The anchor is held in place by two chains, a and b, termed the cat-stopper and shank vainter respectively, each of which is fitted with a long link at one end. A bolt b, about 5 or 6 inches long, is fixed on the side of the cathead, on a hinge at its lower end; it is held in the upright position by another bolt c, which passes through the cathead, and is worked by a lever d; d is provided with a hole at the end for a lanyard, so that two or three men can pull it. This whole arrangement is termed a slip-stopper. A somewhat similar combination of bolts and levers is fitted close tot he bill-board D, e being a short bolt secured at its lower end with a hinge to the ship's side; and f a hooked lever which holds it in its upright position; f has a socket at its inboard end, to which a shifting arm, provided with a lanyard like the lever d, is fitted." — Encyclopedia Britanica, 1893

"The anchor is represented in the position in which it lies on the ground just before taking hold. The shank is made in one forging, is of rectangular section, having a shoulder for the stock to fit against, and is increased both in thickness and area at the crown; the arms with the palms are forged in one piece, and then bent to the required shape; one of the arms is passed through a hole in the crown and is kept in position by a bolt screwed through the end of the crown, so that its point reaches a little way into an indent made for it in the round part at the back of the arms." — Encyclopedia Britanica, 1893

"The stock is of iron in large as well as small anchors, and is made with a mortice, to fit over the shank instead of passing through it. It is somewhat heavier than the stocks of other anchors; the arms are shorter than usual in proportion to the length of the shank, and are of a wedge shape, varying in sharpness from the throat to the head of the palms; the back part of the arms is parallel from palm to palm; the palm is double concave on the front, and has a small border at the edge for confining the soil through which it is dragged." — Encyclopedia Britanica, 1893
