G/LBERTSON GEORGE R. MA/DL BY l fi W W United States Patent 3,285,218 ANCHOR Marvin L. Gilbertson, 1709 3rd Ave. S., and George R. Maid], 830 Adams St., both of Anoka, Minn. Filed Apr. 13, 1965, Ser. No. 447,790 4 Claims. (Cl. 114-207) This invention pertains to an anchor for boats and the like and more specifically to a small lightweight anchor in which the earth engaging fingers are stored within the shank while not in use.
In the field of anchors for small boats and the like a variety of sizes and shapes of objects which may be utilized as anchors have been developed. In all cases these prior art anchors are either extremely heavy and cumbersome or the portion thereof which engages the earth to provide the anchoring action protrudes at all times and becomes a hazard to the boat and its occupants during nonuse.
In the present invention a shank is provided having a hole or other means at one end thereof for attaching a rope or the like thereto. The other end of the shank has a cap or locking member threaded thereon. A pair of metal rods having a rectangular shaped cross section have mating grooves approximately centrally located therein so that the arms fit together, perpendicular to each other, in a cross. It should be understood, however, that more than two arms could be utilized in this invention and the present embodiment includes only a pair for simplicity of description.
The threaded end of the shank or body of the anchor has a plurality of openings therethrough which are approximately equally spaced radially about the circumference and which may be simply slots cut longitudinally into the shank along diameters thereof. The arms, which are fitted together so that the ends radiate spoke-like from a central axis, are fitted into the openings and held in place by the cap which is then threaded onto the end of the shank. Each of the arms is constructed so that the wider dimension of the rectangular shaped cross section is positioned parallel to the longitudinal axis of the shank in the intermediate portions thereof and the ends are twisted so that the wider dimension is perpendicular to the axis of the shank, or in a horizontal position when the anchor is upright. In this manner the arms are provided with a greater degree of mechanical strength while the ends are shovel-like to add a greater degree of holding power.
The shank or body of the anchor is hollow in the present embodiment so that the arms may be conveniently stored therein during nonuse. Thus, during nonuse the anchor forms a convenient lightweight, pipe-sized package with no dangerous projections extending therefrom. When ready for use the anchor is quickly and easily assembled into a handy lightweight anchor having a plurality of earth engaging fingers extending therefrom for maintaining a boat or the like at any desired position.
It is an object of the present invention to provide an improved anchor for boats or the like.
It is a further object of the present invention to provide an improved anchor which is lightweight and easy to use.
It is a further object of the present invention to provide an anchor which is easily disassembled and stored with no dangerous projections extending therefrom.
These and other objects of this invention will become apparent to those skilled in the art upon consideration of the accompanying specification, claims, and drawings.
Referring to the drawings wherein like characters indicate like parts throughout the figures:
FIG. 1 is a view in perspective of the anchor in stored position;
3,285,218 Patented Nov. 15, 1966 FIG. 2 is an exploded elevational view, slightly reduced in size, of the anchor in FIG. 1, portions thereof broken away and shown in section;
FIG. 3 is a perspective view of the anchor in the assembled position;
FIG. 4 is an exploded fragmentary view of the anchor in perspective illustrating the assembly thereof;
FIG. 5 is a sectional view as seen from the line 5-5 in FIG. 3;
FIG. 6 is an elevational view of a modified anchor in the stored position, parts thereof broken away and shown in section;
FIG. 7 is a view in perspective of the modified anchor in the assembled position;
FIG. 8 is a sectional view of the modified anchor as seen from the line 88 in FIG. 7; and
FIG. 9 is a view of the anchor in use.
In FIG. 1. the body or the shank of the anchor is designated numeral 10. The right end is permanently closed by flattening a portion 11 thereof. It should be understood that the right end of the shank 10 might be closed in a variety of ways Well known to those skilled in the art but the present method is utilized in this embodiment for simplicity. A hole 12 is drilled in the flat portion 11 to provide for the connecting of a rope or the like to the anchor. The left end of the shank 10 is threaded and a cap 13 is engaged therewith. The cap '13 may be knurled or may have some other design thereon which will facilitate gripping for easy engaging and disengaging of the cap 13 with the shank 10.
A pair of arms 15 and 16 are formed from metal rods having a rectangular shaped cross section, which in this embodiment has one dimension substantially longer than the other. When the arms 15 and 16 are in a generally horizontal position an intermediate portion 17 and 18 of each respectively is positioned with the long dimension of the cross section substantially vertical and each of the ends 19 of the arms 15 and 16 are twisted with respect to the intermediate portions 17 and 18 so that the long dimension of the cross section is positioned horizontal.
