Patent for improvements in rail-joint fastenings by providing “curved fish-plates with bearing-surfaces adapted to receive rubber washers, and the bolt has a slot through which the tapered split key is passed and the thin portion thereof turned up against the bolt to prevent displacement.” (Lines 20-25) Thus it will “securely retain in position, easily removed when desired, and [will] prevent rattling sounds as the cars pass over the rails.” (Lines 16-19) Illustration is included.
