BOAT ANCHORS AND MEANS FOR MANIPULATING SAME Filed Sept. 17, 1964 2 Sheets-Sheet l N44" NA.

United States Patent 3,261,319 BOAT ANCHORS AND MEANS FOR MANIPULATING SAME Robert Ellis, Solana Beach, Calif., assignor to Robert E. Peterson, Downey, Calif. Filed Sept. 17, 1964, Ser. No. 397,192 14 Claims. (Cl. 114210) This invention relates to boat anchors and means for manipulating same and the principal object of the invention is the provision of a boat anchor and operating means in which the anchor may be either cast out into the water or hauled into the boat from any prescribed location on the boat instead of the heretofore necessity of personally going to the bow of the boat and manually performing these arduous operations.

Another object of the invention is the provision of means for locating the mechanism used for this operation directly in the center of and at the tip of the bow, thus preventing yawing of the anchored boat caused by wind.

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

FIG. 1 is a top view of the bow of the boat showing the mechanism,

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

FIG. 3 is a section on line 3-3 of FIG. 2.

FIG. 4 is a section on line 44 of FIG. 3.

FIG. 5 is a partial front view of the bow while the anchor is being hauled aboard.

FIG. 6 is a sectional detail showing means for pulling the anchor shank into and through the hole at the end of anchor arm.

FIG. 7 is a top view showing a more clarified illustration.

FIG. 8 is a section on line 8-8 of FIG. 7, including Wiring diagram.

Referring to the drawings in which like characters and numerals of reference refer to similar parts throughout the several views, the numeral 7 denotes the bow of the boat and 8 the deck thereof. Attached by fasteners 9 onto the deck is the longitudinal base 10 having a longitudinal slot 11 therein as shown, see FIG. 1. A transverse shaft 12, mounted in bearings 13 is at the forward end of slot 11. Mounted at approximately right angles to each other are projecting anchor arm 14 and pulley arm 15 to shaft 12 as better illustrated in FIGS. 2, 3 and 4, bolt 16 allowing adjustable attachment thereto. Helical springs 17, encircling shaft 12, have one end of each spring attached to the arms 14 and 15 at 18 while the other end of each spring is attached to the bearing at 19, see FIGS. 3 and 4. The arms 14 and 15 may therefor be in tensional relation with bearings 13.

The bearings 13 are attached to the bottom of deck 8 by means of fasteners 20. To the outer end of anchor arm 14 is an elongated hole 21 through which the anchor rope 23 passes followed by the anchor shank 22, the disclike fluke 24 always remaining on the other side of arm 14. At the outer end of pulley arm 15 is mounted, between the two parallel arms thereof, the rope pulley 25, over which anchor rope 23 passes as better illustrated in FIG. 2. This rope 23 then passes through slot 11 in base 10, through slot 26 in deck 8 and around fixed pulley 27 to any desirable rope manipulating means such as a reel 28, rotated by handle 29 in the direction of arrow 30 when hauling the anchor aboard. A ratchet wheel 31 together with pawl 32 prevents rope 23 from unwinding in the direction of arrow 33. It will be apparent that any appropriate mechanical or electrical means may be employed for manipulating rope 23, either 3,261,319 Patented July 19, 1966 in the direction of arrow 33 or 34. It is well within my understanding and capability to design an electrical pushbutton control for manipulating rope 23 to either cast the anchor into the water or haul it into the boat in conjunction with the mechanism herein disclosed. On small boats the anchor rope 23 would be manipulated by hand. The rope 23 passes through hole 35 in the upper end of shank 22, see FIG. 6, where it is prevented from pulling out by clamp 36. Separate circular beads 37 and 38 loosely encircle the rope 23 as shown, the upper head 37 being slightly smaller in girth than the lower bead 38 and which bead is also slightly smaller than the rounded upper end 39 of shank 22. It will also be noted that the lower ends or base of each bead nest into the upper rounded end of the next lower bead or rounded end 39 of shank 22. With this arrangement, the anchor shank 22 can easily be pulled into and through the chamfered hole 21 at outer end of anchor arm 14 at an angle as illustrated in FIGS. 2 and 6, the beads providing the proper bevel and swinging the rounded tip 39 of shank 22 away from the edge of hole 21, where it might otherwise be jammed, towards the center of hole 21.

The operation of this boat anchor is as follows; assuming the anchor is being hauled into the boat, see FIG. 2, the anchor rope 23 being pulled in the direction of arrow 34 around fixed pulley 27 and pulley 25 at end of pulley arm 15, the anchor being indicated by dotted lines 24A, the anchor arm 14 being cantilevered over the bow of the boat as indicated by the dotted lines 14A, in this manner permitting the anchor to be hauled up without its edges scraping the side of the boat. This is also the extreme outward position of the anchor arm 14A as urged by the springs 17, the upper side of the flat base 10 preventing further downward movement thereof. During this operation, the pulley arm occupies a position indicated by the dotted lines 15A, its upright position permitting a satisfactory angular pull on the rope 23 so that the shank 22A will be pulled through elongated hole 21 at the end of anchor arm 14A up to the fluke 24A. At this point, as there can be no further movement of the anchor relative to the anchor arm, the anchor arm 14A is pulled upward, against tension of springs 17, into the position shown by the full lines, the shank 22 being now at an acute angle relative to anchor arm 14, due to elongated hole 21, as will be readily understood, the pulley arm 15 now being at right angles thereto, as shown. A still further pull on rope 23 will cause the pulley 25 to describe the are 40, the pulley arm 15 passing through longitudinal slot 11 in base 10 and slot 26 in deck 8 and assume the vertical position illustrated by dotted lines 153, the rope 23 meanwhile being detached from pulley 25 and transferring its pull directly to the anchor shank 22 which at the next moment passes through slots 11 and 26 in an upside down position as shown by dotted lines 22B, the fluke 24B coming to rest upside down onto top of deck 8 where it is inconspicuous as well as out of the way. During this operation, the springs 17 have been resisting this one-half rotation of shaft 12 so that, when the rope 23 is released from its fastening, the anchor will immediately reverse its heretofore described trajectory and plunge into the water, automatically, the springs 17 being the motive power in this instance.

