[from the Ang.-Sax. windles]. A machine erected in the fore-part of a ship which serves to ride by, as well as heave in the cable. It is composed of the carrick-heads or windlass-heads, which are secured to all the deck-beams beneath, and backed by long sleeper knees on deck. The main-piece is whelped like the capstan, and suspended at its ends by powerful spindles falling into metal bearings in the carrick or windlass heads. Amidships it is supported by chocks, where it is also furnished with a course of windlass-pawls, four taking at separate angles on a main ratchet, and bearing on one quadrant of the circumference. The cables have three turns round this main-piece (one cable on each side): holes are cut for the windlass-bars in each eighth of the squared sides. The windlass may be said also to be supported or reinforced by the pawl-bitts, two powerful bitt-heads at the centre.
