- n. A pulley over which a rope runs. See block and tackle.
Sorry, no etymologies found.
This is a variation of the figure-eight knot, already described, and is used where there is too much rope, or where a simple knot is desired to prevent the rope running through an eye, ring, or tackle-block.
Taking a small boat-mast, the boatswain rapidly lashed the ends of the temporary hammock fast to the spar, and then ropes were carried and secured to the tackle-block in a way that, when all was ready, there was no difficulty in hauling the spar horizontally up, with the temporary hammock and its burden swinging from the spar like a palanquin.
Turk's-head clew, and black as a tarred tackle-block, could be nothing else than the woolly pate of Snowball, the sea-cook!
