TIRE CHAIN INSTALLATION TOOL FOR DUAL WHEELS

摘要

A tool is provided for installation of tire chains on the dual drive wheel assemblies having wheels with openings therein. The tool comprises a central elongate projection having a tool restraint opening at its inner extremity which is adapted for registry with two of the wheel rim openings and receives an implement extended through the wheel rim openings for establishing an interlocked relation between the wheel rims and the tool. A pair of generally U-shaped side projections are formed integrally with the central projection and extond in diverging rotation and in opposed aligned directions. Each of the side projections are provided with chain positioner elements adapted to extend radially inwardly along the side wall of the respective tire. The tool is provided with a central chain connector and said side chain connectors to which the central and side chain rails of the tire chain are attached respectively. The chain connector elements cause the tire chain to be wrapped about the dual wheel drive upon one revolution of wheel movement after which the tool is removed and the ends of the tire chain rails are locked in assembly for use.
