Patent ID: 7673810

Claim:
A rail clip to be used with a rail clip support having a rail clip slot in a K plate, the rail clip being formed from a U shaped member made of metal plate having a base, a curved back and two tapered arms, said arms being bent inwardly beyond the base in a large arc and having tips that are bent back toward the base and oriented for contact with a foot of a rail and the base being adapted to fit in the slot of the rail clip support in the K plate, the base of said clip having a leading edge remote from said arms that contacts an upper interior surface of said slot to form a line of contact with a surface of said slot, which contact is achieved by spherical radii at front top corners of the clip base and these radii then converge to cylindrical radii and extend backwards towards a rear of the base and also outwards laterally and finally being truncated by vertical sides of the clip base.
