US Patent 1386329, “Mechanism for Converting Rotary into Reciprocatory Motion.” Rudolf
Goldschmidt, assignor to Det Tekniske Forsøgsaktieselskab, Charlottenlund, Denmark. Filed on
10 January 1921.
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.”
Einstein’s quote is from a German draft of the patent, [35 495].
