2 Claims.

My invention relates to anchoring devices and has among its objects and advantages the provision of an improved anchor, including means for rendering the anchoring arms inoperative for holding purposes when a pre-determined pulling force is applied to the line connected with the anchor.

In the accompanying drawing:

Fig. 1 is a plan view of the anchor showing the holding blades folded;

Fig. 2 is a sectional view along the line 2-2 of Fig. 1;

Fig. 3 is a sectional view along the line 33 of Fig. 2;

Fig. 4 is a sectional view along the line 4-4 of Fig. 2; and

Fig. 5 is a sectional View along the line 5-5 of Fig. 2.

In the embodiment selected to illustrate my invention, I make use of a tubular body 10 comprising sections l2. These sections include flanges I 4, arranged in overlapping relation, and provided with openings for the reception of rivets I6 for firmly connecting the sections together.

The opposite end of the housing I0 is closed by means of a cap l6, the flange 18 of which embraces the outer wall of the housing. A/rivet 26 passes through openings 22 in the housing, and slots 24 in the flange [8 for holding the parts in assembled relation.

A plurality of holding arms 26 is pivotally connected with the housing l0. Slots 28 are provided in the housing for receiving the ends 30 of the arms 26, which ends are arranged at right angles to the major positions of the arms by bending the latter.

On the outer surface of the housing I6 I weld a plurality of straps 32, each having both ends bent to provide flanges 34. These flanges are 4.0 grouped in pairs adjacent the slots 28 and are spaced for freely receiving the ends 30. Rivets 36 pass through aligned openings in the grouped flanges 34 and the ends 30 to provide pivotal mounting for the arms 26.

In Fig. 2, the full line position of the arms 26 illustrates the holding position of the arms while the dotted line position illustrates the shifted position of the arms for releasing the anchor. Within the housing [6, I mount a pistonlike member 38 which is circular in cross-section, and arranged to move freely within the housing. This member is provided with a transverse slot 46 for accommodating a rivet 42 fastened to the sections I 2 for additionally connecting the sections into 5 a unitary whole.

One end of the member 38 is arranged to bear against the ends 30 as indicated at 44. Means for holding the member 38 in the full line position of Fig. 2 comprises two arms 46, having their ends 48 arranged to engage the member in the manner 5 illustrated in Fig. 4. 1

Each arm 46 comprises two spacedv flanges 50, connected by crossbars 52. One of the arms 46 is offset, as at 54, to accommodate the other arm which passes therethrough. The two arms are 10 pivotally connected by a shaft 56, which passes through a slot 58 in a releasing bar 60 and has its ends riveted to the housing [0 (see Fig. 2). Links 62 are pivotally connected with the arms 46 at 64 and with the bar 60 at 66. The bar 52 15 at the upper end of each arm 46 is connected with the lower bar 52 of the other arm by a tension spring 68. These springs operate to normally hold the arms 46 in the full line position of Fig. 4.

The bar 60 slides freely through the openin H1 in the housing I0. With the arms 46 in the full line position of Fig. 4, the member 38 is firmly held in the full line position of Fig. 2, at which time the arms 26 are positioned for anchor purposes. The arms 26 are latched against pivotal action. The ends 36 are recessed at 12 to provide fingers 14, which engage the inner face of the flange 18, for limiting the pivotal action of the arms. The member 38 holds the finger l4 firmly against the flange l8.

I provide the bearing 60 with an opening 16 for connection with a line. The springs 68 resist forces applied to the line attached to the bar, but when the forces exceed a predetermined value, 35 the arms 46 will be shifted to the dotted line position of Fig. 4 for releasing the arms 26. I provide the member 38 with a bore 18 for receiving the arms. Outward movement of the bar 46 relatively to the housing Ill shifts the links 40 62 in such a manner as to pull the upper ends of the fingers inwardly, thus shifting the lower ends of the arms towards the center of the housing.

In the latched position of the arms 26, the 4:5 rivet 42 lies adjacent one end of the slot 40, as indicated in Fig. 4. When the arms 46 are shifted to the dotted line position, any pull on the anchor will shift the arms 26 to the dotted line position of Fig. 2, at which time the member 50 38 is shifted to the dotted line position of Fig. 4 with the lower ends of the arms 46 lying within the bar 18.

In the dotted line position of the arms 26, the ends 30 are in abutting relation with the housing II), as indicated at 80. The arms 26 are arranged to be folded against the housing In in the manner illustrated in Fig. 1. The flange I8 is provided with slots 82 which may be aligned with the slots 28 for freeing the fingers 14. Referring to Fig. 1, the slots 24 permit the cap Hi to be rotated about the housing III for aligning the slots 82 asshown. The collapsible feature permits the anchor to. be folded compactly for handling and transportation purposes. The. bore 18 is flared at 84 toprovide a gentle curvature facilitating shifting of the arms 46 to a position within the bore.

My invention provides an ideal anchor fortrolley lines employed for fishing purposes. The device may be used with equal advantage as anchor for other purposes. The amount of pull required for releasing the anchor depends upon the tension of the springs 68;. 1

Without further elaboration, the foregoing. will so fully describe my invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of. service.

I claim:

1. In an anchor, at supporting body having a plurality of anchoring arms pivotally connected therewith, an arm holding member movably associated with said supporting body and arranged for holding the arms in an anchoring position,

a pair of arms pivotally connected inwardly of their ends, one end of each arm being arranged to engage said member for holding the same in fixed relation with the anchoring arms, links pivotally connected with the other ends of said arms, a spring connecting one end of each arm with the opposite end of the other arm, and means movably connected with one end of each arm and actuated when a predetermined force is applied thereto for shifting the arms to a non-holding position with respect to said member.

2. In an anchor, a tubular body having anchoring arms pivotally connected therewith, a member slidably positioned within the tubular member and cooperating'with the anchoring arms for holding the same in an anchoring position, said member being provided with a bore, means for holding the member in a fixed position, said means comprising a plurality of arms pivotally connected together, a linkage for moving the arms to different positions, said arms being arranged to engagev one end of said member for holding the same against shifting, said arms being arranged for shifting to another position for reception by said bore to permit shifting of the member...
