Application September 25, 1950, Serial No. 186,644

el Claims.

The present invention relates to a marine anchor and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided an anchor having an elongated cylindrical body to the lower end of which is centrally afxed in perpendicular relation a substantially cylindrical shaft housing in which is revolubly mounted a shaft which extends outwardly from each end thereof and which has, in turn, affixed adjacent each of its outer ends and outwardly of the shaft housing a uke assembly each of which comprises three outwardly extending equally spaced individual flukes. A spring-pressed pin extends longitudinally through the body of the anchor and normally engages in an opening in the shaft to maintain the shaft in locked relation to the shaft housing. Means is provided for remotely controlling the rod or pin whereby the same may be moved out of engagement with the shaft whereby the shaft will be free to rotate within its housing and hence the body and housing may be revolved upon such shaft when the flukes are engaged in a sea bottom, river bottom or the like. Automatic means is also provided for latching the rod in outward position when the same is drawn outwardly. It has been found that the present construction facilitates the disengagement of the anchor flukes from such sea bottom, river bottom or the like.

It is accordingly an object of the invention to provide a device of the character set forth which is comparatively inexpensive in construction, inexpensive to manufacture and yet eifective and efficient in use.

Another object of the invention is the provision, in a device of the character set forth, of a novel fluke-supporting shaft and novel latching means therefor.

A further object of the invention is the provision of novel remotely controlled means, in a device of the character set forth, for releasing the ukes for-ming part of such device from rigid engagement with the body of such device.

A further object of the invention is the provision of an automatically actuated latch forming a part of the invention. Y

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

Figure 1 is a side elevational view of an embodiment of the invention,

Figure 2` is a front elevational view thereof,

Figure 3 is a sectional view taken substantially along line 3-3 of Figure 2,

Figure 4 is a sectional view taken along line 4-4 of Figure 3,

Figure 5 is a view similar to Figure 3 but showing a rod or pin forming a part of the in vention in disengaged and locked condition, and

Figure 6 is a sectional view taken along line 5-6 of Figure 2.

Referring more particularly to the drawing, there is shown therein a marine anchor having an elongated cylindrical body I0 whose lower end is somewhat enlarged, as indicated at II and which has centrally aixed thereto a transversely extending shaft housing I2. The upper end of the body I has formed thereon a pair of diametrically outwardly extending ears I3 in each of which there is pivotally mounted, as indicated at I4, one of the opposed ends of a substantially triangular eye I5 to which, in turn, is connected an anchor cable I6, as shown at Il.

The housing I2 has revolubly mounted therein a circular shaft I8 which extends throughout the length of the housing I2 and which has integrally formed at either end thereof extensions I9 which are preferably triangular in cross sectional area. A fluke formation or assembly is supplied for each of the extensions I9 and each consists of a hub 20 provided with a triangular opening for the reception of the extension i9 and three integrally formed equally spaced outwardly extending linkes 22 preferably extending radially from the hub zone, the flukes thus forming a symmetrically arranged formation with the ilukes equally spaced. Each of the extensions I9 is provided with an opening 23 adjacent its outer end for the reception therethrough of a cotter pin 24 to maintain the fluke assemblies upon their respective extensions IS. y

Centrally mounted in the housing I2 at a point diametric-ally opposite the enlarged portion I l of the body is a threaded plug 25.

The body I0 is provided with a centrally disposed longitudinally extending opening 2t which is preferably square in cross sectional area and which has slidably mounted therein a pin 2l which is likewise square in cross sectional area and which extends upwardly and outwardly of the body Il and has affixed to its outer end an eye 28 to which, in turn, is affixed a cable 29. The passage 26 communicates at its lower end with the hollow interior` 30 of the enlarged portion II and forms a shoulder 3| therewith. The pin 2l has integrally formed with its inner end a. cylindrical extension 32 which is threaded, as

indicated at 33, at its lower extremity. A nut 34 is threaded upon such extension and a washer 35 is also mounted upon the extension adjacent the upper side of the nut 34. A compression spring 36 surrounds the extension 32 and bears against the shoulder 3| at its upper end and the washer 35 at its lower end. A transverse opening 31 extends centrally through the shaft I8.

An outwardly extending ear 38 is formed adjacent the upper end of the body I Il and has pivoted thereto a hook 39 whose outer end is adapted to engage in an opening 40 formed in one side of the rod 2l' adjacent its upper end. A tension spring 4I interconnects the hook 39 and an eye 42 formed at the upper end of the body I 0.

In operation, it will be apparent that normally the lower end 33 of the extension 32 of the pin 2 will be engaged in the opening 3'I in the shaft I8, the compression spring 36 acting against the shoulder 3| and washer 35 to maintain the pin 21 in such engagement, It will thus be apparent that the fluke assemblies, the housing assembly I2 and the body I0 will at such time remain substantially rigid with relation to each other. In this condition the device may be utilized in conventional manner as an anchor to engage a river bottom, sea bottom or the like, the ilukes 22 in such case being utilized in conventional inanner. When, however, it is desired to weigh the anchor forming the present invention,

the cable 29 is pulled upwardly by an operator positioned in the boat or ship with which the anchor is utilized whereupon the pin 2'1 will be drawn upwardly against the action of the spring 36 to thereby remove the extension 33 from the opening 31 thus freeing the body lil and shaft housing I2 so that they may revolve upon the shaft I8, or permit the shaft to rotate freely within the housing. In this condition the anchor forming the present invention may be more easily manipulated out of engagement with the sea bottom or the like as aforesaid, since the flukes 22 will now successively engage the bottom, causing the shaft I8 to turn in the housing I2 and permitting the entire anchor to thus be rolled toward the boat or ship by pulling upon the anchor cable I5. It will also be noted that as the pin 2l is drawn outwardly, that the hook 39 will be forced into engagement with the opening 49 by means of the tension spring 4I to thus maintain the same in an outward position without the exertion of further eiort on the part of the operator. The plug 25 may be removed for the purpose of introducing lubricant into the housing I2.

While but one form of the invention has been shown and described herein, it will be readily ap parent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
