ABSTRACT:
A new and improved apparatus for tightening a chain installed on a tire that is mounted on a wheel of a motor vehicle includes a hub assembly and a plurality of tension assemblies. Each tension assembly includes a first end for connecting to the hub assembly, a tensioning element connected to the first end, and a second end connected to the tensioning element. The second end is connected to a portion of the chain, such that the hub assembly and the tension assemblies exert tension on the chain in a radial direction toward the hub assembly. More specifically, the tension assemblies are attached to the hub assembly and the chain in pairs, and the tension assemblies of each pair are arranged in opposed relation. That is, the first ends of each pair are in opposed relation with respect to the hub assembly, and the second ends of each pair are in opposed relation with respect to the chain. At least one of the tension assemblies further includes a threaded shaft movable within a sleeve. The hub assembly contains a quantity of a de-icer liquid which is dispensed through a portion of the sleeve. A metering valve connected to the threaded shaft allows the metering of the de-icer liquid to be adjusted.
