ABSTRACT:
A shingle cutting apparatus includes a base, a lever arm pivotally mounted to the base, and a pair of diverging cutting blades mounted to the lever arm. The base includes a shingle-receiving surface upon which a shingle may be positioned for cutting. A pair of grooves are defined in the shingle-receiving surface corresponding to the positions of the cutting blades. In operation, the lever arm is moved downwardly against a shingle, and the cutting blades extend through the shingle and into the corresponding grooves in the base. A ruled back stop and a removable end stop are included to facilitate desired cutting of a shingle. The apparatus may be modified to replace the pair of diverging blades with a single, perpendicular blade for cutting straight-line partial shingles. The apparatus is particularly useful for cutting partial shingles in a variety of widths, and most particularly for cutting the conventional six-sided ridge cap shingle.
