Show TO USE THE TIDE STILL ANOTHER MACHINE TURM THE OCEANS POWER TO MANS NEEDS by the long row of which mark the graves 0 the schemes of inventors to turn tho tides of the ocean to the uses ot man a new jersey toller has just brought forth a new device which be asserts with confidence presents the solution of the problem the inventor has been working this machine for ten years like all its defunct predecessors doubtless it js a plausible affair born apparently for success but at any rate it has one great and actual advantage it Is the of simplicity in its simplest form the lavont ten Is nothing but a working on the principles of a windmill with a few modifications to suit the differ ent medium upon a fixed vertical axis revolves a ugh wheel from the circumference of this hang a number 0 flanges against which the current flows causing the wheel to revolve now wera these flanges fixed those on one side of the wheel would neutralize those on the other and the wheel would remain stationary it would be like a totally submerged wheel when the paddles on the tipper halt counteract those in the lower the flanges however hang by hinges in i such a manner that when pressed from one side they stand out abight angles to the wheel and receive the face of the current while if the pressure be from the other bide they close up flat against the wheel and offer no resistance thus while on one halt of the wheel the current strikes the faces of the flanges holds them open and causes the wheel to revolve on the other halt it strikes them on the back and keeps them closed the effect 1 the same as with mhd actual paddle wheel one halt of which Is always out of water but the movable flanges have another most important advantage one of the greatest difficulties which haicl confronted inventors who sought to utilize the power of the tides has been in the circumstances that the direction of the force changes every six hours thus the rotation of the water wheel Is reversed which necessitates readjustment pt gears and tends to rack the machine now in the wheel under consideration the direction 0 the rotation is always the same no matter how often that of the propelling force changes for example when the currents are from the north the flanges on the right halt of the wheel which face north will be erect and resistant while those which face south will receive the pressure on their backs and will consequently be closed the movement then will be against the hands of the watch from right to left again when the current flows from the south the flanges on the left elde will be open and those on the right closed with the result that the direction of rotation will be unchanged but the flanges have other peculiarities besides their attachment it when closed up they lay absolutely flush with the wheel the upward pressure of the water would keep them closed during the whole revolution the current having nothing to take the initial grip upon in order to throw them open this difficulty Is obviated by a groove in the face of the flange As soon as it comes to be opposed to the current the effect of te water forcing its way through the groove Is to throw the flange open at once furthermore the flange Is hung at an angle to the spoke in two directions an arrangement which assists the groove in throwing it into position at the first possible moment mhd position of the wheel when in operation would either be on the bottom at a depth sufficient to clear the keels of vessels or else would be se cured to the support of a bridge or hung under a pier when the current Is unobstructed of course the situation chosen would be in an estuary or some other place where the tide runs or less swiftly cogwheels Cog wheels affixed to the top of the axle change the piano of rotation from horizontal to vertical and multiply the velocity as many times as is desired and a band running on a larger wheel transmits the power to the place desired A number of experiments have been made in which a small model is used in it ot was twelve inches there were four rows each containing eight flanges the dimensions men ot each flange were two inches by three the two lower rows revolved on the main axle in one direction from right to iott the two upper rotated independently on an outer axle and their revolution was from left to right by this device additional dit ional power was secured through the principle of torsion as applied in the ordinary hand press the machine was hung from a pier in the harlem river where tha current runs at about four and a halt miles an hour A simple pony brake attached showed a constant pressure of twenty alve pounds calculating from this basis prof jacobus of tha stevens institute deducted that a wheel with a diameter of ten teet would develop twenty five horse power in another experiment the wheel was worked in connection with a patent sewing machine which it drove at the rate of 2500 stitches per minute while in another it threw a of water through an inch diameter tube to a height of over twelve feet i i the inventor asserts wonderful virtues tor hia creation the dimensions of the wheel may be increased indefinitely while there Is no reason that the number ot the discs should be limited to four it can be used he says for any purpose for which power is especially for the generation ot electricity indeed in his ro seato dreams he sees power for the whole electric scheme of now york city lighting street cars telegraph and telephone supplied through the medium of water wheels toy the current of the river at a nominal cost |
