Welded Patents (Class 238/311)
  • Patent number: 5454514
    Abstract: A rail anchor assembly is provided with particularly-configured shoulder fittings welded to a base plate component in a manner which eliminates the necessity of weld grinding in order to assure non-interference between the shoulder fitting rail abutment end weld and a cooperating rail positioned upon the base plate component in proximity to the weld. The shoulder fitting rail abutment end includes an undercut which extends with increasing depth from the shoulder fitting rail abutment end vertical rail abutment face toward the rail retainer spring clip opening portion of the shoulder fitting to thereby form one side of a weld bevel groove accessible from within the shoulder fitting spring clip opening portion.
