Abstract: A water craft anchor primarily comprising a shank assembly, arm assembly, and housing. The shank assembly swively connects to the arm members at a predetermined location. The arm members having a common shaft fixedly mounted inbetween. The housing assembly is rotably mounted and partially houses the common shaft and a chain member connects the shank assembly to the housing.

Abstract: There is disclosed an anchor assembly comprised of a shank member on which are disposed cooperating fluke members which are rotably positioned on the shank member wherein each fluke member is formed with stabilizer portions capable of assuming a nestling relationship therebetween in deployed cooperation of the anchor assembly.

Abstract: An anchor construction for fishing and pleasure craft, especially those with a power anchor line winch, which includes a center swivel plate in a plane transverse to an anchor blade. The centerplate has a V-slot in which slides a clevis attached to an anchor line to effect release of a snagged anchor without moving the boat over or past the anchor. A stop lobe on the anchor blade cooperates with the center plate to limit relative motion.

Abstract: An improved boat anchor assembly including an anchor shank having a pair of penetrating flukes pivotally connected thereto and supported for angular displacement about an axis normally related to the longitudinal axis of the shank, motion limiting stops mounted on the shank for arresting pivotal motion of the flukes relative to the shank, said shank being provided with a pivotal coupling interposed between the ends thereof and a shear pin for imparting stability to the shank and adapted to give way under angularly applied loads of predetermined magnitudes whereby the shank is permitted to "break" for facilitating recovery of the anchor, and releasable coupling means including a single non-load bearing pin for releasably locking said flukes and said shanks into an integral configuration whereby the anchor readily may be disassembled for compact storage.

Abstract: An anchor in which the flukes pivot on the shank about independent axes wh converge toward the anchor chain end of the shank. Lugs at the base of shank provide for mounting the pivots. The anchor is reversible and has support plates on either side of its base which act as stops to limit the extent that the plate-like flukes can close toward each other as the anchor is set.

Abstract: A non-fouling fluked anchor having a yoke-like shank in which the yoke arms are arcuate and pivotally attached to a pointed, center mounted fluke such that the arcuate arms of the shank provide for variable positioning of the fluke point to insure initial penetration of the fluke point in sea floor bottoms having different degrees of hardness. The fluke tip, the yoke frame, and the anchor line tether establish a three point contact with the sea bottom. The arcuate yoke shank arms allow a variable initial penetration angle of the fluke from 15 degrees to approximately 67 degrees. As a relatively harder sea bottom is encountered the anchor, due to the action of the arcuate yoke will pivot to provide a steeper fluke angle to insure penetration. Once the fluke has penetrated the bottom the anchor will then assume the secured position at the conventional holding angle.

Abstract: A lightweight anchor in which each one of the flukes is made up of two sheets of stainless steel plate stock, stacked one on top of the other and welded together. Each sheet contains a plurality of integrally formed, longitudinally extending ribs and the inner and outer edges of each sheet are bent to form upwardly extending perpendicular flanges. The crown is a generally U-shaped member made out of stainless steel plate stock. The angle of rotation of the shank relative to the flukes is limited by a pin connected to the shank and extending into angular slots in support plates attached to the flukes. A pair of stainless steel U-shaped braces made out of bar stock are rigidly connected to the flukes to prevent yawning movement of the flukes and also serve as a back up mechanism for limiting the angular movement of the shank relative to the flukes. All the surfaces on the anchor are electropolished.

Abstract: An anchor construction wherein two pairs of independently operating flukes are pivotally mounted at one end of an elongated shank. Each fluke of the primary pair of flukes lies on an opposite side of the shank and each fluke of the secondary pair of flukes lies on an opposite side of the primary flukes. Means are provided to simultaneously establish a relatively small angle between the primary flukes and the shank and a relatively large angle between the secondary flukes and the shank. This capability permits the anchor to be used interchangeably in either hard or soft bottom sediments without human intervention to reset fluke angles.
