BOAT ANCHOR Fii led Dec. 24, 1958 gwuwnio a Jams-EJ107121.

Patented June 4, 1940 UNITED STATES PATENT OFFICE (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein may be manufactured and used by or for the Government of the United States for governmental purposes without payment to me of any royalty thereon in accordance with the provisions of the act of April 30, 1928 (Ch. 406, 45 Stat. L. 467) This invention pertains to boat anchors. Objects of the invention are to provide a non-fouling, light-weight, simple, practicable and efficient, as well as economical boat anchor incorporating features whereby its compactness for stowing purposes make the same of particular desirability.

Other objects of the invention will be pointed out and become apparent in the following specification and accompanying drawing illustrating a practical embodiment of the invention and by which the same may be practiced.

Fig 1 of the drawing illustrates a perspective of an en: diment in an open and operable position, while L118 elevational view in Fig. 2 illustrates the same in closed position most suitable for stowage.

Broadly, my invention comprises an anchor, the shank of which consists of a pair of angular related beams positioned substantially in a common plane and arms extending therefrom adapted to support earth engaging flukes. The flukecarrying arms extend in substantially opposite directions from the beams, and are disposed in angular relation to the common plane of the beams.

In the embodiment of the invention illustrated the shank of the anchor comprises a pair of beams ill and H. These beams are coupled together at one end in a manner whereby the angular relation of one with respect to the other may be varied. To provide this adjustability the beams may be hingedly coupled or coupled, as shown, by a swivel bolt or pin l 2, which pin may also serve as a suitable means for the attachment of a clevis or ring to which the anchor rope may be secured.

In the embodiment shown, the shank beams HI and H are cross sectionally T-shaped and in the use of T-beams a number of advantages and desirable features are provided. Such beams possess a maximum or at least an adequate strength for the purpose, since the legs l4 and I5 of the Ts serve as reinforcements. Furthermore, beams of this design may be conventionally swiveled back to back, or in other words, with the head portions l6 and ll of the beams face to face, whereby in the angular adjustment of the beams the same act in a scissor-like manner; By this arrangement the overlapping fiat surfaces of the head portions It and I! of the beams support each other against torsional strain and displacement. Portions of .the legs M and i5 may be cut away as at E8 on the swiveled ends of the beams in order that a hole for the swivel pin l2 may be disposed centrally through the head portions I6 and l! of the beams, or on the axis of the legs Hi and i5. Portions of the heads l6 and I! may be cut away on the ends opposite their swiveled ends to provide shoulders 20 and 2| in- Wardly of the projecting

ends

22 and 23 of the leg portions I 4 and l 5 for purposes to be described hereinafter.

Means are provided to fix the beams iii and 'II in closed juxtaposition and opened at predetermined angles with respect to each other. These relative positions may be suitably maintained by the provision of ear-like members 24-45 and 2S-2'l, projecting reversely from the respective edges of the head portions I6 and l 'l of the beams I!) and H, which ears are provided with means for cooperatively securing the overlapping ears of the respective pairs in fixed predetermined positions. For this purpose one or more holes 28 are provided in the ears 24-25 and 2B-2'l 25 suitable to receive bolts or pins 29. These holes Ell are arranged in a manner whereby those through the ears 25-26 will coincide or register with each other when the beams are spread in the direction shown in Fig. 1. Likewise the holes 0 through the ears 24 and 2'! are arranged to register with each other should the beams be spread in the opposite direction. The holes 28 are also arranged in a manner whereby those through the ears 2 and 25 will register with those through 5 the

cars

28 and 27 when the beams are in, closed position as shown in Fig. 2.

The nukes 3i) and ti of the anchor are carried on

arms

32 and 33, which arms are hingedly or pivotally connected to the free ends of the beams 0 i9 and ii in a manner whereby they may be moved to predetermined opened positions in a direction angularly with respect to the plain through which the shank beams l!) and It may be moved. 5 The fluke arms may consist of square bar material, or any other suitable bars, worked and bent to shape. preferably with an elbow intermediate the ends to properly position the fiukes.

