The'drum is composed of a metal plate l bent to forma cylinder 16', a pair of end disks 19 andbolts 20, these parts being apart to provide a slot 18. on the cable 9 is hooked. Also engaged witlrthis slot,'is a hook' '2 l on the end; of a spiral spring which is located within the cylinder :16', the inner end of said spring having-any appropr ate connection with a :shaft 2Q upon which the drum rot-atably supported.

takes place. 'E'venin exceptionally rough water, the machine will operate advantageously, as thefloat-sj'iare alloweda great deal of 'leeway in their movements, due to the slack 'ofthecables 8. Moreover, the

shaping of the floats is such that the action of the water laterally against them hasa tendency to produce upward movements thereof, whieh'isradvantageous as the more vertical movements the floats possess, the greater the efliciency of the machine. Each oat isofcircular outline and my reason for makingthe top ofthe float of greater diameter than its bottom and providing it with an outwardly inclined. sidewall, is that when a fast rush of water or a: breaker comes in The ends of the contact with the float, the force of the water 7 is deflected by the angle of the side; wall, lifting the float to thetop of thewater in stead of forcing it in the direction in which thewater isflowing. My reason for having anchorage loops 7 at the outer edgeof the tripoit-the float and also loops 7 at itsbottom, and connecting cables 8 with top loops 7 and short cable's 8 with loops 7-," and with cables 8 at points'spaced from the float is that when the float gets to the full'length of the anchor cable 8,1the float tips upward," being canted jin, this'manner by the'pull on the bottomcablepS, thus 'causingthe water to lift the float and allowing the water to pass under such float, l Vithout this bottom anchorage, breakers would submer e the float and the force of ,thlejwa'ter wouldfso turn said float about a horizontal axis as to permit the fullforceo'f the breakers to come in. contact with the-top face of said floatL; 5

Thiswould have a tendencyto break the V anchorage or otherwisedamage the machine. Loose anchorage isprovided for each float so that the latter may move around'in any direction, according to the movement of the water,and as longasthese floats are 1nov-- in}; in any direction from'a central posi low the float, thereby tilting theqfloat upwardly and causing the water to slide'underneath, without any "great; resistance against the float to cause breakage or damage.

In tests of afull sized workingwmachine anchoring cables, my experience was thatin lessthan ten minutes after placing the floats on the ocean, three acetylene-welded anchors on the floats, for the anchoring cables, were ripped off. This however, was before 1 conceived the idea of providing'the arrangement of cables herein disclosed, in which the i main anehoringcables are connected with the upper portion of the float and the auxiliary cables to the bottom portion thereof. After making this change, no furth'er diiiiculty'was encountered with regardto'nppmg loose of:

Before the cable anchors from the floats. the use of this improved arrangement of cables, the flat sides of the floats would often receive the directforce of the breakers, but

with said arrangement of cables, this is im- I possible and the floats are so controlled that at all times, the water, even, of forcible and high breakers, may slidefreel'y under the floats, without any severe tendency toward the breaking of cable anchors or cables.

On account of the good res'ults obtainable from the details disclosed, they arepreferably followed; However, withinthe-scope from said drum for rotating it, a float on the lower end of said cable having a relatively large diameter at its top, a comparatively small diameter at its bottom and an inwardly declined side wall from said top to said bottom, and anchoring cables connected with the supporting structure and extending radially from the float to said structure, said cables having bifurcated lower ends connected with the periphery of the float at the upper and lower edges of said. side wall. re-
