Abstract: An assembly securely mounted to a wheel of an automotive vehicle to provide continual availability of cleats to be fitted around the treads of a tire for use in driving an automotive vehicle through mud or snow. The assembly consists of a cylindrical plate with a series of round through holes for affixing to a range of automotive wheel configurations with elongated lug nuts and bolts, a series of L-shaped brackets securely affixed around the outside perimeter of the mounting plate, a spring-loaded telescoping shaft extending from each L-shaped bracket parallel to the outside of a vehicle tire, a cleat affixed on the outside end of each telescoping shaft, so that each cleat can be locked in position around the tire treads with the telescoping shaft in the telescoping position and with each cleat further being placed in a locked position near the side of the tire when the telescoping shaft is in a retracted position so as to be out of the way when not in use.

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: Method and apparatus for providing selectively engageable and disengageable traction surface, on the periphery of a vehicle wheel by means of an apparatus mounted to a fixed portion of a vehicle, selective positioning of a journalled outer portion of the apparatus to engage and rotate with the outer, or tire, portion of the wheel, or, alternatively, to retract to a stored inactive position. The apparatus further provides for positive deployment with spring-loaded extension pressure, accommodation of localized variations in diameter and resilient mounting of traction bars.

Abstract: A device for improving the traction of the wheels of a vehicle in the presence of snow and ice on a road surface, said device including a series of spikes arranged on the exterior periphery of the wheel in contact with the tread of the type with the spikes connected to the hub of the wheel.

Abstract: A non-skid device in which the road engaging part is a long flexible member formed of one or more twisted steel wire cables embedded in a thick coating of rubber and in which said road engaging part, when on a tire, extends back and forth zigzag fashion diagonally across the tread of the tire and is secured in place on the tire by two belt type anchor members which are positioned respectively at opposite sides of the tire. The anchor member at the inner side of the tire has readily detachable parts which, when detached, allow the non-skid member to be applied to a tire from the outer side of the wheel without using a jack to lift the wheel. Means is provided for tightening the non-skid device on a tire after it is applied thereto. The flexible zigzag road engaging parts have good non-skid qualities and have longer life than metal cross chains when used on bare pavements.

Abstract: An auxiliary tire traction device for use with vehicle tires to provide increased traction when dictated by road or other conditions wherein the device may be detachably secured to the tire to increase contact and driving force for the vehicle.
