The invention relates to anchors and has among its various objects the production of a construction whereby the holding action I of the anchor is released when a predetermined resistance is applied to the holding arms of the anchor.

Another object of the invention is to pro- Vide means whereby the holding action of the anchor may be manually re eased, and

10 also to provide a construction which is both automatically and manually operable to effeet a release of the anchor from the element with which it is in holding engagement.

A further object of the invention is to ro- 15 vide a construction in which the hol ing arms may be arranged at an angle to another element of the structure and be moved to a position transverse to the angular position,

to thereby arrange the arms so that they 20 will release the element with which they are in holding relation and be arranged to prevent the possibility of engagement with an obstruction or object, as the anchor is withdrawnfrom the water. The invention has 2 these and other objects, all of which will be explained in detail and more readily understood when read in conjunction with the accompanying drawings, which illustrate one embodiment of which the invention is susceptible, it being understood that various changes and modifications may be resorted to without departing from the spirit of the appended claims, formin a part hereof.

In the drawings, ig. 1 is a perspective view of an anchor constructed according to one embodiment of the invention;

Fig. 2 is a longitudinal section of the device shown in Fig. 1, showing the arms in extended and retracted position;

Fig. 3 is a section taken on line 3-3 of Fig. 2; and

Fig. 4 is a perspective view of certain portions of the structure shown in Fig. -1 on a sli htl enlarged scale.

11 t e particular embodiment of the invention illustrated in the drawings, the use of a body member is contemplated, the body providing means for supporting a lurality of arms 11, which arms are pivote as at 12 to the body portion 10. These arms are adapted to be arranged in angular or radial relation and transverse thereto to thus arrange the arms so that they may grapple or engage an object to hold the anchor against relative movement and be moved from the angular or radial relation to a osition in which said arms are substantia y parallel with the body portion 10, in which latter position of the arms, the anchor may be released from holding engagement with said object and be withdrawn from the water Without liability of engagement of said arms with obstructions as the anchor is drawn through the water. The bodylO is provided with a centrall arranged longitudmal bore 05 13, that end 0 the bore adjacent the arms is enlarged as indicated at 14. to'provide a housing for a coil s ring 15, WhlCh reacts between one termination of the enlargement 14 of the bore and the head or enlargement 16 provided upon the reciprocable .element 17-. The reciprocable element 17. is provided with an opening 18 through which a cord or cable may be passed to complete a connection between the anchor and an object located above the surface of the water. It will be noted, that each of the arms 11 has an extension 19 which projects inwardly from the pivot 12 thereof, into engagement with the head 16 of the reciprocable element 17 which will thus cause the action of the spring to be transmitted to the arms 11 to hold them in a. radial or angular position and a position transverse thereto. The body 10 is provided with a plurality of stops 20 to respectively engage the arms 11 and limit both outward and inward movement of said arms.

.It will be noted that from an inspection of Fig. 2, that when the arms 11 are in an extended position, the head 16 of the reciprocable element engages with the ends 19 of the arms 11 which causes the arms to engage the stops 20 which limits the action of the spring 15, movement of the arms and holds the arms 11 in the radial or angular position. 95

It is also evident from an inspection of Fig. 2, that when the arms 11 are moved to the dotted line osition, the head 16 engages As before stated, the structure is operable to permit movement of the arms 11 from the radial or angular position thereof, to the dotted line position thereof shown in Fig. 2 and that the arms maylbe moved to the last mentioned positlon e1t er automaticall or manually by the application of a pu ling force applied to the reciprocable element 17 or the application of a resistance applied to the arms which resistance is in excess of that offered by the spring 15. It is evident, that when the arms are arranged in the full line position shown in Fig. 2, that said arms may engage an obstruction to thereby secure the anchor. It is further evident that when a resistance is a plied to the arms which is in excess of the orce applied by the spring to hold the arms distended, said resistance is applied by said arms to the head 15 which will compress the spring and thus allow the arms to pivot and be moved against the action of V the spring, until the assume the dotted line posltion shown in ig. 2 after which the spring 15 again-acts upon the ends 19 of the arms to hold the arms in said last mentioned position, thus releasing the anchor from holdmg engagement and allowing the anchor to be withdrawn from the water.

It is further evident, that should the device fail to operate in a manner just described, that the arms 11 may be released to assume the dotted line posltion shown in Fig. 2 through the agency of a manually operated means which includes the reciprocable element 17 and a cord attached thereto. It is manifest when the arms are distended that they may be arranged in a retracted position through the agency of a pulling force applied to the cord.

As before stated the cord is attached to the reciprocable element 17, and thus means is provided for actuating the device to accomplish release of the arms when an obstruction 1s encountered which, for some reason does not accomplish the actuation of the device in the manner explained. To effect a release of the device when a situation such as that just referred to is encountered, the reciprocable element 17 is, through the agency of a pulling force, applied by the cord moved to compress the spring 15 which will release the head 16 from engagement with the ends 19 of the arms which frees said arms and allows said arms to freely move from their angular or radial plosition to one in which they are substantia y parallel to the remainder of the structure. Of course, after the anchor has been released, the head 16 will a ain engage the rounded extensions 19 of the arms 11 and hold said arms in the dotted line position reciprocable element 17 the trolle having a Wei ht and a fish-line with hoo secured to t e line, the line being raised and lowered relatively to the water by drawing the pulley along the cord or cable. It 1s mamfest that the structure is one which will insure agamst loss of the anchor, provided the cord or cable 18 which is attached to the reciprocable element 17 is of suflicient strength to overcome the resistance of the s rin 15.
