Figure IV. A, cat-head; B, mortise; F, pivot-pin; I, slot in side plate H to allow the pin to slide, said pin locked by the cam-lever G. d

The letters of reference indicate similar parts in all the figures.

The improvements herein referred to consist in cutting a slot, as shown at B, in Fig. L'through the cathead A, near the outer end, and securing therein the sheave C, said sheave such as is commonly used about a ship, near the inboard-end of the slot B, and securing the toothed cam D by the pin F, which passes horizontally through the cat-head, said cam D to be placed at such a distance that when its longest diameter is down and pressed fiirward by the cam-lock le- Yer G bearing against the pin F, it will gripe the fishchain E, and hold it secure, thus suspending the anchor at any desired height.

The benefit of my invention is in the facility for raising the anchor, as will'he seen.

The usual way of securing the anchor is, a sailor takes his position on the anchor-stop, while the same is suspended over the ships how, and passes a line through the ring; then over the cat-head; The anchor is then raised by the fish-chain, and the chain is secured to a cleat on the cat-head. Such an arrangement as this is both dangerous to the sailor in rough weather and inconvenient.

My invention does away with all danger to the men, and the work can all be done from' the deck. The fish? chain is passed through the ring, then betweenthe sheave and cam, and attached to any hoisting-tackle.

The anchor is then hoisted to any. desired height, the cam closing on the chain and griping it securely. lfhe cam-lever G is then. forced down in place, pressing against the pin F, and securely looking it in .its place. The following isa description of the construction and operation of my said invention.

A slot, as shown at B in Fig. I, is cut through the cat-head, near its outboard-end. A sheave is secured therein by a pin. The cam D is secured at any necessary distance from the sheave by a pin, which projects through and long enough tobe acted on by the lock-lever G. The fish-chain is passed through the anchor-ring, and'the end is passed through between the cam D and sheave C in the slot. The end of the chain is then secured to any hoisting-tackle. Then the chain is drawn up to any desiredheight, the cam D falls on to the chain and grips it securely. To retain the cam D in position, the lock-cam lever, which is shown in Fig. IV, at G, is pressed down, crowding the pin F, and pressing the cam against the chain. The

slot in the side plate allows the pin to act. toward the sheave.

What I claim as my invention, and desire to secure by Letters Patent, i s

The combination of the mortise B in the cat-head A, sheave O, toothed cam D, pin F, and lock-lever G, to be used in combination, for the purpose as described.

CALVIN WARDWELL.
