Abstract

A traction tool for scraping away excessive grout between the joints of adjacent tile pieces of a floor or wall. The tool is fitted with a handle fixed to a base with a plurality of toothed wheels rotatably fitted in the base to extend below the undersurface of the base, the plane of all wheels lying on a common plane perpendicular to the undersurface of the base. The tool could be used to remove old grout prior to making a freshly grouted joint.

Claims

1. A tool for removing grout from a joint between tiles laid upon a common surface, comprising

A base having a substantially planar underside fitted on a top side with a projecting handle, and fitted on the opposed underside with the projecting circumference of a single line of more than two wheels, with all of said wheels individually aligned along a common plane substantially perpendicular to the underside, and with each wheel rotatably mounted in a recess in the said base, with

each said wheel formed on its periphery with a continuous scalloped cutting edge to form concave recesses each separated by pointed teeth, each said wheel projecting approximately one-eighth of an inch beyond the underside so that they can roll in a common joint line between tiles.

2. The combination as recited in claim 1 in which three said wheels are mounted to the base.
