Abstract

A manual marine barge winch includes a housing, a winch-line holding drum mounted for rotation on the housing, a winch-line coupled to the drum and adapted to be wound onto and off of the holding drum to tension and pay out the winch, a drum drive for rotating the drum to tension and to pay out the winch line, and at least one winch-line engaging roller adapted to engage the winch line at least during tensioning of the winch. Preferably at least one of the winch line engaging rollers is a powered or driven roller for driving the winch line.

Claims

1. A marine winch comprising:

A housing;

A winch-line holding drum mounted for rotation on the housing;

A winch-line coupled to the drum and adapted to be wound onto and off of the holding drum to tension and pay out the winch;

A drum drive for rotating the drum to tension and to pay out the winch line;

A winch-line engaging, driven roller adapted to engage and drive the winch line at least during tensioning of the winch.

2. The marine winch of claim 1 wherein the housing comprises a pair of side plates and the holding drum and winch-line engaging driven roller are mounted to the side plates.

3. The marine winch of claim 1 wherein the winch line is a wire rope and the winch line holding drum is a grooved drum holding the wire rope.

4. The marine winch of claim 1 wherein the drum drive includes a drum gear attached to the holding drum and a drive pinion engaging the drum gear and wherein the winch-line engaging roller is coupled to the drive pinion.

5. The marine winch of claim 1 wherein the drum drive includes a drum gear attached to the holding drum and a drive pinion engaging the drum gear and wherein the winch-line engaging roller is co-axial with the drive pinion.

6. The marine winch of claim 5 wherein the housing comprises a pair of side plates and the holding drum, the drum drive and winch-line engaging driven roller are mounted to the side plates.

7. The marine winch of claim 6 wherein the winch line is a wire rope and the winch line holding drum is a grooved drum holding the wire rope.

8. The marine winch of claim 7 wherein the drum drive includes a hand wheel for manual rotation.

9. The marine winch of claim 8 further including a tension holding ratchet pawl mechanism coupled to the drum.

10. The marine winch of claim 1 further including at least a second winch-line engaging, driven roller adapted to engage and drive the winch line at least during tensioning of the winch.

19. The marine winch of claim 1 further including at least a second wire rope engaging, driven roller adapted to engage and drive the wire rope at least during tensioning of the winch.

11. A manual marine winch comprising

A housing;

A wire rope holding drum mounted for rotation on the housing;

A wire rope coupled to the drum and adapted to be wound onto and off of the holding drum to tension and pay out the winch;

A drum gear coupled to the drum to rotate the drum;

A wire rope engaging, driven roller adapted to engage and drive the wire rope at least during tensioning of the winch; and

A common manual drive source for the drum gear and the driven roller.

12. The manual marine winch of claim 11 wherein the housing comprises a pair of side plates and the holding drum and winch-line engaging driven roller are mounted to the side plates.

13. The manual marine winch of claim 11 further including a drive pinion engaging the drum gear coupled to the common manual drive source and wherein the driven wire rope engaging roller is coupled to the drive pinion.

14. The manual marine winch of claim 11 further including a drive pinion engaging the drum gear coupled to the common manual drive source and wherein the driven wire rope engaging roller is co-axial with the drive pinion.

15. The manual marine winch of claim 14 wherein the housing comprises a pair of side plates and the holding drum, the drum drive and wire rope engaging driven roller are mounted to the side plates.

16. The manual marine winch of claim 15 wherein the holding drum is a grooved drum holding the wire rope.

17. The manual marine winch of claim 16 wherein the common manual drive source includes a hand wheel for manual rotation.

18. The manual marine winch of claim 17 further including a tension holding ratchet pawl mechanism coupled to the drum.

20. A manual marine winch comprising

A housing;

A wire rope holding drum mounted for rotation on the housing;

A wire rope coupled to the drum and adapted to be wound onto and off of the holding drum to tension and pay out the winch;

A plurality of wire rope engaging rollers coupled to the housing space circumferentially about the drum, wherein each roller is adapted to engage the wire rope at least during tensioning of the winch.
