Rattletop is a term used to describe a type of early 20th-century oil pump that was commonly used in the oil industry. It consists of a vertical beam connected to a central pivot, which is then operated by a pumping mechanism.

This pumping mechanism was widely used to extract crude oil from the ground before more advanced and efficient technologies were developed.
2. Rattletop as an adjective:

This term is particularly used when referring to shaky or unbalanced structures like a rickety table or a wobbly chair.
