ABSTRACT:
The apparatus has a housing which slidably mounts a blade assembly for reciprocation thereof, fore and aft, perpendicular to the longitudinal axis of the housing, for the purpose of cutting shingle nails. The blade assembly slides upon a plate, which terminates in a series of juxtapositioned teeth, which lifts shingles to give the blade assembly access to the nails. A prime mover, an electric motor in the disclosed embodiment, drives the blade assembly in reciprocation through a gear train and cranks confined within the housing. Vibration-induced, free-flow lubrication for the blade assembly is provided by a lubricant reservoir and manifold mounted upon the housing.
