[35] Telling of the first use of the car in later days, Frank Duryea mentions the many noises and vibrations that accompanied the trip: the vibrating tiller, the tinny sounding muffler, the clattering chains. He later reported speeds of 3 mph in low gear and 8 mph in high gear. [36] Letter from Frank Duryea to Charles Duryea, Jan. 19, 1894, says they went up hill via Summer and Armor Streets, then out Walnut to Bemis' at Central Street School. [37] The letter read: "I have designed a new muffler and we will proceed to make it before long, in a day or two. Instead of one shell 1/8-inch thick I shall put a shell 1/16-inch thick inside another of equal thickness, but about 1 inch greater diameter i.e., one chamber within another so as to cause sound to turn corners to get out. Still another shell will be added if it prove insufficient, making it turn about again--taking care in each case to give ample room for expansion--outer one need not be more than 1/32 inch possibly. Will let two threaded rods with nuts hold heads on both or on three cases, if the 3d be essential." [38] This letter gives further proof that the car never had a brake. Frank said the car came back down the hill with no brake, but that the engine held the vehicle back. [39] DURYEA, op. cit. (footnote 5), p. 37. [40] It is possible that a few parts were removed at this time to be used on the two-cylinder car. The muffler may have been one of these, and even more likely, the governor parts. Charles Duryea wrote to C. W. Mitman December 27, 1921, stating that his younger brother Otho and a Henry Wells had put in a battery and gasoline in 1897 and started the engine. Because the chains were not on the car they could not attempt to operate it; but the engine ran too fast, and finally something broke, probably the engine frame, found to be broken during the recent restoration. Charles thought the engine ran too fast because some of the governor parts were already missing. [41] Recorded interview with Frank Duryea in the U.S. National Museum, November 9, 1956. On the formation of the Duryea Motor Wagon Company, Mr. Markham was rewarded for his part of the venture. He had invested nearly $3000 in the work, and sold out his rights in the company for approximately a $2000 profit. * * * * * Paper 34 - Transcriber's Note The transcriptions retain all typographical and gramatical errors. * * * * * CONTRIBUTIONS FROM THE MUSEUM OF HISTORY AND TECHNOLOGY: PAPER 35 THE BORGHESI ASTRONOMICAL CLOCK IN THE MUSEUM OF HISTORY AND TECHNOLOGY by _Silvio A.
