Fisher; and one-eighth to Lowell L. Heinke Filed Feb. 13, 1959, Ser. No. 793,110 11 Claims. (Cl. 114-208) This invention pertains to marine anchors and more particularly to anchors which are most ideally suited for use with small craft.

In anchoring a marine vessel, securing the anchor to the bottom of a body of water is frequently a problem. Once the anchor is secured an even more diiiicult problem is encountered in that it is often extremely ditlicult to raise the anchor. At times the anchor becomes so securely embedded in the bottom as to make hoisting of it extremely difiicult. With small boats where hoisting is accomplished by a man pulling on the anchor line, raising of the anchor is at times practically impossible without resorting to such extremes as diving for it.

One proposal which sought to overcome these diificulties provided an anchor in which the arms were pivotally mounted on the shank and in which a relatively strong spring held the arms in an anchoring position. When the boat operator wished to raise such an anchor he would accelerate his boat in a direction away from the anchor causing the arm embedded in the bottom of the body of water to shift relative to the shank against the action of the spring. Once the arm had passed over center and the spring had passed its maximum distention, the arm swung to a rather reverse position which facilitated pulling the arm and a fluke at the end of the arm from the bottom. The difliculty with this proposal has been that if a spring is provided which is strong enough to hold the boat firmly in high winds, or the like, the boat may not have the power to overcome the spring when the boat operator seeks to raise the anchor. This can and has resulted in small boats swamping. Further such an anchor was of no value whatsoever with sailing craft which, even if equipped with auxiliary power, could not overcome such a spring. Further, because of limited mobility, a sailing vessel has the greatest need for a dependable releasable anchor.

The present invention provides an anchor which can always be released from the bottom of a body of water. The release can be accomplished from the boat. This invention also provides an anchor which will positively hold a vessel in an anchored position, and which anchor will not accidentally shift to the hoisting position.

Accordingly, the principal object of this invention is to provide a novel and improved anchor which can easily be released from the bottom of a body of water at the will of the operator and which at the same time will dependably anchor a vessel.

Another object of the invention is to provide a novel and improved anchor which can, at the election of the operator, be released either through standard techniques or through the utilization of a novel and improved releasing mechanism.

A related object of the invention is to provide a novel and improved anchor which is equipped with a releasing mechanism which is actuated by contact with an operator controlled releasing means.

A related object of the invention is to provide a novel and improved anchor having a releasing trigger and a triggering device in the form of a ring slidable along the anchor line.

A further object of the invention is to provide a novel and improved anchor which has an anchoring position,

3,059,607 Patented Oct. 23, 1962 a release position, a lock to hold it in the anchoring position, operator control means to contact and release the lock, and in which the relative position of the anchor line and the anchor fluke when in the anchoring position is the opposite of the released position.

A more specific object of the invention is to provide a novel and improved anchor which has a plurality of arms pivotally carried by a shank, and a lock bar which holds the arms and the shank in a fixed relative position for anchoring.

A related specific object of the invention is to provide an anchor made in accordance with the foregoing object in which a sleeve is slidably carried by the shank and operably connectable to both the lock bar and the pivot arms.

An alternate specific object of the invention is to provide a novel and improved anchor in which the line is connected to the crown end of the shank by a tong, and in which a slack auxiliary line is connected to the crown of the anchor in order that upon release of the tong further tensioning of the line will pull the anchor in a reverse direction.

Other objects and a fuller understanding of the invention may be had by refer-ring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

FIGURE 1 is a fragmentary partially sectioned view of one of the novel and improved anchors in the preferred form;

FIGURE 2 is a side elevational view of one of the novel and improved anchors in an alternate form On a reduced scale with respect to FIGURE 1;

FIGURE 3 is a side elevational view of a novel and improved split ring used as the operator control actuation means and shown on an enlarged scale with respect to FIGURE 1;

FIGURES 4 and 5 are sequential views of yet another embodiment of the invention showing the release of the anchor from the bottom of a body of water; and,

FIGURE 6 is a fragmentary top plan View on an enlarged scale of the embodiment of FIGURES 4 and 5 in the released position.

In the drawings a shank is designated by 10 in each of the figures. The shank 10 has a ring end 11 and a crown end 12. A plurality of arms 13 are connected to the shank 10 at the crown end 12. Each of the arms 13 has a fluke 14 at its outer end. An anchor line 16 is connected to the ring end 11.

