Abstract: 14,090. Winton, A. May 25, [date applied for under Patents Act, A.D. 1901]. Motor road vehicles.-Relates to road vehicles driven by explosive engines. The framing of the undercarriage is made up of the cylinder and crank casings, and a water-cooler, bolted to two longitudinal sills, so that cross-sills are unnecessary. The explosion ends of the cylinders are so disposed that the gas-inlet valves, which are in a detachable casing, and also the sparking-plugs, are readily accessible. The inlet valves to the cylinder and the gasoline-inlet valve to the carhuretter are controlled by fluid pressure, preferably air supplied by a pump worked from one of the engine pistons, for the purpose of regulating the speed and power. Fig. 1 shows a plan of the vehicle with the body removed, Fig. 3 shows a sectional view on the line 3-3 of Fig. 1 and Fig. 4 shows a view of one of the detachable' inlet valves. The framing of the engines 1, 2 is bolted to the longitudinal sills 5, 6 so that the inlet-valve casings 18 are below the sill 5, and on one side of the vehicle. The water-cooler is also bolted to the sills, so as to brace the undercarriage further. The explosive mixture is led from the carburetter 25, shown in Fig. 6, to the casings 18 by a pipe 19. A pump 42 worked from one of the main pistons 44 supplies air under pressure to the inletvalve casing through the pipe 45 and the opening 40 to the cylinders 35. The inlet valve 20, which is opened by the suction of the main piston 47, is kept closed by the air pressure on the piston 34 and the spring 39. The amount of opening of the valve is thus regulated by the pressure of the air supplied. By the application of a somewhat similar arrangement to the gasoline-inlet valve 55 of the carburetter, the proper composition of the explosive mixture is maintained for all variations of power. A relief valve 48, of the kind described in Specification No. 900, A.D. 1897, [Abridgment Class Air &c. engines], in the air-supply pipes allows the air pressure to be decreased, and therefore the speed of the engines to be increased, at will ; but for normal slow running of the engines, as at starting or standing, an adjustable escape valve is provided. The rotary circulating-pump 76 is driven from the exhaust-valve operating - gearing, and the cylinders of each engine have a common water jacket communicating with the water-cooler. The flywheel is constructed of a metal collar 88, connected to the shaft by a disc, and by arranging friction shoes on the inside of this collar the flywheel forms a clutch member. For reversing, the clutch 90 carries the gear 109 which meshes with the gear 114 carried on the pivoted arm 110, as shown in Fig. 7. The clutch being out of action, the rod 118 brings the wheels 114, 109 in gear, and a further movement brings the friction roller 117, to which is connected the pinion driving the wheel 114, in gear with the collar 88. To allow for the action of the springs supporting the frame on the back axle, a yielding connection 106 used in conjunction with a universal joint is provided, longitudinal movement also being allowed by means of the sliding sleeve connection 107. The yielding connection 106, shown in Figs. 10 and 11, comprises blocks of rubber 130, placed between the arms 129 of the piece 125 keyed to the shaft, and the arms 128 of the piece 126 loosely mounted on the shaft and connected to the universal joint 104.
