Abstract: A winching and traction intensifying device for extricating an immobilized rubber tired vehicle. The device has a traction intensifying portion secured to a driving tire and an anchoring portion connected to the traction intensifying portion. A corresponding non-driving tire secures the anchoring portion through the weight of the vehicle itself to establish a necessary fixed point for the winching device while, simultaneously, the traction intensifying portion is coupled to the driving tire.

Abstract: Chain links for anti-skid chains, integrating cross chain end attachment with side member sections is disclosed. Fastening devices attached to opposite ends of the inner side member and extended to the outer side member thereby forming an additional cross member is provided. Leader devices for the extension are also disclosed. Binder devices for the outer side member are disclosed. A flagging device for chain orientation is further disclosed.

Abstract: A tire-chain assembly for a vehicle-mounted wheel basically comprises annular inner and outer holders respectively engaging the inner and outer faces of the wheel. At least one traction chain crisscrosses over the road-engaging surface of the wheel between the two holders. The inner holder is of variable diameter, so that it can be fitted over the tire and then have its diameter decreased to allow the traction chain to be tightened on the wheel. Mechanism on this inner holder is connected via a flexible element that passes over the road-engaging surface of the wheel to the outer face of the wheel so that a pull on this mechanism will reduce the diameter of the inner holder and tighten the chain assembly on the wheel. The outer end of this flexible element, which may be a chain, is then secured to the holder on the outer surface of the wheel.

Abstract: An anti-wheel spin device for rubber tired vehicles including a pair of mattings or pads of different lengths coupled together to prevent them from propelling against the vehicle by a spinning wheel. A winching accessory is also provided for securing one of the mattings or pads to a wheel to be extricated when the force required to move the vehicle exceeds the tractive force developed between the matting or pad and the wheel.

Abstract: A small chain for a vehicle tire has an inner chain member adapted to lie along a flank of the tire and of a circumference substantially equal to the circumference of the tire in the region at which this inner chain member lies, the ends of the inner chain member having a hook and an eye for mutual engagement.An outer chain is composed of two chain members which are interconnected by a hook and eye, the outer chain having a length in excess of the circumference of the tire in the region in which the outer chain lies thereagainst, the end of one member being formed with an eye and the end of the other member of the outer chain having an S-hook. The inner and outer chains are bridged by two sections of transverse chains linked to the inner and outer chains over the entire circumference of the tire.

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.

Abstract: To improve the mounting and handling of tire chains there is provided a device which easily and quickly can be attached and dismantled by anyone without tools. The device comprises two attaching bars whereby the first bar is fastened to a gripping element with an eye on each side and the second one is fastened to a gripping element with an eye and is formed with a hook on the other end, turned in 90.degree.. The hook is hooked around the first bar, slips down toward the eye and the device is attached.

Abstract: A tire traction apparatus for use on a tire comprising at least one chain having first and second ends and a length slightly greater than the circumference of the tire, a latch for securing the first end to a portion of the chain proximate the second end, and a plurality of generally U-shaped members affixed to the chain at spaced-apart intervals, the members including a tire tread engaging base portion and a pair of opposed tire sidewall engaging portions, the chain serving to provide improved traction on ice, the base portion serving to provide improved traction on snow, and the tire sidewall engaging portions serving to maintain the chain on the tread.
