Derrick

The name of the finisher of the law, or hangman about the year 1608.--'For he rides his circuit with the Devil, and Derrick must be his host, and Tiburne the inne at which he will lighte.' Vide Bellman of London, in art. PRIGGIN LAW.--'At the gallows, where I leave them, as to the haven at which they must all cast anchor, if Derrick's cables do but hold.' Ibid.

an apparatus for raising sunken ships, &c. The term is curiously derived from a hangman of that name frequently mentioned in Old Plays, as in the Bellman of London, 1616.

“He rides circuit with the devil, and derrick  must be his host, and Tyborne the inn at which he will light.”

The term is now almost general for all cranes used in loading ships, or doing similar work of a heavy nature.
