[1]Dated on the assumption that it was written after Rudolf Goldschmidt had requested the opinion in Abs. 25. [2]US Patent 1386329, “Mechanism for Converting Rotary into Reciprocatory Motion.” Rudolf Goldschmidt, assignor to Det Tekniske Forsøgsaktieselskab, Charlottenlund, Denmark. Filed on 10 January 1921. [3]The first claim of the patent is given as follows: “Mechanism for converting rotary into recipro- catory motion wherein continued progressive movement step-by-step in one direction of the path of reciprocation is obtained, comprising a reciprocatory member, a centrifugal weight pivoted thereto, means for rotating said weight and means for impressing a unidirectional impulse upon the recipro- catory member, so that it travels or progresses step-by-step in one direction.” [4]Einstein’s quote is from a German draft of the patent, [35 495].
