Abstract: 2590. Lake, H. H., [Standard Steel Car Co.]. Feb. 3. Wagons.-Relates to various details of construction of metallic cars and especially of hopper cars. The side plates of the body are joined on the inside by metallic plates 56, Fig. 1, and on the outside by vertical trough-shaped stakes riveted to them. The plates are flanged at the top and bottom by angle-rails. The end plates are flanged at their lower ends and riveted to the inclined floor plates 46. The joints at the corners of the body are made by angle-irons. On the inside of the side plates are steps 57 to facilitate the passage of trainmen over the car. In the car of which Fig. 1 shows a section of one half, there are four hoppers arranged symmetrically with respect to the centre. The two on the left of the central transverse plane of the car are separated from the two on the right by a ridge formed by two oppositely-inclined plates 77 united by riveted flanges at their upper ends and tied to the sides of the car by inclined braces. The hoppers are closed by hinged doors 85 consisting of plates bent at three of their edges to form flanges, and fitted with an angle-iron along the fourth edge. The doors are connected in pairs by transverse beams 96. For supporting the ridge plates 77 at their centre they are connected to two vertical angleirons 83, which are riveted to the centre sills 1 and are tied together below the sills by an angle-iron 84. The centre sills 1 comprise two channel bars placed side by side with their flanges inwards ; they terminate near each end of the car beyond the body bolster 2. To the ends of the centre sills are riveted, by means of splice bars, draft sills 26, which are continued to the ends of the car. The draft sills consist of Z-shaped bars with the upper flanges turned inwardly except at the junction with the centre sills, where they are cut and bent flat against the sides of the centre sills. On the outer ends of the draft sills 26 is supported a Z-shaped end sill 25. Between the end sill and the ends of the body bolster 2 are fitted sub-side sills, which also consist of Z-shaped bars. One half of the body bolster is shown in Fig. 4. The central web plate 3 is divided at the centre of the car to allow of the passage of the centre sill 1. The tension member consists of angle-bars 4 riveted to the web plates 3 and running from side to side of the car above the centre sills. The compression member consists of angle-bars bearing at their inner ends on the centre sills and reinforced by a flat plate 7 passing under the centre sills. The two sections of the web plates are further tied together above the centre sills, and they are riveted to the sides of the centre sills by means of angle-irons ; they are continued up beyond the tension member 4, the upper extremities being flanged to form a support for the inclined floor of the car, as shown at 5, Fig. 1. In a modification, the tension member consists of a flanged or channel-shaped bar on one side of the web plates and a tie plate on the other side, the lower edge of the tie plate being flanged to rest upon the centre sill. In another modification, the tension member is riveted to the upper flanges of the centre sill, and the support for the floor of the car is a separate plate riveted to the tension member. To the end sill 25, Fig. 1, is attached a hood 35 consisting of a pressed steel plate having an opening for the passage of the shank of the draw-bar. The ends of the draft sills are embraced by the hood.
