This invention relates to improvements in anchors of the'kind which'include an elongated shank to which the hauling line is connected. More particularly the invention is concerned with an anchor of'the type in which the connection between the hauling line :and the anchor is through the medium of a runner which is loosely mountedupon the shank and which is movable thereon, as occasion may require, to either of twopositions, in one of which engagement of the flukes of the anchor is facilitated and in the other of which disengagement of the flukes is facilitated. 1 Heretofore it has been the practiceto construct the anchor in such a manner that the runner is free to move in either direction,

the shank owing to its weight overbalancing the anchor when the runner is in the position at which the force which is appliedto the ac hauling line can be most effectively trans mitted to the anchor. i It frequently, howevenhappens that owing to the firmness with which the flukes are engaged or embedded, it is necessaryto apply a greater-force to the hauling line than is normally necessary. The resistance; to disengagement which is thus offered by the anchor is, in many instances, greater than can be overbalanced by the shank. The free end so of the latter, therefore, moves toward a vertical or upright'position thereby permitting the runner to move awayfrom' the position in which it must remain in order to facilitate disengagement of the flukes. The pur- The principal object of the present invention is to overcome the above objection, this object contemplating the locking of the runner that point onthe shank at which the 4 force which is applied to the'hauling line can be most effectively transmitted to the anchor.

The invention is illustrated in the accompanying drawing in which:

Figure 1 is a side elevation of an anchor embodying features of the invention. Figure 2 is a top view of the anchor.

Figure 4 is a fragmentary section taken along line. i4 of Figure 3.v I 9 932. Serial'No. 619,396.

t Figureii is an enlarged fragmentary secformed or provided with suitableflukes 8.

Inorder to facilitate engagement of the fiukes, the shank .7 is preferably pivotally connected 'tothe body 6 so as to permit the 'latten under the influence of gravity, to as- .sfume positions at an angle to and at either side of the shank. To this end the shank 7 is formed or provided at one end with a ball 9 which fits loosely within a socket 10 formed in. the body, the ball beingheld in the position described bya pin ll which is secured at its ends in opposite walls of the socket.

T heshank 7 extends through anarouate slot influence of gravity, pivots on the ball 9 and the 'flukes, are presented for effective engage- :ment. The range of movement of the latter isdetermined-by the end walls 13 of the sl0t-12. 1

.Theianchor may be connected to a suitable hauling line 14: (Figure 1) through the agency of a runner 15-. The latter includes a clevis 15 which. fitsloosely upon the shank and which is'freely movable thereon between the body 6 and a ball head 17 the latter being formed or provided at the free end of the shank; When the flukes of the anchor are engaged the runner, 15 is preferably positioned at the free end" of the shank 7 that is to say against, or in the vicinity, of, the

head 17 The runner is preferably arranged in this manner prior to dropping of the anchor in order'to facilitateengagement of the flukes. l/Vhen weighing anchor the runner is moved until lt s arrested by the body 6 that isto say, it is moved from the position s own 7 in dotted lines in Figure l to the position shown in, full lines. This may be convenient.- ly efiected by causing the boat which carries .12 which is formed in the head between the ,flukes and transversely of the plane occupied byqthe latter, whereby the body, under the the anchor to move in the direction opposite to that in which it tends to drift. 7

Heretofore it has been the practice indesigning anchors of the type generally described to so balance them that when the runner moves against or in the vicinity of the head of the anchor and a force normally adequate to free the anchor is applied to the hauling line, the head of the anchor will pivot about its connection with the shank and free itself. It frequently happens, however, that the flukes of the anchor become so firmly engaged or embedded that a greater degree of force than normal is required to free them. Hence, in such a case the balance of the anchor is overcome and the free end of the shank is pivoted with respect to the anchor head instead of the latter being pivoted with respect to the shank. The. runner, therefore, moves toward the free end of the shank, thereby rendering disengagement of the flukes more difficult, if not impossible.

' In order to overcome this objection the invention contemplates the locking of the run ner upon the shank in the vicinity of the anchor head so that as the hauling line is drawn in to weigh anchor the runner maintains its position and the head 6 pivots on the ball 9 to free itself despite the degree of force which is required to accomplish this.

To this end an element 18 is pivotally mounted between the arms of the clevis 16 upon a pin 19. The element is supported in such relation to the shank that one end thereof may be moved into and out of engagement with the shank. At its opposite end the element 18 carries a ringlike clevis 20 which is pivotally connected to the element by a pin 21 and to which the end of the hauling line 14 may be suitably secured. The runner is freely movable upon the shank between the anchor I head and the free end of the shank. Hence it may be positioned at the free end of the shank when dropping anchor and when preparing to weigh anchor it can be moved to the opposite end of the shank in the usual manner.

From the foregoing it will be apparent that disengagement of the flukes of the an chor is facilitated despite the degree of force which must be applied to the hauling line to accomplish this, the runner being automatically secured on the shank at the point at I which the force that is applied to the hauling line is most effectively transmitted to the anchor.
