Show A PERPETUAL MOTION PUMP. ConTertlng tuo Rolling Sea Waves Into rover for Pumping Water. Underneath the pier of the Eond Wave Power company at Ocean Grove, N. J., a mammoth iron egg floats upon the top of the waves. In mild weather the egg bobs up serenely, rising to a height of about fourteen inches above the dead level of the sea, but when the weather is rough and great rollers come rushing in the egg rises forcefully upward five feet or more. It cannot get loose, for it is made fast to the pier by long, strong anus of iron. Up from the top of the mammoth egg a rope runs, and after it has passed over a pulloy it stretches on shoreward, and at last enters a wooden building situated npon the beach. In the building is a pump, and the rope is in connection with it. Tho pump is lifting lift-ing about 3,000 gallons of water animate, anim-ate, raising it distances equivalent to the height of the waves. The explanation of the apparatus and the work it is doing is that Mr. N. O. Dond, whose namesake the Bond Wave Power company is, has successfully completed an experiment undertaken primarily to determine if it were possible possi-ble to make the ocean, by the motion of its waves, pump enough of itself into Wesley lake to make that lake a body of salt water. There are people living in Asbnry Park and Ocean Grove who, considering that the sources of tho water of Wesloy lake are in the swamp lands, judge that tho lake is to some extent a health menacing body of water, and they have for some time wished that it might be salted. Mr. Bond says that ho will have no difficulty in making Lake Wesley Wes-ley salt, and he expects to do it. He says that he is perfectly satisfied that bin new wave machine will not only do the work which it was especially devised to do, but he is also assured that it will be found a valuable machine for doing other things which need to be done economically. eco-nomically. He says that the machine is strong enough to work comfortably in the roughest weather and that it is built with an especial view to making it run with very little supervision. He says that the wave gate which is in use as the motive power of the street sprink- ling systom at Ocean Park ran all tnrough the winter of 1889-90 without getting out of order, and that its operations were not in the slightest interfered with by the great storm, which, it will be recalled, re-called, was spoken of as "the greatest storm for- thirty years." Tho wave egg, Mr Bond says, will be as little liable to disarrangement by heavy weather as the wave gate was. The new machine may be used where-ever where-ever waves rise and fall, and there need not necessarily be a pior to hold it to its work. It may be kept ia place by piles quite as well as by a pier, for, while the force of a great wave is immense, it 1b not so exerted upon the egg as to give a shock, such, for example, as the shock of a cannon ball. Tho wave egg may be made as its uses may demand. The one in operation at Ocean Grove has a major diameter of ton foet, a minor diameter of seven feet, and its weight, conjoined with the arms by which it . is fastened to tho pier, is alxmt two tons. Tho length of the arms is thirty-three feet. New York Times. |
