Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A device for tamping and leveling concrete and the like which comprises: an elongated member having a substantially flat bottom surface, said member defining a downwardly-open aperture adjacent an end of said member; a housing mounted to said member above said member; a shaft extending parallel to the bottom surface of said member, said shaft being rotatably mounted within said housing; several weights eccentrically mounted upon said shaft at spaced apart locations within said housing; drive means for rotating said shaft and said weights mounted thereupon, said drive means including a motor connected to and operable to rotate said shaft, the motor being mounted to and supported by said member and positioned adjacent an end of said member; and handle means for permitting control of the movement of said member along a surface, said handle means including a stake received within and extending downwardly through the aperture defined by said member.
Claim 2
Independent Claim
151 words
A device for tamping and leveling concrete and the like which comprises: an elongated member having a substantially flat bottom surface, said member defining a downwardly-open aperture adjacent an end of said member; a housing mounted to said member above said member; a shaft extending parallel to the bottom surface of said member, said shaft being rotatably mounted within said housing; several weights eccentrically mounted upon said shaft at spaced apart locations within said housing; drive means for rotating said shaft and said weights mounted thereupon, said drive means including a motor connected to and operable to rotate said shaft, the motor being mounted to and supported by said member and positioned adjacent an end of said member; and handle means for permitting control of the movement of said member along a surface, said handle means including a stake received within and extending downwardly through the aperture defined by said member.
Claim 3
Dependent Claim
36 words
The device of claim 1 in which said enclosure is rectangular and includes parallel, spaced apart vertical sides extending upwardly from the bottom surface and further includes a top extending between and perpendicular to the sides.
Claim 4
Dependent Claim
43 words
The device of claim 1 in which the bottom surface of said enclosure is rectangular and has a longitudinal axis, said shaft extending in a plane which is perpendicular to and extends through the longitudinal axis of the bottom surface of said enclosure.
Claim 5
Dependent Claim
63 words
The device of claim 1 in which said handle means includes a handle connected to and extending outwardly from a first end of said enclosure, the motor of said drive means being mounted upon the handle of said handle means at a location spaced outwardly from said first end, the aperture of said member being located adjacent the second end of said member.
Claim 6
Dependent Claim
35 words
The device of claim 1 in which the motor of said drive means includes a drive shaft operable to be rotated by the motor, the drive shaft being coaxial with and connected to said shaft.
