f/ycHT) SEPTEMBER 30, 1911. lohn Wilmer sends us greeting from Plattsburg, N.Y., in the above photograph, as '"From the man who fell from the balloon last October 2nd, 1 fly at Ottawa County State Fair, week September 11th." Anltalian^Passenger Record, AT the Mirafiori Aerodrome at Turin on the 21st, Rossi beat the Italian passenger record by covering 162 kiloms. in 2h. 2m. 29s. An Italian Aerial Post. ON the 20th inst. the Italian flyer, Dal Mistro, carried a bag of mails on his Deperdussin monoplane from Bologna to Venice, the 163 kilometres which separate these two points being covered in I hr. 28 mins. The New York Meeting. GRAHAME-WHITE and Sopwith attracted great crowds to the Nassau Boulevard Aerodrome on Sunday last, for the opening of the New York meeting. The former won the cross-country race, with Sopwith second, and the latter was also second in the passenger- carrying competition, while together they won the ten-mile relay race. Miss Maiilda Moisart secured the ladies' height contest, getting up to 1,200 ft. Two More American Fatalities. YET another fatal accident has occurred in America through an aviator being goaded by the jeers of the crowd into flying against his own judgment. At Troy, Ohio, Mr. Frank Miller experienced trouble with the engine of his machine and decided not to fly, but on this decision being communicated to the waiting crowd, they began to demonstrate their anger, and in order to appease them the aviator decided to make a trial. He was flying at a good height when, to the horror of the officials, flames were seen to break out round the motor. The machine fell to the ground, and on the officials reaching the wreck the aviator was found burnt to death. The second accident occurred at Mansfield, Pa., where, while flying at a height of 4,000 ft., a machine piloted by Caste'lane suddenly capsized and fell to the ground, the aviator being killed in the smash. The New Transatlantic Dirigible. THE new dirigible with which Mr. Vaniman intends to again try and cross the Atlantic has now been finished and taken to Atlantic City, where active preparations are being made in view of the proposed start on October 22nd. The airship has been named "Akron." ® ® ® ® THE NOBEL ENGINE. THE petrol engine illustrated and described herewith embodies special features on which the inventor invites criticism prior to putting the actual construction in hand. .-vjj One common or main poppet-valve, as shown, is provided in the cylinder-head. This valve acts both as an ingress for the charge and an egress for the exhaust gases. Upon the induction-stroke of the piston the fulcrum-lever, A, opens simultaneously both the in duction-valve, B, and the common valve, while at the same time a piston-valve, C, being in one with the induction-valve, travels downward, and thus closes the exhaust apertures situated around the cylinder-head, as shown. Upon the exhausting stroke the fulcrum-lever, D, opens the common valve only, the induction-valve bcii.g meanwhile on its seat, in consequence of which the exhaust apertures are open. It will be seen that by arranging the valve-levers to "clutch,'' as shown by plan of levers, no alteration to the cam motion is necessary, the standard practice of 2-to-i gearing being retained. The valve-box, E, is made a grinding tit in the cylinder-head, and can be readily drawn out en bloc wi' h the valves. The opening of the induction-valve being slightly in advance of the com plete closing of the exhaust ports, any remaining gases in the valve-box are forced out by the incoming charge. The desien of the cylinder having no valve-box abutments below the cylinder- head, readily allows of a circular copper water-jacket. The design simplifies the induction- and exhaust-pipes. It will be seen that the piston-valve, C, acts as a very substantial guide to the common valve, thus minimising the chances of the latter tilting on its seat.
