"References to the drawings of the machine hereunto annexed:--Fig. 1 is the section of the machine. A, A, B, a cranked or double center, fixed to the stand or frame D by the bolts E. C, C, the wheel which turns or revolves round that part of the cranked center mark A. F, levers which turn or revolve round the cranked center B. G, G, rollers or weights which revolve in the circular guides or grooves by means of the leavers F. H, H, circular grooves or guides which are affixed to the inner sides of the wheel. N. B.--the distance from A to B is the radius in all cases to determine the space between the center of the guide or groove H and the center of the roller or weight G. The distance of the two concentric circles which form the guides or grooves H must be equal to the diameter of the roller or weight G. I, I, springs which stop the rollers or weights G from returning when at the horizontal diameter of the wheel. K, weights, which may be increased or diminished at pleasure. L, ledges which connect the sides of the wheel together. N. B.--By fixing cogs or teeth on the rim of the wheel, so as to connect it with any mill, machine, or engine to which motion can be given by a wheel, the power of this machine may be communicated." Explanation of the Failure of the Preceding Wheels and Weights Devices It must not be presumed that the preceding devices shown in this chapter constitute any considerable part of the Wheels and Weights Devices that have been constructed through the hope of attaining Perpetual Motion. Of all the means whereby Perpetual Motion has been sought wheels and weights have been by far the most prolific. There is scarcely a village or a rural community in the civilized world that cannot point out its Perpetual Motion worker, and he generally starts with wheels and weights, though often, after long labor and final failure with wheels and weights, he still exploits other attractive fields of hopeless endeavor. Of the devices of that kind, accounts of which have appeared in scientific journals, or application for patents upon which have been made, and, indeed, patents often granted, it would be possible to write a book of thousands of pages, but to do so would be to no purpose. It is believed by the author that the preceding devices are sufficient to illustrate, and show the controlling features of all the various mechanical contrivances for the utilization of wheels and weights as a means of Self-Motive Power. Countless others could be shown of more or less complicated mechanism, but an examination would disclose the fact that each gets back to some combination of parts well illustrated in the preceding. Also, in endeavoring to express why all wheels and weights devices have failed to work, each essential point of weakness is disclosed in the preceding. Now, why have they failed to work, and wherein are they inherently wrong and unscientific?
