ABSTRACT:
A rail clamping device is provided for aligning and clamping the flange of a rail to a support surface. A slotted clip is fitted over an anchor bolt or other suitable connector, a plate cam washer having an eccentric hole is placed upon the clip, and a nut threaded upon the bolt to secure the clip and washer to the rail flange. The clip has a slotted base portion which slidably engages the support surface in a loose condition and bears upon the support surface in a clamped condition. An abutment portion extends from the base perpendicular to the support surface to engage the outer face of the rail flange. A cantilever portion extends forwardly from the abutment portion and has a bottom surface to which a synthetic rubber strip is bonded to engage the upper surface of the flange to clamp the flange to the supporting surface. The cam washer slidably engages the top surface of the base portion in a loose condition. The cam washer has an outer flank for engaging a rearward face of the abutment portion. Preferably, the cam washer has a spiral cam profile such that the angular rotation of the washer upon the bolt results in substantially proportional lateral movement of the clip and abutting rail flange. The rail flange may be aligned by rotation of the cam washers of devices on opposing sides of the rail when in a loose condition and then clamped securely in place by rotation of the nut.
