  • Paving machine with enclosed material compartment
    Patent number: 4012160
    Abstract: Two feed conveyors and two spreader augers are independently driven, each by its own drive motor. The control means for each feed conveyor includes a sensor at the discharge end of the feed conveyor and means responsive to changes in the level of the paving material at the sensor for proportionally increasing the drive speed of the conveyor as the level drops and proportionally decreasing the drive speed of the conveyor as the level rises. The control means for each auger includes a sensor adjacent the discharge end of the auger and means responsive to changes in the level of the paving material at the sensor for proportionally increasing the drive speed of the auger as the level drops and proportionally decreasing the drive speed of the auger as the level rises. The paving material compartment, which includes the feed conveyors and spreader augers, is enclosed. Fumes are pumped out from the enclosed feed path and into a pollution control device.
