Not illustrated. 1901 edition. Excerpt: The platfoim, which is wholly made of hard wood, exactly similar to an ordina1 y Liverpool lorry, has 95 sq. ft. of available surface for carrying goods. It is supported on springs and has no machinery fastened to it, so that it c an spring, bend, or crosswind under load without affecting the mechanism. The height of the platform is 4 ft. when light, and 3 ft. 9 in. when loaded with 5 tons. The wheels and steering are similar to vehicle No. C 2, The arrangement of the boiler and machinery is on the Musker automatic system; that is the supply of air and water to the boiler is designed to be wholly automatic, independent of the driver and in proportion to the amount of steam required, thus leaving the driver only to start, stop, or steer the vehicle. The boiler (Fig. 30) is the Musker semi-flash type, requiring no water level or water gauge glass, wholly made of weldless steel coiled tubing, with only three joints. It is fixed in front of the vehicle. The heating surface is 70 sq. ft., the grate area 2.5 sq. ft., and the test pressure stated to be 2,500 lbs. per square inch. The fuel used is steam coal or coke. The working pressure is 250 lbs. per square inch, and two safety valves, escaping into the chimney, are fitted. The feed pump is driven from the engine shaft by spur gearing, and the amount of water delivered to the boiler is automatically determined by a superheat regulator, the driver not having to give it any attention. The firing is central and from a hopper on the top of the boiler, the fierceness of ihe fire being automatically regulated by a steam pressure governor acting upon a centrifugal fan, and so shutting off or putting on the forced air blast, as more or less steam is required. No attention is required by the driver more
