ABSTRACT:
A device is disclosed herein for simultaneously tamping and leveling concrete and similar materials. The device includes an elongated, rectangular enclosure having a substantially flat bottom for acting upon the concrete or other material. A shaft extends within and is rotatably mounted to the enclosure, and is connected at one end to a motor which is operable to drive the shaft in rotation. Several weights are eccentrically mounted upon the shaft at evenly spaced locations. Preferably several bearing houses are mounted within the enclosure and the shaft is rotatably received therein, each of the several weights being positioned adjacent one of the bearing houses. A handle extends outwardly from one end of the enclosure and the motor which drives the shaft is preferably mounted upon the handle at a location spaced outwardly of the enclosure. The other end of the enclosure may include a handle or may rest upon a stake received within a downwardly open aperture in the enclosure.
