. Electric railway journal . l and castings to which they arebolted, and which are in turn bolted to the side frames,also by steel plate gussets. The transom end castings alsoserve as wearing pieces between the bolster and tran-soms. A special design of gusset has been employed, thegussets on both sides of the transoms being pressed from asingle steel plate, which also forms an angle extendingalong the top of the frame on the inside for practically WAY JOURNAL. 1165 the entire length. This construction not only makes a veryrigid connection between frames and transoms, but alsoserves to stiffen the frames laterally. The swinging bolster is of strong, but light, construc-tion. It is pressed from a steel plate and weighs about200 lb. less than a cast-steel or built-up bolster of the samecapacity. It is carried on elliptic springs, while the truckframe is supported by coil springs on the journal boxes,one on the inside and the other on the outside of the frame,the load being thus uniformly distributed on the Truck Frame The elliptic springs supporting the bolster rest on cast-steel spring seats, riveted to the spring plank, which con-sists of two angles. These seats are provided with threesemi-circular pockets for the swing link pin or gib, so asto permit of adjusting the angularity of the swing link,in order to increase or decrease the resistance of the bol-ster to swinging by changing the swing link pin from onepocket to the other. These pockets are so designed thatthe position of the swing link pin does not alter the height
