1 Claim. (Cl. 114-221) This invention relates to a device for positioning and securing an anchor in position on the deck of a boat.

It is in general the broad object of the present invention to provide a novel and simple structure which can be readily atfixed to the deck of a boat to position and to secure an anchor in place. As is well-known, a pivoting fluke anchor includes a pair of fiukes joined together as a unit and hingedly mounted at the end of a shank, the anchor including a suitable crown structure at the rear of the flukes to enable the flukes to engage bottom promptly. As typical of anchors with which this inven tion is particularly concerned, one can refer to the anchors shown in Patents 2,249,546, 2,320,966, 2,354,666, 2,510,867, 2,576,390, 2,641,215, and 2,643,631.

The invention includes other objects and features of advantage, some of which, together with the foregoing, will appear hereinafter wherein the present preferred form of anchor positioning and securing device of this invention is disclosed.

In the drawing accompanying and forming a part hereof, Figure 1 is a plan view of the device shown with an anchor in position on the deck of a vessel.

Figure 2 is a plan view of the device in place on the deck of a vessel, the anchor being omitted for clarity in illustration.

Figure 3 is an end view of a crown supporting device.

Figure 4 is a section taken along the line 4--4 in Figure 3.

Figure 5 is a plan view of the shank securing device.

Figure 6 is an end view of one of the devices utilized to secure the point of the fluke.

Referring to the drawing, and particularly to Figure 2 thereof, the device of the present invention comprises a crown securing device 7, fluke point supporting devices 8, and a shank end supporting device 9. Each of these is secured to the ships deck 11 as by suitable screws 12.

The crown supporting device includes a crown support plate 13 having a pair of upstanding cars 14 thereon, these being bent over as at 16 and flaring outwardly and upwardly from the plate 13 (Figure 4) to receive and retain some portion of the crown such as one of crown plates 17. Thus, referring to Figure 1, the anchor there shown corresponds to that shown in Patent 2,641,215, and includes spaced crown plates 17 mounted at the rear of flukes 18, the latter being hinged at the rear end of shank 19 while a stock 21 is positioned transversely at the rear end of the fiukes. The forward end 22 of the shank is provided with suitable cable attachment means, such as a shackle, this being attached in turn to a chain or cable, these being omitted from the drawing. Plate 13 also has ribs 20 thereon which follow in a substantially parallel spaced relationship the upward flare of the underside of cars 16 to engage and retain the engaged crown plate.

Each tip or point 23 of a fluke 18 is received in a suitable receptacle 8 including a supporting plate 26 having spaced vertical walls 27 and 28, the walls being at an angle to one another corresponding substantially to the angle of the tip or point of the fluke.

The shank end support means 9 includes a base plate 31 having an upstanding cleat structure 32 thereon, the cleat structure being slotted as at 33 to receive the end of the shank. The cleat structure enables a piece of cord to be passed about the ears 34 of the cleat and over the end of the shank to secure the latter in place when the crown plates are securely retained by the crown support means 7.

The crown support means, the fluke tip support means, and the shank end support means have been shown as fabricated from separate elements so that these can be conveniently manufactured to provide a structure having a minimum of weight and which may be secured in any desired position on the deck of a boat or ship. If desired, however, the three structures or any combination thereof can be provided integrally on a suitable base plate which, in turn, can be mounted upon the deck of a boat with the four elements arranged in a predetermined and selected position.

From the foregoing, we believe it will be apparent that we have provided a relatively novel, simple and improved device for positioning and securing a pivoting fluke anchor upon the deck of a boat.

We claim:

A hold down device for securing to a ships deck a pivoting fluke anchor having twin flukes, each fluke hav ing a pointed end, the anchor also including opposite planar crown plates which extend generally parallel to the flukes and which are spaced apart at the rear of the anchor, the anchor having a shank extending forwardly beyond the points of the fiukes, said device comprising a crown support adapted to be secured to said ships deck to support the crown end of the anchor and having spaced, slotted ears adapted to receive and fit over the underside of a crown plate in a locking engagement therewith, the slots in said ears being parallel to the deck so that the crown is secured against vertical as well as horizontal dislodgment, a pair of triangular receptacles each adapted to be secured to said ships deck in a position corresponding to that of a fluke point when the crown plate is locked in the ears on the crown support, each receptacle corresponding cooperatively to the fluke point resting therein to retain such point in a locking engagement when the crown plate is engaged with the slotted ears of the crown support, and a cleat adapted to be secured to said ships deck in a position corresponding to that of the forward end of the shank when the crown plate is locked in the ears on the crown support and the fluke points are in said receptacles, said cleat having a slot on its upper side provided between opposite spaced arms on the cleat, said slot being adapted to receive the shank end, and said arms extending outwardly and downwardly to provide rope-fastening ears to secure the shank in said slot.
