Supreme Mechanical Order of the Sun

The Supreme Mechanical Order of the Sun was a fraternal society for mechanics and allied trades, founded by members of the New York Workingmen's Union in late 1866 or 1867.

Structure
Each local lodge was called a League of Friendship, which existed under a State Council, these in turn under a National Council.

Ritual
McNeill's The Labor Movement (1887) describes the Supreme Mechanical Order of the Sun as having an extensive ritual with numerous degrees; press coverage of the order specified three primary degrees, and three or four more at the level of the State Council. According to Upchurch, as published in The Life, Labors and Travels of Father J. J. Upchurch (1887), one of the post-initiation degrees was called the "Knight of the Iron Ring."

Secessions
Members of the order in Meadsville, Pennsylvania joined John Jordan Upchurch in the founding of the Ancient Order of United Workmen (AOUW) in October 1868, splitting from the parent order.
