Application filed December 13, 1918, Serial No. 266,546. Renewed August 14, 1920. Serial No. 403,510.
T 0 all whom it may concern Be it known that I, AARON WV. H. WAR- SGHAVSKY, a citizen of the United States of America, and a resident of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improveinents in WVave-Motors, of which the following is a specification.
The present invention relates generally to wave motors and its main feature resides in means for utilizing the fall as well as the rise of waves. Another feature of the invention is the arrangement of the parts in units of such character that any number of units maybe grouped for actuation of a power translating device, such as a generator. A still further feature of the invention resides in the fact that a floating structure is used, on which all the mechanism is mounted, together with means for adjusting said structure with respect to the surface of the water. V
The invention is embodied in a concrete and preferred form in the accompanying drawings, in which- Figure 1 is a top plan View of a single unit showing one exemplification of the invention.
Fig. 2 is a view in elevation, with parts broken away, of the unit shown in Fig. 1.
Fig. 3 is a detail view, partly in section, of the floating and rotatable members of the unit shown in Figs. 1 and 2.
Fig. 4 is a fragmentary sectional View on the line 4-4 of Fig. 3.
Fig. 5 is a detail view partly in section of a modified form of the invention shown in Fig. 3. V
Fig. 6 is a view, in elevation, of a group of units arranged to actuate a single power translating device.
Considering first the invention as dis closed in Figs. 1 to 4. 1 indicates a floating structure constructed of steel beams and This floating structure braces as indicated. is carried by a number of tanks or pontoons 2 and is rendered unresponsive to wave motion by suitable flexible connections 3 that are anehoredat the bottom of the ocean or lake, the structure being immersed to a considerable depth and below the action of the waves and below the point of buoyancy of the structure. The cables 3 are wound on sheaves 4 mounted on shafts 5 geared together by sh 6 nd bev l g s .7? y.
these means, all of the cables may be wound or unwound in unison, a motor 8 and a reduction gear 9 being conveniently used to efiect rotation of shaft 6. Suitable means, such as ratchets and pawls (not shown), maybe used to cables.
10 indicates a floating member free to rise and fallin response to the motion of waves. In this instance, this member consists of a small tank ll that forms a buoyant member and slides 12 that engage in guides 13 of the frame work of the device. It will be understood that wave motion will cause the floating member 10 to reciprocate in its guides, the, amplitude of this reciprocating motion depending upon the action of the waves. The means for utilizing both the up and down stroke of this floating member take, in this instance, the following form. '14 and 15 indicate two transmission members here consisting of sheaves around which are passed cables 16, the free ends of which are attached at the upper and lower ends of member 10. Said members 14 and 15 are ldly mounted for rotation on driver shafts 17 and 18, a ball clutch 19 being in terposed between transmission member 14 and shaft 17 and another ball clutch 20 being interposed between transmission member 15 and shaft 18. The two'clutches 19 and 20 are arranged to act in opposite directions with respect to each other so that, when member 10 rises, both of the transmission members 14 and 15 are rotated and shaft 18 is turned in the direction indicated by the arrow, shaft 17, however, remaining stationary. On the down stroke of member 10,
7 both transmission members 14 and 15 are again rotated but in the opposite direction and shaft 17 is now turned in the direction indicated by the arrow, while shaft 18 re mains stationary. It will be observed that shafts 17 and 18 turn in the same direction but thatthey are operated on different prevent unwinding of the with transmission gears 1% and 15* which latter are connected by means of clutches 19 and 20 to shafts 17 and 18, the arrangement of the clutch being the same as that shown in'Fig. 3. It will be understood that by the means described both the up and down stroke of the floating member may be uti lized for the production of power and that by providing a great many units the accumulation of power may be made very considerable. In Fig. 6 is shown, in diagram matic form, how a number of such units may be combined. It will, of course, be understood that shafts 17 and 18 may be of considerable length and that any numbervof clutches, transmission members and floating members may be used in connection with said shafts; and that the irregular action of a number of reciprocating floating members, due to difference 1n wave, heightand length,
will in nowise cause interference but that said shafts will simply accumulate all the power supplied by any of the devicesconnected therewith. Similarly, a number of units may be grouped one behind the other in the manner indicated in Fig; 6! In this form of the invention, shafts 17 and 18 of the same unit are connectedby meansiof pulleys '32'and belts 33; and shafts 18 and 17 r of adjacent units are connected by means of pulleys 341 and 35 and belt 36. The power produced by the units may then betaken off any one or more of the shafts andpreferably as shown in Fig, 6; Pulleys 37 and 38 may constitute the means in connection with belts 39 and 10 whereby power will be transmitted to shaft 41 of power translating device21. Any one of the floating members,
if it is desired to render it inoperative, may be raised and held on a support 1 2.
