The iron blocks, or buffers, arerounded only on the outer half, the inner section being flat, andare backed up by an 8 x io in. oak block, which bears directly school work from all parts of the U.

Experiments in a testing machine indicatedthat an oak block 8 in. thick could be compressed for I in. andwould recover, giving a diagram which was practically ideal fora friction draft gear. Thus after the buffer comes into contactit is estimated that the cushioning effect of this block for a dis-tance of I in. on each car will simply increase the draft gearcapacity for that distance. (This subject was discussed by P. C. Sanderson at the May meeting of the New York Rail-road Club.) The construction of the center plate and side bearings is shownin the illustration. Particular attention isdrawn to the provision for lubrication in bothof these places. The side bearing on the truckis of cast iron with a chilled face and is heldin place by a tottered bolt. Cast iron linersof varying thickness are fitted in the bottomof the pocket and permit adjustment for theproper clearance. The truck is of the regular arch bar type ofsome
