Abstract: A cutter drum for pavement profiler machines has readily replaceable hardened tooth holders bolted to mounting bases. The teeth and holders function over extended periods of time without excessive wear. The tooth holder mounting bases, which have overlapping portions through which a bolt extends to hold the tooth holder in position, are formed of softer steel readily weldable to the cutter drum surface. Complementary surfaces on each of the tooth holders and an adjacent mounting base resist forces acting on the teeth during cutting operations.

Abstract: A cold surface pavement planer, used to scarify and profile concrete and asphaltic pavements, is constructed with a sealed cutter drum. A gear box in the cutter drum, transmitting power to the cutter drum from an engine on the planer chassis, is cooled efficiently by a coolant liquid in the cutter drum in which the gear box is partially immersed.

Abstract: A road roller comprises a frame and a pair of drums, at least one of which is a guide drum, on which the frame is pivotally supported. A steering mechanism is attached to the guide drum for steering the road roller. The supporting mechanism for the guide drum includes a vertical pivot shaft coupled to the guide drum, a vertical anti-friction bearing on the pivot shaft for permitting the guide drum to pivot horizontally relative to the frame, and a flexible support coupled between the bearing and the frame for permitting limited lateral twisting of the guide drum relative to the frame. The flexible support comprises a pair of longitudinally spaced rubber mounts for absorbing longitudinal shocks but for inhibiting longitudinal twisting of the drum relative to the frame.
