ABSTRACT:
Glass cutter (or scoring) apparatus for hand usage adapted to facilitate a preferred cutting procedure wherein the glass to be cut is itself moved with respect to a stationary cutter or stylus to provide a desired score line. A glass cutter that may have a cutter wheel or stylus is supported above a glass receiving table by a cutter support arm that extends forwardly from a fulcrum support. A force that may be adjusted is applied to the arm to hold the cutter engaged with the glass, and the glass is then moved in a hand guided or mechanically guided pattern to score the glass. Guide fence and pivot elements are provided for non-freehand specialty uses. The cutter may be moved to adjusted positions of varied distance and angularity to facilitate operations, and in one preferred embodiment the cutter support arm itself may be moved reciprocally to facilitate conventional glass cutting procedures wherein the cutter is moved with respect to the glass being cut. In connection with the preferred cutting procedures, both of the user's hands may be used to guide the glass being cut, and, accordingly, glass pieces of intricate and accurate shapes of the type being used in stained and art glass work may be efficiently cut. To facilitate usage of the device in connection with stained or art glass projects, patterns are provided on adhesive backed paper or film with segments of the pattern or of an obverse presentation thereof being applied to the glass that is to be cut whereby the placement of score lines is accurately controllable.
