Method and apparatus for raising and retrieving a boat anchor
US 3922990 A
Abstract
An anchor raising device includes a generally cylindrical watertight container having a closed bottom and a dished top. A square tube passes axially through the container to receive an anchor line and contains a locking pin to restrain the anchor line from descending once the anchor has been raised. When a boat anchor is to be raised, the device is put over the side, the engine is started and the boat is run upstream such that the anchor line is pulled through the tubing. The shape of the container causes it to remain substantially adjacent the surface of the water and in a substantially fixed position, thus to function as a pivot or pulley member about which the anchor line turns. The anchor is raised and the container has sufficient buoyancy to suspend the anchor for convenient retrieval.

N E R R U c T N E R R U C METHOD AND APPARATUS FOR RAISING AND RETRIEVING A BOAT ANCHOR BACKGROUND OF THE INVENTION This invention relates to a method of raising a boat anchor from a submerged anchoring position to a position on the surface of the water for convenient retrieval and to a novel device particularly adapted to perform the same.

It is a primary object of the present invention to provide a quick and easy method of raising boat anchors which can be readily performed without extraordinary skill and without the use of expensive or bulky equipment.

It is a further object of the present invention to provide a-device for use in the aforementioned method, which device is simple and easy to construct, durable in use and economical in cost.

Other objects and advantages will be apparent from the following description when read in conjunction with the accompanying drawings.

SUMMARY OF THE INVENTION My method of raising and retrieving a boat anchor comprises moving the boat from an initial position downstream of a surface point overlying the anchor to a second position upstream of such point while causing the anchor line to pivot over a buoyant, substantially stationary pivot member, the second position being determined by the position of the boat when the anchor is raised to a point immediately beneath the pivot member. The method further comprises restraining the anchor from descending beneath the pivot member, moving the boat toward the pivot member while drawing in the anchor line, and then retrieving the anchor.

The anchor raising device of the invention comprises a generally cylindrical watertight container having a closed bottom and a dished top. Tubular sleeve means are disposed generally axially within the container and extend through the container from the bottom to the top. The sleeve means are adapted to pass an anchor line. therethrough.

The container further comprises releasable anchor line restraining means disposed therewithin, the restraining means being adapted to restrain movement of the anchor line with respect to the sleeve means in the direction of the container bottom, yet being adapted to permit movement of the line with respect to the sleeve means in the direction of the container top.

Preferably the sleeve means comprises a length of square tubing which extends above the dished top. The releasable anchor line restraining means preferably comprises a diagonally extending slot disposed in each of two opposed walls of the tubing and a metal pin received in such slots, the slots being so positioned with respect to the tubing that the anchor line can pass between the pin and the tubing only when the pin is positioned at the top of the slots.

Preferably a nylon sleeve is received on the pin interiorly of the tubing. The nylon sleeve has an outer diameter greater than the width of the slots, whereby the sleeve is adapted to retain the pin within the slots.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, there is illustrated a boat 10 anchored in a conventional manner by an anchor 11 having its flukes l2 embedded at a submerged point 13, the anchor being connected to the boat by an anchor line 14. The boat 10 is shown situated on the surface of the water at a position 15 normally downstream of a surface point 16 overlying the submerged anchor 11, nonnally being carried to this point by the stream or tide within the limitations of the slack in the anchor line The anchor raising device 17 comprises a cylindrical watertight container 18 preferably made of aluminum or plastic and having a closed bottom 20 and a dished top 21. While the size of the container is directly related to the weight of the anchor to be raised, I have found that a container 12 inches in diameter and 18 inches long has sufficient buoyancy to overcome the weight of and operates satisfactorily to raise the usual small boat anchor 11.

A tubular sleeve 22 in the form of 1 /2 inch square aluminum tubing of one-eighth inch or three-sixteenths inch wall thickness is disposed axially of the container 18 and extends therethrough from the bottom 20 to a point 23 above the dished top 21, which point 23 is generally coextensive with the length of the container wall 24. The tubing extends through the bottom and the dished top and is welded thereto as shown.

The top 21 is preferably dished so as to be depressed approximately four inches at its center. I have found that if the top is dished approximately this amount in a container of the size hereinabove set forth, the device 17 will exert sufficient drag in the water to be retained at a substantially fixed position with respect thereto when the anchor line 14 is pulled through the sleeve 22, thus to permit the device to function as a fixed pulley or pivot member in a manner hereinafter to be described.

Anchor line restraining means are provided within the tubular sleeve 22 and such preferably take the form of a pair of diagonally extending five-sixteenths inch milled slots 25 disposed one in each of two opposed walls 26 of the tubing outwardly and above the dished top 21 as shown. A one-quarter inch diameter aluminum pin 27 provided with a three-eighths inch outer diameter sleeve 28 of nylon tubing is received in the slots 25, the nylon sleeve 28 terminating interiorly of the tubing thus to retain the pin 27 therewithin. The slots 25 are so positioned that the anchor line 14 can pass between the pin 27 and the wall 30 of the tubing only when the pin 27 is positioned at the top of the slots 25. In this manner the pin 27 and nylon sleeve 28 function to permit the anchor line 14 to be pulled through the sleeve 22 in the direction of the dished top 21, the friction of the line 14 holding the pin 27 at the top of the slots 25, but restrain the anchor line 14 from passing through the tubing when the line attempts to pass in the opposite direction, that is, in the direction of the container bottom 20, as, for example, would be the case were the anchor 11 to attempt to descend with respect to the device 17 once having been raised.

A handle member 31 connects the tubing wall 32 above the dished top 21 to the wall 24 of the container and is so positioned as to permit a boatman to grasp the device and, using his fingers, to retain the pin 27 adjacent the top of the slots 25, thus to permit the anchor 11 to descend and the line 14 to pass downwardly through the tubing 22 when it is desired to lower the anchor.

Operation When the boat desires to raise its anchor 11, the anchor line 14 having theretofore been passed through the tubular sleeve 22 (FIG. 4), the device 17 is put over the side (FIG. 5), the engine is started and the boat is run upstream. Water runs into the dished top 21 and pulls the container 18 slightly under the surafce, as, for example, between two and three feet under the surface, but otherwise the container tends to remain in place, that is, it remains substantially adjacent the surface and in a substantially enough fixed position so as to serve as a pivot or pulley member for the anchor line 14 (FIG. 6). The line is pulled through the tubing 22, raising the pin 27 to a position adjacent the upper ends of the slots 25, and as the boat is driven upstream of the submerged anchor 11, the anchor is gradually raised to a position adjacent the bottom of the container 18.

.As soon as the boat is stopped, the weight .of the anchor 11 tends to reverseits relative direction with respect to the container 18 and causes the nylon covered pin 27 to descend in the slots 25, acting as a brake and restraining further downward motion of the anchor 11 with respect to the container 18. Since the container has sufficient buoyancy to overcome the weight of the anchor, it floats on the surface, with the anchor hanging therebeneath (FIG. 7). The boat can then be moved toward the raised anchor, as by permitting the same to drift thereto, and the anchor retrieved (FIG. 8).

If the boatman desires to lower the anchor, he merely grasps the device by the handle member 31, lifts the pin 27 to a position adjacent the top of the slots 25, whereupon the weight of the anchor 11 causes the anchor line 14 to pass through the tubing 22, thereby permitting the anchor to descend.

While one embodiment of the invention has been shown and described, it is to be understood that modifications may be made without departing from the spirit and scope of the invention which is limited only by the following claims.