The previously described parts find an equivalent in both name and function in any prior art anchor. In each of the drawings an anchor of the grappling type which has four arms is disclosed. Analysis of the invention will show that it may be app-lied to an anchor with any number of arms. For example, the invention is equally applicable to a Danforth type anchor having, for all practical purposes, one arm, or the Northill type anchor which has-a pair of foldable arms, or a stock anchor. Thus, the invention is equally applicable to an anchor with any number of arms.

In FIGURE 1 a plurality of pivots 20 are provided at the crown end 12. Each of the arms 13 is pivotally carried by one of the pivots 20. Each of the arms 13 has an arm extension 21 which lies against a stop 22 formed on the shank -10 when the arms are in the disclosed anchoring position. Each of the arm extensions or projections 21 has a reduced diameter end portion 23 which extends under a sleeve 25.

The sleeve 25 is slidably carried on the shank 10. The sleeve 25 is held in the anchoring position by a lock bar 26. The lock bar 26 is connected to the shank 10 by a pivot pin 27. The lock bar 26 is held in the anchoring position by a spring 28 which is interposed between the 3 lock bar and the shank 10. A stop guard 29 may be fixed to the shank ll) to serve as a stop and thereby prevent accidental depression of the lock bar 26.

In FIGURE 3 a split ring 30 is disclosed. The split ring 30 has a hinge pin 31 to permit relative opening of

sections

32, 33. A suitable means is provided to lock the

sections

32, 33 together. This means may take the form of a leaf spring 34 which projects into a notch 35 to hold the sections together.

The split ring 30 may be positioned around the anchor line and dropped down it. The split ring 30 slides over the shank and a release portion 36 of the lock bar 26. The release portion 36 has an outer camming surface 37 which the ring 30 acts against. As the ring 30 travels from the ring end of the anchor toward the crown end 12 it will depress the release portion 36 and shift the lock bar 26, against the action of the spring 28, to the position shown in phantom in FIGURE 1.

Once the lock bar 26 is released, further tensioning on the anchor line will cause carnming surfaces 38 on the extensions 21 to shift the sleeve 25 to the position shown in phantom. This permits the arms 13 to move to a release position as will be described in more detail. If desired, a light spring may be used to aid in shifting the sleeve 25 to the release position.

In FIGURE 2 an alternate form of release mechanism in shown. There, a crown end ring 40 is added to a standard four arm or grappling type anchor. A releasable tong 41 has an eye 42 which is removably connected to the ring end 11. The tong 41 has first and

second lever members

43, 44 held together by a pivot pin 45. The lever members each have portions which define half of the eye 42 and

arm portions

46, 47 respectively. The arm portion 46 corresponds in purpose and function to the lock bar release portion 36. The arm portion 47 has an end eye 43 to which a main line extension 49 of the anchor line 16 is connected. A slack auxiliary line 50 is provided to connect the anchor line 16 to the crown end ring 41).

The

lever members

43, 44 are urged into a normally closed position by a light spring 51. The spring 51 urges the lever members together along a parting line 52 in the eye 42. It should be noted that inner surfaces 53 adjacent the parting line 52 are relatively flat and transverse to the shank 19 when connected to the anchor. These flat surfaces prevent accidental opening of the tong from tensioning of the anchor line, as might occur if the surfaces 53 were not substantially normal to the axis of the shank 10.

Release of the tong 41 from the ring end 11 is accomplished through essentially the same technique as is employed in releasing the anchor of FIGURE 1. The ring 30 is passed down the line 16 to shift the

lever members

43, 44 together against the action of the spring 51. This releases the tong from the ring end 11. Further tensioning of the anchor line 16 will be transmitted to the crown end ring 40 by the auxiliary line 50 causing the anchor to be hoisted in a reverse direction.

In FIGURES 4 through 6 an alternate form of anchor is shown and the sequential steps of release of any of the embodiment of this invention are better explained and shown. In the embodiment of these figures one of a plurality of links 55 is pivotally connected to each of the arms 13 and to the sleeve 25. The lock bar 26' has a pivotal connection 56 formed at the end of the release portion 36' nearest the ring end 11. A substantial portion of the lock bar 26 is disposed within a hollow shank 10. The spring 28 is also disposed within the shank.

