Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed February 19, 1917'. Serial No. 149,663.

To all whom it may concern:

Be it known that I, JOHAN E. JOHAN- NESSEN, a citizen of the United States, and resident of the city of Brooklyn, in the county of Kings and State of New York have invented certain new and useful Improvements in Anchors, of which the following is a specification.

This invention relates to improvements in marine anchors and has for its object to provide a pair of fluke carrying arms formed separate and independent of the shank of the anchor and also separate and independent of each other, these arms being provided with means whereby they may be readily and securely attached to the shank without welding.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1- is a side elevation of my improved anchor showing a bolt by which the fluke arms are secured to the shank.

Fig. 2 is an edge view of the anchor.

Fig. 3 is an enlar ed view partly in section of the outer end of the anchor showing the arrangement of the bolt which secures the arms to the shank.

Fig. 4.- is a perspective view showing the outer end of the shank as grooved longitudinally; also showing the laterally extending lip for limiting the outward movement of the arms on the shank.

Fig. 5 is a perspective view howing the dovetailed slot in the head end of one of the fluke arms.

Fig. 6 is asection on line 6-6 of Fig. 3 looking in the direction of the arrow.

Referring to the drawings, 10 designates the shank member of the anchor, the lower end of which is slightly enlarged, as illustrated in Fig. 4, and provided with longitudinal V shaped grooves 11 in two of its opposite edges. The opposite faces 12 at the lower end of this enlarged portion of the shank are each provided with a laterally extending lip 13.

The arm members 14 of my improved anchor are formed separately and independently of the shank 10 and'also separately and independently of each other, each being provided with an enlarged or head portion 15 of the shank, and its edges 17 engage the V- shape groove 11 in this shank, the lower end of this head resting against the laterally extending lip 13 on the shank for the purpose of forming a stop therefor, to assist the bolt in holding or resisting the load or pull, and to prevent the arm from coming off and permitting the anchor to let go even if for any reason a fastening bolt should become broken or accidentally removed.

In order to provide means for positively connecting these fluke arms to the shank, I pass a bolt 18 through the holes 19 in the shank and through the holes 20 in the head portions of the arms thereby securely connecting all of the members together.

My improved anchor may be constructed with much less expense than the ordinary anchor which has the fluke arms welded to the shank. Then again the enlarged head portions of the fluke arms serve to supply additional weight to the anchor at the point where the weight is most desired; third by my improved construction different parts of the anchors may be carried, taking up the minimum amount of space both in transportation and also in storing them upon the ship, and the parts may be readily assembled when desired it being only necessary to slip the dovetailed heads ofthe two arms down over the groove portion of the shank,past the bolt 18 through both, and the whole is assembled and ready for use.

The parts are formed of steel castings, and need absolutely no machining and the recess 21 in the head, after the nut has been applied to the bolt, may be filled with putty,

I desire it to be understood that I do not restrict myself to the exact construction shown and reserve the privilege of resorting to all the mechanical variations compatible with the spirit of the invention to which the device is susceptible, the invention being defined by the appended claims.

5 pendent of said shank said beinggrooved to receive said shank, and means for securing said arms to said shank.

2. An aIlChOI' COIIlPIlSlIlg a shank, a palr of fiuke-carrying'arms formed independently of said shankzand of eachother, and a bolt for rigidly securing said arms directly to, said shank.

3. An anchor comprisin a shank grooved longitudinally at one end a pair offiuke 5 arms, each having a. groovedhead With a "j pair of retaining lips to-engage the groove in: the shank and retain-these, members in fixed relation to each other, and means for preventing accidental removal of said arms from said shank.

4.. An anchor comprising =zLjShlIlk having V shaped longitudinalgroovesatone end, a pair of fluke arms each having a head por- -tion with a dovetail groove on its inner face and its opposite edges entering the opposite 'Vs in "said shank, stop ribs ontheshank to engage saidarms, and a bolt rigidly securing said arms to the shank.

In testimony whereof I afliX my signature in presence of a Witness.