An upper and a lower groove 20 and 21 are formed approximately centrally in each of the arms 15 and 16 and extend horizontally across the arms 15 and 16 perpendicular to the longitudinal axis thereof. The grooves 20 and 21 are substantially rectangular'shaped and have a width approximately equal to the narrow dimension of the cross section of either of the arms 15 or 16. Thus, by positioning the arm 16 perpendicular to the arm 15 and vertically above it the lower groove 21 of the arm 16 fits into the upper groove 20 of the arm 15 to form a cross in which the ends 19 of the arms 15 and 16 radiate spoke-like from a central axis perpendicular thereto. The grooves 20 and 21 interlock in this position and substantially prevent horizontal movement of either of the arms relative to the other arm. It should be noted that since there is an upper groove 20 and a lower groove 21 in each of the arms 15 and 16 they could also be fitted together with the arm 15 vertically above the arm 16. Also, in the event that more than two arms are to be utilized in an anchor the grooves 20 and 21 would be cut at an angle other than 90 With the longitudinal axis of each of the arms, which angle would depend upon the number of arms being utilized.
The shank 10 has four rectangular shaped openings 25- 28 adjacent the threaded end thereof. In the present embodiment the openings 25-28 extend from the end of the shank 10 longitudinally along the shank 10 and are equally spaced radially about the circumference thereof. Openings 25 and 27 are opposite each other on the circumference and have an approximately equal depth while openings 26 and 28 areopposite each other on the circumference and have an equal depth but slightly greater than the depth of the openings 25 and 27. The openings 25-28 are positioned so that- thecrossed arms 15 and 16* slide easily therein with the upper arm 16 in the openings 26 and 28 while the lower arm 15 is in the openings 25 and 27. Once the arms 15 and 16 are positioned in the openings 25-28 as explained the cap 13 is engaged with the threaded end of the shank and butts against the lower arm 15 to maintain the entire assembly securely in position. It should be noted that in the event more than two arms are utilized in an anchor two extra openings for each extra arm would have to be cut in the end of the shank 10 and all of the openings would have to be equally spaced radially about the circumference of the shank 10. Thus, the ends 19 of the arms 15 and 16 radiate spokelike from the threaded end of the shank 10 to form earth engaging fingers.
The intermediate portions 17 and 18 of the arms 15 and 16 have the longest dimension of the cross section lying parallel with the longitudinal axis of the shank 10' so that the arms 15 and 16 have the greatest strength along axes parallel to the longitudinal axis of the shank 10, which is in general the direction of forces produced on an anchor. Also, the ends 19 of the arms 15 and 16 are twisted 90 so that the longest dimension of the cross section is perpendicular to the longitudinal axis of the shank 10 and, thus, the ends 19 of the arms 15 and 16 are shovel-like to add to the holding ability of the anchor. In addition to these structural features the shank 10 of the anchor is hollow and has a suflicient length to receive the arms 15 and 16 therein for storage purposes. In the event that it is preferred to have a solid shank 10*, the arms 15' and 16 are each provided with a hole 30 in one end thereof so that the entire assembly may be dismantled and conveniently connected together for storage by a wire or the like to prevent loss of any of the components. Also, one of the arms 15 or 16 may be attached to a string by the hole 30 and utilized as a depth gauge. Further, the locking member or cap 13 may take the form of a locking sleeve, not shown, which may be threadedly received on the other end of the shank 10 so as to securely lock the arms 15 and 16in operative position.
In FIGS. 6-8 wherein like parts are indicated with like numerals with prime marks added a modified embodiment of an anchor is illustrated which is similar to the previously described embodiment except the shank 10' and the cap 13' are composed of some material other than metal, such as plastic or the like. The cap 13" has a slightly different design thereon for gripping purposes since a knurled effect is very diflicult to obtain in plastic and has a tendency to wear off very quickly. 'The shank 10 has a collar 35 imediately above the threaded portion thereof to add strength thereto. The collar 35 extends radially outwardly from the shank 10' and extends longitudinally along the shaft a substantial distance so that the cross sectional area of the shank 10' is substantially increased immediately above t-he arms 15' and 16, where the forces on the shank 10" would be the greatest.
A cylindrical piece of heavy material 36 such as lead or the like is contained within the hollow shank 10' at the closed end 11' thereof by means of a pin 37 passing shank 10 makes the assembled anchor top-heavy which causes the shank 10' to fall into a substantially horizontal position rather than maintaining a vertical position when w 1 the assembled anchor is dropped from a small boat or the like.
Thus, an anchor has been described which is lightweight and easy to handle and which has good earth gripping qualities when in the assembled position. Also, the anchor may be quickly and easily disassembled and presents a pipe-like package in the stored condition. Because the earth engaging fingers are disassembled from the shank and stored therein the anchor is extremely safe to boat and occupant alike in the stored condition.
While we have shown and described a specific embodiment of this invention further modifications and improvements will occur to those skilled in the art. We desire it to be understood, therefore, that this invention is not limited to the particular form shown and we intend in the appended claims to cover all modifications which do not depart from the spirit and scope of this invention.
