His examination is like that made by the rack and the wheel. Addison.
This mode of torture is said to have been first employed in Germany, in the fourteenth century. The criminal was laid on a cart-wheel with his legs and arms extended, and his limbs in that posture were fractured with an iron bar. In France, where its use was restricted to the most atrocious crimes, the criminal was first laid on a frame of wood in the form of a St. Andrew's cross, with grooves cut transversely in it above and below the knees and elbows, and the executioner struck eight blows with an iron bar, so as to break the limbs in those places, sometimes finishing by two or three blows on the chest or stomach, which usually put an end to the life of the criminal, and were hence called coups-de-grace—blows of mercy. The criminal was then unbound, and laid on a small wheel, with his face upward, and his arms and legs doubled under him, there to expire, if he had survived the previous treatment. Brande.
(c.) (Naut.) A circular frame having handles on the periphery, and an axle on which are wound the tiller-ropes, which connect with the rudder for steering a ship. (d.) (Pottery.)

(e.) (Pyrotechn.) A fire-work which revolves, while burning, on an axis, by the re-action of the escaping gases. (f.) (Poet.) The burden or refrain of a song.
“This meaning has a low degree of authority, but is supposed from the context in the few cases where the word is found.” Nares.
