  • Pressure roller stand for forcible longitudinal displacement of large rotating drums
    Patent number: 3966395
    Abstract: A stand is provided to carry a pressure roller in horizontal engagement with a longitudinal surface of a raceway about a large rotating kiln or other drum, the roller being displaceable in a longitudinal direction to force the raceway to oscillate across its radial support rollers, thereby to increase the life of the raceway under wear from concentrated mechanical support stresses. An hydraulic cylinder selectively displaces the roller by acting on a frame on or in which the pressure roller is carried.
