A piece of furniture that shames you about time, loudly, every hour.

means A tall freestanding pendulum clock, housed in a wooden case, that ticks, chimes, and marks the hours in your hallway with great ceremony.

from The clocks themselves date to the late 1600s, invented after the anchor escapement made long pendulums (and hence tall cases) practical — the earlier name was simply 'longcase clock' or 'tall-case clock.' The name 'grandfather clock' arrived later, and the popular story is a good one: it comes from the 1876 American song 'My Grandfather's Clock' by Henry Clay Work, about a clock that lived exactly as long as its owner, stopping forever the moment he died. The song was a massive hit, and the nickname simply stuck to the furniture — a rare case where a pop song renamed an object.
