3 claims. (01. 114-208) I This invention relatesgto ships anchoraand is a continuation-in-part of my previously f led application, Serial No, 613,872, filedAugust -31, 1945, and now abandoned.

The object of this invention is to provide a ships anchor which, due to its peculiar construction, is capable of great holding power coupled with extreme lightness-in weight.

A further object of the invention is toprovide such an anchor which has but a single holding member, yet will come to rest upon one; side or the other and is capable of holding with equal power regardless of the side which is down.

Another object of the inventionis to provide such an anchor which is provided with-means to force its holding memberinto the-bottom, this action being continued after purchase-is first made giving the anchor a tendency "to increase its purchase.

The inventioniurther contemplates an anchor;

in which the holding member is of such shape that the further the holdingmember penetrates into the bottom, the greater the area presented to withstand pressure, which'willinaterially decrease the possibility of pull-outs.

In addition to lightness of weight and ease of handling, the invention provides an anchor :which .will lie relatively fiat on the deckor may'bemore conveniently stowed.

Other objects of the invention will become apparent from the following'de's'cription taken in the lightof-the drawings whiohaccompany and -form part of this specification.

In the drawings:

Figure 1 is an end view of an anchor embodying the principles of the present invention, the anchor being shown partially embedded in a bottom to illustrate its manner of holding;

Figure 2 is a perspective view of the anchor;

Figure 3 is an end view of the lower portion of the anchor;

Figure 4 is an end view similar to Figure 1 but showing a modified form of anchor;

Figure 5 is a perspective view of the anchor shown in Figure 4; and

Figure 6 is a vertical section through the lower portion of the modified form of anchor.

Referring to the drawings in detail, and first adverting to that form of the invention shown in Figures 1 to 3 inclusive, the anchor consists of an open-frame shank I and a holding member 2, the shank and holding member being secured together by means of a hinge connection 3.

The shank I is formed from a metal rod, bent at its center to form an eye 4 with the arms points of the'holdin'g member may pass" 2 5 and 6 of the rod diverging irom the eye-dbwnward toa point near their ends. The lower .por-

tionsof the arms are bent to converge, and have their lower extremities attached to asleeve i-at opposite sides thereof, the sleeve forming :part of the hinges. Sleeve l is positioned so that-its axis is perpendicular to the pl'aneof the shank.

An arcuate brace rod t extends between the arms at their widest point of separation.

The holding member 2 comprises asheetmetal plate 9,.bounded on its bottom and sides by a U-shaped rod it, the endsof the-rod extending beyond the plate and being pointed, as at'l l ,-forming bottom-penetrating means. 'Rod 10 passes through sleeve 7 and forms the pintle of the hinge connection between the shank and holding member. "Plate 9 is notchedon its lcott'cin'i'edge to provide an opening to accommodate sleeve Land has its side edges perpendicular to the base. From the top of the side edges, the plate inclines downwardly'tow'ard the center, forming'tap'e'ring entering edges l 2exten'din'g irom the -points i l. The central portion of theleadin'gedge-is r'ecessed downwardly a majorfdistance int'o theplate, asat wardly and the recess extending to a point slow the bracerod 8-01" the shank. 'This r'eces's p E3, the Side edges of the recess converging {downits a greater arcof swing for the plate sothat tlie the arms 5 and s of-theshank, the recess idling-the arm 5 or'fi as the-pla'te swings, {Elie "to theinclineof the entering edges 'IZand 'th'etapering recess l3, plate 9 has-it's bottomeng'agingsiirfaces of gradually increasing width from the bottom penetrating edge to a point near the hinge end. As greater strains cause the holding member to penetrate farther into the bottom, greater surface is provided to withstand the greater strain.

Wings M are positioned at the lower corners of the holding member and extend inwardly diagonally of the plate 9. Wings 14 are wedgeshape, with the narrowest portion of the wedge projecting toward the leading edge of the holding member. These wings are arranged in pairs with a pair being positioned at each of the lower corners, the plane of the wings being perpendicular to the plane of the holding member and the wings of a pair extending from opposite sides of the holding member. This arrangement provides inclined edges l5 rising from the plane of the holding member, with the planes of the wings on a common side of the holding member diverging toward the trailing edge of the holding member.

In operation, the anchor'is dropped from the 3 boat or ship and falls downward through the water until it strikes bottom. The wings M in contacting the bottom will cause the anchor to fall on one side or the other with the shank hanging from the anchor cable, and the holding member swung downward about its pivotal connection with the shank until the points ll contact the bottom. If the bottom is soft mud or sand, wings III will embed themselves, and if the bottom is shale the wings will rest upon the bottom causing the holding member to assume an angle with points I I inclined downwardly. Movement of the boat will cause the anchor to drag along the bottom, and if the bottom is shale, the downwardly directed points I I will penetrate the bottom at an angle. If the bottom is soft and the wings are embedded, the dragging of the anchor will cause the wings to ride upwardly due to the cam-like edges l5 and the divergent positioning of the wings. As the wings lift the rear edge of the holding member, the forward edge with its points II will be inclined downwardly substantially as indicated in Figure 1. It will be noted that the angle of penetration is such that the fiat surface of the holding member plate 9 is presented to oppose the pull. It will also be noted that the greater the pull the deeper the penetration. Due to the tapering bifurcated shape of the leading portion of the holding member substantially increasing areas of the plate are presented to withstand the pull as penetration increases. This is in contradistinction to the principle of usual types of anchor.

In Figures 4 to 6 inclusive, a slightly modified form of anchor is shown. The sole difference between this form and that shown in Figures 1 to 3 is in the position and operation of the holding plate wings. As the structures are identical with the exception of the wings, the same reference characters have been used on identical parts;

In the modified form of the invention, the wings iii are substantially in the form of triangles with truncated base angles, the plane of the triangles being at right angles to the plane of the holding member, and the bases of the triangles being disposed outwardly. In this case the wings l6 are mounted on the base of the holding member and extend outwardly in the plane of the base.

This form of the invention operates a bit differently from the anchor shown in the first form. Wings I6 have no cam action, but do cause the holding member to assume a downwardly inclined position so that the points II will penetrate the 4 bottom. When this anchor strikes bottom, the wings will cause it to fall on its side as before, and the wings will then serve to retard the forward drag of the anchor, thus causing the holding member to tilt, forcing the points into bottompenetrating position. Thus it will be seen that in both instances the wings function to, first, cause the anchor to tilt on its side, and second, to force the holding member into an inclined bottom-penetrating position.

Although preferred and practical embodiments of the invention have been disclosed herein, it is to be understood that the invention may take other forms within the scope of the appended claims.

Having thus described my invention, what I claim is: v

1. In an anchor including a shank and bottomengaging member hingedly connected, said bottom-engaging member comprising a U-shaped frame having its base hinged to the shank and its upstanding arms parallel to each other and to the plane of the shank, and a filler of sheet metal between the arms of the U-frame from the open end of the U to the base, said filler being notched from its edge bridging the open end of the U-frame toward the base, the sides of said notch converging toward the base to form twin flukes tapering from points at the open end of the U-frame to substantial width near the base.

2. In an anchor as claimed in claim 1, fluketilting wings projecting perpendicularly from each side of each fluke, said wings emanating from the base corners of said U-frame.

3. In an anchor as claimed in claim 1, fluketilting wings projecting perpendicularly from each side of each fluke, and the planes of the wings of the two flukes converging toward each other from the base corners of the U-frame.
