1230 THE COLLIERY GUARDIAN. June 6, 1913. engine, the area of the outlet orifice or orifices from the governor cylinder being made so that the engine throttle valve is wide open when the governor piston is about a third from the bottom of the cylinder and the engine running its proper speed. Should the engine speed increase, the governor piston rises and partly or entirely shuts off steam. Should the speed continue to increase with steam shut off (as may occur when putting materials down the pit) the further rise of the governor piston applies the brake partly or entirely as required. Assuming that the engine is running at its normal speed when the point arrives at which steam should be shut off, the first portion of one of the cams 11 gives sufficient motion to the lever m and thereby to the bell crank lever j1 carried by it to shut off the steam with the governor piston one-third from bottom, but if the engine speed had been above the normal the governor piston would have been higher and the steam would have been already partly or entirely shut off, and under these circumstances the motion imparted to the lever m would have either completed the shutting off a steam’and partly applied the brake or if steam were already entirely shut off the motion of the lever m would have fully applied the brake. On the contrary, if the engine had been running below speed with the governor piston there- fore lower, the motion of the lever m would have only partially shut off steam, and it would not be entirely shut off until the speed of the engine agreed with that which it should be during any part of the period of reduction of speed. The first motion of the lever m under the action of the cam also causes a slight reduction in the outlet orifice so that the governor will act on the throttle valve and brake at a lower speed of the engine, and thereafter the further motion of the lever m keeps adjusting the outlet orifice so that the governor can continue to control the engine at the speed due to the position of the cage in the shaft.
