Abstract
A portable vibrating roller includes an outer roller structure having a plurality of grooves and ribs. A hollow cylindrical bore extends longitudinally through the shell. A vibration system having a first end cap and a second end cap fits within the bore. A battery positioned within the shell near one end cap provides electrical power to a motor positioned within the shell near the other end cap to cause the motor to rotate an output shaft at a plurality of angular velocities to rotate an eccentric mass located approximately midway between the two end caps. The rotating eccentric mass causes vibration. A motor control circuit receives input power from a battery and selectively provides output power to the motor in response to the operation of a switch on the first end cap. The output power is varied to control the angular velocity of the output shaft of the motor and to thereby control a frequency of vibration caused by the eccentric mass.
