Eraser on a leash

(Popular Science, October '26)

At first glance a neat idea. On second thought perhaps, let it go and it could wind itself around the mechanism in all sorts of interesting ways :-)

Also shows that the archetype of the disk typewriter-eraser goes back some time.


  1. An eraser on a cord has all sorts of havoc-wreaking potential. How about a magnetic typewriter eraser? A 1955 Popular Science issue mentions the magnetic eraser idea. Apparently, it did not get much interest at the time.

    1. Oooh, magnetizing your mechanism - now what could possibly go wrong...

      Hmm, all these eraser-keepers look like they are solutions without a real problem needing solving. (And some added risk and costs.)
      Mr Williams in '55 clearly hadn't managed to sell his 1948 patent on a magnet-equiped eraser.
