3 Claims. 1

The present invention relates to improvements in anchor assemblies.

Anchors commonly used have the stock xedly mounted on the shank of the anchor, the arms of the stock extending at right angles to the direction of extension of the fluke arms of the anchor. This relation between the arms is employed to increase the ability of the anchor to become engaged under actual service conditions. In such structures, the hawser is secured to the stock zone of the anchor. Because anchors of this type present awkward conditions when hauled in under inboard stowage conditions, they offer undesirable obstacles to movement about the deck, and may foul the rigging. When suspended outboard, the arrangement is awkward, due to the fact that the right angular relationship of the stock arms and uke arms practically forces an undesirable contact condition, since the tendency is to set up an angular contact condition in which the -contact is by the end of one of the stock arms above and the contact oi one of the flukes at the bottom of the anchor shank, with the points of contact on opposite sides of the shank.

Various ways for avoiding the rst of these conditions have been contemplated. For instance, making the stock removable permits the iiuke end to lie flat, thus mitigating somewhat the ori-deck difiiculties, but the removal unts I the anchor for immediate use in an emergency.

Another solution proposed is that of making the stock. separate from the shank but permanently connecting them in such way that the uke end can be given a quarter turn relative to the stock by a relative movement of the shankk and stock longitudinally of the shank. In such arrangement the hawser is secured to the stock so that the Weight of the anchor and its shank when outboard will cause the assembly to elongate as to length, and during elongation the nukes will be rotated to the right angular relationship for the service conditions. Such structure permits the length to be contracted by rotation of the stock portion a quarter turn, a condition which places the arms of the stock and ukes as extending in the same direction, a condition which will permit of better stowage conditions inboard, and, at the same time set up the conditions of the fixed anchor structures during anchoring service due to the right angular relation of the stock and uke arms when the assembly is in its elongated length form.

However, such assemblage is disadvantageous if the attempt is made to position the anchor outboard and suspended. This is due to the fact that since the hawser is connected with the stock zone, and the latter is uppermost, the tendency is for the stock to lie at against the side of the boat during positioning, and since the anchor and shank are connected in such way that any longitudinal movement causes the shank and iiukes to rotate, the weight of the suspended anchor causes the anchor assembly to elongate lengthwise. Assuming that it had been placed outboard in the contracted length condition present during inboard stowage, such elongation will cause the fluke arms to be rotated the quarter turn and thus practically present a iiuke as pointing toward the side of the vessel. Even if the vessel side and uke be out of contact, any rolling of the vessel would permit such contact to be had under power conditions with possible damage to the boat; the condition arises through the fact that the stock end retains its parallel relation with the side of the boat, thus permitting the fluke end of the anchor to swing through its quarter turn path under the weight of the anchor. Hence, while the latter structure will permit proper stowage inboard, and present the usual service conditions outboard. the positioning of the anchor in suspended outboard position is practically prohibited, due to the above conditions.

' The present invention is broadly of the latter type, but certain changes have been made in the relationship of elements, with the changes such that not only are the advantages of the type retained, but, in addition the invention permits the anchor to be located in outboard suspended position without presenting the disadvantages of the type above explained.

Another object of the present invention is to provide a marine anchor that can be economically constructed and yet will always lay hold of the earth when in use.

Other objects of the invention will bein part obvious and in part pointed out in the following description of the accompanying drawings, wherein,

Fig. 1 is a top elevation of the anchor accorde ing to the present invention.

Fig. 2 is a side elevation of the anchor as in stowed position on a vessel.

Fig. 3 is a top partial view of the anchor showing the shank with the top portion thereof in cross section.

Fig. 4 is a side view of the anchor in holding position on a river bottom or the like.

Fig. is a cross sectional detail view taken on line 5-5 of Fig. 7.

Fig. 6 is a cross sectional detail view taken on line 6 6 ,of Fig. 7, and

Fig. '7 is an enlarged detail view of the top portion of the anchor shank with cable attached and with the upper portion thereof in crosssection.

Referring now more particularly to the drawings, numeral I indicates the anchor shank, 2 the arms which extend transversely of said shank and 3 the flukes each of which form the pointed broad end of one of said arms. While not shown, said arms 2 can be pivotally connected at their base end to shank I as is common practice in anchors of the present type.

Shank I consists of two telescoping parts 5 and 6 of which 6 is a tubular member or head that slides over the top end of part 5. Part 5 is a barrel Vzone formed with a longitudinal bore I formed in its top end portion and also a pair of oppositely directed spiral slots 8 extending therethrough to said bore but only for a portion of the length of said bore.

A rivet 9 extends across said barrel Zone 5 and its bore 1, with the rivet heads ush with the periphery of said bar. A tubular connecting member I!) is pivotally mounted on said rivet 9 chain I I to barrel zone 5.

Tubular head 6 has a pair ci' bolts I5 screwed through threaded openings I5 formed there through diametrically opposite to one another. The ends of said bolts I5 each extend into one of said spiral slots 8 of barrel zone 5. A stock 2% extends transversely through said head 6.

