It's a carrier, a hod, a scuttle, a pail. Whatever it's called, it's a convenient item used to carry coal to a fireplace or stove. The word "hod" seems to be preferred in England. The term "scuttle" or "carrier" is used in the United States.
Coal was used in fireplaces and stoves to provide heat. Some coal carriers were simple metal pails; others looked like pieces of furniture. It also was used to carry ashes away from a fireplace or stove.
The device at Smith’s Tavern has a long metal handle attached to a “U” shaped bucket. The lid of the bucket can be opened and closed with a twisted wire pull.
