Cathy Comb Home

 I've just found this design I must have drawn when I was 16

I had a girlfriend at the time called Catherine with very long hair.  In fact it was so long she could sit on it.  Anyway, I was amazed at how much time she spent combing - about half an hour every day.  She'd start at the bottom and work her way up, combing all the way to the ends with each stroke.

I thought that there had to be a better way, so I came up with this machine.  The two belts rotate in opposite directions and the angle between them gradually decreases so that it starts off just untangling the ends and ends up combing the whole length of the hair.

Fortunately it never got built.
