Animated device used on King Edward perhaps (7)
I believe the answer is:
chipper
This clue is a double definition.
'animated' is the first definition.
(thesaurus)
'device used on king edward perhaps' is the second definition.
(a chipper might be used on a King Edward potato)
(Other definitions for chipper that I've seen before include "Cheerful - machine used on timber" , "employee in fast-food joint" , "Debonair" , "full of beans" , "Smartly-dressed" .)
