Definitions

  • This invention relates to a clamp device and, more particularly, to a hinged clamping device for attaching a rail device to a railroad rail.
  • Fig. 1 shows a typical wiping bar assembly Wl mounted on a railroad rail 10.
  • the rail 10 includes a base 12 that has flanges 14 and 16 extending therefrom.
  • the rail 10 also includes a head 18, and a web 20 connecting the base 12 and the head 18.
  • the wiping bar assembly Wl is secured to the railroad rail 10 using a prior art mounting support or clamp 24.
  • a prior art mounting support or clamp 24 typically, it takes two spaced-apart mounting clamps 24 for securing a typical wiping bar assembly Wl to a railroad rail.
  • the wiping bar assembly typically may include a front blade extending lengthwise on the outside face of a lubricant manifold body and an elongated distribution blade extending lengthwise on the front blade.
  • a flow passageway is defined in a portion of the manifold body and the distribution blade for material to pass through.
  • the flow passageway defines an exit end for depositing material onto the head 18 of the rail 10.
  • the wiping bar assembly Wl is positioned to deliver material to the gage face of the head 18, although other wiping bar assembly Wl are utilized.
  • the mounting clamp 24 includes a body 26 having a first end 28 and a second end 30 and defining an upper section 32 and a lower section 34.
