To all whom it may concern:

Be it known that I, ACI-IILLE CArrmcoI, Esq., of Leghorn, Italy, have invented certain new and useful Improvements in Anchors, of which the following is a full, clear, and exact specification.

Stockless anchors have the advantage that they can be easily weighed and brought into position on the bow of a vessel by hauling the shank of the anchor into the hawse hole as far as the head, so that only the anchor fiukes project overboard. Anchors of this type however, have two great defects: 1. Since they are stockless it follows that they cannot take hold on the seabottom so easily, as the main purpose of the stock is to keep the anchor flukes perpendicular in order that the anchor may grip with certainty and ease. 2. The anchor flukes must always remain projecting overboard .which circumstance may give rise to inconvenience in certain special vessels, submarines for example, on account of the resulting unevenness of trim.

The present invention relates to a particular construction of anchor which combines the advantages of the stockless and ordinary types of anchors.

According to this invention the anchor when lying on the bottom, behaves in precisely the same manner as an ordinary anchor provided with a stock, that is to say, its stock lies at right angles to the anchor flukes. As soon, however, as said anchor is weighed and arrives in front of the hawse hole, the stock and flukes fold up together, so that it can be taken inboard, completely, thus presenting a great advantage over the usual stockless type of anchor.

To enable the invention to be fully understood it will now be described by reference to the accompanying drawings in which:

Figure 1 is a view showing an anchor constructed according to one form of the invention, extended ready for letting go. Fig. 2 is a View showing same on the sea bed. Figs. 3 and 1 are sectional views showing the anchor folded and stored in the hawse hole chamber.

As shown the stock is formed by two arms 3, 4, pivoted at 2 to the shank 1, the flukes 13, 14 also being piovted to the head at 12. These arms are provided on one side of their pivot point 2 with eyes 17, 18, connected by chains 19, 20 to the flukes 13, 1a respectively, while on the other side of said pivot point other eyes 5, G are attached or connected by chains 8, 7 to the main cable or chain. The chains 8, 7 are united at 9 to form a loop or ring. )Vhen tension is put upon the main chain or cable the two branch chains 7 8 pull thepivotedarms 3, 4., into a horizontal or extended position, the motion of said arms being limited by stops 10, 11 on the shank 1. The chains 19, 20 are of such a length as to allow the flukes 13, 1 1 to drop into the extended position shown in Fig. 1, when the arms 3, 4 are pulled into the horizontal or extended position. When however said arms 3, 4, move downward due to pressure applied to their ends as hereinafter described, the chains 19, 20, act to pull the flukes into the closed position along the shank 1.

The action of the anchor is as follows: The anchor is in the closed position in its chamber under the hawse hole (Fig. 3). If it be taken out and lowered, the arms 3, 4: forming the stock open out during the descent, either by the weight of the fiukes 13, 14 pulling the chains 19 and 20, or else on account of the tension of the branch chains 7 and 8, so that when the anchor reaches the sea bottom it acts like an ordinary anchor, inasmuch as it lies with its stock horizontally on the bottom, the lower fluke being ready to bite (Fig. 2). The upper fluke which does not bite, will fold up under its own weight.

"When the anchor is weighed, the procedure is the same as with an ordinary anchor, but as soon as the anchor enters the mouth of the hawse hole, the ends of the arms 3 and 1 (Fig. 3) press against the sides of the hawse pipe and the arms fold up together, and this operation by means of the chains 19 and 20 causes the anchor flukes 13 and 14 to collapse against the shank and the anchor is able to be pulled entirely inside the chamber as shown.

WVhat I claim is:

An anchor-having pivoted flukes and a stock formed of two pivoted arms, and chains connecting each arm on one side of its pivot point to a fluke of the anchor and on the other side of its pivot point to the main chain or cable, in such a manner that when my name in the presence of two subscribing the said arms are depressed or folded to- Witnesses.

ward the shank the fiukes of the anchor are also caused to fold in upon the shank, thus AGHILLE CAPPRICOI' enabling the anchor to be drawn entirely WVitne'sses: into a hawse pipe or chamber. GUST I-IOWARDI, In Witness whereof, I have hereunto signed A. BORAGINO.
