ANCHOR Filed Nov. 24, 1959 FIG! MAYN ARD C. BEVERS INVENTOR.

3,Z6,840 Patented Mar. 27, 1962 3,026,840 ANCHOR Maynard C. Bevers, Gladstone, reg., assignor to Revers Anchor, Inc., Portland, Oreg., a corporation of Oregon Filed Nov. 24, 1959, Ser. No. 855,091 2 Claims. (Cl. 114-208) This invention relates to an improved construction for an anchor, and more particularly to an anchor construction having an anchor body including a pair of laterally spaced flukes, and adapted to be connected to the usual anchor line by means of an anchor shank pivotally connected to the anchor body.

A general object of the invention is to provide an improved construction for such an anchor wherein provi- S101! is made for accommodating swinging movement of the anchor shank from an aligned position with the flukes to limit positions disposed on either side of this aligned position, and wherein the limit positions for the shank are defined by means engageable with the flukes.

Another general object is to provide an improved construction wherein the means limiting movement of the anchor shank accommodates substantially equal angular movement of the anchor shank to either side of an aligned position with the flukes.

A further object of the invention is to provide an improved construction wherein the flukes of an anchor are provided with means positioning them at an acute angle relative to a bottom with the anchor on the bottom, and provision is made for the usual anchor line connected to the shank of the anchor to pull on the anchor in a direction opposite to the one the flukes are pointing (as when removing the anchor) with the pull exerted at a location substantially coinciding with the rear ends of the flukes and with the anchor line substantially unencumbered by the means positioning the flukes at said acute angle.

A still further object of the invention is to provide an anchor with the features hereinabove described which is simple in construction, and capable of mass production at relatively small unit cost.

Other objects and advantages are attained by the invention, such being described hereinbelow in conjunction with the accompanying drawings, wherein:

FIG. 1 is a side elevation of an anchor constructed according to this invention;

FIG. 2 is an end view of the anchor illustrated in FIG. 1 showing in dashed and solid outlines various positions for the anchor shank;

FIG. 3 is a perspective view of the anchor; and

FIG. 4 illustrates the anchor as it rests on a river bottom and prior to pulling on an anchor line to effect removal thereof.

Referring now to the drawings, indicates generally the anchor of the invention, comprising an elongated shank portion 12 by means of which the anchor is attached through the usual anchor line to a vessel, and a pair of laterally spaced and oppositely disposed flukes, indicated at 14 and 16. These are flat, and occupy a common plane. The forward ends 14a, 16a of flukes 14, 16 are pointed, thus to enable them better to penetrate the usual bottom. The flukes are triangular in shape, and their inner edges converge to define a throat for the anchor indicated at 17. The substantially V-shaped throat is constructed to cradle a rock or other obstacle on a bottom, whereby the anchor may better be held from shifting.

Interconnecting flukes 14, 16 is a rod or bar portion 18. This is secured as by welding to the rear ends 14b, 16b of the flukes, and is parallel to the plane of the flukes. To the rear of the flukes and secured to the flukes through ends of bar 18 are plates 22, 24. Each plate is joined to an end of bar 18 at a location midway between the ends of the plate, so that it extends approximately equal distances to either side of the plane of the flukes. Plates 22, 24 occupy a common plane that is normal to the plane of the flukes. The plates constitute means for supporting the anchor so that when it rests on a bottom, the flukes extend at an acute angle upwardly from their forward ends. Each plate has a width substantially coextensive with the width of the rear end of the fluke directly in front of it.

An intermediate portion 18a of rod 18 spans the distance between the flukes and constitutes a spindle portion in the construction. Shank portion 12 is pivotally connected to the anchor by means of a sleeve 36 rotatably mounted on spindle portion 18a. The sleeve has a length slightly less than the distance between the flukes, and the flukes confine the sleeve from lateral movement on spindle portion 18a.

In the embodiment shown, shank portion 12 takes the form of an elongated U-shaped bar that has its ends Welded to sleeve 36. The space 38 between the legs of the bar constitutes an elongated runway extending along the length of the shank. An anchor line, such as the anchor chain indicated at 40 in FIG. 4, is connected to the shank by linking the last link of the chain through runway 38. The runway accommodates shifting of the end of the anchor line longitudinally of shank portion 12.

In the construction, stop means is provided inhibiting pivotal movement of the shank portion after the shank portion has moved substantially equal angular distances to either side of an aligned position with the flukes, as best shown in FIG. 2. This stop means comprises a bar 46 secured as by welding to shank 12, and having ends that extend over flukes 14, 16 and plates 22, 24. In one limit position for the shank, illustrated in solid outline in FIG. 3, the ends of bar 46 abut the inner faces of one set of ends of plates 22, 24, to prevent further movement in a clockwise direction. In the other limit position for the shank portion, indicated in dotted outline in FIG. 3, the ends of bar 46 engage one set of faces of flukes 14, 16 to prevent further movement in a counter-clockwise direction.

Since the flukes and the plates are at right angles, the shank portion is limited substantially to movement through a 45 angle. Bar 46 is positioned on shank portion 12 so that the angular movement of the shank to either side of an aligned position with the flukes is substantially the same. Thus the anchors operation is the same regardless upon which side it rests when on bottom. Pivoted movement of the shank relative to the flukes and plate 22, 24 is about an axis substantially coinciding with the intersection of the plane of the flukes with the plane of plates 22, 24, since bar portion 18 is disposed in the plane of the flukes and immediately adjacent the plane of plates 22, 24.

In operation, the flukes and plates 22, 24 of the anchor may assume the position illustrated in FIG. 4 with the forward ends 14a, 16a of the flukes engaging a bottom and with one set of ends of plate portions 22, 24 resting on the bottom thus to raise end 14b, 16b of the flukes whereby the flukes angle into the bottom. When it is desired to remove the anchor by pulling the anchor rearwardly (or in a direction away from the pointed ends of the flukes), anchor line 40 is pulled toward the rear of the anchor, which pivots the shank in a clockwise direction about bar 18 until bar 46 strikes the inner faces of plates 22, 24. Continued pull on the anchor line, in the direction of the arrow in FIG. 4, will then pull ends 14a, 16a from the bottom. Since the connection of the shank with the flukes is by means of a bar 18 located at the rear ends and substantially in the plane of the flukes, the pull of the anchor line on the anchor is exerted at a location substantially coinciding with the location of the fluke rear ends. The spacing between plates 22, 24 enables the anchor line to drop between the plates, and minimizes any tendency of the anchor line to twist or turn the anchor during its removal.

It is claimed and desired to secure by Letters Patent:

1. In an anchor comprising a pair of laterally spaced and oppositely disposed substantially flat fiukes disposed in a common plane and having forward ends adapted to engage a bottom, and a plate for each fluke joined midway between its ends with the rear end of the fluke and extending normally to either side of the plane of the flukes, said plates occupying substantially a common plane, the improvement comprising a connecting bar interconnecting the two flukes and disposed adjacent and substantially parallel with the plane of the flukes and the plane of the plates, a sleeve journaled on a portion of said connecting bar intermediate the flukes having a length coextensive with the spacing between the flukes, an elongated anchor shank joined at one end to said spindle portion, and a stop bar integral with the anchor shank and spindle portion for limiting movement of the anchor shank relative to the fiukes, said stop bar having a portion extending over at least one of the flukes and the plate joined thereto, said stop bar limiting movement of the anchor shank in one direction by striking said one of the flukes and limiting movement of the anchor shank in the opposite direction by striking the plate joined to said one fluke.

2. The anchor of claim 1 wherein the anchor shank has an elongated runway extending along the length thereof adapted to be connected to an anchor line.
