 "36. Mangle-wheel and pinion -- so called from their application to mangles -- converts continous rotary motion of pinion into reciprocating rotary motion of wheel." Found in Five hundred and seven mechanical movements. I wonder what proportion of technical people in the past were expected to know this stuff cold compared with those today? Then again, they didn't know about mathematical programming either.
