ANCHOR FOR ANCHORING VESSELS.

SPECIFICATION forming part of Letters Patent No. 352,481, dated November 9, 1886,

Application filed June 9, 1886. Serial No. 204,570. (No model.)

To all whom it may cancer-m Be it known that I, Banners D. MONTAGUE, a citizen of the United States, residing at Hopedale, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Anchors and Modes of AnchoringVessels, (for which Ihave not obtained a patentin any country,) of which the following is a specification.

My invention relates to an improved mode of anchoring vessels, and embodies an anchor of improved construction, together with certain details in construction and combination, hereinafter fully set forth.

In describing my invention in detail reference is made to the accompanying drawings, which form a part of this specification, in which- Figure 1 shows a central longitudinal vertical section of a light-ship at anchor, illustrating my invention. Fig. 2 is an elevation of my improved anchor, showing the flukes spread out. Fig. 3 is an elevation of the same, showing the flukes folded up close to the anchor-shank. Fig. 4. is a bottom view of the anchor, illustrating it as constructed with three flukes; and Fig. 5is an enlarged view showing a portion of the anchor-shank, hawser, and leading-chains.

Similar letters indicate corresponding parts in all the figures.

A is the anchor-shank, provided at its upper end with the hawser-ring B, in the usual manner, and at its lower end with the flukes C. These flukes are pivoted to the anchorshank by the pivotal bolts a independently of each other, each fluke being adapted to be folded up against the anchor-shank separately from the others, as shown in Fig.- 3. The flukes at their inner ends are provided with the, shoulders b, which, coming against the anchor-shank,-prevent the flukes from opening beyond a given distancefor instance, that shown in Fig. 2. Each fluke has a leading chain, e, attached to its outer end, as shown at it. These leading-chains pass through the rings (1, attached to the anchor-shank A at a point preferably just above where the points of the folded flukes touch said anchor-shank, as seen in Fig. 3. The leading-chains e are joined together at 9, above the ring B, and thence continue some distance as asingle leading-chain, f, which is attached to the hawser F at 71. pass above the deck when the open anchor The leading-chainf is long enough to p hangs suspended just below the bottom of the i chain f is above the deck, at which time the open anchor hangs just below the keel, the

leading-chains e hanging loosely, as shown in Fig. 2. The leading-chain f is now hauled up, and this draws up the leading-chains e, attached thereto, through the rings d, which operation simultaneously draws all the flukes 0 close up to the anchor-shank, which they closely hug as long as the leading-chain f is kept taut. The folded anchor is now readily raised to the deck through the hawser-pipe E.- To anchor the vessel this operation is simply reversed. The folded anchor is passed down through and below the hawser-pipe, the leading-chain f is then let go, and the flukes of their own weight fall open, as shown in Figs. 2 and 4. WVhen the bottom of the sea is reached and the anchonshank falls'over, the lower flukes dig into the bottom and hold the vessel,whether the upper flukes remain spread out or not.

By constructing the anchor in the manner described the hawser-pipe may be made much smaller in diameter than would be necessary were a rigid anchor used.

Some advantages of anchoring vessels amidships in the manner described may be stated as follows: The vessel at anchor will ride on the crest of waves without shipping water. It may be anchored in water of unlimited depth and will be held steady by the center in case of a storm, instead of being drawn under by "the bow, as is often the case when vessels are chains e, attached to said flukes, and the lead- ,ing'chains e and at the other to the hawser F,

anchored in the ordinary way from the bow. Thus much greater safety is attained. Again, when sailing or drifting in a gale, the anchor can be readily dropped down any desired distance below the keel amidships, and will thus answer as a drag or low ballast to steady the ship and keep her upright. Furthermore, telegraph-cable light-ships provided with this mode of anchoring will outride any storm, and in case of the approach of an iceberg or other similar source of danger can readilybuoy their cables, slip their moorings, and sail away until the threatened danger is passed, and then return to anchor again.

What I claim as my invention is 1. The anchor-shank A, provided with the flukes G, pivoted thereto independently of each other, in combination with the leadinging-chain f, attached at one end to said leadsu'bst-antiall'y as-described. 9

2. The combination of the anchor-shank A,

provided at one end with the ring B, the hawser F, attached to said ring, the flukes C, pivoted to the opposite end ol said anchor-shank independently of each other, the guide-rings (I, attached to said anchor'shank, and the leading-chains 6, attached to the outer end of said flukes and passing through said guiderings d, whereby said fiukes may be drawn close up to said anchor-shank, substantially as set forth.

3. The vessel D, provided with the hawserpipe E, passing through the bottom of said vessel amidships, the hawser F, the anchor consisting, essentially, of the shank A and independently-pivoted flukes O, the leadingchains 0, attached to said flukes, and the leading-chain f, attached to said leading-chains e 0 and to said hawser F, the whole combined and operating substantially as described.
