Claims
- 1. An anchor orientating device characterised by including a body member elongated along an axis of the device adapted at a forward end for attachment to a cable and at an after end for attachment to an anchor shank or a cable and a transverse cam member attached to the body member and so adapted that the cam member can react with a first cylindrical firm surface to cause operative orientation of the device.
- 2. An anchor orientating device as claimed in claim 1, characterised in that the cam member bears a peripheral edge forming a stability creating surface means at one side of said axis and a non-stable second surface portion or peak at an opposite side of said axis whereby, on being dragged over a cylindrical firm surface with said second surface portion in contact with said firm surface, the device tends to topple away from the peak and roll on said cam member to bring the stability creating surface means into stable contact with said firm surface.
- 3. An anchor orientatin device as claimed in claim 2, characterised in that the stability creating surface means comprises a land.
- 4. An anchor orientating device as claimed in claim 2, characterised in that the stability creating surface means is closer to the axis of the device than the peak.
- 5. An anchor orientation device as claimed in claim 2, characterized in that secondary reaction surface means are provided and arranged to react with a second cylindrical firm surface of lesser diameter than said first cylindrical surface to cause tilting of the device.
- 6. An anchor orientating device as claimed in claim 5, characterized in that the secondary reaction surface means comprises an edge of a plate member which edge extends laterally beyond the stability creating surface means of the cam member.
- 7. An anchor orientating device as claimed in claim 6, characterized in that said edge includes an outer edge surface and a bevel surface flanking said outer edge surface.
- 8. An anchor orientating device as claimed in claim 7, characterized in that said outer edge surface is off-set from the vertical mid-plane of the device.
- 9. An anchor orientating device as claimed in claim 1, characterized in that a peak of the cam member is located forward of the stability creating surface means.
- 10. An anchor orientating device as claimed in claim 1, characterized in that the peripheral edge of the cam member is substantially contained in a plane.
- 11. An anchor orientating device as claimed in 10, characterized in that the plane of the periphery of the cam member is inclined to the axis of the device.
- 12. An anchor orientating device as claimed in claim 11, characterized in that the plane of the periphery of the cam member is inclined to the axis of the device in the range 40.degree. to 80.degree. and preferably 50.degree. to 65.degree..
- 13. An anchor orientating device as claimed in claim 1, characterized in that the cam member periphery is of cardioid shape.
- 14. An anchor orientating device as claimed in claim 1, characterized in that secondary reaction surface means are provided and arranged to react with a second cylindrical firm surface of lesser diameter than said first cylindrical surface to cause tilting of the device.
- 15. An anchor orientating device as claimed in claim 14, characterized in that the secondary reaction surface means operatively react with a firm cylindrical surface of a diameter less than a predetermined size while precluding operation of said cam member with this cylindrical surface, and in that said cam member operatively reacts with a firm cylindrical surface of a diameter greater than a predetermined size while precluding engagemment of said secondary reaction surface means with the latter cylindrical surface.
- 16. An anchor orientation device as claimed in claim 1, characterized in that an aperture is provided at the after end of the body member to receive a joining shackle and arranged such that the shackle has limited degree of rotational freedom about said axis relative to the body member.
