IMPROVEMENT IN ANCHORS. r

Specification forming part of Letters Patent No. 165,036, dated J une 29, 1875; application filed October 1, 1874.

To atl whom it may concern:

Beit known that I, AMos SMrTH, of Bangor, of the county of Penobscot and State of Maine, have invented a new and useful Improvement in Anchors; and do hereby declare thesame to be fully described in the following specification and represented in the accompa-V nying drawings, of whichv Figure l is a perspective view, and Fig. 2 a longitudinal section, and Fig. 3 a front end View, of au anchor provided with my invention.

In this anchor there is applied directly to the shank a surge-reliever, consisting', mainly, of a bail and slide and one or more springs. Furthermore, the arms ofthe anchor stand at, or about at, right angles with the stock, and each has a-duplex nuke, or a fluke with two points, all being' arranged as represented.

In the drawings, A denotes the shank, B B, the arms, and C C the duplex flnkes. Each fluke projects not only above but below its arm, and terminates in two pointsa a, one of which is above and the other below the arm. The fluke is arranged on the front edge of the arm, so that a straight line going through the points of the iiuke shall be at right angles with the arm, all being as shown. A guard brace or rod, D, is fixed to, and extends obliquely f from, each arm at or near its outer end, it

being also fixed to the shank of the anchor. This guard-brace not only aids in supporting the arm, but is mainly to prevent the chain from fouling or catching ou the arm and fluke while the anchor may be in use.

The double pointed flukes, arranged with the arms in manner as described, enable the anchor to be used either side up; and when the anchor is down, it holds by two lukes in stead of by one only, as is the case with the common anchor.

The surge-releveris shown at E as composed not only of a slide, b, and a bail, c, (pivoted to such slide,) but of one or more springs, d c, the slide and spring or springs being arranged to encompass and slide or move on the shank lengthwise. Such stock is provided at itsupper end with a shoulder or head, f, to support the spring or springs. From the said head two rods, g g, are projected, in manner as shown, one being'above and the other below the shank and the spring or springs.

These rods go through the slide, are parallel for some distance to the stock, and finally are bent down and fastened to it, all as shown. They not only serve as guides to the slide, and prevent it from revolving on the stock, but as guards to the spring or springs, to prevent such from being injured or clogged by ewarth or other matters. The surge-reliever, combined directly with the anchor, instead of being fixed on'the deck of avessel, saves the necessity, while the chain or cable is being taken in, ot the usual turning back ot' the windlass while the vessel may be suddenly rising at the bow. The surge-reliever, fixed to the deck, does not cushion the chain while it is being taken in, but, when applied to the anchor, it not only cushions the chain while the vessel is swinging at anchor, but while the chain is being drawn in by the windlas's.

I claim as my invention l. The combination of the anchor .and the` surgereliever E, directly applied to it, all being substantially as described and represented.

2. The combination and arrangement of the guard and guide rods g g with the anchor and the surge-reliever E, applied t0 such anchor, as specified.

3. The anchor having the double-pointed dukes O C arranged with its arms B B, and such arms arranged with the stock A, all substantially as described.

4. The arrangement and combination of the guard-bracesDD with the arms BB, the stock A, and the double-pointed tlukes C G, ar-

ranged as set forth.
