  • Patent number: 6112413
    Abstract: A shingle severing device includes a cutter pivotably secured to a work carrier. The work carrier mounts spaced blades and the cutter mounts spaced blades alignable with the work carrier blades. A shingle support and fences locate a conventional shingle. With an elongate roofing shingle placed on the support, the cutter and work carrier are moved from an open position to a closed position to sever the shingle along two spaced lines. A stop prevents overtravel beyond the closed position. The severing removes from the roofing shingle a ridge shingle with a trapezoid shaped end.
