Description:

According to a history in Porter-Cable Mach. Co. v. Black & Decker Mfg. Co., 274 F. Supp. 905 (1967), Porter-Cable decide to design a saber saw that would be competitive with the dominant product at the time, the Swiss-made Scintilla. They ended up with two different designs: one was from a team led by Walter Papworth, as seen in this patent. The other design, due to John P. Bruck and Frank W. Mittins, used an orbital action. That orbital action led to excess chipping of the upper surface of the cut material, and was rejected by Porter-Cable's sales department.
