JOHN N. PURDY, OF ST. JOHN, NET/V BRUNSWVIOK, CANADA.

ANCHORCATTER AND FISHER.

SPECIFICATION forming part of Letters Patent No. 284,979, dated September 11, 1883.

I Application filed December 27, 18E2. (No model.)

To all whom it may concern:

Be it known that I, JOHN N. PURDY, of St. John, in the Province of New Brunswick and Dominion of Canada, have invented a new and Improved Anchor (latter and Fisher, of which the following is a full, clear, and exact description.

The object of my invention is to overcome the difficulties heretofore experienced in the catting and fishing of anchors.

The invention consists in combined mechanism composed of a Windlass-barrel mounted upon a frame and bed-plate and fitted to turn upon the cat -head of the ship, so that the anchor, when raised, can be easily moved on board, suitable levers, pawls, and ratchets being used with the barrel, and a fisl1davit, with a hook and guys, being used in connection therewith, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side perspective view of my improved anchor-catting apparatus. Fig. 2 is a plan view of the same.

A is the ships cat-head. B is the cattingchain. 0 is a bed-plate bolted to the cat-head, and D is a suitable iron frame, attached to the bed-plate by a bolt, a, so that the frame may turn freely. E is the windlassbarrel, fitted in suitable journals on the frame D, and provided at its ends with ratchets b, that are engaged by pawl c. F are the Windlass-levers. G is the anchor, and H is the fish-davit, guyed as usual, and provided with a pennant, 1', fishhook e, and suitable falls and blocks. A latch or bolt of suitable character is used to retain the frame D and Windlass in position.

In operation, after the anchor is hove up to the hawse-pipe by the main Windlass, the block upon the cat-chain B is hooked into the ring of the anchor, and the anchor then hove to the cat-head by the Windlass E. The stopper is then passed through the ring of the anchor and made fast to its proper place, the chain B is slackened to liberate the catter,and passed over the ends of the barrel E. The holdingbolt holding the frame D is then removed,and the Windlass E swung around to face the davit H, and the bolt again put in place. The fishpennant I is then placed around the barrel of the catter and the hook e at the other end of the pennant hooked upon the fluke of the anchor, and the anchor is then hove up by the 'catter until high enough to swing over the rail, then, by slackening the guy of the fishdavit, the anchor will swing over the rail to its proper place and can be made fast.

The advantages of this mechanism are as follows: First, it does away withall incumbrances, such as wooden frames in the forecastle; second, there is no necessity of cutting holes through the ships top-gallant forecastle, and third, the ships Windlass or capstan is not required in the operation of catting the anchor, as all the necessary power may be applied by means of the small barrel.

The whole apparatus requires but little space, and when a ship is at sea the Windlass and its frame can be removed from the cathead and stowed away.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The apparatus for catting and fishing anchors, consisting of the cat-head A, turntable D, mounted above the latter, the windlass E, chain B, passed around the barrel of the Windlass and capable of connection to the anchor, and davit H, with means also capable of connection to the anchor, said Windlass be ing adapted for operation so as to face the davit, substantially as and for the purpose set forth.

- 2. The combination of the Windlass E, the chain B, coiled around the barrel of the latter, and capable of connection to the anchor, the

bed-plate O, and the turn-table D, supporting the Windlass and pivoted upon the bed-plate, substantially as and for the purpose set forth.

3. The combination of the. cat-head A, bedplate 0, secured across or upon the latter, turn-table D, pivoted up on the bed-plate, windlass E, mounted upon the turn-table, and the chain B, coiled around the barrel of the windlass and adapted to be connected to the anchor, substantially as and for the purpose specified.
