ANCHOR.

SPECIFICATION forming part of Letters Patent No.'358,306, dated February 22, 1887. Application filed December 23, 1886. Serial No 222,383. (No model.)

To all whom it may concern:'

Be it known that I, JOHN TIEBOUT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Anchors and Grapnels, of which the following is a specification.

My invention relates to improvements in anchors having two or more flukes, and has for its object to provide an anchor or grapnel the fluke-arms of which can be turned to such a position that the grapnel can be conveniently stowed away under a seat in aboat.

This invention consists, essentially,in a grapnel or anchor having a shank consisting of two sections united by a pivotal connection, in combination with a sleeve encompassing the shank and movable thereon, and means for locking said sleeve, all of which is more fully pointed out in the following specification and claims, and illustratedin the accompanying drawings, in which Figure 1 represents a perspective view of a I grapnel containing my invention, the same being in a condition to be stowed away. Fig. 2 is a sectional elevation of the same with the flukes in the position they occupy when the grapnel is ready for use. Fig. 3 is a horizontal section in the planer: m, Fig. 2.

Similar letters indicate correspondingparts.

In the drawings, the letters A B designate the two sections of a shank, which are united by a pivot, a, the joint being so constructed that the section A can turn about the section B in one direction and through an arc exceeding ninety degrees, Fig. 1. The fluke-arms G, carrying the flukes 0, are curved, as usual, and are attached to or formed integral with the section A. This latter section is made of such a length that when the fluke-arms 0 are turned to the position shown in Fig. 1 it will not project above the level of the fluke-points, but preferably lie below the same. When the flukes are thus turned about the pivot a, the anchor is in a very compact state, and can be readily and conveniently stowed away under a seat in the boat, so as to be out of the way, which cannot be done with the ordinary grapnel.

To secure the shank-sections A B in line with each other to form a straight and perfectly rigid shank when the grapnel is to be brought into use, I provide a locking device, such as, for instance, a sleeve, D, which encompasses an enlarged portion of the shank A B, and can be moved thereon in the direction of its length, and also rotated about the same. A stop, (1, on the section B limits the upward motion of this locking-sleeveD, when the same is moved in a position to permit the fluke-carrying section to be turned about the pivot a. When the locking-sleeveis over the pivotal connection of the shank-sections A B, the shank is perfectly rigid and the grapnel is ready for use. In order to prevent thelocking-sleeve from being accidentally shifted, I provide the same with a groove or slot, E, that is adapted to engage with avpin, e, on the fluke-carrying section A, to form a bayonetjoint.

()n the end of the locking-sleeve is a collar or bead,f, through which the slot or groove E opens, Fig. 3, and when the slot has been caused to take up the pin e, by lowering and properly turning the sleeve, this collar on the end of the same abuts against the material of the fluke-arms and firmly wedges the sleeve, so that it will not be easily rotated or displaced.

WVhen tlieanchor has two fluke-arms, and is provided with a fast stock extending through its shank, the shank is made sectional, and the fluke-bearing section is pivoted, as before, but is folded about the stock-carrying section in such a manner that the fluke-arms fall nearly below the shank and lie parallel, or nearly so, to the shank.

What I claim as new,and desire to secure by Letters Patent, is-

1. In a grapnel or anchor, a shank consisting of two sections united by a pivotal connection, in combination with a sleeve encompassing said shank and movable thereon, substantially as shown and described.

2. In a grapnel having two or more flukes, the combination of a shank composed of two sections joined by a pivotal connection, a sliding sleeve encompassing the shank and movable thereon, and means, such as described, for securing said sleeve, substantially as shown and described.

8. The combination, with the shank-sections A B, of a pivotal connection whereby one sec- In testimony whereof I have hereunto set tion, A, can be turned about the other in one my hand and seal in the presence of two subdirection, three or more flukenrms carried by scribing Witnesses.
