The power is transmitted from the motorto the gear box through a leather-faced cone clutch fittedwith ball thrust withdrawing bearing. At the engine speedof 900 the gears provide three speeds—5 , and 15 —in either direction. The gears areof the sliding type, and are case-hardened. Power is transmitted from the gear box to the axlesby a bevel reducing gear, one on each axle. T

Power is transmitted from the gear box to the axlesby a bevel reducing gear, one on each axle. The gearingruns in thick oil or grease, and is inclosed in oil and dust-tight, cast-iron casings. The driving shafts from thegear box have universal joints to allow for the play of thesprings. The motor is fitted at the front of the frame, inclosedby a suitable sheet-steel casing. It is of the four-cylinder,vertical type, with cylinders 5 in. x 5% in., and developingupward of 32 The principal feature of the engine. View of Truck Showing Gasoline Engine and DrivingEquipment consists in the placing of the cam shaft which actuates theinlet and exhaust valves, as well as the ignition tappetson the top of the cylinders. By this means the inlet andexhaust valves are arranged at opposite sides of the cyl-inders, and actuated with one common shaft which isdriven off the crankshaft by means of skew bevel gear anda vertical shaft. The cam shaft and cams are one forging &73 of nickel steel. Motion is transmitted to the valves bymeans of the rocking levers at each side. This arrange-ment is used to insure great certainty of action with theleast wear. The case-hardened cam shaft and rollers atthe end of the rocking levers run in an oil bath. The easy access to the valve gear renders the enginehighly suitable for railway work. The entire valve gear
