 336,961 - Regulator for dynamo electric machines - 1886 March 2 - Two main brushes connected to helices coil ends; Intermediate point branch shunt connection for third brush.
- U.S. Patent 336,962 - Regulator for Dynamo Electric Machines - 1886 March 2 - Auxiliary brush[es] shunting a portion or whole of the field helices coil; Regulates energy flow; Adjustable level of current.
