Abstract

See full text

Two rails, each having a straight edge, two ends and a cross section defining a channel, are placed in an end-to-end butting relationship to form a continuous straight edge. A joiner plate has an arcuate cross section and has lateral margins for being received in the rail channels. The plate is placed in the rail channels and is fastened to the rails so as to deflect the plate downwardly and force the lateral margins of the plate tight against the rails to align the rails and hold the rails together.
