Abstract: Speed bumps for mounting across roadway lanes to encourage vehicle drivers to slow down are formed of laminated layers of elongated flexible rubber strips secured together to form a speed bump unit. Typical bump heights of three inches are obtained from six laminated half-inch layers. in one embodiment, layers not exceeding five inch widths cut from treads of discarded vehicle tires between opposing shoulders have a propensity to lie flatly upon a road surface, and are pyramided upwardly by a plurality of stepped layers of decreasing widths thus presenting inclined leading and trailing edges for intercepting the tires of oncoming moving vehicles. In another embodiment curved layers of tire tread strips form ingress and egress edges inclined gradually downward from an uppermost crown to the roadway surface for intercepting the oncoming moving vehicle tires.

Abstract: This invention relates to floor mat units made from single layer tread strips cut from discarded tire carcasses having attached thereto a web layer on a tread strip surface opposite to the tire tread and their method of manufacture. These mat units have a flexible, resilient, skid-proof and easy to walk on tire tread surface of long life which can bear heavier loads and longer life when constructed of steel belted tires, which provide convenient and low cost internal reinforcement wires. In different embodiments, the web strip is formed from either flexible plastic or fiber glass web material or from wire mesh stiff webbing material. The mat units comprise at least two side-by-side layer strips of tire treads secured on a mesh sheet, and thus can be constructed in various sizes and aspect ratios. For example parquet nine inch by nine inch type floor tiles have two four and a half inch strips, nine inches long attached to a nine inch by nine inch web sheet.

Abstract: Speed bumps for mounting across roadway lanes to encourage vehicle drivers to slow down are formed of laminated layers of elongated flexible rubber strips secured together to form a speed bump unit. For low cost materials affording long life in service resilient long wearing steel belted tire tread strips are cut from the treads of discarded vehicle tires. Typical bump heights of three inches are obtained from six laminated half-inch thick layers. Layers lying flatly upon a road surface may be pyramided by a plurality of upwardly stepped layers of decreasing widths from the roadway surface to present inclined leading and trailing edges of the speed bump assemblies disposed to terminate in an uppermost crown. Fluorescent facings disposed on the speed bump unit surfaces give a driver visual night-time warning before the speed bumps are encountered by an approaching vehicle.

Abstract: Flat strips cut from discarded tires are stacked and stored as bulk rubber on pallets for easy handling, transport by fork lift trucks and storage in outside compacted storage space without accumulating water where mosquitos can breed. Typically flat rectangular longitudinal tread strips are folded and stacked in a plurality of abutting stacks about five feet high for rubber-to-rubber engagement in configurations extending substantially to opposite edges of a pallet platform, thus storing about a ton of bulk rubber per pallet. The pallets then may be transported and stored in compact stacks at outside locations without accumulating water and breeding mosquitos.

Abstract: A flexible impact energy absorption resilient and flexible rubber strip accessory has an adhesive layer for affixing it to an exterior curved automobile body surface. An inexpensive preferred embodiment is formed using tire tread strips cut from the carcasses of discarded automobile tires. Thus, steel belted tires provide embedded reinforcement for absorbing higher levels of impact energy without any visible damage to the tread strip or the adjacent car body surface upon which it is affixed. This accessory has an adhesive layer for attachment to a car surface having a manually protective paper or plastic cover so that it may be retrofit upon an exterior surface of an automobile without requiring any special tools. The accessory is universally adaptable to a large range of automobile body styles.

Abstract: This invention provides patterned tread strips of uniform shape and dimension from salvaged tire carcass tread strips adapted for producing products requiring stacked layers of tread strips. Novel methods of and apparatus for shaping the tread strips in one embodiment results in trimming edges of substantially rectangular shaped tread strips salvaged from tire carcasses having two shorter ends and two longer sides to produce precisely uniform width between the longer sides. Thus the longitudinal tread strips may be passed from one end longitudinally through a power actuated strip feeder which establishes slicing means operable at designated spacings near opposite edges of the tread strips to cut away edges and produce uniform longitudinal strip widths between said two shorter ends as the strips pass through the strip feeder. Other shaping embodiments of the invention include tread surface shavers for producing strips of precise thickness, and length cutters to provide specified lengths.
