Abstract
A glass cutter for fracturing prescored sheet glass includes a C-shaped frame having in one end a glass supporting anvil and at its opposite end a screw operated breaker point. The glass sheet is positioned on the anvil with its scored line centered over a V-grooved channel in the anvil surface. A breaker screw is rotatably threaded in the opposite end of the frame and the screw which is perpendicular to the glass surface is provided with a breaker point that is brought into contact with the glass surface and then very slightly rotated to fracture the prescored glass along a very short length of the score line. By repeating these short fracturing steps, very intricate shapes may be cut in the glass without accidental breakage thereof.
Claims4
A glass cutter for fracturing prescored glass, said cutter comprising:
- a frame having an elongated base section and an elongated upper section having a first end attached to the first end of said base section and extending over said base section and separated therefrom, said base section and said upper frame section forming a "C" shape;
- an anvil positioned adjacent the second end of said elongated base and on the surface thereof facing said upper frame section, said anvil having a flat glass supporting surface and a channel of substantially uniform width and depth along the length of the center line of said glass supporting surface;
- and
- a threaded breaker screw having a breaker point on one end of its longitudinal axis, said screw being rotatably positioned in the second end of said elongated upper section, said longitudinal axis being perpendicular to said glass supporting surface of said anvil, said breaker point being substantially aligned with the center line of said channel in said anvil.
