Abstract
A motor driven power hand tool and adapter reciprocating a modified hand file in pressured engagement with a work piece by manipulating a lever resistance intermediate the opposite ends of a file which becomes a second class lever operating with a fulcrum at its reciprocally driven end and with work force applied at its other end, the invention residing in the adapter that guides the file as an aftermarket device and in combination with the power hand tool.
Claims15
A motor driven workpiece cutting tool with a power head reciprocating a ram-rod on a forwardly projecting axis, and including;
- an elongated file having a flat base portion with top and bottom faces and coupled to the ram-rod to be reciprocated thereby, and having an extended portion and bottom face thereof with cutting means on said bottom face,
- and a file adapter extending forwardly from a power head of the tool and positioning a resistance means for engaging and downwardly pressing the top face of the base portion of the file forwardly of its coupled engagement to the ram-rod and rearwardly of said extended portion thereof,
- the file being a second class lever with its fulcrum coupled to the ram-rod, its resistance downwardly pressured at the flat base portion of the file, and with working extended portion with said cutting means for forcibly engaging a workpiece.
A file for coupled engagement to a ram-rod of a workpiece cutting tool with a power head reciprocating said ram-rod on a forwardly projecting axis, the file including;
- an elongate body with top and bottom faces with cutting means on at least one of said faces and having a vertically disposed mounting plate extending from a flat base of the file and perpendicular to the top and bottom faces thereof, and a fastening means opening through the mounting plate for receiving a coupling fastener to the ram-rod.
A file adapter for a motor driven workpiece cutting tool with a power head reciprocating an elongate file coupled to a ram-rod reciprocated thereby on a forwardly projecting axis, the file having a flat base portion with top and bottom faces, having an extended portion and bottom face thereof with cutting means on said bottom face, and including;
- a forwardly extending member carried by the power head of the tool and positioning a resistance means for engaging and downwardly pressuring the top face of the base portion of the file forwardly of its coupled engagement to the ram-rod and rearwardly of said extended portion thereof,
- the file being a second class lever with its fulcrum coupled to the ram-rod and its resistance downwardly pressured at the flat base portion of the file, and with a working extended portion cutting means for forcibly engaging a workpiece.
