  • Patent number: 4454985
    Abstract: A device for clamping a railroad rail to a concrete tie includes a hollow vertical member which projects down into the tie alongside the rail and has an interior bearing surface which projects downwardly and inwardly toward the centerline of the tie. A generally C-shaped spring is disposed with its upper end abutting an upwardly facing surface on the rail and its center portion projecting down into the hollow member, the lower end of the spring abutting the bearing surface. A wedge acts between another interior bearing surface on the member and the center portion of the spring to flex the latter somewhat and cause the spring to clamp the rail tightly against the tie.
