Highway safety tire device

Claim 1

In a highway safety device for use as a barrier on a roadway, the combination of, at least three full-scale used motor vehicle tires concentrically arranged and adapted and stacked to form an elongated, cylindrical, integral columnar body having an elongated, concentric, cylindrically outlined opening formed by the inside rims of said stacked tires, concentric outside completely cylindrical walls defined by the treads of said tires, and transverse completely circular sidewalls connected between said rims and said tread, said sidewalls having circular convex portions thereof each contacting the circular convex portion of the tire adjacent to it, walls defining bores formed annulary and axialy in the side walls of said tires generally at the point of tangency thereof, said bores aligned with each other so that when said tires are stacked said bores define at least two axial oppositely spaced openings through said side walls, and fastening means operable to fixedly fasten said tires integrally together in shock resistant relationship to each other through said connected sidewall circular portions only of said sidewalls for leaving said concentric opening entirely free of obstruction, said fastening means including a plurality of rigid elongated fastening members egaging said bores and elongated, one-piece spacers engaging the sidewalls of said tires adjacent said elongated members in opposed tensioned relationship to said elongated members to maintain said stacked tires in rigid spaced shock resistant relationship to each other.
