Description

Patented Sept. 30, 1952 UNITED STATES PATENT once BOAT Ancnda A H 7 Vincent (3.. Benedict, Solvay, Y. Application May 15, 1950, Serial No. 161,914

This invention relates to boat anchors of the twin fluke or navy type, and has for its object an anchor consisting of three main parts, as a body carrying a pair of flukes rigid therewith, a shank extending between the fiukes, and a pivot connecting the inner end of the shank and the body.

It also has for its object a shank having a closed lengthwise slot extending nearly the full length thereof for slidably receiving a, ring or coupling to which the anchor rope is attached, and also this slot extending above and below the pivot or having oppositely extending branches at the inner end of the shank into either of which the ring can enter when the boat is maneuvered to slide the 'ring along the slot to the inner end of the shank when it is necessary to dislodge the anchor to raise it when fouled on the bottom.

The invention also has for its object a stop shoulder on the inner end of the shank above and below the pivot located to coact with complemental stops on the body to limit the relative angle of the flukes and the shank.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is a plan view of this anchor.

Figure 2 is a side elevation, partly in section, of parts seen in Figure 1.

Figure 3 is a view, similar to Figure 2, showing the position occupied by the anchor rope ring after the boat is manuevered for the purpose of pulling the anchor for dislodging the anchor from an obstruction on the bottom of the body of water.

Figure 4 is a fragmentary plan, or edge view, of the pivoted end of the shank of the anchor.

I designates the body provided with suitable flukes 2 spaced apart, the body having a yoke portion 3 intermediate of its end between the flukes, this yoke portion being formed with a slot, or bifurcated. The yoke extends rearwardly, or in the opposite direction, from that in which the flukes extend, and is located at substantially the same angle, or in the same plane as the nukes. The yoke 3 virtually provides the body I with a recess 3A alined with the space between the fiukes and extending to the rear or opposite side of the body to that on which the fiukes are located. The body is also provided with arms 4 at its ends extending beyond the edges of the facilitating the tipping over of the anchor with 2 Claims. (01. 114-208) 2 the flukes fiatwise on the bottom; that is, preventing the anchor from, dragging with the fiukes edgewise of the bottom.

5 is the shank to which the anchor rope is connected, the shank being pivoted on a bolt. 6'

mounted in cored out holes in the bifurcations of the yoke 3, that is in the sidewalls of the. recess 3A. The shank is also formed with a closed slot 1 extending lengthwise thereof, nearly the full length thereof, the slot being for receiving a ring or other coupling 8 to which the anchor rope 9 is attached. This ring is suitably designed so as to be coupled into the closed slot. The shank 5 is also formed at its inner or pivoted end with an enlargement or head portion Ill formed with slots I I which are branches of the slot 1, the branches I I extending in opposite directions from the inner end of the slot 1, that is upward and downward, and are preferably concentric with the pivot pin or bolt 6. The enlargement or head In is formed with stop shoulders I 2 on its rear side for engaging opposite sides of the intermediate portion of the yoke 3, that is opposite end walls of the recess 3A and thus limit the relative pivotal movement of the shank '5 and the body I with its flukes 2, the shoulders I2 being located to limit the pivotal movement to any desired radial angle.

The enlargement or head portion II] of the shank is preferably provided with shields I4 located above and below the pivot 6 and forming rearward continuations of the front edge of the head II] in position so that one or the other acts as a skid when the anchor is being dragged before it takes hold. The skids overhang or underhang the shoulder I2 and the yoke and protect the shoulder I2 from becoming clogged so that the flukes and shank will be free to assume the desired predetermined angle relative to each other.

In operation, when the anchor becomes caught so tight in the bottom or rocks of the body of water that it cannot be pulled up in the ordinary manner, the boatman maneuvers the boat, that is moves it forward if the anchor rope is secured to the bow of the boat, thus causing the anchor rope to slack off the shank 5 to drop and the ring 8 to slide along the slot 1 to the inner end of the shank and enter the one or the other of the branches II of the slot that happen to be on the upper side of the anchor. Pulling upwardly on the rope then lifts the rear end of .the anchor upward, dislodging it from the obstruction in which it is caught.

What I claim is:

1. A boat anchor comprising a body and spaced apart flukes rigidly carried by the body, the body 3 having a yoke intermediate said flukes and extending to the opposite side of the body to that on which the flukes extend and providing a recess alined with the space between the fiukes, a shank having one end positioned in said recess and being pivotally connected to the yoke, said shank being formed with a closed slot extending lengthwise of the shank nearly the full length thereof for receiving a ring for attachment to the anchor rope, said shank. having a pair of spaced apart arms extending outwardly from the shank pivot on each side of the yoke and located in the path of movement of the yoke to limit relative pivotal movement between the yoke and shank, angular skids rigid with said arms and located to overhang said arms and cover the same, and also to overhang that portion of the yoke engaging the arms.

2. A boat anchor comprising a body and spaced apart fiukes rigidly carried by the body, the body having a yoke intermediate said fiukes and extending to the opposite side of the body tothat on which the fiukes extend and providing a recess alined with the space between the fiukes, a shank having one end positioned in said recess and being pivotally connected to the yoke, said shank being formed with a closed slot extending lengthwise of the shank nearly the full length thereof for receiving a ring for attachment to the anchor rope, said shank having a pair of spaced apart arms extending outwardly from the shank pivot on each side of the yoke and located in the path of movement of the yoke to limit relative pivotal movement between the yoke and shank, angular skids rigid with said arms and loctaed to overhang said arms and cover the same, and also to overhang that portion of the yoke engagin the arms, said slot in the pivot end of the shank diverging from the axis of the shank and extending into said arms.
