  • Patent number: 5009256
    Abstract: A tire traction device for vehicle tires includes a pair of rope-like side cord members for circumferential placement on the sidewalls of a tire, and a series of wire rope cross cords which interconnect the side cords and extend across the tire tread. The cross cords are connected to the side cords at knotted connections, and a ferrule is attached to the ends of each cross cord outside of each knotted connection to prevent the cross cords from disconnecting from the side cords. Coil spring rollers are supported on the cross cords to provide additional traction. Each cross cord also supports a pair of tubular spacers located inside and adjacent the knotted connections to maintain the rollers in the center of the cross cord. One end of each side cord is knotted into a series of male connector knots while the opposite end of each side cord is knotted into a female loop knot for selective interengagement with one of the male connector knots to join the opposite ends together about a tire.
