Really have to concur with you Phil, Big planers are poetry in motion, I really felt very sad when the biggest one left in the Clyde Area was scrapped about 18 years ago It was a real monster of a machine but as smooth and quite as a mouse after 65 years & still holding its accuracy
Thanks for sharing the video with us Ulma, could watch it all night!
Nothing like machinist porn. I've seen that one before, but it's still good. There are some videos of the old belt jumpers out there, those are neat to watch, too. I have two out in the shop, but one needs quite a bit of work, the other a motor drive (it came from a lineshaft shop). Really need to get it going.
What's a belt jumper?
Check this out, about halfway through it shows the belt drive, where the belt is moved back and forth from one pulley to the other to reverse the platen. This is an early one that uses one belt, with the reversing being done by gearing under the planer. The center pulley on this setup is an idler. Later ones did away with the gearing and used two belts, one twisted for reversing, and used two idlers on the outside with a drive pulley in the center. These had a small and large pulley on the lineshaft to give different speeds for cutting and returning. There was a variation of this where the lineshaft pulley was one size and the planer pulleys were two different sizes (they used 4 pulleys, two belts). These were also used on shapers with rack and pinion and screw drives.

This guy gives a good explanation of the two belt setup:
