  • Patent number: 4995566
    Abstract: A reel for a chain or the like comprises a core portion adapted to have a chain wound around it and a pair of flange portions arranged at opposite ends of the core portion for retaining the chain on the core portion. The core and flange portions are constituted by a plurality of bent rods bonded together. Each of the bent rods comprises a central portion forming part of the core of the reel and a pair of side portions at its opposite ends forming parts of the chain-retaining flanges of the reel. The reel is inexpensive to manufacture, and can be dipped in rust-preventive fluid along with the chain, thereby eliminating the necessity of winding a chain onto a special reel for rust treatment and then rewinding the chain onto another reel for storage or shipment.
