  • Shellfish dredge chafing gear
    Patent number: 4349972
    Abstract: A device for protecting shellfish dredge chain bags, featuring arcuate strips of reinforced rubber adapted to be attached to trail beneath the bottom side of the bag to cushion and separate the bag from abrasive action against the ocean floor when it becomes weighted with rocks and shellfish. These strips, in curved form, are cut from the tread or side wall portions of used vehicle tires and are attached to the chain bag in a manner that protects the forward edge and corners of the strip from catching on the ocean floor while allowing the longer portion of the reinforced rubber strip to trail beneath the chain bag. An array of closely adjacent strips effectively defines a wear-resistant surface of the chain bag.