To prevent side strain onto the cantilever extending anchor arm 14 when the boat is at anchor, the arm 14 is flanked on each side by the front end of base 10 which is securely bolted to deck 8 by fasteners 9. Chocks 41 may be on either side of base 10, see FIG. 5, for further strength and convenience, a rope 42 being shown therein, the forward and central placing of this anchor manipulating means therefor not interfering with the subsequent operation of mooring the boat. Also, it is quite customary, excepting in some smaller boats, to

secure a flag-pole socket at the tip of the bow, and as it is herein now necessary to displace same by this anchor manipulating means, the fiag-pole socket 43 is herein secured to the meeting ends of two curved arms 44, the other end of each arm being attached to opposite gunwales of the boat at 45, the socket 43 thus being directly over the tip of the bow as heretofore, the flagpole being indicated by 46 and not interfering with the manipulation of the anchor as will be apparent, the curved arms 44 incidentally serving as a holding on means for fishermen, etc. It will be apparent that rope chocks may also be an inherent part of base 18 as indicated by numeral 48 in FIG. 5. It will also be noted that, when pulling up the anchor, the pull of the rope always remains at a practical angle, from its original vertical pull at the bow of the boat to its eventual upside-down position on deck, causing the anchor arm and the pulley arm together to execute a full half turn, the anchor arm covering slot 11 in base and deck 8 while pulley arm occupies a position underneath the deck in a depending vertical position at the front end of the how, when the anchor has been hauled into the boat.

In the above description the anchor rope was assumed to be pulled by either manual or mechanical means, depending on the size of the boat, etc., but when manipulate-d by power, such as an electric motor 51 which, through pinion 52 and gear 53 rotates the reel 28 on shaft 54 in the direction of arrow 30, the same mechanism may be used. An electro magnet 55, placed directly above pawl 32, see FIG. 8, will pull pawl upwards out of restraining contact with teeth of ratchet wheel 31 and permit the reel 28 to unwind rope 23 through spring tension applied to anchor arm 14 by springs 17 and cast anchor 24 into the water by swinging it into an 180 degree are as indicated by dotted line 40 when push button 56 is pressed, battery 57 furnishing the energy therefor. This part of the circuit is closed through wires 66, 67 and 68 together with battery 57 and push button 56. When sufiicient slack rope has been unwound from reel 28, pressure on button 56 is released, pawl again restrains reel from unwinding and the boat is at anchor. During this operation, limit switch 58, which had previously interrupted the circuit to motor 51, will now close through pull of spring 59 in the direction of arrow 66), closing the motor circuit through wires s1, 62, battery 57, wires 63 and 64 and push button 65, thus energizingmotor 51 and hauling in anchor 24 when push button 65 is pushed.

In FIG. 8 is illustrated means for manipulating the rope guide arm 15 by attaching it to anchor arm 14 with flexible pulling and restraining means such as chains 70 and 71, shown by dotted lines, on either side of guide arm 15, the other end of chain 70 being attached to arm 14 while the other end of chain 71 is attached to deck 8 as shown. This construction permits anchor arm 14 to gradually pull guide arm 15 forward, while anchor 24 is being cast, thus maintaining a suitable pulling angle on rope 23, the chain 71 preventing guide arm 15 from exceeding the preferred vertical position, as noted by numeral 1415. Dotted lines 23A denote positions of anchor rope during the movement of anchor 24 to that illustrated at 24A at the bow of the boat, While 23B indicates the rope while arm 15 is in vertical position. This construction eliminates the need for slot 11, either in base 10 or deck 8 shown in FIG. 2, and substitutes therefor the hole 26. In this latter case, FIGS. 7 and 8, the arm 14 is securely attached to shaft 12 as in FIG. 2, while arm 15 is loose to swing thereon, the chains 70 and 71 now controlling the movement of guide arm 15.

From the foregoing description it will be apparent that I have evolved a boat anchor and manipulating means therefor which can be conveniently operated from the pilot house, the rear seat or any other desirable location on the boat, the boat thus being capable of being operated by one man instead of at least two, the manipulation of the anchor being also conveniently operable by means described in my Patent No. 3,068,828, issued December 18, 1962, depending largely on the size of the boat, etc., the anchor occupying an inconspicuous and non-interfering place on deck when the boat is under way or moored to a dock or tied to a mooring buoy, while the displaced flag-pole socket and running light may still be located at the tip of the bow of the boat, this anchor manipulating means being also adapt-able to be located on either side of the center of the bow of the boat as circumstances may dictate.
