midpoint between input and output shafts. Often springs are used to reduce the backlash mechanism. the advantage of this type of connection, compared to the two universal joints, is its compactness. adapter named for John Oldham who invented it in Ireland, in 1820, to solve the problem with the placement of the paddle in the design catalog wheel steamer.
