. American engineer and railroad journal . frames, and to these pressed steel end sills are riveted, thidraft gear being secured to the center sills and passing throughthe end sills. The draft rigging is the Pressed Steel Car Com-panys standard twin spring arrangement. Stiffening anglesare riveted to the lower portions of the center and side sillsextending a considerable distance each way from the steel angles placed at 2 ft. liM/i-in. centers, rivetedbetween the webs of the center and side sills and the necessarybracing at the ends, complete the metal floor system. Three4 by 3-in. wooden stringers each side of the center of thecar and additional stringers at the side sills form the basisfor the floor and the box structure, as indicated in the draw-ings. The bolsters for the body and truck are of pressed Transverse Section. End Elevation. Pressed steel U-section carlines with pressed sockets for thepurlins are secured to the side plates at 5 ft. 3%-in centers,the plates being 8 by 3 ins. in section. A pressed steel angleextends along the outer upper corner of each side plate toform a secure attachment for the carlines. The posts andbraces are 5 by 2% ins. with diagonal rods, and the sidedoor posts are 5 by 5% ins. There are two 6 by Ts-in. beltrails and also one of pressed steel in U-section 4% ins. bolts securing the wood-work to the underframing are %in. diameter. These cars also have 2-ft. by 2-ft. 11-in. enddoors. Fox pressed sttel trucks, 33 in., 650 lbs. cast iron wheels,Buckeye coupler, with 6 by 6-in. shanks, cast iron journalboxes, pressed steel brake beams and Winslow roofs consti-tute the special equipment of the cars. 108 AMERICAN ENGINEER AND RAILROAD JOURNAL.
