Abstract: A traction device includes a series of elastomeric traction elements adapted to the circumference of a tire of an automotive vehicle. Each traction element has a substantially U-shaped elastomeric body, a plurality of reinforcing wires arranged in parallel and embedded in the elastomeric body along the lengthwise direction thereof, cross bars also embedded in the elastomeric body and integrally connected to opposite ends of the reinforcing wires at substantially right angles therewith, and a plurality of openings formed through the elastomeric body adjacent to the inner edges of the cross bars. Metal fasteners extend through the openings and are anchored to the traction element and connect the latter to ropes to be disposed at both side circumferences of the tire.

Abstract: A vehicle wheel anti-skid attachment having cross chains interconnecting tread portions of inner and outer side wall plates. Rim portions of the plates are interconnected by a tensioning mechanism part of which is threaded through a wheel opening to extend over the wheel rim. The mechanism includes a hand-turned shaft accessible from the outer face of the wheel and operable to apply the required tension to the cross chains.

Abstract: Anti-skid assembly adapted to be removably mounted on a tire. The assembly includes a plurality of deformable transfer straps adapted to be mounted on the surface of the tire by a releasable anchoring structure. The straps are adapted to normally rest relatively flat against the surface of the tire and to be shifted to a substantially perpendicular position when the tire skids with respective road surface to increase the frictional and mechanical engagement with the road surface and to return to the normal flat configuration against the tire surface after leaving engagement with the road surface. The anchoring structure includes braided cables which are parted to accept fasteners connecting the straps to the cable. Studs can be provided on the transverse members. A quick acting latch structure is provided to hook and unhook the braided cables.

Abstract: Improved traction arms for vehicle anti-skid devices. The rollers or traction segments of the arms are mixed in size of outside diameter or provided with interior tipping bevels or both to give more traction.

Abstract: Traction augmenting ribs are formed of a semi-rigid material particularly well-suited for placement around a vehicle tire or the like. Each rib is formed of a pair of side arms and an interconnecting central portion which are arranged in a generally U-shaped configuration to fit around the vehicle tire. The side arms are formed of a bow-like spring arrangement which is flexible in response to application of forces at the ends thereof in a radially inward direction relative to the tire so that the side arm ends are positioned to displace the rigid interconnecting elements beyond the contour of the tire. Interconnecting linkages or cables are passed through the rib ends and are tightened in a circumferential direction so as to apply the radially inward force to the rib side arms. Reinforcing steel wires can be included throughout the length of each rib and reinforcing crossbars can be embedded within the central portion of each rib so as to facilitate accommodation of tires of varying tread widths.

Abstract: The device is for attachment to a vehicle tire to improve traction on ice or snow. The device is constructed from a circumferential segment of preferably a used tire and includes a plurality of studs extending through the tread area of the tire, one end of each stud for interlocking with the tread of the vehicle tire and the other end of the stud for gripping. In an alternate embodiment, the used tire segment is from a studded snow tire and the studs are maintained in the tire with internally extending studs being added for interlocking with the tread of the vehicle tire.

Abstract: Anti-skid means for front or rear vehicle tires comprising shoes of pliant material around the tire held in place by lengthwise chains terminating in hooks lying against the outer and inner side walls, which shoes are one-piece with a ribbed and textured central portion for the tread and sides and means for removably holding the shoes and associated shackles in place during rotation of the wheel of the vehicle. The parts are specially designed to give good traction and comfortable riding qualities on icy and snowy surfaces with reduced wear.

Abstract: An annular meshwork to cover the tread and part of the sidewalls of a tire includes a plurality of flexible, nonstretchable strands extending around the tire, each strand being connected to adjacent strands at spaced apart points to form an annular meshwork or network to improve traction and steering. The sides of the meshwork are defined by end rings, at least one of which is extensible, e.g., elastic, to allow mounting on the tire. The strands adjacent the end rings are fixedly attached to the end rings. The meshes are formed by the strands with a significantly longer dimension in the circular direction of the annular meshwork than in the transverse direction. The connections can be made using clamping devices of which specific embodiments are disclosed. The clamping devices can be provided with a protective layer on the tread-facing (inner) side. The outer side can be provided with projections in the nature of short spikes to enhance traction.
