  • the principal object oi' the present invention is to provide an improved construction of built-up welded axle box which obviates the use of cast metal, reduces the necessity of machining to a minimum, and ensures a strong and rigid but comparatively light structure,
  • Another object is to enable the horn guide plates to be readily machined to accurate dimensions before the axle box is built up.
  • a further-object is to ensure a more effective welding of the horn guide liners and cheek liners when such liners are fitted. 4
  • a still further object is to provide an axle box. of the kind referred to, which is eiectively sealed against the escape of lubricant, especially when lbongitudinal bolts pass through the ends of the Another object is to provide an axle box designed ior oil lubrication, which provides for the elective circulation of the oil without liability of leakage.
  • a built up welded axle box of the kind referred to has the outer frame or shell braced or attached to the tubular barrel or housing by means of a plurality of longitudinally-extending stay or gusset plates disposed in longitudinal planes above the below the axis of the axle box and welded at their inner and outer edges respectively to said tubular barrel or housing or to a part thereon and to the outer trame or shell.
  • the sides of the outer frame or shell may consist oi" ⁇ dat single plates which may form hornguide face plates adapted to be machinedto accurate dimensions before being secured in position on the tubular barrel or housing; or each of the said sides may consist of two or more plates welded to the side of the tubular barrel or housing as well as to vertical end plates.
  • the stay or gusset plates may be disposed between the inner faces'of the side plates and the tubular barrel or housing at points below and above the respective top and bottom edges of the plates; or they may be disposed at the corners ci' the box.
