A hammerless mechanical attachment system comprising a C-clamp member, a first wedge member, a second wedge member and a threaded tensioning device for attaching a tooth adapter to a base cutting edge of an implement. The C-clamp member has a generally C-shaped body with a forwardly facing abutment surface and a forwardly extending flange having a threaded aperture therein. The first wedge member has a forward side having a first wedge surface thereon, an opposite rearward side having a second abutment surface thereon positionable against the first abutment surface of the C-clamp member, and a through bolt hole disposed along a longitudinal axis parallel to the second abutment surface. The bolt hole is disposed in alignment with the threaded aperture in the flange when the second abutment surface is placed in abutment with the first abutment surface of the C-clamp. The second wedge member has a rearwardly facing side having a second wedge surface thereon and a forwardly facing side having a third abutment surface thereon. The second wedge surface is positionable in abutting relationship with the first wedge surface of the first wedge member. The threaded tensioning device is disposed through the bolt hole in the first wedge member and threadably engaged with the threaded aperture in the flange of the C-clamp member, whereby the second wedge member is caused to move in a forward direction upon tightening of the threaded tensioning device for securing the adapter to the base edge. |
