This device at Smith’s Tavern is a wooden barrel pump. It was a “T” shaped plunger handle and a long circular shaft with a hole near the top were a bung or spigot would be inserted (which is missing from the device at Smith’s Tavern).
A barrel pump was used to draw liquid from a wooden barrel or keg to be dispensed into another (most likely smaller) container. The liquid in the barrel was commonly vinegar, cider or whiskey.
