PATRICK J. RYAN, OF BROOKLYN, NEW YORK, ASSIGNOR OF ONE-HALF T0 RICHARD DOUGHTY, OF NEW YORK, N. Y.

ANCHOR.

Patented Dec. 31, 1918.

Application filed. October 12, 1917. Serial No. 196,150.

To allwhom it may concern."

Be it known that I, PATRICK J. RYAN, a citizen of the United States, and a resident of 2142 80th street, Brooklyn, in the county of Queens and State of New ,York, have invented certain new and useful Improvements in Anchors, of which the following is a specification.

My invention relates to an improvement in anchors for vessels but particularly to anchors of the stockless type and has for its object the provision of a means for causing the anchor fiukes to quickly and positively embed themselves in the mud or sand at the sea bottom when the anchor is brought into use.

The old form of anchor which comprised a stock and finkes integrally forged therewith has been almost entirely superceded by the stockless type. This latter type has a shank to which the crown is pivoted in such a way that the flukes, carried by the crown, may swing to either side of the shank aproximately 45 degrees for engaging with the sea bottom. The swinging of the flukes, when the anchor is brought into use, is accomplished by a widening of the crown at the rear which drags in the sand or mud on the sea bottom and causes the fiukes to swing downwardly into position. It is obvious that this action is not a positive one and that the fiukes do not always engage quickly; therefore I have provided in my invention a tripping device pivoted to the crown that engages as soon as the anchor is grounded and which, through this engagement immediately forces the flukes into the bottom when the first strain comes on the cable.

The objects of my invention as set forth above and others that will later appear together with the particular methods of attaining these are now to be described and are illustrated in the accompanying drawings forming part of this specification.

Similar characters of reference denote like or corresponding parts throughout the several views; of which Figure 1 is a side elevation of my invention, partly in section A, B, C, D; Fig. 2 is a vertical cross section on lines E, F, G, H of Fig. 1; Fig. 3 is a perspective view of the tripping device of my anchor.

Referring particularly to Figs. 1 and 2 of the drawings, numeral 1 represents the anchor crown to which the flukes 2 and 3 are attached preferably by an integral casting. The crown 1 has a rectangular pocket 4 cored from the rear and this intersects with a slot 5 in the front. At th bottom of the pocket at and on either side of the slot 5 are two semi-cylindrical grooves 6 and 7 which serve as bearing sockets for the gudgeon pin-like projections 8 and 9 of the shank 10. This shank is entered into place, from the rear, before the shackle 11 and the pin 12 are assembled. The extreme inner end of the shank is formed into two gear shaped teeth 13 and 14, extending each, one half the width of the shank end and staggered so as to engage and co-act with two similar teeth 15 and 16 formed on the fluke tripping device 17 which is pivoted by the pin 18 between the crown lugs 19 and 20. Fig. 3 shows a separate view of the tripping device and here is clearly illustrated the manner of staggering the teeth and also the forwardly curved flukes 21 and 22, either of which immediately engages the sea bottom when the anchor is first grounded and when the cable draws the anchor in the direction of the arrow (see Fig. 2) the engaged fluke of the tripping device causes either tooth 15 or 16 to bear against tooth 1A or 13 of the shank and thus throws anchor fiukes 2 and 3 into the bottom.

The tripping device 17 has another function, that of, holding the shank up in its place. It thus performs the additional important duty of tripping the flukes into position without increasing the number of parts over that required in other stockless anchors.

My invention readily conforms to the United States and other Government specifications and can be built as cheaply as any stockless-anchor now being used. Another important feature of my invention is that by causing the anchor flukes to engage promptly all danger of the anchor rolling is avoided and this feature alone is of the utmost importance.

Having thus fully described my invention so that anyone skilled in the art may make and construct the same and without limiting myself to any of the details of construction or arrangement of parts, I claim:

1. In an anchor comprising a crown and fiukes, a shank journaled therein, and means pivoted in the crown and co-acting with the shank for moving the flukes.

3. In an anchor comprising a crown and flukes, a shank journaled therein, and means pivoted in the crown and co-acting with the shank for effecting a relative movement between the shank and flukes.

4. In an anchor comprising a crown and flukes, a shank journaled therein, and bottom'engaging means pivoted in the crown and co-acting with the shank for eiiecting a relative movement between the shank and flukes.

5. In a stockless anchor, means connected to the crown for holding the shank in place and for effecting an angular movement of the shank relative to the crown.

6. In a stockless anchor, bottom engaging means connected to the crown for holding the shank in place and for effecting an angular movement of the shank relative to the crown.

7 In a stockless anchor, means capable of oscillation connected to the crown for holding the shank in place and for effecting an angular movement of the shank relative to the crown.

8 In an anchor comprising a crown and flukes, a shank journaled therein, and means pivoted in the crown and co-acting with the shank through staggered teeth formed on each, for moving the flukes.

9. In an anchor comprising a crown and flukes, a shank journaled therein, and means pivoted in the crown and co-acting with the shank through staggered teeth formed on each, for moving the flukes in either direction.

10. In an anchor comprising a crown and flukes, a shank journaled therein, and means pivoted in the crown and co-acting with the shank for moving the flukes in either direction.

11. In a'stockless anchor, means connected to and movable relative to the crown and coacting with the shank for effecting an engagement of the flukes when the anchor is drawn forward on the bottom.

12. In a stockless anchor, crescent shaped Copies of this patent may be obtained for five cents each, by addressing the means connected to and movable relative to the crown and co-acting with the shank for efiecting an engagement of the flukes when the anchor is drawn forward on the bottom.

13. In a stockless anchor, means connected to and movable relative to the crown and c0- acting with the shank, said means being adapted to engage the bottom and through said engagement to efiect a setting of the anchor flukes.

14. In a stockless anchor, crescent shaped means connected to and movable relative to the crown and co-acting with the shank, said means being adapted to engage the bottom and through said engagement to effect a setting of the anchor flukes.

15. A stockless anchor comprising a fluked crown, a shank pivoted thereto, and a fluketripping device movably mounted upon said crown and adapted to cause relative movement between said shank and crown.

16. A stockless anchor comprising a fluked crown, a shank pivoted thereto, and a fluketripping device including means engaging said shank, said shank engaging means being wholly disposed within said crown.

17 A stockless anchor comprising a fluked crown, a shank pivoted thereto, and a fluketripping device movably mounted upon said crown in engagement with said shank for causing a relative movement between the latter and said crown.

18. A stockless anchor comprising a fluked crown, a shank pivoted thereto, and a fluketripping device movably mounted upon said crown in permanent engagement with said shank for causing a relative movement between the latter and said crown.

19. A stockless anchor comprising a fluked crown, a shank pivoted thereto, and a fluketrippingflevice upon said crown in permanent engagement with said shank for causing a relative movement between said shank and said crown when the cable is strained.
