Although there are lots of possibilities of answers like kerosene lamp, kaleidoscope but I wanted to choose word "knocker-upper."

"Knocker-upper" ( profession) is a compound noun that refers to a person who used to go around neighborhoods in the early morning, tapping on windows with a long stick or rod to wake people up. The profession was prevalent in the 19th and early 20th centuries before alarm clocks became widely available. The word "knocker-upper" is a combination of "knocker" (meaning someone or something that knocks) and "upper" (referring to the early morning, as in "up and at 'em").It is no longer seen in cobbled streets because the profession became obsolete with the widespread availability of alarm clocks.

Thankyou for your clues' K' @patjewell