The lock bar 26' has an actuating end portion 57 which extends through the sleeve 25'. When the anchor is in the anchoring position of FIGURE 4, an end hook 58 engages the sleeve and holds it in the anchoring position. In this anchoring position of FIGURE 4, the sleeve 25' is held away from the crown end 12 in a position in its path of travel which is toward the ring end 11.

When any anchor is embedded in the bottom of a body of Water the shank will normally lie in an essentially horizontal plane with at least one of its fiukes and usually at least a part of the associated arm embedded in the bottom. A substantial amount of line, or scope, is played out so that the anchor can assume this position with the shank essentially parallel to the bottom.

Normally, with any of the well known anchors, hoisting is accomplished by pulling in the anchor line and, if possible, shifting the boat, or other vessel to a position substantially over the anchor. This will tend to shift the anchor to a position somewhat approximating the position shown in FIGURE 4 where the bottom of a body of water is designated by the numeral 60.

If the seaman cannot hoist his anchor by pulling directly upwardly on the line, he will continue to move the vessel past the anchor to pull it in a reverse direction. This action will normally, but not always, release the anchor. Further, it is not always possible to shift the boat over the anchor and past it. For example, one common practice in anchoring small boats off a shore is to position one anchor near the shore line and another a substantial distance out in the water to hold the boat in a position where its fore and aft line is substantially normal to the shoreline. Under such conditions it is not possible to pass the boat over the anchor.

The outstanding advantage of this invention is that it permits the seaman to hoist his anchor under any adverse conditions. At the same time, once it is properly set, the anchor will not accidently become released from the bottom.

A new procedure is followed in weighing anchor with any of the embodiments shown, or the other equivalents, which will be apparent to one skilled in the art. The procedure, which is the same for all embodiments, will be described in detail in connection with the sequential view shown in FIGURES 4 through 6.

First the seaman tensions the anchor line 16 and moves his boat toward the anchor as much as possible. This hoists the shank 10 to as near the vertical position as conditions will permit. The seaman then places the ring 39 about the line 16. To trigger the mechanism and release the anchor the seaman simply allows the ring 30 to slide down the line 16, or alternately triggers any suitable operator controlled release mechanism.

As the ring 30 passes onto the shank 10 in the position of FIGURE 4 and further downwardly, the weight of the ring will carry it down until it coacts with the camming surfaces 37' and compresses, in the case of FIGURES 4 through 6, the lock bar 26. This compresses the spring 28 until the lock bar 26' is in the position of FIGURE 5. Movement of the lock bar 26' to the release position of FIGURE 5 permits the sleeve to shift to the release position and the arms 13 to pivot to the release position shown in FIGURES 5 and 6. The anchor may then be facilely withdrawn from the bottom. In the embodiment of FIGURES 5 and 6 a stop projection 59 limits the travel of the ring 30. If difliculty is encountered in moving the ring 30 against the stop 59, or its equivalent, the stop guard 29 of FIGURE 1 and the unnumbered stop of FIGURE 2 on the lever arm 43, the difficulty can be overcome by jiggling the anchor line. The jiggling action permits slack to appear in the anchor line while the anchor shank '10 remains in essentially a vertical position. This releases the tension on the engaged parts and permits the weight of the ring to trigger the release mechanism.

It will be seen that in each of the embodiments the relative positions of the flukes and the line when in the anchoring positions are the same with respect to the crown end 12. By this it is meant that when the anchor is in the anchoring position, the flukes 14 and the line 16 are on the same side of a plane which passes through the crown end 12 and is normal to the axis of the shank 10. Expressed another way, the flukes and the line extend in generally parallel directions. When the release mechanism is actuated one of these members, the fiukes 14 or the line 16, is shifted to the opposite side of such a plane so that the flukes and the line then project in opposite directions with respect to the shank.

Thus, in the anchoring position the line is pulling the arms 13 and the flukes 14 toward the vessel with the flukes nearer the vessel than the remainder of the arms. Tensioning of the line, when there is adequate scope, pulls at least one of the flukes into the bottom. When the release mechanism is actuated, the converse is true and the flukes are then further from the vessel than the remainder of the arm 13. Tensioning of the line then pulls the flukes from the bottom.

While the invention has been described with a great deal of detail, it is believed that it essentially comprises a novel and improved anchor having releasable means for holding the line and flukes in anchoring positions until released by engaging actuation of an operator controlled releasing means.

Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention as hereinafter claimed.
