Abstract
A rail mounting assembly is disclosed including clip members which is some cases have formable portions for effecting engagement with a base plate to retain the clip member in position on a crosstie with the base plates on opposite sides of the rail being connected by an anchor means extending internally of the crosstie. Another aspect of the invention involves clip members and base plates having engageable serrated surfaces clamped together by a bolt received in a threaded anchor in a concrete crosstie so that loosening and subsequent tightening of the bolt permits the adjustment of the clip members with respect to the radial base flange and another embodiment in which a clip is held in position by a bolt in the anchor member in the crosstie with the clip having a coined surface canted at an angle to accommodate rail tilt and sawtooth serrations engaging the bolt head for preventing loosening of the bolt member.
