Not the best patent to use if you want to settle the debate. This one from Wheeler is the nail in the coffin: patent
It also shows why it was over and not under as at the time, the TP holder was a hanging wire, which kept the paper against the wall. Not protruding out like todays hangers.
Not that the over/under debate was even a thing, but this should convince those diehard lunatics not to hang their TP improperly!
