ABSTRACT:
An apparatus and methodology for smoothing relatively small pads of freshly laid concrete. The apparatus comprises a pair of broom assemblies joined by a gang bar structure and each pivotally movable on the gang bar structure between first and second angularly displaced positions. A first rope is connected to the apparatus and moves the apparatus across the pad in one direction in response to pulling on the first rope, and a second rope is connected to the apparatus and moves the apparatus across the pad in an opposite direction in response to pulling on the second rope. Utilizing the smoothing apparatus, and with first and second workers positioned on opposite sides of the pad and the broom assemblies in their first angular positions, the apparatus may be moved in one direction across a first section of the pad, with the first worker pulling on the first rope and the second worker commensurately letting out the second rope, whereafter the apparatus may be moved laterally on the pad to overlie a second section of the pad laterally adjacent the first pad section and the apparatus may be moved in the opposite direction across the second section of the pad with the broom assemblies in their second angular positions, the second worker pulling on the second rope, and the first worker commensurately letting out the first rope. This procedure is repeated for successive pad sections with the direction of movement of the apparatus being reversed for each successive section.
