Claims10
In an anchoring apparatus having a housing;
- a support extending through said housing;
- a fluke movably mounted on said support for movement relative to said housing between a sea bed engaging position and a release position, the improvement comprising:
- a cam assembly movably mounted on said support for movement between a first position and a second position, said cam assembly having a first portion extending through said housing and being movable relative to said fluke;
- a cam roller resiliently mounted with said housing for movement toward and away from said cam assembly, said cam roller being engageable with said first portion of said cam assembly;
- spring means connected to said roller to bias said roller into engagement with said first portion and for releasably holding said cam assembly in said first position;
- actuating means connected to said cam roller and being selectively operable to effect movement of said cam roller away from said cam assembly to permit said cam assembly to move to said second position, the release of the operation of said actuating means to permit said spring means to urge said cam roller against the first portion of said cam assembly effecting the return of said cam assembly to said first position;
- and
- limit means for limiting movement of said fluke relative to said cam assembly, said limit means being operable to permit said fluke to move to said release position when said cam assembly moves to said second position and to effect a movement of said fluke to said sea engaging position when said cam assembly moves from said second position to said first position.
