Inventor's clangers (5)
I believe the answer is:
bells
'inventor's clangers' is the definition.
'bells' can be an answer for 'clangers' (things which make clanging noises). I'm not sure about the 'inventor's' bit.
'inventor's clangers' is the wordplay.
'inventor' becomes 'bell' (I've seen this before).
'clangers' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'bell'+'s'='BELLS'
Can you help me to learn more?
(Other definitions for bells that I've seen before include "Chimes" , "Scotch?" , "Those ringing in the New Year" , "Ringing objects" , "Ringing instruments" .)
