. Scientific American Volume 24 Number 05 (January 1871) . nted by Cornelius Dreble, forKing James—the magnetical globe of Terella, suggestedby Pet. Peregrinus, with the wheel that he, Taisner, and Car-dan thought might be kept in motion by pieces of steel andloadstones—are, like i he Bishops own wheel and plummets, and his application of Archimedes screw, inadequate to thegrand end for which they were designed. Without enlarging on this head, we shall proceed withthe description of a machine which, were it possible to makeits parts hold together unimpaired by rotation or the ravagesof time, and to give it a path encircling the earth, would as-suredly continue to roll along in one undeviating course tilltime shall be no more. A series of inclined planes is to be erected in such amanner that a cone will ascend one (its sides forming an acuteangle), and, being raised to the summit, descend on the next(having parallel sides), at the foot of which it must rise on athird and fall on a fourth, and so continue to do alternatelythroughout. Fig. 20. -■Hi The diagram -is the section of a carriage, with broad, coni-cal wheels, resting on the inclined plane. The entrance tothe carriage is from above, and there are ample accommoda-tions for goods and passengers. The most singular propertyof this contrivance is, that its speed increases the more it isladen; and when checked on any part of the road, it will, when the cause of stoppage is removed, proceed on its jour-ney by mere power of gravity. Its path may be a circularroad formed of the inclined planes. But, to avoid a cir-cuitous route, a double road ought to be made. The car-riage not having a retrograde motion on the inclined planes, a road to set out upon, and another to return by, are indis-pensable. I am indebted to a much-respected friend for the hint ofthis means of effecting a veritable pcrpeual motion. The Perpetual Motion Hunter is the title of an articlein the Imperial Magazine, vol. 6, 1824: Fig. 21.scientific-am
