MOORING BUOY Filed June 13, 1930 Patented Apr. 21, 1931 PATENT OFFICE HABMON P. ELLIOTT, 0F WATER/TOWN, MASSACHUSETTS moonrne IB'UOY iApplication filed. June 13,

This invention relates to mooring buoys for boats. t

The usual mooring buoy or float has a ring to which the mooring cable or rope is attached. 5 With this arrangement it is difficult to pick up the buoy or to attach the mooring rope to the buoy due to the-tossing ofthe boat and the buoy and also to the fact that the boat may have considerable momentum at the time. It is difiicult to judge distance so accurately that the power can be cut oif at such a time that the forward movement of the boat will be dissipated at the time it is alongside the buoy, especially in a wind. It is dangerous to pick up the buoy when the boat is moving even slowly as a heavy boat has much momentum and can not be stopped by holding onto the buoy by the hand. Furthermore, in a choppy sea, it is diflicult to hold the boat and the buoytogether for a suflicient period of time to connect the mooring rope with the ring or other the eye 12so that the pull of the boat on the post is transmitted directly to the chain 14.

attaching devices of the buoy."

"An object of-the present inventionis to provide a buoy with an improved form of mooring means that is so arranged that themooring rope can be attached thereto easily and quickly and will lock the rope positively to the buoy against subsequent unintentional detachment. 1

A further-object of the invention is the provision of a mooring buoy having an upstanding mooring post that has 'a mooring snap-hook at the top, the post and the buoy being so constructed and arranged that when the bight of the mooring rope is dropped over the post, the drag on the rope will automatically cause it to pass up the post and into theengagement of the hook.

Another object is generally to improve the construction of mooring buoys for boats.

Fig. 1 is a view illustrating the invention in a more or. less diagrammatic manner.

Fig. 2 is an enlarged detailof the snap-' hook at the top of the mooring post.

Fig. 3 illustratesa modified form of hook.

Fig. 4 illustrates a modified "construction of the buoy.

As shown in Fig. 1, the buoy 10is of topshape and is large. at the top and tapers in a 1930. Serial No. 460,886.

conical manner to the bottom Where it is provided with an attaching eye12 that is connected withan anchor chain 14: connected to an anchor 16. The buoy preferably is made of sheet metal and is hollow'and water light. In accordance with this invention, the buoy is provided with an upright mooring post 16 which is in the form of a metal rod sufficiently strong to withstand the pull of the boat 18 that is adapted to be connected thereto. Preferably the height of the post above the water line is somewhat greater than the height of the boat so that a man on the deck of the boat can readily slip thebight 20'of the mooring rope 22 overthe top of the post. The mooring post is located at one side of the center ofbuoyancy of the buoy which, in the form of buoy illustrated in Fig. 1, is coincident with the vertical axis of the buoy. The post preferably has an angularly related extension 24. that extends downwardly with in the buoy and is connected mechanically to WVith some types of buoys, however, the'side wall is sufficiently strong, to permit the post to beattached directly to the top thereof so that the extension 2 can be eliminated. It is considered unnecessary, however, to illus- .trate this modification. The upper end of the post 16 has a hook portion 26 formed by the downwardly reflexed end portion 28 of the post so that a space is provided between the body of the post and said reflexed por- .tion in which the rope can be received. The lower end ofthe reflexed portion 28 is provided with a latch one-end of which is. pivoted at 32 to the reflexed portion and the other end of which is held by gravity against the body of the post and thereby closes'the entrance at the bottomof the hook. With this arrangement. when the bight of the rope.

with the post, the rope passes under the latch and raises it and enters the hook. The latch then drops down under the rope and against the body of the post by gravity and thereby retains the rope within the hook. The rope can be released from the hook by is dropped over the top of the mooring post and is then passed upwardly in engagement manually raising the latch so that the rope can be slipped downwardly out of the hook and thereafter upwardly over the hook and off the post.

The hook is so located that it faces towards the center of buoyancy of the buoy or is located between the center of buoyancy and the body of the hook. Thus, in Fig. 1, the hook faces towards the vertical axis or geometrical center of the buoy.

With this construction, when the boat comes up to the buoy the bight of the rope is dropped down over the mooring post. The drag on the rope, due either to the momentum of the boat or to the action of wind on the boat, pulls on the post and tilts the buoy and the post in the manner shown in full lines. Fig. 1-. If the post does not happen to be between the boat and the center of buoyancy of the buoy, the drag on the rope causes the buoy to rotate in the water by reason of the eccentric location of the post until: the post is between the boat and the center of the buoy. This action thus always brings the hook facing away from the boat. The drag on the rope also causes the bight of the rope to ride up on the post and to raise the latch and enter the hook above the latch. which latch falls back into place and thereby automaticallylocks the rope to the post without further at tention on the part of an operative. Thus it is merely necessary to drop the bight of therope over the post to effect the automaticlocking of the rope to the buoy.

VVit-h the type of latch hook above de scribed. it is possible that the tossing of the boat and the buoy may swing the rope into such a position that a part thereof comes under the latch and raises it ano thereby releases the rope from the hook. The latch of F ig. 3 can not be so operated. In this modification the latch consists ofa pair of plates 34 which lie on opposite sides'of the hook and are pivoted at 36 to the lower endofthe refiexed portion 28; The upper ends. or said plates are provided with notches 38 in which the rope is engaged so that the pull o-fthc rope on the plates causes the rope to. be-

iammed' between the ends of the plates and thebottom of the hook. The latch plates are also provided with angularly related depending sections 40 which in the closed posi tion of the latch shown by dotted: lines overlies the opening of the hook and the opposite sides of the body portion of the post. With this arrangement while the rope may be tossed into a position under the latch it engages the inclined sections 40 and by this is guided away from the book.

In the construction shown in Fig. 1'3. the buoy is symmetrical so that the center of buoyancy coincides with the geometrical vertical :I'XlS thereof. In the construction illustrated in Fig. 4;. the buoy 100. is provided with a weight 4121011 one side thereof sothat the side bearing the Weight is the heaviest part of the buoy. The center of buoyancy of the buoy thus lies on that side of the geometrical center of the buoy that is opposite the weight. In this modification, the mooring post 16a is located in the geometrical center of the buoy and thus is eccentrically located with respect to the center of buoyancy as is the case in Fig. 1. In this modification, the hook, not shown, at the end of the buoy, faces away from the weight and toward the center of buoyancy of the buoy. The operation of this modification is the same as has been previously described in connection with Fig. 1. The drag of the mooring rope causes the buoy to tilt and to rotate until the weight is lowermost, in which position the hook is on the side of the post that is away from. the boat so that the bight of the rope automatically slides up. the post and enters and is latched within the hook.
