Well, maybe one particular design, but I've seen cars from the 1920's or earlier, which had a CVT. The shifting was done by a tillar - move it one way, the "gearing" was highest, move it to the middle, it's in neutral, move it the other way, you're in reverse. It uses a spinning disk, more or less a flywheel, on the engine side of it, and then the tillar moves an idler from one side of it, or to the middle, or to the other side. Speed changes by the ratio of the effective radius of the flywheel (how far from the center the of it the idler is), and in the middle the idler doesn't move at all. I don't know the name of this type of transmission, but it's definately continuously variable, and transmits power, and predates the 1950's by several to many decades. I don't recall what model of car I saw it on, though. This isn't to be confused, of course, with the belt-pulley-cone type CVT which may be the variety you're mentioning. Dave Hinz
