Both Braithewaite& Miller and Sharp & Roberts used bal-anced drivers in about 1837, the two firmsseeming to work simultaneously. In 1841 J. G. Bodmer patented a devicefor using two pistons to balance eachother, similar to Shaws scheme, alsoStrongs perfect engine of to-day. In 1847 Heaton patented a device for areciprocating weight, driven by reversecrank on the axle. This was to offset theother reciprocating parts, and was similarin design to Ericsons scheme some yearslater. It was in 1845 when the balancing ofboth revolving and reciprocating parts bycounter-weights in wheel began to be. ports are 18 inches long, the admissionports iJ4 and the exhaust port 3 incheswide. Jerome gland packing is used. Caststeel wheel centers are used for the driv-ing wheels, and the engme truck wheelshave Krupp cast-steel tires. The boiler :smade of carbon steel, and is 62 inchesdiameter at smallest ring. Among the at-tachments specified are two monitor in-jectors, two encased consolidated safetyvalves, Westinghouse-American combinedbrakes on all drivers and tender, Sweenavbrake attachment, Le Chatelier waterbrake and California couplers.
