  • Patent number: 5613444
    Abstract: A railway truck includes a frame having a pair of side frames and laterally extending transoms therebetween. A plurality of journal boxes are resiliently suspended from the side frames and support a pair of longitudinally spaced apart end axles extending laterally between the side frames. A pair of longitudinally spaced apart bellcranks are rotatably joined to each of the side frames between the end axles, with each bellcrank having a vertical crankshaft and a crank arm extending outwardly therefrom. A pair of traction links extend longitudinally along each of the side frames, with each link being pivotally joined between respective ones of the journal boxes and the crank arms for carrying tension and compression loads therebetween. A pair of adjoining reaction arms extend longitudinally along each of the side frames, with each reaction arm having a proximal end fixedly joined to a respective one of the crankshafts, and distal ends thereof adjoining each other.

  • Patent number: 4188149
    Abstract: A skin welded joint comprising a thin metallic skin welded to a metallic frame member such as a metallic post or beam such as to substantially avoid local distortion, discoloration, and/or physical degradation of the skin and the resultant loss of appearance and/or strength. This skin welded joint comprises an elongated frame member, such as a post or beam, including one flange adjacent the skin, laterally spaced apart ribs projecting from one side of the flange and in contact with the skin, and a pair of flange portions integrally extruded with the ribs and the remainder of the elongated frame member. The flange portions laterally project on opposite sides of the flange, have a reduced thickness relative to the flange, for readily deformation under the heat of welding, and are welded to the skin.
