A MACHINE THAT FINISHES FOUR PISTONS ON THE TOP AND SIDE WALLSSIMULTANEOUSLY George Baldwin Selden, of Selden patent fame, probably lost untold millions by a simple little diaryentry. His patent was applied for nearly two decades before the building of the first successful American automobile, but was not issued until years after. When hesaw what isnow the accepted type of four-cycle motor, he wrote, "Another of those d- d Dutch engines." On that entry the courtsheld hewas not thinking of such an engine when he patented his vehicle, arid therefore that the building of the modern motor car did not infringe his patent, although itwas valid for other types of engines.
