United States Patent 3,279,413 BOAT ANCHOR HOIST Robert Ellis, Solana Beach, Calif., assignor to Robert E. Peterson, Downey, Calif. Filed Jan. 7, 1965, Ser. No. 424,024 13 Claims. (Cl. 114-210) This application is an improvement over my prior application Serial No. 397,192.

This invention relates to boat anchor hoists and the principal object of the invention is the provision of means for keeping the deck of the boat clear of the usual anchor and attached rope by hauling the anchor and rope below deck, all with a single manipulation of the anchor rope from any prescribed location on the boat.

Other and further objects will appear in the specifications and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention in which;

FIG. 1 is a top view of the mechanism while the anchor is being cast out or hauled in.

FIG. 2 is a longitudinal section of FIG. 1 on the line 22 thereof.

FIG. 3 is an isometric diagram of the integral extending arms and rotatable shaft.

Referring to the drawings in which like characters and numerals of refence refer to similar parts throughout the several views, the numeral 7 denotes the bow of the

boat

6 and 8 is the deck thereof. A pilot house 9 may or may not be included on the boat, a combined steering wheel and reel 10, such as described in my Patent #3,068,828, being preferably located therein. A short transverse shaft 12 is located at the bow of the boat below deck 8, this shaft being rotatably mounted between bearings 11, comprising two ang-les as illustrated. Welded at right angles to shaft 12 is the vertically disposed pulley arm 15 and at right angles to pulley arm 15 is welded the horizontal forwardly disposed anchor :arm 14, this anchor arm 14 being preferably slightly longer than pulley arm 15, with the anchor arm extending a short distance, slightly more than half the width of the circular anchor fluke 24, beyond the tip of the how 7 of the boat 6. At the overhanging end of arm 14 is the elongated hole 21, which hole not only permits passage of anchor rope 23 therethrough but also the anchor shank 22 up to the hilt of circular fluke 24 of the anchor. A rope pulley 25 is rotatably mounted to the extending end of pulley arm 15 by means of shaft 13 as shown. It is thus apparent that the shaft 12, pulley arm 15, anchor arm 14, pulley 25 and pulley 40, all rotate together at all times as an integral part, this being better illustrated by the isometric diagram in FIGURE 3.

When in its upright position, pulley arm 15 extends vertically through the forward part of door opening 26 in deck 8, as better illustrated in FIG. 2, a suitable door 37, hinged at its rear side 28, closes this opening automatically when the anchor is pulled below deck 8 and opens it automatically when the anchor is cast out. A flat spring 38, attached to the underside of door 37 assists in accomplishing this action as indicated by the curved dotted lines. The open door is shown leaning by gravity. against the pilot house but it is apparent that various known fittings may be used to hold the door in secure open position until the incoming anchor causes it to close. A fixed rope pulley 27 is rotatably mounted to that part of the boat 6, below deck 8, where it is desired to have the tip of the anchor shank 22 rest when the anchor is hauled into the boat. A pulley 40 is also secured to rotatable shaft 12, one end of the wire rope 41 being attached to the circumferential edge of pulley 40 at 42 while the other end of rope 41 is attached to helical spring 43 at 44, the other end of helical spring 43 being attached to loop 45 attached to any convenient place inside of boat 6. A pin depends from anchor arm 14, this pin automatically fitting into socket '61, which is sunk into the tip of the bow 7 of the boat, when the anchor is cast, thus preventing side strain on the arm 14 due to yawing of the anchored boat due to wind and waves. It will be particularly noted that horizontally extending anchor arm 14 is welded to pulley arm 15 above deck 8 while in anchor casting position, thus creating an offset around shaft 12 and causing the arm 14 to swing below the deck 8 at a half revolution of shaft 12 in the direction of arrow as indicated by the dotted lines.

The operation of this anchor mechanism is as follows: the full lines in the illustrations indicate the anchor in the process of manipulation either during casting out or hauling in while the dotted lines show the anchor and mechanism stowed under the deck with the door 26 in closed position overhead and the deck 8 completely clear of the customary cluttering up of the anchor and anchor ropes, leaving the deck for the unobstructed use of passengers or work of any kind. As here indicated, the rope 23 is being pulled in the direction of arrow 34 onto the reel 10 in pilot house 9. The tip of anchor shank 22 has already arrived at the outer tip of projecting anchor arm 14 and the shank 22 of the anchor is about to enter elongated hole 21, following rope 23 and beads 46 and to be pulled into position indicated by dotted lines 24B, the elongated hole 21 permitting some angular positioning of shank 22, the slight tension still existing in helical spring 43 tending to keep anchor arm 14 in horizontal position until the circular anchor fluke 24 contacts the end of anchor arm 14, whereupon the anchor arm is caused to describe the circular arc 50. Towards the end of its travel, the edge of the circular fluke 24 will contact the protruding upper end of flat spring 38 attached to underside of door 37, the anchor now being illustrated at position shown by dotted lines 24C. The flat spring 38 will bend downward slightly as shown by dotted lines and yet be sufliciently rigid to cause the cover 37 to tip forward and descend, and cover opening 26 as indicated by dotted lines and the are 51. The anchor has thus been pulled completely into and through hole 26 and now occupies the upside-down position indicated by dotted lines 24D, the fluke resting in an upside-down position at the end of horizontally disposed anchor :arm 14 while pulley arm 15 is in a vertical position extending downwards from slot 12 as shown. This action has taken place under continuously increasing tension of helical spring 43, due to the partial revolution of wire rope pulley 40. However, due to the pawl 32 contacting ratchet teeth 31, attached to reel 10, the anchor remains in place Without further pull on rope 23.

In order to cast the anchor into the water, the reverse motion takes place, the operator merely lifting the pawl 32 from teeth 31 thus causing the tension of spring 43 to rotate shaft 12 one-half revolution, lifting the anchor through are 50, the circular edge of the anchor fluke 24 contacting underside flat spring 38 during this process and first opening door 37 into position shown, before dropping into the water, the pulley 25 also contacting rope 23, and finally assuming position shown by full lines, the rope 23 also unwinding from reel 10 as required.

It will be apparent that, in order to accomplish the foregoing operation successfully, all the components, such as the hollow anchor shank, which enables the anchor rope to be secured to the anchor therein, the rounded tip of the anchor shank 22, the beads 46, the

integral quadrant arms

14 and 15, the offset arm 14 in relation to the below deck transverse shaft 12, and the manipulation of the cover 37 by anchor fluke 24, all combine to create the practical operation of this mechanism.

While I have illustrated the anchor rope 23 being manually wound upon a reel, it will be understood that an electric motor and controls may be used such as illustrated in my previous patent application, Serial #397,192, in FIG. 8, or the end of the mp 23 may be simply wound around a clea-t against the tension of helical spring 43 and tied, the loosening of this rope therefrom causing the anchor to be cast into the water as previously described, the door 37 being simultaneously manipulated automatically.

From the foregoing description it will be apparent that I have evolved a boat anchor and manipulating means therefor which will operate automatically by merely pushing a button or turning a wheel or loosening a rope, leaving the deck free and clear of the usual anchor and anchor ropesand enabling the deck to be used for the enjoyment of passengers or to more effectively do work thereon as well as to eliminate the individual labor of handling the anchor.

Various changes may be made in the embodiment of the invention hereinabove specifically described without departing from or sacrificing the advantages of the invention as defined in the claims appended hereto.