Stock 25 is positioned on head 8 parallel to said bolts I5 and also arms 2 when bar 5 and vwithin bore and thereby connects cable or head 5 are in their maximum extended position with bolts i5 at the top of slots 8 as shown in Fig. 7.

When stowing the anchor for instance on the deck of a vessel, arms 2 are laid at on the deck and stock with head 6 is rotated on barrel zone 5 until said stock is parallel to said arms. The anchor will then lie on the deck as shown in Fig. 2. In this position of the parts the anchor assembly is in its extended length condition.

lf itbe desired to place the anchor in an outboard position but suspended, as when preparing the anchor for instant dropping, it is retained in its extended length condition used in stowing inboard, thus retaining the arms of stock and flukes as extending in the same direction, and the anchor raised and passed over the top rail at the side and lowered. Since the asremol' is already in its extended length status, the weight of the anchor has no effect as a turning agent with respect to the stock, and since the anchor shank is connected with the hawser through the barrel Zone 5, the anchor weight is being carried by the hawser and not by the stock.

As a result, not only is the fluke end oi the anchor positioned parallel with the side, but the stock arms have a similar relation to the side when the anchor is being placed in such position. However, due to this parallelism between the pairs of arms and the sides of the boat, the anchor is suspended closer to the side of the boat, with the nukes at both ends practically positioned in such manner as to be non-damaging 'to the boat side. And since the upper end of the shank is directly lconnected with the hawser through thebarrel zone, the stock end of the anchor is close to the side, a position provided by the extended length condition of the as sembly while the latter was being passed outboard, so that the weight of the anchor is active to retain this condition. The only condition which could be active in producing a change in the relation of the arms of the stock and flukes is the weight of the slidable element 6, which has not connection with the hawser, and the weight of the element is small as compared with that of the anchor. Thus, the stock, in such position will not rotate materially, due to the fact that to permit such rotation the upper end of the shank and the adjacent Zone of the hawser would need to be swung outward a distance suflicient to permit the arm length of the stock to be interposed. Such outward swinging would be practically impossible with the weight of the element 6 as the only possible active agency. The weight of element 5 would be suiiicient to swing one of the balls at the end of one arm 26 in Contact with the side of the boat, but the contact value would be simply that oi the weight and wholly undamaging, especially since it is apparent that should the anchor swing, the contact would simply cause the element to move in the reverse direction, due to the greater power presented through the weight of the anchor and hawser acting in opposition to the weight of the element 6.

However, as soon as the suspended anchor is lowered suicient to permit element 5 to provide its complete quarter turn movement without interfcrence by the side of the boat, the stock will swing to the right angular relation to the anchor fluke end, due to the weight of the element, thus contracting the length of the assembly and placing bolts I5 at the lower closed ends of slots 8, thus placing the anchor assembly in the desired service condition. While the assembly, in such condition, presents the conditions of a contracted length, this fact does not aiect the service operation, since bolts I5 are in Contact with the trailing closed ends of slot 8 and the pull through the hawser .isy placed on the anchor shank and not upon the stock Zone. As a result, any advance of the fluke end will correspondingly advance the stock end, thus maintaining the right angular relationship, since the latter can be changed only by rotating one or both parts relative to each other with the required direction of rotation such as to actually increase the length of the assembly from the contracted length used in service. Pulling stress through the hawser could not move the element S in a direction to increasethe length of the assembly.

From the above it can be understood that the disclosed assembly operates, wheny on the bottom, similar to and with equal eiciency to the usual anchor structure with its fixed stock; when on deck it permits of stowage with the fluke and stock arms extending in the same directions. Its greater advantage, however, comes through the fact that the assembly can be placed outboard in suspended condition without setting up danger to the side of the boat, since both the fluke end and the stock end are retained within the same direction position of the arms of the fluke end and the stock, made possible by the fact that the assembly is in its extended length condition when the arms havev the"sarne direction status so that there is no further extension possible when the suspended condition is set up.

5 is held inactive through the contact of its arms with the side of the boat. y

A vertical pull on chain Il releases flukes 3 as is the normal practice whereby the anchor can be withdrawn into the boat.

It is to be appreciated that the construction herein shown is by way of an example only and is capable of considerable modification, but such changes thereto as come within the scope of the appended claims is deemed to be part of my invention.

I claim:

1. In an anchor assembly having a stock and its arms, a shank, fluke and hawser, wherein the stock is permanently remote from the iiuke and is mounted on the shank and movable thereon longitudinally of the shank, and wherein the stock and shank are operatively related to cause rotative movements of shank and stock by such relative longitudinal movement Within a quarter-turn range to thereby permit the iiuke and stock arms to extend in the same direction or in directions approximately at right angles to one another, an assembly of such type including such stock, shank, fluke, stock arms and hawser, said assembly having the fluke and stock arms in constantly spaced relation in opposite end zones of the assembly, said assembly having means carried by the shank for securing the hawser directly to the shank and independent of the stock,

the shank and stock having cooperative means to produce the rotative range by camming action with the cooperative means so related that when the assembly is in its extended length position the uke and stock arms will extend in the same direction and with said arms having the relative right angular directions of extension when the 'assembly is shifted into its contracted length y that the pin formations are carried by the annular member with the slot formations carried by the shank.
