Abstract

This bull float includes an elongate handle detachably connected to a concrete finishing float. The coupling between the handle and the float includes a plug and socket connection provided with a detent sleeve which holds related pin and slot parts in engagement. The coupling also provides a tilt control including a shaft connected to the end of the handle and relatively rotatable therewith. The shaft is axially rotatable about its own axis and is pivotally connected to the float. A pair of cables reversely wound on the shaft and secured to spaced points on the float changes the angle of tilt as the handle is rotated.

Claims

1. A concrete finishing float comprising:

a. handle means, b. float means including a finishing face, c. coupling means connecting the handle means to the float means and including;

1. shaft means attached to the handle means, 2. first pivot means attaching the shaft means to the float means for axial rotation of the shaft means, 3. second pivot means attaching the shaft means to the float means for inclination of the shaft means relative to the finishing face, and 4. means selectively controlling the angle of inclination between said finishing face and said shaft means including a pair of flexible elements attached between the shaft means and the float means in reversely wound relation.

2. A finishing float as defined in claim 1, in which:

d. the shaft means includes an elongate shaft having axially spaced stop means, e. the first pivot means includes a relatively rotatable sleeve means mounted to said shaft between said spaced stop means, and f. the second pivot means connects said sleeve means to said float means.

3. A finishing float as defined in claim 2, in which:

g. the second pivot means includes a pair of overlapping plates connected by a pin transversely disposed of the shaft, and h. one of said plates is fixedly attached to the sleeve means and the other of said plates is fixedly attached to said float means.

4. A finishing float as defined in claim 3, in which:

i. the flexible elements are disposed on either side of the pin.
