Specification ofletters Patent.

Patented July 15, 1919.

Application filed November 22,1918. Serial N 0. 263,749.

To all whom it may concern:

Be it known that I, JOHN TAYLOR, a subject of the King of England, residing at East Boldon, in the county of Durham, England, have invented certain new and useful Improvements in or Relating to Ships Anchors, of which the following is a specification.

My invention relates to improvements in anchors of the type in which the flukes are pivoted and are carried by the shank, the principal object of which is to enable such anchors to house closely and firmly to the ships side, without requiring the shell plating to be recessed or metal pads to be fitted to receive the ends of either flukes.

According to the invention the head or fluke portion of the anchor is cast or forged in two pieces, which, by means of a check arrangement the two pieces are allowed to have a few degrees independent angular movement which will allow the flukes of the anchor to adjust themselves to fit the ships side.

The invention is illustrated in the accompanying drawings, in which,

Figure 1 is a plan view; Fig. 2 a side elevation with one head or fluke portion re moved; and Fig. 3 is a view on the back of the head.

The head or fluke portion of the anchor shown is made in two pieces C, and C held in position and connected with the shank A, by the spindle B, which passes through a hole in the two portions C and C and the shank A. The ends of the spindle B are threaded to receive two nuts D, which are made secure on the spindle by means of a rivet, or bolt, or a tapered pin as E.

At the portion where the two head portions 0 and C meet, a check arrangement is formed by the projection a on the head piece C, which fits into the recess d in head piece C The projection a may be made less in length than the length of the recess 03, which will allow the head portions 0 and C to have a limited amount of independent angular movement, the required amount of which will be governed by the form of the ship about the hawse pipe, on which .the anchor is to be housed. High speed passenger vessels would require about 15 degrees, while in merchant vessels, 5 degrees would be ample.

It will be seen that this independent angular movement of the two head pieces C and C is a separate movement of a few degrees which the aforementioned two parts have in addition to the ordinary oscillation which the head portion has in respect to the shank, and which is usually one quarter of a circle.

Furthermore it will be seen that this se arate angular movement does not inter ere with the ordinary action of the anchor when in the ground, as both head portions will oscillate to the usual one quarter circle when the faces S on the head portions C and C touch the shank A.

In anchors according to this invention, the two fluke portions have a slight independent oscillation sufficient to enable the flukes to adjust themselves to fit the ships side; and it will house close and tight and will not shake or hammer about when the ship is in a heavy sea, and Will fit hawse pipes made for other types of stockless anchors of a similar weight.

Furthermore it will not require the fore end of a ship to be fitted with wood to insure perfect housing of the anchor.

While one mode of construction is shown which provides the limited independent movement of the flukes described, it is to be understood that other modes of construction may be used which will allow one or both fluke portions to have a limited amount of independent oscillation, irrespective of the ordinary oscillation of about one quarter of a circle, which the anchor head generally has in relation to the shank.

What is claimed is 1. In an anchor the combination of two flukes; a spindle on which the flukes are supported; a recess and a projection on the adj acent ends of the bosses of the flukes; and a shank through the head of which the spindle passes.

2. An anchor comprising a shank, abutting flukes pivoted at one end of the shank and on opposite sides thereof, and means between the abutting ends of the flukes to permit of the flukes moving slightly on their pivot independently of each other.

3. An anchor comprising a shank, a pivot pin extending through one end of the shank, abutting flukes mounted to turn on the ends of the pivot pin, one of the flukes having a projection, and the other of said flukes having a iecess of greater Width than the name to this specification in the presence of Width of the pro] ection and in which the lattwo subscribing Witnesses.-

ter fits, whereby the fiukes will be permitted to have a slight movement independent of JOHN TAYLOR 5 each other, or both fiukes may turn together Witnesses:
