<p>A tile scoring and fracturing device in which spaced parallel links swingably secured at one end to a base and freely secured at their other ends to the ends of an elongated guide bar to form a rectangular assembly can be shifted to a parallelogram configuration to lower the guide bar toward a tile placed upon the base. A combined tile scoring and fracturing head is slidably carried upon the guide bar. In the rectangular mode the scoring and fracturing head is used to score the tile along a predetermined path. Thereafter, as the links and guide bar are shifted to the parallelogram configuration the tile is fractured by the said head.</p> |
