Abstract
An automobile-tire snow chain comprises running chain sections connected between a closed outer annular maintaining chain and an open inner maintaining chain. A long chain section is connected at one end to a first ring on one end of the inner chain and is looped through a second ring on the other end of the inner chain and through the first ring, so that the inner chain can be closed by pulling on the long chain section to tighten the loop. This long chain section includes a running chain portion which passes over the tire and is secured to a buckle on the outer annular chain, the free end of the long chain section being threaded about the outer annular chain and secured by a tensioning spring and a buckle.
Claims5
An automobile tire snow chain, comprising;
- an open side chain for one side of a tire, the chain having two ends;
- a closed side chain for the other side of the tire;
- a series of several tread chains connected to the side chains and uniformly angularly spaced apart along the open side chain, in use;
- and
- a combined special tread chain and chain-securing device, comprising an additional chain having a first end connected to one of the ends of the open side chain and having a hooking device at a second and free end of the additional chain, the additional chain passing through the other end of the open side chain and also through said one end thereof to provide a loop connecting the ends of the open side chain which loop can be tightened by pulling the free end of the additional chain to close the open side chain, and the additional chain having, adjacent and extending from said one end thereof, a chain portion which in use passes over the tread of the tire providing a special tread chain circumferentially spaced from adjacent ones of the several tread chains, the free end of the additional chain being held, by securement of the hooking device, to the closed side chain;
- whereby the several tread chains and the special tread chain portion of the additional chain are uniform tractive elements on the tire.
