Disclosed is an improved apparatus for scoring glass wherein a scoring wheel is rotatably mounted on an axle within a novel mounting bracket. The mounting bracket can be the extension of the handle of a manual glass scoring device or integrated within a cartridge for an automated or semi-automated glass scoring machine. One of the unique features of the improved apparatus of this invention resides in the spatial geometry of the clearance between the mounting bracket and the scoring wheel. The enhanced degree of clearance between these two components substantially reduces maintenance requirements and improves consistency of performance. This results in reduction in accumulation of glass chips between the wheel and the mounting bracket, thereby insuring continuous freedom of movement of the scoring wheel within the bracket even after extended periods of use. Such enhanced clearance also enables simple and precise lubrication of the axle which supports the scoring wheel. Another of the unique features of this invention resides in the design and construction of the adjustable spindle to which the mounting bracket is attached. This spindle is internally spring loaded thereby providing an enhanced degree of precision bearing surface between the spindle and the guide channels within the arbor of a glass scoring machine.
