Abstract: There is disclosed in the specification an improved tire chain including at least one pair of tire gripper portions adapted at one of their ends to exert pressure on the tire at the tread of the tire, and at the other end on their respective sidewall near the rim of the tire. Such tire gripper portions are adapted to grip the tire independently, but by themselves do not have strength to resist the rotational forces of the tire.To add to the traction of the tire, and hold the individual tire gripper portions on the tire during rotation, a pair of connecting chains is employed between the two tire gripper portions. To resist disengagement from the tire during rotation by centrifugal force, a pin portion is provided on the inner end of each gripper portion which is adapted to press into the tire to a predetermined stop so that such pin portion is actually embedded in the sidewall of the tire. It is disclosed that such pin portion could also engage a preformed recess in the sidewall of the tire.

Abstract: Vehicular road traction apparatus feeds a traction portion of an endless chain between a tire and the road surface and a recirculating portion of the chain is picked up aft of the tire and fed into a conduit which conducts it back to a point fore of the tire where it is fed continuously under the tire as the traction portion. The conduit is supported in position by arms and pivot pins so that the conduit may be moved between the aforesaid feeding position to a non-feeding position where the chain is held away from the tire. A cable moves the conduit between the two positions. The conduit may be hinged midway in its length so as to move its feeding and pick-up ends farther apart to stretch the chain taut in the non-feeding position. The conduit may be located outside or inside the tire. When located inside the tire, a skid plate and guide bar assist the supporting means to locate the feeding end of the conduit in proper feeding position.
