ABSTRACT:
A multi-sided wheel to replace one of the wheels of an existing cold milling machine. The wheel has a series of flat surfaces in spaced relationship. The flat surfaces allow the machine to drop its cutting drum relative to the surface over which the machine is traveling to cut a rumble strip. As the wheel rotates, it will support the machine on one of the points formed by the confluence of two adjacent flat surfaces, thereby raising the machine and causing it to raise its cutting drum out of the rumble strip that it has just cut. Because the flat surfaces are spaced apart, the cutting drum will be moved forward in a looping fashion as the wheel rotates before the wheel drops onto the next flat surface to lower the cutting drum for cutting the next, spaced rumble strip. Thus, the multi-sided wheel causes the machine to move up and down as it propels along its path of travel. A pentagonal wheel is the optimal design for use in conjunction with a Wirtgen.RTM. W500.TM. cold milling machine in order to cut rumble strips meeting the specifications of the New York Thruway Authority.
