Glass cutting apparatus

A system for scoring a piece of glass along a specified line so that the glass may subsequently be broken along said line to impart a selected contour to the glass, said system comprising:

• a. a base with an exposed, horizontal surface;
• b. stop means for positioning the piece of glass to be scored on said surface of said platform;
• c. a glass cutter guide;
• d. said base including a component providing a set of adjoining, upwardly opening, square-sectioned cells of like dimension;
• and
• e. said glass positioning stop means including a main body member with means for engaging the piece of glass being scored and an elongated, longitudinally extending slot, a lug which can be installed in any one of the cells in said base component, and a threaded fastener which extends through said slot and into an internally threaded aperture in said lug, whereby said main body member can be rotated and rectilinearly displaced relative to said base to juxtapose said glass engaging means with the glass being scored and said fastener can thereafter be tightened to clamp said main body member against said base component with said piece of glass in a fixed orientation relative thereto and at a selected location therealong.

A system for scoring a piece of glass along a specified line so that the glass may subsequently be broken along said line to impart a selected contour to the glass, said system comprising:

• a. a base with an exposed, horizontal surface;
• b. stop means for positioning the piece of glass to be scored on said surface of said platform;
• c. a pivotable guide which is rotatable about a pivot axis at one edge of said base;
• d. a support means slidable along and lockable in fixed relationship to said pivotable guide;
• e. an elongated arm fixed at one end thereof to said support means for rotation about a second pivot axis extending normal to said base;
• and
• f. a glass cutter holder slidable along and lockable to said arm;
• g. whereby:
• (1) by sliding said support means along said guide and rotating said guide about the first-mentioned pivot axis, said second pivot axis can be positioned at a specified location on said base, and (2) by displacing said glass cutter holder to an appropriate location along said elongated arm and there locking it to said arm, an arc of selected dimension and with said second axis as its center can be scored on a piece of glass supported on said base.

A system for scoring a piece of glass along a specified line so that the glass may subsequently be broken along said line to impart a selected contour to the glass, said system comprising:

• a. a base with an exposed, horizontal surface;
• b. stop means for positioning the piece of glass to be scored on said surface of said base;
• and
• c. means for guiding a glass cutter along said piece of glass at a selectable distance from and parallel to said one edge of said base so that said glass can be scored along a line parallel to said one edge of said base and a strip of uniform width with parallel edges subsequently broken from said piece of glass, said guide means including an elongated straight edge extending from edge-to-edge of said base and having means at the opposite ends thereof for affixing the straight edge to opposite edges of said base in an orientation parallel to and at a selected distance from said one edge of said base.

A system for scoring a piece of glass along a specified line so that the glass may subsequently be broken along said line to impart a selected contour to said glass, said system comprising:

• a. a base with an exposed, horizontal surface;
• and
• b. means for positioning said glass on said base at a selected distance from said one edge thereof which includes:
• an elongated alignment guide with means toward the opposite ends thereof for locating said guide on said base parallel to said one edge of said base, at the selected distance from that edge, and in a specified location between the ends of the base;
• c. there being a set of adjoining, similarly dimensioned apertures opening upwardly onto the surface of the base;
• d. there also being an elongated slot in said guide at each end thereof which is oriented normally to said one edge of said base;
• and
• e. the means for securing said guide to said base including, at end of the guide;
• a lug dimensioned to snugly fit within a selected one of the upwardly opening apertures in said base and fastener means extending through the slot in that end of said guide and threaded into said lug and thereby tightenable to clamp said end of said alignment guide against said base after said ends have been adjusted relative to said fasteners to precisely position said alignment guide relative to said base.
