ABSTRACT:
A long-handled float device for leveling wet concrete includes mechanism attaching a handle to a float which is adapted to allow a user to adjust the relative angle between the float and the handle. The adapter connecting the shaft to the float includes a yoke, a yoke shaft coupler, a sleeve through which a sleeve guide shaft passes, and a link arm which connects the sleeve to the yoke. Rotation of the handle about its own axis causes sleeve guide shaft rotation which causes movement of the sleeve along the guide shaft axis which is transmitted to the yoke via a link arm causing the angular relationship between the float and the handle to change. By such adjustment, the user may tilt the front float edge upward when the assembly is pushed away from the user. Upon reversing direction, the user may tilt the back float edge upward.
