ABSTRACT:
An assembly is provided for raising and lowering, and for firmly securing, a type of anchor known as a "Bruce" anchor. The assembly includes the rear channel shaped section for receiving the shank of the anchor when it is stowed, and for mounting the assembly on the front deck of the boat. The assembly also includes a forwardly extending section having two side plates which have a roller mounted between them for raising and lowering the anchor over the front portion of the deck of the boat. The roller may be of high strength plastic such as Delrin, and is fairly large, being in the order of 5 inches in diameter and about 3 or 4 inches in width and deeply grooved to receive and center the chain or rope by which the anchor is raised and lowered, and also for engaging the L-shaped shank of the anchor when it is stowed. The front portion of the assembly also includes two protrusions for engaging the fluke area of the Bruce anchor. In addition, the roller is mounted for movement upwardly and to the rear, as the anchor is pulled up and into the assembly with the main shank of the anchor extending along the channel shaped rear portion of the assembly, so that the anchor is held firmly by the protrusions, and the engagement by both the main portion of the shank and the forward or crown portion of the shank with the roller, as the roller shifts upward and to the rear.
