<p>A resilient rail clip or fastener formed in a generally trapezoidal configuration from springsteel is provided for securing rail track to railroad ties that may be constructed from a variety of materials, The trapezoidal shaped resilient rail clip has a long edge for gripping the rail which when untensioned forms a type of sine shaped curve and which when tensioned to the rail, utilizing two spikes or screws per clip, transforms the sine shaped curve into a linear line that is biased flat against the foot of the rail. The pressure of the two spikes or screws per clip in combination with the configuration of the springsteel dampen potentially harmful acceleration and deacceleration forces in the rail and frequency vibrations in the range of 800 to 1000 Hz which occur prior to and during train passage by absorbing and dissipating the forces while preventing lateral movement, creep, rotation and failure of the rail by utilizing the natural frequencies of the novel clip while minimizing track maintenance by reducing deterioration of the rail tie.</p> |
