ABSTRACT:
A worker ballasted, propelled and guided wheel-like tool for imprinting predetermined surface patterns upon a slab of freshly cast, smoothed, yet still plastic concrete is disclosed. The wheel includes a generally cylindrical frame which is large enough to accommodate a worker in a walking position therewithin. The frame supports a plurality of rigid blades carried about the outside thereof, the blades being configured to provide the patterns desired. A walkway is provided on the inside of the frame for the worker and the frame may also be gripped by the worker as a handle, if desired. The weight of the worker is combined with the weight of the wheel to aid in driving the blades into the surface of the slab to a predetermined depth. The walkway enables the worker, by a walking movement in a forward direction, to propel the wheel over a path of the slab directed by the worker thereby forming the predetermined surface pattern therein. A plurality of tools of the same diameter may be peripherally linked together to increase simultaneous pattern imprinting width so that the combination of peripherally linked tools will span the width of larger slabs being poured.