The top of the flukes may be, as shown, crowned to prevent fouling and are preferably shovel shaped or concave to increase their holding effects. They may also be sharpened and formed with a pointed pea to increase their digging effects. These fiukes are welded or otherwise secured to one end of the fluke arms with their peas foremost. The fluke arms may be connected to the free ends of the shank beams in any suitable manner which will afford angular adjustments of the arms with respect to the shank beams in a direction substantially normal to the plain through which the shank beams are angularly adjustable. A strength giving and strain relieving manner of adjustably connecting the arms to the shank beams is illustrated in the drawing wherein it will be seen that the ends of the fluke arms are slotted or bifurcated and straddle the

end portions

22 and 23 of the legs 14 and E5 of the shank beams. Holes are provided in the forked portions of the fiuke arms and in the projecting

leg portions

22 and 23 whereby bolts, pins or pivots. 34 and 35 may be passed therethrough to hingedly connect the arms to the beams. The holes through the forked portions of the fluke arms and the

projections

22 and 23 should be so arranged as to allow the ends of the forked portions to abut the shoulders 2t and 2i, formed by the cut back ends of the head portions 56 and l'l of the shank beams, serving as means for bracing the arms when in fully open position and also for limiting the opening of the arms beyond a most effective angle for the flukes.

To maintain the flukes in predetermined angular positions with respect to the shank beams, arm or lip portions 36 and 3'1, which may also be referred to as quadrant plates, may also be provided extending from the leg portions I 3 and 15 of the beams through the fork provided in the ends of the

fluke arms

32 and 33 and having stops 3% and 39 which prevent the fluke arms from being opened beyond a predetermined position. To retain the

arms

32 and 33 either in open position in abutment with the

stops

38 and 39, or in closed position whereby the peas of the fiukes rest against the leg portions it and i5 of the beams, the members 355 and 31 are provided with a series of openings through which pins or bolts 30 and ii may be passed.

The members 353 and 37 assist to relieve the fluke arms and the

pins

34 and 35 of the torsional strain by being passed through the crotch of the forked portions of the fluke arms.

In the construction of smaller anchors either the members 35 and 3'1 or the abutting features of the shoulders 25 and 2| may be omitted. Again in the smaller type of anchors it is within the scope of my invention to omit both of the features just described for preventing the fluke arms from opening beyond predetermined angles with respect to the shank beams and utilize any suitable tying or bracing members capable of sustaining the tension or compression tending to vary predetermined angles between the fluke arms and the shank beams. Such tying or bracing members may also be substituted for the ear-like members 2 i25 and 282? in the smaller type of anchors.

By this arrangement it will be seen that I provide an anchor which, when folded as shown in Fig. 2, is free of all projecting arms, prongs, etc., invariably causing entanglements with anchor ropes and provide an anchor which may be folded into a compact unit requiring very little storage space as compared with conventional anchors which are fixed in open position.

In preparing the closed anchor, as shown in Fig. 2, for launching, the pins or bolts 30 and M are withdrawn from behind the fluke arms, the arms opened into abutment with the stops, and the pins 46 and GI reinserted in front of the fluke arms to hold them open and in abutment with the stops. The pins 29 holding the shank arms in juxtaposition are then removed, the shank arms spread to predetermined positions, and the pins 29 passed through any coinciding holes 28 through the overlapping ears.

From the foregoing it will be seen that I provide an anchor with maximum holding properties and so designed as to normally fall clear with one of the fluke arms in position to dig in irrespective of which way the anchor may fall. The design of the anchor is also such that should the line foul in letting go the first strain will capsize and clear the anchor, bringing it into proper position. If the anchor lands as shown in Fig. 1 the fluke 3! is automatically in position for engagement with the earth and if the anchor should land in the reverse position the fluke 30 would be in the position in which the fluke 3| is now shown. Again, if the anchor should land with the fluke arm 32 horizontally with respect to the surface of the earth the overbalancing weight of the angularly disposed other arm 33 will cause the anchor to topple over into a position such as is shown in Fig. 1 whereby it will immediately dig in by its falling force, by its own weight or upon the least towing.
