Two views of "circulating swings" with patients strapped in; bottom view shows a man on a platform rotating a swing on which a man is strapped. Illustration appeared in Practical observations on the causes and cure of insanity, 1818. William Saunders Hallaran, Doctor, described the use of the swing in the Lunatic Asylum of Cork, England as "a safe and very effectual remedy for the description of maniacs". He fully credits Joseph Mason Cox, 1811 AD with the invention which induced the vomiting without (emetics). The circulating swing erected in his asylum was worked by a windlass, and was capable of being revolved a hundred times in a minute. "This method of subduing furious maniacs, has succeeded in an admirable manner". Hallaran was the primary doctor for a major asylum and testified boldly that the swing cured the insane. "The advantages to be derived from the swing, in the intermitting form of insanity, cannot be too highly estimated. Several proofs of its superior efficacy have come within my observation, where, immediately on the approach of the paroxysm, the symptoms had nearly subsided on the first effort." The key was to bring those who are out of control, into submission.
