The combination of a hand held mounting mechanism having an elongated tubular member containing a rotating shaft, where the elongated tubular member includes a cone-shaped bracket at a free end thereof, and a concrete slumping implement. Several embodiments are disclosed, where in each the implement comprises a concrete contacting plate, either flat and/or sectional, or contoured, an upstanding wall extending therefrom, and an L-shaped bracket for mounting to the cone-shaped bracket. Additionally, the rotating shaft may mount an eccentric wheel for imparting a vibrating or cyclic action to the concrete slumping implement.

1. In combination with a hand held mounting mechanism featuring an elongated tubular member within which is a shaft for rotating movement, means for rotating said shaft, and a remote end on said shaft receiving a cone-shaped bracket for fixedly mounting a concrete slumping implement and an opening through which a free end of said rotating shaft projects, a concrete slumping implement for slumping and screeding a cementatious material, said implement comprising: a concrete contacting plate with the capability to effect the simultaneous slumping and screeding of nonplanar areas of said cementatious material, said contacting plate having a first edge mounting a two-section generally perpendicular wall extending therefrom, an L-shaped bracket mounted on a first said section to said perpendicular wall and a second said section having means for fixedly mounting said cone-shaped bracket, where said second section further includes an opening for receiving said free end of said rotating shaft, and an eccentric wheel mounted to said free end of said rotating shaft, whereby rotation of said eccentric wheel imparts a vibrating action to said concrete contacting plate. 2. The combination according to claim 1, wherein said concrete contacting plate defines a plane, and said elongated tubular member is angled less than 90° to said plane. 3. The combination according to claim 2, wherein said concrete contacting plate is in two sections to allow for the angular movement of one section to the other. 4. The combination according to claim 3, wherein said two sections are hinged along a common edge. 5. The combination according to claim 2, wherein said concrete contacting plate is a curved piece for contouring a curb profile. 6. The combination according to claim 1, wherein said concrete contacting plate includes a lower face having a pin projection extending downwardly therefrom, where said pin projection may be used as a guide for moving said concrete slumping implement. 7. In combination with a hand held mounting mechanism featuring an elongated tubular member within which is a shaft for rotating movement, means for rotating said shaft, and a remote end on said shaft receiving a cone-shaped bracket for fixedly mounting a concrete slumping implement and an opening through which a free end of said rotating shaft projects, a concrete slumping implement for slumping and screeding a cementations material, said implement comprising: a concrete contacting plate having a first edge mounting a generally perpendicular wall extending therefrom, said perpendicular wall consisting of a pair of planarly aligned sections, an L-shaped bracket mounted on a first said section of said perpendicular wall and a second said section having means for fixedly mounting said cone-shaped bracket, said first wall section including a pair of arcuate slots for selectively fixing complementary fastening members to said first leg of said L-shaped bracket, said second section including an opening for receiving said free end of said rotating shaft, while said second section is fixed to said first leg of said L-shaped bracket, whereby rotation of said eccentric wheel imparts a vibrating action to said contacting plate.
