To all whom it may concern:

Be it known that I, FREDERICK JAMEs JACKSON, citizen of the Dominion of New Zealand, residing at Mahurangi Heads,

Auckland, in the Provincial District of Auckland, New Zealand, have invented certain new and useful Improvements in Anchors of which the following is a specification.

This invention relates to anchors used for mooring vessels and has for its object the provision of an anchor the flukes of which will engage in or obtain a grip of the sea bed, no matter how the anchor is thrown overboard. A further object is to make the anchor collapsible for the purpose of facilitating its handling and stowage.

According to the invention the anchor is provided with a head slidable on the shank,

and from which project flukes curved towards the end of the shank to which the chain or line is attached, and equally spaced around said head.

A stop on the outer or lower end of the shank prevents the head from leaving the shank at said end, while at the other end of the shank it is enabled to pass on to the attached chain or line, so that it may lie more or less flat with the shank.

In the accompanying drawing, in conjunction with which the invention will be further described Figure 1 is a perspective view of the anchor in the position it assumes prior to the flukes engaging in the sea bed.

Figure 2 is a vertical section of the anchor and.

Figure 3 shows same collapsed, for stowing on deck or out of the way.

In the drawing 1 is the shank which is provided at its outer end with a stop 2, for the purpose of preventing the head from leaving the shank at that end.

At its other end the shank is provided with an eye 4 to which is attached an elongated link 5 having connected thereto a ring 6-to serve as a stop.

Letters Patent of the United Serial No. 568,808.

The head 3 is slidable on the shank 1 and link 5, between the ring or stop 6 thereon and the stop 2 at the opposite end of the shank.

The flukes 7 are formed integral with the head 3 and curve towards the eye end 4;

of the shank.

Any desired number of flukes 7 can be provided, the latter being equally spaced around the head 3.

To facilitate the stowing away of the anchor. the head 3 is slid off the shank 1 on to the link 5, until it makes contact with the ring or stop 6. The anchor can then be laid on deck or stowed away, with the head 3 and fiukes 7 lying approximately flat with the. shank 1.

When thrown overboard the pull of the chain or line 8 causes the shank 1 to occupy a position with the eye 4 uppermost whereupon the head 3 slides down the shank against the stop- 2, so that the lowermost of the fiukes 7 are ready for entering or engaging in the sea bed.

By providing the fiukes 7 equally spaced around the head 3, some of the fiukes are always ready to enter or engage in the sea bed.

What I do claim and desire to obtain by States of America is:

An anchor comprising a shank formed with a stop at one end and acting when the anchor is in operative position and an eye at the other end; an elongated link attached to said eye and a ring connected to said link and serving as a stop when the anchor is folded; a head provided with ilukes, slidable on the shank and said link between the first mentioned stop and the ring and a flexible element attached to said ring.

In testimony whereof I have aflixed my signature in presence of two witnesses.

FREDERICK JAMES JACKSON.
