Over the ties the flanges and G1 and G2 are beveled gear running idly in opposite directionswhen the load is off. I is the middle block, fastened rigidly tothe axle, and which is beveled ordinarily 3/16 in. to the inch. Pand P are beveled discs on one side and smooth, flat surfaceson the other, and while they admit of a lateral movement on theaxle they are held by keys or pins, i and t1, forcing them to re-volve with the axle. C and C1 are the outside discs, that arc-rigid on the axle, with a flat face lying against the corresponding.
