Show Pump That Is Close to Perpetual Motion A WATER pumping machine which corner as close to perpetual motion as it is possible pos-sible to come has just been patented by Joseph A. Yasbik of New York. The inventor makes no claim to having constructed a perpetual motion machine, but he docs claim to have devised one which makes use of Its own energy in helping Its own motion. It Is an ingenious and very simple sim-ple pump, which works well on a small scale, but has not yet been tested on a scale large enough to enable final Judgment as to whether it Is superior supe-rior to other pumping machines. The diagram printed herewith gives a good idea of this device. It will be seen that there Is a motor set In motion by a coiled spring and geai ed by cogwheels and a chain to a walking beam. On this beam Is a slot In which a crank works to and fro, working the piston rod of a pump up and down The water from the pump Is raised to a reservoir, whence It flows down pipes into a trough, from which it can bo piped in any direction. direc-tion. The striking feature of the machine is, however, the water-wheel surrounding the spring on the left. This wheel is set In motion by water flow ing from the reservoir, and when It turns It winds up the spring. By a sstcm of vahes the flow from the reservoir 1b regulated so that as soon as the spring has run down to a certain point the water starts to turn the wheel, thereby tf , Q rewinding the spring and cutting off the water again when it Is rewound There Is also a flywheel, fly-wheel, and the whole is mounted bv standards on a solid base. Mr. Yasbik claims that his invention Is cheap in installation, has a minimum number of parts, needs little attention and Is practically foolproof. |
