PERPETUAL MOTION.

INVENTORS’ IDEAS. Vhcnovrr an inventor of tc porpetynl motion contrivance seeks a patent nffl y rl' an vr A f ieri >'‘ m r Paper ) tho Patent OfiSce politely asks for a working model as a preliminary to its further consiwratum. The working model is in duo time presented. It fails to work ?o U rV b° n thlS fMt is shmvn tho inventor IS by no means persuaded that his ™rol 1S n °V a g00(i one - ' The machine nrvTnX n9ed3 i S ° mo di " ht alteration in This PoH- T y a Practioal success. J his sort of business is hard for the professional model maker. The pemetinl Sirnt 1311 I s . confident that his idea represents a gigantic fortune. He Is reluctant to trust the m®del make? with it, lest the latter bo tempted to steal it Sometimes h 0 domaiids that the model maker shall take a solemn oath not to reveal the secret,. Ono Jf the least complex perpetual motion devices is that of a spring that winds up another spring while itself running down, and vice versa reciprocally withS C T + flg - u hen this hw been reduced to really practical shape it will be possible to make clock that will go forever without winding. Another is a wheel pivoted on a point at its centre, with a metal ball running around its periphery. According to nil reason and common sense, the hall, once etartftrj, ought to keep on .running for a million, years; but somehow, owing to a slight defect in the working model it doesn t. On a pivoted board) a little car runs back and forth. When it reaches one end it jeleases b spring that tilts the board the opposite way, so that the car runs back to the end from ■which it started, where it hits (mother spring and tilts tho board the other way, is sent back again and so on ad infinitum. Here’s another. Down an inclined plane six little cars run furnishing energy whereby three little cars are hoisted to the same starting point. There are always six cars going down and only thr-v going up, and it would seem a.s if the contrivance ought lo keep the cars going until tho wheels wore out.
