An apparatus for providing mechanical force comprising:
- a polygonal upper frame member formed of a plurality of individual elongated linear segments each having distal ends engaged to distal ends of adjacent said segments, said upper frame defining an upper circumscribed area;
- a polygonal lower frame member formed of a plurality of individual elongated linear segments each having distal ends engaged to distal ends of adjacent said segments, said upper frame defining an lower circumscribed area;
- means for rotational angled engagement of said distal ends of said linear segments forming said upper frame, to adjacent said ends of said linear members;
- means for rotational angled engagement of said distal ends of said linear segments forming said lower frame, to adjacent said ends of said linear members;
- means for rotational support of said upper frame a fixed distance from a rotational support with said lower frame;
- a plurality of pairs of upper circular planar members with one each of said pairs rotationally engaged at center portions of each said elongated members of said upper frame;
- a plurality of pairs of lower circular planar members with one each of said pairs rotationally engaged at center sections of said elongated segments of said lower frame;
- a first angle formed between each of said pair of upper circular planar members thereby forming a narrowing path therebetween, said narrowing path proceeding from a widest point outside said upper circumscribed area to a narrowest point inside said respective upper circumscribed area;
- an equal second angle to said first angle formed between each of said pair of lower circular planar members thereby forming a widening path therebetween, said widening path proceeding from a narrowest point inside said lower circumscribed area to a widest point outside said respective lower circumscribed area;
- a plurality of chains engaged for rotation with said upper circular planar members and said lower circular planar members whereby said chains and said circular planar members rotate at substantially a same speed;
- a plurality of evenly spaced floatation members having endwalls in sealed engagement to a collapsible sidewall thereby defining an interior cavity;
- said floatation members having an enlarged dimension with a maximum volume and a collapsed dimension of a minimum volume;
- means of engagement of one of each endwall to a respective one of a pair of said plurality of chains, with each floatation member of each pair of chains aligned with adjacent floatation members of adjacent pairs of chains;
- said floatation members engaged to each said pair of chains aligned with those of adjacent said pairs of chains for an inline rotation around said upper and lower frames and therebetween;
- said narrowing path defined by said rotating upper circular planar members providing means to force said endwalls to collapse said sidewall thereby moving said floatation member to said collapsed dimension;
- means to maintain said floatation members in said collapsed dimension;
- means to release said floatation members from said collapsed dimension prior to travel through said widening path;
- and
- whereby said floatation members in said enlarged state impart an upward force to said plurality of chains.
