Abstract: Metal cross chains are interconnected on the inboard side by an inboard rope connector and on the outboard side by an outboard rope connector. Each interconnection of a rope connector with a cross chain includes a combined rope-to-cross chain connecting link and rope clamping ring and rope connector adjustment device having a substantially V-shaped wire body with a loop formed at each end of the V. One of the end loops is firmly clamped to the rope connector and the other one of the loops partially surrounds and slidably engages the rope connector and is open sufficiently to permit the rope to be slipped out of that loop. A collar is clamped to the rope at a position to maintain a loop in the rope between the two connecting link loops when the collar is inside the slidably engaged loop, and to permit the rope loop to be released when the collar is positioned outside of the slidably engaged connecting link loop.

Abstract: A plurality of metal cross chains are provided which are interconnected with one another by means of inboard and outboard rope connectors. Various means are provided for adjusting the size and determining the tightness of the tire chain structure when assembled on the tire, such as a plurality of removable crown loop length adjustment devices each comprising a helix of metal wire retained by a hinged retainer lever mounted upon U-loops in the rope connectors.

Abstract: An improved tire chain assembly of the type having adjustable inboard and outboard rope straps has link chains which extend at intervals between the straps, and includes a series of adjustment clamps on the rope straps whereby the assembly is securely but releasably engaged on a wheel.
