Patent number: 5386784Abstract: A hand hold assembly and method for installation of the same on railroad car walls. The assembly has only three components, but can adapt to virtually any railroad car wall topography of the installation site. An elongated rod is bent or otherwise contorted and cut to fit the topography. Each end of the rod is mounted to the railroad car wall using one of two mounts, either a straight mount or an offset mount. If selected, the straight mount connects the end of the rod parallel to the railroad car wall, and the offset mount, if selected, connects the end of the rod perpendicular to the railroad car wall. The end of the rod is united to the selected mount by heating it, forging it into a bore of the mount and upsetting the end. Upon cooling, a steadfast union is formed. The new and improved assembly provides security and flexibility not before known in the art.Type: GrantFiled: June 7, 1993Date of Patent: February 7, 1995Inventor: Charles W. Meier
