ABSTRACT:
Apparatus for scoring glass sheets comprises a rotary drive roll having a tire of resilient material for drivingly engaging the underside of a sheet of glass to be cut. A scoring wheel is mounted above the drive roll and is adjustable to move toward and away from a glass sheet for scoring the upper surface of the glass as the sheet is driven underneath by the drive roll. An adjusting element is provided for supporting and adjusting the position of the scoring wheel relative to the drive roll to maintain a selected scoring depth or as selected for the particular thickness of the glass sheet. Sheets of glass are manually guided and directed between the drive roll and the scoring wheel so that a nonlinear or curved score may be made on the glass surface. In addition, an adjustable guide is provided so that a linear score may be made at a selected distance from one edge of the glass sheet. The rotary drive roll is activated and controlled by a foot pedal which controls an electric motor that is mechanically connected to drive the roll.
