ABSTRACT:
A concrete finishing adapter is disclosed which enables a user to adjust the angle of a bull float or the like, which is adapted for connection to the adapter. The angle of the bull float is adjusted so that it does not gouge into the unset surface of concrete. The adapter includes a base plate, a yoke, a handle receiving member extending through the yoke, a braking sleeve inside the yoke through which the handle receiving member passes, and a rod which connects the handle receiving member to the base plate. Rotation of the handle receiving member in either a clockwise or counter-clockwise direction causes the rod to move the base plate relative to the handle so that the angle of incidence of the base plate (and attached smoothing plate) relative to the concrete surface, is adjusted so that, when the user pushes the smoothing plate away, the forward edge of the smoothing plate is tilted upward. When the user reverses direction of movement and pulls the smoothing plate towards himself, he then rotates the handle so that the rear edge of the smoothing plate is tilted upward.
