The company was founded in 1845, in Paterson, New Jersey, by a partnership between William Swinburne and Samuel Smith.
Swinburne had been a pattern maker for Rogers, Ketchum and Grosvenor of Paterson, who worked his way up to become shop foreman.
Afterwards, the firm reorganized, with James Jackson joining the partnership, and became the New Jersey Locomotive and Machine Company.

It was delivered to a predecessor of the Great Northern Railway in 1861, and is the sole surviving engine built by the firm.
