- John D. Boyle (1891-1968), an English-born New York advertising executive who lived in Greenwich, Connecticut, patented several mechanical puzzles.. At least two of these were produced, including this one, which sold under the name TRI'-N'-DO-IT. The puzzle consists of three wooden cylinders held together by three wooden dowels and a shaped metal piece. The goal of the puzzle is to take apart the pieces.
- A mark on one of the cylinders reads: TRI'-N'-DO-IT (/) TR.MK. (/) US PAT 2207778 (/) IT COMES APART (/) WITHOUT FORCE. Boyle applied for a patent for this puzzle August 30, 1939, and received it July 16, 1940.
