For along time there has been a desire both on the part of the manu-facturer and among street railway men to obtain solid forgings inthe place of steel. It is generally recognized that forgings for allordinary sizes are considerably superior in resistance to can be made lighter and much more shapely. The great ex-pense of forgings, however, has in most cases prevented their usefor such complex work as the No. 27 G side. By the most com-plexed system organized in the hammer department, the Brill com-pany has at last succeeded in producing a truck side of wroughtiron at a price closely approaching steel. The engraving repre-sents one of the first of these forgings. It will be noticed that the truck ends are dropped down very. WROUGHT IRON SIDE FRAME low upon the jaws; this is for the purpose of enabling the truckto radiate under open cars and to bring the truck side so low asto clear the steps. The forgings are very smooth, and have re-peatedly been mistaken for castings on account of their accuracyand the absence of hammer marks. Each jaw is fitted with a gibor wearing piece. This enables the jaws to be renewed to theiroriginal size with little difficulty and expense. Just inside of thejaw on the main bar are seen the seats for the links; these come sonear to the center line of the jaws that the weight of the body iscarried but a very short distance through the frame, practicallyless than 12 ins. The strains therefore in this important member ofthe truck frame are reduced to a minimum. Considered as a piece of blacksmith work this forging is quiteremarkable, and will command attention wherever it is seen byexperts in the handling of wrought iron. The fact that so com-plicate
