Patent ID: 7156577

Claim:
A vibratory concrete finishing tool comprising: an elongated handle formed with a cylindrical configuration having an uppermost end and lowermost end; a concrete working device having a planar bottom surface adapted to engage a wet concrete surface, and a receiver for removably receiving the lowermost end of the handle; a clamping and vibration transmitting arrangement coupled externally to the lowermost end of the handle in spaced relationship from the working device; and a vibratory mechanism fixed to the clamping and vibration transmitting arrangement so that the vibratory mechanism is held in spaced relationship with the handle, the vibratory mechanism having a spinning crankshaft assembly with an eccentric weight mounted thereon, and an engine mounted in a housing for driving the spinning crankshaft assembly, wherein the clamping and vibration transmitting arrangement and the vibration mechanism are both spaced from and completely independent of the working device so that vibration is transmitted directly and exclusively through the handle to the working device.
