NOTCHING TOOL

摘要

EDGAR MALCOLM STUBBERSFIELD and LESLIE VICTOR SHAW A notching tool for forming notches in ridge- or hip-capping for roofs, the notches being formed to match the profile of the roofing sheets. The tool has a base with a pair of spaced feet i which engage the ribs on the roofing sheets to align the tool. A notching head on the base has a replaceable die and punch pair, one of which is fixed to support the capping while the other is manually or power-operated to provide a shearing-type cutting action between the die and punch to cut the notches. Adjustable guides on the notching head support the capping for angular alignment between the capping and the notching head and for adjustment of the depth of the notch. The notching head may be pivotally and/or rotatably mounted on the base and the die and punch may be reversible.
