Channel tic-bars connect the inner pedestals and short tie-bars connect each pair of tie-bars are bolted through the frame in such a man-ner that they form a rigid reinforcement to the pedestals,and by a simple device the shearing strain is entirely re-moved from the bolts. The short tie-bars can be readilyremoved and the wheels and axles dropped. The brake rigging is also of simple and substantial con-struction. The radial lever is brought around in a single. Half Plan and Side Elevation of Type Truck piece to the upright levers, thus reducing the usual numberof parts. It is supported by brackets and has a rub-platebolted to it to provide for wear, but as the bracket formsan extension to the frame, there is no weakening of theframe by bolt holes. The bolster is cast steel, including the lugs for the sidebearings, and rests on two elliptical springs which, in turn,bear on two-part castings in such a manner that shims canbe placed readily between the springs and the castings tocompensate for wheel wear. The chafing plates on the bol-sters and transoms can be taken off and renewed withoutremoving the bolster from the truck. Both of these feat-ures are designed to reduce maintenance charges. An addi-tional feature of the bolster chafing plate is its ample ver-tical dimension, which secures better support to the bolsteragainst tilting and insures uniformity of wear. A new and ingenious gib construction is used for the truck.
