Hooke joints, more commonly known over here as universal joints, were first investigated systematically by Robert Hooke beginning in 1667, and given the name "universal joint" by him in a treatise he published in 1676. That far back! It's also known as a U-joint, Cardan joint or Spicer joint. The Wikipedia entry is quite fascinating, albeit (at least to me) equally abstruse.

A visitor sent me a photo of this lovely wooden-cased record player made by Northern Pacific. The company may have been out of North Vancouver. Can anyone shed any light on this firm?
