English practice on First Rates was to have four anchors, two big bowers and two "stream" anchors.
The rode for the anchors was stout stuff, 36, 40, 48" circumference hawser-laid line. This was not the sort of stuff you whip a few turns around a capstan and winch in.
Instead, a smaller line, the traveler, was fitted to a block bent on in the head of the ship, abaft of the stem. The traveler was then run around the capstan, and the ends spliced together into a continuous run of line, and run along side the anchor rode.
To heave in the anchor, the traveler was "nipped" to the rode with small lines about 18-24" apart. The capstan bars were put in, and the pawl set right, and sailors bent to the capstan bars and heaved away.
As the rode came aboard, additional nips bound it to the traveler. As the rode reached the hatch leading to the cable tier, the ships boys would loose the nips to carry them forward. The more nips on the rode, the better it held, so you wanted on for as long as possible. Which could mean right into the radius of the capstan bars. Which would get boys under the feet of the sailors heaving the capstan.
The boys had to learn how to snap the nip so it would whip around the rode and traveler. They'd also have a technique for whipping the nips out, too. Which is how wee nippers were also whippersnappers, too.
