ANCHOR Filed Dec. 8, 1958 BYPAUL F HAUT mM/0W@- 'ATTORNEYJ Patented May 14, 194e Um'ro stares ATET OFFCIEI` This invention relates to ships anchors.

An object of the invention is to provide a simple, practical and inexpensive type of anchor for ships andv the like.

Another object is 'to' provide an anchor as de scribed adapted to have improved holding properties and to be free from entangling the anchorI chain.

A further object is to provide an` anchor as described having increased strength as well as reduced weight.

Other Vobjects and advantages `will appear and` y be brought out more fully in the following specis ilcation, reference being had to the accompanying drawing, wherein Fig. 1 is a side View of an anchor embodying my invention shown in partially anchored posi tion.

n 2 is a similar view showing the anchor fully engaged with the sea bottom, and

Fig. 3 is a view of the anchor as viewed looking up from Fig. 2.

Referring more particularly to the drawing, I show an anchor having a shank 5 having a stock 6 and a pivoted shackle 1 for engagement with the anchorf chain 8. Stock 6 has the customary curved end. portion 9 and a terminal ball Iii and is further provided with a shoulder I l and a recess l2 fora tapered lock pin I3 suitably secured thereto as by a chain.

`Shank 5 is preferably of` forged steel `and formed with a web i4 for maximum strength with minimum weight. Shank 5f has bifurcated end n portions l5 between which a crown I5 is pivoted 'm at It, pivot Il being suitably secured by a washer i8 and a shackle pin i9.

Crown I6 is provided with a pair of fluke arms 2l] nearly at right angles thereto, andy flukes 2l are formed at the free end of` each fluke arm 20.

iiuke arms 20 and are each provided with a cut out portion 22 forming points 23 which are adapted to pass on either side of shank 5 as clearly shown in Fig. 2, the shank 5 being admitted into the cut out portion 22. Cut out portion 22 forms an abutment edge 24 adapted to engage a notch 25 in shank 5 whereby excessive strain on the fluke arms 2li may be` transmitted tothe shank 5` and relieve the strain from pivot Il. The 50 crown l and fluke arms 20 are providedl with a web portion 26 similar to web I4 for reduced weight and maximum strength and have` substantially sharp corners 21. 4 i y The operation of the invention should be ap- 55 parent from the foregoing description. The anchor when dropped will first assume the position indicated by the dotted lines in Fig. l and when pulled by the anchor chain 8, the lower corner 21 will pivot the crown to the full position shown 50 in Fig. 1, whereupon the points 23 which are Flukes 2l are preferrably formed integrally with curved outwardly will catch and dig into the sea bottom 28. `1i"urther pull on the chain 8 will cause the anchor to assume the position shown in Fig. 2 with the lower fluke, iiuke arm and crown firmly embedded in the sea bottom. Further tension on the chain and shank will cause the upper nuke arm 20 to be irmly pressed against shank `5 and retain the anchor in position, abutment `edge 24 being engagedin the upper notch 25 and serving to keep the shank 5 horizontal. I

Withthe anchor positioned as described `if the boat swings around, there will be no possibility of the anchor chain to foul the nukes because of there being no protruding parts, the points 23 being below the upper edge of shank 5.

The engagement of abutment edge 24- and notch 25 will reduce the strainy on. the shank 5 and reduce the likelihood of breaking the crown or the shank. The points 23 being on both sides of shank 5 will reduce the side strain on pivot il" and prevent twisting of the shank near the pivotl'l.

` Having described: my invention, what I claim is" l. An anchor as described having an elongated shank, a `crown pivoted at one end of said shank, said crown having a pair of uke arms substantially at right angles thereto, said flukes having terminal cut out portions forming points adapted to receive said shank therebetween, said flukes having an abutment at the base of said recess and said shank having notches adapted to ensaid abutments.

2. An anchor comprising an elongated shank of rectangular form, having a bifurcated outer end and notches in its opposite edges, a crown pivoted in said bifurcated end and having a nuke arm at each lend substantially at right angles thereto, said ilukes having rectangularr cut-cut portions of approximately the same cross area as that of the shank and the bottom walls of the cut-out portions forming dogs adapted to enter the notches, whereby the flukes straddle the `shank and lock in said notches to prevent twisting of the crown and rearward movement on the shank and relieve the pivot of considerable strain.

3. An anchor comprising an elongated shank having a bifurcated outer end formed at its inner end with converging walls, a crown pivoted in said bifurcated end and having a fluke arm at each end substantially at right angles thereto, said flukes having their outer ends cut out to allow the same to straddle the shank and closely engage the saine, whereby any material bending of the pivot of the crown is prevented by the engagement of the crown. with the converging walls of the bifurcated end of the shank.
