1 Claim.

This invention relates to marine anchors, and has for the primary object the provision of a device of this character which will efliciently hold under the most adverse conditions and which will not readily become fouled by an anchor chain or rope and may be easily collapsed when desired without fully detaching any of the parts thereof from each other.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation illustrating a marine anchor constructed in accordance with my invention and showing the anchor in holding position.

Figure 2 is a side elevation illustrating the anchor at rest.

Figure 3 is a top plan View illustrating the anchor and showing in dotted lines the cross arm in a folded position.

Figure 4 is an end elevation illustrating the anchor.

Figure 5 is an enlarged fragmentary sectional view showing the means of releasably securing the cross arm in operative position.

Figure 6 is a detail sectional view showing a portion of the catch means for securing the cross arm in operative position.

Figure 7 is an end View of the cross arm showing the abutment collar thereon.

Referring in detail to the drawings, the numeral 5 indicates an elongated shank having at one end an opening 6 through which an anchor chain ring I may pass and to the latter is connected an anchor chain or rope 8 in the usual way. The other end of the shank 5 carries a pivot pin 9 on which the head ID of the anchor is pivotally mounted.

The head lil consists of a pair of relatively spaced bars H which straddle the shank 5 and are apertured intermediate their ends to receive the pivot pin 9. Integral with the ends of the bars II are fiukes !2.

Each fluke l2 includes a plate-like portion I3 which tapers toward each end, as clearly shown in Figure 3, with its greatest width located closer to one end of the plate-like portion than the other end. This construction of the plate-like portion gives a comparatively broad holding face to the fluke at the end which bites into the bee;

tom of a body of water.

The flukes are arranged in opposed relation and their opposed faces are formed integrally with the ends of the bars ll adjacent the ends of the plate-like portions having the longest taper. The plate-like portions which have the longest taper have their free end portions l4 bent angularly and formed upon the outer faces of the plate-like portions are reinforcing ribs I5, The rein-forcing ribs taper toward opposite ends thereof to facilitate the fiukes biting into the bottom of sand, mud or the like. When the bars H extend at right angles to the shank 5 the angular ends I of the flukes diverge and angularly to the shank. The purpose of the end portions 14 of the flukes is to cause the anchor to readily turn over into an operative or holding position, as shown in Figure 1, when the anchor comes to rest on the bottom of a body of water and is moved relative thereto.

It will be seen that as the anchor moves into holding position one of the fiukes comes in contact with the shank 5 while the other fluke assumes an angular position to the shank and in a position to dig into the mud or sand and the greater the pull on the anchor when in this position the deeper the holding fluke digs into the bottom owing to its angle of inclination with respect to the shank. The end portion of the fluke which is disposed above the surface of the bottom when the anchor is in holding position is such that the end portion I4 is disposed at an angle to the bars as well as to the shank and if engaged by the anchor rope or anchor chain the latter will readily slide thereover and thereby obviate possibility of the anchor becoming fouled by the rope or anchor chain.

The shank 5 adjacent the opening 6 has an opening l6 through which slides the cross arm I1, one end of which is bent angularly, as shown at l8, the purpose of which is to cause the anchor to turn over and assume a holding position when it strikes the bottom. A collar [8 is formed on the cross arm to abut one face of the shank 5 When the cross arm is in an operative position. A pivoted catch I9 is carried by the shank to engage over the collar to hold the latter in abutting position with the shank and consequently retain the cross arm in an operative position. The pivot for the catch is indicated by the character 20. One end portion of the catch is enlarged and offset and bifurcated as shown at 2| to straddle the cross arm when in engagement with the collar 18. The other end of the catch is provided with an opening 22 in which extends a headed pin 23 mounted in an opening 24 of the shank 5. The head of the pin 23 is engaged by a spring element 25 secured on the shank 5, as shown at 2B. The spring element retains the pin 23 in the opening 22, consequently preventing the catch I!) from moving out of holding position on the collar l8 of the cross arm.

A slight flexing of the spring element 25 will permit the pin 23 to move out of the opening 22 of the catch so that the latter may be moved to disengage the bifurcated end portion thereof from the collar l8 and cross arm whereby the latter may be swung into a folded position, as shown in Figure 3, or in a position substantially paralleling the shank 5, permitting the anchor to be conveniently laid at rest upon a. deck or within anchor chocks provided on the deck.

It is believed that the foregoing description, when taken in connection with the drawings, will fully set forth the construction and advantages of this invention to those skilled in the art to which this invention relates, so that further detailed description will not be required.

Having thus described the invention, what I claim is:

A marine anchor comprising a shank having an eye in one end to receive an anchor cable ring, an elongated head pivoted intermediate its ends to the other end of said shank, fiukes integral with the ends of the head and extending at right angles thereto and paralleling each other, a cross arm slidable in the shank, a collar formed on the cross arm, a catch pivotally mounted on the shank and having a bifurcated portion to receive 'the cross arm and engage with the collar to hold
