  • Patent number: 6296467
    Abstract: A vibrating screed for surfacing concrete comprises a surfacing blade, a pair of handle assemblies mounted to said blade, a motor, vibration causing mechanism and a transmission connecting the motor to the vibration causing mechanism such that, when the motor is in operation it causes the transmission to rotate with the transmission being adapted to impart a vibratory motion to the blade. The transmission includes a flexible joint having an angled configuration to allow the motor to be mounted rearwardly of a leading edge of the blade. Each handle assembly comprises a main elongated tubular member and a handle mounted at a proximal end thereof. The handle includes a first tubular element mounted around the main tubular member, a second tubular element extending sideways from the first element and a third tubular element extending around the second element, with a grip member being mounted to the third element.
