Inventor giving you a ring? (4)
I believe the answer is:
bell
I believe this is a double definition.
'inventor' is the first definition.
(Alexander Graham Bell)
'a ring?' is the second definition.
(both can mean to call on the phone)
'giving you' acts as a link.
(Other definitions for bell that I've seen before include "Alexander ..., inventor of the telephone" , "Scottish-born inventor of the telephone, d. 1922" , "Inventor - clanger" , "Stag's cry; ringer" , "The frigate Lutine's hangs in Lloyd's of London" .)
