摘要:
A rail attachment assembly for attaching an end of a sinuous spring band to a steel rail. A vertical flange of the rail is provided with pairs of longitudinally spaced apertures to facilitate passage of anchor links or band elements. The steel rail section between the apertures in each pair is deformed inwardly of the flange to permit seating of the heavier gauge band segment or the lighter gauge link segment for rotation about a fixed axis. Where either a link or a spring is employed, noise, grinding and squeeking normally associated with uncontrolled vertical and/or lateral motion and travel of the link or springs; i.e., "wandering", is obviated.
