Abstract
A combination bull float, hand trowel, groover for use in conjunction therewith, and an elongated handle for attachment with the groover, or the bull float, is provided, with the groover being connectable with either of the bull float or the hand trowel for use in perfecting the finishing of freshly poured concrete. The bull float includes a plate portion having upstanding front and back walls extending upwardly therefrom, with the groover being only slightly longer than the width of the plate portion and incorporating connecting means for fastening it to the bull float, and for providing both a finishing and grooving of the concrete during its working. An elongated handle connects to a bracket upon the bull float, while the groover, if independently used, is also secured through a connector with the elongated handle for facilitating its independent usage for the grooving of finished concrete. The hand trowel is also designed to accommodate the groover, containing a plate member having upturned flanges that cooperate with engaging components of the groover to provide for its removable but secure fixing to the trowel during its usage in both finishing concrete, and providing the necessary expansion groove therein.
