When this valveis ojiened, though it be ever so little, the booster throttlegoes to a wide o\)cn position, if it moves at all; so that themovement of the idler into mesh with the gear is alwaysassured. The lubrication of the engine is effected by a splashsystem. The sixice beneath the shaft is filled with oil uptc a level with the guides. Cups are attached to thecranks and to the connecting rods bv which the oil is thrown over the working i>arts. In the case of the con-necting rod. a hole leads from the bottom of the cup tc-the crank i>in, so that as it scoojys into the oil the latter isforced back thn-ugh this hole to the inn, which it effec-tively lubricates. The total weight of the booster alone, as it rests on theaxles, is placed at 6,610 lbs., which is evenly divided be-tween the two axles. .As the driving axle is the leading one with referenceto the lx)ostcr. it rotates in the direction of the M. & L. Booster and Truck Complete when the engine is moving aliend. which means that thereis an upward thrust against the teeth of the pinion with acorresponding downward one on the engine frame. It isestimated that this thrust on the gear amounts to 29,690lbs. This it at a point 9 in. from the forward axle. As thewheelbase is 80 in. it means that of this 29,690 lbs. lbs. is transferred back to be carried by the tongueand the Ixilance by the main jcmrnals. These journals are 9 in. in diameter and 12 in. long, sothat their total projected area is 216 sq. in. They arethus burdened with a load of lbs., or only 137 sq. in. of projected area when the booster is at work. As to steam consumption, the steam gauge on \e was in full view of the observers during thewhole of the demonstration run and stood steadily at alittle above 200 lbs., showing that the
