The eccentric is provided with acurved rack near its periphery which meshes with a small pinion. The pinion is secured to the end of ashaft provided with a groove dis-posed spirally for a portion of itslength. The shaft is journaled intwo collars or flanges keyed tothe main shaft so that the smallshaft lies parallel to the engineshaft. A third collar slidablymounted on the engine shaft isprevented from turning by asuitable key, this collar carrying the strap to which the reversing leveris connected. A pin in the latter collar engages the groove in thesmaller shaft and when this collar is shifted sidewise the pin causes thesmaller shaft to revolve, which turns the eccentric around on the engineshaft and thus shifts the position of the valve. 210. Longitudinal section, showing the spiral grooved shaft and pinion. 211. ENGINE STOPPING MECHANISM. If the governorbelt breaks, the weight N will drop, and through the system of levers and links throw the bell-crank lever B
