Abstract: 12,397. Hansen, J. M. May 30. Wagons; under framing of bodies; doors, wagon.- A hopper wagon for ores or other heavy material is constructed as shown in half-sectional elevation in Fig. 3, and in transverse section in Fig. 5. The underframe consists of two longitudinal sills 1 extending from one body bolster to the other. Each body bolster is formed by a web plate 3, Fig. 4, with a pair of angle-bars 9 near its top edge, a pair of angle-bars 5 and a cover plate 6 along its bottom edge, and angle-bar stiffeners 8, 10. The web plate is cut away for the passage of the draught sills 4, which are preferably Z-bara and are riveted to the angle-bars 8 and the cover plate 6 and also to a channel beam, Fig. 3, riveted by one flange to the back of the plate 3. Short horizontal lengths of angle-bar 11 are also riveted to the front of the plate 3. The cover plate 6 is made to extend further to the rear of the bolster than to the front, as shown in Fig. 3, in order to leave more room for the draw-gear. The ends of the longitudinal sills 1 are riveted to the plate 6 and to the channel beam, and also to angle-pieces 13, Fig. 4, riveted to the web plate 3. The sides of the wagon are formed by vertical plates 15, Fig. 5, and inclined plates 16, which are continued downwards vertically between the sills 1 to form the sides of the discharge opening. The ends are formed by vertical plates 17, Fig. 3, and inclined plates 18. Angle-bars 20, with one flange extending outwards, are riveted round the top edges of the wagon sides and ends. The sides are stiffened by trough-section bars 21, Fig. 2, and angles 22. The bars 21 which are placed in line with the body bolsters are connected thereto by angle-pieces 23, Fig. 4, and gussets 24. The other stiffeners 21, 22, Fig. 2, are also continued downwards below the side plates 15 and are riveted to flanged bars 25, which form the tension members of the side sills, the compression members being formed by the side plates 15. Cantilever transoms consisting of angle-bars 26, Fig. 5, are placed between the sills 1 and the bars 25 in line with the stakes 21 and angle-bars 29 are riveted to the plates 16, the transoms 26, and the stakes 21. The discharge opening is divided into two by a diaphragm 31, Fig. 3, and each half is closed by two doors 32, 34, which are opened and closed by means of chains 35, Fig. 5, passing over pulleys 36 to a winding- shaft 37, Fig. 3, provided with a ratchet-wheel 39 and a detent 40, which can be disengaged by means of a cranked shaft 42 extending from side to side of the wagon and provided at each end with a handle 44, Fig. 2. Z-bars 50 connect the ends of the body bolsters to the ends of the end sills 51, Fig. 3, which are also, preferably, of Z-section. A hood 52 carrying the draw-bar carrier 53 is fixed to each sill 51. Diagonal braces extend from gusset plates at the ends of the end sills to the draught sills and body bolsters. Vertical anglebars 58, 59 are placed at the corners, and at intermediate points, to support the body ends. Diagonal braces 60 extend upwards from the corners of the underframe, and are secured to the side plates of the body and also to a transverse angle-beam 62.
